Consider this option:
1. formula of perimeter is: P=2(a+b), where a & b - the sides of rectangle.
2. according to the condition 2(x+(x+4))<120; ⇒ x<28
answer: D. x<28
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
8x+6=62
8x=62-6
8x=56
X=56/8
X=7
The answer is 7. Hope this helps!
He would be 15 years old depending on his birthday if he has a late birthday he would be 14 years and if he had a early birthday he would be 16 years old
Given:

To find:
The values of f(2) and f(5).
Solution:
If an ordered pair
is in the function
, then
.
In the given set of ordered pairs one ordered pair is (2,3). So, by using the above definition, we get

In the given set of ordered pairs one ordered pair is (5,6). So, by using the above definition, we get

Therefore, the value of f(2) is 3 and the value of f(5) is 6.
