Julie bought 40 postcards and 100 stamps to spend a total of $51.40.. Solving the equation 26x + 41(2x + 20) = 5140 will give the quantities.

To find the number of postcards and stamps Julie bought, we set up the equation 26x + 41(2x + 20) = 5140, where x represents the number of postcards. By solving this equation, we can determine the value of x, which represents the number of postcards Julie bought.

Expanding the equation gives us 26x + 82x + 820 = 5140. Combining like terms, we have 108x + 820 = 5140. Subtracting 820 from both sides gives 108x = 4320. Dividing both sides by 108, we find x = 40.

Therefore, Julie bought 40 postcards. Substituting this value into the expression for stamps, we find the number of stamps is 2x + 20 = 2(40) + 20 = 100.

In conclusion, Julie bought 40 postcards and 100 stamps to spend a total of $51.40.

If a machine that works at a constant rate can fill 40 bottles of milk in 3 minutes, Then the machine will take approximately 18 minutes to fill 240 bottles.

Constant rate is a rate of change is constant when the ratio of the output to the input stays the same at any given point on the function.

Given that machine take 3 minutes to fill 40 bottles

So for 1 minute the machine fill \(\frac{40}{3}\) = 13.3333 bottles.

That is in 1 minute the machine fill approximately 14 bottles.

So the machine take a time to fill 240 bottles is \(\frac{240}{14} = 18.461\).

Thus the machine take approximately 18 minutes to fill 240 bottles.

Answer:

The slope-intercept form is y =  \(-\frac{3}{4}\) x + 8 ⇒ B

Step-by-step explanation:

The slope-intercept form of the linear equation is:

y = m x + b, where

From the given in the question

∵ The slope of the line is \(-\frac{3}{4}\)

∴ m =  \(-\frac{3}{4}\)

→ Substitute its value in the form of the equation above

∴ y =  \(-\frac{3}{4}\) x + b

→ To find b substitute x and y by the coordinates of any point on the line

∵ The line passes through the point (8, 2)

∴ x = 8 and y = 2

∵ 2 =  \(-\frac{3}{4}\) (8) + b

∴ 2 = -6 + b

→ Add 6 to both sides to find b

∴ 2 + 6 = -6 + 6 + b

∴ 8 = b

→ Substitute the value of b in the equation above

∴ y =  \(-\frac{3}{4}\) x + 8

∴ The slope-intercept form is y =  \(-\frac{3}{4}\) x + 8

Using the Bayes' theorem, we find the probability that the transferred ball was white given that the second ball drawn was white to be 52/89, or approximately 0.5843.

To solve this problem, we can use Bayes' theorem, which relates the conditional probability of an event A given an event B to the conditional probability of event B given event A:

P(A|B) = P(B|A) * P(A) / P(B)

where P(A|B) is the probability of event A given that event B has occurred, P(B|A) is the probability of event B given that event A has occurred, P(A) is the prior probability of event A, and P(B) is the prior probability of event B.

In this problem, we want to find the probability that the transferred ball was white (event A) given that the second ball drawn was white (event B). We can calculate this probability as follows:

P(A|B) = P(B|A) * P(A) / P(B)

P(B|A) is the probability of drawing a white ball from urn b given that the transferred ball was white and is now in urn b. Since there are now six white balls and three black balls in urn b, the probability of drawing a white ball is 6/9 = 2/3.

P(A) is the prior probability of the transferred ball being white, which is the number of white balls in urn a divided by the total number of balls in urn a, or 6/13.

P(B) is the prior probability of drawing a white ball from urn b, which can be calculated using the law of total probability:

P(B) = P(B|A) * P(A) + P(B|not A) * P(not A)

where P(B|not A) is the probability of drawing a white ball from urn b given that the transferred ball was black and P(not A) is the probability that the transferred ball was black, which is 7/13.

To calculate P(B|not A), we need to first calculate the probability of the transferred ball being black and then the probability of drawing a white ball from urn b given that the transferred ball was black.

The probability of the transferred ball being black is 7/13. Once the transferred ball is moved to urn b, there are now five white balls and four black balls in urn b, so the probability of drawing a white ball from urn b given that the transferred ball was black is 5/9.

Therefore, we can calculate P(B) as follows:

P(B) = P(B|A) * P(A) + P(B|not A) * P(not A)

= (2/3) * (6/13) + (5/9) * (7/13)

= 89/117

Now we can plug in all the values into Bayes' theorem to find P(A|B):

P(A|B) = P(B|A) * P(A) / P(B)

= (2/3) * (6/13) / (89/117)

= 52/89

Therefore, the probability that the transferred ball was white given that the second ball drawn was white is 52/89, or approximately 0.5843.

Yes, the sequence is geometric as it follows a pattern where each term is multiplied by a common ratio to get the next term. In this case, we can find the common ratio by dividing any term by its preceding term.

Let's choose the second and first terms:Common ratio = (second term) / (first term)= (-4) / (-2)= 2Now that we know the common ratio is 2, we can use it to find any term in the sequence. For example, to find the fourth term, we can multiply the third term (-16) by the common ratio:Fourth term = (third term) × (common ratio)= (-16) × (2)= -32Therefore, the fourth term of the sequence is -32. We can continue this pattern to find any other term in the sequence.

Answer:

Mango = 0.5, Peach = 1.75

Step-by-step explanation:

Let x represent the price of mango

Let y represent the price of peach

Melanie: 8x + 6y = 14.50

Jaya: 4x + 7y = 14.25

Isolate for a variable in one of the equations (just pick a random one, you don't have to pick mine)

4x + 7y = 14.25 => x = (14.25 - 7y)/4 = 3.5625 - 7/4y

Plug into other equation

8x + 6y = 14.50

8(3.5625 - 7/4y) + 6y = 14.5

28.5 - 14y + 6y = 14.5

28.5 - 14.5 = 14y - 6y

14 = 8y

y = 1.75

4x + 7y = 14.25

4x + 7(1.75) = 14.25

4x + 12.25 = 14.25

4x = 2

x = 0.5

Therefore , the solution of the given problem of arithmetic mean comes out to be  option A an=3+2(n-1).

The usual values of a list are determined by adding up every single integer one of the items on the list, which are frequently referred to as the organization's objectives. The number of list items with the highest abundance is then used to adjust these average values. Mathematical growth trends are similar. The number 21 turns into seven by adding three to the true means of the digits 5, 7, and 9, which is 4.

Here,

The following is the formula for the general word "an" in an arithmetic sequence:

=> a = a1 + (n - 1)d

where the first term is denoted by a1, the term number is n, and the common difference is d.

A1 = 3 and A11 = 23 are provided. To determine the common difference, we can use the method for the eleventh term:

=> a11 = a1 + (11 - 1)d

=> 23 = 3 + 10d

=>  d = 2

Inputting this number of d into the general term's formula yields the following results:

=> a = 3 + (n - 1)2

The right response is therefore: an=3+2(n-1).
