There are 625 different 4-digit codes only made with odd numbers.

<h3></h3><h3>How many different combinations can you make?</h3>

To find the total number of combinations, we need to find the number of options for each one of the digits.

There are 4 digits, such that each digit can only be an odd number.

  • For the first digit, there are 5 options {1, 3, 5, 7, 9}
  • For the second digit, there are 5 options {1, 3, 5, 7, 9}
  • For the third digit, there are 5 options {1, 3, 5, 7, 9}
  • For the fourth digit, there are 5 options {1, 3, 5, 7, 9}

The total number of different combinations is given by the product between the numbers of options, so we have:

C = 5*5*5*5 = 625.

There are 625 different 4-digit codes only made with odd numbers.

The answer is c because when it's an inequality, x=4 that means that you need to put it in a numberline and since the numbers to your left will always be less than 4 the shaded part is on the right.

Jack wants to share his candy with friends. Right now he has 4 1/3 pieces of chocolate. How many friends can he give 1/2 a candy
cricket20 [7]

Answer:

8 Friends

Step-by-step explanation:

First convert 4 1/3 to a mixed fraction

4 1/3 --> 13/3

Then divide by 1/2 to find how many friends per 1/2 candy bar with 13/3 candy bars

(13/3)/(1/2)

=(13*2)/(3*1)

=26/3

8.66667

Since you can't have 0.66667 of a person you get 8 friends to give candy to

When relationship between two or more variables are to be established such that the measure of the effect of one variable (independent variable) on the other variable (dependent variable) is evaluated , this is called correlation study or analysis. In the scenario above, the relationship between productivity or revenue and employee shift is correlated, that is a relationship was established between the revenue made and the shift days of a particular employee, which yielded a positive association between the two variables.
