Asap the weights of the watermelons in a local grocery store is normally distributed. the mean weight is 18 pounds with a standard deviation of 1.5 pounds. how much do the middle 95% of the watermelons weigh? between 15 and 21 pounds between 16.5 and 19.5 pounds between 13.5 and 22.5 pounds between 17.1 and 18.9 pounds

Since it's normally distributed, we can apply the emperical rule. The middle 95% will be within two standard deviations of the mean, so that means:

18-2(1.5), 18+2(1.5)=15,21

So we want the first option.

is only a line? i think so

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
