So lets do it like this:
z = (X-Mean)/SD 
<span>z1 = (8-12)/2 = - 2 </span>
<span>z2 = (16-12)/2 = + 2 </span>
<span>According to the Empirical Rule 68-95-99.7 </span>
<span>Mean more or less 2SD covers 95% of the values </span>
So t<span>he percentage of data points falling between 8 and 16 = 95%
</span>I hope this can help

In a school egg drop challenge 136 of the eggs broke out of 200 total what percent of eggs survived the drop ?
dusya [7]

To make this equation easier, we can just divide the data by 2, so that the exact number of eggs that survived, is the percentage that survived.

Explanation:

200 = 200    Total Eggs

136  = 136   Eggs That Broke

So, the ratio of eggs that broke to total eggs is:

136 / 200

So, subtract the number of eggs that broke to the total eggs, to find the amount that survived.

200 - 136 = 64

So now we know that, 64 eggs of 200 survived.

Which means, that 32% off the eggs had survived.

Answer:

see explanation

Step-by-step explanation:

Given

(2m + 5n)² = (2m + 5n)(2m + 5n)

Each term in the second factor is multiplied by each term in the first factor, that is

2m(2m + 5n) + 5n(2m + 5n) ← distribute both parenthesis

= 4m² + 10mn + 10mn + 25n² ← collect like terms

= 4m² + 20mn + 25n² ← perfect square trinomial
