Step-by-step explanation:

Greta’s sample is Biased . The generalization made from the sample is Not Valid .

This is because Greta only asked HER classmates and not from other classes. Besides, that sample if too small for a population as big as most 7th graders. (I got this right in my test from Edmentum). Hope I Helped!!! :)

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
