The cost per hour for the labor will be $75
Total amount charged = $530.50
Amount charged for parts = $193
Number of hours used = 4.5 hours
Let the amount charged per hour = x
Therefore, the equation to solve the question will be:
193 + 4.5(x) = 530.50
193 + 4.5x = 530.30
Collect like terms
4.5x = 530.50 - 193
4.5x = 337.50
Divide both side by 4.5
4.5x/4.5 = 337.50/4.5
x = 75.
The cost of labor per hour is $75

An NBA trainer wants to know if his stretching routine is helping the players on his team jump higher. He records the average height jumped for 8 players before completing his stretching routine, and then again after they have stretched. What is the parameter? Group of answer choices dbar = the true sample mean difference in jump height mu_d = the true sample mean difference in jump height dbar = the true population mean difference in jump height mu_d = the true population mean difference in jump height
Answer:
a. mu_d = the true population mean difference in jump height
Step-by-step explanation:
In statistical parlance, observations used for a study could either be randomly chosen points or members of a large group or population, this small chosen observation obtained from a larger group is called the sample, the statistical measures or characteristic of such group is called statistic; while statistical characteristic, computations or measurement of the entire group of observations is called the parameter.
Mean of sample are usually represented with a bar sign on top such as (xbar) ; while mean of a population is represented as μ.

Ken earned $128 from his part-time job this summer. He spent 25% of his money on games. He is going to donate 1/6 of the remaining money to charity. How much will the charity receive?
A) $15
B) $16
C) $32
D) $80
Please explain how to do it also
Answer:
B) $16
Step-by-step explanation:
Alright so first you want to take the total amount of money made :
$128
Next you want to find 25% of this number (or 1/4) and subtract it from the total.
So :
128 / 4 = 32
So now we take 128 and subtract 32. (32 = 1/4 or 25% of 128)
128 - 32 = 96
Ken now has $96 left over after spending money on games.
So now that we have this number we need to find 1/6 of it because he took 1/6 of the money after he bought games and put it towards charity.
So :
96 / 6 = 16
16 is equal to 1/6 of his leftover money after games and is the amount the charity received.
B) $16
I hope this helps! :)
If you are confused or have any questions please comment or dm and I would be happy to help.
Also change the pfp FeelsGoodMan
Answer:
B) $16
Step-by-step explanation:
1. First let's find how much he spent on games. Multiply 0.25 to 188. 0.25 x 128 = 32.
2. Now subtract that amount from the original $128. 128 - 32. = 96.
3. Then, multiply 1/6 from 96. 1/6 x 96 = 16. This $16 is the amount the charity will receive.
find the value of each variable in the parallelogram
Answer:
1. x = 15°
2. y = 12
Step-by-step explanation:
1. Determination of the value of x.
(5x – 5) + 110 = 180 (Adjacent angles add up to 180)
5x – 5 + 110 = 180
5x + 105 = 180
Collect like terms
5x = 180 – 105
5x = 75
Divide both side by 5
x = 75/5
x = 15°
2. Determination of the value of y.
3y – 4 = 2y + 8 (opposite sides are equal)
3y – 4 = 2y + 8
Collect like terms
3y – 2y = 8 + 4
y = 12

At a local fitness center, members pay a $10 membership fee and $4 for each aerobics class. Nonmembers pay $6 for each aerobics class. For what number of aerobics classes will the cost for members and nonmembers be the same?
Answer:
5 classes
Step-by-step explanation:
Let x represent the number of aerobics classes
Create an equation that sets the member and nonmember prices equal to each other, then solve for x:
4x + 10 = 6x
10 = 2x
5 = x
So, after 5 aerobics classes, the costs will be the same.
how do I find 16% of 575
Answer:
92
Step-by-step explanation:
The easiest way for me to find any percentage of a number is to find what 1% is and then multiply by the % amount. So to answer this question I would do 575/100 which is 5.75 and this is 1% then multiply 5.75 by 16 to get 92 so a 16% of 575 is 92. (Double check to make sure I'm correct)
determine the relationship between the measures of the given angles
∠PTV > ∠VPT. This is because the angle opposite to the larger side is greater.
What are angles and dihedral angles? What is equation modelling? In Euclidean geometry, an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle. Angles formed by two rays lie in the plane that contains the rays. Angles are also formed by the intersection of two planes. These are called dihedral angles.Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.Given is a 2 - D image as shown in the question.
It can be concluded that ∠PTV > ∠VPT. This is because the angle opposite to the larger side is greater.
Therefore, ∠PTV > ∠VPT. This is because the angle opposite to the larger side is greater.

Let the random variable X be equally likely to assume any of the values 1/14, 1/7, or 3/14. Determine the mean and variance of X. The mean is Enter your answer; The mean is 1/7 [Give exact answer in form of fraction.] The variance is Enter your answer; The variance is 0.1190 [Round your answer to four decimal places (e.g. 98.7654).]
Answer:
1/7 ;
0.0034
Step-by-step explanation:
Given that:
X = 1/14, 1/7, 3/14
n = number of observations = 3
Since, probability of X is equally likely ;
P(X) = Σp(x) = 1 ; p(x) = 1/n = 1/3
The mean, m ;
Σx*p(x) = (1/3 * 1/14) + (1/3 * 1/7) + (1/3 * 3/14)
= 1/42 + 1/21 + 3/42
= (1 + 2 + 3) / 42
= 6 / 42
= 1/7
The variance :
Σx²*p(x) - m²
((1/3) * (1/14)^2) + ((1/3) * (1/7)^2) + ((1/3) * (3/14)^2) - (1/7)^2
= 0.0238095 - 0.0204081
= 0.0034014

What is 49% in a decimal
Answer:
0.49
Step-by-step explanation:
Answer:
Step-by-step explanation:
49% = 0.49 in decimal form. Percent means 'per 100'. So, 49% means 49 per 100 or simply 49/100. If you divide 49 by 100, you'll get 0.49 (a decimal number).

slope (m): ?
coordinates: ?
Answer:
Your slope would be: -5
Step-by-step explanation:
First we need to format it into a linear equation which is: y= mx+b
y+5= (x+3)
and than minus 5 on each side to get:
y=(x+3)-5
than use distributive property to get:
y= -5x+-15
your slope would be:
-5
and than you can get any coordinates from the line if you graph the line on the site "desmos" so just use that site :)

I'm fishing. The probability of catching a fish on each cast of my rod (each attempt) is 0.23. Each attempt is independent. If I made 12 attempts and wanted to find the probability that I caught 2 or fewer fish, is this a geometric or binomial situation
Answer:
This is a binomial situation.
Step-by-step explanation:
For each attempt, there are only two possible outcomes. Either you catch a fish, or you do not. This can mean that either we have a binomial distribution, or a geometric.
However, each attempt is independent, which means that in each attempt, the probability of catching a fish is the same, and that this is a binomial situation.
The probability of catching a fish on each cast of my rod is a binomial distribution.
From the question, we can see that there are two possibilities which are whether you catch a fish or not. This gives two possibilities showing that we have a binomial distribution.
However, each attempt is independent, which means that one attempt does not affect the other. This is therefore a binomial situation.
Hence the probability of catching a fish on each cast of my rod is a binomial distribution.
