Locksmith Larry charges $90 for a house call plus $20 per hour. Locksmith Barry charges $50 for a house call plus $30 per hour. Write a one-variable equation for the charges of locksmith Larry
Answer:
Barry: g(x) = 50 + 30x
Larry: f(x) = 90 + 20x
If Locksmith Larry charges $90 for a house call plus $20 per hour. Locksmith Barry charges $50 for a house call plus $30 per hour. Then f(x)=90+20x is one-variable equation for the charges of locksmith Larry
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given,
Locksmith Larry charges $90 for a house call plus $20 per hour
f(x) represents this situation
f(x) equal to ninety plus twenty times of x
f(x)=90+20x
Locksmith Barry charges $50 for a house call plus $30 per hour
g(x) represents this situation
g(x) equal to fifty plus thirty times of x
g(x)=50+30x
Here x represents the number of hours
Hence f(x)=90+20x is the one-variable equation for the charges of locksmith Larry

Brett is performing a hypothesis test in which the population mean is 310 and the standard deviation is 20. His sample data has a mean of 295 and a sample size of 50. Which of the following correctly depicts the z-statistic for Brett’s data?
Answer:
-5.30
Step-by-step explanation:
The z-statistic of the Brett's data is -5.30
What is z-statistics?The formula for the test statistic depends on whether the population standard deviation (σ) is known or unknown. If σ is known, our hypothesis test is known as a z test and we use the z distribution
What is Standard deviation?The standard deviation is a measure of the amount of variation or dispersion of a set of values.
What is Mean?Mean is the average of the given numbers and is calculated by dividing the sum of given numbers by the total number of numbers.
Given,
Population Mean = 310
Standard deviation = 20
Sample data mean = 295
Sample size =50
z-statistic = (Sample data mean - Population mean) / (Standard deviation /[tex]\sqrt{sample size}[/tex])
z-statistic = [tex]\frac{295-310}{20/\sqrt{50} } =-5.30[/tex]
Hence, the z-statistic for Brett's data is -5.30

What are the domain and range of each relation?
Drag the answer into the box to match each relation.
Answer:
Please check the explanation.
Step-by-step explanation:
We know that the domain of a function is the set of input or argument values for which the function is real and defined.Thus, the domain of the first relation is: {-2, -1, 0, 2}
We also know that the range of a function is the set of values of the dependent variable for which a function is defined.Thus, the range of the first relation is: {-4, -2, 2}
Given the second relation
x y
-4 -2
-2 1
1 4
4 4
We know that the domain of a function is the set of input or argument values for which the function is real and defined.Thus,
The domain of the second relation is: {-4, -2, 1, 4}
We also know that the range of a function is the set of values of the dependent variable for which a function is defined.Thus,
The range of the second relation is: {-2, 1, 4, 4}

1/2p+2=3 1/2
Step-by-step explanation:
Answer:
[tex]\frac12p+2 = 3\frac12[/tex]
Step-by-step explanation:
The time he spends is the sum of the mandatory 2 hours and p times the half hour per puzzle. It has to end up to 3 1/2, so that's how you get the equation.
Of course, you can solve it as
[tex]p = \frac{1\frac12}{\frac12} = 3[/tex]
Find the sum that amounts to rs.3025 at 10% p.A
Answer:
P = Rs2500
Step-by-step explanation:
Given that,
Amount, A = Rs 3025
Rate, r = 10%
Let time, t = 2 years
We need to find the sum if the amount is compounded annually. Using the formula of compound interest.
[tex]A=P(1+\dfrac{r}{100})^n\\\\P(1+\dfrac{10}{100})^2=3025 \\\\P(1.21)=3025\\\\P=\dfrac{3025}{1.21}\\\\P=\text{Rs}\ 2500[/tex]
So, the sum of money is Rs 2500.

Answer:
6.67 seconds
Step-by-step explanation:
Benny = 15 - 0.5s
Juan = 10 + 0.25
Where,
s = number of seconds
Equate
15 - 0.5s = 10 + 0.25s
15 - 10 = 0.25s + 0.5s
5 = 0.75s
s = 5/0.75
= 6.66667 seconds
Approximately 6.67s
