Answer:
The correct option is: The college spread is best described by the standard deviation. The high school spread is best described by the IQR.
Step-by-step explanation:
We have given a table. According to that table a survey about the amount of time students spend doing homework each week has been conducted. The students were either in college or in high school. Now which of the choices below best describes how to measure the spread of this data.
The correct option is: The college spread is best described by the standard deviation. The high school spread is best described by the IQR.
Answer:
its a)the first sequence is geometric bc of the common ratio of 2. the second sequence is arithmetic bc of the common difference of 7.
you have the following inequality:
3 + 4x > -5
in order to solve for x, proceed as follow:
3 + 4x > -5 subtract 3 both sides
4x > - 5 - 3
4x > -8 divide by 4 both sides
x > -8/4
x > -2
Hence, the solution to the given inequality is x > -2
Answer:
60 seconds, 7715 feet
Step-by-step explanation:
Plane A and B start out 615 feet apart, and we find this by subtracting the height of plane A from plane B, getting 5000-4385=615. Now we have to find how many more feet of altitude plane A is gaining per second over plane B.
To find this we subtract 45.25 from 55.5 and get 10.25 feet per second. Now to find out how many seconds until they'll be at the same altitude we simply divide 615 by 10.25, getting 60 seconds.
For the second part, to find the altitude at this point, we simply multiply the altitude gain of one of the planes per second by the time of 60 seconds to get how much altitude they gained over that time, and add it to the starting altitude. Doing this with plane B we get 45.25*60=2715, and we add that to 5000 to get the final answer of 7715.
Answer:
2244.9
Step-by-step explanation:
Anually compound interest formula
PV(1+i)^t
1800(1+.0375)^6
1800*1.0375^6
2244.921387 which rounds to
2244.9
