Question 5: a recent cnn news survey reported that 76% of adults think the u. s. pennies should still be made. suppose we select a sample of 20 people.

how many of the 20 would you expect to indicate that the treasury should continue making pennies?

what is the standard deviation?

what is the likelihood that exactly eight people would indicate the treasury should continue making pennies?

what is the likelihood that 10 to 15 adults would indicate the treasury should continue making pennies?

215.92 dollars is the answer

57.09 minus 7.0435 equals

step-by-step explanation:

just subtrach them both and u get the answer of 50.0465

step by step resolutions

1) n+n+1+n+2=51

3n+3=51

3n=48

n=16

the three numbers are 16, 17 and 18.

2) x+15=4x

3x=15

x=5

3) the two digits are x and y.

y=3x

(10x+y)+(10y+x)=88

y=3x

11x+11y=88

y=3x

x+y=8

x+3x=8

x=2

the original number can be either 28 or 82.

4) n+(n+2)+(n+4)=48

3n+6=48

3n=42

n=14

the numbers are 14, 16 and 18.

5) y=x+3

10y+x+10x+y=143

y=x+3

11x+11y=143

y=x+3

x+y=13

x+x+3=13

2x=10

x=5

the original number can be 57 or 75.

hope this !
