Answer:
The center for the distribution of scores appears to be higher for subject B than for subject A.
The mean of the distribution when X represent the score on a randomly selected exam so here the mean be like 2.95.
Calculation of the mean:Since
Column 1 is labeled score with entries 1, 2, 3, 4, 5.
Column 2 is labeled probability with entries 0.18, 0.20, 0.26, 0.21, 0.15.
So it be like
= (0.18) (1) + (0.20) (2) + (0.26) (3) + (0.21) (4) + (0.15) (5)
= 0.18 + 0.40 + 0.78 + 0.84 + 0.75
= 2.95
Hence, the third option is correct.

Triangle A B C is shown with its exterior angles. Line B A extends through point D. Line A B extends through point E. Line A C extends through point F. Which angle's measure is equal to the sum of the measures of ∠BAC and ∠BCA?
Answer:
∠CBE
Step-by-step explanation:
Find the diagram attached
Using the exterior property of a triangle which states that the sum of interior angles of a triangle is equal to the exterior angle.
Given the following from the diagram
Interior angles are ∠BAC and ∠BCA
Exterior angle = <CBE = a+b
Using the law above,
∠BAC + ∠BCA = ∠CBE
Hence the angle's measure that is equal to the sum of the measures of ∠BAC and ∠BCA is ∠CBE
Answer:
angleCBE
