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
Answer:
Step-by-step explanation:
Subtract 5 from both sides.
Simplify.
Multiply both sides by 4.
Simplify.
Divide both sides by 3.
Simplify.
Answer:
Step-by-step explanation:
A = 2π +πrl
A - 2π = πrI subtract by 2π
(A- 2π)/(πr) = I divide by πr to isolate I
Answer:
16 inches
Step-by-step explanation:
If each inch is 1/2 a foot, that means you would have to multiply 8 (the actual width) by 2 (representing halves) to get 16.
