The coefficient of determination measures the variation in the dependent variable that is explained by the regression model. 3. If your computed correlation coefficient is r = +1.2, then you have better than a perfect positive correlation. 4. A student might expect that there is a positive correlation between the age of his or her computer and its resale value. 5. In simple regression analysis, if the slope of the line is positive, then there is a positive correlation between the dependent variable y and the independent variable x. 6. The variable that is being predicted in regression analysis is the independent variable.

-4

step-by-step explanation:

(-4+8)=-(4-8)=-8+4=-4

income. 10x+1300

expenses 3x+(1800+1500)

expenses 3x+3300

to break even:

income = expense,

10x + 1300 = 3x + 3300,

solve for x.

a. (14,375+570)(5.3) b. 158,417$

step-by-step explanation:

a. you are basically just setting up the equation. f= amount of debt hence 14,375. g= how much she is borrowing from her parents weekly hence 570 and t= the interest on her debt. creating the equation.

b.   14,375+570= 14,945

      14,945 x 5.3 = 79,208.5

      79,208.5 x 2(years) = 158,417(answer)

85.3-64 = 21.3

so laura has already added 85.3 grams of chocolate powder and she has gone over the amount specified in the recipe by 21.3 grams

hope i ! have a great  day!
