Answer:
Ax + By = C the answer is C 1/2x+2y=7
Step-by-step explanation:
Answer: 0.243.
Step-by-step explanation:
The probability in this case is approcimated by the probability distribution formula for random variables. This formula is denoted as:
P(X=r) = nCr * p^r * q^n-r
Where n = selected number to be sampled and in this case, n= 3
r = varied number of sample and in this case, r=1
P = probability of success and in this case p = 0.10
q = 1-p=1-0.1 = 0.9
P(X=1) = 3C1 × 0.1¹ × 0.9²
P(X=1) = 0.243.
Answer:
D
Step-by-step explanation:
-x + y >= 2
first of all, it means it includes the line (the "=" part).
that eliminates B and C.
then just look at the line function itself :
-x + y = 2
y = x + 2
and now
y >= x + 2
so, everything above the line (and again including the line), as every y value greater than or equal to the result of the line function is valid.
Answer:
The total cost = $714
Step-by-step explanation:
Given
The total cost can be determined by adding the costs of all the pieces of equipment.
Thus,
Total cost = Monitor cost + Scanner cost + Keyboard cost + Printer cost
= $287 + $58 + $49 + $320
= $714
Therefore, the total cost = $714
Answer:
D
Step-by-step explanation:
the volume (V) of a cone is
V = 
πr²h
where r is the radius and h the perpendicular height to the base
here r = 12 and h = 16
V = π × 12² × 16 = 768π units³ → D
