Answer:
If the walking time is greater than or equal to 38.225 hours, than it exceeds 95% probability that is lie in top 5%.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 30 hours
Standard Deviation, σ = 5 hours
We are given that the distribution of waking time is a bell shaped distribution that is a normal distribution.
Formula:
We have to find the value of x such that the probability is 0.95
Calculation the value from standard normal z table, we have,
Thus, if the walking time is greater than or equal to 38.225 hours, than it exceeds 95% probability that is lie in top 5%.
Answer:
38 more ounces.
Step-by-step explanation:
First, convert the 7 lbs. to ounces by multiplying 7 by 16. You do this because 1 pound equals 16 ounces. You get 112 ounces. Then subtract the hand's weight (74 oz.) from the piglet's weight (112 oz.). You get 38 ounces which is your answer.
Answer:
d = 6.1m
n = 7km
Step-by-step explanation:
To find the variables, use tan
⇒ tan = 
finding d:
⇒tan 63 = 
tan of 63 is 1.963
⇒ 1.963 =
multiply 3.1 on both sides
⇒ 1.963 x 3.1 = x 3.1
⇒ 6.0853 = d
round to the nearest tenth:
⇒ 6.0853 = 6.1
finding n:
⇒ tan 45 = 
tan of 45 is 1
⇒ 1 =
multiply 7 on both sides:
⇒ 1 x 7 = x 7
7 = n
Answer:
7. 2355 m
8. 1570 km
9. 157 cm
10. 40.82 m
Step-by-step explanation:
The circumference of a circle is pi * diameter or 2 * pi * radius.
If you are given the diameter, just multiply it by pi, 3.14.
If you are given the radius, then multiply the radius by 2 and then by pi, 3.14.
7. d = 750 m
circumference = pi * d = 3.14 * 750 m = 2355 m
8. d = 500 km
circumference = pi * d = 3.14 * 500 km = 1570 km
9. r = 25 cm
circumference = 2(pi)r = 2 * 3.14 * 25 cm = 157 cm
10. r = 6.5 m
circumference = 2(pi)r = 2 * 3.14 * 6.5 m = 40.82 m
So, x > 7 - 2; x >5 or
4 - x > 6; 4 - x - 6 > 0;
4 - 6 -x > 0;
- 2 -x > 0;
-2 > x;
Finally, x > 5 or x < -2;
