If I understand your question correctly, pure water is 0% alcohol, so by adding water, this will dilute your 15% alcohol solution and lower the percentage of alcohol in the solution.

Many word problems are set up like "You have some amount of 15% alcohol solution and you add some pure water.  You end up with some other amount of the diluted mixture.  How much 15% alcohol solution and how much pure water were mixed."  

For those ones, use 0% alcohol for your pure water.

Answer:

John must score 286 on his 8th game to achieve an average score of 215.

What is an Average?

Average, also known as the mean, is a mathematical concept that represents the central value of a set of numbers. It is found by dividing the sum of the numbers by the total count of the numbers.

To find out what John must score on his 8th game to achieve an average score of 215, we need to use the formula for calculating the average or mean:

Average = (Sum of Scores) / (Number of Scores)

We can use this formula to solve for the unknown score:

215 = (159 + 182 + 225 + 240 + 198 + 200 + 230 + x) / 8

Multiplying both sides by 8, we get:

1720 = 159 + 182 + 225 + 240 + 198 + 200 + 230 + x

Simplifying, we get:

1720 = 1434 + x

Subtracting 1434 from both sides, we get:

x = 286

Therefore, John must score 286 on his 8th game to achieve an average score of 215.

This equation has two solutions: λ = 0 and λ = -1

The determinant of a matrix is given by the formula:

det(A) = a11(a22a33 - a23a32) - a12(a21a33 - a23a31) + a13(a21a32 - a22a31)

In the given matrix, the values of a11, a22, and a33 are λ, (λ+1), and λ respectively. The values of a12, a13, a21, a23, a31, and a32 are all 0. Substituting these values into the formula for the determinant gives:

det(A) = λ((λ+1)λ - 0) - 0(0 - 0) + 0(0 - 0) = λ^3 + λ^2

To find the values of λ for which the determinant is zero, we can set the determinant equal to zero and solve for λ:

λ^3 + λ^2 = 0
λ^2(λ + 1) = 0

This equation has two solutions: λ = 0 and λ = -1. Therefore, the values of λ for which the determinant is zero are 0 and -1. The answer can be written as a comma-separated list as follows:

The number is 30.

Addition is one of the basic mathematical operations where two or more numbers is added to get a bigger number.

The process of doing addition is also called as finding the sum

Given that,

The sum of the digits of a certain two-digit number is 3.

Since it is a two digit number, there will be a tens place and a ones place.

Let x be the digit in tens place and y be the digit in ones place.

x + y = 3

The number can also be written as 10x + y, since x is in the tens place.

When the number is reversed, tens place changed to ones place and vice versa.

The reversed number is 10y + x.

Given that the value of the number is decreased by 27 when the digits is reversed.

Original number - 27 = Reversed number

10x + y - 27 = 10y + x

9x - 9y = 27

x - y = 3

Also, we have,

x + y = 3  [Equation 1]

x - y = 3   [Equation 2]

Adding the equations,

2x = 6

x = 6/2 = 3

Substituting in equation 1, y = 0

The rational expression (2x-3)/((2x-3) (2x-3)) satisfies the given constraints.

To create a rational expression with the given constraints, we need to have a binomial in the numerator that cancels out with a binomial in the denominator to produce the desired expression, (1)/(2x-3).

One way to do this is to multiply the desired expression by a binomial that is the same as the one in the denominator. This will give us a rational expression with the desired constraints.

For example, we can multiply (1)/(2x-3) by (2x-3)/(2x-3) to get:

(1 * (2x-3))/((2x-3) * (2x-3))

Simplifying the numerator and denominator gives us:

Answer:

g(x) = f(x + 2) = 2^(x + 2) + 2

Step-by-step explanation:

To shift the function f(x) = 2^x + 2 two units to the left, we need to replace x with (x + 2) in the equation. This will shift the graph horizontally to the left by two units.

So, the new function g(x) that represents the shifted graph is:

g(x) = f(x + 2) = 2^(x + 2) + 2

    Since the first equation uses a ≤ symbol, we know we will use a solid line. This is because it is less than and equal to. Then, we will graph it as a regular slope-intercept line.

    This line has a slope of 5 and a y-intercept of -2. This means we will start at (0, -2) and move five units up for every unit right, or five units down for every unit left.

    For the next equation, it uses a > symbol so we will use a dashed line. This is because it is not equal to, only greater than. Same as the previous. We will graph it as a slope-intercept line, but using a dashed line instead of a solid line.

    This line has a slope of -2 and a y-intercept of positive 5. This means we will start at (0, 5) and move two units down for every unit right, or two units up for every unit left.

This function rule represents the original function f(x) = √x, shifted up 5 units, vertically stretched by a factor of 2, and shifted to the right 3 units.

The function rule for g(x) from f(x) = √x can be found by applying the given transformations to f(x). First, we shift up 5 units by adding 5 to the function. Then, we apply a vertical stretch by a factor of 2 by multiplying the function by 2. Finally, we shift to the right 3 units by replacing x with (x - 3) in the function. The resulting function rule for g(x) is:

g(x) = 2√(x - 3) + 5

This function rule represents the original function f(x) = √x, shifted up 5 units, vertically stretched by a factor of 2, and shifted to the right 3 units.

The baker makes a total of 140 muffins on Monday.

The baker makes 18 blueberry muffins on Tuesday.

What are percentages?

Percentages are a way of expressing a fraction or proportion out of 100. The term "percent" literally means "per hundred." Percentages are commonly used in many areas of everyday life, including finance, science, and statistics.

To express a number as a percentage, it is multiplied by 100. For example, 0.75 is equivalent to 75 percent, since 0.75 x 100 = 75. Similarly, 50 percent is equivalent to 0.5 or 1/2.

Percentages are commonly used to express changes and comparisons. For example, if a product's price increases from $100 to $120, this represents a 20 percent increase in price. If a person scored 80 out of 100 on a test, this represents an 80 percent score.

Percentages are also used to calculate percentages of a total. For example, if a person earned $40,000 out of a total company income of $500,000, their income represents 8 percent of the total income. Similarly, if a person wants to calculate a 20 percent tip on a $50 meal, they would calculate 20 percent of $50, which is $10.

In summary, percentages are a way of expressing a fraction or proportion out of 100, and are commonly used to express changes, comparisons, and percentages of a total in everyday life.

A. Let's assume the total number of muffins the baker makes on Monday to be x.

According to the problem, the number of blueberry muffins that the baker makes is 30% of the total number of muffins.

So, 30% of x is equal to 42:

0.30x = 42

To solve for x, we can divide both sides by 0.30:

x = 140

Therefore, the baker makes a total of 140 muffins on Monday.

B. Let b be the number of blueberry muffins the baker makes on Tuesday.

According to the problem, the number of blueberry muffins is still 30% of the total number of muffins. So, we can set up the equation:

0.30(60) = b

Simplifying the left side:

18 = b

Therefore, the baker makes 18 blueberry muffins on Tuesday.

Simplifying the left side:

The correct answer is c. Failed to reject the null hypothesis.

Failed to reject the null hypothesis.

Explanation:

In this problem, we are given the price of drugs for human doses and animal doses from different pharmacies. We are asked to form a statistical decision using the p-value method. The null hypothesis is that the prices for the animal doses are equal to the prices for the human doses, while the alternative hypothesis is that the prices for the animal doses are significantly less than the prices for the human doses.


To form a statistical decision, we need to compare the p-value with the level of significance (α). If the p-value is less than or equal to α, we reject the null hypothesis. If the p-value is greater than α, we fail to reject the null hypothesis.


In this case, the level of significance is 1% (α=0.01). Since the p-value is not given in the problem, we cannot make a decision. Therefore, the correct answer is c. Failed to reject the null hypothesis.
