Answer:
(D) 200 men and 2,000 women
Step-by-step explanation:
To have an approximately normal distribution for the difference between proportions, we have to have sample sizes that are big enough to satisfy this conditions:
For men, we have p=0.08, so we have:
The sample size for men has to be at least 125 individuals.
For women, we have p=0.005:
The sample size for women has to be at least 2000 individuals.
The option that satisfy the requirements for men and women is Option D, as the others don't have enough sample size for women.
Answer:
D. 6 1/12
Step-by-step explanation:
First add the like fractions.
3 2/3 + 2/3 = 3 4/3 (Don't worry about simplifying yet)
Now find the least common multiple for 3 4/3 and 1 3/4 so we can add them.
<h2>
REMEMBER: You can only add and subtract fractions when they have the same denominator.</h2>
3: 3, 6, 9, 12
4: 4, 8, 12
In this case 12 is the least common multiple.
3/4 x 3/3 = 9/12 9/12
4/3 x 4/4 = 16/12
Add those two fractions then add the whole numbers and put it in front.
4 25/12
Simplify
6 1/12
Answer:
0.1/4-3/20=1/40-6/40=-1/8 200% of this is -1/4

Answer:
They represent the rise and run of the graph.
Step-by-step explanation:
<em>The difference between the x-axis of the points represents the "run" of the graph (or how much you should run along x-axis to get to the next point.)</em>
<em>The difference between the y-axis of of the points represents the "rise" of the graph (or how much you should rise up the y-xis to get to the next point).</em>
The ratio of rise to run is the slope of the graph, which tells us how many steps should we take on the y-axis for every step we move forward on the x-axis.
