Answer:

Answer is D. Mean decreases and median stays the same

Step-by-step explanation:

First put the amounts in this format

$31, $39, $50, $50, $70, $82

Median (middle of all numbers) is 50

Mean (add all numbers then divide by how many amounts there) is 53.6

Now incorporate the 7th week

$23, $31, $39, $50, $50, $70, $82

Median is still 50

Mean is now 49.28

Area of circle is 314 inches^2

Circumference of circle is 62.8 inches

Step-by-step explanation:

We need to find area and circumference of the circle whose diameter is 20 inches.

Area of circle

The formula used to find area of circle is:

$Area=\pi r^2$

value of π = 3.14

we know radius = diameter/2

So, radius = 20/2 = 2

Putting value of π and radius we get Area:

$Area=\pi r^2\\Area= 3.14*(10)^2\\Area=3.14*100\\Area=314\,\,inches^2$

So, Area of circle is 314 inches^2

Circumference of Circle

The formula used to find circumference of circle is:

$Circumference=\pi d$

value of π = 3.14

diameter= 20

Putting value of π and diameter we get Circumference:

$Circumference=\pi d\\Circumference=3.14*20\\Circumference=62.8\,\,inches$

So, circumference of circle is 62.8 inches

what is the equation of a vertical line passing through the point (3, −5)? a. y=-5 b. x=-5 c. y=3 d. x=3

san4es73 [151]

VUX = vertical line, undefined slope, represented by x = a number.
so look at ur points (3,-5)....and a vertical line is represented by x = a number...so in ur points, the x value is 3, therefore, ur equation is :
x = 3......x will always be 3 no matter what y is.
