Answer:
The probability is 0.9938
Step-by-step explanation:
In this question, we are asked to calculate the probability that the mean blood pressure readings of a group of people is less than a certain reading.
To calculate this, we use the z score.
Mathematically;
z = (mean - value)/(standard deviation/√N)
From the question, we can identify that the mean is 125, the value is 123 , the standard deviation is 9.6 and N ( total population is 144)
Let’s plug these values;
z = (125-123)/(9.6/√144) = 2.5
Now we proceed to calculate the probability with a s score less than 2.5 using statistical tables
P(z<2.5) = 0.9938
Step-by-step explanation:
l = length
w = width
l/w = 5/2
l = 5w/2
l×w = 1000ft²
(5w/2)×w = 1000
5w²/2 = 1000
5w² = 2000
w² = 400
w = 20ft
l = 5w/2 = 5×20/2 = 5×10 = 50ft
the length is 50ft.
the width is 20ft.
