Answer:
0.0273
Step-by-step explanation:
np n
10 100
9 100
11 100
7 100
3 100
12 100
8 100
4 100
6 100
11 100
pbar=sumnp/sumn
pbar=10+9+11+7+3+12+8+4+6+11/10+10+10+10+10+10+10+10+10+10
pbar=81/1000
pbar=0.081
nbar=sumn/k=1000/10=100




Standard deviation for p-chart=0.0273
So the ration is 1 to 5 since it's one foot every 5 seconds. So for every 5 seconds, add 1 foot.
For example: in 45 seconds, it would travel 7 feet.
But in this Scenario, the timer starts after 5 feet so just add 5
Ex. in 45 seconds, it would have traveled 12 feet since we added the 5 feet that we started with to the 7 other feet it traveled.
Idk If this will help very much but I hope it does.
B and C. This problem comes down to equal fractions, so B is 2/3 and C is 1/1.5. And 2/3=1/1.5. So they are correct
Answer:The area of the bottom of the jewelry box is 139.75 inch^2
Step-by-step explanation:
The area of a rectangle is expressed as
Area = Length × width
The length of the rectangular bottom of dais jewelry box is 5 3/8 inch. Converting to improper fraction, it becomes 43/8 inch.
The width of the rectangular bottom of dais jewelry box is 3 1/4 inch. Converting to improper fraction, it becomes 13/4 inch.
The area of the bottom of the jewelry box will be
43/8 × 13/4 = 559/32 = 139.75
