Answer:

$22,320

Step-by-step explanation:

1. Understanding

Mean is the average of a given set

2. Solving

We have to find the average of all of these numbers.

How do I find the average?

I add all of the numbers and divide by the number of numbers I added. Example:

(x + x + x + x)/4 or,

(x+x)/2 and examples in numbers:

(3+4)/2 or,

(9+4+8+5+7)/5

See what I mean? Dividing by the number of numbers I have.

Ok, now we know that, we can solve!

Here is the equation for this problem:

(24,600+19,000+33,000+15,000+20,000)/5 (We have 5 numbers)

We have to do Parentheses First

(24,600+19,000+33,000+15,000+20,000)/5 --> 111,600/5

111,600/5 = 22,320

22,320 is the average number of all of the numbers, which is the mean

a volley ball player servers the ball. The ball follows a path given by the equation y=-0.01x^2+0.5x+3 where x and y are measure
dolphi86 [110]

Answer:

(a)

Distance from player should be 13.82 feet or 36.2 feet

(b)

The ball will go over the net

Step-by-step explanation:

we are given

The ball follows a path given by the equation

y=-0.01x^2+0.5x+3

where

x and y are measured in feet and the origin is on the court directly below where the player hits the ball

(a)

net height is 8 ft

so, we can set y=8

and then we can solve for x

8=-0.01x^2+0.5x+3

8\cdot \:100=-0.01x^2\cdot \:100+0.5x\cdot \:100+3\cdot \:100

800=-x^2+50x+300

-x^2+50x-500=0

x^2-50x+500=0

we can use quadratic formula

x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}

x=\frac{-50\pm \sqrt{50^2-4\left(-1\right)\left(-500\right)}}{2\left(-1\right)}

x=5\left(5-\sqrt{5}\right),\:x=5\left(5+\sqrt{5}\right)

x=13.82,x=36.2

So, distance from player should be 13.82 feet or 36.2 feet

(b)

we can plug x=30 and check whether y=8 ft

y=-0.01(30)^2+0.5(30)+3

y=9ft

we know that

height of net is 8 ft

so, the ball will go over the net

Help!!! I don’t understand how to do this
Olegator [25]

Answer:

85 degrees

Step-by-step explanation:

the sum of supplementary angles=180

155+ angle in the triangle=180

angle=180-155

angle=25 degrees

the sum of angles of triangle=180

25+60+x=180

85+x(inside triangle)=180

x=180-85

x=95

angle with (?):

the sum of supplementary angles=180

95+(?)=180

(?)=180-95

(?)=85 (An exterior angle of a triangle is equal to the sum of the opposite interior angles)
