Answer:
a) 20%
b) 40%
c) Mean = 62.5 seconds; Variance = 52.083 seconds
Step-by-step explanation:
The time it takes a hematology cell counter to complete a test on a blood sample is continuously distributed over the period of 50 to 75 seconds with probability f(x) = 0.04.
a) The percentage of tests require more than 70 seconds is:

b)The percentage of tests that require less than one minute (60 seconds) is:

c) The mean and variance of a continuous distribution are determined by:

Mean = 62.5 seconds.
Variance = 52.083 seconds.
If you mean "what is the radius in feet of a circle that is 706.5 ft in diameter", then the answer is 353.25 ft.
Otherwise, I o no.
Answer: 3.19
Step-by-step explanation:
So to find the average I used a simple but pretty effective method
3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+8/26=3.1923
So the new average is 3.19
Answer:
Slope form of line y = 4x +41
Step-by-step explanation:
m= 4
The y-intercept of the line that passes through the given point (-9,5) is
5 = 4(-9) + b
b= 5 +36
b=41
The equation of the line that passes through the given point (-9,5) is
y =mx +b
y = 4x +41
