If y varies inversely as x and } = 3 when x = 4, then y
Andrews [41]

Answer:

FALSE

Step-by-step explanation:

If y varies inversely as x., this is expressed as;

y = k/x

k is the proportionality constant

when y = 3 and x = 4

3 = k/4

k = 3 * 4

k = 12

when x = 15;

y = k/x

y =12/15

y = 4/5

Hence y is not equal to 12 when x = 15.

The correct answer is FALSE

The federal government requires a car manufacturer to have a minimum miles per gallon (mpg) average over the models it makes. Su
valentinak56 [21]

Answer:

25 mpg

Step-by-step explanation:

We have a set of values 19, 21, 22, 28  and 18  

The average (which is the mean of the set of values )  is :

19 + 21 + 22 + 28 + 18 = 21.6 mpg   out of the government requirement

So we need a value such as the mean become at least 25 mpg

We have to solve the equation:

(19+21+22+28+ x)/ 5  = 25

 (90 + x ) /5  = 25       ⇒   90 + x = 125   ⇒   x = 35 mpg

If we get the mean of the set of values including 35 we have:

(19 +21+ 22+ 28 + 35 ) / 5   =  25 mpg  government requirement
