A college dining hall took a survey of 260 students on their favorite meals. one fifth of students selected macaroni and cheese as their favorite and 15% selected breakfast as their favorite answer. How many students chose a food other than the two above? a. 52
b. 65
c. 91
d.169

d. 169

Step-by-step explanation:

1/5 * ( 260) = 52

0.15 ( 260)=  39

out of 260 students 39 + 52 = 91 students chose a food / meal

the rest are 260 - 91 = 169 students chose a food other than the two

- 4

Step-by-step explanation:

Let the function is y = ax + b (1)

Now, the points (-4,-2) and (-2,-10) lie on the straight line, so the points will satisfy the equation (1).

Hence, - 2 = - 4a + b (2) and

- 10 = - 2a + b (3)

Now, solving equations (2) and (3) we will get the values of a and b.

Hence, - 2a = 8, ⇒ a = -4

Again from equation (3), we get b = - 10 + 2a = - 10 + 2(-4) = - 18

Therefore, the linear equation is y = - 4x - 18

Hence, the slope of the straight line is - 4. (Answer)
