4 pencils . 4/9 of an hour = 4/9 of 60 minutes = 4/9 * 60 = 80/3 minutes
x pencils = ? . one hour = 60 minutes
14 * 60 = 80/3 * x /*3
14 * 60 * 3 = 80 * x
80 * x = 2520 /80
x = 2520 / 80
x = 31.5 pencils
The result would be 32 pencils in one hour.
Answer:
14%
Step-by-step explanation:
First find the total for all the dresses.
Total = 14 + 37 + 22 + 56 + 33
Total = 162
Now you are concerned about the blue dresses.
% = (22 / 162) * 100 = 13.58 %
Rounded to the nearest % it would be 14%
The number of degrees it would occupy in the pie chart would be 360 * 14/100 = 49 degrees.
Answer:
A) 2.58
B) 1.96
C) 1.65
Step-by-step explanation:
A hypothesis used to test that
against the alternatives 
not equal to 10
if null hypothesis is true, then distribution of test statics follow
for two sided alternatives hypothesis 
, then P value is
![P = 2[1- \phi(\left | Zc \right |)]](https://tex.z-dn.net/?f=P%20%3D%202%5B1-%20%5Cphi%28%5Cleft%20%7C%20Zc%20%5Cright%20%7C%29%5D%20)

C) significance level 
from 1 eq we get
Therefore 
FROM Z TABLE
Answer: 1 over 2 (1/2)
Simplify 2 over 8 to get 1 over 4. Now you have 1 over 4 divided by 1 over 2. Whenever you divide with fractions you flip the fraction and multiply . So it becomes 1 over 4 multiplied by 2 over 1.
2/8 (divided by) 1/2
1/4 (divided by) 1/2
1/4 x 2/1
= 1/2
