in a game of tug of war your team changes -1 3/10 feet in position every 10 seconds. What is your change in position after 30 seconds?
To calculate the change in position after 30 seconds, multiply the rate of change per 10 seconds, which is -1 3/10 feet, by the number of 10-second intervals in 30 seconds, resulting in a total change of -3 9/10 feet or -3.9 feet.
If your team changes its position by -1 3/10 feet every 10 seconds in a tug of war game, we need to find out the change in position after 30 seconds.
Since the change in position is consistent over time, we can calculate the total change by multiplying the rate of change per 10 seconds by the number of 10-second intervals in 30 seconds.
The number of 10-second intervals in 30 seconds is:
30 seconds / 10 seconds per interval = 3 intervals.
The total change in position is then:
-1 3/10 feet/change × 3 changes = (-1 × 3)+(3/10 × 3)
= -3 9/10 feet or -3.9 feet.
Your team's change in position after 30 seconds is -3 9/10 feet or -3.9 feet.

(-8)-(6+30i) Express your answer in the form (a+bi)
Answer:
-14 - 30 i
Step-by-step explanation:
We recall that when combining complex numbers, we need to combine the real parts among themselves to get the new real part, and the imaginary parts among themselves to get the imaginary part of the new complex that results from the operation.
In our case the firs complex number is "-8" which consists of strictly real part (with zero imaginary part). The second complex number is (6+30 i) which has real part = 6 and imaginary part = 30 i.
now we operate separately on the real parts and on the imaginary parts performing the requested subtraction:
Real part: -8 - 6 = -14
Imaginary part: 0 i - 30 i = -30 i
Therefore the final complex number that results from this subtraction is: "-14 - 30 i"

h =
Answer:
(a) The equation is [tex]7h-2=56[/tex].
(b) Trey gets approximately $8.29 for each hour of work.
Step-by-step explanation:
Given:
Number of hours Trey works = 7
Amount of money he put aside for mom = $2
Total Amount he keeps each day = $56
We need to find the amount he gets for each hour.
Let 'h' represent the amount (in dollars) Trey gets paid each hour.
Solving for part (a).
We need to write the equation to find the amount he gets paid for each hour.
Now we can say that;
Total Amount he keeps each day is equal to Number of hours Trey works multiplied by the amount he gets paid for each hour minus Amount of money he put aside for mom.
framing in equation form we get;
[tex]7h-2=56[/tex]
Hence the equation is [tex]7h-2=56[/tex].
Solving for part (b).
we need to solve the above equation to find the amount he gets paid for each hour.
On solving the equation we get;
Adding both side by 2 we get
[tex]7h-2+2=56+2\\\\7h=58[/tex]
Now Dividing both side by 7 using Division Property we get;
[tex]\frac{7h}{7} = \frac{58}{7}\\\\h \approx \$8.29[/tex]
Hence Trey gets approximately $8.29 for each hour of work.
Consider the net of a triangular prism where each unit on the coordinate plane represents four feet. If a sheet of plywood measures 4 ft x 8 ft, how many sheets of plywood will a carpenter need to build the prism?
A) 2
B) 3
C) 4
D) 5
Answer:
2 sheets of plywood will be needed.
Step-by-step explanation:
See the attached diagram.
Each three square plywood has area 1 units by 3 units = 4 feet by 12 feet = 48 feet square. {Since each unit on the coordinate plane represents four feet}
Now, the two triangular plywood has area half of a unit square area.
So, two triangular plywood has total area = 1 unit by 1 unit = 4 feet by 4 feet = 16 feet square.
Therefore, the total area of plywood required to make the triangular prism is (48 + 16) = 64 feet square.
Now, if a sheet of plywood measures 4 ft by 8 ft i.e. 32 feet square, then the carpenter will need [tex]\frac{64}{32} = 2[/tex] such sheets of plywood. (Answer)

When Julia is writing a first draft, there is 0.7 probability that there will be no spelling mistakes on a page. One day, Julia writes a first draft that is 4 pages long. Assuming that Julia is equally likely to have a spelling mistake on each of the 4 pages, what is the probability that she will have no spelling mistakes on at least one of them?
Answer:
The required probability is given by, 0.9919.
Step-by-step explanation:
Let, X be the random variable denoting the no. of pages among those 4 pages which Julia writes where she makes no spelling mistake.
clearly,
X [tex]\sim[/tex] Binomial (4, 0.7)
So, P(X = x) = [tex]^4C_{x} \times (0.7)^{x} \times (0.3)^{(4 - x)}[/tex]
[when x = 0, 1, 2, 3, 4]
= 0 otherwise
According to the question, we are to find out P(X ≥ 1) .
Now, P(X ≥ 1)
= 1 - P(X = 0)
= [tex] 1 - (^4C_{0} \times (0.7)^{0} \times (0.3)^{4})[/tex]
= [tex] 1 - 0.0081[/tex]
= 0.9919
So, the required probability is given by, 0.9919
The probability that Julia will have no spelling mistakes on at least one of the pages is approximately 99.19%.
To determine the probability that Julia will have no spelling mistakes on at least one of the four pages she writes, we can first find the probability that she will make at least one spelling mistake on all four pages and then subtract this from 1.
The probability that there will be a spelling mistake on a page:
= 1 - 0.7 = 0.3.
Since the probability of a spelling mistake on each page is independent, we can multiply the probabilities for the four pages together.
The probability of at least one mistake on all four pages:
= 0.3 x 0.3 x 0.3 x 0.3 = 0.3⁴= 0.0081.
The probability that there will be no spelling mistakes on at least one page
= 1 - 0.0081 = 0.9919 or about 99.19%.
So, the probability is 99.19%.

OUTCOME 4: There is a 70% Chance that a student will pass a statistics course if I randomly choose a group of five students find the probability that exactly two will pass the course and explain how you derived your solutions
Answer:
The required probability is [tex]\frac{1323}{10000}[/tex]Step-by-step explanation:
It is given that The chance, that a student will pass the statistic course is [tex]\frac{70}{100}[/tex]
Hence, The chance that a student will fail in the statistic course is [tex]\frac{100 - 30}{100} = \frac{30}{100}[/tex]
Any 2 students from the total of 5 students can be choosen in [tex]^{5}C_2 = \frac{5!}{3! \times2!} = 10[/tex] ways.
Hence, the probability will be [tex]10\times [\frac{70}{100}] ^{2} \times[\frac{30}{100} ]^{3} = \frac{49\times27}{10000} = \frac{1323}{10000}[/tex]
Final answer:
The probability that exactly two students will pass the statistics course is approximately 30.87%.
Explanation:
To find the probability that exactly two students will pass the statistics course, we can use the binomial probability formula. The formula is:
P(X = k) = C(n, k) * p^k * (1 - p)^(n - k)
In this case, n = 5 (number of students), k = 2 (number of students passing), and p = 0.7 (probability of passing).
Plugging in these values, we get:
P(X = 2) = C(5, 2) * 0.7^2 * (1 - 0.7)^(5 - 2)
Calculating, we find that P(X = 2) ≈ 0.3087, or approximately 30.87%.

I can do this with Emma and Jacob or shopping in the store they notice to Cashiers are applying the discounts differently the cashier on the left is taking 20% off the total bill then subtracting $10 the cashier on the right is subtracting 10 first and then taking the 20% off the total who's getting the better deal
Answer: the person on the left
Step-by-step explanation:
by taking 20% off of the total cost first they are getting the better deal.
The customer gets a better deal from the cashier on the left. Explanation on determining the better deal between two cashiers based on how they apply discounts.
To determine who is getting the better deal, let's compare the total bill after discounts for both cashiers:
Cashier on the left: 20% off, then subtract $10
Cashier on the right: Subtract $10 first, then 20% off
Example Calculation:
If the total bill is $100:
Left cashier: $100 - 20%($100) = $80, then $80 - $10 = $70
Right cashier: $100 - $10 = $90, then 20%($90) = $18, so $90 - $18 = $72
In this scenario, the customer gets a better deal from the cashier on the left.

Find the length of an arc
made by an 80° central
angle in a circle with a
10 ft. radius.
I'm not an expert at this but the answer should be 13.9 or 14
Final answer:
The length of the arc made by an 80° central angle in a circle with a 10 ft. radius is approximately 13.96 ft.
Explanation:
In order to find the length of an arc made by an 80° central angle in a circle with a 10 ft. radius, we need to use the formula for the circumference of a circle. The formula for the circumference is C = 2πr, where C is the circumference and r is the radius. In this case, the angle is 80°, so we need to find the fraction of a full circle that the angle represents. Since a full circle is 360°, the fraction is 80/360 = 2/9. Therefore, the length of the arc is 2/9 times the circumference of the circle with a 10 ft. radius.
To find the circumference of a circle with radius 10 ft., we can use the formula C = 2πr. Plugging in the value of the radius, we get C = 2π(10) = 20π ft. Since the length of the arc is 2/9 times the circumference, the length of the arc is (2/9)(20π) ft. Simplifying, we get (40/9)π ft. This is approximately 13.96 ft. Therefore, the length of the arc made by an 80° central angle in a circle with a 10 ft. radius is approximately 13.96 ft.

Given:
Mr. Harris has 48 pencils and 30 notebooks.
To find the number of packages he can make with each package have same number of each item.
Solution:
Number of pencils = 48
Number of notebooks = 30
In order to find the number of packages he can make with each package have same number of each item, we will find the greatest common factor of the given numbers.
To find the G.C.F., we will list down the prime factors of each.
[tex]48=2\times 2\times 2\times 2\times 3[/tex]
[tex]30=2\times 3\times 5[/tex]
We find that the G.C.F. = [tex]2\times 3[/tex] = 6

What is the cross-section of a cone that is perpendicular to the base? Rectangle that is perpendicular to the base? Cylinder that is parallel to the base? Triangular Prism that is parallel to the base? (urgent now please answer)
Answer:
1. Triangle or trapezoid.
2. A line
3. Circular
4. Triangular.
Step-by-step explanation:
1. The cross-section of a cone that is perpendicular to the base either of a shape of a triangle or a trapezoidal shape.
If we make the cross-section along the diameter of the base circle then the cross-section will be a triangle and otherwise, it will be of trapezoidal shape.
2. The cross-section of a rectangle that is perpendicular to the base is line only because a rectangle is a two-dimensional shape and if we cut it perpendicularly to the base it will give a line.

the greatest of four consecutive even integers is 14 less than twice the smallest integer. what are the integers
The four consecutive even integers are 20, 22, 24, 26
Solution:
Let the four consecutive even integers are a , a + 2, a + 4, a + 6
Let "a" be the smallest integer and "a + 6" be the largest integer
To find: the four consecutive even integers
Given that the greatest of four consecutive even integers is 14 less than twice the smallest integer
largest integer = twice the smallest integer - 14
a + 6 = 2(a) - 14
a + 6 = 2a - 14
a - 2a = -14 - 6
-a = -20
a = 20
Thus the four consecutive even integers are:
a = 20
a + 2 = 20 + 2 = 22
a + 4 = 20 + 4 = 24
a + 6 = 20 + 6 = 26
Thus the four consecutive even integers are 20, 22, 24, 26
What is the period of the function?
Identify the period of a periodic function from its graph. π 2π 4π 8π
PLEASE HURRY
Answer:
4π
Step-by-step explanation:
Period is whenever a wave repeats itself. I highlighted the period.
The Period of the given function is 0 to 4π.
What is Period of Function?The time interval between two waves is known as a Period whereas a function that repeats its values at regular intervals or periods is known as a Periodic Function.
Here, graph starts from 0 and goes down. After π our graph starts increasing and acheive maximum at 3π and then start coming down to y = 0 at 4π.
It means that from 0 to 4π graph complete its one cycle and in the same trend it start repeating again.
Thus, the Period of the given function is 0 to 4π.

Mindy and Troy combined ate 9 pieces of cake. Mindy ate 3 pieces of cake and Troy at 1/4 of the whole cake. Find C, the total pieces of cake. Also include the equation
Answer:
The total pieces of cake are 24
Step-by-step explanation:
Linear equations
It's a relation between one or more variables and or numbers, connected with the equal sign. An example is 4x-5=7, or 2(x+y)=7-(x-y)
This problem can be easily solved without the use of equations, but we are required to.
We know Mindy and Troy combined ate 9 pieces of cake, we also know that Mindy ate 3 pieces of cake. It leaves 6 pieces to Troy. Since Troy ate 1/4 of the whole cake, then
[tex]\displaystyle \frac{1}{4}X=6[/tex]
Where X is the number of pieces of cake
Solving for X
[tex]X=(4)(6)=24\ pieces[/tex]
