1 answer:
Answer:
22/3 feet
Step-by-step explanation:
In Lixue's garden, the green pepper plants grew 5 inches in 3/4 month.
We need to find how many feet can they grow in one month.
Let 5 inches = 5 1/2 feet
It means,
The growth in 3/4 month = 5 inches = 11/2 feet
Growth in 1 month = feet
So, it will grow 22/3 feet in a month.

Step-by-step explanation:
Suppose pieces of chocolate pie served at a restaurant average 350 calories with a standard deviation of 20 calories. Calories have a Normal distribution due to inexact cutting of the pies. Which graph represents the proportion of pieces of pie that have more than 375 calories.
Answer: The z score is used to determine how many standard deviations that the raw score is above or below the mean. If the z score is positive then the raw score is above the mean and for a negative z score means the raw score is below the mean. The z score is given as:
Given that: μ = 350 calories, σ = 20 calories, x > 375
From the graph, The shaded area represents the proportion of pieces of pie that have more than 375 calories
From the normal distribution table, P(x > 375) = P(z > 1.25) = 1 - P(z < 1.25)
= 1 - 0.8944 = 0.1056 = 10.56%
