Answer:
Yes
Step-by-step explanation:
Yes. Here's why: We can obtain the graph of the inverse of the function shown by reflecting the red graph about the line y = x. The resulting graph is true for all x values and for all y values; it passes the vertical line test.

Answer:
<em>A negative correlation is when one variable increse as the other decreases.</em> Is represented with a -1 value in contrast with +1 that represents positive correlations.
I hope you find this information useful and interesting! Good luck!
6x+8(-5)=22
6x -40 =22
6x= 22 +40
6x= 62
X= 62/6
X= 10.3
We are given frequency distribution in the question
to find the probability distribution from frequency distribution we need to divide frequency by total number of observations.
Here, total number of observations are 6+10+7+5=28
so , we will have probability distribution table as
X 0 1 2 3
P(x) .21 .35 .25 .17
probability distributiuon describes all possible values that a random variable can take within a given range.
frequency distribution is the presentation that presents number of observation in given interval.
