120 + 5d = 445 <==
** parts + labor = 445
p = 120
labor = 5 hrs * d...where d is cost per hr

Answer:
133pi
98% sure this is right
circumference in pi form is the radius time 2 and then put pi after it
Step-by-step explanation:
The answer would be 4/85
1. 2/5 ÷ 8 * 2 + 1 over 2
2. 2/5 ÷ 16 + 1 over 2
3. 2/5 ÷ 17/2
4. 2/5 * 2/17
5. 2 * 2 over 5 * 17
6. 4 over 5 * 17
7. finally 4/85
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%.
