Hello, I Am BrotherEye

Answer: Here is an Example On How To Solve Your Problem.

Step-by-step explanation:

Explanation:

The minimum is the lowest number in the data set.

Since it is listed from smallest to largest, we know that the minimum is

The median is the middle number. Cancel out

numbers from each side and we are left with the median:

Therefore, the median is

The first quartile (Q1) is the median of the lower half of data which lies at 25% of the data.

Let's look at the lower half of numbers:

The number in the middle is

, so that is the first quartile.

The third quartile (Q3) is the median of the upper half of data which lies at 75% of the data.

Let's look at the upper half of numbers:

The number in the middle is

, so that is the third quartile.

The maximum is the highest number in the data set; it is

So here's the five-number summary:

Minimum: 29

First quartile: 33

Median: 37

Third quartile: 40

Maximum: 41

Pranav paints a wall of area 53m^2 one litre of paint covers an area of 4.5m^2 paint is sold in 2.5 litre tins, each costing $24

Alexus [3.1K]

Answer:

The cost of the paint will be $123.75.

Step-by-step explanation:

Since Pranav paints a wall of area 53m ^ 2, and one liter of paint covers an area of 4.5m ^ 2, and paint is sold in 2.5 liter tins, each costing $ 24.75, if Pranav buys the least number of tins to paint this wall, to determine the cost of the paint, the following calculation must be performed:

(53 / 4.5) = liters of paint needed

11.77 = liters of paint needed

11.77 / 2.5 = tins of paint needed

4.71 = tins of paint needed (rounds to 5)

5 x 24.75 = Total cost

123.75 = Total cost

The cost of the paint will be $123.75.

Area between two shapes. IXL geometry help pls !

-Dominant- [34]

Since we know the Circumference of the inner circle, we can divide by (pi symbol) to get the diameter of the inner circle.

87.92/3.14=28

With knowledge of 28 being the diameter, we can also solve for the radius, which is 14.

The area of the inner circle is (pi)14^2

The inner circle’s are is 615.44 unit^2

The outer circle’s radius is 14+7 or 21

(pi)21^2= 1,384.74

We subtract the inner circle’s area from the outer circle’s area.

1,384.74-615.44= 769.3

769.3 square kilometers
