Answer:
114
Step-by-step explanation:
so lets call shelf 1 x
shelf 2 is twice size + 18 of shelf 1 so it is 2(x)+18
shelf 3 is 12 less than shelf 1 so x-12
shelf 4 is four more so x+4
Add them all together and it should be 5x+10= 2.5 m or 250 cm
Solve for x using cm
then plug into shelf 2 equation
Answer:
- 0.167 < 0.5 ≤ 1.167
means 1/2 is -0.167 less
and 1/2 is equal to 1.167 when 2/3 is set to distance each way.
Step-by-step explanation:
we can evaluate what 2/3 equals by equating the number to decimal
0.33 = 1/3 so 0.667 = 2/3
We then just subtract and add to 1/2
0.5 + 0.667 = 1..167
0.5 - 0.667 = -0.167
The answer at least i think is a
His mistake was that he did not use a random sample. His tried to show that playing games would give him higher grades which his study does not decisively conclude because the people around him that play games are likely to be in the same academic caste as him, which skews his data. Choice B would be the best because he's not testing any variables, rather just collecting the unadultered data of the group.
