Answer:
what
Step-by-step explanation:
<u>Given</u>:
The perimeter of a polygon is the sum of the lengths of the sides of the polygon.
Given that the sides of the polygon are x + 1, 3x - 2, 3x - 2, x + 1.
We need to determine the perimeter of the polygon.
<u>Perimeter of the polygon:</u>
The perimeter of the polygon can be determined by adding the lengths of the sides of the polygon.
Thus, we have;
Removing the parenthesis, we get;
Adding the like terms, we get;
Thus, the perimeter of the polygon is 
Answer:
Yes!
Step-by-step explanation:
87 - 34 = 53
he would have $53 left
53-33 = 20
he would have $20 after buying both shirts

Step-by-step explanation: the way to find this answer is to add 10x3 then add 5 to that then add 25 in the end and you get 60 cents. Hope this helped!
Answer:
p = 0.38, n = 20
The probability that he throws more than 10 strikes = 0.09233
Step-by-step explanation:
Binomial distribution function is represented by
P(X = x) = ⁿCₓ pˣ qⁿ⁻ˣ
n = total number of sample spaces = number of times Jack wants to bowl = 20
x = Number of successes required = number of strikes he intends to get
p = probability of success = probability that Jack throws a strike = 0.38
q = probability of failure = probability that Jack doesn't throw a strike = 0.62
P(X > x) = Σ ⁿCₓ pˣ qⁿ⁻ˣ (summing from x+1 to n)
P(X > 10) = Σ ²⁰Cₓ pˣ qⁿ⁻ˣ (summing from 11 to 20)
P(X > 10) = [P(X=11) + P(X=12) + P(X=13) + P(X=14) + P(X=15) + P(X=16) + P(X=17) + P(X=18) + P(X=19) + P(X=20)
P(X > 10) = 0.09233
There are binomial distribution cacalculators that can calculate all of this at once. Get one to minimize errors.
