The system of equations graphed below has how many solutions ?
2 answers:
Answer:
Option A. 0 solutions.
Step-by-step explanation:
The system of equations graphed has two equations.
and
Here equation 1 and 2 both have the same slope = -3/2
Therefore these lines are parallel.
Since parallel lines never meet at a point so the solutions of this systems of the equations will be zero.
Option A. 0 is the correct option.

Given:
The lifetimes of the individual items are independent exponential random variables.
Mean = 200 hours.
Assume, Ti be the time between ( )st and the
failures. Then, the
are independent with
being exponential with rate
Therefore,
a)
The variance is given by,
Answer: A. y = 16 x
B. 8 days
Step-by-step explanation:
A) Here, 16 Fluid ounces of milk is used for breakfast every morning.
In one day the consumption of milk = 16 fluid ounces
In x days the consumption of milk = 16 x fluid ounces
Thus, if y be the total milk in ounces that is used in x days,
The required function,
y = 16 x
B) In 1 day, consumption of milk = 16 ounces
⇒
⇒
⇒
Since, 128 ounces = 1 gallon
⇒
In 8 days, 1 gallon of milk will consumed.
