Answer:
42
Step-by-step explanation:
Divide it into 2 parts: 1*12 and (12*5)/2
1*12 = 12
(12*5)/2 = 60/2 = 30

A local animal rescue has 20 people that help foster pets while they are
waiting on finding their homes. They expect to gain two additional people
willing to foster animals each month. The amount of animals in need of
homes in the community is currently 10 and growing at a rate of 15% per
month. When will the amount of homeless pets surpass the amount of foster
homes available?
A) Write the two functions that represent this situation.
B) Create a table of values for x=0 to x=13.
C) Approximate the solution(s). Why is this the approximate solution?
D) Using graph paper (and the table of values), sketch the situation to
show the exact solution.
Answer:
A) Let f(x) represent the number of foster homes available after x months, and let g(x) represent the number of homeless pets after x months.
f(x) = 20 + 2x (since 2 additional people are expected to foster each month)
g(x) = 10(1.15)^x (since the number of homeless pets is growing at a rate of 15% per month)
PLEASE HELP!!!!!!A set of data includes 98 data points ranging from 0 – 160. If the data is split into classes with a range of 10 (1 – 10, 11 – 20, etc), and there are no values that fall in the class 81 – 90, what can you say about the data?
1 The mean of the data will not be between 81 – 90.
2 All the data lies below 80.
3 The relative frequency of the class 81 – 90 is 0.
4 The median could be in the range 81 – 90.
Johnny had $8.25 in quarters. He went to the laundromat and spent all of his quarters doing laundry. Which equation describes how many quarters Johnny had, where n is the number of quarters Johnny had?
8.25 / 25 = n
The "/" is division.
Answer:
n+8.25/.25
or
n=825/25

Find the radius of the circle.
Circumference = 18.84 yd
a. 3 yd
b. 59.16 yd
c. 6 yd
d. 118.32 yd
what's the answer??
Answer:
A. 3yd
Step-by-step explanation:
There are two formulas that can be used for the circumference of a circle:
c = πd and c = 2πr
Since we want to solve for the radius, let's use c = 2πr
The circumference, 'c', is 18.84 inches
Since 'π' is an irrational number, we use its approximation of 3.14
We are trying to solve for 'r', which is the radius
The circumference, 'c', is 18.84 inches
Since 'π' is an irrational number, we use its approximation of 3.14
We are trying to solve for 'r', which is the radius
Plugging in, we get:
18.84 = 2(3.14)r
Since 'π' is an irrational number, we use its approximation of 3.14
Notice there are the same amount of decimal places (two!) in the answer as the combined amount of spaces in the numbers being multiplied!
18.84 = 6.28r
The goal is to isolate and solve for 'r', which is the radius
18.84/6.28 = 3
So we get "3 = r", which means the radius is 3 inches!

A local newspaper was wondering if its average reader lived more than 25 miles from its headquarters. The newspaper surveyed its readers and received 10 responses. Using the results from the current survey and several previous surveys, the newspaper has decided to assume that the population standard deviation for the distance its readers live from its headquarters is 13.2 miles. The local newspaper conducts a one-mean hypothesis at the 5% significance level, to test if the average distance a reader lives from the newspaper's headquarters is greater than 25 miles.
(a) H0:μ=25; Ha:μ>25, which is a right-tailed test.
(b) z0=0.22, p-value is = 0.41.
(c) Which of the following are appropriate conclusions for this hypothesis test? Select all that apply.
We reject H0.
We fail to reject H0.
At the 5% significance level, the data provide sufficient evidence to conclude that the average distance a reader lives from the newspaper's headquarters is greater than 25 miles.
At the 5% significance level, the data do not provide sufficient evidence to conclude that the average distance a reader lives from the newspaper's headquarters is greater than 25 miles.
Answer:
Step-by-step explanation:
From the information given,
For null hypothesis,
H0:μ=25
For alternative hypothesis,
Ha:μ > 25
It is a right-tailed test due to the inequality sign in the alternative hypothesis.
The decision rule would be to reject the null hypothesis if the significance level is greater than the p value.
Since the significance level, 0.05 is < p-value, 0.41, then we fail to reject H0. Therefore,
At the 5% significance level, the data do not provide sufficient evidence to conclude that the average distance a reader lives from the newspaper's headquarters is greater than 25 miles.

Answer:
A = plane
B = whale
C = sunken ship
Step-by-step explanation:
The given vertical number line is modelling the positions of objects and animals in relation to sea level.
Sea level is the average height of the surface of the world's oceans, which we use as a reference point to measure the elevation and depth of land and water features on Earth.
From inspection of the given number line:
Position A is above sea level.Position B is just below sea level.Position C is the furthest below sea level.We have been told that a plane is flying at 8,500 feet above sea level. Therefore, as position A is the only position above sea level, A = plane.
We have been told that a sunken ship is resting at 3,000 feet below sea level, and that directly above the ship, a whale is swimming 1,960 feet below sea level. Therefore, the whale is above the ship. As position B is above position C, this means that B = whale and C = sunken ship.

Answer:
answer is 3/5
Step-by-step explanation:
Use the Midpoint Rule with \(n=5\) to estimate the volume obtained by rotating about the y-axis the region under the curve \(y=\sqrt{1+x^3}\), \(0\leq x\leq 1\).
To estimate the volume using the Midpoint Rule with \(\displaystyle n=5\), we need to divide the interval \(\displaystyle 0\leq x\leq 1\) into \(\displaystyle n\) subintervals of equal width. Since \(\displaystyle n=5\), each subinterval will have a width of \(\displaystyle \Delta x=\frac{1-0}{5}=\frac{1}{5}\).
Now, let's calculate the volume using the Midpoint Rule. The formula for the volume obtained by rotating about the y-axis is:
\(\displaystyle V\approx 2\pi \sum _{i=1}^{n}y_{i}\Delta x\)
where \(\displaystyle y_{i}\) represents the value of the function \(\displaystyle y=\sqrt{1+x^{3}}\) evaluated at the midpoint of each subinterval.
First, let's find the midpoints of the subintervals. Since the width of each subinterval is \(\displaystyle \Delta x=\frac{1}{5}\), the midpoint of the \(\displaystyle i\)-th subinterval is given by:
\(\displaystyle x_{i}=\frac{\Delta x}{2}+\left( i-\frac{1}{2}\right) \Delta x=\frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\)
Substituting \(\displaystyle x_{i}\) into the function \(\displaystyle y=\sqrt{1+x^{3}}\), we obtain:
\(\displaystyle y_{i}=\sqrt{1+\left( \frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\right) ^{3}}\)
Now, we can calculate the approximate volume using the Midpoint Rule:
\(\displaystyle V\approx 2\pi \sum _{i=1}^{5}y_{i}\Delta x\)
Substituting the values of \(\displaystyle y_{i}\) and \(\displaystyle \Delta x\) into the formula, we can evaluate the sum and compute the estimated volume.
