Answer the questions about the cone. V= 1/3 BH
What is the radius of a cone?
3,4,6,8 ft
What is the area of the base of the cone?
6,9,8,16 pi ft squared
What is the volume of the cone?
16,24,48,72 pi ft cubed
Answers
Answers the answer for question one is 3 , for question number two the answer is 9 and the answer for the last question is 24
Step-by-step explanation:
The radius of the cone is 3ft
The base area of the cone is 28.26ft²
The volume of the given cone is 75.36ft³
The formula for calculating the volume of a cone is expressed as:
[tex]V = \frac{1}{3} \pi r^2 h[/tex]
r is the base radius
h is the height of the cone
V is the volume of the cone
From the diagram, the base diameter is 6 ft
Base radius = 6/2 = 3ft
The area of the base of the cone is [tex]\pi r^2 h[/tex]
Base area = [tex]3.14 \times 3^2\ = 28.26ft^2[/tex]
Get the required volume of the cone
Volume = Base area/3
Volume = [tex]\frac{1}{3} \times 28.26 \times 8 = 75.36ft^3[/tex]
Hence the volume of the given cone is 75.36ft³

A company makes car batteries and claims 80% of its ABC batteries are good for 70 months or longer. Assume that this claim is true. Let p ˆ be the proportion in a sample of 100 such ABC batteries. What is the probability that this sample proportion is within 0.05 of the population proportion.
Answers
Answer:
78.88% probability that this sample proportion is within 0.05 of the population proportion
Step-by-step explanation:
We need to understand the normal probability distribution and the central limit theorem to solve this question.
Normal probability distribution
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For proportion p in a sample of size n, we have that [tex]\mu = p, s = \sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In this question:
[tex]p = 0.8, n = 100[/tex]
So
[tex]\mu = 0.8, s = \sqrt{\frac{0.8*0.2}{100}} = 0.04[/tex]
What is the probability that this sample proportion is within 0.05 of the population proportion.
This is the pvalue of Z when X = 0.8 + 0.05 = 0.85 subtracted by the pvalue of Z when X = 0.8 - 0.05 = 0.75.
X = 0.85
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{0.85 - 0.8}{0.04}[/tex]
[tex]Z = 1.25[/tex]
[tex]Z = 1.25[/tex] has a pvalue of 0.8944.
X = 0.75
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{0.75 - 0.8}{0.04}[/tex]
[tex]Z = -1.25[/tex]
[tex]Z = -1.25[/tex] has a pvalue of 0.1056.
0.8944 - 0.1056 = 0.7888
78.88% probability that this sample proportion is within 0.05 of the population proportion

Area of a square is:
A = s²
Take derivative of both sides with respect to time:
dA/dt = 2s ds/dt
Given that dA/dt = 6 m²/s and s = 9 m:
6 m²/s = 2 (9 m) ds/dt
ds/dt = ⅓ m/s
The Formula of the area of a square: A = bh or A = s^2
Solution:
~Take derivative of both sides

the stained glass below shows bilateral symmetry. The two overlapping squares are congruent. What is the area of the window?
Answers
Answer:
116.82 square inches
Step-by-step explanation:
The overall shape is that of a 10-inch square with four triangles attached. Each of those is an isosceles right triangle with leg lengths of 2.9 inches.
The area of the four triangles is ...
total triangle area = 4(1/2)(2.9 in)(2.9 in) = 16.82 in²
The area of the 10-inch square is ...
square area = (10 in)² = 100 in²
Then the total window area is ...
window area = 16.82 in² +100 in²
window area = 116.82 in²

Stacy uses a spinner with six equal sections numbered 2, 2, 3, 4, 5, and 6 to play a game. Stacy spins the pointer 120 times and records the results. The pointer lands 30 times on a section numbered 2, 19 times on 3, 25 times on 4, 29 times on 5, and 17 times on 6.
Write a probability model for this experiment, and use the probability model to predict how many times Stacy would spin a 6 if she spun 50 times. Give the probabilities as decimals, rounded to 2 decimal places
Answers
Answer:
Hence, Stacy will spin 6, 8.33 times out of her n = 50 attempts.
Step-by-step explanation:
Let us consider a success to get a 6. In this case, note that the probability of having a 6 in one spin is 1/6. We can consider the number of 6's in 50 spins to be a binomial random variable. Then, let X to be the number of trials we get a 6 out of 50 trials. Then, we have the following model.
We will estimate the number of times that she spins a 6 as the expected value of this random variable.
Recall that if we have X as a binomial random variable of n trials with a probability of success of p, then it's expected value is np.
Then , in this case, with n=50 and p=1/6 we expect to have number of times of having a 6, which is 8.33.

2. is D $411.25
Jimmy's Total Minimum Credit Card Payment must be equal to $71.54 if he is to clear his debt over the next 12 months.
What is Minimum Credit Card Payment (MCC)?In order for a credit issuer to give an applicant a card, there is a minimum amount that must be deposited into and remain in such a bank account every month. This is what is called a minimum credit card payment.
To calculate Jimmy's MCCP across all cards, we must use the formula:
(APR * Days of Billing Cycle * balance)/365
So for A:
((563 * 30 * 16)/365)/100 = $7.40
For B:
((2,525 * 30 * 21)/365) / 100 = $43.52
For C:
((972 * 30 * 19)/365) / 100 = $15.18
For D:
((389 * 30 * 17)/365) / 100 = $5.44
To get Jimmy's total Minimum Credit Card Payment, we say:
7.40 + 43.52 + 15.18 + 5.44 = $ 71.54

at the dade county fair, the williams family bought 6 burgers and 4 gatorades for $14.10. the jackson family bought 3 burgers and 4 gatorades for $9.15.find the price of a burger and the price of a gatorade sn: i need help like really fast
Answers
Answer:
The cost of a burger is $1.65 and the cost of a gatorade is $1.05.
Step-by-step explanation:
We can solve this question using a system of equations.
I am going to say that:
x is the price of a burger.
y is the price of a gatorade.
6 burgers and 4 gatorades for $14.10
This means that [tex]6x + 4y = 14.10[/tex]
3 burgers and 4 gatorades for $9.15.
This means that [tex]3x + 4y = 9.15[/tex]
Will write 4y as a function of x.
[tex]4y = 9.15 - 3x[/tex]
Replacing in the first equation:
[tex]6x + 4y = 14.10[/tex]
[tex]6x + 9.15 - 3x = 14.10[/tex]
[tex]3x = 4.95[/tex]
[tex]x = \frac{4.95}{3}[/tex]
[tex]x = 1.65[/tex]
And
[tex]4y = 9.15 - 3x[/tex]
[tex]4y = 9.15 - 3*1.65[/tex]
[tex]4y = 4.2[/tex]
[tex]y = \frac{4.2}{4}[/tex]
[tex]y = 1.05[/tex]
The cost of a burger is $1.65 and the cost of a gatorade is $1.05.
