Answer:
27
Step-by-step explanation:
First you need to find x.
It is shown that DE=EF, so we can use this.
5x-3=3x+7
5x=3x+10
2x=10
x=5
Then, you plug in the value of the variable and solve.
6(5)-3
30-3
27 = DF
The answer is 6.89 because
6.89+14.52=21.41
So 21.41+(-14.52)=6.89
Its 25.2 but what do u mean by that
It's 100
Because You multiply the sample proportion to 2000
