Answer:
10
Step-by-step explanation:
Yesterday, Priya successfully made 6 free throws.
Today, she made 75% as many as yesterday.
We are asked to calculate the number of successful free throws that Priya made today.
So, the number will be .
Since it is the number of successful free throws, so it will be 10 throws. ( Answer )
Using the normal distribution, it is found that the probability is 0.16.
<h3>Normal Probability Distribution</h3>In a normal distribution with mean and standard deviation
, the z-score of a measure X is given by:
- It 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, which is the percentile of X.
In this problem, the mean and the standard deviation are given by, respectively, .
The proportion of students between 45 and 67 inches is the p-value of Z when <u>X = 67 subtracted by the p-value of Z when X = 45</u>, hence:
X = 67:
Z = -1
Z = -1 has a p-value of 0.16.
X = 45:
Z = -8.3
Z = -8.3 has a p-value of 0.
0.16 - 0 = 0.16
The probability is 0.16.

Answer:
278.63 square inches
Step-by-step explanation:
Gina needs to cut two types of rectangles.
Dimensions of one rectangle is given as,
Width = 12 inches
Length = =
inches
So, the area of this rectangular paper will be
Area = width × length = = 171 inches²
Dimensions of the other rectangular paper has been given as
Width = =
inches
Length = =
inches
So, the area of this rectangle will be
Area = width × length = = 107.63 inches²
Thus the total area she need to cut = 171 + 107.63 = 278.63 square inches.
