Answer:  186

<u>Step-by-step explanation:</u>

                 <u>    Jazz           </u>            <u>Rock or Pop  </u>

7-12:          200 - 142 = 58                  142

13-18:        72 - 58 = 14                200 - 14 = 186

It is given that 142 out of 200 students in age group 7-12 like Rock or Pop.

Therefore, 200-142 = 58 in that age group like Jazz.

Total Jazz in both age groups is 72, so 72 - 58 (7-12: Jazz) = 14 students in age group 13-18 like Jazz.

There are 400 students total and 200 are in age group 7-12, which leaves 400-200 students in age group 13-18.  200 - 14 (13-18: Jazz) = 186 students in age group 13-18 like Rock or Pop.

svetoff [14.1K]

Answer:

Step-by-step explanation:

In this case the solution of the integral is

\int\limits^{2\pi} _0 {} \, d\phi \int\limits^R_0 {\rho}h \, d\rho = [2\pi - 0](\frac{1}{2} )[R^{2} - 0]h = \pi R^{2}h

because h is a constant, and where the expression

\int {\rho} \, d\rho = \frac{\rho^{2}}{2}

was used.

I hope this is usefull for you

Lemur [1.5K]

Answer:

B. 2:1, for every two yellow fish there is one orange fish

Step-by-step explanation:

So you have 6 yellow fish and 3 orange fish.

You can divide both these values by 3 to get:

2 yellow fish: 1 orange fish

Therefore, the simplified version of the ratio is 2:1

In context this means for every 2 yellow fish there is 1 orange fish.

The answer is then B.
