Answer:
With the answer choices:
A. 11 + 8
B. 11 + 12
C. 28 + 12
D. 28 + 32
The answer would be 28+32.
Step-by-step explanation:
Use the distributive law.
4 * 7 = 28
4 * 8 = 32

By direct computation, arctan(0) = 0, arccot(0) = pi/2, arctan(1) = arccot(1) = pi/4.
Let a = arctan(sqrt(2)). Then cot(3*pi/2 - a) = cot(pi/2 - a) = tan(a) = sqrt(2), so arccot(sqrt(2)) = 3*pi/2 - a. Therefore, arctan(sqrt(2)) + arccot(sqrt(2)) = 3*pi/2.
Similarly, arctan(sqrt(3)) + arccot(sqrt(3)) = 3*pi/2.
So the answer is 0 + pi/2 + pi/4 + pi/4 + 3*pi/2 + 3*pi/2 = 4*pi.
The first one and the third set because the number 8 brackets appears with 4 and -6. Inorder to be a function the y values must be unique. The third set -2 repeats itself
Let x be the weight the kitten
z = (x- mean)/σ
1.22 = (x-3.1)/0.9
(1.22)(0.9) = x -3.1
and x = 4.198 pounds
