The students in the eighth grade at North Middle School were asked to take a pop quiz with a maximum score of 200.

If 3 of the students who scored below 140 decide to drop the class, what would be the shape of the distribution?
A.
The distribution would exhibit a positive skew.
B.
The distribution would exhibit a negative skew.
C.
The distribution would be symmetric about the mean.
D.
The distribution would be uniform.
E.
The distribution would be asymmetric with no skew.

B.) Negative Skew

Step-by-step explanation:

You can tell by the overall shape of the graph. If you dropped the left-most 3 the graph would still lean to the right making it negative.

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer
