LiRa [457]2 years ago
4 0

Answer:

Whole #'s: All natural numbers plus 0

Integers: Whole numbers and their opposites

Rationals: Can be expressed as ratios, repeating numbers, decimals, so on.

1.

-2/5 is a fraction or ratio, meaning it doesn't belong in whole NOR integer.

-2/5 belongs in the rationals box.

-7.8 is negative, but it is a decimal, so it belongs in the rationals box.

1/10 is not a whole, not an integer, but a rational number.

13 is a whole number, integer, and rational, so it belongs in the whole box.

10 is also a whole number grouped under the categories given.

-5 is the opposite of 5, and whole numbers aren't negative, so -5 belongs in the integers box.

-8/4 is a fraction, not considering its simplified form that would give -2, so it belongs in the rationals box.

2.

We know there are 208 pages in total. On Monday, she read 3/8 of the pages. This can be demonstrated as 208 * 3/8, which is 78. 208-78 = 130.

We know there are 130 pages left. On Tuesday, she reads 28 pages. 130-28=102

We know there are 102 pages left. On Wednesday, she read 1/4 of the total pages. 1/4 (of) 208 is 1/4*208, that is 52.

To know how many pages are left, we subtract her read pages from the remaining pages. 102-52 = 50.

Amanda has 50 pages left until she finishes the novel.

Hope this helped.

In a teacher's math course, a linear regression line was calculated to predict
Marat540 [252]

The given equation is the best line that approximates the linear

relationship between the midterm score and the score in the final exam.

  • AJ's residual is 0.3, which is not among the given options, therefore, the correct option is. <u>E. None of these</u>.

Reasons:

The given linear regression line equation is; \hat y = 25.5 + 0.82·\mathbf{\hat x}

Where;

\hat y = Final exam score;

\hat x = The midterm score;

AJ score in the first test, \hat x = 90

AJ's actual score in the exam = 99

Required:

The value of AJ's residual

Solution:

By using the regression line equation, we have;

The predicted exam score, \hat y = 25.5 + 0.82 × 90 = 99.3

  • The residual score = Predicted score - Actual score

∴ AJ's residual = 99.3 - 99 = 0.3

AJ's residual = 0.3

Therefore, the correct option is option E;

  • <u>E. None of these</u>

A right angled triangle has two shorter sides and one is twice as long as the other. The hypotenuse is 25cm long. What are the l
Bas_tet [7]

Answer:  x =  14.43

Step-by-step explanation:

The Pythagorean Theorem states the following:  

a^2 + b^2 = c^2  

Make one side of the triangle x  

Make the second side of the triangle 2x  

Now, you can plug the values into the equation,  right?  

x^2 + 2x^2 = 25^2 or 625  

3x^2 = 625

Divide each side by 3 and you are left with:  

x^2 =  208.33

Now, take the square root of 208.33

x =  14.43

That is the shorter side. The longer side is twice that value: Therefore, 14.43 x 2 = 28.86 14.43 is one side of the triangle. The other is that same value times two. Therefore, the sides of your triangle are: 14.43 Shorter side 28.86 Longer side
