Answer:
83
Step-by-step explanation:
Remember that the perimeter of a rectangle is two times the width plus two times the length. In other words:
2W + 2L = P
We know that the perimeter is 290 and the width is 62. We can plug these into the equation and solve for L.
2(62) + 2L = 290
124 + 2L = 290
Subtract 124 from both sides.
2L = 166
Divide both sides by 2.
L = 83
So now we know that the length is 83 feet.

Answer:
A.99.7%
Step-by-step explanation:
We are given;
- Mean of a distribution, μ as 0.68 ounce
- Standard deviation, σ as 0.02 ounce
- The range values of X between 0.62 ounce and 0.74 ounce
We are required to calculate the percentage of the weight to be between 0.62 ounce and 0.74 ounce
Step 1: Calculate the Z-score
To get the Z-score we use the formula;
Z-score = (x-μ)/σ
Therefore, when x = 0.62
Then z score = (0.62 - 0.68 ) ÷ 0.02
= -3
When, x = 0.74
Then, Z score = (0.74 - 0.68) ÷ 0.02
= 3
Step 2: we use the Z-score table or the empirical rule
Using the Z-score table;
P(-3 < z < 3) = 99.7%.
Therefore; the percentage of mice that weigh between 0.62 ounce and 0.74 ounce is 99.7%.
