Answer:

Multiply the denominator of the fractional part by the whole number, and add the result to the numerator.

Step-by-step explanation:

You can add or subtract mixed numbers by turning them to improper fractions first. Improper fractions are fractions where the numerator is greater than the denominator.

The quotient of (2m + 4)/(m + 2) is 2.

The quotient of (2m + 4)/(m + 2) is 2. This can be simplified as follows:

Starting with the numerator: 2m + 4

And the denominator: m + 2

We can simplify the numerator by combining like terms: 2m + 4 = 2m + 2 + 2 = 2(m + 2)

So the expression becomes: 2(m + 2)/(m + 2)

Now, since the numerator and denominator have the same value, the expression simplifies to 2.

The reasonableness of assuming equal standard deviations depends on factors such as sample size, data distribution, and prior knowledge. It is important to assess these factors and make an informed decision based on the specific context and characteristics of the data being analyzed.

To determine whether it is reasonable to assume equal standard deviations when analyzing the data, we need to consider the nature of the data and the underlying assumptions of the statistical analysis method being used.

Assuming equal standard deviations means that we are assuming that the variability of the data is the same across all groups or populations being compared. This assumption is often made in statistical analyses such as analysis of variance (ANOVA) or t-tests when comparing means between groups.

Whether it is reasonable to assume equal standard deviations depends on the specific context and characteristics of the data. Here are a few factors to consider:

Sample size: If the sample sizes for each group or population being compared are similar, it may be more reasonable to assume equal standard deviations. Larger sample sizes provide more reliable estimates of the standard deviation and can help ensure that the assumption is met.

Similarity of data distribution: If the data in each group or population exhibit similar distributions and variability, assuming equal standard deviations may be reasonable. However, if the data distributions are visibly different or have varying levels of variability, assuming equal standard deviations may not be appropriate.

Prior knowledge or research: If there is prior knowledge or research suggesting that the standard deviations are likely to be equal across groups, it may be reasonable to make this assumption. However, if there is prior information indicating unequal standard deviations, it would be more appropriate to consider unequal standard deviations in the analysis.

Seema left 6/11 of the book for reading over the weekend.

To calculate the part of the book left for reading during the weekend, we need to subtract the part of the book Seema read during the weekday from the total book.

If Seema reads 5/11 of the book during the weekday, then:

This means 6/11 of the book is left for reading during the weekend. It is important to note that the fraction of the book read during the weekday and the fraction left for reading during the weekend add up to the total book. This means that 11/11 of the book will be read by Seema in total.

Answer:

g(x) = | x + 5 | + 2

Step-by-step explanation:

given f(x) then f(x ± h ) represents a horizontal translation of f(x)

• if x > 0 then a shift to the left of h units

• if x < 0 then a shift to the right of h units

here f(x) is shifted left by 5 units , then

g(x) = | x + 5 |

given f(x) then f(x) + k represents a vertical translation of f(x)

• if k > 0 then a shift up of k units

• if k < 0 then a shift down of k units

here f(x) is shifted up 2 units , then

g(x) = | x + 5 | + 2

The vectors (1, 0) and (0, 1) are in R(A). The vector (2, 2) is not in R(A). The vector x = (-1, 1) satisfies Ax = (1, 0). The vector x = (1, -1) satisfies Ax = (0, 1). There is no vector x such that Ax = (2, 2).The vector (1, 0) can be written as a linear combination of the columns of A .

To determine whether a vector b is in R(A), we can solve the equation Ax = b. If there exists a vector x such that Ax = b, then b is in R(A). If there does not exist a vector x such that Ax = b, then b is not in R(A).In this case, we can solve the equations Ax = (1, 0) and Ax = (0, 1) to find the vectors x = (-1, 1) and x = (1, -1), respectively. These vectors satisfy Ax = b, so (1, 0) and (0, 1) are in R(A).We cannot solve the equation Ax = (2, 2) for any vector x. This means that (2, 2) is not in R(A).Finally, we can write (1, 0) and (0, 1) as linear combinations of the columns of A as shown above. Since (2, 2) is not in R(A), it cannot be written as a linear combination of the columns of A.

The 2-transformation of K(1/2)^k cos(pi/2) is K(1/2)^(k/2) cos(pi/4).

To find the 2-transformation of the given expression, we need to substitute k/2 for k in the original expression.

Original expression: K(1/2)^k cos(pi/2)

Substituting k/2 for k: K(1/2)^(k/2) cos(pi/2)

Since cos(pi/2) equals 0, the expression simplifies to:

K(1/2)^(k/2) * 0

which is equal to 0.

Therefore, the 2-transformation of K(1/2)^k cos(pi/2) is K(1/2)^(k/2) cos(pi/4), and it converges to 0.

Convergence Region:

The convergence region of the 2-transformation K(1/2)^(k/2) cos(pi/4) is determined by the convergence region of the original expression K(1/2)^k cos(pi/2).

For the original expression to converge, the absolute value of (1/2)^k should be less than 1, and cos(pi/2) should not be equal to 0. Since cos(pi/2) equals 0, the original expression does not converge.

Therefore, the 2-transformation K(1/2)^(k/2) cos(pi/4) does not have a convergence region.

Poppy's sister used approximately 3.14 inches more wire per wall hanging than Poppy.

To find the amount of wire used by both Poppy and her sister, we'll calculate the circumference of their respective wall hangings using the formula:

C = 2πr

Since the diameter is twice the radius, we can find her sister's radius as follows:

Poppy's radius = 6.25 inches

Poppy's diameter = 2 * 6.25 = 12.5 inches

Sister's diameter = Poppy's diameter + 1 = 12.5 + 1 = 13.5 inches

Sister's radius = 13.5 / 2 = 6.75 inches

Now, we'll calculate the circumferences using the given value for π:

Poppy's circumference = 2 x 3.14 x 6.25 ≈ 39.25 inches

Sister's circumference = 2 x 3.14 x 6.75 ≈ 42.39 inches

Difference = Sister's circumference - Poppy's circumference

Difference = 42.39 - 39.25 = 3.14 inches

The simplified expression is 2 raised to the power of 7/10 multiplied by 3/7, where 'a' is equal to 7/10 and 'b' is equal to 1/7.

The given expression is (24) raised to the power of 3/2 minus (1/7) multiplied by 2 raised to the power of -3/5 multiplied by 2/5. To simplify, we expand the brackets and apply the power of the power property. The result is 2 raised to the power of 3, multiplied by 3/2, multiplied by 1/7, all to the power of -2, and then multiplied by 3/5 to the power of 2/5. Next, we multiply the bases and add the exponents, resulting in 2 raised to the power of (3/2 - 2 + 3/5, 2/5), multiplied by 3/7. Finally, we simplify the exponent to 7/10 and the expression becomes 2 raised to the power of 7/10, multiplied by 3/7. The values for 'a' and 'b' are a = 7/10 and b = 1/7.

A good method for evaluating the integral ∫2 to -√27 involves using the fundamental theorem of calculus and applying techniques of integral calculus.

Here's an explanation of the steps involved:

1. Start by determining the antiderivative of the integrand. In this case, the integrand is not specified, so let's assume it as f(x).

2. Apply the fundamental theorem of calculus, which states that if F(x) is the antiderivative of f(x), then ∫[a, b] f(x) dx = F(b) - F(a).

3. Find the antiderivative F(x) of f(x). This step can be challenging depending on the specific integrand. If the integrand has a known antiderivative, such as a polynomial or trigonometric function, then you can use the appropriate integration techniques.

4. Evaluate F(x) at the upper and lower limits of integration, which are 2 and -√27, respectively. Plug in these values into F(x) and subtract F(2) from F(-√27).

5. Simplify the expression obtained in step 4 to obtain the final result.

It's important to note that without the specific form of the integrand, it's not possible to provide an exact solution or determine the integral's numerical value. The above steps outline a general approach to evaluating integrals using the fundamental theorem of calculus and integration techniques. However, the specific method for evaluating the integral will depend on the nature of the integrand.

The set of equations that is enough information to prove that lines c and d are parallel lines cut by transversal p is option (c) m∠2 = 99° and m∠4 = 99°

The set of equations that is enough information to prove that lines c and d are parallel lines cut by transversal p is m∠2 = 99° and m∠4 = 99°.

To prove that lines c and d are parallel, we need to show that the alternate interior angles are congruent. Angle 2 and angle 4 are alternate interior angles, and if they are congruent, then lines c and d are parallel.

We are given that m∠2 = 99° and m∠4 = 99°, which means that angle 2 and angle 4 have the same measure. Therefore, we can conclude that lines c and d are parallel lines cut by transversal p.

The other sets of equations do not provide enough information to prove that lines c and d are parallel. The information given in the other sets of equations may be useful in other types of geometric proofs, but not in this case.

Therefore, the correct option is (c) m∠2 = 99° and m∠4 = 99°

Of the two points offered, only (2, -4) is a solution.

The given quadratic equation gives the parameters of the shape of the

graph of the equation.

Reasons:

The given function is n(t) = -2.82·t² + 25.74·t + 60.87

by analyzing the above function, we have;

At t = 0

n(0) = -2.82 × 0² + 25.74 × 0 + 60.87 = 60.87

Which gives;

\(\displaystyle t = -\frac{25.74}{2 \times (-2.82)} \approx 4.564\)

The maximum value of the function is therefore;

n(4.564) = -2.82 × 4.564² + 25.74 × 4.564 + 60.87 ≈ 119.61

The characteristics of the equation are;

Initial value of equation = 60.87
