Answer:
The data speed 1.4Mbps is in the 34th percentile.
Step-by-step explanation:
To find the percentile of a value X in a data set, we divide the number of values lesser than X in the data set by the total number of values in the data set, and then multiply by 100.
In this set
There are 17 values lesser than 1.4
There are 50 values in all.
So
The data speed 1.4Mbps is in the 34th percentile.
I would say C, but not sure :)
Answer:
The y intercept is -1 and the slope is 4/1
Step-by-step explanation:
When you are trying to find the y-intercept, you look at where the line crosses over the y axis. In this case it was at -1.
The slope indicates how many units it is going up/down or left/right. In this case, the distance between each point is up 4, and right 1. so the slope would be 4/1.
I hope this helps :)
Answer:
-1
Step-by-step explanation:
f(x) =2/3x -5
Let x = 6
f(6) = 2/3 (6) - 5
Multiply first
f(6) = 12/3 -5
= 4-5
= -1
Okay, here we have this:
Considering the provided information, we are going to calculate the requested value, so we obtain the following:
Then we will substitute in the following formula:
Students who play soccer=Number of students*(Probability that they play soccer)
Replacing:
Students who play soccer=300*(12/25)
Students who play soccer=3600/25
Students who play soccer=144
Finally we obtain that 144 students would we expect to play soccer, based on Sean's experiment.
