Answer:
Step-by-step explanation:
Given that:
population mean = 10
variance = 25 ; = = 5
sample size n = 28
The standard deviation of the sample mean:
=
= 0.95
To halve the standard deviation of the sample mean, the size of how large the sample will be can be computed as follows:
= 2
n = 4 × 28
n = 112
Answer:
y = -8
Step-by-step explanation:
Use reverse operations to isolate the variable, y.
y = -8
your average mean score would be <u>C. 85</u>
Answer and Step-by-step explanation:
<u>The answer is 42°.</u>

This is because we are given an Isosceles Triangle. Isosceles Triangles always have 2 legs/sides that are the same length, and because those two sides have the same length, it means their base angles have the same value as well.
So, Since the angles LKM and KML are the base pairs of this Isosceles Triangle, they are equal to each other.

Ok so...
You want to move the decimal point to the right until the number is greater than 1 but less than 10.
The number will end up being 5.2
You moved the decimal point 3 times to the right.
So it will be 5.2 x 10^-3. It is negative because you moved it to the right. The exponent would be positive if you moved it to the left
