The two way-table shows the number of students in a school who like mathematics and/or physics.
how many more students like physics than mathematics?
a- 10
b- 15
c- 20
d- 25

 B- 15

Step-by-step explanation:

From the given two way-table , then number of students in a school who like mathematics = 20

The number of students in a school who like physics = 35

The number of students in a school who like mathematics and physics = 15

Now, the number of students like only Physics =

The number of students like only Mathematics=

Thus, the number of  students like physics than mathematics will be :-

answer:

step-by-step explanation:

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
