Answer:
The radius is 6!
Step-by-step explanation:
We know that both OA and OB lay on the circle, and O is the center.
In this equation you are trying to find O. We also know that OA = OB.
2x + 9 = 27 - x
2x = 18 - x (subtracted 9 from each side)
3x = 18 (added 1x to each side)
x = 6 (divided both sides by 3, to find x)

Step-by-step explanation:
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?
Answers
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.

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?
Answers
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

obtuse scalene triangle
Step-by-step explanation:
All angles in a triangle add up to 180°.
[tex]3x-5+x+10+x=180[/tex]
[tex]5x+5=180[/tex]
[tex]5x=175[/tex]
[tex]x=35[/tex]
So, x=35.
When we plug in x to each angle, we see that the 3x-5 angle is above 90°, and all of the angles are different. So, this is an obtuse scalene triangle.

A. 3s + s less than or equal to 9
B. 3s greater than or equal to 9
C.3s + s greater than or equal to 9
D.s less than or equal to
Answers
Answer:
The answer is C as money needed to spend on lunch is 3times on snacks so if we let money on snacks as s then lunch will be 3s.
Step-by-step explanation:
And the total money he has is $9 so
3s+s = 9
The inequality will be 3s + s greater than or equal to 9. The correct option is C.
What is inequality?The relation between two expressions that are not equal, employing a sign such as ≠ ‘not equal to, > ‘greater than, or < ‘less than.
It is given that Crystal has $9 to spend on lunch and an afternoon snack. If lunch costs three times as much as the snack.
The answer is C as the money needed to spend on lunch is 3 times on snacks if we let money on snacks as s then lunch will be 3s. And the total money he has is $9.
3s+s = 9
Therefore, the inequality will be 3s + s greater than or equal to 9. The correct option is C.

Step-by-step explanation:
In the picture shown in the question, the line segment SQ would be considered the angle bisector. This is because it is dividing the interior angles' opposite side into two line segments. Hence the line segments PQ and QR. The angle bisector divides the opposite side into line segments that are proportional to the other two sides of the triangle which in this case can be seen by the top left indication in the picture stating that PQ and QR are the same.
