he data to the right represent the top speed (in kilometers per hour) of all the players (except goaltenders) in a certain so

ccer league. Construct (a) a relative frequency distribution (b) a frequency histogram, and (c) a relative frequency histogram. What percentage of players had a top speed between 14 and 17.9 km/h? What percentage of players had a top speed less than 13.9 km/h?

Answer:

a)

0.3212

b)

The percentage of player that had a top speed less than 13.9 km/h = 0.007259 x 100 = 0.7259%

Step-by-step explanation:

a) Construct relative frequency distribution?

Speed (km/hour) Number of players Relative frequency

10 – 13.9

14-17.9

18 – 21.9

22 – 25.9

26 – 29.9

30 – 33.9

177 4/551=0.007259

8/551=0.01451

18/551=0.03266

76/ 551=0.1379

268/551 = 0.486

177/551=0.3212

(b) frequency histogram:

The percentage of player had top speed between 14 and 17.9 km/h was = 0.01451 x100 = 1.451%

The percentage of player that had a top speed less than 13.9 km/h = 0.007259 x 100 = 0.7259%

△FSB∼△ZDR .

Leya [2.2K]

Answer: 22 units.

Step-by-step explanation:

Here FSB and ZDR are two triangles.

In which, FS = 38 unit, FB = 55 unit, ZD = 15.2 unit and ZR = x unit.

Also, $\triangle FSB\sim \triangle ZDR$

Thus, By the property of similarity,

$\frac{FS}{ZD} = \frac{FB}{ZR}$

⇒ $\frac{38}{15.2} = \frac{55}{x}$

⇒ $x = \frac{55\times 15.2}{38}$

⇒ $x = \frac{836}{38}$

⇒ $x = 22$

Thus, ZR = 22 unit.

Anthony has $11,600 in his account and earns $700 per month. He spends $8,000 on a car and has other expenses totaling $900 per

ExtremeBDS [4]

Answer:

216 Months

Step-by-step explanation:

First find how much money he looses per month: 0+700-8000= -7300 on the first month. So 11600-7300=4300.

Then, he starts loosing $200 dollars per month because 900-700=200.

So 4300/20=215. So 215+1=216 months before Anthony runs out of money.

Distributive property combined like term.... 3(x+2)+14-7x

GaryK [48]

First you would distribute the 3. So it would be (3x+6)+14+7x. Since you can’t do anything inside the parentheses, you drop them. Then you’d combine like terms. 3x+7x is 10x, and 14+6 is 20. That would get you your answer, 10x+20
