Answer:
np = 81 , nQ = 99
Step-by-step explanation:
Given:
X - B ( n = 180 , P = 0.45 )
Find:
Sampling distribution has an approximate normal distribution
Computation:
nP & nQ ≥ 5
np = n × p
np = 180 × 0.45
np = 81
nQ = n × (1-p)
nQ = 180 × ( 1 - 0.45 )
nQ = 99
1/4 miles in 1/8 hour
?mile in 1 hour
Step 1:
Cross Multiply
1×1/4=1/4
Step 2:
1/4÷1/8=2 miles. As a result,a person walks 2 miles in 1 hour. Hope it help!
1) P=2w +2l
46=2w +14
32=2w
16= w or width
2) A=lw
A=7 x 12
A= 84
3) A= 12 x 21
A= 252
