Answer:
Option c:
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 z-score that has a p-value of .
For this problem, we have that:
You have access to first year enrolment records and you decide to randomly sample 119 of those records. You find that 89 of those sampled went on to complete their degree. This means that .
90% confidence level
So , z is the value of Z that has a p-value of , so .
Sample of 90 people with a sample proportion of 0.25
This means that .
Confidence interval:
Which is option c.
Answer:
572 is evenly divisible by:
1 2 4 11 13 22 26 44 52 143 286 572
It is not a prime number.
Step-by-step explanation:
Answer:
2/3
Step-by-step explanation:
A line perpendicular to another line has a opposite reciprocal slope.
For example, if a line has a slope of 5, then the perpendicular line will have a slope of -1/5.
First, put the formula into slope intercept form:
3x + 2y = 18
2y = -3x + 18
y = -3/2x + 9
Because this line has a slope of -3/2, the perpendicular line will have a slope of 2/3.
It would most likely be B. :)
Answer:
B. Area C is the sum of the areas of A and B
Step-by-step explanation:
This is an illustration of the Pythagorean theorem. The number of squares in C (25) is the total of the numbers of squares in A (16) and B (9).
