Answer:
0.756
Step-by-step explanation:
It is given that a machine has four components, A, B, C, and D.
If these components set up in such a manner that all four parts must work for the machine to work properly.
We need to find the probability that the machine works properly. It means we have to find the value of 
.
If two events X and Y are independent, then
Assume the probability of one part working does not depend on the functionality of any of the other parts.
Substitute the given values.
Therefore, the probability that the machine works properly is 0.756.

Answer:
The Question is Incomplete still What i understood I let you Explain.
x = 78°
Step-by-step explanation:
Let
m∠ A = 78°
m∠ B = 56°
m∠ C = 100°
m∠ D = (x + 48)°
Be angles of Quadrilateral.
To Find:
x = ?
Solution:
Property of a Quadrilateral sum of the measures of the angle is 360°.
∴ m∠ A + m∠ B + m∠ C + m∠ D = 360°
Substituting above given values we get
∴ 78° +56° + 100° + ( x + 48° ) = 360°
∴ x + 282° = 360°
∴ x = 360° - 282°
∴ x = 78° ........... which the required answer
