To answer the ratio, massage this equation around to find ' n/m ' .
Let's subtract 'm' from each side:
4n = 2n + 7m
Subtract '2n' from each side:
2n = 7m
Divide each side by 'm' :2 (n/m) = 7
Divide each side by 2 :
n/m = 7/2 . . . . . there's your ratio. That's choice-'e'.

The average birth weight of elephants is 200 pounds. Assume that the distribution of birth weights is Normal with a standard dev

zhenek [66]

The birth weight of elephants at the 85th percentile is 262.16 pounds

<h3>What is the standard deviation?</h3>

Standard deviation is defined as the amount of variation or the deviation of the numbers from each other.

Given that:-

The average birth weight of elephants is 200 pounds $\mu$ = 200

The deviation of 60 pounds. $\sigma$ = 60

The birth weight of elephants at the 85th percentile. z = 85%= 1.036

Now from the formula of z-score:-

$z=\dfrac{x-\mu}{\sigma}\\\\\\z=\dfrac{x-200}{60}\\\\\\1.036\times 60=x-200\\\\\\x=\ \ 262.16\ pounds$

Hence the birth weight of elephants at the 85th percentile is 262.16 pounds
