The following table shows the scores of three Redbirds and the Rockets in the first six games of the basketball season.
Part A:
Which team had the higher average (mean) score? What was it?
Part B:
Which team had the higher median score? What was it?
Part C: Which team had the higher range? What was it?
PLEASE don’t answer if you don’t know the answer. Whoever answers correctly will get Brainliest :)
Answer:
Step-by-step explanation:
1) mean: sum the values and divide for how many they are
Red birds: (87+94+99+85+106+111)/6 = 97
Rockets : (93+107+87+89+108+92)/6 = 96
the Red birds have the higher mean, that is 97
2) median
set the numbers from the least to the greatest and check the number in the middle
Red birds: 85, 87, 94, 99, 106, 111
there are two numbers in the middle, so we have to added up them and divide the result by two
median = (94 + 99)/2 = 96,5
Rockets = 87, 89, 92, 93, 107, 108
median = (92+93)/2 = 92,5
the Red birds have the higher median, that is 96,5
3) range: difference between the highest and the lowest value
Red birds = 111 - 85 = 26
Rockets = 108 - 87 = 21
the Red birds have the highest range, that is 26

Five multiplied by a certain number is added to two
5 * x + 2
equals four times the number plus four

Subtract 4x from both sides
x + 2 = 4
Subtract 2 from both sides

Answer:
52 cm^2
Step-by-step explanation:
1) find the area of the rectangle
A = base x width = 8 x 5 = 40 cm^2
2) find the area of the triangle
A = (base x height)/2 = (8x3)/2 = 12 cm^2
3) find the total area
A = 40 + 12 = 52 cm^2
Answer:
52 cm^2Step-by-step explanation:
Area = 8 x 5 + 4 x 3 x 1/2 x 2
Area = 40 + 12 x 1/2 x 2
Area = 40 + 6 x 2
Area = 40 + 12
Area = 52

A translation 6 units to the right and 6 units up, then a 180° rotation about point B. The correct option is B.
What is translation?The process of changing the location of the image on the coordinate system will be known as the translation. Each point in a figure is moved the same distance in the same direction using a type of transformation known as translation.
It is given that triangles XYZ and ABC are congruent. The side length of each square on the grid is 1 unit.
In the figure, we can see the translation 6 units to the right and 6 units up, then a 180° rotation about point B.
Therefore, the translation is 6 units to the right and 6 units up, then a 180° rotation about point B. The correct option is B.

I feel like graph math ever clearly states what they want you to understand or give an answer to. you are just supposed to "get it" and most people don't just "get it". anyway.. so add the red lines y value at the x of 2 with the green lines y value at 2

At the store you have 2 options for Speedy Clean Laundry Detergent. One bottle costs $4.99 for 50 fl . oz The other bottle costs $7.50 for 90 fl. oz Which is the better buy?
Answer: the bigger bottle (90 fl. oz) is better value
Step-by-step explanation:
One method is to scale the quantities up to the same value.
The LCM (lowest common multiple) of 50 and 90 is 450
9 of the smaller bottle will cost $44.95 and contain 450 fl. oz
5 of the bigger bottle will cost $37.50 and also contain 450 fl. oz
A second method is to find the cost per (say) 10 fl. oz from each bottle
In the 50 fl. oz bottle each 10 fl. oz costs 4.99 / 5 = $0.998
In the 90 fl. oz bottle each 10 fl. oz costs 7.50 / 9 = $0.8333...

write two equivalent expressions one exponential and one a product of factors, for 4 to the 5th power evaluate the expressions
Answer:
4^5 = 1024
4×4×4×4×4 = 1024
Step-by-step explanation:
An exponential expression is going to have an exponent representing the repeated multiplication. 4 times itself 5 times over is 4^5.
A product of factors is going to show the multiplication written out sort of in a long format:
4 × 4 × 4 × 4 × 4
4^5 = 1024
4×4×4×4×4 = 1024

If the perimeter of the triangle is 64 units, then the length of the side PR is 24 units.
What is a Triangle?This is referred to as a three-sided polygon that consists of three edges and three vertices and the longest side is referred to as the hypotenuse.
The perimeter of a triangle is the sum of all the sides which is:
P = a + b + c
64 = 3x +4x - 1 + x + 1
64 = 8x

Find m P. Quadrilateral
Answer:
m∠P = 107º
Step-by-step explanation:
Since two sides are parallel this is a trapezoid
In a trapezoid, the angles on the same leg (called adjacent angles) are supplementary, meaning they add up to 180 degrees.
(7x + 31) + (21x - 19) = 180
combine like terms
28x + 12 = 180
Subtract 12 from both sides
28x = 168
Divide both sidees by 28
x = 6
m∠P = 21x - 19
m∠P = 21(6) - 19
m∠P = 107º

Given L || M find the value of unknown angles in each of the following figures
Answer:
Angle x = 120 degrees
Angle y = 60 degrees
Step-by-step explanation: Angle x has to be equivalent to the 120 degree angle that is already given since lines l and m are parallel as well as lines p and q. To find angle y, you must realize that angles x and y are supplementary angles, so their sum is 180 degrees. Since we now know that angle x is 120 degrees, you must subtract 120 from 180 in order to find the value of angle y: 180 - 120 = 60 degrees. I'm sure that there are other methods to figuring this question out, but this is how I did it.
Calculate the sample mean and sample variance for the following distribution of heights in centimeters for an 8 year old boy
Answer: To calculate the sample mean of a distribution, you add up all the values and divide by the number of values in the sample. The sample mean is also known as the average.
The formula for the sample mean is:
X-bar = (X1 + X2 + ... + Xn) / n
To calculate the sample variance of a distribution, you first need to calculate the sample mean. Then, for each value, you subtract the sample mean and square the result. You add up all these squared differences, and divide the sum by the number of values in the sample.
The formula for the sample variance is:
s^2 = ( (X1 - X-bar)^2 + (X2 - X-bar)^2 + ... + (Xn - X-bar)^2 ) / (n - 1)
It would be helpful to have the sample data, however I cannot complete this task without it.
Please provide me with the data.

Can some one tell me what 132 divided by 12 is I’m so embarrassed
132 divided by 12 is equal to 11 with a remainder of 2.
To perform the division, you can use long division:
Step 1: Set up the division equation:
_______
12 | 132
Step 2: Identify how many times 12 can fit into the first digit of 132 (1). Write the quotient (result) above the line:
11
_______
12 | 132
Step 3: Multiply the divisor (12) by the quotient (11) and write the result below the first part of the dividend:
11
_______
12 | 132
- 12
_______
Step 4: Subtract the result from step 3 from the first part of the dividend (132 - 12 = 120). Write the new result below the line:
11
_______
12 | 132
- 12
_______
120
Step 5: Bring down the next digit of the dividend (in this case, the digit "3") and put it next to the remainder (120):
11
_______
12 | 132
- 12
_______
120
3
Step 6: Determine how many times 12 can fit into 120. The answer is 10. Write the new quotient digit (10) above the digit "3":
11
_______
12 | 132
- 12
_______
120
3
_______
110
Step 7: Multiply the divisor (12) by the new quotient digit (10) and write the result below the second part of the dividend:
11
_______
12 | 132
- 12
_______
120
3
_______
110
- 108
_______
Step 8: Subtract the result from step 7 from the second part of the dividend (110 - 108 = 2). Write the new result below the line:
11
_______
12 | 132
- 12
_______
120
3
_______
110
- 108
_______
2
Step 9: There are no more digits to bring down from the dividend, and the remainder is less than the divisor. The division process is complete.
The final result is the quotient (11) with a remainder of 2. So, 132 divided by 12 is 11 with a remainder of 2.

Write the equation of the ellipse with a center at (5,-2), one vertex at (2, -2) and a focus at
(5+ √5,-2)
On solving the provided question we can say that - the value of the ellipse will be (5+ , root5)
what is ellipse?In mathematics, an ellipse is a planar curve that encompasses two focus points and ensures that the sum of the two distances from any point on the curve to the focal points is constant. In doing so, the circle—a particular variety of ellipse with two equal focus points—is generalized. The ellipse, whose eccentricity is less than 1, indicates the area containing the points whose distances from its two foci add up to a certain amount. Running tracks in sporting arenas and 2D egg forms are two straightforward examples of ellipses in daily life.
here we have,
center at (5,-2), one vertex at (2, -2) and a focus at
