The sample size should be 73.
We use the formula
To find the z-score:
Convert 95% to a decimal: 0.95
Subtract from 1: 1-0.95 = 0.05
Divide by 2: 0.05/2 = 0.025
Subtract from 1: 1-0.025 = 0.975
Using a z-table (http://www.z-table.com) we see that this value goes with a z-score of 1.96. Using this, our value for σ and our margin of error, we have:
The coordinate should be (4,5)
Answer:
From greatest to least
One and five-sixth rounded to 2
One and StartFraction 7 over 29 rounded to 1
0.16 rounded to 0
Step-by-step explanation:
1+7/29=29+7/29
=36/29
=1.24
Approximately
=1
1+5/6=6+5/6
=11/6
=1.83
Approximately
=2
0.16
Approximately =0
From greatest to least
One and five-sixth rounded to 2
One and StartFraction 7 over 29 rounded to 1
0.16 rounded to 0
Answer:
net force is the force used to push or pull the box
Step-by-step explanation:
for example-
==> 15N BOX 12N <==
15-12=3
3N
if they point the same way add if they point the opposite subtract
Find Q
- tanQ=Perpendicular/Base
- tanQ=4/15
- tanQ=0.26
- Q=tan^-¹(0.26)
- Q=14.6°
Not safe
Apply Pythagorean theorem
PR²=4²+15²=16+225=241
