Answer:
I think the IQR is 100
Step-by-step explanation:
You would have to find the first and third quartiles first. After that you would subtract the third quartile by the first to get the IQR
Answer:
Step-by-step explanation:
The x intercepts are obtained by equating the factors to zero.
2x - 1 = 0
2x = 1
x = 1/2
2x - 5 = 0
2x = 5
x = 5/2
x = 2 1/2 or 2.5
The graph of f(x) = (2x -1)*(2x - 5) is given below. The x intercepts are labeled.
78 = -2(m + 3) + m
78 = -2m - 6 + m
78 = -m - 6 |add 6 to both sides
84 = -m
m = -84
0.377 + 5.51 = 5.887
Sorry I can only solve the first one. Could you give me a hint on how to do the second one ?
