allochka39001 [22]

Answer:

−2x4−18x3y

Step-by-step explanation:

Let's simplify step-by-step.

(−3x2)(xy+2x2)+7x4−3x3(5y+x)

Distribute:

=(−3x2)(xy)+(−3x2)(2x2)+7x4+−3x4+−15x3y

=−3x3y+−6x4+7x4+−3x4+−15x3y

Combine Like Terms:

=−3x3y+−6x4+7x4+−3x4+−15x3y

=(−6x4+7x4+−3x4)+(−3x3y+−15x3y)

=−2x4+−18x3y

a random sample of 500500500 residents of a town included 173173173 residents who primarily spoke a language other than english
NNADVOKAT [17]

If sample size is 500,number of residents who primarily spoke a language other than english at home is 173, margin of error is 25 and the confidence level is 98%,then the number of residents from 25000 who primarily spoke a language other than english at home will be 9900.

Given that sample size is 500,number of residents who primarily spoke a language other than english at home is 173, margin of error is 25 and the confidence level is 98%.

We are required to find the number of residents from 25000 who primarily spoke a language other than english at home.

Percentage of residents who spoke language other than english at home=173/500 *100=34.6%

Percentage of margin of error=25/500*100=5%

Number of residents among 25000=25000*34.6%=8650

Margin of error for 25000=25000*5%=1250

Total number of residents who spoke other than english at home=8650+1250=9900 residents

Hence If sample size is 500,number of residents who primarily spoke a language other than english at home is 173, margin of error is 25 and the confidence level is 98%,then the number of residents from 25000 who primarily spoke a language other than english at home will be 9900.
