When the population mean and standard deviation are known, you use the standard normal distribution

<h3>How to determine the distribution?</h3>

There are several probability distributions; these include

  • Normal distribution
  • Poisson distribution
  • Chi square distribution
  • Binomial distribution
  • Etc

Of all these distribution, only the standard normal distribution can be used when the population mean and standard deviation are known,

Note that it is also referred to as the z-distribution

What percent of 17 is 51?
Taya2010 [7]

Answer:

33%

Step-by-step explanation:

h steps:

Step 1: We make the assumption that 51 is 100% since it is our output value.

Step 2: We next represent the value we seek with $x$.

Step 3: From step 1, it follows that $100\%=51$.

Step 4: In the same vein, $x\%=17$.

Step 5: This gives us a pair of simple equations:

$100\%=51(1)$.

$x\%=17(2)$.

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

$\frac{100\%}{x\%}=\frac{51}{17}$

Step 7: Taking the inverse (or reciprocal) of both sides yields

$\frac{x\%}{100\%}=\frac{17}{51}$

$\Rightarrow x=33.33\%$

Therefore, $17$ is $33.33\%$ of $51$.

How to find MP when discount percent and SP are given​
nadezda [96]

Given:

Consider the discount percent and SP are given​.

To find:

The MP.

Solution:

Let x% be the discount percent Then

SP=MP-x\%\text{ of }MP

SP=MP-\dfrac{x}{100}MP

SP=\left(1-\dfrac{x}{100}\right)MP

SP=\left(\dfrac{100-x}{100}\right)MP

Multiply both sides by 100.

100SP=(100-x)MP

Divide both sides by (100-x).

\dfrac{100}{100-x}SP=MP

Therefore, the formula for MP is MP=\dfrac{100}{100-x}SP, where x is the discount percentage.
