1/2 is less than 3/4 and larger than 1/4
Answer: 2245 lbs or 1.1225 tons
Step-by-step explanation:
1 ton = 2000 lbs
adult weighs 3 tons or 6000 pounds
so I took the 3 year olds weight of 3755 and subtracted that from the adults weight in pounds to find the total weight in pounds needed to become an adult
6000-3755 = 2245 lbs and if you want it in tons then divide by 2000
2245 / 2000 = 1.1225 tons
Answer:
21.0%
Step-by-step explanation:
Answer:
0.969
Step-by-step explanation:
Given that:
Mean lifetime (m) = 520 hours
Variance = 900
Hence, standard deviation (s) = √900 = 30
Probability that bulb will last for at most 576 hours
X ≤ 576
Obtain the standardized score :
Using the relation :
Zscore = (x - m) / s
Zscore = (576 - 520) / 30
Zscore = 56 / 30
Zscore = 1.867
P(Z ≤ 1.867) : using the z probability calculator ;
P(Z ≤ 1.867) = 0.96905
Hence, P(Z ≤ 1.867) = 0.969
Let x be the distance of the additional water stations from the starting line.
We want on that is 1.5 miles behind the 8-mile water station, and one that is 1.5 miles ahead. The following absolute value function describes x:
|x-1.5| = 8
Two numbers comply: x= 9.5 and 6.5.
The additional water stations will be 6.5 and 9.5 miles from the starting line.
