Distribute
3k-18=15
Get k by itself, add 18 to both sides
3k=33
Divide by 3 to both sides to make k by itself
k=11
Express 0.9534 as a fraction
<span>0.9534 × 10 × 10 × 10 × 10 = 9534
</span><span>1 × 10 × 10 × 10 × 10 = 10000
</span>9534/10000
Divide by GCF:-
GCF = 2
9534 ÷ 2 = 4767
1000 ÷ 2 = 500
4767/500
^^^Improper fraction
Convert to mixed number:-
4767 ÷ 500 = <span>9.534
500 × 9 = 4500</span>
<span>4767 - 4500 = 267</span>
<span>9 = whole number</span>
<span>267 = </span>numerator
<span>500 = </span>denominator
<span>
9 267/500
0.9534 = 9537/10000 = 4767/1000 = 9 267/500 </span><span />
Hey there!
-1.3n = 7.8
First, you have to DIVIDE both sides by -1.3
-1.3n / -1.3 = 7.8 / -1.3
Cancel out: -1.3 / -1.3 because it gives you the value of 1
Keep: 7.8 / -1.3 because it gives us the value of n
7.8 ÷ -1.3 = -6
Thus, n = -6 ✅
Good luck on your assignment and enjoy your day!

Answer:
C. The coefficient of variation is a measure of relative dispersion that expresses the standard deviation as a percentage of the mean, for any data on a ratio scale and an interval scale
Step-by-step explanation:
Th Coefficient of Variance is a measure of dispersion that can be calculated using the formula:

Where
is the Standard Deviation
and
is the sample mean
From the formula written above, it is shown that the Coefficient of Variation expresses the Standard Deviation as a percentage of the mean.
Coefficient of variation can be used to compare positive as well as negative data on the ratio and interval scale, it is not only used for positive data.
The Interquartile Range is not a measure of central tendency, it is a measure of dispersion.
