Answer:
Domain = {1,2,3,4,5,6} and Range = {42,49,56,63,70,77}
Step-by-step explanation:
The given function is :
y = 7x + 35
Where
x is no of members
y is the monthly cost
Your group has enough money for up to six members to joim fitness club. It means domain (the set of input values) are:
Domain = {1,2,3,4,5,6}
Put x = 1 to 6 one by one,
y = 7(1) + 35 = 42
y = 7(2) + 35 = 49
y = 7(3) + 35 = 56
y = 7(4) + 35 = 63
y= 7(5) + 35 = 70
y = 7(6) + 35 = 77
Range = {42,49,56,63,70,77}
<h3><u>Question:</u></h3>
Mitch lost 10/3 pounds in 5/7 in a week. Which complex fraction, when simplified, will compute the unit rate of pounds per week?
A)10/3 over 5/7
B)10/3 over 7/5
C)3/10 over 5/7
D)5/7 over 10/3
<h3><u>Answer:</u></h3>
Option A
The unit rate of pounds per week is 10/3 over 5/7
<h3><u>Solution:</u></h3>
Given that,
Mitch lost pounds in of a week
We have to compute the unit rate of pounds per week
Unit rate means that number of pounds lost in 1 week
From given information,
So to find the number of pounds lost in 1 week, divide the total pounds lost (10/3) by the time in weeks (5/7)
Thus unit unit is 10/3 over 5/7
Answer: a) No, b) 0.78, c) No.
Step-by-step explanation:
Since we have given that
P(A) = 0.7
P(B) = 0.2
P(A∩B) = 0.12
(a) Are A and B independent? Explain.
Since P(A).P(B) =
And P(A∩B) = 0.12
P(A∩B) ≠ P(A).P(B)
So, they are not independent.
(b) Compute P(A or B).
(c) Are A and B mutually exclusive? Explain
Since P(A∩B) ≠ 0
So, they are not mutually exclusive.
Hence, a) No, b) 0.78, c) No.
Answer:
Answer is 80
Step-by-step explanation:
PEMDAS (Parentheses - Exponents - Multiplication - Division - Addition - Subtraction)
Do (3+7) first which equals 10.
Your equation is then simply 8 x 10 which is 80.
