Step-by-step explanation:
Given that 5 pounds of rice at a store cost $6.50.
Then 1 pound of rice at a store cost = $6.50/5= $1.3
So the equation for the cost can be written as:
C=1.3P just like we write equation y=mx
Now we have to graph the cost C, vs pounds of rice.
Variable for Pounds of rice is not given so let it be "P"
So let's make a table for the number of pounds (P) and cost (C) we can graph the points from that table to get the final graph.
The Attached graph is the final graph.
Answer:
ANSWER IS C,,, 0

the J+8 is basically going along with that the answer J+8 could be LESS than or equal to 8 if we pick any other number its going to be GREATER than 8 an we want LESS than 8,,,hope this helps.
The time spent by the repairman there will be 3 hours so the correct answer is option D.
<h3>What is an expression?</h3>
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Given that:-
A roof repairman charges a $60 consult fee, and then $45 per hour to complete repairs. if the homeowner pays a total of $195.
The time will be calculated as:-
Total amount = $195
Now the fixed consulting cost will be $60 and will be deducted from the
total amount.
Variable cost = 195 - 60 = 135
The $45 per hour charge so for $145 the time will be:-
Time = 135 / 45
Time = 3 Hours
Therefore the time spent by the repairman there will be 3 hours so the correct answer is option D.

Answer:
(0.0757;0.1403)
Step-by-step explanation:
1) Data given and notation
Republicans =115
Democrats=331
Independents=54
Total= n= 115+331+54=500

Confidence=0.98=98%
2) Formula to use
The population proportion have the following distribution

The confidence interval for the population proportion is given by this formula

We have the proportion of independents calculated

We can calculate 
And we can find
, with this value we can find the critical value
using the normal distribution table, excel or a calculator.
On this case 
3) Calculating the interval
And now we can calculate the interval:


So the 98% confidence interval for this case would be:
(0.0757;0.1403)
