A median is the middle number of a data set.
To find it put the numbers in order.
78, 69, 69, 96, 99
Then find the middle number
78, 69, *69,* 96, 99

The median is 69

A mode is the number that appears the most in a set of numbers.
78, *69, 69,* 96, 99

The mode is 69

To find the mean or average of a set of numbers, add all the numbers together then divide by the number of numbers there are.
99+69+96+69+78 = 411
411/5 = 82.2

The mean is 82.2

Temka [501]

Answer:

25

Step-by-step explanation:

We can use the Pythagorean theorem to fin x

a^2 + b^2 = c^2  where a and b are the legs and c is the hypotenuse

7^2 + 24^2 = x^2

49+ 576 = x^2

625 = x^2

Take the square root of each side

sqrt( 625) = sqrt(x^2)

25 = x

IgorC [24]

Answer:

The cost store owner pay for the pair of jeans is <u>$42</u>.

Step-by-step explanation:

Given:

A store owner uses a selling price of 125% of the cost of an item.

If a pair of jeans has a sales price of $52.50.

Now, to find the cost price of the store owner pay for the pair of jeans.

Let the cost price of jeans be x.

Sell price of jeans = \$52.50.

Now, to get the cost price of store owner pay for the pair of jeans:

<em>As given the</em><em> </em><em>store owner uses a selling price of 125% of the cost of an item.</em>

According to question:

125\%\ of\ x=52.50

\frac{125}{100} \times x=52.50

1.25x=52.50

<em>Dividing both sides by 1.25 we get:</em>

x=42.

<em>The cost price of jeans = $42.</em>

Therefore, the cost store owner pay for the pair of jeans is $42.
