Answer:

10 degrees

Step-by-step explanation:

A straight line equals 180 degrees. We already know we have 110 degrees, so we subtract 180-110 and get 70. Now, we can set up an equation:

We have to isolate x, so divide both sides by 7

70=7x

_____ = 10=x

x=10 degrees

Hope this helps!

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

Hence, find the smallest possible value of z such that 160 x z is a perfect square

vodka [1.7K]

Answer:

10.

Step-by-step explanation:

I am assuming that z is a whole number.

160z = x^2

z = x^2/ 160.

160 = 2*2*2*2*2*5

To make this a perfect square we multiply by 2 * 5

- this gives us 1600.

z = 1600/160 = 10.
