Answer:
Part a: So the number of business owners giving holiday gift to their employees from survey is 12.
Part b: p-value is 0.00003
Part c: value of p is less that a we reject the null hypothesis.
Step-by-step explanation:
Part a
number of business owners=20% x n
number of business owners= 0.2x 60
number of business owners=12
Part b
H0: p=0.46
H1: p<0.46
Here
n=60, 
=0.2, p=0.46
So test statistics is given as
p-value is P(z<-4.04)= 0.00003
Part c
As value of p is less that a we reject the null hypothesis.
We know that
the addition rule states that
P(A or B) = P(A) + P(B) − P(A and B)
in this problem
P(A)=0.72
P(B)=0.84
P(A and B)=0.64
so
P(A or B) = P(A) + P(B) − P(A and B)-----> 0.72+0.84-0.64
P(A or B) = 0.92
the answer is
0.92 (92%)
Recallin that, the diameter is twice as long as the radius, namely the radius is half the diameter, so, if the diameter is doubled, the radius is also doubled.
notice, the new volume is 4 times (πr² h), namely 4 times the original.
Answer:
1
Step-by-step explanation:
f(1) is simply the value of f(x) when x = 1. Therefore, looking at the graph, when x = 1, f(x) = 1.
Answer:
The range would be all real numbers
Step-by-step explanation:
In order to find (wor)(x), we need to start with the w(x) equation and then input the r(x) equation for every x in the w(x) equation.
w(x) = x - 2
(wor)(x) = (2 - x^2) - 2
(wor)(x) = -x^2
Given this equation, we know that x can be all real numbers
