Pretty sure it’s d, sorry if i’m wrong
In order to calculate the z-score of a normal distribution, you need to apply the formula:
z = (o - m) / s
where:
o = observed value
m = mean
s = standard deviation
In your case:
z = (259 - 239) / 25 = 0.8
The answer is, indeed, z = 0.8
Answer:
(5,4) & (8,-10)
Step-by-step explanation:
First step:
You can use any number you want for b (I used 4)
Make x=0
Make y=0
Subtract 4 from both sides
Divide both sides by 
Second step:
In order to make a line perpendicular to another the slope of the second line will be the negative inverse of the first line. So 
will be 
for the second line.
Then you just need to repeat the process in first step to get the intercepts. (Again I used a random number like -10 for b)
Answer:
The least value plotted on the line plot is 18.0
The greatest value plotted on the line plot is 22.0
The height of inches occurs the most often is 19.5 with 3 times
Step-by-step explanation:
A line plot is a graph that shows frequency (the number of times the data value occur) of data along a number line.
The line plot has dots plotted on it over each value of the number line.
