Mathematics
1 answer:
Vika [28.1K]3 years ago

Answer: DC=30.5

Step-by-step explanation:

Use trigonometry to solve this question

  • sin=O/H
  • cos=A/H
  • tan=O/A

----------------------------------------------------------

First Step: find BD

- AB relative to 54° is [hypotenues]

- BD relative to 54° is [opposite]

- Therefore, we need to use O/H, which is Sin

- sin(54°)=O/20=20·sin(54°)=16.2

Second Step: Find DC

- DC relative to 28° is [adjacent]

- BD relative to 28° is [opposite]

- Therefore, we need to use O/A, which is tan

- tan(28°)=16.2/A=16.2/tan(28°)=30.5

Hope this helps!! :)

At a car and truck dealership the probability that a vehicle is white is 0.25 the probability that it is a pickup truck is 0.15
Kisachek [45]

Step-by-step Answer:

Given:

W=vehicle is White

T=vehicle is a pick-up Truck

P(W and T)=0.06

P(W)=0.25

P(T)=0.15

We need the conditional probability that a vehicle is white, given that it is a pick-up truck:

P(W | T)

= P(W and T) / P(T)

= 0.06 / 0.15

=0.4
