Answer:
2/3
Step-by-step explanation:
slope = change in y / change in x = (-7-(-1))/(-5-4) = (-6)/(-9) = 2/3
It's a Octagon!!!!!!!!!!!!
Answer:
D. 48
Step-by-step explanation:
Let's first find the probability that in the first 40 trials, exactly two of the coins are heads.
We know that there were 16 such outcomes of 2 heads and 1 tail, and there was a total of 40 possible outcomes. So our probability is:
16 / 40 = 4 / 10 = 2/5
We can assume that the probability that in the next 120 trials, about 2/5 of the outcomes will also be 2 heads and 1 tail. So, we multiply 2/5 by 120 to figure out that exact number:
(2/5) * 120 = 240/5 = 48
The answer is thus D.
<span>When doing linear regression, if the correlation coefficient is Negative, the slope of the line is Negative .
</span><span>When doing linear regression, if the correlation coefficient is positive, the slope of the line is positive.
So according to above explanation it is TRUE</span>
Answer: they’re both in the 4:3 ratio
Step-by-step explanation:
4:3 = 8:6 = 12:9 = 16:12 = 20:15 = 24:18 = 28:21 = 32:24 = 36:27 = 40:30, etc
