Kendall recently received a job offer which required him to move his house full of furniture across the country from Columbia, S

outh Carolina, to Riverside, California. To manage his moving expenses, Kendall kept track of the amount of gasoline used by the moving truck he rented. The truck used 109 gallons of gas to drive 1,092 miles from Columbia to Des Moines, Iowa. On the next leg of the drive, the truck used 67 gallons of gas to drive 671 miles from Des Moines to Denver, Colorado. Finally, he used 99 gallons of gas to drive 985 miles from Denver to Riverside, California. Using x to represent the number of miles and y to represent the number of gallons, create a table of values to represent this relation.

Answer:

Step-by-step explanation:

A table of values is generally used when there are few values of the independent variable "x" and their corresponding values of the dependent variable "y".

x = Number of miles (Independent variable)

y = Number of gallons (dependent variable)

The table of values can be represented as follows:

<u>                      x ------------------- y ------- Relationship (x / y) </u>

                 1,092 ------------ 109 --------- 10.02

                   671 -------------- 67 ---------- 10.02

                   985 ------------- 99 ----------- 9.95

              --------------------------------------------------

Total          2,748 ----------- 275 ---------- 9.99

Hope this helps!

Step-by-step explanation:

From what we know dinner is $83 and the tax is %7.5

Step 1) Round the %7.5 to %8

Step 2) Turn the %8 into -> 0.08

Step 3) Multiply 0.08 by 83 which is 6.64

Step 4) Add 6.64 with 83

Answer) Together the full price of the meal is $89.64

An electronic system has each of two different types of components in joint operation. Let X and Y denote the lengths of life, i
AURORKA [14]

Answer:

a

The average cost is E(C) = 66

b

The standard deviation of  cost is  \sigma  = 9.798

Step-by-step explanation:

From the question we are told that

          E(X) =  4

          E(Y) =  2

          E(X^2) =  24

           E(Y^2) =  8

The cost of replacing the two component is  C =  50 + 2 X + 4 Y

The variance   of X is mathematically represented as

           V(X) =  E(X^2) - [E(X)]^2

Substituting values  

              V[X] =  24 - 4^2

               V[X] =8

The variance  of Y is mathematically represented as

           V(Y) =  E(Y^2) - [E(Y)]^2

Substituting values  

              V[Y] =  8 - 2^2

               V[X] =4

The average of  replacing the two component is  

        E(C) =  2 * E(X)  + 4* E(Y)

substituting value

         E(C) =  50 + 2 * (4)  + 4* (2)

         E(C) = 66

The variance  of replacing the two component is  

        V(C) = V(50 + 2X +4Y)      Note: The variance of constant is zero

                                                                  and X and  Y are independent  

=>      V(C) =  2^2 * V(X) + 4^2 * V(Y)

substituting values

=>       V(C) =  4 * 8 +  16 * 4        

=>         V(C) =  32 + 64

=>         V(C) = 96

The standard deviation is

         \sigma  =  \sqrt{V(C)}  

substituting values

           \sigma  =  \sqrt{96}

           \sigma  = 9.798

A rope is stretched from the top of a 60 feet pole to a point on the ground 11 feet away from the base of the pole. What is the
Black_prince [1.1K]
You'd use the equation a^2 + b^2 = c^2        (**** ^2 means squared****)

a = 60

b = 11

c = ? 
 
60^2 + 11^2 = c^2 

3600 + 121 = c^2

3721 = c^2 

then just square root 3721 and c^2 

c = 61 feet
