Answer: 0.7619
Step-by-step explanation:
Given : Mean :
Standard deviation :
Sample size :
We assume that the variable is normally distributed.
The value of z-score is given by :-
a) For x= 46.9 years
The p-value :
Hence, the probability that the average age of those doctors is less than 46.9 years =0.7619
Answer:
9%
Step-by-step explanation:
Calculation for What percentage is her salary
Using this formula
Dianes salary percentage=Car payments per year/Salary per year
Let plug in the formula
Dianes salary percentage=$2,880 per year/$32,000 per year
Dianes salary percentage=0.09*100
Dianes salary percentage=9%
Therefore the percentage of her salary is 9%
I’m just as confused as you are, what is the question even supposed to be? If they are asking what solution you would use that step in then I think it would be to find the area but I’m not sure
Answer:
see the explanation
Step-by-step explanation:
we know that
A linear function in slope intercept form is equal to
where
m is the slope or unit rate
b is the y-intercept
x is the independent variable or input value
f(x) is the dependent variable or output value
In this problem we have
where
m is the number of miles
f(m) is the cab company's fare in dollars
we have that
In this context
<em>Slope</em>
The slope or unit rate is equal to the cost per mile for the riders trip
The slope is $3 per mile
<em>Y-intercept</em>
The y-intercept is the cost of the riders trip when the number of miles is equal to zero, also is called the initial value.
The y-intercept is $5
51/40 is the simplest for because the only common factor of them both is 1
