Answer:
B) Probability must always be between 0 and 1 (0% and 100%), inclusive.
Step-by-step explanation:
Required
Select all true statement(s)
Represent the probability of an event with p.
In probability, the range of values of p is: 
or 
This implies that:
or 0
or 1
Base on the above information:
(a) False; because the maximum is 1
(b) True because of the above range; 0 to 1 or 0% to 100%
(c) False; because the minimum is 0
(d) False; because (b) is true
Solution :
Let :
X = number of overtime hours
S = total weekly salary
S = 
S = 480 + 18X
E(S) = 
= 750
Mean of S = 750
Var (S) = 
Var(S) = 
= 5184
Variance of S = 5184
The standard deviation equals square root of 5184 = 72
Sorry wish I could help but I need to see the picture to answer the question. Sorry :-(
Answer:
x = 20°
Step-by-step explanation:
Since BD = CD then Δ BCD is isosceles and its base angles are congruent, so
∠ CBD = ∠ BCD = 80° , then
∠ BDC = 180° - (80 + 80)° = 180° - 160° = 20°
∠ ADC = 180° - (80 + 60)° ← sum of angles in triangle
∠ ADC = 180° - 140° = 40° , then
∠ BDC + x = 40°
20° + x = 40° ( subtract 20° from both sides )
x = 20°
Answer:
x=91, y=91, z=39
Step-by-step explanation:
the angles add up to 180 so find the difference ex. 51+38=89, 180-89=91 so x is 91
