.186915888
that is the answer
if I meant 2.675 divided by .5 it is 5.35
Answer and explanation:
A negative correlation means a relationship between two variables whereby each variable affects the other such that an increase in one variable means a decrease in the other and vice versa. This is the situation with the correlation graph/scatter plot of Dr. Hotchkins: An increase in stress would cause a decrease in emotional well being and vice versa
An Outlier is a data point on the scatter plot that does not fall into the pattern of the correlation graph. From the above, 4 points are outliers: extremely high points on stress and emotional well being. These points would affect (increase or decrease) the correlation coefficient depending on where they fall in the pattern. In this case there are 4 outliers out of 60 data points and we know that the more outliers there are the more effect they have on the correlation coefficient and vice versa(also depending on where the outlier is on the scatter plot)
We should first calculate the average number of checks he wrote
per day. To do that, divide 169 by 365 (the number of days in a year) and you get (rounded) 0.463. This will be λ in our Poisson distribution. Our formula is
. We want to evaluate this formula for X≥1, so first we must evaluate our case at k=0.
To find P(X≥1), we find 1-P(X<1). Since the author cannot write a negative number of checks, this means we are finding 1-P(X=0). Therefore we have 1-0.3706=0.6294.
There is a 63% chance that the author will write a check on any given day in the year.<em />
Answer:
x intercept: 10
y intercept: -6
Step-by-step explanation:
x intercept: 10
y intercept: -6
8x + 7y =89
2x + 5y=45
You want to be able to subtract one away from the other one so you are just left with either x or y. to do this we could multiply the bottom equation by 4
so you would get
8x+7y=89
8x + 20y= 180
Now we can subtract equation 1 from equation 2 so you get
13y=91
this gives you y=7 so to find x we can simply substitute y into an equation;
2x + 5x7=45
2x + 35= 45
2x = 10
x =5
so the final answer is y = 7/ x = 5
