Answer:
x = 7 and y = 17
Step-by-step explanation:
16x + 9x + 5 = 180 cuz they are supplementary
25x = 175
x = 7
We also know that 16x + 4y = 180
so 16(7) + 4y = 180, so 4y = 180 - 112, so 4y = 68. y = 17
hope this makes sense
Answer:
I am pretty sure the answer would be A.
1/2 of 20 is 20/2 which is 10.
All you really need to do here is to divide 20 by 2 to get 10.
By definition, an absolute frequency is the measure of how frequently an event occurs based on data from an experiment of survey.
This frequency is independent of what the other events in the experiment are and thus is termed absolute frequency.
Thus, for the given question, option B, absolute frequency is the correct option.
Answer:
x^2 -4x +4
Step-by-step explanation:
(x-2)(x-2)
x^2 -2x -2x +4
x^2 -4x +4
