The circle passes through the point (-1,8). What is it’s radius? Options: A: 3 B: √8 C: √6 D: 2.75

Jlenok [28]

Answer:

B √8

Step-by-step explanation:

Equation of a circle is:

(x − h)² + (y − k)² = r²

where (h, k) is the center and r is the radius.

The center of the circle is (1, 6).

(x − 1)² + (y − 6)² = r²

The circle passes through the point (-1, 8).

(-1 − 1)² + (8 − 6)² = r²

4 + 4 = r²

r = √8

The distribution of actual weights of 8-ounce wedges of cheddar cheese produced at a dairy is normal with mean 8.1 ounces and st

Brrunno [24]

The mean of the weight is 8.1 ounces.
So the means of the distribution of 10 sample will be 10*8.1.
And the mean of 20 cheese wedges is again 20*8.1.
(The mean of the addition of two normal law is the sum of the
mean of each law)
Divide the above two numbers: $\frac{20\times8.1}{10\times8.1}=2$

The distribution of the sample means of the weights of cheese wedges is multiplied by 2 in the new batches.
