Answer:

0.335

Step-by-step explanation:

1. There is a 30 percent chance of a flight being delayed because of icy weather ,then the probability of being delayed is 0.3 and of being not delayed is 0.7.

2. If a flight is delayed because of icy weather, there is a 10 percent chance the flight will also be delayed because of a mechanical problem, then the probability of being delayed is 0.1 and the probabilty of not being delayed is 0.9.

3. If a flight is not delayed because of icy weather, there is a 5 percent chance that it will be delayed because of a mechanical problem (MP), then the probability of being delayed is 0.05 and the probabilty of not being delayed is 0.95. (See attached probability tree)

Delayed of icy weather - 0.3

Delayed of MP when weather is not icy - 0.7·0.05=0.035

Now, if one flight is selected at random from the airport in January, the probability that the flight selected will have at least one of the two types of delays is

0.3+0.035=0.335

Answer:

the answer is 4

Step-by-step explanation:

8x-1=5x+11

3x=12

x=4

Answer:

x = 28

Step-by-step explanation:

AB= AC

∠B = ∠C    {Angles opposite to equal sides are equal}

∠A + ∠B + ∠C = 180    {angle sum property}

3x + x + 20 + x + 20 = 180 {Combine like terms}

3x +x +x + 20 + 20 = 180

          5x + 40 = 180          {subtract 40 from both sides}

                   5x = 180 - 40

                  5x = 140      {divide both sides by 5}

                    x = 140/5

x = 28

Answer:

  14.7

Step-by-step explanation:

The law of sines tells you side lengths are proportional to the sine of the opposite angle.

  x/sin(46°) = 7/sin(20°)

  x = 7(sin(46°)/sin(20°)) ≈ 14.7

The value of x is about 14.7.

Answer:

48 girls!

Step-by-step explanation:

boys = 6x

girls = 8x

6x = 36

x = 36/6 = 6

girls = 8x = 8 x 6 =  48

I hope im right!

Answer:

Well since there aren't any specifics all you can be given is an equation on how to solve it, if a box has 6 sides and it's a cube then it will just be L*W=A then multiply that area by 6, that gives you the full surface area and if you want it for 150 boxes then just multiply whatever you got for the surface area by 150. It will be different if it's a rectangular box though, with that you must solve the surface area for 3 different pieces and multiply them all by 2 then add them all up and you get the surface area of that shape, then you multiply by 150 and that's your answer.

370 / 0.40 = 925 full marks

Answer:

3

Step-by-step explanation:

to find the parallel  of this line we need to find function with same slope

1) x+y=-2 ⇒ y=-x-2

2)x=1    

3) x-y=5  ⇒ y=x-5

4)y=1

so third

Answer:

13 quarts

Step-by-step explanation:

Remember this:

1 mug = 16 oz

1 quart = 32 oz

Find total quarts of coffee.

Setup proportion and solve for x ounces:

[tex]\frac{1 mug}{16 oz} =\frac{26 mugs}{xoz}\\\\x oz=16(26)=416 oz[/tex]

Setup another proportion to solve for x quarts and also use the 416 oz.

[tex]\frac{32oz}{1 qt} =\frac{416oz}{xqt} \\x=\frac{416}{32} = 13 qt[/tex]

The surface area of the composite solid is 165 [tex]feet^2[/tex].

We possess

4 triangles, each measuring 6 feet in height and 5 feet in base

4 rectangles, each measuring 5 feet long and 4 feet wide

1 square has side a = 5 feet.

The formula for a triangle's area is:

[tex]A_T=\frac{1}{2} bh[/tex]

Substitute:

[tex]A_T=\frac{1}{2} 5*6\\A_T=\frac{1}{2} 30\\A_T=15 ft^2[/tex]

Formula for calculating a rectangle's area:

[tex]A_R=lw[/tex]

Substitute:

[tex]A_R=5*4\\A_R=20 ft^2[/tex]

The formula for a square's area is as follows:

[tex]A_s=a^2[/tex]

Substitute:

[tex]A=s=5^2\\A_s=25 ft^2[/tex]

The composite solid's surface area is:

[tex]SA=4A_T+4A_R+A_s[/tex]

Substitute:

[tex]SA=4*15+4*20+25\\SA= 60+80+25\\SA=165 ft^2[/tex]

The composite solid has a surface area of 165 [tex]feet^2[/tex].

Step-by-step explanation:

A trapezoid is never a square. A trapezoid only has one pair of parallel lines and a square has two.

Answer:

Step-by-step explanation:

First do 4 -2 to get 2. Then do 30-15 to get 15. It’s 2:15.

You can also do this on a calculator by doing 4.15-2.30. You get 1.85

Remember that time is only up to 60 So you have to subtract 15 from 85 to get 60. So it’s 2 hours and 15 minutes. Hope this helps!

Answer:

45 minutes

Step-by-step explanation:

this is an over-estimate and the reason is 200/5=40 the closest one is actually 45 minutes
