Plug in x and y
1 / [2(4)3+3.4(2)]
1 / 24+6.8
1 / 30.8
Let u be the set of all words containing 7 letters(26 letters to the power 7)
The answer is 2.
3/2a - ab + 1
3/2(5/6) - 5/6(3/10) + 1
5/4 - 1/4 + 1
4/4 + 1
1 + 1 = 2
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
