354 / 4 = 88.5
so2 numbers below that and 2 numbers above that:
87 + 88 + 89 +90 =
2nd number is 88
Answer:
The correlation between exam score and amount of time spent on the exam is an example of a <u>negative correlation</u>.
Step-by-step explanation:
Consider the provided statement.
College professor reports that students who finish exams early tend to get better grades than students who hold on to exams until the last possible moment.
That means the student who finish the exam early will get the highest marks. One who finish after the first student will get second highest mark and the one who finish in the end will get the least marks.
Now consider time as first variable and marks as second variable.
That means as the first variable increase the second variable decreases.
According to the definition of Negative correlation: It is a relationship between two variables in which one variable increases as the other decreases, and vice versa.
Hence, the correct answer is negative correlation.
Answer:
l=5.12 & w=2.62
Step by step explanation:
A=l×w
13.42=lw
w=13.42/l

Since you have found the value of the length you can find the value.of the width.

You basically have to find the slope, to find the average rate of change, because finding the slope and finding the average rate of change is basically the same thing.
Here's the formula :

So here, all you'd have to do is simply pick two points, and insert them into this formula. Say you take the points (-2, -2) and (0,-3). You would start from the y-intercept of the second point, and insert them all into the formula.
which would turn into
. And so since you want a good, stable number, and not just a fraction, you would divide -1 and 2, and the average rate of change would be
-0.50.
AVERAGE RATE OF CHANGE :
-0.50
