The way I would do it is by rounding 8.91 up to 9 and I would round 34,871.081 up to 35,000.
9*35,000=315,000
Hopefully I was able to help in some way.
Answer:
r = 0.99
Very strong positive correlation between x and y
Step-by-step explanation:
Given is a data containing years and the corresponding heights
We have to find the correlation coefficient.
x y
1 2.1
2 3.2
3 6.8
4 7.3
5 11.2
6 12.6
7 13.4
8 15.9
r 0.988670694
Formula for r is
Thus we find that correlation coefficient is 0.988670694
Rounding off to two decimals r = 0.99
Very strong positive correlation between x and y
Answer:
By graphing the line, we have the equation y =
Step-by-step explanation:
What this question is asking us is to find the equation of the line with the value of the slope given in the question and also passing through the point in the question
For a straight line, the general equation can be represented as
y = mx + c
where m is the slope of the line and c is the y intercept. From the question, we have the value of the slope, what we have left to find is the value of the intercept. We find this by inserting the x, y and the slope value into the general equation of a straight line.
We have;
-3 = 3/4(2) + c
c = -3 - 6/4
c = -3-1.5 = -4.5
Thus, the equation of the line is;
y =
Yes 3/11 is greater than 3/13
Answer:
12
Step-by-step explanation:
The cost for n attendees will be ...
cost = 2 + 2n
We want the cost to be, at most, 26, so we have ...
26 ≥ 2 +2n
Dividing by 2 gives ...
13 ≥ 1 + n
And subtracting 1, we find the answer:
12 ≥ n
At most, there can be 12 attendees.
