As we are dealing only with the tubas which are part of the brass section we can ignore the percussion and woodwind for this question.

2/5 of 240 = 2/5 x 240 = 96 brass instruments

2/5 of 96 = 2/5 x 96 = 38.4 tuba players

I suspect that the question may be wrong!

A container contains water at temperature 80 degree celcius. After every 10 minutes, the change in temperature is - 4 degree cel
lilavasa [31]
For this case, the first thing we must do is define variables.
 We have then:
 x: number of minutes
 y: final temperature
 We write then the equation that models the problem:
 y = (-4/10) x + 80&#10;
 For y = 20 we have:
 20 = (-4/10) x + 80&#10;
 Clearing x:
 (4/10) x = 80 - 20&#10;&#10;x = (10/4) * 60&#10;&#10;x = 150
 Answer:
 
The temperature of the water will be 20 degree celcius after 150 minutes

In a shipment of 71 vials, only 13 do not have hairline cracks. If you randomly select 2 vials from the shipment, what is the pr
yanalaym [24]

Answer:

0.0313

Step-by-step explanation:

Given that in the shipment of 71 vials, only 13 do not have hairline cracks

Probability of not having a hairline cracks = \frac{13}{71}

If you randomly select 2 vials from the shipment

(Probability of not having a hairline cracks)' = \frac{13-1}{71-1} = \frac{12}{70}

what is the probability that none of the 2 vials have hairline cracks.

i.e (\frac{13}{71}) * (\frac{12}{70})

= 0.183 × 0.171

= 0.0313

Hence, the probability that none of the 2 vials have hairline cracks = 0.0313
