VEL A personal trainer wants to look at the relationship between number of hours of exercise per week and resting heart rate of her clients. The data show a linear pattern with the summary statistics shown below: mean standard deviation 2 hours of exercise per week Î= 8.9 8 = 4.8 y = resting heart rate (beats per minute) V = 74.3 $y = 7.2 r=-0.88 Find the equation of the least-squares regression line for predicting resting heart rate from the hours of exercise per week. Round your entries to the nearest hundredth. lum +​

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
