Answer: 16

Step-by-step explanation:

The median is the middle number of a set of data (if there are an odd number of data values) or the average of the two middle numbers (if there are an even number of data values).

A box-whisker plot gives us information of the shape, variability, and median of a data set.

From the given box-whisker plot a vertical line goes through the box at 16 i.e. the median.

Hence, the median of the data set = 16.

1. What is the solution to the system below? x+y=5 1x- y=3

Alika [10]

Answer:

(4,1)

Step-by-step explanation:

x+y=5

x- y=3

Add the equations together to eliminate y

x+y=5

x- y=3

--------------------

2x = 8

Divide each side by 2

2x/2 = 8/2

x = 4

Now we can find y

x+y = 5

4+y = 5

Subtract 4 from each side

4+y-4 = 5-4

y =1

The perimeter of a rectangle is 100 yd. if its width is four times its length, what is the area?

7nadin3 [17]

Length = l

Width = w

Perimeter = p = 100

Perimeter of rectangle = 2(l+w)

100 = 2 (4w + w)

100 = 2(5w)

100 = 10w

100/10 = w

10 = w

w = 10

Area of rectangle = length * width

a = l*w

a = 4w*w

a = 4w^2............(1)

Put the value of w in (1)

a = 4(10)^2

a= 4(100)

a = 400 yd^2

Identify the Asymptotes for the graphs below help pls!

scoray [572]

Asymptotes are lines that continues to approach a given curve but never actually meets it! For the second figure it is the Y axis since the curves slowly appear to approach the Y axis! Not sure about the first figure(probably the X axis)!

A metalworker has a metal alloy that is 15% copper and another alloy that is 75% copper. How many kilograms of each alloy shou

lisov135 [29]

48 kilograms of 15 % copper is combined with 72 kilograms of 75 % copper to create 120 kg of a 51% copper alloy

Solution:

Let "x" be the kilograms of 15 % copper

Then, (120 - x) be the kilograms of 75 % copper

Then, according to question,

"x" kilograms of 15 % copper is combined with (120 - x) kilograms of 75 % copper to create 120 kg of a 51% copper alloy

Thus we frame a equation as:

15 % of x + 75 % of (120 - x) = 51 % of 120

Solve the equation for "x"

$15 \% \times x + 75 \% \times (120-x) = 51 \% \times 120\\\\\frac{15}{100} \times x + \frac{75}{100} \times (120-x) = \frac{51}{100} \times 120\\\\0.15x + 0.75(120-x) = 0.51 \times 120\\\\0.15x + 90 - 0.75x = 61.2\\\\0.6x = 90 - 61.2\\\\0.6x = 28.8\\\\Divide\ both\ sides\ by\ 0.6\\\\x = 48$

Thus 48 kilograms of 15 % copper used

Then, (120 - x) = (120 - 48) = 72

Thus, 72 kilograms of 75 % copper is used
