The area of this rectangle is given by the quadratic function
Sonja [21]

<em>The function uses W as the variable but the options show only x's as the variable, so I'm asumming W in the answer</em>

Answer:

0 < W < 50

Correct option: A

Step-by-step explanation:

<u>Domain of functions</u>

Some functions have restricted values of the independent variable x. It can be due to mathematical restrictions, like dividing by 0 or taking the square root of a negative number, of it can be due to practical conditions of the situation being modeled.

In this case, the area of a rectangle is given by the quadratic function.

A=50W - W^2

Since the area of a rectangle cannot be negative (and should be positive, though it could be zero), the practical domain of A is determined when

50W - W^2\geq 0

Taking common factor W

W(50 - W)\geq 0

Since W must be positive W>0

50 - W\geq 0

Or equivalently

50 \geq W

W \leq 50

The total interval is

0 < W

Correct option: A

Please note: The real restriction should be

0 < W\leq 50

if we allowed the area to be positive, but I'm providing the most possible correct available option

kifflom [539]

Answer: The system will succeed when the first alarm rings or when the first one fails, but the second one rings. The probability of this is 0.98

The probability of system failure is 1-(probability of success)= 1-0.98= 0.02

IgorC [24]

Answer:

Overall, if it is a major you can do well and enjoy yourself in, yes, statistics is a great major. Combine it with other majors like finance or economics or research-oriented disciplines like psychology, it'll be really good training for you. If you can't do it, do a minor. If you can't, take some electives.
