The question is not complete so I will answer it with an example and a few assumptions. Follow the steps to find the answer to your question.
Important to note:
Your question is a z-scores problem
Assume that for the population of unemployed individuals the population standard deviation is 4 weeks.
Thus, we need to find the z-value.
The z-value is the sample mean decreased by the population mean, divided by the standard deviation that we assumed. So, we have:
Using any standard negative z-scores table, we can find that:
Thus, we get:
Therefore, the probability that a simple random sample of 60 unemployed individuals will provide a sample mean within 1 week of the population mean is 0.9476
Answer:
0.9476
Seeing as standard form is the typical way we see numbers, we can look at this problem as 800+200. Therefore, the correct answer would be 1,000.
To write this in standard form, you need to eliminate the
fraction in the coefficient of variable x. You can do this by multiplying 8 to
the two sides of the equation:
8(y) = 8[(-5/8)x + 3]
8y = -5x + 24
Transpose the variable x to the other side:
5x + 8y = 24

1st option?
Step-by-step explanation:
is there more part for the question?
The equation of the circle that passes through the point (0 , 4) and has a center at the origin is x^2 + y^2 = 16.
Using the distance formula, get the radius of the circle by solving for the distance between the center and the point (0 , 4).
radius = distance = √(x2 - x1)^2 + (y2 - y1)^2
radius = √(0 - 0)^2 + (4 - 0)^2
radius= √0 + 16
radius = 4
The standard form of the equation of the circle is given by (x - h)^2 + (y - k)^2 = r^2, where (h , k) is the location of the center and r is the radius of the circle.
Given the radius and center of the circle, substitute these values to the standard form of the equation of the circle.
(x - h)^2 + (y - k)^2 = r^2
where (h , k) = (0 , 0)
r = 4
(x - 0)^2 + (y - 0)^2 = 4^2
x^2 + y^2 = 16
