Answer:
y =
Step-by-step explanation:
Let the equation of the line is,
y = mx + b
Here m = slope of the line
b = y-intercept
Slope of a line passing through two points and
is,
m =
From the graph attached,
Since, the given line passes through (0, -1) and (3, 4),
Slope 'm' =
m =
y - intercept 'b' = -1
Therefore, equation of the line will be,
y =
Answer:
Step-by-step explanation:
Given that the number of orders received daily by an online vendor of used CDs (say X) is normally distributed with mean 270 and standard deviation 16.
X is N(270, 16)
To find percentage of days will the company have to hire extra help or pay overtime, we can find probability using std normal table
X>302 means
P(Z>2) = 0.25
Thus 25% of days will the company have to hire extra help or pay overtime
