We can do math with points like they were variables
H = (I + J)/2
2H = I + J
I = 2H - J
I = 2(1,0) - (-5,-4) = (2 + 5, 0 + 4) = (7, 4)
Answer: (7,4)
The correct answer is -27
Answer:
1. 14
2. 2.75
3. 7.25
4. 6.5
Step-by-step explanation:
1. You just make a dot plot and count the amount of dots there are.
2. You go to your dot plot and see the smallest amount and you get your answer.
3. Same thing as the smallest amount, except you just have to find the greatest amount.
4. You just find which number appears the most on the dot plot, and bam you got your answer.
Fill in x=1.7 gives f(1.7) = 0.5*1.7 ≈ 0.850
What we can say with a good deal of certainty is that our sample is biased towards the higher spectrum and that the real value of the mean for our population is lower than the obtained value of our sample. If this is true, we should expect for the standard deviation to be higher than in the population.
