You start by adding the integer:
39+75+120+50 =284
What you have left: 1/2, 1/3, 1/6
Make the 1/3 to 1/6:
1 (•1)/3 (•2) = 1/6
1 (•2)/6 (•1) = 2/6
1/6 + 2/6 = 3/6 = 1/2
1/2 + 1/2 = 1
284+1
285 feet • $5 = $1425
Answer:
a) n = 1037.
b) n = 1026.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of
The margin of error is:
99% confidence level
So , z is the value of Z that has a pvalue of , so .
(a) Assume that nothing is known about the percentage to be estimated.
We need to find n when M = 0.04.
We dont know the percentage to be estimated, so we use , which is when we are going to need the largest sample size.
Rounding up
n = 1037.
(b) Assume prior studies have shown that about 55% of full-time students earn bachelor's degrees in four years or less.
So
Rounding up
n = 1026.
LINE A
y-intercept : 3
x-intercept: 3
Rate of change: x (because 3/3 equals 1 and 1 times x is the same as x by itself)
Line B
y-intercept: 2
x intercept: -2
rate of change : x (because 1/1 is 1 and 1 times x is the same as x by itself)
Line C
y-intercept: -4
x intercept: 2
rate of change: 2
Line A: Equation F
Line B: Equation D
Line C: Equation E
Extra Notes:
y=mx + b is the slope intercept equation.
M is the slope
B is the y intercept
X and Y are the coordinates
To find slope, you can always use y2-y1/x2-x1 or even determine the slope on the graph by using rise over run and simplifying when possible.

Answer:
First we multiply to see how many she has gotten, which is the equation 5x4 and that equals 20. Now we see how many she has lost. She has lost a total of six, we count this by subtracting 1/2 each time. The correct answer is 16.
Let me know if this helped, :-D
