A small company plans to invest in a new advertising campaign. There is a 20% chance that the company will lose $5,000, a 50% chance of a break even, and a 30% chance of a $10,000 profit. Based ONLY on this information, what should the company do? A) The expected value is $2,000.00, so the company should proceed with the campaign. B) The expected value is $4,000.00, so the company should proceed with the campaign. C) The expected value is −$2,000.00, so the company should not proceed with the campaign. D) The expected value is −$3,000.00, so the company should not proceed with the campaign.
A small company plans to invest in a new advertising campaign.
There is a 20% chance that the company will lose $5,000 ,
50% chance of a break even, and a 30% chance of a $10,000 profit
So the expected value from the advertisement campaign is calculated as - 20% of 5000 + 0% of 5000 + 30% of 10,000
= -1000 + 0 + 3000
= 2000
The expected value from the advertisement campaign is $2000.
So the Company must go ahead with the campaign.

A math teacher gave her students two tests. On the first test, 80% of the class passed the test, but only 30% of the class passed both tests.
What is the probability that a student passes the second test, given that they passed the first one?
0.256
0.375
0.500
0.625
Answer:
0.375 is answer
Step-by-step explanation:
Given that the math teacher gave her students two tests. On the first test, 80% of the class passed the test. But only 30% of the class passed both tests.
Let A - the students pass I test
B = students pass second test
Then P(A) = 80%=0.8 and P(AB) = 30% =0.30
Required probability =probability that a student passes the second test, given that they passed the first one
= P(B/A) = P(AB)/P(A)
= 0.30/0.80
=3/8
=0.375
Right answer is 0.375
The probability that a student passes the second test, given that they passed the first one, is 0.375.
The subject of this question is Mathematics, specifically focusing on the concept of conditional probability. The question asks about the probability that a student passes the second test, given that they passed the first one. Given that 80% of the class passed the first test and 30% passed both tests, we can use the formula for conditional probability P(B|A) = P(A and B) / P(A). Here, A represents passing the first test, and B represents passing the second test.
P(B|A) = P(A and B) / P(A) = 0.30 / 0.80 = 0.375.
Therefore, the probability that a student passes the second test, given that they passed the first one is 0.375.
Browning, montana, holds the u.S record for the greatest temperature drop in one day. On january 23, 1916, the temperature changed by an average of -4.17°f per hour. To the nearest degree, what was the total temperature change after 24 hours?
Answer:
Total temperature change 104.25 f.
Step-by-step explanation:
Average temperature change is calculated by dividing total temperature change by the total hours it took for the change.
We have been given the average temperature change.
We have to multiply average temperature change by the total number of hours it took for the temperature to change we get the total temperature change.
⇒ Total temperature change = Average temperature change * total hours
= [tex]-4.17*25[/tex]
=104.25 f

Alexis received an 85 89 and 92 and three test how many points does she need to score on your next test in order to have an average of at least 90
Lets say Alexis received 85, 89, 92, and x points in her four tests.
Average of a data set or the mean of a data set, we need to add all the values together and divide by the number of values in the set.
So here 85, 89, 92, and x are the values of the data set and the number of values are 4 (since there are 4 tests).
[tex]Avg=\frac{sum}{n}[/tex]
where 'n' represents the number of values and sum represents the total sum of the values.
Here we need to know how much Alexis need to score in her next test so that she can have an average of 90.
So we know the value of average that is 90.
Now,
[tex]90 = \frac{85+89+92+x}{4}[/tex]
Solving for 'x' we get:
[tex]90=\frac{266+x}{4}[/tex]
[tex]266+x=90 \times 4[/tex]
[tex]266+x=360[/tex]
Therefore,
[tex]x=360-266=94[/tex]
So, Alexis need to score at least 94 on her next test in order to have an average of at least 90.
You want to estimate the mean weight loss of people one year after using a popular weight-loss program being advertised on TV. How many people on that program must be surveyed if we want to be 95% confident that the sample mean weight loss is within 0.25 lb of the true population mean? Assume that the population standard deviation is known to be 10.6 lb.
Answer:
At least 6907 people.
Step-by-step explanation:
Population std deviation = sigma= 10.6
Since population std deviation is known, we can use normal probability table to get sample size from confidence interval.
The sample mean weight loss is within 0.25 lb of the true population mean.
Hence margin of error < 0.25
Margin of error = z critical (std dev/n) where n = sample size
Z critical for 95% = 1.96
Hence 0.25 >1.96(10.6)/sq rt n
Simplify to get
sq rt n > 1.96(10.6)/0.25 = 83.104
Square both the sides to get
n > 83.104 square = 6906.27
i.e. sample size should be atleast 6907.
Adam has been asked to post a parcel for a family member. He has been told that the parcel weighs 12lbs 8oz. How much does the parcel weigh to the nearest whole kilogram
Answer is 6 kg:
Given that Adam was asked to post a parcel. The weight of the parcel was 12 lbs and 8 oz.
To convert the weight in kgs:
Let us convert oz into pounds first to make it uniform.
We have 16 0z. = 1 lb
Hence 8 oz. = 8/16 = 0.5 lbs
Weight of the parcel = 12.5 lbs.
We have the converting factor as
2.2 pounds make 1 kg.
Hence 12.5 pounds = 12.5/2.2 = 5.6818
So weight of the parcel in kg= 6. (after rounding off)
Suppose the function, g(x), is used to model the height ,y, of a soccer ball, x seconds after the ball is kicked up in the air. The ball starts on the ground and travels in a parabolic shape as it reaches a maximum height and then returns to the ground. Suppose further that the ball reaches its maximum height of 15 feet in 2.2 seconds. What would be an appropriate domain for g(x)?
A. 0<=x<=2.2
B. -2.2<=x<=2.2
C. 0<=x<=4.4
D. 0<=x<=15
Answer:
The correct option is C.
Step-by-step explanation:
The height of the ball is defined by a parabolic function.
Let the equation of the parabola is
[tex]f(x)=a(x-h)^2+k[/tex]
Where, (h,k) is the vertex and a is stretch factor.
The maximum height of the ball is 15 feet in 2.2 seconds. So, the vertex is (2.2, 15).
The equation of the parabola is
[tex]f(x)=a(x-2.2)^2+15[/tex]
The initial height of the ball is 0.
[tex]f(0)=a(0-2.2)^2+15[/tex]
[tex]0=a(-2.2)^2+15[/tex]
[tex]a=-\frac{15}{(2.2)^2}[/tex]
[tex]a=-3.1[/tex]
The equation of the parabola is
[tex]f(x)=-3.1(x-2.2)^2+15[/tex]
The function takes 2.2 seconds to reach at maximum height, so after that it will take 2.2 seconds to reach at growth again.
[tex]2.2+2.2=4.4[/tex]
The ball will reach the growth at x=4.4.
The height can not be negative, therefore the value of x lies between 0 to 4.4. The domain of the function is
[tex]0\leq x\leq 4.4[/tex]
Therefore option C is correct.
Mary has two bags of sweets, each of which contains the same number of sweets. She eats four sweets. She then finds that she has 30 sweets left. How many sweets were in each bag to start with?
Given that Mary has 2 bags of sweets. each of which contains same number of sweets.
Let us assume each bag contains x number of sweets.
After eating 4 sweets, total number of sweets left in two bags = x+x-4=2x-4
But given 2x-4 = 30
2x-4+4 = 30+4
2x=34
[tex]x=\frac{34}{2} = 17[/tex]
Hence there are 17 sweets in each bag at starting.
Mary had two bags with an equal number of sweets. After eating 4 sweets, she had 30 left, which means each bag originally contained 17 sweets.
To solve the problem of determining how many sweets were in each bag to start with, we must consider that Mary had two bags with an equal number of sweets and ended up with 30 sweets after eating 4 sweets. We can represent the initial number of sweets in each bag as 'x'. So the equation for the total number of sweets after she eats 4 is 2x - 4 = 30.
Let's solve this equation step by step:
Add 4 to both sides: 2x = 30 + 4
Simplify: 2x = 34
Divide both sides by 2 to solve for x: x = 34 / 2
Therefore, x = 17
This means that initially, there were 17 sweets in each bag.

How is the divisibility rule for 7 more complicated then the rules for 2,3,5 and 10?
Final answer:
The divisibility rule for 7 is more complex than the rules for 2, 3, 5, and 10 due to the lack of a simple pattern or quick digit check, requiring multiple steps and manipulations of the number.
Explanation:
The divisibility rule for 7 is more complicated than the rules for 2, 3, 5, and 10 because it does not follow a simple pattern or involve a quick check of a number's last digit or sum. The rules for divisibility by 2, 3, 5, and 10 are straightforward: a number is divisible by 2 if its last digit is even, by 3 if the sum of its digits is divisible by 3, by 5 if its last digit is 0 or 5, and by 10 if it ends in 0.
The rule for divisibility by 7 requires more steps and cannot be easily performed in one's head. The process typically involves subtracting or adding multiples of 7 from different segments of the number, which often makes it more difficult for students to use effectively without practice or further understanding of the method. Complicated rules for divisibility by 7 prove the point that while mathematical rules are universally valid, some rules are inherently more complex than others.

Which of the following fractions is equivalent to -84/-90 in the least common terms?
14/15
(-)14/15
42/45
(-)42/45
The fraction equivalent to -84/-90 in the least common terms is 14/15, as both the numerator and the denominator can be divided by the common factor 6, resulting in a simplified positive fraction.
To find which fraction is equivalent to -84/-90 in the least common terms, we need to simplify the fraction by canceling out any common factors in the numerator and the denominator. We observe that both numbers are divisible by 6. When we divide the numerator and the denominator by 6, we get:
-84 / -90 = (-84 / 6) \/ (-90 / 6) = 14 / 15
Since a negative divided by a negative results in a positive number, we eliminate the negative signs and get the fraction in its least common terms as 14/15.

Ming took a cab across town. His fare was \$22$22dollar sign, 22, and he leaves an 18\%18%18, percent tip.
Answer:
$25.96
Step-by-step explanation:
We have been given that Ming took a cab across town. His fare was $22, and he leaves an 18% tip.
To find the total amount by Ming for cab ride will be equal to 22 plus 18% of 22.
[tex]\text{Total amount paid by Ming for the cab ride}=22+(\frac{18}{100}*22)[/tex]
[tex]\text{Total amount paid by Ming for the cab ride}=22+(0.18*22)[/tex]
[tex]\text{Total amount paid by Ming for the cab ride}=22+3.96[/tex]

Therefore, Ming paid a total amount of $25.96 to the cab driver.
Airbags are manufactured by Aces (A), Best (B), and Cool (C) at rates of 57%, 26% and 17%, respectively. Airbags occasionally kill (K) passengers when they deploy in accidents. Airbags made by Aces, Best, and Cool do not kill people at rates of 99%, 96%, and 87%, respectively. One airbag is randomly selected for testing.
If an airbag kills a passenger, calculate the probability that the airbag was manufactured by Cool. (Round to the nearest ten-thousandth.)
Air bag manufactured by Aces(A)=57%
So, Probability [tex]P(A)=\frac{57}{100}[/tex]
Air bag manufactured by Best (B) =26%
So, Probability [tex]P(B)=\frac{26}{100}[/tex]
Airbag manufactured by Cool(C)=17%
So, Probability [tex]P(C)=\frac{17}{100}[/tex]
Airbags made by Aces, Best, and Cool do not kill people at rates of 99%, 96%, and 87%, respectively.
Let K be the event which kill people.
Probability of Air bag made by A which kill people [tex]P(K/A)=\frac{1}{100}[/tex]
Probability of Air bag made by B which kill people [tex]P(K/B)=\frac{4}{100}[/tex]
Probability of Air bag made by C which kill people [tex]P(K/A)=\frac{13}{100}[/tex]
If an airbag kills a passenger, calculate the probability that the airbag was manufactured by Cool
Using Baye's theorem:
[tex]P(C/K)=\frac{P(K/C)P(C)}{P(K/A)P(A)+P(K/B)P(B)+P(K/C)P(C)}[/tex]
Substitute the values of probabilities into formula
We get,
[tex]P(C/K)=\frac{0.17\times 0.13}{0.57\times 0.01+0.26\times 0.04+0.17\times 0.13}[/tex]
Now we calculate it and get probability
So, [tex]P(C/K)=0.5785[/tex]
So, 57.85% of passenger kills if the airbag was manufactured by Cool.

Enter your answer in the box.
Answer:
The factor form of given expression is (x-4)(x-2i)(x+2i).
Step-by-step explanation:
The given expression is
[tex]x^3-4x^2+4x-16[/tex]
It can be written as
[tex]f(x)=x^3-4x^2+4x-16[/tex]
According to the rational root theorem, all possible rational roots are in the form of
[tex]\frac{a_0}{a_n}[/tex]
Where, a₀ is constant term and [tex]a_n[/tex] is leading coefficient.
[tex]f(4)=4^3-4(4)^2+4(4)-16=0[/tex]
Since the value of f(x) is 0 at x=4, therefore 4 is a root of the function and (x-4) is a factor of given expression.
Use synthetic method to find the remaining factors.
[tex](x^3-4x^2+4x-16)=(x-4)(x^2+4)[/tex]
[tex](x^3-4x^2+4x-16)=(x-4)(x^2-(2i)^2)[/tex]
[tex](x^3-4x^2+4x-16)=(x-4)(x-2i)(x+2i)[/tex]
Therefore the factor form of given expression is (x-4)(x-2i)(x+2i).
Answer:
(x-4) (x-2i) (x+2i)
Step-by-step explanation:
x^3−4x^2+4x−16
I will factor by grouping
x^3−4x^2+ 4x−16
The first group is the first 2 terms. I can factor out an x^2
x^2 (x-4) + 4x-16
The second group I can factor out a 4
x^2 (x-4) + 4(x-4)
Now I can factor out (x-4)
(x-4) (x^2 +4)
We know that x^2 + 4 factors into +2i and -2i because
(a^2 -b^2) = (a-b) (a+b) but we have (a^2 + b^2) = (a-bi) (a+bi)

Final answer:
To calculate the average monthly weight loss of the black bear, divide the total weight loss by the number of hibernation months. The bear lost 0.1 pound per month during its 712 months of hibernation.
Explanation:
To find the average weight loss per month of the black bear, you need to divide the total weight loss by the number of months of hibernation. The black bear lost 64.4 pounds over 712 months.
First, we write out the calculation needed:
64.4 pounds ÷ 712 months.
When you perform the division, you get approximately 0.0904494382 pounds per month. Rounding to the nearest tenth gives us 0.1 pounds per month.
Therefore, the bear experienced an average weight change of 0.1 pound per month during hibernation.

Use the figure to answer the question that follows:
Segments UV and WZ are parallel with line ST intersecting both at points Q and R respectively
When written in the correct order, the two-column proof below describes the statements and reasons for proving that corresponding angles are congruent:
Statements Reasons
segment UV is parallel to segment WZ Given
Points S, Q, R, and T all lie on the same line. Given
I m∠SQT = 180° Definition of a Straight Angle
II m∠SQV + m∠VQT = 180° Substitution Property of Equality
III m∠SQV + m∠VQT = m∠SQT Angle Addition Postulate
m∠VQT + m∠ZRS = 180° Same-Side Interior Angles Theorem
m∠SQV + m∠VQT = m∠VQT + m∠ZRS Substitution Property of Equality
m∠SQV + m∠VQT − m∠VQT = m∠VQT + m∠ZRS − m∠VQT
m∠SQV = m∠ZRS Subtraction Property of Equality
∠SQV ≅ ∠ZRS Definition of Congruency
Which is the most logical order of statements and reasons I, II, and III to complete the proof?
The correct logical order for the statements I, II, and III in the proof is: I. Definition of a Straight Angle, III. Angle Addition Postulate, and II. Substitution Property of Equality. This order supports the conclusion that corresponding angles, created by the transversal intersecting parallel lines, are congruent.
To complete the two-column proof that demonstrates the congruence of the corresponding angles when segments UV and WZ are parallel and line ST intersects both at points Q and R respectively, we need to place statements and reasons I, II, and III in the most logical order. This should allow us to show
corresponding angles are congruent, which is the ultimate aim of the proof.
The correct order of statements and reasons to complete the proof is:
Definition of a Straight Angle (I): We know that the angle measure of a straight line is 180°, hence m∠SQT = 180°.
Angle Addition Postulate (III): Based on the postulate, we can express m∠SQV + m∠VQT as equal to the measure of angle SQT because the two angles combine to form the straight angle, therefore m∠SQV + m∠VQT = m∠SQT.
Substitution Property of Equality (II): By substituting the equal values established in statements I and III, we get m∠SQV + m∠VQT = 180°.
After arranging the statements and their corresponding reasons, the proof logically demonstrates that the congruent angle pairs are a result of transversal ST intersecting parallel lines UV and WZ.

[tex]a_n=a_{n-1}-3\\\\a_1=8\\\\a_2=a_1-3\to a_2=8-3=5\\\\a_3=a_2-3\to a_3=5-3=2\\\\a_4=a_3-3\to a_4=2-3=-1\\\\a_5=a_4-3\to a_5=-1-3=-4[/tex]
To find the value of a5, we subtract 3 repeatedly from the previous value starting with a1=8. After iterating this process four times, we find that a5 equals -4.
The sequence given is defined by a1 = 8 and an = an-1 - 3. To find a5, we need to apply the formula recursively starting from a1:
a2 = a1 - 3 = 8 - 3 = 5
a3 = a2 - 3 = 5 - 3 = 2
a4 = a3 - 3 = 2 - 3 = -1
a5 = a4 - 3 = -1 - 3 = -4
So, the value of a5 is -4.
Marissa is an event organizer for a charity group. She is organizing a five-hour dinner event being held to raise funds for the charity. The following list shows the costs for hosting the event. Facility Rental: $150 per hour of event Linens: $2 per attendee Food: $20 per attendee Table Decorations: $3 per attendee Musical Entertainment: $1,800 (flat fee) Cleaning Fee: $250 (flat fee) The total cost of the event, with n attendees, is represented by the given expression. Which statement best describes the constant in this expression?
A constant is a number that stays the same no matter what any outside variables are. In this case, the variables are the number of hours of the event and the number of attendees. However, it states in the problem that the event will be 5 hours so that becomes known; the only thing that might change is the number of attendees so you can eliminate any cost that will be affected by that. You are left with Facility Rental, Musical Entertainment, and Cleaning Fee. Furthermore, you can be sure that Musical Entertainment and Cleaning Fee must be included in the constant because they are described as "flat rates", which means they do not change.
The answer is D) It is the total cost for entertainment, facility rental, and cleaning.
Hope this helps!

It is the cost per person for food, linens, and food decorations.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Facility Rental = $150 per hour of the event
Linens = $2 per attendee
Food = $20 per attendee
Table Decorations = $3 per attendee
Musical Entertainment = $1,800
Cleaning Fee = $250
The total cost of the event.
= 25n + 2,800
Where n is the number of attendees.
Now,
25 is the total cost per attendee for food, linens, and table decorations.
Thus,
The constant in the expression is 25 which is the cost per attendee for food, linens, and table decorations.
