Answer:
15.74% of women are between 65.5 inches and 68.5 inches.
Step-by-step explanation:
Problems of normally distributed samples can be solved using the z-score formula.
In a set with mean
and standard deviation
, the zscore 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 pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:

What percentage of women are between 65.5 inches and 68.5 inches?
This percentage is the pvalue of Z when X = 68.5 subtracted by the pvalue of Z when X = 65.5.
X = 68.5



has a pvalue of 0.9987
X = 65.5



has a pvalue of 0.8413
So 0.9987 - 0.8413 = 0.1574 = 15.74% of women are between 65.5 inches and 68.5 inches.
The result of diving 107 by 10⁻³ is (E) 107,000.

What do we mean by division?</h3>
- The division is one of the four basic operations of arithmetic, which are the methods by which numbers are combined to form new numbers.
- Addition, subtraction, and multiplication are the other operations.
- At the most basic level, the division of two natural numbers is the process of calculating the number of times one number is contained within another.
- For example, if 20 apples are distributed evenly among four people, each receives five apples (see picture).
So, we know that 10⁻³ is 0.001.
- Now, 107/0.001 = 107,000.
Therefore, the result of diving 107 by 10⁻³ is (E) 107,000.

Answer:
Larger fraction = 24/7
Step-by-step explanation:
Given that:
Smaller fraction = 8/3
Larger fraction = ?
Let the larger fraction is x/y then according to the statement:
8/3 / x/y = 7/9
Rule: When there is a fraction in the denominator of a fraction, the lower fraction is reversed and multiplied with the upper one.
So, according to rule:
8/3 * y/x = 7/9
8y/ 3x = 7/9
Now multiplying both sides by 3/8 we get
8y/ 3x * 3/8 = 7/9 *3/8
After cancellation:
y/x = 21/ 72
By reducing it to lowest form (dividing both by 3)
We ge:
y / x = 7/ 24
This means y= 7
x = 24
So the larger fraction will become: x/y =24/7
Smaller fraction / Larger fraction = 7/9
8/3 / 24/7 = 7/9
Applying Rule:
8/3 * 7/24 = 7/9
56/ 72 = 7/9
Reducing it to lowest fraction: (dividing both by 8)
7/9 = 7/9
Hence proved
I hope it will help you!
