1 answer:

3 0

The correct answer for the question that is being presented above is this one: "A. (3/8)." According to the general equation for conditional probability if P(AupsidedownuB) = (3/10) and P(B)= (2/5), then P(A|B) is 3/8.
Here are the following choices:
A. (3/8)
B. (1/2)
C. (3/4)
D. (1/16)

Answer:

The actual distance between the two rivers is 232.5 kilometers.

Step-by-step explanation:

GIven:

The scale on a map is 2 centimeters= 50 kilometres.Two rivers on a map are located 9.3 centimeters apart.

Now, to find the actual distance between the two rivers.

Let the actual distance between the two rivers is $x.$

The two rivers on the map is located apart of 9.3 centimeters.

According to the scale on the map is 2 centimeters = 50 kilometers.

So, 2 centimeters is equivalent to 50 kilometers.

Thus, 9.3 centimeters is equivalent to $x.$

Now, to solve by using cross multiplication method:

$\frac{2}{50} =\frac{9.3}{x}$

By cross multiplying we get:

$2x=465$

Dividing both sides by 2 we get:

$x=232.5\ kilometers.$

Therefore, the actual distance between the two rivers is 232.5 kilometers.

The answer is below

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.

Reflection is the flipping of a point about an axis. If a figure with point A(x, y) is reflected about the y axis, the new point is A'(-x, y)

The quadrilateral KLMN has vertices at K(-2, 6), L(-3, 8), M(-4, 4) and N(-3, 2). If the quadrilateral is reflected about the y axis, the new point is at:

K(2, 6), L(3, 8), M(4, 4) and N(3, 2)

The figure was plotted using geogebra online graphing tool.
