Answer:

0.61

Step-by-step explanation:

The computation of the probability of the working of the system is shown below:

But before that first we have to find out the total probability of sub-system i.e 2,3 and 4 i.e

= 0.75\times0.8\times0.8

= 0.48

Now the working of the system probability is

= 1 - [(1 - probability of component 1) × (1 - sub system probability)]

= 1 - [(1 - 0.75) × (1 - 0.48)]

= 1 - 0.39

= 0.61

Please find the attachment for better understanding.

12345 [234]

9514 1404 393

Answer:

  √145 ≈ 12.04

Step-by-step explanation:

The length of the space diagonal is the root of the sum of the squares of the prism edge lengths:

  d² = a² +b² +c² = 6² +3² +10² = 145

  d = √145 ≈ 12.04 . . . inches

__

The face diagonal is found using the Pythagorean theorem in the usual way:

  f² = a² + b²

The space diagonal is the hypotenuse of the right triangle whose sides are the face diagonal and the remaining edge:

  d² = f² +c²

  d² = a² +b² +c²

__

Here is a diagram.

HELP ASAP!! WILL MARK BRAINLIST!! A LOT OF POINTSS
Fittoniya [83]

Answer:

Black = 84 cm^2

Blue = 84cm^2

gold = 60.2cm^2

1 ornament = 228.2 cm^2

100 ornaments - 22820 cm^2

Step-by-step explanation:

Black is a rectangle = A = l*w = 7*12 = 84 cm^2

We have 2 blue   This is a triangle  so multiply by 2  the area of a triangle

2 * A = 2(1/2 b*h) = bh = 12*7 = 84 cm^2

We have 2 gold   This is a triangle  so multiply by 2  the area of a triangle

2 * A = 2(1/2 b*h) = bh = 8.6*7 = 60.2 cm^2

The total surface area for one ornament is

84+84+60.2 = 228.2

100 ornaments

Multiply by 100

100 *228.2 = 22820 cm^2
