Answer:
n=3.8416≅4
So Minimum Sample Size is 4
Step-by-step explanation:
In order to find the minimum sample size, the formula we use will be:
Where:
n is sample size
Z is the distribution
S is the standard deviation
E is the Margin of error
S=3 ,E=3
For Z:
Alpha=1-0.95=0.05
Alpha/2=0.025=2.5%
From Cumulative Standard Distribution Table:
Z at Alpha/2 = 1.960
n=3.8416≅4
So Minimum Sample Size is 4
If a candy bar is cut into 8 pieces what is the ratio of the first 3 pieces to the rest of the pieces.
Answer: 3:8
Maybe hope it helps lol:)
This is in fact a polynomial of degree 7 since 7 is the highest exponent. Written correctly, these would be in order from highest degree to lowest. The coefficient (or number) that goes with the 7th degree term is a 6.
They should be points (-1.5, 0), (-6, 9), and (3, -9).
Answer:
Step-by-step explanation:
The formula to find the area of a triangle:
Here, 
is the area, 
is the base and 
is the height.
However, we are looking for height, so let's rearrange the equation for :
Now we know the formula to find the height, let's do so:
Therefore, our final answer is .
