Mr. Jones charged Roberta $32 for parts and $15 per hour for labor to repair her bicycle. He spent 3 hours repairing her bike. Which expression would be used to correctly calculate the amount Roberta owes him?
Answer:
The expression T = 15*3 + 32 could be used to correctly calculate the amount Roberta owes Mr. Jones
Step-by-step explanation:
Given that:
Amount charged for parts = $32
Per hour labor = $15
Time spent on repairing = 3 hours
Total amount = Per hour labor * Number of hours + Amount of parts
T = 15*3 + 32
Hence,
The expression T = 15*3 + 32 could be used to correctly calculate the amount Roberta owes Mr. Jones

A. The y-intercept of Function 1 is the same as that of Function 2.
B. The rates of change of both functions are positive.
C. The rate of change of Function 1 is the same as that of Function 2.
D. The y-intercept of Function 1 is greater than that of Function 2.
Answer:
C. The rate of change of Function 1 is the same as Function 2.
Step-by-step explanation:
The rate of change in an equation is the slope. In this case, function 1's slope is 1/2 and in function 2 - y=1/2x+3, the slope, or rate of change, is also 1/2. This means that statement C. is correct. Hope this helps :) Good luck!!

Answer:
f1 ( x ) valid pdf . f2 ( x ) is invalid pdf
k = 1 / 18 , i ) 0.6133 , ii ) 0.84792
Step-by-step explanation:
Solution:-
A) The two pdfs ( f1 ( x ) and f2 ( x ) ) are given as follows:
- To check the legitimacy of a continuous probability density function the area under the curve over the domain must be equal to 1. In other words the following:
- We will perform integration of each given pdf as follows:
Answer: f1 ( x ) is a valid pdf; however, f2 ( x ) is not a valid pdf.
B)
- A random variable ( X ) denotes the resistance of a randomly chosen resistor, and the pdf is given as follows:
if 8 ≤ x ≤ 10
0 otherwise.
- To determine the value of ( k ) we will impose the condition of validity of a probability function as follows:
- Evaluate the integral as follows:
... Answer
- To determine the CDF of the given probability distribution we will integrate the pdf from the initial point ( 8 ) to a respective value ( x ) as follows:
To determine the probability p ( 8.6 ≤ x ≤ 9.8 ) we will utilize the cdf as follows:
p ( 8.6 ≤ x ≤ 9.8 ) = F ( 9.8 ) - F ( 8.6 )
p ( 8.6 ≤ x ≤ 9.8 ) =
ii) To determine the conditional probability we will utilize the basic formula as follows:
p ( x ≤ 9.8 | x ≥ 8.6 ) = p ( 8.6 ≤ x ≤ 9.8 ) / p ( x ≥ 8.6 )
p ( x ≤ 9.8 | x ≥ 8.6 ) = 0.61333 / [ 1 - p ( x ≤ 8.6 ) ]
p ( x ≤ 9.8 | x ≥ 8.6 ) = 0.61333 / [ 1 - 0.27666 ]
p ( x ≤ 9.8 | x ≥ 8.6 ) = 0.61333 / [ 0.72333 ]
p ( x ≤ 9.8 | x ≥ 8.6 ) = 0.84792 ... answer
Hope it helps! ;)

A sample with a sample proportion of 0.4 and which of the following sizes
will produce the widest 95% confidence interval when estimating the
population parameter?
A. 90
B. 60
C. 75
D. 120
The size 60 will produce the widest 95% confidence interval when estimating the population parameter.
What is confidence interval?'A confidence interval is the mean of your estimate plus and minus the variation in that estimate.'
According to the given problem,
IN a sample with n number of people surveyed with a probability of a success of [tex]\pi[/tex] and a confidence level of 1-α , we have the following confidence interval of proportions.
[tex]\pi[/tex] ± [tex]z\sqrt{\frac{\pi (1-\pi )}{n} }[/tex]
In which, z is the z score that has a p value of 1 -(α/2)
The margin of error is:
M = z [tex]\sqrt{\frac{\pi (1-\pi )}{n} }[/tex]
The higher the margin of error, the wider an interval is.
As the sample size increases, the margin of error decreases. If we want, the widest possible interval, we should select the smallest possible confidence interval.
Hence, we can conclude that 60 is the correct answer.

Find the inverse function (on the given interval, if specified)
f(x) = x² + 1 for x 20
Find the inverse function.
f'(x)= for x2
Step-by-step explanation:
f(x) = x² + 1, where x >= 0.
Let y be f(x).
=> y = x² + 1
=> x² = y - 1
=> x = √(y - 1) because x is non-negative.
Hence f^-1(x) = √(x - 1), where x >= 1.

Step-by-step explanation:
-3x+8+5x=-4
Subtract 8 from both sides and add
2x=-12
X=-6
Step 1: Simplify both sides of the equation.
−3x+8+5x=−4
(−3x+5x)+(8)=−4(Combine Like Terms)
2x+8=−4

Step-by-step explanation:

The cost of renting a canoe to use on River Y costs $38. The cost of renting a canoe to use on River Z costs $4 per hour plus a $14 deposit. The total cost, c, of renting a canoe on either river for n hours can be represented by an equation. Write and graph a system to find how many hours you have to rent a canoe for the cost to be the same on both rivers.
Answer:
see the attachment
Step-by-step explanation:
The cost for River Y is a constant (not dependent upon hours), so is c = 41.
The cost for River Z is the sum of the deposit and the hourly cost, so is ...
c = 13+4n
These equations and their graphs are shown in the attachment. The graphs cross where n=7, indicating you have to rent a canoe for 7 hours for the cost to be the same on both rivers.
