What is inequality?Inequality is defined as the relation which makes a non-equal comparison between two given functions.
An inequality is a mathematical statement which compares two values or expressions using a relational operator, such as less than (<), greater than (>), less than or equal to (≤), greater than or equal to (≥), or not equal to (≠). Inequalities are used to show relationships between quantities or to express constraints or conditions.

a data set has a mean 25 and standard deviation 5 find the z score of 39
Answers
Answer:
[tex]\boxed {\boxed {\sf z=2.8}}[/tex]
Step-by-step explanation:
The z-score helps describe a value's relationship to the mean. It tells us how many standard deviations a value is from the mean. The formula is:
[tex]z= \frac{x- \bar x}{s}[/tex]
where x is the value, x-bar is the mean, and s is the standard deviation.
We know the data set has a mean of 25 and a standard deviation of 5. The value we are finding the z score for is 39.
x= 39 x-bar= 25 s=5Substitute the values into the formula.
[tex]z= \frac{ 39-25}{5}[/tex]
Solve the numerator.
[tex]z= \frac{ 14}{5}[/tex]
[tex]z=2.8[/tex]
The z-score for 39 is 2.8. This means a value of 39 is 2.8 standard deviations greater than the mean.

Below is the normal distribution curve for height (inches) of NBA basketball players.
What is the standard deviation?
Answers
Answer: standard deviation = 8
This is because mu = 75 is the mean, which is at the very exact center of this distribution. One space to the right is 83, which is 83-75 = 8 units away from the center. This distance is exactly one standard deviation. We can say "83 is one standard deviation larger than 75".
Or you could note the distance from 67 to 75 is also 8, because 75-67 = 8. Each tickmark represents stepping one standard deviation in distance.

Step-by-step explanation:
We are given a 45°-45°-90° triangle with hypotenuse measuring 18 cm.
Let us assume the following labeling of the diagram, as attached in the answer area.
The two angles here are equal to 45° so two sides of the triangle opposite to the equal angles will also be equal to each other i.e. it is an isosceles triangle.
i.e. The sides XY and YZ will be equal.
Let XY = YZ = x cm
It is known that in a right angled triangle, pythagorean theorem holds well.
