Can snacking on fruit rather than candy reduce later food consumption? Researchers randomly
assigned 12 women to eat either 65 calories of berries
or 65 calories of candy. Two hours later, all 12 women
were given an unlimited amount of pasta to eat. The
researchers recorded the amount of pasta consumed
by each subject. The women who ate the berries con-
sumed 133 fewer calories, on average. Identify the
explanatory and response variables, the experimental
units, and the treatments.

inequality:

620-37.4p ≥ 450

the minimum amount of packages needed to be removed from the elevator is 5.

step-by-step explanation:

answer: 1 and 3

step-by-step explanation:

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
