Data on tuition and mid-career salary are collected from a number of universities and colleges. The result of the data collectio

alexira [117]

Answer:

1. annual tuition 2. $-27139 3. slope = -0.91

Step-by-step explanation:

1. An independent variable is the factor that is not determined by the model in this case the annual tuition variable (the linear regression model factor)

2. substitute $30,000 into the linear regressions equation gives:

y = -0.91(30000) + 161 = -27139

This value tells us that when the annual tuition is $30,000 the average mid-career salary of graduates is predicted to be -$27,139

3. the slope if the regression is represented by the coefficient of the factor in the linear regression model. In this case, as the factor is x or the annual tuition, and the coefficient of this variable in the given example is -0.91 which in turn is the slope of the model.

If a gallon of paint covers 400 square feet, how many gallons are needed to paint a retaining wall that is 269 feet long and 4 f

Nuetrik [128]

The area of a rectangular shape is given by

$A=l\times b$

Given:

It is given that a gallon of paint covers 400 square feet, and wall is 269 feet long and 4 feet high .

Now the area of wall will be

$A=269\times4$

Since,

$\begin{gathered} 400\text{ sq f}eet=\text{ 1gallon} \\ 1\text{ sq f}eet=\frac{1}{400}gallon \\ 269\times4\text{ sq f}eet=\frac{1}{400}\times269\times4 \\ =\frac{269}{100} \\ =2.69\text{ gallon} \\ =3\text{ galllon} \end{gathered}$

So, the ewall requires approx 3 gallon of paint.

PLEASE HELPPPPPP ASAPPP<br>I WILL GIVE BRAINLEST FOR THE CORRECT ANSWER

guajiro [1.7K]

Answer:

a. Find the multiples of 4 and 12 in the 30 to 40 range:

4 ⇒ 32, 36, 40

12 ⇒ 36

Answer = 36

b. Divisors of 24 ⇒ 2, 3, 4, 6, 8, 12, 24

Answer = 3

3 is the only odd divisor.

c. Gcd = Greatest common divisor that isn't zero.

35 divisors ⇒ 1, 5, 7, 35

42 divisors ⇒ 1, 2, 3, 6, 7, 14, 21, 42

Answer = 7

d. 98 divisors ⇒ 1,2,7,14,49,98

99 divisors ⇒ 1,3,9,11,33,99

Answer = 1

e. Answer = 25.

A number's greatest divisor is its own self.

Can someone check if my answers are right and help me figure out the blanks? Geometry: Sector Area

Leto [7]

Every thing looks good but for the blank I think they want the decimal representation of 1 / 3 which = .33333 Not sure though if that is what they are wanting. It is not very clear that is for sure.
