It is the bottom row
Answer:
the distancev from 7±9y±11=0 is 0.97
AC=28cm BC=9cm, because AC=2xAB and BC=AC/2
The standard deviation of the data set is 19.3
<h3>How to find the standard deviation of the data set?</h3>
The dataset is given as:
82, 94, 105, 68, 57
Calculate the mean using
Mean = Sum/Count
So, we have
Mean = (82 + 94 + 105 + 68 + 57)/5
Evaluate
Mean = 81.2
The standard deviation is then calculated as:

So, we have:
SD = √[(82 - 81.2)^2 + (94 - 81.2)^2 + (105 - 81.2)^2 + (68 - 81.2)^2 + (57 - 81.2)^2)/5 - 1]
This gives:
SD = √[1490.8/4]
So, we have:
SD = 19.3
Hence, the standard deviation of the data set is 19.3

Answer:
A=45
Step-by-step explanation:
If a rectangle has a width of 3 inches and its length is 5 times its width, the area of the rectangle is 45 square inches.
Width = 3 inches
Length = 5 x width ( 3 ) = 15
Formula: A=wl
A=wl=15·3=45
