Trava [24]3 years ago
8 0

Answer:

y = -2x - 3

Step-by-step explanation:

-solve for y: y = 1/2x + 2

-perpendicular equals opposite slope: -2

-plug in the point: (1) = -2(-2) + b

                               1 = 4 + b

                                b = -3

put it all together: y = -2x - 3

The total cost to play paintball can be represented by the expression (48x+54). If Rocco and five friends split the cost equally
KonstantinChe [14]

Answer:

8x + 9

Step-by-step explanation:

The total number of people splitting the cost equally = Rocco and five friends = 6 people

The total cost to play paintball can be represented by the expression (48x+54)

The cost for each person is calculated as: The total cost to play paintball/ Total number of people

= (48x+54)/6

= 48x/6 + 54/6

= 8x + 9

Therefore, the cost for each person is

8x + 9

Every​ morning, my neighbor goes out walking. I observe that​ 20% of the time she walks with her​ beagle, 70% of the time she wa
Oduvanchick [21]

Answer:

No, This is not a valid Probability Distribution

Step-by-step explanation:

Probability [Neighbour walks with Beagle] = 20%

Probability [Neighbour walks with Golden Retriever] = 70%

Probability [Neighbour walks alone] = 30%

Disjoint Events are the events that have zero probability of occurring together. If all the three above items are disjoint, it means that it can never happen that two of them happen together.

The total (summed) probability of a valid probability distribution, with disjoint sets = 1 . In given case, total probability = 0.2 + 0.7 + 0.3 = 1.2 ; i.e > 1.

So, this probability distribution with stated disjoint events is not a Valid Probability distribution.
