Answer: B. x ~ B(50, .1)
In other words, it's the second answer choice
===========================================================
Explanation:
We have n = 50 people in the sample and p = 0.10 is the decimal form of 10%, to represent the probability of success. In this case, we define "success" as "the person passes the fitness test".
The random variable x is the count of how many people pass. So we could have x = 0, x = 1, x = 2, ..., x = 49, x = 50. Basically any whole number from 0 to 50 inclusive. Furthermore, x is approximately modeled by the binomial distribution which we denote as B(n, p) = B(50, 0.1)
So X ~ B(50, 0.1)
Step-by-step explanation:
substitute the values
px=3x+1
=(3x+1)/x
=3x/x +1/x
=3+1/x
rx=2x²+5
p(r(x)) =(3+1/x(2x²+5))
=6x²+15+2x²/x+5/x
=3(2x²+5)+1/x(2x²+5)
=(2x²+5)(3+1/x)
Answer:
C
Step-by-step explanation:
cross multiply
Answer:
3/2
Step-by-step explanation:
Basically just multiply 1/2 by numbers.
1/2 * 2 = 1
1/2 * 3 = 3/2
1/2 * 4 = 2
1/2 * 5 = 5/2
And so on.
