Answer:
842 rounded to the nearest ten is 840
Step-by-step explanation:
Answer with explanation:
<u>Part A: </u>
One solution.
The number of points of intersection represents the number of solutions. Since the two lines only intersect at one point, there is only one solution.
<u>Part B:</u>
(3, 4)
The point(s) of intersection marks the solution(s) to the lines. Since lines A and B intersect at the point (3, 4), the solution to the equation of their lines is (3, 4), or
, as coordinates are written as (x, y).
Answer:
The equation of the regression line for the following data is:
y=2.4x+120.1
Step-by-step explanation:
We are given a set of data values in table form as:
Day(x) Number of visitors(y)
1 120
2 124
3 130
4 131
5 135
6 132
7 135
Hence, when we draw a scatter plot with the help of these data points using the linear regression calculator we see that the regression line is a line with y-intercept as (0,120.1) and x-intercept as (-50.04,0)
Hence, the regression line for the following data is:
y=2.4x+120.1
I hope this helps.....

I took this in 9th grade so I know how to do this kind of stuff
We are given that the titanic is found 3,797 m below sea
level. This is simply equivalent to 3.797 km or 3.8 km when rounded off to one
decimal.
We should take note that the letter k in km means kilo and
a kilo is equivalent to 1000. So this means that for 1 km there is exactly 1000
m. So to convert, simply multiply a value with unit m with this conversion
factor. Conversion factor = 1 km / 1000 m
Depth of titanic = 3,797 m (1 km / 1000 m)
<span>Depth of titanic = 3.797 km = 3.8 km</span>
