The mean of three numbers is 4. Two of the numbers are shown below. What is the missing number? 1, 9, ?
If the mean is 4 then the missing number will be 2.
What is mean?The mean is the average of all the data values present in the data set.
Mean=sum/number
How to calculate mean?Let the missing number be x in this way mean will be
(1+9+x)/3=4
10+x=12
x=2
Hence if mean is 4 then the missing number will be 2.

Brendan ran a total of 8 miles over the course of 4 track practices.
How many track practices would it take for Brendan to run 10 miles? Solve using unit rates.
Answer:
5 track practices
Step-by-step explanation:
So if he ran 8 miles in 4 track practices, he ran 2 miles in each.
So it would take 5 track practices to do it.
Cell phone Company ABC charges a $12 start-up fee plus $0.08 per minute, x/ Cell phone Company WYZ charges $0.20 per minute, x, with no start-up fee. Which function represents the difference in cost between Company ABC and Company WYZ?
Answer:
difference of cost between two company = 12 - 0.12 x
Step-by-step explanation:
For company ABC
start up fee = $12
cost of one minute call = $0.08
if x minute call are done then cost of x call = 0.08*x = 0.08x
total cost incurred in company ABC= startup fee+ cost of x minute call = 12+0.08X
___________________________________________________
For company WYZ
start up fee = 0
cost of one minute call = $0.20
if x minute call are done then cost of x call = 0.20*x = 0.20x
total cost incurred in company WYZ plan = startup fee+ cost of x minute call = 0+0.20x = 0.20x
______________________________________________
difference of cost between two company = 12+0.08x - 0.20x
difference of cost between two company = 12 - 0.12x (Answer)

what is the point slope form of a line with slope -3 that contains the point (2,-2)
Answer:
y+2 = -3(x-2)
Step-by-step explanation:
Point slope form of an equation is
y-y1 = m(x-x1) where m is the slope and (x1,y1) is a point on the line
y - -2 = -3( x-2)
y+2 = -3(x-2)
Answer:
Y=-3x+4
Step-by-step explanation:
Please graphing and all I did was input the coordinates into the Y=mx+b form, got the b and filled in everything else. Hope this helps!

You are building a gazebo for your mom; you want it to look like the picture below.
a. Using geometry, name which quadrilaterals you see in the picture.
b. What type of quadrilateral is each side of the roof (see inset)?
c. What specific type must it be in order for each side of the roof to fit properly?
d. What is the length of the opposite leg on the side of the roof?
e. What measure is the other base angle?
f. What is the measure of the opposite angles?
Answer:
a. 1. Trapezoid
2. Rectangle
b. Trapezoid
c. Isosceles trapezoid
d. 6 feet
e. 65°
f. 115°
Step-by-step explanation:
a. The observed quadrilaterals are;
1. Trapezoid
2. Rectangle
b. Trapezoid
c. Isosceles trapezoid
d. Whereby we have an isosceles trapezoid, the leg lengths are equal. therefore since one of the leg lengths = 6 feet, the other opposite leg on the side of the roof = 6 feet
e. The base angles of an isosceles triangle are equal, therefore, the other base angle is equal to the labelled base angle or 65°
f. The sum of the opposite angles in an isosceles trapezoid = 180°
∴ 65° + Opposite angle = 180°
Opposite angle = 180° - 65° = 115°.
The radius of the cone is 7 in and y = 25 in. What is the volume of the cone in terms of r?
х
O 392nt in
O 408rt in
0 112r in
O 117rt in
Answer:
Hi there!
The correct answer is: 408r in
Step-by-step explanation:
The formula for the volume of the cone is: V = [tex]\frac{1}{3}[/tex]π[tex]r^{2} h[/tex]
where h stands for height, in this case it's y=25
r stands for radius, in this case it's 7 in
when it says leave in terms of "r" it simply means don't multiply the π in
Answer:
392nt in
Step-by-step explanation:
Write the standard equation of a circle with center (-9,-4) and radius 15.
(x + 9)2 + (y + 4)2 = 5
(x + 4)2 + (y + 9)2 = 5
(x - 4)2 + (y- 9)2 = 5
(x - 9)2 + (y - 4)2 = 5
Answer:
Equation of a circle:
radius = the sq. rt of (x - h)^2 + (y - k)^2
Plug in the values for the center of a circle and the radius:
15 = the sq. rt of (x + 9)^2 + (y + 4)^2
(x + 9)^2 + (y + 4)^2 = 225
The answer is A or the first one.

Step-by-step explanation:
Area of trapezoid: a+b/ 2 * H
a = top, b= bottom, H = height
6+14/2 * 8
20/2 *8
10*8

Answer:
20
Step-by-step explanation:
To find area using coordinates, you would take the y-value of the first coordinate and the x-value of the second coordinate and multiply them. Then, take the x-value of the first coordinate and multiply it with the second y-coordinate. Take the second number and subtract it from the first number. for multiple coordinates, you would multiply the first and the second, the second and the third, and so on. Once you reach the last coordinate, just multiply it by the first again. then, take all of the numbers, from multiplying your coordinates and add them together and divide them by 2 to find your area.
We would start with coordinate (8,1) here because it's letter variable is W, which is first of the others alphabetically.
(8,1) (1,1)
1 x 1 = 1
8 x 1 = 8
1 - 8 = -7
next coordinate:
(1,1) (2,5)
1 x 2 = 2
1 x 5 = 5
2 - 5 = -3
next:
(2,5) (5,5)
5 x 5 = 25
2 x 5 = 10
25 - 10 = 15
next:
(5,5) (8,1)
5 x 5 = 40
5 x 1 = 5
40 - 5 = 35
-7 - 3 + 15 + 35 = 40
40/2 = 20

HELP PLEASE !!!!!!!!!!!!!!!!!!!!!!!!The coordinate of point A is -7 and the coordinate of point D is -2.
Find the distance between the points A and D.
Answer:
So we can first use the distance formula which is for 2 dimensional but seen as we're in 1 dimensions we dont have to use it. So we can just get the distance between them using a formula I made -
|a-d| = distance
So if we use that formula we can get that -7-(-2) = -7+2 = -5. Then take the absolute value which is 5.
Therefore the answer is

A line has an c intercept of 3 and a y intercept of negative 6. What is the slope intercept form of it’s equation
y=2x+3
y=2x-6
y=-2x+3
y=-2x-6
Answer:
y = 2x - 6
Step-by-step explanation:
Slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.
The y-intercept is already given and is -6.
By c intercept, I am assuming you meant x-intercept. With an x-intercept of 3, the point is (3,0). With a y-intercept of -6, the point is (0,-6).
Use the two points to find the slope using the following equation.
[tex]m=\frac{y_{2}-y_{1} }{x_{2}- x_{1} }[/tex]
Plug the points into their respective positions and solve.
[tex]m=\frac{-6-0}{0-3}\\ m=\frac{-6}{-3} \\m=2[/tex]
The slope is 2.
Your equation is y = 2x - 6.
A glass vase factory recently produced 3 vases that were chipped and 12 vases that were not. What is the experimental probability that the next vase will be chipped?
Write your answer as a fraction or whole number.
Answer:
3/15 or 1/5 or 20%
Step-by-step explanation:
3+12=15 which is the total number of vases. 3 out of 15 vases were chipped so the probability that the next vase will be chipped is 3/15 or 1/5 or 20%.

find the value of p in the equation 2p-1 over 5= p-1 over 3
Answer:
p = -2
Step-by-step explanation:
(2p -1)/5 = (p-1)/3
Using cross products
(2p-1) *3 = (p-1)*5
Distribute
6p-3 = 5p -5
Subtract 5p from each side
6p-5p -3 = 5p-5p -5
p -3 = -5
Add 3 to each side
p-3+3 = -5+3
p =-2
