Which statement describes how the reasonable domain<br> compares to the mathematical domain?

tigry1 [53]

A statement which best describes how the reasonable domain compares to the mathematical domain is that: C. the mathematical domain includes all real numbers, while the reasonable domain includes only real numbers greater than 2.

<h3>What is a domain?</h3>

In Mathematics, a domain can be defined as the set of all real numbers for which a particular function is defined. This ultimately implies that, a domain is the set of all possible input numerical values or numbers to a function and the domain of any graph comprises all the input numerical values or numbers which are primarily shown on the x-axis.

Next, we would evaluate the function which represents the perimeter of this rectangle by substituting the value of 2 as follows:

f(w) = 6w – 8

f(2) = 6(2) – 8

f(2) = 12 – 8

f(2) = 4.

For the length of this rectangle, we have:

Length = 2w - 4

Length = 2(2) - 4

Length = 4 - 4

Length = 0

Therefore, the width of this rectangle must be real numbers that are greater than 2.

Complete Question:

A rectangle has a length that is equal to 4 less than twice the width. The function for the perimeter depending on the width can be expressed with the function f(w) = 6w – 8, where w is the width of the rectangle in centimeters.

Which statement describes how the reasonable domain compares to the mathematical domain?

Both the mathematical and reasonable domains include only positive real numbers.

Both the mathematical and reasonable domains include only positive whole numbers.

The mathematical domain includes all real numbers, while the reasonable domain includes only real numbers greater than 2.

The mathematical domain includes all real numbers, while the reasonable domain includes only whole numbers greater than 2.

Which equals cos A to the nearest hundredth?

rusak2 [61]

Answer:

cosA ≈ 0.55

Step-by-step explanation:

cosA = $\frac{adjacent}{hypotenuse}$ = $\frac{AC}{AB}$ = $\frac{6}{11}$ ≈ 0.55 ( to the nearest hundredth )

Two methods, A and B, are available for teaching a certain industrial skill. The failure rate is 15% for A and 5% for B. However

baherus [9]

Answer:

P(A | F) = 81.81%

There is 81.81% probability that worker was taught by method A given that he failed to learn it correctly.

Step-by-step explanation:

The failure rate is 15% for A which means that

P(F | A) = 0.15

The failure rate is 5% for B which means that

P(F | B) = 0.05

Method B is more expensive and hence is used only 40% of the time which means that

P(B) = 0.40

Which means that A is used the other 60% of the time

P(A) = 0.60

A worker is taught the skill by one of the methods but fails to learn it correctly.

We are asked to find the the probability that he was taught by method A.

So that means we want to find out

P(A | F) = ?

We know that according to Baye's rule,

$P(A \:|\: F) = \frac{P(F \:|\: A)\times P(A) }{P(F \:|\: A)\times P(A) + P(F \:|\: B)\times P(B) }$

Substitute the given probabilities into the above equation

$P(A \:|\: F) = \frac{0.15\times 0.60 }{0.15\times 0.60 + 0.05\times 0.40}\\\\P(A \:|\: F) = \frac{0.09 }{0.09 + 0.02}\\\\P(A \:|\: F) = 0.8181 \\\\P(A \:|\: F) = 81.81\%$

Therefore, there is 81.81% probability that worker was taught by method A given that he failed to learn it correctly.
