Svetllana [295]3 years ago

The event of the machine working is A\cap B\cap C\cap D, and since the components operate independently, we have

P(A\cap B\cap C\cap D)=P(A)P(B)P(C)P(D)

so just multiply the given probabilities together,

P(A\cap B\cap C\cap D)=0.99^2\cdot0.94\cdot0.93\approx0.8568

Find the height of a right circular cone if the slant height is 4 units and the radius is 2 units
k0ka [10]

The slant height of the right circular cone will be  l=2\sqrt5}

<h3>What is slant height of cone? </h3>

The formula for the slant height of the cone is given as:

l^2=r^2+h^2

Here we have

r=2 units

h=4 units

By putting the values we will get

l=\sqrt{4^2+2^2

l=\sqrt{16+4

l=\sqrt{20}

l=2\sqrt{5}

Hence the slant height of the right circular cone will be  l=2\sqrt5}

To make sure that a given parallelogram is a rectangle, at least hon many of
zmey [24]

Answer:

D. One

Step-by-step explanation:

     A parallelogram will have two sets of equal sides. Since we have that fact, all we need to know are the angles.

     A quadrilateral will have a total of 360° in its angles. If only one angle is equal to 90°, then we can do <u>the math</u> to figure out that all the others must be 90° as well. A rectangle is a parallelogram with the opposite sides being parallel and all the angles being 90°. This then answers the question.

     "<u>The Math</u>"

-> Keep in mind there will be four angles

-> Once we subtract the first angle of 90°, we will have three angles left. Hence why we divide by 3.

360° - 90° = 270°

270° / 3 = 90° ✓

Help!!! Assignment due in 20 minutes!!
Vitek1552 [10]

Answer:

2

Step-by-step explanation:

The answer would be 2 because it reduces to the same system of equations as the original, which I knew since the first equation was the same and if you divide everything in the second by 2, you'll get 3x-y=8. :)

The area of a circle is 706.9 square inches. Find the radius
antoniya [11.8K]

Answer:

15 inches

Step-by-step explanation:

The area of a circle is pi r^2. We basically have to work backwards. I divided it fist by 3.14 which is the value of pi. I got 225.127, but I rounded it to 225. I found the square root of this which is 15. If we check the work. 15^2 is 225, and 225 times pi is 706.9.
