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!

What is 5x-y=1/4 in slope intercept form? PLEASE give me step by step explanation and why you did what. Thank you! ❤
Answers
Answer:
y=5x-1/4
Step-by-step explanation:
The slope-intercept form would be y=mx+b, where y would be on one side. In this case, we would have to move y to one side. You can add y on both sides to move it on the right. Then, you would subtract 1/4 on both sides to move it to the left so that y is on its own side. Then the equation would equal y=5x-1/4, where 5 = m and -1/4 = b.
Answer:
The calculation to your equation is:

Find the volume of a scented candle that is in the shape of a cylinder with a diameter of 16 centimeters and a height of 20 centimeters. Round to the nearest tenth.
*there is no diagram*
Answers
Answer:
4021.2 cm³
Step-by-step explanation:
you start by getting the radius, the radius is half the diameter which in this case half of 16 is 8 so 8 is your radius and you already know the height which is 20, now that we have the radius and the height we can start
the formula for finding the volume of a cylinder is πr² · h
so are formula would be π8² · 20 which turns into π64 · 20 which then turns into 1280π or 4021.238...
which you then said we need to round the nearest tenth so 4021.238 to the nearest tenth is 4021.2 cm³

An online media service offers video and music downloads. Each download of a song costs $1. Each download of a video costs 5 times as much as the song download. You have a credit of $70. How many songs can you purchase after buying 12 videos?
Answers
Answer:
You can purchase 10 songs after buying 12 videos.
Step-by-step explanation:
Step 1 - Find out how much downloading a video costs. If the cost of a video download is 5 times as much as a song download costs, and a song download is $1, then you'd have to multiply 5 x $1, which equals 5. So downloading a video costs $5.
Step 2 - Find how much it costs to buy 12 videos by multiplying the cost of 1 video to how many you bought, 12. We already found out 1 video costs $5, so that would 12 x $5, which equals $60. That means those 12 video downloads costed you $60 dollars.
Step 3 - Find out how many songs you can buy with your remaining credit. If you already payed $60 dollars worth of videos, then you only have $10 dollars left to spend because $70 - $60 is $10. So if every song costs $1 dollar, then you'd be able to purchase 10 more songs until you reach your credit, $70 dollars.
