1). 662.4
2). $8.89
3). $100.80
4). $7.54
5). $4.18
6). 27 (but I'm not 100% sure)
Step-by-step explanation:
f(x) = 8 - 3x
when x =3, then
f(3) = 8 - 3×3
=8-9
=-1
Answer:
Option A is correct.
A uniform distribution.
Step-by-step explanation:
Complete Question
T-Mobile sells 6 different models of cell phones and have found that they sell an equal number of each model. The probability distribution that would describe this random variable is called:
A) Uniform Distribution
B) Continuous Distribution
C) Poisson Distribution
D) Relative Frequency Distribution
Solution
A uniform distribution is one in which all the variables have the same probability of occurring.
It is also known as a rectangular distribution, as every portion of the sample space has an equal chance of occurring, with equal length on the probability curve, leading to a rectangular probability curve.
And for this question, 6 different models of phones sell an equal number, hence, the probability of selling each model is equal to one another, hence, this is evidently a uniform distribution.
Hope this Helps!!!
Which of the following sets represent A ∪ B? {6, 12} {2, 3, 4, 6, 8, 9, 10, 12} {1, 5, 7, 11} {2, 3, 4, 8, 9, 10}

<h3>AUB = { 2, 3, 4, 6, 8, 9, 10, 12}</h3>
<em><u>Solution:</u></em>
The complete figure of question is attached below
From figure,
Write all elements from set A
A = {3, 6, 9, 12}
Write all elements from set B
B = {2, 4, 6, 8, 10, 12}
AUB means A union B
AUB means set of all the numbers combined with set A and set B
Combine set A and B
AUB = { 2, 3, 4, 6, 8, 9, 10, 12}
Thus AUB is found
Consider the number 
.
Since the numerator is greater than the denominator, this fraction is greater than 1.
Now, in the number line, find out how many 13's are there within 27.
The answer is 2.
Now, subtract 2 × 13 from 27.
27 - 26 = 1
Hence, the required mixed fraction is
