Now, We can simplify as,
The double dot plot shows the runs scored per game by two baseball teams during a 10 game seasons.
Now, We can find the value of mean as,
For team A,
Mean = (2 x 1 + 3 x 1 + 4 x 4 + 5x 2 + 6 x 1 + 7 x 1) / 10
Mean = (2 + 3 + 16 + 10 + 6 + 7) / 10
Mean = 44 / 10
Mean = 4.4
For team B;
Mean = (2 x 1 + 5 x 2 + 6 x 4 + 7 x 2 + 9 x 1) / 10
Mean = 59/10
Mean = 5.9
MAD for both team are,
For team A;
MAD = |4.4 - 2| + |4.4 - 3| + 4 |4.4 - 4| + 2 |4.4 - 5| + |4.4 - 6| + |4.4 - 7| / 10
MAD = 2.4 + 1.4 + 1.6 + 1.2 + 1.6 + 2.6 / 10
MAD = 1.08
For team B;
MAD = |5.9 - 2| + 2|5.9 - 5| + 4 |5.9 - 6| + 2 |5.9 - 7| + |5.9 - 9| / 10
MAD = 3.9 + 1.8 + 0.4 + 2.2 + 3.1 / 10
MAD = 1.14
Hence,
Mean of team A < Mean of team B
MAD of team A < MAD of team B

Hope this helped!
Answer:125 yen
Step-by-step explanation:
Ratio and proportion
Ratio=1:80=x:10,000
x represents dollars which is unknown
1/80=x/10,000
Then you cross multiply
80x=10,000
80x/80=10,000/80
x=125
Therefore,$125 will give you 10,000yen

This theorem states that [tex]a^2+b^2=c^2[/tex], where c is the hypotenuse of a triangle and a and b are the legs (the other two sides).
SolutionAs we can see from the image, we are given the lengths of the hypotenuse and one of the legs. Now, we must find x, the length of the other leg.
[tex]a^2+b^2=c^2[/tex]
Plug in the given lengths:
[tex]5^2+b^2=13^2[/tex]
Solve for b:
[tex]b=-12,12[/tex]
Since length cannot be negative, we know that b must be equal to 12.

Answer:
y = -2x
Step-by-step explanation:
the line passes through the origin (where both x and y are 0...they both meet).
that rules out it being the X +4 and x - 4 options.
the line goes from top left to bottom right, indicating that the gradient is negative. the gradient value if the number of front of the x in the equation.
negative gradient is a minus sign.
so our answer is y = -2x
this is because if you use the rise over run method, you have to go down two and over one, leaving you with -2/1 which is simplified to -2
Victor left his house at a speed of 18km/hr. When victor was 1/2 km away from his house, his brother Alex left the ouse riding his bike towards Victor at a rate of 24km/hr. How long will it take Alex to catch up to Victor
Answers
Answer: it will take Alex approximately 42.86 seconds to catch up to Victor.
Step-1:- To determine the time it will take for Alex to catch up to Victor, we can use the concept of relative speed.
The relative speed = Seed of victor+ Speed of Alex brother
relative speed= 18 km/hr + 24 km/hr = 42 km/hr.
Step-2 :- Since Alex is starting from 1/2 km away from the house, the distance he needs to cover to catch up to Victor is also 1/2 km.
Using the formula: time = distance / speed
therefore time = [tex]\frac{1/2}{42}[/tex] we can calculate the time it will take for Alex to catch up to Victor:
time = [tex]\frac{1}{2} \frac{1}{42}[/tex]/hr = 0.0119 hours or
Now Converting hours into seconds
1 hr = 3600 seconds
0.0119 hr = 0.0119×3600 seconds
Time = 42.86 seconds.
A quadratic function is defined by f(x) = x^2 - 8x - 4 Which expression also defines f and best reveals the maximum or minimum of the function?
Answers
Answer: D
Step-by-step explanation:
(x-4)²-20
(x-4)(x-4)-20
(x^2)-8x+16-20
= (x^2)-8x-4
D is the same equation as in the question, just written in another form (they are equal). In this form (vertex), the vertex is (h,k), which is easily found in this equation. The vertex reveals the maximum or minimum. The vertex in this problem is (4,-20) because vertex form is f(x)=a(x-h)^2 + k.

Area of five squares = 1289.09 square units
Perimeter = 194.6 units
Step-by-step explanation:
Area of square and perimeter:
First find the length of each square, then find the area of each square.
To find the area of five squares, add all the area of each square.
Side of square1 = 27 units
[tex]\sf Side \ of \ square2 = \dfrac{2}{3}*27=2*9 = 18 \ units\\\\Side \ of\ square3= \dfrac{2}{3}*18=2*6=12 \ units\\\\Side \ of \ square4=\dfrac{2}{3}*12=2*4=8 \ units\\\\Side \ of \ square5=\dfrac{2}{3}*8=\dfrac{16}{3}=5.3 \ units[/tex]
Area of square1 = 27*27 = 729 square units
Area of square2 = 18*18 = 324 square units
Area of square3 = 12*12 = 144 square units
Area of square4 = 8*8 = 64 square units
Area of square5 = 5.3*5.3 = 28.09 square units
Area of five squares = 729 + 324 + 144 + 64 +28.09
= 1289.09 square units
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Perimeter of the composite figure = (27 + 27+27+9) + (18+18+6) +(12+12+4) + (8+8+2.7)+ (5.3+5.3+5.3)
= 90 + 42 + 28 + 18.7 + 15.9
= 194.6 units
the perimeter is 194.6 units

Answer: The area of the given shape is 9.734 meter square
Step-by-step explanation:
The given shape is a square with 4 sides of equal dimensions "a",
Area of Square = Square of its side "a"
Here, a = Hypotenuse of the inner triangle
Step 1: Get the hypotenuse value of the inner right triangle as the base and height dimensions of the right triangle is given.
Step 2: By using Pythagoras theorem,
Square of the base + Square of the height = square of the Hypotenuse
(2.4)^2 + (2.0)^2 = 9.76
Therefore the value of the hypotenuse = 3.12m
The area of the square = 9.734 meter square.
