Answer:

  • Mean = 261.63 pounds
  • Median = 278 pounds
  • Modes: 278 & 281
  • Mid-range = 242
  • Yes all the results will be able to represent all players in the sports league

Step-by-step explanation:

First of all, we will sort the data.

185 227 234 245 278 278 279 281 281 291 299

<u>Mean:</u>

Mean is defined as the sum of values divided by the number of values.

n = 11

Mean = \frac{sum}{n}\\= \frac{185+227 +234+ 245+ 278+ 278+ 279+ 281+ 281+ 291+ 299}{11}\\=\frac{2878}{11}\\=261.63\ pounds

<u>Median:</u>

As the number of values is odd,

The median will be:

Median = (\frac{n+1}{2})th\ value\\= \frac{11+1}{2}\\=\frac{12}{2}\\=6th\ value

The 6th value is 278

Median = 278

<u>Mode:</u>

Mode is the most frequent value in a data set.

In the given dataset,

278 and 281 are modes as both are repeated twice

<u>Mid-range:</u>

Mid-range is the average of maximum and minimum value

So,

Min = 185

Max = 299

So,

Mid-range = \frac{Max+Min}{2}\\= \frac{185+299}{2}\\= \frac{484}{2}\\= 242

Hence,

  • Mean = 261.63 pounds
  • Median = 278 pounds
  • Modes: 278 & 281
  • Mid-range = 242
  • Yes all the results will be able to represent all players in the sports league

(3x3 - 2x2 - 7x + 6) = (x + 1) synthetic division ​
ValentinkaMS [17]

Answer:3/2

3x3-2x2-7x+6=x+1(Multiply the numbers)

9-4-7x+6=x-1(Calculate)

11-7x=x-1(Move the terms)

-7x-x=-1-11(Collect like terms&calculate)

-8x=-12(Divide both sides by -8)

x=3/2

Circle G and X connect at point Y. The length of G Y is 10 centimeters and the length of Y X is 16 centimeters.
In-s [12.5K]

Answer:

676π Sq. cm.

Step-by-step explanation:

The line GY is the radius of the circle with G as center and Y is a point on the circle.

Now, GY = 10 cm.

Again, the line XY is the radius of the circle with X as center and Y is a point on the circle.

Now, XY = 16 cm

The two circles touched at point Y,

Therefore, point Y will be on line GX.

Now, GX = GY + YX = 10 + 16 = 26 cm.

Therefore, Marco wants to create a new circle using GX as the radius, then the area of the new circle will be π (26)² Sq. cm. = 676π Sq. cm. (Answer)
