Answer: \mu=170\ ;\ \sigma=10.59

Step-by-step explanation:

Given : The proportion of households that were renters in 2011 : p= 0.34

Sample size : n= 500

The mean and standard deviation for binomial distribution is given by :-

\mu=np\\\\\sigma=\sqrt{np(1-p)}

Then , the  mean and standard deviation of the given sampling distribution :-

\mu=500(0.34)=170\\\\\sigma=\sqrt{500(0.34)(1-0.34)}\approx10.59

Solve 5x-y=5 and 2y-x^2=11 without using trial improvement
iren2701 [21]

Answer:

x = 7, y = 30  and  x = 3, y = 10

Step-by-step explanation:

5x - y = 5, then y = 5x - 5

2y - x^2 = 11

2(5x - 5) - x^2 = 11

10x - 10 - x^2 = 11

-x^2 + 10x -10 = 11

-x^2 + 10x -21 = 0

x^2 - 10x + 21 = 0

(x - 7)(x - 3) = 0

x = 7, y = 30

x = 3, y = 10

Which expression gives the best estimate of 45 percent of 76?
jonny [76]

Answer:

<h2>1/2 of 80</h2>

Step-by-step explanation:

45% is close to 1/2 (50%) and 76 is close to 80, so 1/2 of 80 is the best answer.

1/2 of 80 is 40

45% of 76 is 76 x 0.45 is 34.2

If m∠NOP = 24 and m∠NOQ = 110, what is m∠POQ? Angle N O Q divided into two unequal angles by ray O P. A. 62 B. 86 C. 134 D. 156I
lisabon 2012 [21]

Answer:

<em>B. 86 degrees</em>

Step-by-step explanation:

Given the following angles

m∠NOP = 24

m∠NOQ = 110

Required

m∠POQ

The following addition postulate is true for the angles

m∠NOQ = m∠NOP + m∠POQ

m∠POQ = m∠NOQ -m∠NOP

Substitute the angles given into the formula:

m∠POQ  = 110 - 24

m∠POQ  = 86°

<em>Hence the measure of angle POQ is 86 degrees</em>
