Answer:
D
Step-by-step explanation:
If the lines are parallel, the slope of both of them are going to be the same. So if one line is 3, the other one will be too.
The answer is:
If the red line has a slope of 3, the slope of the red line will also be 3.
So, the correct option is, D. 3
Why?We need to remember that if two or more lines are parallel, they will share the same slope, no matter where are located their x-intercepts and y-intercepts, the only condition needed for them to be parallel, is to have the same slope.
So, if two lines are parallel, and one of them (the red line) has a slope of 3, the slope of the other line (the green line) will also be 3.
Have a nice day!

Answers
Answer:
the balance of Osborn’s Equity Investment (Shea) account be at the end of 2017 is $233,500
Step-by-step explanation:
Given data
Acquistion price = $220000
purchased = 30%
net income = $75,000
cash dividends = $30,000
to find out
the balance of Osborn’s Equity Investment (Shea) account be at the end of 2017
solution
we will find out balance of investment i.e. given by formula
balance of investment = Acquistion price + share of income - share of dividend .................1
so here
share of income = 30% of net income
share of income =30% × 75,000 = $22500 ..............2
and
share of dividend = 30% of cash dividends
share of dividend = 30% × 30000 = $9000 ...............3
put equation 2 and 3 in equation 1 and we get
balance of investment = Acquistion price + share of income - share of dividend
balance of investment = 220000 + 22500 - 9000
balance of investment = $233,500

Then the probability for that there are at least 3 weeks of no sick students before the 2nd week of at least one sick student is given by:
[tex](\frac{17}{23})(\frac{17}{23})(\frac{17}{23})(\frac{17}{23}) + \frac{6}{23} + 3(\frac{17}{23})^{3}\\ = 0.614[/tex]
What must the total momentum of the system be after the train cars collide?
Answers
Answer:
The total momentum of the system remains the same.Momentum before collision is equal to momentum after collision
Step-by-step explanation:
Momentum is defined as the product of mass and velocity of the bodies.According to the law of conservation of momentum, a collision that occurs in an isolated system, the momentum before collision equals that after collision.After collision, the bodies can move in the same direction thus their momentum is combined.
Answer:
The total momentum must remain the same.According to the law of conservation of momentum, in a system where particles collide, the momentum loss on one particles is gained by the other one. This is what create an reaction during the collision, for example, if two bodies collide, one will decrease its speed while the other will increase its speed, that's why the momentum is conserved.
So, basically, after the train cars collide, the momentum must be conserved, remaining the same.

Answers
Step-by-step explanation:
10.
First, convert 1+i from Cartesian to polar.
r = √(1² + 1²)
r = √2
θ = atan(1/1), θ in first quadrant
θ = 45°
Therefore:
(1+i)²⁰ = (√2 (cos 45° + i sin 45°))²⁰
(1+i)²⁰ = 1024 (cos 45° + i sin 45°)²⁰
Now applying the De Moivre theorem:
1024 (cos (20×45°) + i sin (20×45°))
1024 (cos (900°) + i sin (900°))
1024 (-1 + 0)
-1024
11.
Repeat the same steps from Question 10. First, convert to polar:
r = √(1² + (-1)²)
r = √2
θ = atan(-1/1), θ in fourth quadrant
θ = 315°
Therefore:
(1−i)¹⁰ = (√2 (cos 315° + i sin 315°))¹⁰
(1−i)¹⁰ = 32 (cos 315° + i sin 315°)¹⁰
Now applying the De Moivre theorem:
32 (cos (10×315°) + i sin (10×315°))
32 (cos (3150°) + i sin (3150°))

Find the equation for the horizontal line and the vertical line passing through ( − 10 , 7 )
Answers
Answer:
Step-by-step explanation:
Horizontal lines have the form " y = " where vertical lines have the form " x = ".
Horizontal lines run parallel to the y = 0 line, the x-axis, so horizontal lines are found in the y coordinate of the point. Therefore, the horizontal line at that point is y = 7.
The vertical lines run parallel to the y-axis, which is the line x = 0. The vertical lines are found then in the x coordinate of the point. Therefore, the vertical line at that point is x = -10

Sue graphed the formula for converting temperatures from Fahrenheit to Celsius. If the temperature is 50 degrees Fahrenheit, what is the temperature in Celsius? 5 degrees Celsius 10 degrees Celsius 15 degrees Celsius 20 degrees Celsius
Answers
Answer:
Second Option (10° Celsius)
Step-by-step explanation:
There is a formula to convert the temperature which is in degree Celsius into degree Fahrenheit and vice versa. The formula to convert the temperature in degree Fahrenheit into degree Celsius is:
C° = (F° - 32) * 5/9.
It is given that the temperature is 50° Fahrenheit. Therefore, F° = 50°. Substituting F° = 50° in the formula gives:
C° = (50° - 32) * 5/9.
Further simplification results in:
C° = 18 * 5/9. Therefore, C° = 10°.
So the correct answer is 10° Celsius!!!

Step-by-step explanation:
* Lets explain how to solve this problem
- The function f(x) = e^x is called the (natural) exponential function
- The natural logarithm (㏑), or logarithm to base e, is the inverse
function to the natural exponential function
∵ [tex]e^{2x+5}=4[/tex] is an exponential function
∴ We can solve it by using the inverse of e (㏑)
- Remember:
# [tex]ln(e)=1[/tex]
# [tex]ln(e^{m})=m(ln(e))=m[/tex]
- Insert ln in both sides
∴ [tex]ln(e^{2x+5})=ln(4)[/tex]
∵ [tex]ln(e^{2x+5})=(2x+5)ln(e)=2x+5[/tex]
∴ 2x + 5 = ㏑(4)
- Subtract 5 from both sides

Hence, the formula to solve r is [tex]r=\sqrt[3]{\frac{GMT^{2}}{4\pi^{2}}}[/tex].
The following chart represents the record high temperatures recorded in Phoenix for April - November. Select the answer below that best describes the mean and median of the data set ( round answers to the nearest tenth)
A. The mean is 114.5F and the median is 111.9F.
B. The mean is 121F and the median is 118.5F.
C. The mean is 111.9F and the median is 114.5F.
D. The mean is 118.5F and the median is 121F
Answers
Answer:
C. The mean is 111.9F and the median is 114.5F.
Step-by-step explanation:
The mean is 111.9 given that (105 + 113 + 122 + 121 + 116 + 118 + 107 + 93)/8 = 111.875 which can be rounded to 111.9 F.
Organizing the values we have:
[93, 105, 107, 113, 116, 118, 121, 122]
We find that the median is going to be between 113 and 116. Therefore:
(113 + 116) / 2 = 114,5
Therefore, the correct answer is option C.
The answer would be "C"
mean = 111.9F
median = 114.5F
For the mean, we would add up all the numbers in the data. In this case, we would add...
105 + 113 + 122 + 121 + 116 + 118 + 107 + 93 = 895
Next, we would divide the sum by the number of bars we have in the graph. There are 8 bars in the graph with 8 different temperatures so we would divide 895 by 8 and we will get a quotient of 111.875. 111.875 rounded to the nearest tenths place is 111.9F
For the median, we would first place all the numbers in order from least to greatest.
least to greatest- 93,105,107,113,116,118,121,122
next, we need to find the two middle numbers because there is no middle number in an even set of data.
The two middle numbers in the data set are 113 and 116. The halfway point between 113 and 116 is 114.5 so our median would be 114.5
Let the sample space be S = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}. Suppose the outcomes are equally likely. Compute the probability of the event E={2, 4}.
Answers
Answer:
0.2
Step-by-step explanation:
we have given sample space = {1,2,3,4,5,6,7,8,9,10}
favorable outcomes E={2,4}
we know that probability is defined as the ratio of favorable otcomes to the sample space
probability [tex]P=\frac{favorable\ outcomes}{ sample\ space }[/tex]
we have favorable outcomes E={2,4} that is favorable outcomes=2
and sample sapce = {1,2,3,4,5,6,7,8,9,10}
so the probability [tex]p=\frac{2}{10}=0.2[/tex]
The probability of event E={2,4} from the sample space S={1,2,3,4,5,6,7,8,9,10} is 1/5 or 20%, calculated by dividing the number of favorable outcomes (2) by the total number of outcomes (10).
Explanation:The student asked to compute the probability of event E={2,4} from a sample space S={1,2,3,4,5,6,7,8,9,10}. Since the outcomes are equally likely, we use the formula for theoretical probability, which is the number of favorable outcomes divided by the total number of possible outcomes in the sample space.
To find P(E), first count the number of outcomes in event E, which includes just 2 and 4. There are two favorable outcomes. The total number of outcomes in the sample space S is 10. Therefore, P(E) equals 2/10 or 1/5 when simplified. This means the probability of event E occurring is 0.20 or 20%.

The distribution of heights of women for a certain country is approximately Normal, with a mean of 63.6 inches and a standard deviation of 2.8 inches. How tall are the shortest 15% of all women in this country?
Answers
Answer: 66.50 inches
Step-by-step explanation:
Given : The distribution of heights of women for a certain country is approximately Normal with ,
[tex]\mu=\text{63.6 inches }\\\\\sigma=\text{2.8 inches}[/tex]
To find the height of the shortest 15% of all women, first we need to find the z-score corresponding to the p-value 0.15 from the standard normal distribution table, we get 1.0364.
Let x be the random variable that represents the height of the randomly selected woman.
Then[tex]z=\dfrac{x-\mu}{\sigma}[/tex]

One zero of the polynomial function f(x) = x3 + x2 + 20x is x = 0. What are the zeros of the polynomial function?
0, −5, −4
0, −5, 4
0, 5, −4
0, 5, 4
Answers
The zeros of the polynomial function f(x) = x^3 + x^2 + 20x are 0, -5, -4.
Explanation:The zeros of a polynomial function are the values of x that make the function equal to zero.
We are given that one zero of the polynomial function f(x) = x^3 + x^2 + 20x is x = 0.
To find the other zeros, we can use polynomial long division or synthetic division to factor out x = 0 and find the remaining quadratic equation.
Factoring the quadratic equation, we find that the zeros are x = -5 and x = -4.
Therefore, the correct answer is 0, -5, -4.
Final answer:
The zeros of the polynomial function f(x) = x^3 + x^2 + 20x are 0, -5, and -4.
Explanation:
The zeros of a polynomial function are the values of x that make the function equal to zero. Given that one zero of the polynomial function f(x) = x^3 + x^2 + 20x is x = 0, we need to find the other zeros. To do this, we factor the polynomial using synthetic division or long division. In this case, the factored form of the polynomial is f(x) = (x)(x + 5)(x + 4). Therefore, the zeros of the polynomial function are 0, -5, and -4.

Answers
Answer:
A. Points A, B, and D are on both planes. B. Point H is not on plane R. D. Points C, D, and A are noncollinear. E. The line containing points F and G is on plane R.Step-by-step explanation:
A. Points A, B, and D are on both planes.
-- true. These points are on the line of intersection of the planes, so are in both planes.
B. Point H is not on plane R.
-- true. Point H is not shown as being on either of the identified planes.
C. Plane P contains point F.
-- false. Point F is shown as being in plane R, not P.
D. Points C, D, and A are noncollinear.
-- true. Point C is not on the line containing points A and D.
E. The line containing points F and G is on plane R.
-- true. F and G are both in plane R, so the line containing them will also be in that plane.
F. The line containing points F and H is on plane R.
-- false. Point H is not in plane R, so will not be on any line in plane R.

What polynomial has roots of −6, −4, and 1?
x3 − 9x2 − 22x + 24
x3 − x2 − 26x − 24
x3 + x2 − 26x + 24
x3 + 9x2 + 14x − 24
Answers
Answer:
x^3+9x^2+14x-24 has roots of -6,-4 and 1
Option D is correct
Step-by-step explanation:
If the polynomial has roots of -6 -4 and 1
then x=-6, x=-4, x=1
Which can be written as:
(x+6)(x+4)(x-1)
Multiplying we get,
(x+6)(x(x-1)+4(x-1))
(x+6)(x^2-x+4x-4)
(x+6)(x^2+3x-4)
x(x^2+3x-4)+6(x^2+3x-4)
x^3+3x^2-4x+6x^2+18x-24
x^3+3x^2+6x^2-4x+18x-24
x^3+9x^2+14x-24
So, x^3+9x^2+14x-24 has roots of -6,-4 and 1
Option D is correct
Expand this, and see which answer choice matches it
(x-1)(x^2 - 10x + 24)
Expanding it the rest of the way and determining the answer has been left as an exercise for the reader.
Fred and Gina are playing tennis. The first player to win 2 sets wins their match. Fred has a 3/5 chance to win each set while Gina has a 2/5 chance. What is the probability that the match is decided in only two sets?
Answers
From the information below the games is over in 3 sets. For Gina to win the match there are 3 possibilities.
1) Gina wins the first 2 sets with probability
2)Gina wins the first set. Looses the next set. Wins the third set.
3)Gina looses the first set. Wins the next 2 sets.
The required probability that Gina wins is the sum of the above 3 probabilities . That is the probability that Gina wins the match is
Answer:[tex] P=\frac{9+4}{25}=\frac{13}{25}[/tex]
Step-by-step explanation:
Given
Fred has a chance of 3/5 to win
and Gina has a chance of 2/5 to win
Probability(P) that the match is decided in only two sets is when
Either Fred or Gina win both matches continuously
P=P(Fred win both match)+P(Gina win both match)
[tex]P=\frac{3\times 3}{5\times 5}+\frac{2\times 2}{5\times 5}[/tex]
[tex] P=\frac{9+4}{25}=\frac{13}{25}[/tex]
