Answer:
x = 9.6
Step-by-step explanation:
The figure is a similar figure and the quadrilaterals (4 sides) created are related to each other by the same ratio.
So we can say:
8 goes with x as (8+12) goes with 24
We can setup a ratio and solve for x:
So x = 9.6

Answer:
z=1.96
Step-by-step explanation:
Using normal distribution table or technology, 97.5% corresponds to z=1.959964, generally denoted z=1.96, or 1.96 standard deviations above the mean.
