Josh rented a truck for one day there was a base fee fee of $12 and there was additional charge of 8 cents for each mile driven the total cost (c) for driving x miles is given by the following function
C(x)=12.00+0.08x
what is the total rental cost if Josh drive 20 miles?
Answers
Answer:
$13.60
Step-by-step explanation:
You want to evaluate the rental cost function C(x) = 12.00 +0.08x for x = 20.
EvaluationPut the value for x where x is in the cost function and do the arithmetic.
C(x) = 12.00 +0.08x
C(20) = 12.00 +0.08·20 = 12.00 +1.60
C(20) = 13.60
The total rental cost if Josh drives 20 miles is $13.60.

When Mr Norman turns 58, he will be two years older than twice the age his daughter will turn in January. How old is Nicole now?
How do I write down the equation?
Answers
Step-by-step explanation:
When Mr Norman turns 58, he will be two years older than twice the age his daughter will turn in January. How old is Nicole now?
equation: 58 = 2d + 2
58 = 2d + 2
subtract 2 from both sides:
56 = 2d
divide both sides by 2:
d = 28 , so his daughter is 28 years old.

For the given modeled of equation ý = 0.66x + 33.3 the interpretation of the residual is given option D. 1.3 The regression line underpredicts the students class average.
As given in the question,
Equation to represents the grade of a students based on class attendance is given by :
ý = 0.66x + 33.3
Where ý is the grade of students in form of percentage.
And 'x' is the students attendance
Actual percentage = 94% when x = 90
Predicted percentage is,
ý = 0.66(90) + 33.3
= 92.7%
Residual = Actual - Predicted
= 94% - 92.7%
= 1.3
Actual > Predicted
Therefore, from the given equation the interpretation of the residual is given by Option D. 1.3 student's class average was underpredicted by the regression line.

3. The equation of the linear function is given as follows: y = -2.5x + 80.
How to obtain the distance traveled by the car each second?This distance is the rate of change of the output variable relative to the input variable of the linear function, hence it is the slope of the linear function.
Two points on the graph are given as follows:
(0,0) and (1,3).
Then the slope is calculated as the change in the output divided by the change in the input, as follows:
m = (3 - 0)/(1 - 0) = 3.
Meaning that option C is correct.

b = 80.
When x increases by 8, y decayed by 20, hence the slope is calculated as follows:
m = -20/8 = -2.5.

the mean score on a college placement exam is 500 with a standard deviation of 100. ninety-five percent of the test takers score below what value?
Answers
The value for which test score is below 95% percent for the given mean and standard deviation on a college placement is equal to 696.
As given in the question,
Given : 95% of the test takers score are below z.
z-score is given by,
z=(x-μ)/σ
Mean of the score 'μ' = 500
Standard deviation of the score ' σ' = 100
Z = 95%
= 0.95
P(z<Z) = 1-0.95
= 0.05
The value of z which corresponds to 0.05 in the table is equal to 1.96.
Substitute all the values we get,
z=(x-μ)/σ
⇒1.96 = ( x - 500 ) / 100
Multiply by 100 both the sides we get,
⇒ 196 = ( x - 500 )
⇒ x = 696
Therefore, the value for which test score is below 95% percent for the given mean and standard deviation is equal to 696.

The ratio of yellow marbles to purple marbles was 13 to 4. If there were 102 marbles in the bag, how many were yellow marbles?
Answers
The number of yellow marbles based on the given ratio will be 78.
What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
Suppose, the number of yellow marbles is Y while purple marbles are P.
As per the given,
The ratio Y/P = 13/4
Total Y + P = 102
(13/4)P + P = 102
13P + 4P = 408
17P = 408
P = 24
And, Y = 102 - 24 = 78

Answer: y=-5x-1. I need someone to tell me what translating equations is and how to get there.
Answers
The equation after the transformation is y = -5x - 1
How to determine the equation after the transformation?From the question, we have the following parameters that can be used in our computation:
Equation: 5x - y = 15
Make y the subject
So, we have
y = 5x + 15
The rule of reflection across the y-axis is
(x, y) = (-x, y)
So, we have the following equation
y = -5x + 15
The rule of translation by (3 -1) is
(x, y) = (x + 3, y - 1)
So, we have the following equation
y = -5(x + 3) + 15 - 1
Expand
y = -5x - 15 + 15 - 1
So, we have
y = -5x - 1
Hence, the equation is y = -5x - 1
