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

natulia [17]

Answer:

distance is 11.3137 units

Step-by-step explanation:

$\sqrt{( - 4 -2) ^{2} + (3 - - 5) ^{2} } \\ \sqrt{64 + 64} \\ \sqrt{128 } \\ \sqrt{2 \times 64} \\ \sqrt{2} \times \sqrt{64} \\ 8 \sqrt{2} \: units \\ 11.3137 \: units$

hopefully it makes sense
