Answer: 0.4667
Step-by-step explanation:
According to 68–95–99.7 rule , About 99.7% of all data values lies with in 3 standard deviations from population mean (
).
Here , margin of error = 3s , where s is standard deviation.
As per given , we have want our sample mean 
to estimate μ μ with an error of no more than 1.4 point in either direction.
If 99.7% of all samples give an within 1.4 , it means that
Divide boths ides by 3 , we get
Hence, So must have 0.4667 as standard deviation so that 99.7 % 99.7% of all samples give an within 1.4 point of μ .
Answer: In a week you can travel 941 miles
Step-by-step explanation:
$240+0.15m=$381
Subtract $240 on both sides:
$240-$240+0.15m=$381-$240
0.15m=$141
Divide 0.15 on both sides:
0.15m/0.15=141/0.15
m=941 miles
Answer:
D. r(t) = (10 + 12t, 5 + −34t, 6 + −6t)
Step-by-step explanation:
Hope this helps
When the lines are parallel and angles are given, and since a straight line is 180°, the 2 angles of the line intersecting the parallel lines have to add up to be 180. Therefore,
21. 31°
22. 96°
23. 149°
24. 84°
25. 53°
