Both the sample can be used to make inferences about the population.

Given that,

Jason and Yolanda both drew a simple random sample from a non-normally distributed population of 25,000.

Jason’s sample consisted of 0.24% of the population, while Yolanda’s sample consisted of 0.32% of the population.

We have to find,

Whose sample can be used to make inferences about the population?

According to the question,

Total number of population = 25000

Percent of the sample of Jason = 0.24%

Percent of the sample of Yolanda's = 0.32%

Then,

The number of the population according to Jason's sample is given by,

=\dfrac{ Sample \ of \ population \ in \ percentage}{100} \times {Total \ number \ of \ population}\\\\= \dfrac{0.24}{100} \times 25,000\\\\= 0.24 \times 250\\\\= 60

And the number of the population according to Yolanda's sample is given by,

=\dfrac{ Sample \ of \ population \ in \ percentage}{100} \times {Total \ number \ of \ population}\\\\= \dfrac{0.32}{100} \times 25,000\\\\= 0.24 \times 250\\\\= 80

Hence, Both the sample can be used to make inferences about the population.

Part of the roof of a factory is devoted to mechanical support and part to green space. The area G that is designated as green s
alexgriva [62]

Answer:

Therefore, the area of green space would be 30 square yards.

Step-by-step explanation:

The area G that is designated as green space can be modeled by the polynomial 2x^2-7x

the area M that is devoted to mechanical support can be modeled by the polynomial x^2-9x+24.

We are asked to find the area of the green space, when area of roof (R) is 36 square yards.

The area of roof would be equal to sum of areas of green space and mechanical support.

R=G+M

G = 2x^2 -7x M = x^2 -9x +24

the total area is given by 36 yd^2. And we know that:

R = 36 yd^2 = G+M

Replacing the info given we got:

36 = 2x^2 -7x +x^2 -9x +24\\\\ 12= 3x^2 -16 x

And we can rewrite this expression like this:

3x^2 -16 x -12 =0

And we can use the quadratic formual to solve this problem:

X =\frac{-b \pm \sqrt{b^2 -4ac}}{2a}

With a = 3, b = -16 , c =-12. Replacing we have

x = \frac{16 \pm \sqrt{(-16)^2 -4*(3)*(-12)}}{2*3}

And the solutions for this case are:

Since length cannot be negative, therefore, the value of x would be 6.

The area of green space would be:

x = 6

2x^2-7x\Rightarrow 2(6)^2-7(6)\\\\2x^2-7x=2(36)-42\\\\2x^2-7x=72-42\\\\2x^2-7x=30

the area of green space would be 30 square yards.

KonstantinChe [14]

Answer:

The answer is 500

Step-by-step explanation:

When you round to the hundred, you look at the 10s place. If the 10s place is 5,6,7,8, or 9, you round the hundred up. In this case, it is 459 so you would round up to 500. Have a nice day!!!
