The number 4 siblings are least likely to be selected

Probability is the likelihood of an event occurring or not. Probability value ranges from  impossibility(0) to certainty(1).

The lower the value, the less likely the event is bound to occur.

From the probability distribution table, the probability of having 4 siblings at the game is 0.

This is the lowest out of all the given values in the probability distribution table. Therefore, it is the least likely event.

Thus the number 4 siblings are least likely to be selected

The probability (in percentage form) is 3.6%, so the correct option is the last one.

First, Janet is assigned to a car. We want to find the probability that it is a red car. All the cars have the same probability of being assigned, then the probability of getting a red car is equal to the quotient between the number of red cars and the total number of cars:

p = 2/(8) = 1/4

Now there is 1 red car left and 7 cars in total left.

Sarah is next on line, the probability that she gets a red car will be:

q = 1/7

The joint probability (the probability of both of these events happening) is given by the product of the two individual probabilities, so we get:

P = (1/4)*(1/7) = 0.036

If we multiply this by 100%, we get:

P = 100%*0.036 = 3.6%

So the correct option is the last one.

Answer:
With respect to angle A, a is opposite, b is adjacent, c is the hypotenuse

With respect to angle B, b is opposite, a adjacent, and c is the hypotenuse.

Step-by-step explaination:

To find the opposite side of an angle of a right triangle - look at the side that is directly across from that angle.  For example, angle A shows that the side directly across from it is side a.

To find the adjacent side of an angle of a right triangle - look at the side that is right next to it and connected to the 90 degree angle.  For example, angle B shows that the side that is next to it and connected to the 90 degree angle is side b.

The hypotenuse will always be the longest side opposite the 90 degree angle.

Answer: A sphere (from Greek σφαῖρα—sphaira, "globe, ball") is a geometrical object that is a three-dimensional analog to a two-dimensional circle. A sphere is the set of points that are all at the same distance r from a given point in three-dimensional space. That given point is the center of the sphere, and r is the sphere's radius. The earliest known mentions of spheres appear in the work of the ancient Greek mathematicians.

Step-by-step explanation: The formula used to calculate the sphere radius is: r = ∛((3/4) · V / π) Symbols. r = Sphere radius; V = Sphere volume; π = Pi = 3.14159… The volume of Sphere. Enter the volume contained within a sphere. The radius of Sphere. This is the radius of a sphere that corresponds to the specified volume.

Step-by-step explanation:

Note:

Circumference of a circle = [tex]\pi d[/tex]

Where d = diameter

We are given the diameter is 20cm, d = 20

Circumference of circle = [tex]\pi d[/tex] = 20 [tex]\pi[/tex]

Also, perimeter of a rectangle = 2 times length + 2 times width

We are told the length = 18 , width = x

Perimeter of rectangle = 2 times 18 + 2 times x

Perimeter of rectangle = 36 + 2x

The question also tells us that the circumference of the circle is EQUAL to the perimeter of the rectangle:

So this means:

Since Circumference of circle = 20[tex]\pi[/tex]  ,

Perimeter of rectangle = 36 + 2x .

We can write:

Circumference of circle = perimeter of rectangle

20[tex]\pi[/tex]   = 36 + 2x

Subtract 36 from both sides

20[tex]\pi[/tex] - 36   = 2x

Divide both sides by 2 to solve for "x".

x = [tex]\frac{20\pi - 36 }{2} = ?[/tex]

Answer:

( a − 1 + b )( a − 1 − b )

.

Answer:

(a−1+b)(a-1−b)

Step-by-step explanation:

The fixed charge is about 5 pound. For extra 6 km, extra cost is about 9 pound

A linear equation is in the form:

y = mx + b

Where m is the rate of change and b is the initial value of y.

From the graph:

The fixed charge is about 5 pound.

Using the point (0, 5) and (20, 35)

Charge per mile = (35 - 5) / (20 - 0) = 1.5 pound per mile

For extra 6 km, extra cost = 1.5 * 6 km = 9 pound

L = lengh

W = width

french reasoning ( hello from France ) !

The base of the house is a rectangle where the length of a rectangle is 8 more than the width.

=> L = W + 8

and

Its area is 240 ft sq

W x L = 240

L = W + 8

W x L = 240

=> W x (W+8) = 240

W² + 8W - 240 = 0

Δ = 8² - 4*1*(-240) = 32²

W' = (-8 + 32) / 2 = 12 ft

W'' = (-8 - 32) / 2 = impossible

at the end

W the width = 12 ft

and then the lengh = 12 + 8 = 20

area = 12 x 20 = 240 ft²

The maximum revenue is $320,000

Step-by-step explanation:

To find the maximum of a function f, the procedure is as follows:

The revenue function for a bicycle shop is

R(x)=xp(x), where p(x)=800-0.5x. Substituting:

[tex]R(x)=x(800-0.5x)=800x-0.5x^2[/tex]

Find the first derivative of R:

R'(x)=800-x

Equate to 0:

800-x=0

Solve:

x=800

There is only one critical point. Substitute it into the revenue function:

[tex]R(800)=800(800)-0.5(800)^2=320,000[/tex]

The maximum revenue is $320,000
