Missing part:

What is the probability that an international flight leaving the US is delayed in departing given that the flight is a transpacific flight?  

Answer:

P(D|P) = 0.50

Step-by-step explanation:

Given

P(D) = 0.26

P(P) = 0.50

P(D\ and\ P) = 0.13

The question illustrates conditional probability and it is represented as:

P(D|P)

This is then calculated as:

P(D|P) = \frac{P(D\ and\ P)}{P(D)}

So, we have:

P(D|P) = \frac{0.13}{0.26}

P(D|P) = 0.50

Right triangles abc and dbc with right angle c are given below. If cos(a)=15,ab=12 and cd=2, find the length of bd.
dmitriy555 [2]

see the attached figure to better understand the problem

we have that

cos(A)=\frac{1}{5} \\ AB=12\ units\\ CD=2\ units

Step 1

<u>Find the value of AC</u>

we know that

in the right triangle ABC

cos (A)=(AC/AB)\\AC=AB*cos(A)

substitute the values in the formula

AC=12*(1/5)\\ AC=2.4\ units

Step 2

<u>Find the value of BC</u>

we know that

in the right triangle ABC

Applying the Pythagorean Theorem

AB^{2} =AC^{2}+BC^{2}\\ BC^{2}=AB^{2} -AC^{2}

substitute the values

BC^{2}=12^{2} -2.4^{2}\\BC^{2}= 138.24\\ BC=11.76\ units

Step 3  

<u>Find the value of BD</u>

we know that

in the right triangle BCD

Applying the Pythagorean Theorem

BD^{2} =DC^{2}+BC^{2}

substitute the values  

BD^{2} =2^{2}+11.76^{2}

BD=11.93\ units

therefore

<u>the answer is</u>

the length of BD is 11.93 units

INSCRIBED ANGLES PLZ HELP ASAP
Taya2010 [7]
The answer is 46°.

The measure of an inscribed angle is equal to (1/2) the measure of the intercepted arc. 

That means that, since ADC is 23 degrees, doubling that gives you 46 degrees, the measure of the intercepted arc.

Central angles are equal to the measure of the intercepted arc, which in this case is the same arc we just calculated.

Therefore it's 46.

A bakery sells 4 dozen cupcakes every 3 hours. If the bakery is open 8 hours each day, how many days does it take to sell 640 cu
zmey [24]

5 days does it take to sell 640 cupcakes.

Given:

A bakery sells 4 dozen cupcakes every 3 hours.

If the bakery is open 8 hours each day.

4 dozen cupcakes = 4*12 cupcakes

= 48 cupcakes

48 cupcakes = 3 hours

divide by 3 on both sides

3hours/3 = 48/3 cupcakes

1 hour = 16 cupcakes

Number of cupcakes for 8 hours = 8 * 16 = 128 cupcakes.

128 cupcakes sells in one day.

To sell 640 cupcakes = 640/128

= 5 days.

Therefore 5 days does it take to sell 640 cupcakes.
