Step-by-step explanation:
the slope is the ratio "y coordinate difference / x coordinate difference".
so,
(2 - 6) / (x - 2) = 4/7
-4 / (x - 2) = 4/7
-1 / (x - 2) = 1/7
-1 / (x - 2) = 1 / -(x - 2) = 1/7
-(x - 2) = 7
-x + 2 = 7
-x = 5
x = -5
so, the point is (-5, 2)
A, 2.
Step-by-step explanation:
The formula is (y2-y1)/(x2-x1) so just follow that.
Using the normal distribution, it is found that she scores less than 128 in 28.1% of her games.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean
and standard deviation
is given by:

- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
In this problem, the mean and the standard deviation are given, respectively, by
.
The proportion of games in which she scores less than 128 is the <u>p-value of Z when X = 128</u>, hence:


Z = -0.58
Z = -0.58 has a p-value of 0.281.
She scores less than 128 in 28.1% of her games.
