Answer: sum of the prices divided by 7
Step-by-step explanation:
Formula for mean: [tex]\text{Mean }=\dfrac{\text{Sum of observations}}{\text{Number of observations}}[/tex]
Given: The prices of T-shirts at a clothing store: {8, 10, 10, 12, 15, 15, 18}
Here number of observations = 7
According to the formula of mean,
The statement that describes the mean of this set = sum of the prices divided by 7
Hence, the correct statement : sum of the prices divided by 7

which graph represents the function y = 2x - 4
Answer:
I will change my awnser when you tell me but what are the awnser choices
Step-by-step explanation:
The graph which represents the function y = 2x - 4 is shown below.
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) (the dependent variable). In mathematics and the physical sciences, functions are indispensable for formulating physical relationships.
Linear function is a function whose graph is a straight line
We are given that;
y = 2x - 4
Now,
To find four points of y = 2x - 4, we can choose any four values of x and plug them into the equation to find the corresponding values of y. For example, if we choose x = -2, 0, 1, and 2, we get:
When x = -2, y = 2(-2) - 4 = -8 - 4 = -12. So (-2,-12) is a point on the line.
When x = 0, y = 2(0) - 4 = 0 - 4 = -4. So (0,-4) is a point on the line.
When x = 1, y = 2(1) - 4 = 2 - 4 = -2. So (1,-2) is a point on the line.
When x = 2, y = 2(2) - 4 = 4 - 4 = 0. So (2,0) is a point on the line.
Therefore, by the given function answer will be shown below.

15 less than 2 times a number is the same as 7 more than half of the number. what is the number?
Answer:
x = 14 and 2/3
Step-by-step explanation:
Make an equation where x is the number.
2x - 15 = 7 + 1/2x
Then, solve the equation.
multiply both sides by 2 to get rid of the fraction
4x - 30 = 14 + x
subtract x from both sides
3x - 30 = 14
add 30 to both sides
3x = 44
divide both sides by 3
x = 14 and 2/3

The correct pairs of equivalent expressions are:
(5 + 2b)+(2b + 3/2) <--> 4b + 13/2
(-10 + b)+(7b - 5) <---> 8b - 15

What is an equation of the line that passes through the points (-7, -5)(−7,−5) and (-7, -2)(−7,−2)?
Given:
A line passes through two points (-7, -5) and (-7, -2).
To find:
The equation of the line.
Solution:
If a line passes through two points, then the slope of the line is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
The line passes through two points (-7, -5) and (-7, -2). So, the equation of the line is
[tex]m=\dfrac{-2-(-5)}{-7-(-7)}[/tex]
[tex]m=\dfrac{-2+5}{-7+7}[/tex]
[tex]m=\dfrac{3}{0}[/tex]
[tex]m=\infty[/tex]
Here, slope is ∞. It means it is a vertical line of the form [tex]x=a[/tex], where a is constant.
It the given points x-coordinates are same, i.e., -7. So, equation of the line is
[tex]x=-7[/tex]
Therefore, the equation of the line is [tex]x=-7[/tex].
Find the area of each shaded region. give your answer as a completely simplified exact value in terms of pi. (no approximates)
Answer:
52[tex]\pi[/tex]
Step-by-step explanation:
We see that the radius of the big circle is 8m, and we see that the it is also the diameter of the second smallest circle. We also see that this diameter is split into two equal parts, and since the entire length is 8, each part will be 4. So what we need to do is find the area of each circle.
First we can start by finding the area of the smallest circle. The radius of this circle will be 4/2, 2. So the area of this circle will be [tex]\pi[/tex][tex]r^{2}[/tex], and in this case 4[tex]\pi[/tex].
Then we need to find the area of the bigger shaded portion, which will be the area of the big circle, minus the area of the smaller white circle.
First, lets find the are of the big circle, which again, will be [tex]\pi[/tex][tex]r^{2}[/tex]. This time, we plug in a radius of 8, and we get 64[tex]\pi[/tex].
Next we find the area of the smaller white circle, again [tex]\pi[/tex][tex]r^{2}[/tex]. We use a radius of 4 this time, giving us an area of 16[tex]\pi[/tex].
Now we subtract the two values we found previously to find the area of the just the bigger shaded portion. That value will be 64[tex]\pi[/tex]-16[tex]\pi[/tex], which is 48[tex]\pi[/tex]
We then take 48[tex]\pi[/tex], and we add the small shaded portion, which had an area of 4[tex]\pi[/tex], and we add them, giving us a total of 52[tex]\pi[/tex].
