In order for the sum to be a positive integer, the sign of the other integer needs to be positive and the value needs to be greater than -5. If it wasn't greater than -5 or if it was negative then the sum of them would be a negative integer.
Answer:
120 ft
Step-by-step explanation:
First, you should decipher how many minutes have passed by 10:57-11:05 AM. When you count up to 11:05 AM starting from 10:57 AM, you should get 8, meaning 8 minutes have passed by.
After that, you should multiply the minutes by how many feet Shana can dive per minute. 15 (feet per minute) multiplied by 8 (minutes) equals 120.
In 8 minutes her depth will 120 ft.
Given:
mean, μ = 11 lb
Std. deviation, σ = 2.1
Let x = the weight that separates the top 5% of the crop.
The z-score is
z = (x - μ)/σ
= (x - 11)/2.1
From standard z-table for normal distribution,
P(z=1.645) = 0.95
Therefore
(x - 11)/2.1 = 1.645
x - 11 = 1.645/2.1 = 0.7833
x = 11.783
Answer: 11.8 lb (nearest tenth)
