If a coin is tossed twice what is the probability of getting two heads

Mathematics

25% because the first FLIP, it was a fifty-fifty chance. FLIP again and the chances are divided by two since you can only get 2 things, either heads or tails.

hailey wanted to fill her circular pool with water for the summer how much water does she need to fill her pool that is 6 feet d
Setler [38]
The circle area times the depth gives the volume of a cylinder.

Radius is half diameter = 25 ft

Area circle = π(25)²
= 625π

multiply by depth to find volume.
= 625π(6)
= 11,781

I'd say C. is the closest. I don't round numbers until the end so if you round π to 3.14 it's probably the same

Do side lengths 8,7 and 15 create a triangle ?
dexar [7]

Answer:

Yes

Step-by-step explanation:

To make a triangle the 2 smaller sides must join together to become greater than or equal to the biggest side.

8+7=15

<em>Therefore,</em>

<em>side lengths 8, 7, and 15 do create a triangle.</em>

<em />

<em>Hope this helps </em>

Find the value of x.
Slav-nsk [51]

Answer:

  x = 53

Step-by-step explanation:

The sum of the angle measures in a triangle is 180°:

  91° + 36° + x° = 180°

  x° = 180° -127° = 53°

  x = 53

Which of the following functions I which of the following functions are one to one? Select all that apply there are 3 answers
ivann1987 [24]

Answer:

The function f(x)=\frac{x-1}{3x+3} is one-to-one function ⇒ 1st

The function f(x)=\sqrt{5x+9} is one-to-one function ⇒ 2nd

The function f(x)=\frac{1}{2}x^{3} is one-to-one function ⇒ 4th

Step-by-step explanation:

* Lets explain how to solve this problem

- One to one function is the function that has no reputation in the value

 of the y-coordinates for every corresponding x-coordinates

- That means when you draw a horizontal line at any value of y, then

  the horizontal line intersects the graph of the function at one point

  only

- So to solve the problem look to the attached figures

# The red graph of the function f(x)=\frac{x-1}{3x+3} ⇒1st graph

- In this graph if we draw a horizontal line at any value of y it will

 intersect the graph at only one point

- Take care there is a horizontal asymptote at y= 1/3, that means

  there is no value of x at y = 1/3

∴ The function f(x)=\frac{x-1}{3x+3} is one-to-one function

# The blue graph of the function f(x)=\sqrt{5x+9} ⇒2nd graph

- In this graph if we draw a horizontal line at any value of y it will

 intersect the graph at only one point

∴ The function f(x)=\sqrt{5x+9} is one-to-one function

# The green graph of the function f(x)=\frac{1}{2}x^{3} ⇒3rd graph

- In this graph if we draw a horizontal line at any value of y it will

 intersect the graph at only one point

∴ The function f(x)=\frac{1}{2}x^{3} is one-to-one function

# The purple graph of the function f(x)=\frac{7}{4x^{2}} ⇒5th graph

- In this graph if we draw a horizontal line at any value of y it will

 intersect the graph at more than one point

∴ The function f(x)=\frac{7}{4x^{2}} is not one-to-one function

# The black graph of the function f(x)=3x^{4}+7x^{3} ⇒4th graph

- In this graph if we draw a horizontal line at any value of y it will

 intersect the graph at more than one point

∴ The function f(x)=3x^{4}+7x^{3} is not one-to-one function

* The answers are 1st , 2nd and 4th functions
