The ordered pairs below represent a linear relation between x and y.
2 answers:
Answer: b. The slope of the line represented by this table is 3 and the y-intercept is 6.
Step-by-step explanation:
Given : The ordered pairs below represent a linear relation between x and y.
(-3,-3), (-2,0), (-1,3), (0,6), (1,9), (2,12)
The slope of line is given by :
Now, slope of the given line by using points (-3,-3) and (-2,0).
Hence, the slope of line is 3.
We know that the y intercept has x coordinat zero.
From the given points we can see that in point (0,6), x coordinate is 0.
Therefore, the y intercept of the line is 6.

7.64% probability that they spend less than $160 on back-to-college electronics
Step-by-step explanation:
Problems of normally distributed samples can be solved using the z-score formula.
In a set with mean and standard deviation
, the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
Probability that they spend less than $160 on back-to-college electronics
This is the pvalue of Z when X = 160. So
has a pvalue of 0.0763
7.64% probability that they spend less than $160 on back-to-college electronics
