The lifespans of zebras in a particular zoo or normally distributed the average zebra lives 20.5 years the standard deviation is 3.9 years use the empirical rule to estimate the proper Millatti of a zebra living between 16.6 and 24.4 years

68% of the zebras have lifespan between 16.6 and 24.4 years.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 20.5 years

Standard Deviation, σ =  3.9 years

Empirical Formula:

We have to find the percentage of Zebras having lifespan between 16.6 and 24.4 years.

We can write:

Thus, by empirical rule around 68% of data lies within one standard deviation from the mean.

Thus, 68% of the zebras have lifespan between 16.6 and 24.4 years.

false.

step-by-step explanation:

false.

cavalieri's principle makes that statement about the volumes, not about the areas.

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3
