Answer:
3.75 hours
Step-by-step explanation:
Given data
DIstance driven from Gary, Indiana to Indianapolis= 160 mile
Time taken= 2 1/2 hours or 2.5 hours
Speed= distance/time
Speed= 160/2.5
Speed= 64 miles per hours
We want to find the time it will take to drive 240 miles at the same speed
Time= distance/speed
Time= 240/64
Time= 3.75 hours
Answer:
(14, 22)
Explanation:
The amount of time that customers have to wait for their food is normally distributed with:
• Mean = 18 minutes
,
• Standard deviation = 4 minutes.
The Empirical Rule
For normal distributions, the empirical rule states that:
• 68% of observed data points will lie inside one standard deviation of the mean.
,
• 95% will fall within two standard deviations
,
• 99.7% will occur within three standard deviations.
By the empirical rule, 68% of observed data points will lie inside one standard deviation of the mean.
Therefore, the interval of minutes that the middle 68% of customers have to wait is:
The interval is (14, 22).
Answer:
Step-by-step explanation:
To begin lets say year one the population is 2,000
assume this in percent we can say that 2,000=100%
at the end of this year the population will have grown by 4% meaning that
100%+4% will be the new population =104%
but we know that 100%=2,000 so what about 104%=X?
so (104*2000)/100=2,080
So year 1 the population will have grown by 80 people amounting to 2080 people.
Now do it manually year by year until we reach the 15th year. i will help you up to year 3
2nd year= (2080*104)/100=2163.2
3rd year= (2163*104)/100=2249.728
