Answer:

4 times bigger

Step-by-step explanation:

1. The area of an object dilated by a scale factor (SF) will be equal to (SF)^2.

2. For example, let's say the base and height of Triangle A is 4 and 8. The area would be 16 units squared. The base and height of Triangle B would be 8 and 16. The area would be 64 units squared.

3. As you can see from the aforementioned example, the SF (2) was squared  and then multiplied by 16 to get 64.

Therefore, Triangle B's area is 4 times bigger than Triangle A's area.

The probability that it is gold is (1/3).

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty. The likelihood that an event will occur increases with its probability. If two events are mutually exclusive, then there is a 0 percent chance that they will both happen at the exact moment. Two events are said to be mutually exclusive if they share no elements (their intersection is the empty set). Consequently, P(A∩B)=0.

Let A be the event that a gold marble is picked.

Let B₁ and B₂ be the event that the first bag is chosen and the second bag is chosen respectively.

Given: P (B₁ ) = 2.P(B₂)

Also, P(B₁) + P(B₂) = 1

∴ 2P(B₂) + P(B₂) =1

3P(B₂) = 1

P(B₂) = 1/3 and  P(B₁) = 2/3

Now

P(A)

= P(A∩(B₁∪B₂))

= P[(A∩B₁)∪(A∩B₂)]

Probability adds up because the events are mutually exclusive

= P(A∩B₁) + P(A∩B₂)

= P(B₁). P(A/B₁) + P(B₂). P(A/B₂)

= (2/3)×(3/16) + (1/3)×(15/24)

= (1/3)

To calculate the discharge through the circular channel, we can use Manning's equation, which relates the flow rate (Q) to the channel properties and flow conditions. Manning's equation is given by:

Q = (1/n) * A * R^(2/3) * S^(1/2)

where:

Q is the discharge (flow rate)

n is Manning's coefficient (0.014 in this case)

A is the cross-sectional area of the channel

R is the hydraulic radius of the channel

S is the slope of the channel bed

First, let's calculate the cross-sectional area (A) of the circular channel. The diameter of the channel is given as 6m, so the radius (r) is half of that, which is 3m. Therefore, the area can be calculated as:

A = π * r^2 = π * (3m)^2 = 9π m^2

Next, let's calculate the hydraulic radius (R) of the channel. For a circular channel, the hydraulic radius is equal to half of the diameter, which is:

R = r = 3m

Now, we can calculate the slope (S) of the channel bed. The given slope is 1 in 600, which means for every 600 units of horizontal distance, there is a 1-unit change in vertical distance. Therefore, the slope can be expressed as:

S = 1/600

Finally, we can substitute these values into Manning's equation to calculate the discharge (Q):

Q = (1/0.014) * (9π m^2) * (3m)^(2/3) * (1/600)^(1/2)

Using a calculator, the discharge can be evaluated to get the final result.

The length of the rectangular classroom will be 8 inches on the scale drawing.

What is a rectangle defined as?

Rectangles are four-sided polygons having internal angles of 90 degrees. At each corner or vertex, two sides meet at right angles. The rectangle differs from the square in that its opposite sides are of equal length.

If one side of a rectangle is 20 cm long, the other side must be 20 cm long as well.

Two diagonals cross form a rectangle. Both diagonals are the same length.

P = 2 (Length + Width) defines the perimeter.

Rectangle Area=Length*Breadth

Now,

As total length of room =36 feet

and 9 feet = 2 inch on drawing scale

then length of classroom on  drawing scale is = 36/9*2

=8 inch

Hence,

            The length of the rectangular classroom will be 8 inches on the scale drawing.

The probability that Francis accumulates n heads before Runhan accumulates m heads is \(P_n\), m = \(pP_n_-_1,_m + (1 - p)(1 - P_m,_n)\).

The probability of an occurrence is a number used in science to describe how likely it is that the event will take place. In terms of percentage notation, it is stated as a number between 0 and 1, or between 0% and 100%. The higher the likelihood, the more probable it is that the event will take place.

probability of getting a head on a single toss of a coin is p,

P(H) = p

Francis starts and continues to flip the coin until a tail shows up,

Condition on the initial flip. If it lands on heads then Francis will win with probability of

\(P_n_-_1, m\)

whereas if it lands tails then Runhan will win with the probability \(P_m\), n and so Francis will win with the probability of :

1 - \(P_m\), n.

Step-by-step explanation:

the slope formula is y divided by x. it goes down 1 unit and right 3 units. so

The matrix representation of the linear transformation T: R² → R² defined by T(x) = Ax relative to the basis B = {-2, 1} is: [[1, -2],

                                                                           [3, 2]]

To find the matrix representation of the linear transformation T, we need to determine how T acts on the basis vectors of the domain and express the resulting vectors in terms of the basis vectors of the codomain. In this case, the basis B for both the domain and codomain is {-2, 1}.

We apply the transformation T to each basis vector in B and express the resulting vectors as linear combinations of the basis vectors in B. For T(-2), we have:

T(-2) = A(-2) = -2A

So, T(-2) can be expressed as -2 times the first basis vector (-2). Similarly, for T(1), we have:

T(1) = A(1) = A

Therefore, T(1) can be expressed as the second basis vector (1).

Putting these results together, we construct the matrix representation of T with respect to the basis B by arranging the coefficients of the linear combinations in a matrix:

[[1, -2],

[3, 2]]

This matrix represents the linear transformation T: R² → R² defined by T(x) = Ax relative to the basis B = {-2, 1}.

A. cos 159 < 0

Step-by-step explanation:

just did it!

Out of the given statement first statement i.e. cos 159⁰ < 0 is correct.

Quadrant is the region enclosed by the intersection of the X-axis and the Y-axis. On the cartesian plane when the two axes, X-axis and Y-axis, intersect with each other at 90º there are four regions formed around it, and those regions are called Quadrants.

Here, angle 159⁰ lies between 90⁰ and 180⁰.

Region between 90⁰ and 180⁰ is 2nd Quadrant.

In second quadrant Sin and cosec are positive, rest all other trigonometric ratios are negative in 2nd quadrant.

Thus, cos will be negative in second quadrant. cos 159⁰ < 0.

The length of the base is 16 inches.

To find the length of the base of the triangular pane of glass, we can use the formula for the area of a triangle which is:

Area = (1/2) x base x height

We are given that the height of the pane is 32 inches and the area is 256 square inches. Substituting these values into the formula, we get:

256 = (1/2) x base x 32

To isolate the base, we can divide both sides by (1/2) x 32, which simplifies to 16. This gives us:

256 ÷ 16 = base

Simplifying the left side of the equation, we get:

16 = base

Therefore, the length of the base of the pane is 16 inches.

In summary, the triangular pane of glass has a height of 32 inches and an area of 256 square inches. To find the length of the base, we use the formula for the area of a triangle and solve for the base.
