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.
Answer: y=2
Step-by-step explanation:
2x+3y=14 - 2x-y=6 = 4y=8
y=2
If you need x, just insert y into the equation and work out x from there
2x-2=6
2x=8
x=4

Mark me as brain list plz
Step-by-step explanation:
I could not give the answer directly so I will give it to you by pic
Answer:
so originally there was 37 now there is 25 so if you trying to find out how many left you take 37-25=12 and 12 is how many left that zoo. hope this helps
i would appreciate the brainliest
