Answer:

- 11x² + 4x + 14

Step-by-step explanation:

Given

(9 - 3x²) + (- 8x² + 4x + 5) ← distribute both parenthesis by 1

= 9 - 3x² - 8x² + 4x + 5 ← collect like terms

= - 11x² + 4x + 14 ← sum of the polynomials

A student wants to estimate the mean score of all college students for a particular exam. First use the range rule of thumb to m

Wewaii [24]

Answer:

See explanation below

<u>Step-by-step explanation:</u>

range = 2200 - 300 = 1900

To find standard deviation, we have:

standard deviation = range/4 = $\frac{1900}{4}$ = 475

The range rule of thumb estimate for the standard deviation is 475

Given:

Standard deviation, $\sigma$ = 475

Margin of Error, ME = 100

$\alpha$ = 1 - 0.90 = 0.10

Za/2 = Z0.05 = 1.64

Find sample size, n:

n ≥ $[Z_\alpha_/_2 * (\frac{\sigma}{ME})]^2$

n ≥ $[1.64 * (\frac{475}{100})]^2$

n ≥ 60.68

≈ 61

Minimun sample size,n = 61
