Answer:
B
Step-by-step explanation:
Since r and s are parallel lines, then
The angle adjacent to 1 is corresponding to 158 and are congruent, thus
adjacent angle to 1 = 158°
1 and 158° are adjacent and supplementary, so
∠ 1 + 158° = 180° ( subtract 158° from both sides )
∠ 1 = 22° → B
Answer: D) The linear model shows a strong fit to the data
The actual strength of the relationship is unknown unless we have the actual values of each data point (so we can compute the correlation coefficient r), but the residuals are randomly scattered about both above and below the horizontal axis. This means we have a fairly good linear fit. If all of the points were above the line, or all below the line, or all residuals fit a certain pattern (eg: parabola), then it wouldn't be a good linear fit.
Answer:
The points corresponding to P=(3,4) and Q=(6,7), so the answer is D.
Step-by-step explanation:
Ok, in mathematics, given two sets X and Y, the collection of all the ordered pairs (X, Y), formed with a first element in X and a second element in Y, is called the Cartesian product of X and Y. The Cartesian product of sets allows define relationships and functions. In this case, it is a function that contains two points, denoted P and Q. Given, the ordered pair of each, first read the one corresponding to the X axis and then to the Y axis.
For P: you read X and you see that it is on 3 (between 2 and 4), and then the Y axis is on 4 (between 3 and 5).
For Q: you read X and you see that it is on 6 (between 5 and 7) and then the Y axis is on 7 (between 6 and 8)
There are two cases:
1.
2.
So the minimum temperature is -6, and the maximum is 18.
