Complete Question:
Chapter 6, Section 1-D, Exercise 009 Is a Normal Distribution Appropriate? In each case below, is the sample size large enough so that the sample proportions follow a normal distribution?
a) n=600 p=0.2
b) n=20, p=0.4
if np=10 and npq=10 then the data follows normal distribution
a) np= 120,
q= 1-0.2= 0.8
npq= 600 ×0.2×0.4 = 48
Normal distribution is appropriate and sample size is large enough
b) np= 8
q= 1-0.4= 0.6
npq= 20 × 0.4×0.6= 4.8
sample size is not large enough so normal distribution is not appropriate.

Answer:
14.9 cm
Step-by-step explanation:
To find c using the Law of Sines, you must know angle C. That is found from ...
C = 180° -A -B = 180° -150° -12° = 18°
Then the law of sines tells you ...
c/sin(C) = b/sin(B)
c = b·sin(C)/sin(B) = (10 cm)·sin(18°)/sin(12°)
c ≈ 14.9 cm
12 because the rest of the numbers are all similar except 12
Answer:
10 centimeter=92 milimeter
Step-by-step explanation:
we know that
one centimeter contains 10 milimeter or
1 centimeter is equal to 10 milimeter
1 centimeter=10 milimeter
we have to find
how many milimetersare there in 9.2 milimeters
9.2 centimeter=? milimeter
for this we will multiply by 9.2 on both sides
1 centimeter=10 milimeter
9.2 centimeter=10*(9.2)=92 milimeter
10 centimeter=92 milimeter
