The answer to the problem is b

Let's solve for x.

2x−9y=14

Step 1: Add 9y to both sides.

2x−9y+9y=14+9y

2x=9y+14

Step 2: Divide both sides by 2.

2x /2

= 9y+14 /2

x= 9 /2 y+7

We need to solve for x.

2x - 9y = 14

Move the 9y to the right side and use inverse operations.

2x = 14 + 9y

Divide both sides of the equation by 2.

x = 7 + 9/2y or x = 7 + 4.5y

Answer:

The answer is A.

15 + 4 + 3 = 15 + 7

A. 3

First, simplify the equation. (x means the same thing as the symbol)

19 + x = 22

Subtract 19 from both sides of the equation.

x = 22 - 19

x = 3

Answer:

4/663

Step-by-step explanation:

There are four queens.  The probability that the first card is a queen is 4/52.

There are four kings.  There are 51 cards left after the first card has been drawn, so the probability that the second card is a king is 4/51.

Therefore, the probability that the first card is a queen AND the second card is a king is:

P = 4/52 × 4/51

P = 4/663

The probability of drawing a queen first and a king second from a standard deck without replacement is 1/663.

The student is asking about the probability of drawing two specific cards from a standard deck of 52 cards. To calculate this probability, we need to consider the sequence of events without replacement. For the first card to be a queen, the probability P(A) is 4/52 because there are 4 queens in a deck of 52 cards. After drawing a queen, there are now 51 cards left in the deck. The chance that the second card is a king, P(B), is then 4/51, as there are still 4 kings but only 51 cards remaining.

The two events are dependent since the outcome of the first draw influences the second. Therefore, the combined probability of both events occurring is found by multiplying the probabilities of each event:

P(A and B) = P(A) × P(B) = (4/52) × (4/51)

This gives us P(A and B) = 1/13 × 1/51, which simplifies to 1/663.

Answer:

this is no picture or any thing to help me to give you a answer

Step-by-step explanation:

Answer:

I am sorry but you don't have a picture.

Step-by-step explanation:

P(B|A): P(A and B) / P(A)

P(A and B): P(A)•P(B) so 0.9 • 0.6 = 0.54

P(A|B): 0.54 / 0.9 = 0.6

Answer: D) 0.6

The value of the conditional probability is given by Bayes theorem and the value of P ( A | B ) = 0.1333

The likelihood that an event will occur based on the likelihood that a comparable outcome will occur in the future. The theorem offers a method for updating existing predictions or hypotheses in light of fresh or updated data. This is known as conditional probability.

Bayes Theorem states that based on past knowledge of circumstances that could be relevant to the occurrence, the Bayes Theorem estimates the likelihood of an event.

And , P ( A | B ) = [ P ( B | A ) P ( B ) ] / P ( A )

Given data ,

Let the conditional probability be represented as P

Now , the value of P ( A ) = 0.9

The value of P ( B ) = 0.6

The value of P ( B | A ) = 0.2

From the Bayes theorem , we get

P ( A | B ) = [ P ( B | A ) P ( B ) ] / P ( A )

On simplifying , we get

P ( A | B ) = [ 0.2 x 0.6 ] / 0.9

P ( A | B ) = 0.12 / 0.9

P ( A | B ) = 0.1333

Hence , the Bayes theorem is solved

Answer:

By 0.75

Step-by-step explanation:

From the stem-and-leaf plot you can find James's scores:

79, 81, 83, 83, 83, 85, 85, 88, 94, 99.

The mode is 83 (most often score). If he drops his scores from the first two weeks, his mode score increases by 2. This means that the mode became 85 and the data looks like

79, 81, 83, 85, 85, 88, 94, 99.

Now find two means.

1. The old mean:

[tex]\dfrac{79+81+83+83+83+85+85+88+94+99}{10}=\dfrac{860}{10}=86;[/tex]

2. The new mean:

[tex]\dfrac{79+81+83+85+85+88+94+99}{8}=\dfrac{694}{8}=86.75;[/tex]

Thus, the mean will increase by 0.75.

Answer:

C. an irregular concave heptagon

Explanation:

Before we begin, we should define the terms used in the choices given:

1- Heptagon: It is the polygon that has 7 sides

2- Regular heptagon: It is a 7-sided polygon in which all sides are equal and all angles are equal

3- Irregular heptagon: It is a 7-sided polygon in which neither the sides nor the angles are equal

4- Concave heptagon: It is a 7-sided polygon in which one or more of its angles are more than 180°

5- Convex heptagon: It is a 7-sided polygon in which all its angles are less than 180°

6- Complex heptagon: It is a 7-sided polygon whose dimensions are in the complex plane

Now, let's check the given diagram:

It is a 7-sided polygon, therefore, it is a heptagon

It's sides as well as its angles are not equal, therefore, it is an irregular heptagon

It has interior angles measuring more than 180°, therefore, it is a concave heptagon

Its dimensions are not in the complex plane, therefore, it is not a complex polygon

Based on the above, the best choice is:

C. an irregular concave heptagon

Hope this helps :)

A heptagon is a seven-sided polygon. Regular heptagons have all equal sides and angles, irregular convex heptagons have unequal sides but all angles less than 180 degrees, irregular concave heptagons have at least one interior angle more than 180 degrees while complex heptagons have intersecting sides.

In mathematics, a heptagon is a seven-sided polygon. A- A regular heptagon is a heptagon in which all seven sides and all seven angles are congruent, meaning they are of equal length or degree. B- An irregular convex heptagon has seven sides, but they are not all equal, however, all its interior angles are less than 180 degrees. C- An irregular concave heptagon is also an irregular heptagon, but at least one of its interior angles is more than 180 degrees. D- A complex heptagon is a heptagon with sides that intersect each other, but this is not a standard classification in geometry.

Final answer:

Denise will need to pay $464.29 each month for 14 months to repay a $6500 loan and avoid any interest charge.

Explanation:

To calculate how much Denise will need to pay each month to avoid an interest charge on her $6500 loan, we simply divide the total loan amount by the number of months she has to repay the loan.

So, the monthly payment Denise needs to make is $6500 divided by 14 months:

$6500 ÷ 14 months = $464.29 per month (rounded to two decimal places).

To repay the full amount in 14 months and avoid any interest, Denise will need to pay $464.29 each month.

Answer:

x = 137

Step-by-step explanation:

∠43° and ∠x° are same side exterior angles as they are on the same side as the transversal but outside the parallel lines. The 2 angles are supplementary, hence

x + 43 = 180 ( subtract 43 from both sides )

x = 137

Based on the information given, the value of x will be 137°.

It should be noted that angles x and 43° are on the same side of the transversal but they're are outside the parallel lines. In this case, the angles are supplementary which means that when they are added together, their total angles equal 180°.

Therefore, the value of angle x will be:

= 180° - 43°

= 137°

Therefore, x is 137°.

Answer:

Step-by-step explanation:

To maximize profit, at $8125 prices should the school charge for the yearbooks

Simplify first the equation,

R(x) = 25000 - 2500x + 6250x - 625x²

Then, we differentiate the equation and equate to zero.

dR(x) = -2500 + 6250 - 1250x = 0

The value of x from the equation is 3.

(1) The price is equal to 50 - 5(3) = $35.

(2) The possible maximum revenue:

R(x) = 2500 - 2500(3) + 6250(3) - 625(3²) = $8125
