A. 75 x 0.0016= .12 Has a value between 0 and 1
B. 3^5 / 3^-6 = 177147 Does not a value between 0 and 1
C. 1/4^3 x 1/4^2 = about 0.0009 Has a value between 0 and 1
D. -7^5 / -7^7 = about 0.02 Has a value between 0 and 1
Answer:
See below
Step-by-step explanation:
In an odd function f(-x) will equal -f(x).
An example is f(x) = x^3:-
f(-x) = (-x)^3 and -f(x) = -x^3:-
(-x)^3 = -x * -x * -x = -x^3.
Answer:
The approximate margin of error = ± 0.1131607
Step-by-step explanation:
By margin of error = ± Z *
We assume 95% confidence interval. Thus Z = 1.96. Since the survey is about support or oppose, we assume equal proportion: 50% for and 50% against.
Hence, margin of error = ± 1.96* ((0.5*0.5)/75)^(0.5)
= ± 0.1131607
Answer:
Product Rule
Step-by-step explanation:
According to the product rule, the number of possibilities of two independent events happening in sequence, is given by the product of both number of possibilities.
In this case, since there are 17 mathematics majors and 325 computer science majors and they do not overlap, the total number of ways to pick two representatives so that one is of each major is:
n = 17 x 325 = 5,525.
