In a sample of n = 6, five individuals all have scores of x = 10 and the sixth person has a score of x = 16. what is the mean for this sample?
The mean of samples 10, 10, 10, 10, 10, and 16 will be 11.
What is Mean?The mean is the straightforward meaning of the normal of a lot of numbers. In measurements, one of the markers of focal propensity is the mean. The normal is alluded to as the number-crunching mean. It's the proportion of the number of genuine perceptions to the absolute number of perceptions.
In a sample of n = 6, five individuals all have scores of x = 10 and the sixth person has a score of x = 16.
Then the data set will be given below.
10, 10, 10, 10, 10, 16
Then the mean of the data set will be
Mean = (10 + 10 + 10 + 10 + 10 + 16) / 6
Mean = 66/6
Mean = 11
Thus, the mean of the sample will be 11.

2x+15=25 find for x
Answer:
x= 5
Step-by-step explanation:
2x+ 15=25
-15 -15
2x= 10
/2 /2
x=5
Answer:
x = 5
Step-by-step explanation:
2x + 15 = 25
2x + 15 - 15 = 25 - 15 (subtract 15 from both sides)
2x = 10
2x/2 = 10/2 (divide by 2 on both sides)
x = 5
find the perimeter of the polygon with vertices U (-2,4) V (3,4) and W (3,-4)
So the perimeter of the polygon with vertices U (-2,4) V (3,4) and W (3,-4) is Perimeter = 22.434
Perimeter of any close shape is the total length of the boundary of any closed shape.
We have been given vertices of polygon that are U (-2,4) V (3,4) and W (3,-4)
To find the perimeter we need to find the length of all three sides, and we do that by finding the distance between the points that form the sides:
The formula for the distance between two points is:
[tex]$d=\sqrt{\left(x_1-x_2\right)^2+\left(y_1-y_2\right)^2}$[/tex]
side UV:
[tex]$U V=\sqrt{(-2-3)^2+(4-4)^2}=5$[/tex]
side VW:
[tex]$V W=\sqrt{(3-3)^2+(4-(-4))^2}=8$[/tex]
side UW:
[tex]$U W=\sqrt{(-2-3)^2+(4-(-4))^2}=9.434$[/tex]
So the perimeter is:
P=UV+VW+UW
[tex]$P=5+8+9.434=22.434$[/tex]
So the perimeter is: 22.434

How do I find the value of x that make lines u and v parallel
=======================================================
Explanation:
The square marker in the top left corner tells us we have a 90 degree angle. The 8x+10 must also be 90 degrees for lines u and v to be parallel. Refer to the alternate exterior angle theorem. Ignore the diagonal lines. Your teacher likely put them there as a distraction.
8x+10 = 90
8x = 90-10
8x = 80
x = 80/8
x = 10
Write a function rule for the table
The function rule for the table is y = 25/4 x
Equation of a linear functionThe standard expression for a linear function is expressed as y =mx + b
where
m is the slope
b is the y-intercept
Using the coordinate points (4, 25.00) and (8, 50.0)
Determine the slope
Slope = 50-25/8-4
Slope = 25/4
Determine the y-intercept
50 = 25/4(8) + b
50 = 25(2) + b
50 = 50 + b
b = 0
Hence the function rule for the table is y = 25/4 x

Mel makes arm bracelets . she is making one for each arm of her six friends . How
many should she make
Mel should make 12 bracelets.
Here, we are given that Mel makes arm bracelets.
She is making a bracelet for each arm of her 6 friends.
We know that a humans by default have 2 arms each.
We will assume that all of her 6 friends have 2 arms each.
Thus, 6 of her friends will get 2 bracelets each, one for each arm.
This means that the total number of bracelets Mel should make will be given by-
2 + 2 + 2 + 2 + 2 + 2
or we can also write this as
2 × 6
6 times 2 is equal to 12.

What is a linear function?A linear function is modeled by the following rule:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, the change in y divided by the change in x.b is the y-intercept, which is the the value of y when the function crosses the x-axis, that is, when x = 0.Another feature of linear functions is uniform behavior, as they are either increasing or decreasing over the entire domain, there are no changes from increasing to decreasing.
Heights increase or decrease over the domain, hence they are not linear, while the area of the square is quadratic, as A = s².
One hour has 3600 seconds, hence the number of seconds in a number of hours is modeled by the following linear function:

New, larger bottle of shampoo contains 20 ounces. the bottle says you get 33% more than the amount in the original bottle. how many ounces of shampoo were in the original bottle?
Amount of shampoo in the original bottle is 15.0376 ounces.
Larger bottle of shampoo contains = 20 ounces
Let, amount of shampoo in the original bottle = x ounces
33% of amount of shampoo in the original bottle = ((33x)/100)
According to the question, amount of shampoo in the larger bottle is 33% more of amount of shampoo in the original bottle. So, mathematically we can write
20 = x + ((33x)/100)
⇒ 20 = x + 0.33x
⇒ 20 = 1.33 x
⇒ x = 20/1.33
⇒ x = 15.0376
Amount of shampoo in the original bottle is 15.0376 ounces.

Which of the following inequalities would be graphed with an open circle?
3(x - 2) < 18 and h + 6 > -3h + 12 would be graphed with an open circle.
Open circle is a term used for numbers that are less than (<) or greater than (>). On the other hand, Closed circle is used for numbers that are less than or equal to (≤ ) and greater than or equal to (≥).
Here, we are given four inequalities, let us check them one by one-
A. h + 6 > -3h + 12
⇒ 4h > 6
or h > 3/2
Here, we see that there is no equality sign, this means that 3/2 won't be included and hence h + 6 > -3h + 12 would be an open circle inequality.
B. 7 ≥ d/3
⇒ d ≤ 21
Here, we can clearly see the equality sign which means that 21 will be included. Hence, 7 ≥ d/3 would not be graphed with an open circle.
C. 3(x - 2) < 18
x - 2 < 6
x < 8
Here, we see that there is no equality sign, this means that 8 won't be included and hence 3(x - 2) < 18 would be graphed with an open circle.
D. 2y ≤ 14
y ≤ 7
Here, we can clearly see the equality sign which means that 7 will be included. Hence, 2y ≤ 14 would not be graphed with an open circle.

(Point-Slope Equation)
any detailed answer for this??
Answer: y = 8
Step-by-step explanation:
Point-slope form is written as y - [tex]y_1[/tex] = m(x - [tex]x_1[/tex]) where m is the slope and ([tex]x_1[/tex] , [tex]y_1[/tex]) are points on the line.
First, we need to find the slope. This can be found with change in y over change in x:
[tex]\displaystyle \frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
[tex]\displaystyle \frac{8-8}{-4--4}=\frac{0}{-4+4}=\frac{0}{0}=[/tex] undefined
Now, we will plug this undefined slope (0) into the equation below. Anything times 0 is 0, so no matter what (x - [tex]x_1[/tex]) is, the right side of the equation will always be 0.
y - [tex]y_1[/tex] = m(x - [tex]x_1[/tex])
y - [tex]y_1[/tex] = (0)(x - [tex]x_1[/tex]) ➜ y - [tex]y_1[/tex] = 0
Lastly, we will take the y-value of 8 and plug it into the equation and simplify.
y - [tex]y_1[/tex] = 0 ➜ y - (8) = 0 ➜ + 8 (y - 8) = (0) + 8
y = 8

Given a function f(x) = m/x-1 + n, where f(-2) = 1 and f(4) = 3. Find the values of m and n
We get the values of m as 1 and n as 0.
We are given a function:
f(x) = m / (x - 1) + n
We are also given that:
f (-2) = 1 and f (4) = 3
We have to find the value of m and n.
f (-2) = m (2 - 1) + n
1 = m + n
n = 1 - m
f (4) = m / (4 - 1) + n
3 = 3 m + n
3 = 3 m + 1 - m
3 = 2 m + 1
2 m = 3 - 1
2 m = 2
m = 2 / 2
m = 1
m + n = 1
1 + n = 1
n = 0.
