Answer:

J probably

Step-by-step explanation:

When multiplying the rectangle's sides by 1.5 you get the rectangle F.

When multiplying the sides by 1/4 you get G.

When multiplying by 1.25 you get H.

To get J, you would need to muliply 8 by 1.25 and 2 by 2. There is no scale factor that would result in the rectangle ABCD turning into J.

Step-by-step explanation:

A withdraw means taking out -225  dollars

The line y = 4.08x + 63.13 is a good fit for this data because it accurately represents the positive relationship between median household income and the number of adults with bachelor's degrees in the 50 U.S. states.

Given that a scatter plot of median household income x and the number of adults per 1,000 people with bachelor's degrees y for 50 U.S. states. The line y = 4.08x + 63.13 is suggested to be a good fit for this data.

To understand why this line is a good fit, to consider its equation. In this case, y represents the number of adults per 1,000 people with bachelor's degrees, and x represents the median household income in thousands of dollars.

The equation of the line is y = 4.08x + 63.13. This means that for every increase of $1,000 in median household income, the number of adults with bachelor's degrees increases by 4.08 per 1,000 people. The intercept of the line is 63.13, which represents the number of adults with bachelor's degrees when the median household income is $0.

By analyzing the scatter plot, we can see that the points are roughly linear and show a positive correlation between median household income and the number of adults with bachelor's degrees. The line represents the best fit for this data because it minimizes the distance between the line and the points on the scatter plot.

Hence, the line y = 4.08x + 63.13 is a good fit for this data because it accurately represents the positive relationship between median household income and the number of adults with bachelor's degrees in the 50 U.S. states.

Your answer is c)

Answer:

2√5

Step-by-step explanation:

The triangle that's shown on the page is a special isosceles right triangle with angle measures of 45° - 45° - 90°

Since one of the side length that sees 45° angle measure is 2√5 the other also has to be equal to this value so the answer is 2√5

Answer:

Jared did not get the correct answer. The solution to his equation is k = 3, giving 3, 4, and 5 as the three integers. However, 3 and 5 are not even integers. He should have used the equation:

[tex]\displaystyle k+(k+2)+(k+4) = 4k[/tex],

which gives us k = 6, and the correct answer 6, 8, and 10.

Step-by-step explanation:

Jared wanted three consecutive even integers, whose sum is 4 times the first integer.

He let k represent the first integer and wrote:

[tex]k+(k+1)+(k+2)=4k[/tex]

We can solve this first. Combine like terms:

[tex]3k+3=4k[/tex]

So:

[tex]k=3[/tex]

This means that our sequence will be 3, 4, and 5, which is not correct since we have odd integers.

Jared did not get the correct answer. The solution to his equation is k = 3, giving 3, 4, and 5 as the three integers. However, 3 and 5 are not even integers. He should have used the equation*:

[tex]\displaystyle k+(k+2)+(k+4) = 4k[/tex],

which gives us k = 6**, and the correct answer 6, 8 , and 10.

To verify, 6 + 8 + 10 = 24.

And 6(4) = 24, so our answer is correct.

**To solve, we can combine like terms:

[tex]3k+6=4k[/tex]

So:

[tex]k=6[/tex]

*The reason we use (k + 2) instead of (k + 1) is because (if k is an even number), then adding 2 guarantees another even number. If we added only 1, we will get odd numbers.
