Answer:

Using the information given, it is found that:

A linear function is modeled by:

[tex]y = mx + b[/tex]

In which:

Item a:

The slope is given by the change in y(total bill) divided by the change in x(number of days), hence:

[tex]m = \frac{506 - 338}{19 - 12} = 24[/tex]

The slope is of 24, which means that for each day, the total bill increases by $24.

Item b:

[tex]y = 24x + b[/tex]

[tex]338 = 24(12) + b[/tex]

[tex]b = 50[/tex]

Hence, the linear equation is: [tex]y = 24x + 50[/tex]

Answer/Step-by-step explanation:

✔️(3x² - 7x + 14) + (5x² + 4x - 6)

3x² - 7x + 14 + 5x² + 4x - 6 (distributive property)

Add like terms

3x² + 5x² - 7x + 4x + 14 - 6

8x² - 3x + 8

Therefore:

✅(3x² - 7x + 14) + (5x² + 4x - 6) is equivalent to expression 8x² - 3x + 8.

✔️(2x² - 5x - 3) + (-10x² + 2x + 7)

2x² - 5x - 3 - 10x² + 2x + 7 (distributive property)

Add like terms

2x² - 10x² - 5x + 2x - 3 + 7

-8x² - 3x + 4

Therefore:

✅(2x² - 5x - 3) + (-10x² + 2x + 7) is equivalent expression to -8x² - 3x + 4

✔️(12x² - 2x - 13) + (-4x² + 5x + 9)

12x² - 2x - 13 - 4x² + 5x + 9

12x² - 4x² - 2x + 5x - 13 + 9

8x² + 3x - 4

Therefore:

✅(12x² - 2x - 13) + (-4x² + 5x + 9) is equivalent expression to 8x² + 3x - 4

Answer:

14 one fourths

Step-by-step explanation:

First, we convert 7/2 into a fraction with the denominator of a four. To do this, we multiply the top and bottom by 2. 7*2 is 14, and 2*2 is 4, which gives us 14/4. This means that there are 14 one fourths in 7/2. Hope this helps!

Answer:

14 fourths

Step-by-step explanation:

Hey There!

So to solve this problem we need to divide 7/2 by 1/4

[tex]\frac{7}{2}divided by\frac{1}{4} =14[/tex]

Therefore 14 fourths can go into 7/2

6⁶/11

Step-by-step explanation:

adding -27/22 to the previous number will give you the next number in the sequence

10 5/22 + -27/22 = 9

9 + -27/22 = 7 17/22

7 17/22 + -27/22 = 6 6/11

6 6/11 + -27/22 = 5 7/22

Step-by-step explanation:

x = 1/2 ( a + b)

x = 1/2 (129 + 71)

x = 1/2 (200)

x = 100 °

you just have to remember that formula

Answer:

The answer is B.

Step-by-step explanation:

Two angles that add up to 90° are called complementary angles.

Angles A and B are complimentary angles. Complimentary angles are angles which add up to exactly 90 degrees.

They are often confused with supplementary angles, but supplementaries add up to 180.

Answer:

Nathan must order 21 sets of forks for the restaurant.

Step-by-step explanation:

Since Nathan needs to order some new supplies for the restaurant where he works, and the restaurant needs at least 571 forks since there are currently 361 forks, if each set on sale contains 10 forks, to determine the number of sets to buy you must perform the following calculation:

(571 - 361) / 10 = X

210/10 = X

21 = X

So Nathan must order 21 sets of forks for the restaurant.

Answer:

D i think i havent done this in a while

Step-by-step explanation:

This question is incomplete, the complete question is;

Suppose John is a high school statistics teacher who believes that watching many hours of TV leads to lower test scores. Immediately after giving the most recent test, he surveyed each of the 24 students in his class and asked them how many hours of TV they watched that week. He then matched each student's test grade with his or her survey response. After compiling the data, he used hours of TV watched to predict each student's test score. He found the least-squares regression line to be y"  = -1.5x + 85.

He also calculated that the value of r, the correlation, was -0.61.

what is the correct value of the coefficient of determination R² and give a correct interpretation of its meaning

Answer:

Interpretation of coefficient of determination R² = 0.3721

R² = 0.3721, meaning 37.21% of the total variation in test scores can be explained by the least square regression line

Step-by-step explanation:  

Given the data in the question;

the least square regression line is;

y"  = -1.5x + 85

the correlation coefficient r = -0.61

Now, the coefficient of determination R² is square of correlation coefficient r

R² = -61²

R² = 0.3721
