-4x +12 -12 = -4 -12
-4x = -16
x = 4
Answer:
no.
Step-by-step explanation:
Answer:
85/4 = 21 ,remainder =1
so
21 1/4
Step-by-step explanation:
Answer:
The correct answer would be 2π x 2²/5
Step-by-step explanation:
First, calculate the product, and evaluate the power which would be 2³π/5 and the solution is in an alternate form, therefore making it rational. :)
Answer:
Step-by-step explanation:
We would assume a binomial distribution for the handedness of the population. Let x be a random variable representing the type of handedness in the population. The probability of success, p is that a randomly chosen person is left handed only. Then probability of failure is that a chosen person is not left handed only(right handed only or both).
p = 12/100 = 0.12
number of success, x = 20
n = 200
the probability that there are at least 20 left-handers is expressed as P(x ≥ 20)
From the binomial probability calculator,
P(x ≥ 20) = 0.84
