She must have a score greater than 69 in her final tests

Let the required score be "x"

The mean of the data is the ratio of the sum to the total sample

Mean = 80+76+85+85+x/5

80+76+85+85+2x/5 > 79

326+x/5 > 79

326 + x > 395

x > 395 - 326

x > 69

This shows that she must have a score greater than 69 in her final tests

katrin2010 [14]

Answer:

$y=\frac{24}{x}$

Step-by-step explanation:

We have been given that a certain function is an inverse proportion. We are asked to find the formula for the function if it is known that the function is equal to 12 when the independent variable is equal to 2.

We know that two inversely proportional quantities are in form $y=\frac{k}{x}$ , where y is inversely proportional to x and k is constant of variation.
