Darina [25.2K]

Answer:

0.5375

Step-by-step explanation:

The point estimate of  proportion of all Americans who are in favor of outlawing cheese can be computed as

p=x/n

Here. x is the number of favorable outcomes and n is sample size.

We are given that x=2150 and n=4000, So,

p=2150/4000

p=0.5375.

Thus, the point estimate of  proportion of all Americans who are in favor of outlawing cheese is 0.5375.

mote1985 [20]

Answer:

$7200 in the fund rose 6% n $2800 in the fund rose 9%

Step-by-step explanation:

let x be the amount in the fund rose 6%

gain in one year=x*6%=0.06x

total amount is 10000

so amount in the fund rose 9% = 10000-x

gain in one year=(10000-x)*9%=900-0.09x

total gain=0.06x+900-0.09x=900-0.03x

=684

900-684=0.03x

0.03x=216

x=7200

the other fund amount=10000-7200=2800
