Answer:
A) 1/3200000
B) 19/20
Step-by-step explanation:
Percentage population of graduates = 5
Proportion of graduates from 100 random samples = percentage × number of samples
Proportion of graduates = 0.05 × 100 = 5
Probability of having 5 graduates among the 100 random samples:
P(1 graduate) = possible outcome / total required outcome
P(1 graduate) = (5 / 100) = 1/20
P(5 graduates) = (1/20)^5
P(5 graduates) = 1/3200000
Probability of never being a graduate = (1 - probability of being a graduate)
Probability of never being a graduate = ( 1 - (1/20)) = 19/20
Answer:
2(4b-y)
Step-by-step explanation:
divide each term by HCF which in this case is 2
Answer:
p = 63
Step-by-step explanation:
3Q = p - 21
transfer the -21 to the left as the value of Q. Since it was negative, when we transfer it to the left it will turn to poditve so,
3(21) = p
multiply 3 and 21 so 3 multiplied by 21 is equal to,
63 = p, then the answer is p = 63
Hi there, so we know that all triangles add up to 180 degrees so we will take 38 and add it with 25 to get 63 then we subtract 180 by 63 to get 117 which is your awnser!! I mean I might be wrong but I’m probably right. I hope this helps!! Have a great morning, night, or day, Whatever it is for you!
