Answer:
x=12
Step-by-step explanation:
63+8x-17+3x+2=180
48+11x=180
11x=132
132/11=12
The answer is sometimes, but this is only when the chord passes through the centermost point on the circle.
Hope this helps!
Answer:
No
Step-by-step explanation:
We have:
n = 80,
p = 0.1 (10%)
q = 1 - p = 1 - 0.1 = 0.9
Usually we use
np > 5, and nq > 5, but this question is using
np > 10, so we'll use that. It means that the proportion times the sample size must be greater than 10, we have
80(0.1) = 8 and
80(0.9) = 72,
since we got 8 as one answer, the situation doesn't hold up.
A, 3.2*10^5 would be the largest because it is the largest number with the largest exponent
