Answer: I think the answer is 8hrs and 30 minuets
Answer:
v = 0.58
Step-by-step explanation:
-22 - 7v = -3(8v + 4)
Expand -3(8v + 4)
3 * 8v - 3 * 4
Simplify -3 * 8v -3 * 4
= -24v - 12
-22 - 7v = -24v - 12
Add 22 to both sides
-7v = -24v +10
Add 24v to both sides
17v = 10



Answer:
Weights of at least 340.1 are in the highest 20%.
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean
and standard deviation
, the zscore of a measure X is given by:

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.
In this problem, we have that:

a. Highest 20 percent
At least X
100-20 = 80
So X is the 80th percentile, which is X when Z has a pvalue of 0.8. So X when Z = 0.842.




Weights of at least 340.1 are in the highest 20%.
Answer:
15 inches
Step-by-step explanation:
The area of a circle is pi r^2. We basically have to work backwards. I divided it fist by 3.14 which is the value of pi. I got 225.127, but I rounded it to 225. I found the square root of this which is 15. If we check the work. 15^2 is 225, and 225 times pi is 706.9.
