Tristan records the number of customers who visit the store each hour on a Saturday. His data representing the first seven hours are 15, 23, 12, 28, 20, 18, and 23. How many customers visited the store during the eighth hour if the median number of customers per hour did not change?16
19
20
23

Answers

The number of Customers that visited the store during the eight hour if the median number of customers didn't change is; C: 20

What is the Median?

We are given the data representing the first seven hours as; 12, 15, 18, 20, 23, 23, 28. Here; n=7

Thus;

Median = (n + 1)/2 = (7 + 1)/2

Median = 4th term

Thus, the median is 20.

When one data is added, n = 8. Thus;

Median will be the average of the 4th and 5th term. Since the median does not change, it means that the median number of customers per hour is still 20.

a Potter uses 3/5 of a pound of clay to make a bowl. how many bowls could the Potter make with 10 pounds of clay?

Answers

Divide 10 pounds by 3/5 to find the number of bowls he can make. $(10)/( (3)/(5) ) = (50)/(3)$ . but since he can't make a partial bowl, we round down, meaning that the potter makes 16 bowls.

The solution is 9/49

The value of the equation is A = 9/49

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the number be n = 3/7

The equation A = n²

Substituting the value for n in the equation , we get

A = ( 3/7 )²

On simplifying the equation , we get

A = ( 3 )² / ( 7 )²

The value of A = 9/49

Therefore , the value of A is 9/49

Hence , the equation is A = 9/49
