Answer:
For a continuous random variable X, P(20 ≤ X ≤ 40) = 0.15 and P(X > 40) = 0.16.
Step-by-step explanation:
Here, P(x > 40) = 0.16
a). P(x < 40) = 1 - P(x > 40)
= 1 - 0.16
= 0.84
b). P(x < 20) = 1 - 
= 1 - {P(20 ≤ X ≤ 40) + P(X > 40)}
= 1 - (0.15 + 0.16 )
= 1 - 0.31
= 0. 69
c). P(x = 40) = 0; The probability that a continuous variable assume a particular value is zero.
Answer:
The significant figure of the result is 138.8
Step-by-step explanation:
24.78*(37.3 - 31.72)
Solving the bracket first:
37.3 - 31.72 = 5.58
A zero is added to 37.3 before the substraction, so;
37.3 - 31.72 = 37.30 - 31.72 = 5.58
Following the rule of significant figure; we have the answer of the substraction as 5.6 since the least number of significant is one decimal place.
The new expression will be:
24.78 * 5.6 = 138.768
Therefore, the result of our expression 138.8 by following the rule of significant figure

Hope this helped I only did like 1 lesson on functions
Answer:
Option B) y = 50
Step-by-step explanation:
We are given the following information:
Two parallel lines are crossed by a transversal.
The attached image shows the intersection of transversal and the angles.
As clear from the image, the given pair of angles form alternate interior angles.
If two parallel lines are cut by a transversal, then the pairs of alternate interior angles are congruent or equal
Thus, y = 50 degree
