Ahmad and Bryson are in a long-term fitness challenge that involves counting how many calories they consume on daily basis. Let A = the number of calories Ahmad consumes daily, and B = the number of
calories Bryson consumes daily. Based on previous data, they know that A = 2200 calories and
A = 300 calories. They also know that pib = 2400 calories and ob = 400 calories.
Assume that their daily calorie counts are independent, and let D be the difference between the number of
calories they each consume on a randomly selected day (D=B - A).
Find the mean of D.

calories

Using the mean of the subtraction, it is found that the mean of D is of 200 calories per day.

In this problem:

Subtracting the means, 2400 - 2200 = 200 calories per day.

Hence, the mean of D is of 200 calories per day.

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.
