Answer:
7/8 is greater than 2/4
Step-by-step explanation:
2/4 is 50% or 0.5 decimal
7/8 is 87.5% or 0.875 decimal
Answer:
0.8
Step-by-step explanation:
The question here says that In a class of 30 students, 18 are men, 6 are earning a B, and no men are earning a B. If a student is randomly selected from the class, find the probability that the student is a man or earning a B.
Since the question says that 18 out of 30 students are men,6 out of the remaining people earn a "B" and non of the 18 men earn a "B".
The probability of picking a man or a person that earns a "B" is
18/30 (since there are 18 men out of the 30 students)
And 6/30(since there are 6 people that earn a "b")
The probability of picking a man or a "b" earner is
18/30 + 6/30
= 24/30 or 0.8

Answer:
D) ± .0207
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 width of the interval is given by the following formula:
In a random sample of 810 women employees, it is found that 81 would prefer working for a female boss.
This means that
95% confidence level
So , z is the value of Z that has a pvalue of , so .
The width of the 95% confidence interval for the proportion of women who prefer a female boss is
So the correct answer is:
D) ± .0207
Answer:
x = 20
Step-by-step explanation:
100 + 3x + x = 180
100 + 4x = 180
- 100 -100
4x = 80
÷4 ÷4
x = 20
360° is a full circle, and since this is half you set the numbers equal to 180°
I hope this helps!
