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

step-by-step explanation:

square root means have of a number so have of 3 is 1.5 then multiply it by 8 and you get your answer!

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
