Answer: 0.49 yards

Step-by-step explanation: First, you do $15-$9.48 to find out how much she spent on the ribbon, which is $5.52. Then, you divide $5.52 by 12 (cents) to figure out how many yards Yolanda could buy with 5.52. 5.52/12=0.49 yards

Answer:

56

Step-by-step explanation:

98 gallons of a 20 percent salt solution results in 20/100 * 98 = 19.6 gallons of salt.

Let's say we need x gallons of the 42% salt solution.

To make sure that the resulting mixture has 28% salt, we need to have the total salt divided by the total amount of gallons.

We have 98 total gallons in the first solution, and x total gallons in the second solution. We have 19.6 gallons of salt in the first solution and 42% of x gallons in the second solution:

\(19.6+\frac{42}{100}(x)=\frac{28}{100}(98+x)\)

Expanding, we have

\(19.6+\frac{42}{100}x=27.44+\frac{28}{100}x\)

Subtracting 19.6 and subtracting 28/100x from both sides equals

\(\frac{14}{100}x=7.84\)

Multiplying both sides by 100:

\(14x=784\)

Dividing both sides by 14:

\(x=56\)

Answer:

3:25

Step-by-step explanation:

The photo shows how it's solved.

Answer: 3:25

Step-by-step explanation:

Step 1) Convert the decimal number to a fraction by making 0.12 the numerator and 1 the denominator

0.12 = 0.12/1

Step 2) Multiply the numerator and denominator by 100 to eliminate the decimal point.
0.12 x 100

------------ = 12/100
1 x 100

Step 3) Simplify the fraction in the previous step by dividing the numerator and the denominator by the greatest common factor (GCF) of 12 and 100. (The GCF of 12 and 100 is 4.)

12 ÷ 4

---------  = 3/25  

100 ÷ 4

Step 4) Convert the fraction in the previous step to a ratio by replacing the divider line with a colon like this:  

3  

25   =  3:25

Another point on the line is (-9, 7). Ultimately, the choice of which point to use depends on the context or specific requirements of the problem you are solving.

To determine which point to use from the equation y - 7 = 3(x + 9), we need more information.

The equation provided represents a linear equation in the form y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope.

Without additional context or specific instructions, we can choose any point that satisfies the equation to use as a reference.

For example, if we let x = 0, we can solve the equation for y:

y - 7 = 3(0 + 9)

y - 7 = 3(9)

y - 7 = 27

y = 27 + 7

y = 34

So, one point on the line is (0, 34).

Alternatively, if we let x = -9, we can solve the equation for y:

y - 7 = 3(-9 + 9)

y - 7 = 3(0)

y - 7 = 0

y = 7

So, another point on the line is (-9, 7).

Because I am right!

The magnitude of the vector sum (A + B) is approximately 4.974.

To find the magnitude of the vector sum (A + B), we need to add the corresponding components of vectors A and B and then calculate the magnitude of the resulting vector.

Given:

Vector A: (5.1, 0)

Vector B: (-2.6, -4.3)

To find the vector sum (A + B), we add the corresponding components:

(A + B) = (5.1 + (-2.6), 0 + (-4.3))

= (2.5, -4.3)

Now, let's calculate the magnitude of the vector (2.5, -4.3):

Magnitude = sqrt((2.5)^2 + (-4.3)^2)

= sqrt(6.25 + 18.49)

= sqrt(24.74)

≈ 4.974

The correct answer is B. The sample represents a proportion of the population.

A point estimate is a single value used to estimate a population's unknown parameter. The sample proportion (denoted by p), in the context of determining the population proportion, is a widely used point estimate. The sample proportion is determined by dividing the sample's success rate by the sample size.

The sample must be representative of the population for it to be a reliable point estimate of the population proportion. To accurately reflect the proportions of various groups or categories present in the population, the sample should be chosen at random.

An examination, a candidate has to score a minimum of 24 marks in order to clear the exam. the maximum that he can score is 40 marks.

The class will be as follows:

Class i: values<24 => invalid class

Class ii: 24 to 40  => valid class

Class iii: values> 40 => invalid class

We need to identify valid equivalence values. Valid equivalence values will be there in a valid equivalence class. All the values should be in class ii.

A probability is a ratio between the number of favorable events and the total number of events.

The total number of events that can happen is called the size of the sample space.

The number of favorable events cannot be greater than the total number of events, this is why, the probability will always be a number between 0 and 1.

Since 7.628 is not a number between 0 and 1, it cannot be a probability.

Answer:

x/16 + 10

Step-by-step explanation:

10+(x÷16)

To add or subtract expressions, expand them to make their denominators the same. Multiply 10 times 16/16.

10 x 16 / 16 + x/16

Since 10 x 16 / 16 and x/16 have the same denominator, add them by adding their numerators.

10 x 16 + x / 16

Do the multiplications in 10×16+x.

160 + x / 16 = x/16 + 10

BD= 2 x 1

CA= 1 x 2

BC= 2 x 3

Step-by-step explanation:

The dimensions of the matrices BD, CA, and BC are,

2×2, 2×1, and 2×3 respectively.

Suppose we have two matrices \(A_{(m)\times(n)}\) and \(B_{(p)\times(q)}\) their multiplication is possible only when the no. of columns in the first matrix is equal to the no. of rows in the second matrix.

which is n = p and the resultant matrix will AB will have dimensions \(AB_{(m)\times(q)}\).

Given B is a 2 cross 2 matrix and D is a 2 cross 1 matrix, so the no. of columns in B is 2, and the no. of rows in matrix D is 2 so they are eligible for matrix multiplication and their resultant BD will have a dimension 2 cross 2.

Similarly, the CA matrix will have a dimension of 2 cross 1.

And, the BC matrix will have dimensions 2 cross 3.

Answer:

Fail to reject the null hypothesis because the p-value =0.10 is more than the significance level α=0.05.

Step-by-step explanation:

The significant level for this case study is 5% - 0.05. If the results gotten is less than the significance level, we reject the null hypothesis, but if greater, we fail to reject the null hypothesis.

In this case study, the p-value is 0.10 which is a lot higher than 0.05, thus we will fail to reject the null hypothesis because the p-value =0.10 is more than the significance level α=0.05.
