Step-by-step explanation:
The vertex is the extreme point of the curve. It lies on the vertical line that is the axis of symmetry.
The x-intercepts are where the graph crosses the x-axis. (They are symmetrically located about the axis of symmetry.)
The y-intercept is where the graph crosses the y-axis.
What is an example of a compound event??
Answer: Flipping a coin, or drawing a card suit (spades, hearts, clubs, or diamonds), either of those works.
Step-by-step explanation: A compound event is the combination of two or more simple events (with two or more outcomes). The probability of drawing a heart, replacing the card, then drawing a spade. In a compound event, the numerator ("number of times it can occur") will be greater than 1.

A distribution center makes deliveries to food stores on a weekly basis. On the average, 50 stores are served daily. A typical store places an order for 10,000 lb of various products. 4 store orders can be placed on a delivery truck. Trucks are loaded in 5 hours. The distribution center operates an 8 hour shift. How many truck doors are needed?
Answer:
3 doors needed
Step-by-step explanation:
The computation of the no of trucks doors that are needed is shown below:
= serve daily ÷ no of store orders ÷ no of store orders
= 50 ÷ 4 ÷ 4
= 3 doors needed
First we divided the serve daily from the no of store orders and then the value that comes so it would be divided by no of store orders again so that the no of truck doors could come

According to the U.S. Department of Agriculture, the average American consumed 54.3 pounds (ap- proximately seven gallons) of salad and cooking oils in 2008 (www.ers.usda.gov/data/foodconsumption). Suppose that the current distribution of salad and cooking oil consumption is approximately normally distributed with a mean of 54.3 pounds and a standard deviation of 14.5 pounds.
1. What percentage of Americans' annual salad and cooking oil consumption is less than 10 pounds?
2. What percentage of Americans' annual salad and cooking oil consumption is between 35 and 60?
3. What percentage of Americans' annual salad and cooking oil consumption is more than 95 pounds?
Answer:
a) 0.11%
b) 55.99%
c) 0.25%
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score 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 p-value, we get the probability that the value of the measure is greater than X.
Normally distributed with a mean of 54.3 pounds and a standard deviation of 14.5 pounds.
This means that [tex]\mu = 54.3, \sigma = 14.5[/tex]
1. What percentage of Americans' annual salad and cooking oil consumption is less than 10 pounds?
The proportion is the pvalue of Z when X = 10. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{10 - 54.3}{14.5}[/tex]
[tex]Z = -3.06[/tex]
[tex]Z = -3.06[/tex] has a pvalue of 0.0011
0.0011*100% = 0.11%.
2. What percentage of Americans' annual salad and cooking oil consumption is between 35 and 60?
The proportion is the value of Z when X = 60 subtracted by the pvalue of Z when X = 35.
X = 60
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{60 - 54.3}{14.5}[/tex]
[tex]Z = 0.39[/tex]
[tex]Z = 0.39[/tex] has a pvalue of 0.6517
X = 35
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{35 - 54.3}{14.5}[/tex]
[tex]Z = -1.33[/tex]
[tex]Z = -1.33[/tex] has a pvalue of 0.0918
0.6517 - 0.0918 = 0.5599
0.5599*100% = 55.99%
3. What percentage of Americans' annual salad and cooking oil consumption is more than 95 pounds?
The proportion is 1 subtracted by the pvalue of Z when X = 95.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{95 - 54.3}{14.5}[/tex]
[tex]Z = 2.81[/tex]
[tex]Z = 2.81[/tex] has a pvalue of 0.9975
1 - 0.9975 = 0.0025
0.0025*100% = 0.25%
(1.) 0.11% of Americans annual salad and cooking oil consumption is less than 10 pounds.
(2) 55.99% of Americans annual salad and cooking oil consumption is between 35 and 60.
(3).0.25% Americans annual salad and cooking oil consumption is more than 95 pounds.
Given, the average american consumed 54.3 pounds of salad and cooking oils in 2008.
the mean of salad and cooking oil consumption is approximately 54.3 pounds and a standard deviation of 14.5 pounds.
The formula for calculating a z-score is,
[tex]z = \dfrac{(X-\mu)}{\sigma}[/tex]
where [tex]X[/tex] is the raw score, μ is the population mean, and σ is the population standard deviation.
The value of the z-score tells you how many standard deviations you are away from the mean. If a z-score is equal to 0, it is on the mean. A positive z-score indicates the raw score is higher than the mean average.
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 p-value, we get the probability that the value of the measure is greater than X.
1. percentage of Americans annual salad and cooking oil consumption is less than 10 pounds.
Here X=10
[tex]z=\dfrac{10-54.3}{14.5}[/tex]
[tex]z=-3.06[/tex]
Since [tex]z=-3.06[/tex] has a p value of 0.0011,so
[tex]0.0011\times100\%=0.11\%[/tex]
2.percentage of Americans' annual salad and cooking oil consumption is between 35 and 60.
the proportion is the value of Z when X = 60 subtracted by the p value of Z when X = 35.
At X=60,
[tex]z=\dfrac{60-54.3}{14.5}[/tex]
[tex]z=0.39[/tex]
0.39 has a p value of 0.6517.
At X=60,
[tex]z=\dfrac{35-54.3}{14.5} \\[/tex]
[tex]z=-1.33[/tex]
-1.33 has a p value of 0.0918.
Now,[tex]0.6517 - 0.0918 = 0.5599[/tex]
[tex]0.5599\times100\% = 55.99\%[/tex]
3. percentage of Americans' annual salad and cooking oil consumption is more than 95 pounds.
Here, The proportion is 1 subtracted by the p value of Z when X = 95.
[tex]z=\dfrac{95-54.3}{14.5}[/tex]
[tex]z=2.81[/tex]
[tex]z=2.81[/tex] has a p value of 0.9975.
So, [tex]1 - 0.9975 = 0.0025[/tex].
Now, [tex]0.0025\times100\% = 0.25\%[/tex].
Hence the correct percentage is 0.11%,55.99% and 0.25% respectively.

Hello help me out thank you !
Answer:
1130.4
Step-by-step explanation:
The volume of a cylinder is πr^2h, where r is the radius and h is the height.
We are given the height, 10m.
The diameter is 2m more than the height, so 2+10=12m.
The radius is half the diameter, so 12m/2=6m.
Use r=6 and h=10 in the formula to get the volume
π6^2*10≈1130.4
