The scale factor that was used to create triangle J’K’L’ is 1/3

<h3>How to determine the scale factor?</h3>

From the graph, we have the following highlights:

KL = 3

K'L' = 1

The scale factor (k) from JKL to J'K'L is calculated as:

Scale factor = K'L'/KL

This gives

k = 1/3

Hence, the scale factor that was used to create triangle J’K’L’ is 1/3

Allison bought some shirts for he clothing store for $15 each. She received $50 off her entire purchase and spent a total of $40

k0ka [10]

The $50 off was like a coupon after you brought all your merchandise to the counter, so we have to add it back in to determine the number of shirts.

$400+$50=$450 original price of shirts

Original price ÷ price per shirt= quantity purchased

$450 ÷ $15/shirt= 30 shirts purchased

Allison bought 30 shirts.

Hope this helps! :)

love history [14]

Answer:

She need to walk 31/75 miles to school.

Step-by-step explanation:

It is given that,

Sofia has walk $1\dfrac{2}{25}$ miles to school. She has already walk $\dfrac{2}{3}$ of a mile.

We need to find how much farther does she need to walk.

Total distance = $1\dfrac{2}{25}$ $=\dfrac{27}{25}$

Let she has to walk x distance to school.

$x=\dfrac{27}{25}-\dfrac{2}{3}\\\\=\dfrac{31}{75}$

Hence, she need to walk 31/75 miles to school.

Vince bought 6 boxes of worms to use as bait while fishing with his friends. If each person uses exactly 3/8 of a box of worms,

tia_tia [17]

We are given the following information:

<em />

<em>each person uses 3/8 a box</em>

<em>there are 6 boxes</em>

Because each box is $\frac{8}{8}$ , and there are 6 boxes, we know that 1 person is $\frac{3}{8*6}$ , or $\frac{3}{48}$ .

In order to find how many people can use the 6 boxes, we can divide it by 3 (for each use):

48 / 3 = 16

Therefore, 16 people can share the worms.

Liono4ka [1.6K]

Answer:

<h2>Option E is correct.</h2>

Step-by-step explanation:

In a survey of 1,000 adults living in a big city, 540 participants said that they prefer to get news from the Internet, 330 prefer to watch news on TV, and 130 are rarely interested in the current news. We want to test if the proportion of people getting the news from the Internet is more than 50%. By generating the randomization distribution, we find that the p-value is 0.0057. Choose the correct statement interpreting the p-value.

A.If the proportion of people getting the news from the Internet is not equal to 0.5 then there is a 0.0057 chance of seeing the sample proportion as extreme as the survey results.

B. If the proportion of people getting the news from the Internet is not equal to 0.54 then there is a 0.0057 chance of seeing the sample proportion as extreme as the survey results.

C. If the proportion of people getting the news from the Internet is equal to 0.54 then there is a 0.0057 chance of seeing the sample proportion less extreme compared to the survey results. р

D. If the proportion of people getting the news from the Internet is equal to 0.54 then there is a 0.0057 chance of seeing the sample proportion as extreme as the survey results.

E. If the proportion of people getting the news from the Internet is equal to 0.5 then there is a 0.0057 chance of seeing the sample proportion as extreme as the survey results.

The correct interpretation of P value will be:

if the proportion of people getting the news from internet is equal to 0.5 then there is a 0.0057 chance of seeing the sample proportion as extreme as survey results.

<h2>Option E is correct.</h2>
