Randy can buy 6 gallons of gas for $18 or 7 gallons of gas for $21. How much do you think he would pay for 8 gallons of gas? A)

ryzh [129]

Well, we want to find how much it would cost for 1 gallon, the easiest way to do that is subtract 21 from 18.

21 - 18 = 3

So, it's 3 dollars per gallon. Now that we know that we multiply it by 8 to find how much it would cost.

8 x 3 = 24

Eight gallons of gas would cost 24$ :D

In a group of 20 pupils, 3 play the flute only.

spin [16.1K]

Answer:

$\dfrac{1}{4}$

Step-by-step explanation:

Given information:

Total number of pupils = 20
3 pupils play the flute
6 pupils play the piano only
6 play both instruments

We can assume that 3 pupils play the flute <u>only</u> as we have also been told that 6 pupils play both instruments.

To calculate the probability that a randomly chosen pupil plays neither instrument, first determine how many pupils do not play an instrument by subtracting the number of pupils who do play an instrument from the total number of pupils:

⇒ total number of pupils - pupils who play instruments

⇒ 20 - (3 + 6 + 6)

⇒ 20 - 15

⇒ 5

Therefore, 5 pupils do not play the piano and/or flute.

To calculate probability:

$\sf Probability\:of\:an\:event\:occurring = \dfrac{Number\:of\:ways\:it\:can\:occur}{Total\:number\:of\:possible\:outcomes}$
