Find the (a) mean, (b) median, (c) mode, and (d) midrange for the data and then (e) answer the given question. Listed below

boyakko [2]

Answer: a. 242.5 pounds

b. 236 pounds

c . 208 and 278 pounds

The results are unlikely to be representative of all players in that sport's league because players randomly selected from championship sports team not the whole league.

Step-by-step explanation:

Given : Listed below are the weights in pounds of 11 players randomly selected from the roster of a championship sports team.

278 303 186 292 276 205 208 236 278 198 208

Mean = $\dfrac{\text{Sum of weights of all players}}{\text{Number of players}}$

$=\dfrac{278+303+186+292+276+205+208+236+278+198+208}{11}\\\\=\dfrac{2668}{11}\approx242.5\text{ pounds}$

For median , first arrange weights in order

186, 198 , 205 , 208, 208 , 236 , 276 , 278 ,278, 292 , 303

Since , number of data values is 11 (odd)

So Median = Middlemost value = 236 pounds

Mode = Most repeated value= 208 and 278

The results are unlikely to be representative of all players in that sport's league because players randomly selected from championship sports team not the whole league.

Which quadratic function has a vertex point of (3,5) and passes through the<br> point (-2,55)?

Alex17521 [72]

9514 1404 393

Answer:

f(x) = 2(x -3)² +5

Step-by-step explanation:

For vertex (h, k) and scale factor 'a', the vertex form is ...

f(x) = a(x -h)² +k

We can fill in the values of h and k from your vertex, and use the values of the extra point to find 'a'.

55 = a(-2 -3)² +5

50 = 25a . . . . . . . . subtract 5

a = 2 . . . . . . . . . . . divide by 25

So, the function is ...

f(x) = 2(x -3)² +5

In standard form, that will be ...

f(x) = 2x² -12x +23

Which of the aaa-values satisfy the following inequality?

mina [271]

Answer:

a = 3

Step-by-step explanation:

When you add the given value for a with 7, the resulting answer must be less than 11.

In this case, if: a = 3

Plug in 3 for a in the equation:

7 + a < 11

7 + 3 < 11

10 < 11 (True).

A) a = 3 is your answer.
