25 points for this please help with step by step
a) 20.9
The mean is calculated by adding up the scores and dividing the total by the number of scores, it is also called the average.
First, we can count and see there are 11 players (makes sense for a football team). Adding up the ages gives us 19 + 19 + 20 + 20 + 20 + 21 + 22 + 22 + 22 + 22 + 23 = 230. Divide by 11 and we get a mean of of about 20.9!
b) 30
To figure this out, we will set up an equation that looks like this:
[tex]\frac{19 + 19 + 20 + 20 + 20 + 21 + 22 + 22 + 22 + 22 + 23+x}{12} =22[/tex]
And now we will solve:
[multiply both sides by 12] 230 + x = 264
[subtract 130 from both sides] x = 30
So the age of the new player should be 30!
Have a nice day!

Answer:
The larger angle is 144 degrees and the smaller angle is 36 degrees
Step-by-step explanation:
Because this is a supplementary angle you have to find out what x is to solve this equation [tex]2.4x+9.6x=180[/tex]
Because 2.4x and 9.6x are like terms we add them [tex]2.4x+9.6x=12x[/tex]
So now to find x we divide 180 by 12 to get 15 [tex]\frac{12x}{12} =\frac{180}{12}[/tex]
We replace the x with 15 [tex]2.4(15)+9.6(15)=36+144[/tex]
We add 36 and 144 which equals 180
2x+12=18-x

By matching the statistical measures with their corresponding values, we have:
Median: 23.5
Mean: 22.5
Mode: 20, 24, 25, 26
Lower Quartile: 21.5
Upper Quartile: 24.5
To match the statistical measures with their corresponding values, we need to analyze the dataset and identify the appropriate measures. Here's the breakdown:
Median: The median is the middle value of the dataset when it is arranged in ascending order. In this case, since we have 12 data points, the middle two values are 23 and 24. Therefore, the median is the average of these two values, which is 23.5.
Mean: The mean is calculated by summing up all the values in the dataset and dividing by the total number of values. Adding up the given values, we get 262. Dividing this sum by 12 (the number of values), we obtain a mean of 22.5.
Mode: The mode represents the value(s) that appear(s) most frequently in the dataset. In this case, the values 20, 24, 25, and 26 all appear twice, making them the modes of the dataset.
Lower Quartile: The lower quartile divides the dataset into four equal parts, with 25% of the data falling below it. To find the lower quartile, we need to locate the value that is greater than or equal to 25% of the data. In this case, the 25th percentile falls between the values 21 and 22. The lower quartile is the average of these two values, which is 21.5.
Upper Quartile: The upper quartile divides the dataset into four equal parts, with 75% of the data falling below it. Similar to the lower quartile, we need to locate the value that is greater than or equal to 75% of the data. In this case, the 75th percentile falls between the values 24 and 25. The upper quartile is the average of these two values, which is 24.5.

The probable question may be:
"Match the statistical measures (median, mean, mode, lower quartile, upper quartile) with their corresponding values for the dataset: 20, 20, 21, 22, 23, 23, 24, 24, 25, 25, 26, 26."
The tiles provided represent potential statistical measures and values, and the task is to match the correct measure with its corresponding value.

A line has a slope of zero. Which of the following points could this line pass through?
(3, -6) and (7, -6)
(-8, 6) and (8, -6)
(12, 9) and (12, 6)
(3, 4) and (4, 6)
(-8, 6) and (8, -6)
(12, 9) and (12, 6)
(3, 4) and (4, 6)
Step-by-step explanation:
The answer would be (3,-6) and (7,-6) because if the slope is zero it wouldn't go any where it would stay the same, and I'm pretty sure it would be negative.

The owner of a lemonade stand mixes juice that costs 2 dollars per gallon with juice that costs 7 dollars per gallon. She gets 20 gallons of punch that costs 4 dollars per gallon. How much of each juice does she use?
Answer:
8 gallons at $7
12 gallons at $2
Step-by-step explanation:
x gallons at $7 with the remaining (20 - x) gallons at $2 to get 20 gallons at $4
x(7) + (20 - x)(2) = 20(4)
Distribute
7x + 40 - 2x = 80
Combine like terms
5x + 40 = 80
Subtract 40 from both sides
5x = 40
Divide both sides by 5
x = 8 gallons at $7
20 - x = 12 gallons at $2

I think the best deal would be 14 oz
explanation:The 10 0z, 1 oz would be equal to 25 cents and when you add 4 oz the price would have been 3.50 if it was going off of the same ratio as the 10 oz bottle. the 16 oz bottle is the same ratio as the 10 oz bottle and the 18 oz bottle would be 30 cents per oz.
