What is the first error she made in computing the variance? emi failed to find the difference of 89 - 78 correctly. emi divided
by n - 1 instead of n. emi evaluated (46 - 78)2 as -(32)2. emi forgot to take the square root of -135.6.

The first error Emi made in computing the variance is failing to find the difference of 89 - 78 correctly.
<h3>What is Mean?</h3>
This is defined as the average of the given numbers and is calculated by dividing the sum of given numbers by the total number of numbers.
In this case , sum of given numbers = 87+46+90+78+89 = 390
Divide 390 by the number of numbers which is = 5
390/5 = 78
Therefore Emi failed to find the difference.

Step-by-step explanation:
Answer:The surface area of the cube is 100 cm.
Step-by-step explanation:
So since a cube has six faces and all of its lengths are equal. we could use the equation.
10^2 *6= 100 *6= 600
Ya have to round it to the nearest hundred, so that would be 2 thousand.
so it's 4,552,000
If you're looking for the angle it is a 30, 60, 90, but if you're looking for the length of the hypotenuse it's 5
