Answer:
The z-score for this length is of 1.27.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean
and standard deviation
, the z-score 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 p-value, we get the probability that the value of the measure is greater than X.
One-year-old flounder:
Mean of 127 with standard deviation of 22, which means that 
Anna caught a one-year-old flounder that was 155 millimeters in length. What is the z-score for this length
This is Z when X = 155. So



The z-score for this length is of 1.27.
Answer: estimate 7
exact: 6 7/15
Step-by-step explanation: for the estimate round 3 4/5 to 4 and 2 2/3 to 3 and 4 + 3 = 7
for the exact number convert 3 4/5 to 3 12/15
and convert 2 2/3 to 2 10 /15
then add 3 + 2 = 5
and 12/15 + 10/15 = 22/15
convert 22/15 to a mixed number which is 1 7/15
then 5 + 1 7/15
answer 6 7/15

Answer:
77 inches
Step-by-step explanation:
sector formula = x°/360° × πr^2
=77°/360°×22/7×10.7×10.7
=76.96 in
As it is asked the nearest tenth it's 77 inches.
