Answer:
Option C.
Step-by-step explanation:
Given information:
Male-Full stop = 6, Male-Rolling stop = 16, Male-No stop = 4
Female-Full stop = 6, Female-Rolling stop = 15, Female-No stop = 3
Using the given information we get
Total number of males = 6 + 16 + 4 = 26
Total number of males = 6 + 15 + 3 = 24
Probability of No stop is
We need to find the number of males that would we expect to not stop at all.
Expected number of males = Number of males × Probability
Expected number of males =
Expected number of males =
Therefore, the correct option is C.
Answer:
(2 , 5)
Step-by-step explanation:
point (x,y) that divides the segment PI in the ratio 2 to 1
PD=4 - (-2) = 6 PE/ED=2/1 PE=2ED PE+ED=6 3ED=6 ED=2 PE=4
coordinate of E (2,1) .... 2 is x coordinate of E
DI=7-1=6 DF/FI=2/1 DF=4
coordinate of F (4,5) .... .... 5 is y coordinate of E
CF // PD PC/CI=DF/FI=2/1
C (2,5)
