A regression was run to determine whether there is a relationship between hours of tv watched per day(x) and number of sit-ups a

lisabon 2012 [21]

Answer:

Step-by-step explanation:

Given the regression model :

Y=ax+b

x = Hours of TV watched per day

y= number of sit-ups a person can do

A=-1.341

B=32.234

Y = - 1.341x + 32.234

Predict Y, when x = 11

Y = - 1.341(11) + 32.234

Y = −14.751 + 32.234

Y = 17.483

Hence, the person Cann do approximately 17 sit-ups

Answer:

$-\frac{21}{2}$

Step-by-step explanation:

We can solve this system just by summing each side of the equation:

So, both left sides will be sum, and both right sides too.

The resulting expression will be:

$(3-y)+(3-y) = 6+21$

Ordering and solving both sides:

$6-2y=27\\-2y=27-6\\y=\frac{21}{-2}$

Hence, the value to the system is $-\frac{21}{2}$

It's important to combine both equation, because the exercise is asking for the solution of the system.
