Answer:
47% of the students who chose pepperoni pizza as their favorite
Answer (D)
Step-by-step explanation:
∵ The total number of the students in grade 7 is
171 + 254 = 425 students
∵ The total number of the students in grade 8 is
285 + 143 = 428 students
∴ The total number of students in both grades is
425 + 428 = 853 students
∵ The number of students in grade 7 who like pepperoni pizza
as their favorite is 254
∵ The number of students in grade 8 who like pepperoni pizza
as their favorite is 143
∴ The number of students who like pepperoni pizza as their
favorite in both grades = 254 + 143 = 397 students
∴ % of student who chose pepperoni pizza as their favorite is
(397/853) × 100 = 46.5% ≅ 47%
∴ The answer is (D)

Answer: y = 1/2 x 7
Step-by-step explanation:
Get the apparent line that generally passes through the mean values of the values represented in the scatter plot. Find the Slope.
The easiest way is to the difference between the highest and lowest y-values (or the average of two of the highest and lowest) So around about 17.5 - 8.5 = 9 Divide by the difference in x-values 18- 1 = 17 9/17 ≈ .53 Round to .5 ≈1/2
Of the choices given, only the last one has the correct slope. If you were to graph this line, passing through the apparent mean of the values (about half the points above and half below the line) it would intersect the y-axis at about y=7
