First, arrange the data from lowest to highest
19, 20, 21, 22, 23, 24, 25, 27, 29, 30, 33

Next, find the media or the middle data.
The median is 24.
19, 20, 21, 22, 23, 24 (median), 25, 27, 29, 30, 33

Lastly, look at the data below the median and find the middle of those data. If it's between two numbers, choose the lower number. That's the first quartile.
The first quartile is 21.
19, 20, 21(Q1), 22, 23, 24 (median), 25, 27, 29, 30, 33

we know that

The Triangle Inequality Theorem, states that the sum of the lengths of any two sides of the triangle is greater than the length of the third side

$AB+AC > BC\\AB+BC > AC\\AC+BC > AB$

we have

$AB=12\ units\\AC=15\ units\\ BC=x\ units$

substitute the values

$12+15 > x$ -----> $x < 27\ units$

$12+x > 15$ -----> $x > 3\ units$

$15+x > 12$ -----> $x > -3\ units$

$3\ units < x < 27\ units$

therefore

the answer is

The value of x must be greater than $3$

Assume that blood pressure readings are normally distributed with a mean of 123 and a standard deviation of 9.6. If 144 people a

Vanyuwa [196]

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
