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.

A water tank already contains 55 gallons of water when Baxter begins to fill it. There is a crack in the tank and water begins t

STALIN [3.7K]

Answer:

Step-by-step explanation:

Therefore, the volume of the water in the tank 25 minutes after Baxter begins filling the tank is 255 gallons.

Step-by-step explanation:

Linear Equation; Ax+By=C

A linear equation to model this situation:

8x + 55 = C

Where;

8 is for the rate of gallons.

'X' is the minutes.

55 is the gallons of water the tank already contained.

8(25) + 55 = 255

Where;

8 is for the rate of gallons.

25 is the minutes.

55 is the gallons of water the tank already contained.

If f(x) = 3 – 2x and g (x) = StartFraction 1 Over x + 5 EndFraction, what is the value of (StartFraction f Over g EndFraction) (

vredina [299]

For this case we have the following functions:

$f (x) = 3-2x\\g (x) = \frac {1} {x + 5}$

We must find: $\frac {f} {g} (8)$

By definition we have to:

$\frac {f} {g} (x) = \frac {f (x)} {g (x)}$

So:

$\frac {f (x)} {g (x)} = \frac {3-2x} {\frac {1} {x + 5}} = (3-2x) (x + 5)$

Thus, we have to:

$\frac {f} {g} (8) = (3-2 (8)) (8 + 5) = (3-16) (13) = - 13 * 13 = -169$

So, the value is -169
