Answer:
Both of them can be simplified.
Recall that 4 = 2^2.
2^7 / 4^2 = 2^7 / (2^2)^2 = 2^7 / 2^4 = 2^(7-4) = 2^3 = 8
Similarly, 2^7 / 2^4 = 2^(7-4) = 2^3 = 8
The answers to both exercises are 8.
Answer: the IQR is 3.5
Step-by-step explanation:
Answer:
B. infinite solutions along a line
Step-by-step explanation:
The matrix is equivalent to the equations ...
x = 2
y = 9
0z = 0 . . . . . . true for any z
This tells you the solutions are ...
(x, y, z) = (2, 9, z)
This defines a line parallel to the z-axis.
7/10 = 0.70(7 divided by 10)
3/5 = 0.60(3 divided by 5)
9/11 = 0.81(9 divided by 11)
1/2 = 0.50 (1 divided by 2)
Answer: 9/11
