Answer:
9.45
Step-by-step explanation:
6 2/6 = 6.3
1 1/2 = 1.5
6.3 * 1.5 = 9.45
9.45
Answer: 5
Explanation: The square root of 100 is 10. The square root of 4 is 2.
10/2 = 5
Answer:
x= 7
B= 112
F= 68
Step-by-step explanation:
to find x we set up an equation, (16x)=(4x+84). They are alternate interior angles which are always equal.
calculate it and you'll find x=7.
B and the angle 4x+84 are equal because they are vertical angles, to find it we just put 7 instead of x into 4x+84.
4(7)+84=112
angle f is supplementary to 16x. 16x is also 112 because they are equal, so its just 180-112=68
Answer:
My kids are dead
Step-by-step explanation:
Answer:
465
Step-by-step explanation:
Margin of error = critical value × standard error
ME = CV × SE
Assuming 95% confidence, CV = z = 1.96.
Standard error is:
SE = σ / √n
SE = 3.3 / √n
Given margin of error of 0.3:
0.3 = 1.96 × 3.3 / √n
n = 465
