Select the equation that most accurately depicts the word problem. A class of 19 pupils has five more girls than boys. Let n = the number of boys. n + (n + 19) = 5 n + (n + 5) = 19 n - (n + 5) = 19 n + (n - 19) = 5

Answers

Answer 1

Answer:

Answer: $n+(n+5)=19$

Step-by-step explanation:

Given: The total number of students in a class = 19

Let n represents the number of boys.

Then, According to the question the number of girls = n+5

Now, the equation that most accurately depicts the given word problem will be :-

$\text{Girls+Boys=Total}\n\n\Rightarrow n+(n+5)=19$

Hence, the $n+(n+5)=19$ is the equation that most accurately depicts the given word problem .

Answer 2

Answer: n+(n + 5) = 19 should be the answer, if it is wrong then sorry..

n+ (n+ 5) = 19 is the best answer because they're are 19 people in the class so the total would be 19, now there is 5 more girls than boys and "n" represents the number of boys so you would put n + 5 = 19. You wouldn't subtract, you would add.

72/100 in simplest form

Answers

the answer is 31/50 (just half both sides)

In fractional simplest form we would begin by dividing both by 2 (always start this way, it's easier).

72/2 = 36
100/2 = 50

Now, we have 36/50 which could also be divided by 2.

36/2 = 18
50/2 = 25

Now, we have 18/25. From here, you would look to see if either number can be simplified using a common factor. With these numbers, nothing could be further simplified, so it would stay this way. :)

A group of Physicians must build an addition to their existing private clinic. They are considering three different sized additions; a small addition, a medium addition and a large addition. If the medical demand is high (there is a favorable market for the addition) they would realize a net profit of $100,000 with a large addition, a net profit of $40,000 with a medium addition and a net profit of $10,000 with a small addition. If the medical demand is low (there is an unfavorable market for the addition) they would realize a net loss of $40,000 with the large addition, a net loss of $10,000 with the medium addition and a net profit of $5,000 with the small addition. The Physicians were also able to assign the following utility preference values to each of the potential payoffs they could encounter. Utility of $100,000 is 1.0, U ($40,000) is 0.9, U ($10,000) is 0.6, U ($5,000) is 0.5, U ($-10,000) is 0.4, and U ($-40,000) is 0.0. The physicians also have a reliable forecast indicating a 40% probability of the high medical demand. Using expected monetary value theory, what should they do and what is the expected value of that decision? Using expected utility theory, what should they do and what is the expected utility of that decision?

Therefore , the solution of the given problem of probability comes out to be the medium addition because it has the greatest expected utility (0.72).

What is probability, exactly?

The primary goal of the structures within a methodology expression known as criteria is to provide an indication of the probability that the assertion is true or that a specific event will occur. Any number between zero and one, at which 0 is frequently indicated as a possibility and 1 has frequently used to denote a level of confidence, can be used to represent chance. The chance that a specific event will occur is displayed in a probability diagram.

Here,

The following formula can be used to determine each option's anticipated financial value:

=> EMV of big addition = (0.4 * $100,000) plus (0.6 * -$40,000) for a total of $16,000.

=> EMV of the middle addition is

= (0.4 * $40,000) plus (0.6 * -$10,000) for a total of $14,000.

=> EMV of a minor addition = (0.4 * 10,000) plus (0.6 * 5,000), which equals $6,000

The large addition should be chosen by the physicians as it has the greatest expected financial value of $16,000.

dividing each outcome's usefulness value by its likelihood, then adding the results:

=> (0.4 * 1.0) + (0.6 * 0.0) = 0.4 is the EU of the big addition.

=> (0.4 * 0.9) + (0.6 * 0.6) = 0.72 is the EU of medium addition.

Smaller EU = (0.4 * 0.5) + (0.6 * 0.6) = 0.58

The doctors should choose the medium addition because it has the greatest expected utility (0.72), according to expected utility theory.

1.)What is the only solution of 2x^2 + 8x = x^2 – 16?

Answers

If you would like to solve the equation 2 * x^2 + 8 * x = x^2 - 16, you can calculate this using the following steps:

2 * x^2 + 8 * x = x^2 - 16
2 * x^2 - x^2 + 8 * x + 16 = 0
x^2 + 8 * x + 16 = 0
(x + 4) * (x + 4) = 0
x = - 4

The correct result would be x = - 4.

Answer:

x= -4
