A fair coin is flipped twice.
What is the probability that the coin will land heads up both times?

Answer:

The second way of approximating a square root is to use a calculator. Most calculators have a radical sign on them. To find the square root of a number, we enter the radical sign.

Answer:

The equation of the circle is (x+3)^2 + (y-4)^2 = 16.

Step-by-step explanation:

The equation of a circle can be calculated if the center and the radius are known. The equation of a circle is given by  (x-h)² + (y-k)² = r²

Where  (h, k) = center coordinates  and r = radius.

Step-by-step explanation:

U would be {0,1,2,3,4,5,6,7,8,9}

A would be {0,1,2,3,4,5}

and B would be {5,6,7,8,9}

The union would be {0,1,2,3,4,5,6,7,8,9}

And their intersection {5}

The elements of sets are A = { 1,2,3,4,5 }, B = { 5,6,7,8,9,10 },                          A ∪ B = { 1,2,3,4,5,6,7,8,9,10} and A ∩ B = { 5 }.

"A set is a collection of objects. The objects are called the elements of the set. If a set has finitely many elements, it is a finite set, otherwise it is an infinite set".

For the given situaton,

Union set U = { 1,2,3,4,5,6,7,8,9,10 }

Set A = { 1,2,3,4,5 }

Set B = { 5,6,7,8,9,10 }

Union of sets A and B is [tex]A[/tex] ∪ [tex]B[/tex] = { 1,2,3,4,5,6,7,8,9,10}

Intersection of sets A and B is [tex]A[/tex] ∩ [tex]B[/tex] = { 5 }

The venn diagram below shows the sets U, A and B.

Hence we can conclude that the elements of sets A, B, A ∪ B, A ∩ B are listed.

[tex]300 \geqslant 22.5x + 200[/tex]

Step-by-step explanation:

300 is less than or equal to 22.5x + 200

the budget is 300 so you can't go past that number. the appropriate inequality sign for this would be less than or equal to the following equation: $22.5 x (where x= number of hours) + the fixed fee of $200

Answer: 2,916 inches³

Step-by-step explanation:

The volume of a box is:

= Length * Width * Height

But all of these have to have the same units for it to work. This means that the height of the box will have to be converted to inches :

1 ft is 12 inches so:

= 1¹/₂ * 12

= 3/2 * 12

= 18 inches

Volume is therefore:

= 18 * 9 * 18

= 2,916 inches³

Step-by-step explanation:

Answer:

The system of equations is:

x + y = 42

4x + 2y = 120

And there are 24 chickens.

Step-by-step explanation:

We know that the total number of cows (x) plus the total number of chickens (y) is 42, because Farmer Brown has 42 animals.

We also know that cows (x) have 4 legs and so 4 times the number of cows is the number of cow legs. And chickens (y) have 2 legs, so the number of chickens times two represents the total chicken legs. The sum of 4x + 2y is 120 because there are 120 legs in total.

To solve the system of equations, first solve each equation for y.

In the first equation:

x + y = 42

Subtract x from both sides to isolate y.

y = 42 - x

Second equation:

4x + 2y = 120

Subtract 4x from both sides

2y = 120 - 4x

Divide both sides by 2

y = 60 - 2x

Now that the y's are isolated in both equation, you can put them into 1 equation. Where y = y:

y = 42 - x

y = 60 - 2x

42 - x = 60 - 2x

Add 2x to both sides

42 + x = 60

Subtract 42 from both sides

x = 18

Since x is the number of cows, we know that Farmer Brown has 18 cows.

Now we can substitute the x value into one of the equations:

y = 42 - x

y = 42 - (18)

y = 24

The number of chickens is represented by y, so there are 24 chickens.
