Answer:

B represents a function.

Step-by-step explanation:

Recall these characteristics of a "function:"

Only one y-value can be associated with each x-value.

Thus, A could not represent a function because there are two points with x = 1 and two different y-values: (1, 1) and (1, -2).

B represents a function because for each input (x-value) there is one and only one y-value associated.

C not a function: (2, 3) and (2, -3) have two different y-values associated with one x-value (2).

D not a function: (-3, 4) and (-3, -4) (see A and C, above)

The probability of event A is 0. 48, the probability of event A and B is 0. 21, and the probability of events A or B is 0. 89. W

Mice21 [21]

Probabilities are used to determine the chances of an event

The probability of event B is 0.62

The probabilities are given as:

$\mathbf{P(A) = 0.48}$

$\mathbf{P(A\ and\ B) = 0.21}$

$\mathbf{P(A\ or\ B) = 0.89}$

To calculate the probability of event B, we make use of the following formula

$\mathbf{P(A\ and\ B) = P(A) + P(B) - P(A\ or\ B)}$

So, we have:

$\mathbf{0.21 = 0.48 + P(B) - 0.89}$

Collect like terms

$\mathbf{P(B)= -0.48 +0.21 + 0.89}$

$\mathbf{P(B)= 0.62}$

Hence, the probability of event B is 0.62

PLEASE HELP ME GRAPH THIS

spin [16.1K]

Answer:

$\huge\boxed{(12,80),(10,65)}$

Step-by-step explanation:

The line given has a slope of 7.5 and a point at (12, 80)

Because of the slope, simply subtract 2 from the x and subtract 15 from the y to get another point, at (10, 65)

Thus, simply put your points at (10, 65) and (12, 80)

Hope it helps and let me know if you want me to elaborate.

The Saxena family plans to install a light to illuminate part of their rectangular yard. Nikki and Dylan each proposed a differe

The correct situation for the given condition are as follows:

C) Both proposed placements will light the same sized area.

F) Dylan's proposed placement will light exactly half of the yard.

<h3>What is Area of Triangle?</h3>

The area of a triangle is defined as the total space occupied by the three sides of a triangle in a 2-dimensional plane. The basic formula for the area of a triangle is equal to half the product of its base and height, i.e., A = 1/2 × b × h.

The area of a triangle = (base x height) / 2

and,

both lights illuminate the same base and height = (60 x 38) / 2

= 1,140 sq ft

Both Dylan's and Nikki's proposed placement will lit exactly half of the yard.

The yard's total area = 60 x 38 = 2,280 sq ft,

which is twice the area lit by the lights.

Thus, The correct situation for the given condition are as follows:

C) Both proposed placements will light the same sized area.

F) Dylan's proposed placement will light exactly half of the yard.
