The required mean absolute deviation of the number of goals is 0.8.
What is mean?The mean of the values is the ratio of the total sum of values to the number of values.
The mean absolute deviation of the number of goals is a measure of how far the individual scores deviate from the mean (average) score.
To find the mean (average) score:
Mean = (2 + 3 + 5 + 3 + 2) ÷ 5 = 15 ÷ 5 = 3
Next, we find the absolute deviation for each score:
Absolute deviation for score 2: |2 - 3| = 1
Absolute deviation for score 3: |3 - 3| = 0
Absolute deviation for score 5: |5 - 3| = 2
Absolute deviation for score 3: |3 - 3| = 0
Absolute deviation for score 2: |2 - 3| = 1
Mean absolute deviation is given as,
= (1 + 0 + 2 + 0 + 1) ÷ 5 = 4 ÷ 5 = 0.8
So, the mean absolute deviation of the number of goals is 0.8.

Use VSEPR to predict the electron-pair geometry of N2.
A)
linear
B)
trigonal planar
C)
tetrahedral
D)
trigonal bipyramidal
Answer:
tetrahedral
Step-by-step explanation:
According to the valence shell electron pair repulsion theory (VSEPR) the shape of a molecule is dependent on the number of electron pairs on the valence shell of the central atom in the molecule.
The predicted electron pair geometry may sometimes differ from the molecular geometry due to the presence of lone pairs and multiple bonds.
If we consider each nitrogen atom in N2 independently, we will notice that each nitrogen atom has four regions of electron density. Hence the electron pair geometry is tetrahedral.

What is the y-intercept of y = sinx?
Answer:
The y-intercept is 0
Step-by-step explanation:
Here, we want to get the y-intercept value of y = sin x
From the plot of the graph, we can see that the graph of sin x touches the y-axis at the point y = 0
So therefore, the y-intercept of y = sin x is 0

Jeremiah plans on building a 5 meter long garden walkway that is paved with square stones that measure LaTeX: \frac{5}{6}5 6 meter on each side. There will be no spaces between the stones. How many stones will be needed to complete the garden walkway?
Answer:
Example 1
A backyard farmer wants to enclose a rectangular space for a new garden. She has purchased 80 feet of wire fencing to enclose 3 sides, and will put the 4th side against the backyard fence. Find a formula for the area enclosed by the fence if the sides of fencing perpendicular to the existing fence have length
L.
In a scenario like this involving geometry, it is often helpful to draw a picture. It might also be helpful to introduce a temporary variable,
W, to represent the side of fencing parallel to the 4th side or backyard fence.
Since we know we only have 80 feet of fence available, we know that
L + W + L = 80, or more simply, 2L + W = 80. This allows us to represent the width, W, in terms of L: W = 80 – 2L
Now we are ready to write an equation for the area the fence encloses. We know the area of a rectangle is length multiplied by width, so
A = LW = L(80 – 2L)
A(L) = 80L – 2L2
This formula represents the area of the fence in terms of the variable length
L.
Example 2
Returning to our backyard farmer from the beginning of the section, what dimensions should she make her garden to maximize the enclosed area?
Earlier we determined the area she could enclose with 80 feet of fencing on three sides was given by the equation
A(L) = 80L – 2L2. Notice that quadratic has been vertically reflected, since the coefficient on the squared term is negative, so the graph will open downwards, and the vertex will be a maximum value for the area.
In finding the vertex, we take care since the equation is not written in standard polynomial form with decreasing powers. But we know that
a is the coefficient on the squared term, so a = -2, b = 80, and c = 0.
Finding the vertex:

)
−

(

)
2
=
800
The maximum value of the function is an area of 800 square feet, which occurs when
L = 20 feet. When the shorter sides are 20 feet, that leaves 40 feet of fencing for the longer side. To maximize the area, she should enclose the garden so the two shorter sides have length 20 feet, and the longer side parallel to the existing fence has length 40 feet.
Example 3
A ball is thrown upwards from the top of a 40 foot high building at a speed of 80 feet per second. The ball’s height above ground can be modeled by the equation
H(t) = –16t2 + 80t + 40.
What is the maximum height of the ball?
When does the ball hit the ground?
To find the maximum height of the ball, we would need to know the vertex of the quadratic.

The ball reaches a maximum height of 140 feet after 2.5 seconds.
To find when the ball hits the ground, we need to determine when the height is zero—when
H(t) = 0. While we could do this using the transformation form of the quadratic, we can also use the quadratic formula:
t

Find the with of a triangle as a 15 cm high in a hypogynous of a 19 cm
Answer:
This other side of the triangle is equal to about 11.7 cm
Step-by-step explanation:
In order to find out the third side of the triangle we will just use the Pythagoras Theorem.
[tex]c^{2} =a^{2} + b^{2}[/tex]
Since we know the hypotenuse and we know one of the legs, in order to find the second leg we just substitute the values and solve the equation and so we get...
[tex]c^{2} =a^{2} + b^{2}\\19^{2} = 15^{2} + b^{2}\\361 = 225 + b^{2} \\[/tex]
[tex]b^{2} = 361 - 225\\b^{2} = 136\\b = \sqrt{136} \\[/tex]
And so b ≈ 11.66190

A bag with 6 marbles has 2 blue marbles, 1 red marble, and 3 yellow marbles. A marble is chosen from the bag at random. What is the probability that it is blue?
Write your answer as a fraction in simplest form.
Answer:
1/2
Step-by-step explanation:
We know the total amount of marbles in the bag, 6. Now, we need to make a fraction, there are 3 blue marbles, so our fraction is 3/6. This can be simplified to 1/2.
The required probability of the blue marble in the bag is 1 / 3.
Given that,
A bag with 6 marbles has 2 blue marbles, 1 red marble, and 3 yellow marbles. A marble is chosen from the bag at random, what is the probability that it is blue is to be determined.
What is probability?
Probability can be defined as the ratio of favorable outcomes to the total number of events.
here,
Total number of marble in the bag = 6
Total number of blue marble in the bag = 2
Probability of the blue marble in the bag = 2 / 6 = 1 / 3
Thus, the required probability of the blue marble in the bag is 1 / 3.

Answer and Step-by-step explanation:
Trigonometric Function (These only work for right triangles):
SOH-CAH-TOA
S = Sine = sin
C = Cosine = cos
T = Tangent = tan
O = Opposite (side)
H = Hypotenuse (side)
A = Adjacent (side)
SOH = sin(angle) = [tex]\frac{opposite}{hypotenuse}[/tex]
CAH = cos(angle) = [tex]\frac{adjacent}{hypotenuse}[/tex]
TOA = tan(angle) = [tex]\frac{opposite}{adjacent}[/tex]
1. sinQ (Q is the angle) = [tex]\frac{14}{50} = \frac{7}{25} = 0.28[/tex]
Use Pythagorean Theorem to find side PQ. [tex]14^{2} + PQ^{2}= 50^{2} \\PQ^{2} = 2304\\PQ = 48[/tex]
2. cosQ = [tex]\frac{48}{50} = \frac{24}{25} = 0.96[/tex]
3. tanQ = [tex]\frac{14}{48} = \frac{7}{24} = 0.29[/tex]

The gardener charged $0.50 per plant and $75 to plant all them
Answer: The question is The Gardener charged $0.50 per plant and a flat payment of $75. Which function represents this scenario?
The answer is 0.50x-75
The total cost will be the product of the gardener charged and the number of plants. The total cost is $ 37.5
What is multiplication?It is also known as the product. If the object n is given to m times then we just simply multiply them.
The gardener charged $ 0.50 per plant and $75 to plant all of them.
Let X be the gardener charged and Y be the number of plants.
The total cost will be the product of the gardener charged and the number of plants. That can be written as
Total cost = X × Y
Total cost = 0.50 × 75
Total cost = $ 37.5
