Answer:

10/14 or about a 71% chance

Step-by-step explanation:

First you add up all of the players and you get 14. If, at random the coach picks a player, to find the chance that it is not a senior just add up all of the people that arent seniors. You then get a 10 out of 14 (about 71%) chance that the coach will pick somone that is not a senior. I hope this helps :)

The function f(x) = (x - 4)(x - 2) is shown.
agasfer [191]

Answer:

all real numbers greater than or equal to -1

Step-by-step explanation:

In order to solve this problem we need to know the vertex and the direction its pointing.

First we expand,

x^2-6x+8

To find the x value of the vertex we use this formula (-b/2a).

-(-6)/2(1) = 3

Now we plug 3 in the equation to get the y value,

(3)^2 - 6(3) + 8 = 9 - 18 + 8 = -1

The vertex is (3,-1)

We know the graph points up because x^2 is positive

The vertex is the lowest point, so we now know that -1 is the starting range and if the graph is pointing up, that means all values greater than -1.

This leads to our answer all real numbers greater than or equal to -1.

Answer:

(2,1) (7,1) (7,5) (2,5)

Step-by-step explanation:

Just line up the dots on the x axis and y axis

Vertexes are the points or "corners" of the shape, and in your case, that square.

I hope this helped :D

What is the square root of 5x^2 = 300
vesna_86 [32]

So, values of x are: x=2\sqrt{15},\,\,x=-2\sqrt{15}

Step-by-step explanation:

We need to find the square root of 5x^2 = 300

Writing in mathematical form:

5x^2=300

Divide both sides by 5

\frac{5x^2}{5}=\frac{300}{5}

x^2=60

Taking square root on both sides

\sqrt{x^2}=\sqrt{60}

x=\pm (\sqrt{2\times 2\times 3\times 5})

x=\pm (\sqrt{2^2 \times 3\times 5})

x=\pm (2\sqrt{3\times 5})

x=\pm (2\sqrt{15})

x=2\sqrt{15},\,\,x=-2\sqrt{15}

So, values of x are: x=2\sqrt{15},\,\,x=-2\sqrt{15}

A bicycle store costs ​$4200 per month to operate. The store pays an average of ​$75 per bike. The average selling price of each
Lelechka [254]

Store should sell about 31 bicycle for average price of $135 each bicycle.

Step-by-step explanation:

  • To find bike we need Algebra to solve the equation.
  • when x = 1 , Y = 135 *x
  • When x 2 , Y = 135 *2
  • Formula you could apply to go for break even y = 135*x
  • Bicycle store pays about $4200
  • Algebra used for every business and working to make easy task.
  • It takes about 31 bicycle a month to get into break even.
  • Every store needs break even to not incur lost.
  • Break even point is equilibrium between income and expenses.

If numerator is 2 less than the denominator of a rational number and when 1 is subtracted from numerator and denominator both, t
xenn [34]

Answer:

\frac{3}{5}

Step-by-step explanation:

  • Let the denominator be x
  • So, numerator = x - 2
  • According to the given condition: when 1 is subtracted from numerator and denominator both, the resulting new rational number in its simplest form is \frac{1}{2}

  • \implies \frac{x-2-1}{x-1}=\frac{1}{2}

  • \implies \frac{x-3}{x-1}=\frac{1}{2}

  • \implies 2(x-3)=x -1

  • \implies 2x-6=x -1

  • \implies 2x-x=6-1

  • \implies x=5

  • \implies x-2=-5-2= 3

  • Required \: rational\: number = \frac{3}{5}
