tankabanditka [31]

Answer:

1442

Step-by-step explanation:

Given,

Mean is,

$\mu = 20.4$

Standard deviation,

$\sigma = 8.8$ ,

Margin of error(E) = 0.54,

For 98% level of confidence, $z_{\frac{\alpha}{2}} = 2.33$

Thus, the sample size would be,

$n=[\frac{z_{\frac{\alpha}{2}}\times \sigma}{E}]^2$

$=[\frac{2.33\times 8.8}{0.54}]^2$

$=1441.74902606$

$\approx 1442$

Simplify the expression. Write the answer using scientific notation. (9 x 10)^2(2 x 10)^10

Valentin [98]

Answer:

Step-by-step explanation:

To multiply scientific notation, multiply each part of the number.

(9 x 10)^2(2 x 10)^10 = (9*2) * (10^ 2 + 10) = 18 * 10 ^ 12

Since scientific notation can only have a digit in the ones place from 1-9. 18*10^12 becomes 1.8*10^13.

The solution is B.
