Pl help i will mark Brainlest And hurry i'm on a time limit

Ben simplified this expression.

(StartFraction 2 x Superscript negative 4 Baseline y Superscript 7 Baseline Over 3 x cubed y squared EndFraction) cubed

1. (StartFraction 2 y Superscript 5 Baseline Over 3 x Superscript 7 Baseline EndFraction) cubed

2. StartFraction 2 y Superscript 15 Baseline Over 3 x Superscript 21 Baseline EndFraction

Analyze Ben’s work. Did he simplify the expression correctly? If not, what was his mistake?

A:Yes, he is correct.

B:No, he needed to add the exponents of powers of the same base in the first step.

C:No, he needed to apply the exponent to all factors in the product in the second step.

D:No, he needed to simplify further by subtracting the exponents of the powers.

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13

see below

step-by-step explanation:

7.   there are 10 data points in the set.   the middle point is between 5 and 6.   the middle point in the top half is 8   and the middle point in the bottom half is 3. to find the iqr , take point 8 and subtract point 3

mid term   point 8 = 100   point 3 = 88

iqr = 100-88 = 12

final   point 8 = 93   point 3 = 78

iqr = 93 - 78 = 15

the final has the greatest iqr

6.   b - there is a high data value that causes the data set to be asymmetrical for the males: the data for males are high and asymmetrical .   there is an outlier for the males that skews the data

5.   the   iqr is a better measure of spread for the movies and basketball games.   since the basketball game has an outlier, we do not want to use standard deviation for measurement.  

3.   the exam median is much higher than the class median.   the median line is farther to the right on the exams

2.   there is no way to tell what the means are from the box and whisker plots.
