Gala2k [10]

Answer: 14.5

Step-by-step explanation:

Given data:

Success rate = 80% = 0.8

No of flights = 7

No of failures = 1 – 0.8 = 0.2

Solution

at least 3 flights are on time is

= 7C3 * (0.80)^3 * (0.80)^1  +  7C7 * (0.80)^7 * (0.80)^1

= 35 * 0.512 * 0.8 + 1 * 0.21 * 0.8

= 14.336 + 0.168

= 14.5

Which of the following are equivalent ratios?<br>A: 12 : 16<br>B: 3 : 5<br>C: 2 : 3<br>D: 6 : 8​
Alla [95]

The equivalent ratios are A and D.

Here's an explanation:

When you look at D, you see that 12 is a multiple of 6, and 16 is a multiple of 8. So you know that it looks like they're equivalent. Then you test it out, 12/2=6. 16/2=8. so 12:16 = 6:8. Eyeballing it first can save time sometimes.

Can you help me with this question?
galina1969 [7]

Answer:

42ft

Step-by-step explanation:

Area of a triangle = 1/2 * base * height

So that little triangle section:

 1/2 * 2 * 3 = 1/2 * 6 = 3

Now we do the rectangle Section:

Area of a rectangle = length * width

So that rectangle is 3 * 7 = 21

If you eliminate those two shapes, you are left with a trapezoid.

Area of a trapezoid is 1/2 * (base 1 + base 2) * height

Base 1 is 3 which is the width of the rectangle.

Base 2 is the 6.

The height is the given 11 feet subtracted by the 7 feet from the length of the rectangle which is 4.

Plug all this in to the formula you get 1/2 * (6 + 3) * 4 = 1/2 * 9 * 4 = 1/2 * 36 = 18.

Now add all of your areas together;

21 + 3 + 18 = 24 + 18 = 42
