19. The heights, in inches, of players on a basketball team are:
Rom4ik [11]

Hello!

Let's find the mean of each team. Let's add up all of the heights and divide by number of players.

57+63+68+72+50+63+65+69+73+71+60=711

711/11≈64.64

Now we do the same with the soccer team.

49+53+52+52+57+61+55+61+59+61+50+50+51+62+50+57=880

880/16=55

Now we subtract.

64.64-55≈10

Therefore, our answer is D) 10 inches

I hope this helps!

Ninety-three passengers rode in a train from City A to City B. Tickets for regular coach seats cost $115. Tickets for sleeper ca
masya89 [10]
To solve this, we must set up a Systems of Equations problem 
Let's say C stands for Coach seats bought and S stands for sleeper cars bought
Here are our equations we have enough information to make. 
c + s = 93 
115c + 290s = $20,320 
Lets solve for Coach seats first 
To do that we need a value for s 
In the first equation, s = 93 - c
Lets plug that in for S in the second equation 
115c + 290(93 - c) = $20,320 
Distribute and simplify 
115c + 26,970 - 290c = $20,320 
Combine like terms 
-175c + 26,970 = $20,320 
-175c = -6650
divide 
c = \frac{-6650}{-175}
c = 38
We just found out 38 coach seats were bought. 
Plug in 38 for C in this equation ⇒ 115c + 290s = $20,320 to find S
115(38) + 290s = $20,320 
Distribute and Simplify 
4,370 + 290s = $20,320 
290s = $15,950 
Divide 
S = \frac{15950}{290}
S = 55
We just completed the problem!
38 Coach seats were bought and 
55 Sleeper car seats were bought.

In the figure below which term best describes point X?
Dmitrij [34]

The answer is B. centroid, which is the intersection of three medians of the triangle's sides.

Let's look into other answers as well:

A. Circumcenter

It is the point where three perpendicular bisector meet, and is not correct as we can see there is no indication of right angles.

The first photo is what a circumcenter looks like:

C. Incenter

It is the point where the angle bisectors of the triangles meet, which is not indicated in the photo as well.

The second photo is what a incenter looks like:

D. Orthocenter

It is a point where the altitudes of a triangle intersect, and is not indicated by the figure.

The second photo is what a Orthocenter looks like:

Therefore the answer is B. Centroid.

Hope it helps!

Two numbers such that the greater number is 75 percent more than the lesser number
victus00 [196]
<h2>Greetings!</h2>

If x = the first number (equal to 1x) then the second number is 75% more than this.

This means the value of the bigger number is 100 + 75 (because 100 is the starting number and 75 is the percent bigger)

This can be shown with the following equation:

Amount * \frac{percentage}{100}

x *  \frac{175}{100} = 1.75x

1.75x is the value of the bigger number.
