Solve y=15(9860)+6997 step by step please!! I'm Stupid :(
puteri [66]
I would probably distribute 15 with the parentheses 15x 9860 which is 147,900 then you would add 6997+147,900
Y= 154187

A regression was run to determine if there is a relationship between hours of TV watched per day (x) and number of situps a pers
Arturiano [62]

Answer:

A person who watches 8.5 hours of TV can do 30.4 sit ups.

Step-by-step explanation:

The regression equation is used to predict or estimate the value of the response (or dependent) variables using the information about the explanatory (or predictor) variables.

The general form of a regression equation is:

y=ax+b

Here,

<em>y</em> = dependent variable

<em>x</em> = independent variable

<em>a</em> = intercept

<em>b</em> = slope

The regression equation representing the relationship between hours of TV watched per day (<em>x</em>) and number of sit ups a person can do (<em>y</em>) is:

y=-0.74x+36.359

Compute the number of sit ups a person who watches 8.5 hours of TV can do as follows:

y=-0.74x+36.359

  =(-0.74\times 8.5)+36.359\\=-6.29+36.659\\=30.369\\\approx 30.4

Thus, a person who watches 8.5 hours of TV can do 30.4 sit ups.
