Mathematics

mezya [45]3 years ago

Y = mx + n

m = Slope

To two lines be perpendicular to each other the slopes need to meet the condition: ma x mb = -1

y = 2x + 5
ma = 2

D: y = -1/2x + 5
mb = -1/2

ma x mb = -1

2 x -1/2 = -1
2/1 x -1/2 = -1
-2/2 = -1
-1 = -1

It's true.

Answer: D.

leva [86]
<span>Given that A dataset shows that, on average, smokers do not live as long as nonsmokers and heavy smokers do not live as long as light smokers.

If you compute the least squares line for y = age at time of death and x = number of packets per day typically smoked, you will notice that as the number of packets per day a person smokes increases, the age at time of death of the person decreases.

Thus, the graph wil have a negative slope.

Therefore, the slope of your regression line will be less than 0.</span>

change in Dan's total pay for each copy of math is fun he sells is

= 2480 - 2400

=80

2. Dan's total pay if he doesn't sell any copies of math is fun?

y=80x+2400
