The last one, because when you have to solve an equation, first you have to rearrange the equation, so that all the n’s are on one side of the equation and the numbers are on the other. Then, you just divide both sides by the number multiplying n to find the value of just one n. I hope this helped! I even included another example question that explains it a bit better.
Answer:
Step-by-step explanation:
Since the probability that Steven Adams makes any given free throw is fixed at 0.502, then this is a binomial probability. It is either he makes a free throw or he doesn't. The probability of success, p = 0.502
The probability of failure, q = 1 - p
q = 1 - 0.502 = 0.498
a) We want to determine P(x ≥ 7)
n = 8
Using the binomial probability calculator,
P(x ≥ 7) = 0.036
b) We want to determine P(x ≥ 70)
n = 80
Using the binomial probability calculator,
P(x ≥ 70) < 0.000001
c) Mean = np = 8 × 0.502 = 4.016
Standard deviation = √npq = √(8 × 0.502 × 0.498) = 1.41
d) Mean = 80 × 0.502 = 40.16
Standard deviation = √npq = √(80 × 0.502 × 0.498) = 4.47
If you do 30+20 you’ll get 50:)
37 + 57 = 57 + 37
Explanation: Commutative Property of Addition
Have an awesome day! :)<span />
You can find the value of p by dividing both sides of the equation by 2. Resulting in 3.5 as the answer
