Answer:

The median of the data is 4.

Step-by-step explanation:

The median means the middle number of a given number.

To decide which one is the median, arrange in ascending or descending order. But sometimes, you may find two(2) number in the middle, but it's easy, just add them together and divide by 2.

So, Determine the median of the data. 2, 3, 3, 4, 5, 7, 9

It is already arranged, count 3 times forward and 3 backward and the one left is your answer.

2,3,3,4,5,7,9

Our answer is 4.

Hope this helps!

The median is 4 because 2 x’s out 9, 3 x’s out 7, 3 x’s out 5, and 4 is the only remaining number.

The sales tax in your city is 8.8%, and an item costs $63 before tax.

Maru [420]

Answer: 5.54

Nolan and his children went into a grocery store and he bought $8 worth of apples

goldfiish [28.3K]

Nolan and his children bought fruits (Apples and bananas) worth $8.

Cost of each apple and bananas are $2 and $0.40 respectively.

Let the number of bananas he bought = y

And the number of apples = x

Therefore, cost of the apples =$2x

And the cost of bananas = $0.40y

Total cost of 'x' apples and 'y' bananas = $(2x + 0.40y)

Equation representing the total cost of fruits will be,

(2x + 0.40y) = 8

10(2x + 0.40y) = 10(8)

20x + 4y = 80

5x + y = 20 --------(1)

If he bought 5 times as many bananas as apples,

y = 5x ------(2)

Substitute the value of y from equation (2) to equation (1),

5x + 5x = 20

10x = 20

x = 2

Substitute the value of 'x' in equation (2)

y = 5(2)

y = 10

Therefore, Nolan bought 2 apples and 10 bananas.

A six-foot-tall person walks from the base of a broadcasting tower directly toward the tip of the shadow cast by the tower. When

zhuklara [117]

Answer:

270 feet

Step-by-step explanation:

For clarity, the image below represents the problem. Let's call h the height of the tower. Notice that it forms 2 triangles that are similar to side-angle-side. So, we can calculate the higher of the tower by similar triangles:

higher1/base1 = higher2/base2

h/135 = 6/3

h/135 = 2

h = 270 ft
