Given
See attachment for grid
Required
Which point is on Veronica's path
On the attached grid, I plotted each of the coordinate pair (i.e the given options, A to D) on the grid.
By observation. we can see that:
A is on the vertical line (y intercept)
B is on the second quadrant
C is just few points to the left of the given path
D represents Verlonda's house
<em>Hence, the required coordinate pair is: (3.8)</em>

Answer:
4.05% probability that a randomly selected adult has an IQ greater than 123.4.
Step-by-step explanation:
Problems of normally distributed samples are 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 question, we have that:

Probability that a randomly selected adult has an IQ greater than 123.4.
This is 1 subtracted by the pvalue of Z when X = 123.4. So



has a pvalue of 0.9595
1 - 0.9595 = 0.0405
4.05% probability that a randomly selected adult has an IQ greater than 123.4.
Rectangle and parallelogram
It will have two pairs of parallel sides.
When two variables have an inverse relationship, the slope is negatively correlated.
