Answer:
383 students
Step-by-step explanation:
Average IQ = 115
So for IQ of 145 it's not average again.
So , 145 IQ should be 1/4 of the total number because it's no longer average .
So 1/4 of 1531 = 382.75 students approximately = 383 students
This answer is based on the assumption that average IQ is around 115.
So any one with IQ of 145 is not longer an average person concerning IQ.
Answer:
You're right its B or 35
Step-by-step explanation:
Just divide 140 by 4 u get 35

Answer:
Step-by-step explanation:
You will need to find the mean of 11, 13, 16, 17, 8, 10, 14, 14, 17, and 14. The mean of that is 134. When you get that, you divide that by 10 since that there are 10 numbers listed above. When you do that, you will get 13.4. When you get that, you subtract that to all the numbers above like the first one for example 11-13.4= |-2.4| = 2.4 and then so on. Here is the equations set up for you. You will have to find the answer yourself.
13-13.4= | | =
16-13.4= | | =
17-13.4= | | =
8-13.4= | | =
10-13.4= | | =
14-13.4= | | =
14-13.4= | | =
17-13.4= | | =
14-13.4= | | =
When you get all your answers for that you will have to divide that by 10 since that there are 10 again. When you get your answer, that will be you mean absolute deviation. For number 3, since if we get an answer that has 0.1, we can conclude that the amount of equations that are there listed for us has an amount more than the answers for these 13-13.4= | | = 16-13.4= | | = 17-13.4= | | = 8-13.4= | | = 10-13.4= | | = 14-13.4= | | = 14-13.4= | | = 17-13.4= | | = 14-13.4= | | = added all together.
The answer would be an Exponential Funtion.
I hope this helps love! :)
