Answer: Option A.
Step-by-step explanation:
The joint probability for two different things is equal to the product of the individual probabilities.
For contractor A we have:
Prob that the job is done in time = 0.95
Prob that the job is done within the budget = 0.97
Prob of both things at the same time P = 0.95*0.97 = 0.92
For company B we have:
Prob that the job is done in time = 0.98
Prob that the job is done within the budget = 0.93
Prob of both things at the same time P = 0.98*0.93 = 0.91
Then the best contractor is contractor A, (with a joint probability of p = 0.92) and the correct option is option A.
Answer:
D
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
here (h, k) = (- 3, - 6), thus
y = a(x + 3)² - 6
To find a substitute (0, 0) into the equation
0 = 9a - 6 ⇒ a =
= 
y =
(x + 3)² - 6 ← in vertex form
Expand (x + 3)² and distribute by 
y =
(x² + 6x + 9) - 6
=
x² + 4x + 6 - 6
=
x² + 4x ← in standard form

Step-by-step explanation:
The answer is 15
Answer:
the correct answer is 1 because it looks like they are doing it by odd numbers.
