I am stupid too, so forgive me if I am wrong.ಥ_ಥ

I am pretty sure the correct answer is D since 2 can be multiplied by 3 to get 6, and 3 can be multiplied by 3 to get 9. Thus, if the number of guitars is multiplied by 3, the number of amps will always be a multiple of 3.

Nicole is playing a video game where each round lasts \dfrac{7}{12} 12 7 start fraction, 7, divided by, 12, end fraction of an

Harrizon [31]

Total number of hours she schduled to play the game = 3 $\frac{3}{4}$ hours.

Let us convert mixed fraction into improper fraction

$3\frac{3}{4} = \frac{3*3+4}{4} = \frac{13}{4} \ hours.$

Duration of each round = $\frac{7}{12}$ .

In order to find the number of rounds Nicole can play, we need to divide total number of hours by duration of each round.

$\frac{13}{4}$ ÷ $\frac{7}{12}$

Converting division sign into multiplication flips the second fraction.

$=\frac{13}{4} \times \frac{12}{7}$

Crossing out 12 by 4, we get 3 on the top of second fraction.

$=\frac{13}{1} \times \frac{3}{7}$

$=\frac{39}{7} = 5.57...( Approximately).$

Because problem is about number of rounds.

So, total number of round would be 5.

The easiest way to determine the score is to use a calculator or spreadsheet and the appropriate probability function.

If you want the top 10%, the score corresponds to the 90th percentile. That score is 316.

If you want the top 15%, the score corresponds to the 85th percentile. That score is 313.

kari74 [83]

Let the angle of elevation be θ.

We have a right angled triangle with an opposite of 300.5 ft. (306 - 5.5) and an adjacent of 400 ft. Recalling SOH CAH TOA, tanθ = O/A.
tan(θ) = 300.5/400.
θ = tan^-1(300.5/400).
θ = 36.9°.
