Answer:
0.3157
Step-by-step explanation:
Given that according to a certain news poll, 71% agreed that it should be the government's responsibility to provide a decent standard of living for the elderly,
Let A be the event that it should be the government's responsibility to provide a decent standard of living for the elderly, and B the event that it would be a good idea to invest part of their Social Security taxes on their own
P(B) = 41%=0.41
A and B are independent
Hence P(both)=
the probability that a person agreed with both propositions
= Probability for both A and B
= P(A) P(B) since A and B are independent
= 0.3157
Step 1
<u>Find the equation in function notation</u>
Let
h-------> the number of hours
y-------> the function for the walker fee in dollars
we know that
the hourly rate is
in this linear equation
the independent variable is the variable h
the dependent variable is the variable y
<u>Convert to function notation</u>
Let
Step 2
Find how much does the dog walker charge for a 45 minute walk
Convert the time in hours
substitute in the equation
For
therefore
<u>the answer is</u>
the dog walker charge for a 45 minute walk
<u>Statements</u>
Step 3
<u>The dependent variable is the number of hours true or false</u>
The statement is false,
because the independent variable is the number of hours and the dependent variable is the walker fee in dollars
Step 4
<u>The function for the walker fee is f(h)= 30h+6 true or false</u>
The statement is True --------> see the Step 1
Step 5
<u>The dog walker charges $22.5 for a 45 min walk true or false</u>
The statement is False
Because the dog walker charges for a 45 minute walk
