Answer: the probability that exactly two of the next five people who apply to that university get accepted is 0.23
Step-by-step explanation:
We would number of people that applies for admission at the university and gets accepted. The formula is expressed as
P(x = r) = nCr × p^r × q^(n - r)
Where
x represent the number of successes.
p represents the probability of success.
q = (1 - p) represents the probability of failure.
n represents the number of trials or sample.
From the information given,
p = 0.6
q = 1 - p = 1 - 0.6
q = 0.4
n = 5
the probability that exactly two of the next five people who apply to that university get accepted is
P(x = 2) = 5C2 × 0.6^2 × 0.4^(5 - 2)
P(x = 2) = 10 × 0.36 × 0.064
P(x = 2) = 0.23
Set the 2x - 1 equal to 9 then work backwards. 2x - 1 = 9 Nine minus one is eight divided by two is four. X = 4
A=future amount
P=present amount
r=rate in decimal
n=number of times per year compounded
t=time in years
given
P=455
r=4%=0.04
n=1
t=2
A=492.128
round
$492.13
3rd option
Answer:
you require two numbers m and n such that. x² + bx + c = (x - m)(x - n) where. m + n = b. and. mn = c. In the case where c = 22 and m & n are integers, we have. mn = 22. But, the (positive) …
Step-by-step explanation:
Distribute the 4 into the parenthesis by multiplying the numbers by 4.
New expression is:
24m-28
