Answer:
-x^2+6x+2
Step-by-step explanation:
1. Calculate
3x^2+5x-8-4x^2+x-6 = -x^2+6x+2
Answer:
Step-by-step explanation:
Given that the possible values of X, the number of components in a system submitted for repair that must be replaced are 1,2,3, and 4 with corresponding probabilities 0.15, 0.35, 0.35, and 0.15 respectively.
X 1 2 3 4
p 0.15 0.35 0.35 0.15 1
x*p 0.15 0.70 1.05 0.60 2.50
a)E(x) = 2.50
By linearity property
E(5-x) = 5-E(x) = 2.50
b) If fees it 75 then charges would be
Else repair charges = 
II one is better
Given:
Figure of a parallelogram.
To find:
The values of x and y.
Solution:
If two parallel lines intersected by a transversal line, then the alternate interior angles are congruent.
(Alternate interior angles)


And,
(Alternate interior angles)


The value of x is 6 and the value of y is 42.
Therefore, the correct option is C.
