Quadratic Functions Put the equationy = x^2 + 14a + 40 into the form y = (x - h )^2 + k: Answer: y Preview Get help: Video Poins
Artist 52 [7]

Answer:

The required form is y=(x+7)^2-9.

Step-by-step explanation:

Consider the provided quadratic function.

y=x^2 + 14x + 40

We need to put the equation into the form y = (x - h )^2 + k

Add and subtract 49 in order to make the above function a perfect square.

y=x^2 + 14x+49-49 + 40

y=x^2 + 14x+7^2-49 + 40

y=(x+7)^2-49 + 40

y=(x+7)^2-9

Hence, the required form is y=(x+7)^2-9.

Use the given data to find the minimum sample size required to estimate a population proportion or percentage. Margin of error:
lisabon 2012 [21]

Answer: 191

Step-by-step explanation:

Formula to find the minimum sample size required to estimate a population proportion or percentage:

n= \hat{p}(1-\hat{p})(\dfrac{z^*}{E})^2

, where \hat{p} = proportion estimated by prior study.

E= Margin of error.

z* = Critical z-value.

Given : Confidence level = 95%

Critical value for 95% confidence = z*=1.96

\hat{p}=\ 42\%=0.42

E= 7%= 0.07

Then, n= 0.42(1-0.42)(\dfrac{1.96}{0.07})^2

n= 0.42(0.58)(28)^2

n= 0.2436(784)=190.9824approx191

Hence, the minimum sample size required=191
