In a regression equation predicting income (measured in $1000s) with education (measured in years), the intercept (a) equals 1.5
Sindrei [870]

Answer:

a. at zero years of education, income equals $1500

Step-by-step explanation:

The equation for income 'I', as a function of years of education 't' is given by:

i(t) = bt+a

Where b is the regression coefficient and a is the intercept.

The intercept is the value assumed by the function for t = 0 years of education:

i(0) = 0*4 +1.5\\i(0) = 1.5

Since the income function measures income in $1,000s, at zero years of education, income equals $1500

Solve the quadratic equation by factoring. 9x^2+24x+20=4
const2013 [10]

D. -4/3

Let's solve your equation step-by-step.

9x2+24x+20=4

Step 1: Subtract 4 from both sides.

9x2+24x+20−4=4−4

9x2+24x+16=0

Step 2: Factor left side of equation.

(3x+4)(3x+4)=0

Step 3: Set factors equal to 0.

3x+4=0 or 3x+4=0

x= −4 /3

Hope This helps

Jo estimated the quotient of –41.71 divided by –6.03 by rounding each to the nearest integer. What is Jo’s error?
kicyunya [14]
I cant see Jo's error...but the correct way is this :
-41.71 rounds to -42
-6.03 rounds to -6

so the quotient is : -42/-6 = 7 <==
