admissions to a carnival is $5 and each game at the carnival costs 0.85 you have $15 to spend on admissions and games what is th
prisoha [69]
You have $15 and admission is $5, so you know have $10 before doing any games. If you wanted to play 12 games, you would need $10.20, which you do not have. But, if you wanted to play 11 games, then you would need $9.35, which is just under $10.

So the maximum amount of games that you could play would be 11 games.

A club volleyball league allows only the top 5% of athletes who try out to be part of the team. If the team tryout scorecard has
lapo4ka [179]

Answer:

Among the given options, the one which can be used as a minimum qualifying score to join the volleyball league is, 274.

Step-by-step explanation:

Let the team tryout scorecard is represented by the random variable X.

Now, according to the question,

X \sim Normal (250 , 15)

Let Z = \frac {(X - 250)}{15}  -----------------------(1)

So, Z \sim Normal (0, 1)

According to the question, the bottom 95% in  the tryout scorecard are to be eliminated.

Let,  P(Z ≤ z_{0.95}) = 0.95

Now, from the inverse standard normal probability table,

z_{0.95} = 1.645

So, if we say that

P(X ≤ x_{0.95}) = 0.95, then

x_{0.95} = z_{0.95} \times 15 + 250 --------------[from (1)]

                    = 1.645 \times 15 + 250

                    = 274. 675

Hence, from the given options, the answer is, 274.

In ΔUVW, the measure of ∠W=90°, the measure of ∠V=72°, and VW = 6.1 feet. Find the length of UV to the nearest foot.
Dmitriy789 [7]

The length of UV is 19.7 ft.

<u>Solution:</u>

The given \triangle UVW is a right triangle because W is 90 degrees. VW is adjacent to V and UV is the hypotenuse. Adjacent any hypotenuse use the cosine function. 

Refer the image attached below for the image of the triangle.

cos\theta=\frac{adj}{hyp}

plug in known values

cos(72\°)=\frac{6.1}{x}\rightarrow(1)

The value of cos(72°) is 0.309

On substituting the above value in (1) we get,

\Rightarrow0.309=\frac{6.1}{x}\rightarrow x=\frac{6.1}{0.309}\rightarrow x=19.7411003236\approx x=19.7

Therefore, the required measure is 19.7 ft.
