Answer:
Mean: 29.6
MAD: 10
Step-by-step explanation:
Answer:
Mean = 29.6
MAD = 10
Step-by-step explanation:
For the mean, just add all of the points together and divide it by 10 since there are 10 games.
For the MAD, use the mean and subtract is from each of the games. As an example, just do 23-29.6 and ignore if it is a negative sign. Do it for all and then add up the leftovers. Then divide it by the 10 games.
(6.6+1.4+1.6+8.4+10.6+8.4+15.4+4.6+26.6+16.4)/10

The system of equations for each point are mentioned below.
What is a mathematical function, equation and expression? function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Given is to find two systems of linear equations that have the given point as a solution.
For the point (- 2, 1), we can write the system of equations as -
1 = - 2m₁ + c₁
1 = - 2m₂ + c₂
For the point (3, - 2), we can write the system of equations as -
- 2 = 3m₁ + c₁
- 2 = 3m₂ + c₂
For the point (0.5, 1), we can write the system of equations as -
1 = (1/2)m₁ + c₁
1 = (1/2)m₂ + c₂
For the point (0, 4), we can write the system of equations as -
4 = c₁
4 = c₂
Therefore, the system of equations for each point are mentioned above.

Engineers must consider the breadths of male heads when designing motorcycle helmets. Men have head breadths that are normally distributed with a mean of 6.0 inches and a standard deviation of 1.0 inches. If one male is randomly selected, find the probability that his head breadth is less than 6.2 inches.
Answer:
0.57926
Step-by-step explanation:
Given that :
Mean, m = 6
Standard deviation, s = 1
P(x < 6.2)
Obtain the Zscore :
Zscore = (x - m) / s
Zscore = (6.2 - 6) / 1
Zscore = 0.2
P(Z < 0.2) = 0.57926 (Z probability calculator)
Probability of having head breadth less than 6.2 is 0.57926

Answer: x=73 y=73 z=107
Step-by-step explanation:
The angel of x is 73° because opposite angles are always the same.
The angle of y is also 73° because it is on a parallel line so angles on a parallel line would be the same.
Then the angle of z is 107° because the other side of z would be 73° so you need to deduct this from 180° (because a straight line always adds up to 180°).

A bowl has 56.5 cm for the circumference what is the radius?
A drum has 75.4 in for the circumference what is the radius?
Answer:
1. 17.59
2. 81.68
3. 8.99225
4. 12.00028
Step-by-step explanation:
for the first two you have to multiply the radii by 2 to find the diameter, then multiply your diameter by pi (3.14) to find the circumference
for the second two you have to work backwards so you have to divide the circumference by pi (3.14) which will give you the diameter, then you have to divide the diameter by 2 to get the radius.

find the slope of the line parallel to this equation: y=2/5x-4
Answer:
slope = [tex]\frac{2}{5}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = [tex]\frac{2}{5}[/tex] x - 4 ← is in slope- intercept form
with slope m = [tex]\frac{2}{5}[/tex]
Parallel lines have equal slopes
Thus the slope of a parallel line is m = [tex]\frac{2}{5}[/tex]
Help!?!! Im sooo confused
Which function does the graph represent?
Of(x) = (x - 2)2 + 3
Of(x) = -(x - 2)2 + 3
Of(x) = (x + 2)2 + 3
O f(x) = -(x + 2)2 + 3
Answer:
The function which represents the graph is:
[tex]y=-\left(x\:-\:2\right)^2+\:3[/tex]
Hence, option B is correct.
The graph is also attached.
Step-by-step explanation:
From the graph, it is clear that:
The vertex = (2, 3)
The y-intercept = (0, -1)
Let us check the equation
[tex]y=-\left(x\:-\:2\right)^2+\:3[/tex]
Determining the y-intercept:
The value of the y-intercept can be determined by setting x = 0, and determining the corresponding value of y.
substituting x = 0 in teh equation
[tex]y=-\left(x\:-\:2\right)^2+\:3[/tex]
[tex]y=-\left(0\:-\:2\right)^2+\:3[/tex]
[tex]y=-2^2+3[/tex]
[tex]y=-4+3[/tex]
[tex]y=-1[/tex]
Thus,
The point representing the y-intercept is: (0, -1)
Determining the vertex:
The vertex of an up-down facing parabola of the form ax² + bx + c is:
[tex]x_v=-\frac{b}{2a}[/tex]
As the equation is
[tex]y=-\left(x\:-\:2\right)^2+\:3[/tex]
Rewriting the equation [tex]y=-\left(x\:-\:2\right)^2+\:3[/tex] in the form ax² + bx + c:
[tex]y=-x^2+4x-1[/tex]
The Parabola params are:
[tex]a=-1,\:b=4,\:c=-1[/tex]
Thus,
[tex]x_v=-\frac{b}{2a}[/tex]
[tex]x_v=-\frac{4}{2\left(-1\right)}[/tex]
[tex]x_v=2[/tex]
Now plug in [tex]x_v=2[/tex] in the equation to find [tex]y_v[/tex]
[tex]y_v=-x^2+4x-1[/tex]
[tex]\:y_v=-\left(2\right)^2+4\left(2\right)-1[/tex]
[tex]y_v=-4+8-1[/tex]
[tex]y_v=3[/tex]
Therefore, the vertex of the equation is: (2, 3)
Hence, the function which represents the graph is:
[tex]y=-\left(x\:-\:2\right)^2+\:3[/tex]
Hence, option B is correct.
The graph is also attached.

Six times the lesser of the two consecutive even integers is 4 times the greater even integer. What are the integers?
Answer:
Integers are 4 and 6
Step-by-step explanation:
Let the two consecutive even integers be [tex]x,x+2[/tex] such that [tex]x<x+2[/tex]
Six times the lesser of the two consecutive even integers is 4 times the greater even integer.
So,
[tex]6x=4(x+2)\\6x=4x+8\\6x-4x=8\\2x=8\\x=4[/tex]
Other integer [tex]=x+2=4+2=6[/tex]

A 2-column table with 5 rows. Column 1 is labeled Number of friends helping with entries 0, 1, 2, 3, 4. Column 2 is labeled Hours to build tree house with entries 20, 20 minus 20 (0.10) = 18.0, 18 minus 18 (0.10) = 16.2, 16.2 minus 16.2 (0.10) = 14.6, question mark.
Peter figures he can build the entire tree house by himself in 20 hours. He figures that each additional friend who helps him would improve the time by 10%. He created a table using the algebraic expression n – n(0.10), where n is the previous number of hours.
To the nearest tenth of an hour, how long will it take to build the tree house if 4 friends are helping?

George and Lea each toss a tetrahedral die with faces numbered 1 through 4, and then multiply the two resulting numbers. If the product is less than 9, George wins; otherwise, Lea wins. What is the probability that Lea will win? Express your answer as a common fraction.
Answer:
I think the total number of combinations of 3 from 6 = 6C3 = 20
All possible combinations of 3 which have a product divisible by 3 must contain either a 3 or a 6.
So the number not divisible must be 3 combinations from the number 1, 2, 4, and 5.= which is 4
So the required probability is 20-4 ? 20 = 16/20 = 0.8 Answer
Hope this help you! :)
Question 8 of 10
Which equation represents the slope-intercept form of the line below?
y-intercept = (0,2)
slope = -3/7
Answer:
y = (-3/7)x + 2
Step-by-step explanation:
slope-intercept form is y = mx + b, where m = slope and b = y-intercept.
all you need to do is plug the values into the equation! :)
since your slope is (-3/7), plug that in for m.
y = mx + b ⇒ y = (-3/7)x + b
and since your y-intercept is 2, plug that in for b.
y = (-3/7)x + b ⇒ y = (-3/7)x + 2
therefore, the line's equation in slope-intercept form is y = (-3/7)x + 2.
don't worry about the parentheses, i only put them in there to separate the 7 in -3/7 from x. i'm not good at putting equations in here on brainly lol i just wanted to make sure you didn't think that it was -3 over 7x.
i hope this helps! have a lovely day <3
