Point estimate for the difference between two population proportions is the difference between the two sample proportions, written as:

and the standard deviation is given by

When np and n(1-p) is greater than 5, then the sampling distribution is approximately normal and we can use standard normal methods.
Thus, the propability of a test <span>for the difference between two population proportions is given by

One equation that you could make is 5+2-(-3)
Answer:
173.83
Step-by-step explanation:
17.4*9.99= 173.826
173.826 -> 173.83
A typical towel is the shape of a rectangle.
Rectangles have 2 opposite pairs of congruent (equal) sides.
To find perimeter, find the sums of all the sides.
The measures of the towel's sides are:
2 feet
2 feet
3/4 foot
3/4 foot
Add these together to find the perimeter.
2 + 2 + 0.75 + 0.75 = 5.5
The perimeter of the towel is 5.5 feet.
Hope this helps!

Answer: The missing length is 120 {option C}
Step-by-step explanation: What we have in the question is a triangle placed on top of another triangle and as shown in the attached diagram we can separate them into triangles BFC and GFH.
A close observation shows that line BC is parallel to line GH. Hence we have two similar triangles, and we can determine their similarity ratios as follows;
BF/FC = GF/FH
Similarly BF/BC = GF/GH
We can also express the following ratio
FC/FH = BC/GH
Therefore to calculate the missing side, which is GF, we can use the ratio
FC/FH = FB/FG
30/100 = 36/FG
By cross multiplication we now have 30 (FG) = 100 (36)
30FG = 3600
Divide both sides of the equation by 30
FG = 120
