The number of books she would have completed in one day will be 2 books.
<h3>What is an expression?</h3>
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.
Given that:-
Emily completed reading 24/3 books in 32/4 days
Emily completed 8 books in 4 days. The number of the books will be calculated by using the expression below:-
4 days = 8 books
1 day = 8 / 4 = 2 books
Therefore the number of books she would have completed in one day will be 2 books.

Then the probability is
P(a)+P(b)-P(a&b)
0.5+0.3-0.5*0.3=0.8-0.15=0.65
Answer: 80
Step-by-step explanation:
Looking at the ratios in the table, the number of days to number of questions is 1:5 (4x5=20; 8x5=40;11x5=55). So for 16 days it will be 16x5=80
Answer:
y = -2/5x + 13
Step-by-step explanation:
First you should find the slope of the line on the graph. You move to the right 4 points and up 10 points. Since we write slope as rise over run you would get that m= 10/4 or 5/2
Now plug in the points and slopes into point slope form. y+2 = 5/2 (x+6)
We distribute y+2= 5/2x + 15
We subtract two to the other side y = 5/2x + 13
Now we have the equation of our line. To find the equation of the line PERPENDICULAR we flip our slope fraction and change the sign so our new slope will be m = -2/5
therefore, our equation will be y = -2/5x + 13
