Ron Finley is a gardener who decided a few years ago to plant several gardens in South Central Los Angeles. He wants his next ga

yaroslaw [1]

Well, we can be sure that whatever the width is, we can call it ' W '. Then, from information in the question, the length of the garden is ' 3W '.

Now, the perimeter of a rectangle is (length + width + length + width). Using the fancy algebra labels I just gave them, that's (3W + W + 3W + W). And now I can go through that, add up all the Ws, and get a total of 8W for the perimeter.

But he question tells us that the perimeter is 24 yards, so 8W = 24 yds.

Divide each side of that equation by 8, and we discover that W = 3 yds. And if THAT's true, then 3W = 9 yds. Bada bing ! We have the dimensions of the garden.

It's 3 yards wide and 9 yards long.

Find MO and PR <br> ............................................................

ddd [48]

MO = 12 and PR = 3

Solution:

Given $\triangle M N O \sim \Delta P Q R$ .

Perimeter of ΔMNO = 48

Perimeter of ΔPQR = 12

MO = 12x and PR = x + 2

<em>If two triangles are similar, then the ratio of corresponding sides is equal to the ratio of perimeter of the triangles.</em>

$$\Rightarrow \frac{\text{Perimeter of }\triangle MNO}{\text{Perimeter of }\triangle PQR} =\frac{MO}{PR}$

$$\Rightarrow \frac{48}{12} =\frac{12x}{x+2}$

Do cross multiplication.

$$\Rightarrow 48({x+2})= 12(12x)$

$$\Rightarrow 48x+96= 144x$

Subtract 48x from both sides.

$$\Rightarrow 48x+96-48x= 144x-48x$

$$\Rightarrow 96= 96x$

Divide by 96 on both sides, we get

⇒ 1 = x

⇒ x = 1

Substitute x = 1 in MO an PR.

MO = 12(1) = 12

PR = 1 + 2 = 3

Therefore MO = 12 and PR = 3.

g A researcher conducts a hypothesis test where he compares the scores of a random sample of students' SAT scores to the nationa

elena-s [515]

Answer:

Let level of significance is $\alpha$ =0.05

Since p-value is greater than alpha so students' mean score does not significantly differ from the national average.

Correct option is:

His students' mean score does not significantly differ from the national average, because his p-value is greater than alpha.

Let level of significance is $\alpha$ =0.10

Since p-value is less than alpha so students' mean score does significantly differ from the national average.

Correct option is:

His students' mean score does significantly differ from the national average, because his p-value is less than alpha.
