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:
C. The median for town A, 30°, is less than the median for town B.
Step-by-step explanation:
A box plot can clearly represent the median as a center of the distribution of a data set.
Thus, the median of a box plot is depicted by the vertical line that divides the rectangular box.
Therefore:
Town A Median temperature = 30°
Town B Median temperature = 40°
The standby that best compares their centers is:
C. "The median for town A, 30°, is less than the median for town B."
. The student's conclusion is incorrect because the solution to the system of equations 4x + 2y = 32 and 5x + 2y = 36 is (4, 8).
B is right option
4x + 2y = 32
5x + 2y = 36 subtracting
-x=-4
x=4
4(4)+2y=32
16+2y=32
2y=16
y=8
hope this helps
