Part a) is b part b) is b to
1. 22: 154 (divide 154 by 22)
1:7
if the figures are similar the ratio's of side lengths must be the same
12:b
multiply 12 by 7 to get side b
b = 84
Choice C
2: 1: 25 is the scale factor
6:tree
we need to multiply by 25
6*25 = 150
Choice C
Answer:
The distribution of scores on this final exam is left-skewed.
Step-by-step explanation:
We use the Pearson Mode Skewness to solve this question. It states that:
If the median is higher than the mean, the distribution is left-skewed.
If the median is lower than the mean, the distribution is right-skewed.
If the median is the same as the mean, the distribution is symmetric.
In this problem, we have that:
Median = 74
Mean = 70
Median higher than the mean
So the distribution of scores on this final exam is left-skewed.
