What is the probability of tossing 3 heads in a row when flipping a coin?

Answer:

Step-by-step explanation:

NOTE:__________________________________________

applying a sales tax of 8% on an item means multiplying its original price by (1+8%).__________________________________________

The needed amount of money:

  29.99×(1+8%)+16.99×(1+8%)

= 29.99×(1+(8÷100))+16.99×(1+(8÷100))

= 50.7384

Answer:

I think the answer is 4 1/2 out of 30 chance.

Step-by-step explanation:

The probability of selecting two solid chocolates in a row is 4/145.

To calculate the probability of selecting two solid chocolates in a row, we need to consider the probability of selecting a solid chocolate on the first draw and the probability of selecting a solid chocolate on the second draw, given that a solid chocolate was selected on the first draw.

There are a total of 30 chocolates, with 9 solid chocolates. Therefore, the probability of selecting a solid chocolate on the first draw is 9/30.

After eating the first chocolate, there are now 29 chocolates left in the box, with 8 solid chocolates remaining. So the probability of selecting a second solid chocolate is 8/29.

Since the two events are independent, we can multiply the probabilities of each event to find the probability of both events occurring:

Probability of selecting two solid chocolates = (9/30) * (8/29) = 4/145.

Answer:

A line passing through (1, 3) and (5, 11)

Rate of change = 2

Step-by-step explanation:

Let's get the rate of change for each line:

A line passing through (-1, 4) and (1, 7).

A line passing through (1, 3) and (5, 11).

A line passing through (1, 1) and (4, -3).

A line passing through (0, 6) and (12, 9)

Comparing the values of r, we can see the greatest one is 2 for the line passing through (1, 3) and (5, 11)

The volume of the can is 328, 268. 16 mm³.

Volume is a mathematical term used to describe how much three-dimensional space an item or closed surface occupies.

The area that any three-dimensional solid occupies is known as its volume. These solids can take the form of a cube, cuboid, cone, cylinder, or sphere.

We have,

Radius = 66/ 2= 33 mm

Height= 96 mm

So, volume of Can

Answer:

28.12 cm^2

Step-by-step explanation:

I don't know what "length" and "bottom" mean as dimensions in a parallelogram, but if they are a side length and an altitude drawn to that side, then the area is 7.6 cm * 3.7 cm = 28.12 cm^2.

1. Translation of Quadrilateral

A translation rule tells you how much to add to the values of x and y.

In your translation, the value of x increases from -5 to +1 — a distance of 6 units.

The value of y decreases from +4 to +2 — a distance of 2 units.

They're same side interior angles because since it's a parallelogram, the lines are parallel, and in this case, AB and CD are the parallel lines, AD is the transversal, and therefore, x and 115 are same side interior.

Same side interior angles are supplementary so x + 115 = 180

x = 180 - 115 = 65

x = 6

Step-by-step explanation:

x = 6 (-6 can't be a length)

Answer:

The Answer Is 6

Step-by-step explanation:

By Pythagoras Theorem

(AC)^2 = (AB)^2 + (BC)^2

(AB)^2 = (AC)^2 - (BC)^2

(AB)^2 = (10)^2 - (8)^2

(AB)^2 = 100 - 64

(AB)^2 = 36

(AB) = 6

Answer: e = 10

Step-by-step explanation: 9e + 4 = -5e + 14 + 13 e

Now lets bring the variables and numbers on a different side

Remember that when the numbers go to the other side the sign changes

so 4 - 14 = -9e + 13e -5e

-10 = -e

10 = e

if plug in both equations on a graph then you will see that when e = 10 the lines meet at 94.

Answer:

[tex]e=10[/tex]

Step-by-step explanation:

[tex]9e+4=-5e+14+13e[/tex]

Simplify both sides by combining [tex]-5e+13e[/tex] :

Isolate the variable e. Subtract  8e from both sides:

Answer:

111 pounds

Step-by-step explanation:

A boy holding a stack of 9 identical books steps on a scale and weighs 138 pounds.

If the boy's weight is represented as B and the books are represented as b, this implies that:

B + 9b = 138

The boy then holding a stack of 3 of the same books again steps on the scale and weighs 120 pounds. This implies that:

B + 3b = 120

This has yielded two simultaneous equations:

B + 9b = 138

B + 3b = 120

We can solve by subtracting the second from the first.

B + 9b = 138

- (B + 3b = 120)

-----------------------

=> 6b = 18

b = 18 / 6 = 3 pounds

This means that each book weighs 3 pounds.

Putting b back in the second equation:

B + (3 * 3) = 120

B + 9 = 120

B = 120 - 9

B = 111 pounds

Therefore, the boy weighs 111 pounds.

Answer:

The boy would weigh 111 lbs.

The length of the fence is 38 yards

These are the expressions

1. Perimeter = 2l+ 2w

2. Perimeter = 2(l+w)

Step-by-step explanation:

This problem bothers on the mensuration of flat shapes, a rectangle.

The length of the fence is the perimeter of the garden which is the expression that Chole could use

1. Perimeter = 2l+ 2w

2. Perimeter = 2(l+w)

Length = 11 yards

Width = 8 yards

Perimeter = 2(11)+ 2(8)

Perimeter = 22+16

Perimeter = 38 yards

Answer:

  1229 km

Step-by-step explanation:

The missing angle is ...

  180° -60° -75° = 45°

Knowing that, the Law of Sines can be used to find the side opposite the 75° angle.

  ?/sin(75°) = 900 km/sin(45°)

  ? = (900 km)sin(75°)/sin(45°) ≈ 1229.423 km

The UFO is about 1229 km from KA-12.

The volume of the sphere is 500/3 π cubic units. What is the value of x?  

x = radius

Answer:

x = 5 units

Step-by-step explanation:

The volume for a sphere can be represented as follows

volume = 4/3πr³

volume = 500/3 π

x = radius

volume = 4/3πx³

500/3 π = 4/3 × π × x³

multiply both sides by 3/4

500/3 × π × 3/4 = π × x³

125π = πx³

divide both sides by π

x³ = 125π/π

x³ = 125

cube root both sides

x³ = ∛125

x = 5 units

Y = sin (x+90) is the same as a Y = cos x graph, so Y = sin(x+90) is our answer

Answer:

a) Length [tex]x + 12[/tex], Width [tex]x - 3[/tex], b) [tex]x = 3[/tex]

Step-by-step explanation:

a) The expressions for the length and width of the parallelogram can be determined by factorizing the polynomial:

[tex]A = x^{2} + 9\cdot x - 36[/tex]

[tex]A = (x+12)\cdot (x-3)[/tex]

Length

[tex]x + 12[/tex]

Width

[tex]x - 3[/tex]

b) Since area is a positive variable, the set of solutions encompass all values of x such that area is zero o greater. Then, there are two interval where A is positive:

- When both binomials are negative.

[tex]x \leq 3[/tex] and [tex]x \leq -12[/tex]

[tex]x \leq -12[/tex]

- When both binomials are positive.

[tex]x \geq 3[/tex] and [tex]x \geq -12[/tex]

[tex]x \geq 3[/tex]

Since x is an integer, x must be positive and therefore the least possible value of x is:

[tex]x = 3[/tex]

Answer:

Step-by-step explanation:

To work out 60% of 52 you would first need to find 10%. You can do this by dividing 52 by 10, this gives you 5.2.

The final step is to multiply 5.2 by 6, this gives 31.2. This is because in order work out 60% you multiply 10% by 6.

1) Divide 52 by 10.

[tex]52/10=5.2[/tex]

2) Multiply 5.2 by 6.

Answer:

Step-by-step explanation:

Given that, a series of triangle,

For the sine and cosine to be equal, then,

Sinθ = Cosθ

From, trigonometry identities

Sinθ = Cos(90-θ)

Then,

θ = 90-θ

θ + θ = 90

2θ = 90

θ = 90 / 2

θ = 45°

From the triangle given, using trigonometry ratio,

Sinθ = opposite / hypotenuse.

Sinθ = 20 / 25

Sinθ = 0.8

θ = arcsin(0.8)

θ = 53.13°

The other angles at the triangle is

90-53.13 = 36.87°.
