In a statistics course, a linear regression equation was computed to predict the final exam score from score on the midterm exam
Bingel [31]

Answer: c. 91

Step-by-step explanation:

Given : A linear regression equation was computed to predict the final exam score from score on the midterm exam.

The equation of the least squares regression line was

Y = 10 + 0.9x

, where y= the final exam score

x= the midterm exam score.

if Joe score a 90 on the midterm exam, the put x= 90 in the above eqaution , we get

Y = 10 + 0.9(90)

\Rightarrow\ Y = 10 + 81=91

Hence, the predicted value of his score on the final exam would be 91.

Therefore , the correct answer is c. 91 .

Write the sum, and then write an equivalent expression by collecting like terms and removing parentheses whenever possible.
Yanka [14]

Answer:

The sum is t.

Step-by-step explanation:

Consider the provided information.

The given expression are - 10t and t - 10t

We need to find the sum of the opposite of -10 t and t - 10t.

The opposite of -10 t is 10 t.

10t+(t-10t)

Remove the parenthesis.

10t+t-10t

Simplify the number

10t-10t+t

Use Additive inverse.

t

Hence, the sum is t.

Write the equation of a circle centered at the
Fudgin [204]

Answer:

(x+4)^2+(y+6)^2=100

Step-by-step explanation:

Given a circle centred at the point P(-4,-6) and passing through the point

R(2,2).

To find its equation, we follow these steps.

Step 1: Determine its radius, r using the distance formula

For point P(-4,-6) and R(2,2)

\text{Distance Formula=}\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\\text{Radius=}\sqrt{(2-(-4))^2+(2-(-6))^2} \\=\sqrt{(2+4))^2+(2+6)^2}\\=\sqrt{6^2+8^2}\\=\sqrt{100}\\Radius=10

Step 2: Determine the equation

The general form of the equation of a circle passing through point (h,k) with a radius of r is given as: (x-h)^2+(y-k)^2=r^2

Centre,(h,k)=P(-4,-6)

r=10

Therefore, the equation of the circle is:

(x-(-4))^2+(y-(-6))^2=10^2\\\\(x+4)^2+(y+6)^2=100
