So first find the amount of change from the original to now.

37.90-22.74=15.16

Now find what percent of that is out of 37.90.

So do:

15.16/37.90

= 0.4

So its was a 40% discount.

What is the relationship between partitions and number series
vovangra [49]
A sum of positive natural numbers adding up to n is called a partition of n. For instance, 1+2+4 is a partition of 7. As none of the summands 1, 2, 4 are equal, this is called a partition into unequal parts. Does this help? Because this is all I know :(

A random number from 1 to 5 is selected
shutvik [7]

Answer:

Relative frequency of selecting a 2 = 8/50 = 0.16

Relative frequency of selecting a 3 = 14/50 = 0.28

Step-by-step explanation:

When we have a given experiment with given outcomes (such that each time that we perform the experiment, one outcome happens) the relative frequency of a given outcome is the quotient between the number of times that that outcome happened, and the total number of times that the experiment was performed.

Here the experiment is selecting a random number between 1 and 5, and it is performed 50 times.

Out of these 50 times, the outcome "2" appears 8 times.

Then the relative frequency of selecting the number 2 is:

f(2) = 8/50 = 0.16

And of these 50 experiments, the outcome "3" appears 14 times.

Then the relative frequency of selecting the number 3 is:

f(3) = 14/50  = 0.28
