Which table shows a negative correlation?

Answers

Answer 1

Answer:

If we graph the x - y values in a scatter plot and draw a line of best fit, we can easily see the solution.

Negative correlation means y decreases as x increases, or a negative sloping line.

Attached is the graphs of all the 4 choices. Clearly, the 4th table shows negative correlation.

ANSWER: Last table (4th table) shows negative correlation

Answer 2

Answer:

The table that shows negative correlation is the fourth table.

What is correlation?

Correlation is used in statistics to determine the relationship that exists between two variables.

Negative correlation means there is no relationship between the variables. When plotted on a graph, a negative correlation would be downward sloping. Looking at the tables, when plotted, only the fourth table would be downward sloping.

Chris earns four times Vesna's wage v and Vesna earns $17 more than Dawn. How many dollars does Chris earn if their combined wages are $163?

Answers

Call Dawn's wage x, we will have Vesna's wage = x + 17 and Chris' wage = 4x(x + 17). So we have the equation:
$x + (x + 17) + 4 * (x + 17) = 163 \n 2x + 17 + 4x + 68 = 163 \n 6x = 78 \n x = 13$
Therefore, Chris's wage:
$4 * (13 + 17) = 120$

How can I graph y=1000(1+.0925/12)^m

________________________________

This is the graph of how much money you have in the bank
after 'm' months, if you deposit $1,000 in your account and
the bank is paying you 9.25% per year compounded monthly.

(That also explains why they used 'm' for the variable and not 'x'.)

Here's how you can graph it:

-- Pick a number for 'm'. (Use a small one.)
-- Calculate the value of 'y'.
-- Write down both of them.

-- Do it again.

-- Do it again.

-- Do it again.

-- Do it a few more times.

Mark all the points you have calculated on the graph.
Five or six points should be enough to show you
what the graph is going to look like.
It's NOT a straight line.

$y = 1000(1 + (0.0925)/(12))^(x)$
$y = 1000(1 + (37)/(400))^(x)$
$y = 1000(1(37)/(400))^(x)$

The vertical height v, in feet, of a snowboarder jumping off of an overhang can be modeled by the function h(t)=15-10t-16t^2, where 15 is the initial height (in feet) of the overhang, -10 is the initial vertical velocity (in feet per second), and t is the time (in seconds). How long does it take the snowboarder to land after jumping off the overhang?"
