Suppose the heights of the members of a population follow a normal distribution. If the mean height of the population is 65 inches and the standard deviation is 3 inches, 68% of the population will have a height within which of the following ranges?

4hours and 40 mins she would be 120 meters high

pretty sure its b

step-by-step explanation:

why? because i noticed a pattern. 60 120. those numbers without the zero, make the 6 times tables leaving your answer to be b since 6 times 4 is 24 and adding a zero making it 240.

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
