The lifespans of zebras in a particular zoo are normally distributed. The average zebra lives 20.520.520.5 years; the standard deviation is 3.93.93.9 years. Use the empirical rule (68-95-99.7\%)(68−95−99.7%)(68-95-9 9.7%) to estimate the probability of a zebra living between 16.616.616.6 and 24.424.424.4 years.

what do u need to know

step-by-step explanation:

3/6 chance

step-by-step explanation:

half of the nubers are odd numbers (1,3,5) which in that case if you would be told to simplify it would be 1/2

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629

the argument of alfred t. mahan, henry cabot lodge, and albert j. beveridge was the economically and mass production the the americans could not consume themselves. this led expansion to sell to other foreign nations for profits.
