Answer:
Perpendicular ⇒
m = -1/-4 = 1/4
g(x) = (1/4)x + b
3/4 = (1/4)(5) + b
b = -1/2
g(x) = (1/4)x - 1/2
Step-by-step explanation:
3/4 times 3/4 is the same as 3/4 squared or (3/4)^2
To find the IQR you first need to write it in numerical order
77, 81, 83, 84, 86, 86, 88, 92
IQR is just Q3 - Q1
Q1 is the middle of the first have, since it has an even set of 4 numbers in the first half you need to take the average of the two middle ones.. which is 82
Q3 done the same process would be 87.
87 - 82 = 5
IQR = 5
40 is the answer =3 hope it works
The probability that 4 are chem majors would be 5%
