A person draws a card from a hat. Each card is one color with the following probabilities of being drawn: 1/10 for red, 1/5 for

Kay [80]

Answer:

$\dfrac{1}{4}$

Step-by-step explanation:

We are given that a card is drawn from a hat.

Probability that a red card is drawn, P(red) = $\frac{1}{10}$

Probability that a blue card is drawn, P(blue) = $\frac{1}{5}$

Probability that a black card is drawn, P(black) = $\frac{1}{20}$

Probability that a pink card is drawn, P(pink) = $\frac{1}{5}$

All these events are mutually exclusive i.e. they do not have anything in common.

For any two events A and B which are mutually exclusive, with probability P(A) and P(B), the probability that any one of the two events occur:

$P(A\cup B) = P(A) + P(B)$

Here event A can be thought of as drawing a blue card and

event B can be thought of as drawing a black card

So, P(blue or black) = P(blue) + P(black)

$\Rightarrow \dfrac{1}{5}+\dfrac{1}{20}\\\Rightarrow \dfrac{4+1}{20}\\\Rightarrow \dfrac{5}{20}\\\Rightarrow \dfrac{1}{4}$

So, the probability that a blue or black card is drawn from the hat:

$\dfrac{1}{4}$

Which undefined geometric term is described as a location on a coordinate plane that is designated by an ordered pair, (x, y)?

vlabodo [156]

Answer: A point.

Step-by-step explanation:

There are three undefined terms in geometry :

1) point 2) line 3) plane

A point has zero dimension and it is used to locate a figure on coordinate plane.

The location of figure is represented by a point in the form of ordered pairs (x,y), on coordinate plane where x= abscissa and y= ordinate.

A line is one dimensional straight indefinite path on plane that has no width.

A plane is a two-dimensional flat surface that extends upto infinity.

So , the undefined geometric term is described as a location on a coordinate plane that is designated by an ordered pair, (x, y) is A point.

3b+4b^2-a^3;a=3 and b=-5

Alik [6]

Equation: 3b+4b^2-a^3
Given: a=3 & b=-5

Plug 3 in for (a) and -5 in for (b):
3(-5)+4(-5)^2-(3)^3

Now follow PEMDAS:
3(-5) + 4(-5)^2 - (3)^3
-15 + 4(-5)^2 - (3)^3
-15 + 100 - (3)^3
-15 + 100 - 27
85 - 27
58
the asnwer is 58.
