SECTION B

Answer: The median value of data set B is -5.5, which is less than the median value of 3.1 in dataset A.

Step-by-step explanation:

Order the dataset from least to greatest:

-38 → -13 → -9 → -2 → 14 → 28

Then find the values that lies in the middle:

-38 → -13 → -9 → -2 → 14 → 28

Since there are 2 values, find the average of those 2 values:

$\frac{-9+(-2)}{2} =\frac{-11}{2} =-5.5$

The median value = -5.5.

The median value of data set B is -5.5, which is less than the median value of 3.1 in dataset A.

Answer:

Question 6

$\left(5a+2\right)\left(a+4\right)=\:5a^2+22a+8$

Question 7

The width is 2x.

Step-by-step explanation:

Question 6)

Expand

$(5a+2)(a+4)$

solving to the expand

$(5a+2)(a+4)$

$\mathrm{Apply\:FOIL\:method}:\quad \left(a+b\right)\left(c+d\right)=ac+ad+bc+bd$

$a=5a,\:b=2,\:c=a,\:d=4$

so the expression becomes

$=5aa+5a\cdot \:4+2a+2\cdot \:4$

$=5aa+5\cdot \:4a+2a+2\cdot \:4$

$=5a^2+20a+2a+8$

adding similar elements: 20a+2a=22a

$=5a^2+22a+8$

Hence,

$\left(5a+2\right)\left(a+4\right)=\:5a^2+22a+8$

Question 7)

Given

$A\:=\:8x^2$

$l=4x$

Using the formula

width = Area/Length

$=\:\frac{8x^2}{4x}$

$=2x$ ∵ $\mathrm{Divide\:the\:numbers:}\:\frac{8}{4}=2$

Therefore, the width is 2x.
