Answer:
0.1007
Step-by-step explanation:
Given :
Average gain, μ = 0.8
Standard deviation, σ = 0.7
Number of companies, n = 20
Obtaining the standardized value ;
Zscore = (x - mean) / (σ/√n)
Zscore = (1 - 0.8) / (0.7/√20)
Zscore = (0.2 / 0.1565247)
Z = 1.27775
Using the Z probability calculator :
P(Z > 1.27775) = 0.10067
P(Z > 1.27775) = 0.1007 ( Z probability calculator)
Answer:
true
Step-by-step explanation:
Answer:
a) 
b)
When d = 3
n = (3+2)/4 = 5/4 inches
When d= 6
n = (6+2)/4 = 2 inches
When d = 10
n = (10+2)/4 = 3 inches
Step-by-step explanation:
<u>Complete Question:</u>
<em>The penny size of a nail indicates the length of the nail. The penny size d is given by the literal equation d=4n−2, where n is the length (in inches) of the nail.</em>
<em>a) Solve equation for n</em>
<em>b) Use part (a) to find length of nails with the following penny sizes: 3, 6, 10.</em>
<u>Solution:</u>
<u />
a)
We use algebra and take 2 to the other side and divide to solve for n. Shown below:

So,
n = (d+2)/4
b)
Since we have to find length of nails, we plug in 3, 6, and 10 respectively into d of the formula we found in part (a).
When d = 3
n = (3+2)/4 = 5/4 inches
When d= 6
n = (6+2)/4 = 2 inches
When d = 10
n = (10+2)/4 = 3 inches
