In a study designed to predict blood cholesterol levels from amount of daily saturated fat in grams (X1) and the number of hours of daily exercise (X2), the slope of X1 is 5, the slope of X2 is –4, and the y intercept is 130.

a) If an individual reports that he or she typically eats 15 grams of saturated fat daily and exercises 1 hour every day, what would be the predicted cholesterol level for this individual?

i) -180

ii) -201

iii) -75

iv) -145

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.

because they could drop even lower..

answer: 1, 3 and 5 are correct

step-by-step explanation:

$12. that is my answer.
