Answer:
40%
Step-by-step explanation:
2/5 can be converted to 40/100 by multiplying the numerator and denominator by 20.
40/100 is equivalent to 40%.
Answer:
B. 5
Step-by-step explanation:
Step 1: Rewrite the equation a bit
![\frac{7^\frac{3}{4}}{7^\frac{x}{8}}=\sqrt[8]{7}\\7^\frac{3}{4}^-^\frac{x}{8}=7^\frac{1}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B7%5E%5Cfrac%7B3%7D%7B4%7D%7D%7B7%5E%5Cfrac%7Bx%7D%7B8%7D%7D%3D%5Csqrt%5B8%5D%7B7%7D%5C%5C7%5E%5Cfrac%7B3%7D%7B4%7D%5E-%5E%5Cfrac%7Bx%7D%7B8%7D%3D7%5E%5Cfrac%7B1%7D%7B8%7D)
Step 2: Place a logarithm base 7 on both sides

Step 3: Solve for x

Neat exponent question :)
Answer:
2 and 96 (lowest and highest #s far from any other #s listed
<h3>
Answer: C) increase from 45 degrees to 50 degrees</h3>
===============================================
Explanation:
Let's calculate the angle B based off the arcs CDF and GHJ
B = (far arc - near arc)/2
B = (arc CDF - arc GHJ)/2
B = (130 - 40)/2
B = 90/2
B = 45
----------
Now let's change GHJ to 30 degrees, while keeping the other arc the same.
B = (far arc - near arc)/2
B = (arc CDF - arc GHJ)/2
B = (130 - 30)/2
B = 100/2
B = 50
Angle B has increased from 45 degrees to 50 degrees.
Answer:
The measure of variability should be used.
Step-by-step explanation:
It is provided that Rickie played eight rounds of miniature golf in June and eight rounds of miniature golf in July. He recorded the cores for each round.
Now to determine in which month Rickie's score varied the most the measure of variability would be used and not measure of center.
This is because:
The Measures of Central tendency is a distinct value that describe a data set by recognizing the central location within that data set. The measures of central tendency are every so often are known as measures of central location. They are also known as summary statistics.
Whereas the measure of variability is used to determine the amount of variability in the data set. They represent how far the observations are from the center of the data set.
Thus, to answer his mother's question, the measure of variability should be used.
