Answer:
Yes.
Step-by-step explanation:
A whole number is a number greater than or equal to zero that does not have any fractions and/or cannot be written with a fractional component. It can also be defined as an integer, though it should be noted that integers include negative numbers. 3, 5, 14, 2, and 0 are all whole numbers and are also all integers. 1.5, 16.32, and -4.598 are not whole numbers and are thus not integers.

Step-by-step explanation:
Point M is on line segment \overline{LN} LN . Given LN=3x+3,LN=3x+3, LM=4x,LM=4x, and MN=2x,MN=2x, determine the numerical length of \overline{MN}. MN .
Answer:
2 units.
Step-by-step explanation:
It is given that point M is on line segment LN. So,
[tex]LN=LM+MN[/tex] (Segment addition property)
The given values are LN=3x+3, LM=4x, and MN=2x. Substitute these values in the above formula.
[tex]3x+3=4x+2x[/tex]
[tex]3x+3=6x[/tex]
Subtract 3x from both sides.
[tex]3x+3-3x=6x-3x[/tex]
[tex]3=3x[/tex]
Divide both sides by 3.
[tex]1=x[/tex]
[tex]x=1[/tex]
The value of x is 1.
Now,
[tex]MN=2x=2(1)=2[/tex]
Therefore, length of MN is 2 units.

Oscar owns his own towing and auto repair service. He charges $45 for towing and $20 per hour, h, for labor. There is an additional charge for parts, p. Oscar uses this formula to determine the total cost, C, for towing and repairing a car. C = 45 + 20h + p What is the total cost, C, to tow and repair a car that requires four hours of labor and $109 worth of parts?
Answer:
24,28-11 that the answer
Step-by-step explanation:
Total cost C =$229 to tow and repair a car that requires 4hours of labor and $109 worth of parts.
What is total cost?"Total cost is defined as the sum of all the expenses which is required to produce a product."
According to the question,
C=total cost,
h= hour of labor
p = additional charges for parts
Total cost given as
C= 45 +20h + p
h = 4hour
p = $109
Substitute the value in the total cost we get,
C = 45+20(4) +109
=$229
Hence, total cost C =$229 to tow and repair a car that requires 4hours of labor and $109 worth of parts.

There are two numbers which add up to 29. If one number is 1 more than the other, find the two numbers.
The required smaller number is 14, and the larger number is one more than that, or 15.
What are equation models?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Here,
Let's call the smaller number x. Then the larger number is x + 1, because we know it is one more than the smaller number. We can set up an equation based on the fact that the two numbers add up to 29,
x + (x + 1) = 29
Simplifying this equation, we get:
2x + 1 = 29
Subtracting 1 from both sides, we get:
2x = 28
Dividing both sides by 2, we get:
x = 14
So the smaller number is 14, and the larger number is one more than that, or 15.
To check, we can add the two numbers together:
14 + 15 = 29

In the blank next to the distribution shape, type YES if is most often appropriate to use the mean, or NO if it is not.
1.Bell-shaped
2.Bi-model
3.Skewed
4.Symmetric
5.Uniform
=======================================
Explanations:
A bell shaped curve is symmetric, meaning one half is a mirror copy of the other half. The mean, median and mode are both at the same value: at the center (which is where the peak is located). A bimodal curve is one where it has two peaks. This is because it has 2 modes. Both peaks are the same height. If one height was taller, then you'd only have 1 mode. The mean wouldn't be as useful because we'd lose information about the two different modes. The mean would be somewhere in between the two peaks, where not much data points reside. A skewed distribution is one where the tail is pulled from the main group/cluster. This pulls on the mean to be distorted from the center. If the tail is pulled to the right (right-skewed or positively skewed) then the mean is larger than it should be. If the tail is pulled to the left (left-skewed or negatively skewed) then the mean is smaller than it should be. It's better to use the median in this case. Example: home prices where large mansions are large outliers to make the mean larger than it should be, so the median home price is used instead.As discussed in part 1 above, the mean is useful here. A bell shaped curve is one type of symmetric curve, but there are infinitely many other kinds of symmetric curves possible. All that matters is that one side is reflected over the vertical center line to get the other half.A uniform distribution is symmetric. If the left and right endpoints are p and q, then the mean (p+q)/2 is the center and it is useful.Great questions! Now, I'll tell you:

Norris currently has an account balance of $3,703.05. He opened the account 25 years ago with a deposit of $1,725.95. If the interest compounds monthly, what is the interest rate on the account? (3 points)
Answer:
R = 3.057% per year
Step-by-step explanation:
This is a compound interest question
From the question, we have the following information
P = Principal = $1,725.95.
A = Amount after 25 years = $3,703.05
T = Time = 25 years
n = Compounding frequency = compounded monthly = 12
r = interest rate = ???
The formula to calculate the interest rate in a compound interest question =
r = n[(A/P)^1/nt - 1]
r = 12[($3,703.05/$1,725.95)^1/12× 25 - 1]
r = 3.057%
Therefore, the interest rate on the account is 3.057%
Ava wants to figure out the average speed she is driving. She starts checking her car’s clock at mile marker 0. It takes her 4 minutes to reach mile marker 3. When she reaches mile marker 6, she notes that 8 minutes total have passed since mile marker 0. What is the average speed of the car in miles per minute?
Answer:
4 minutes = mile mark 3
8 minutes = mile mark 6
the constant of proportionality is both 3/4 so the answer is 3/4 miles per minute
