The property states that when two vectors a and b are multiplied together, the result is equal to the negative of b multiplied by a. This can be shown by multiplying the components of both vectors and then multiplying the result by -1.

a×b = (a2*b3 - a3*b2, a3*b1 - a1*b3, a1*b2 - a2*b1)

= (a2*b3 - a3*b2, a3*b1 - a1*b3, a1*b2 - a2*b1)

= (−1) * (a2*b3 - a3*b2, a3*b1 - a1*b3, a1*b2 - a2*b1)

= (−1) * (b2*a3 - b3*a2, b3*a1 - b1*a3, b1*a2 - b2*a1)

= − b × a.

The property a × b = − b × a states that when two vectors a and b are multiplied, the result is equal to the negative of b multiplied by a. This can be proven by first expanding the components of both vectors. For a vector a=(a1,a2,a3) and b=(b1,b2,b3), the expanded form of a×b is (a2*b3 - a3*b2, a3*b1 - a1*b3, a1*b2 - a2*b1). This can then be multiplied by -1 to get the expanded form of -b×a, which is (b2*a3 - b3*a2, b3*a1 - b1*a3, b1*a2 - b2*a1). Since this is equal to the original form of a×b, this proves the property.

Two figures are similar if their corresponding sides are in proportion and their corresponding angles are equal. In this case, Figure A and Figure B are similar, with a similarity ratio of r.

a. The ratio of the perimeters of similar figures is equal to the ratio of their corresponding sides. Since Figure A and Figure B are similar with a ratio of r, the ratio of their perimeters is also r.

b. If the perimeter of Figure A is p and the linear scale factor is r, the perimeter of Figure B can be found by multiplying the perimeter of Figure A by the linear scale factor:

Perimeter of Figure B = p * r

c. The area of similar figures is equal to the square of the linear scale factor multiplied by the area of the original figure. So, if the area of Figure A is a and the linear scale factor is r, the area of Figure B can be calculated as:

Area of Figure B = a * r^2

These formulas can be used to find the ratios and calculate the perimeters and areas of similar figures. Make sure to substitute the appropriate values given in the problem to find the specific answers.

Median of the probability distribution is 1.

Correct option is B.

The median of a set of data is the middlemost number or center value in the set. The median is also the number that is halfway into the set.

The median for a random variable X is m such that P(X≤m)≥1/2 and P(X≥m)≥1/2.

Given,

The probability distribution for the number of events in which a student competes is provided.

There are 7 degrees of freedom for the pooled-variance t-test.

To perform a pooled-variance t-test, we need to calculate the degrees of freedom. The formula for degrees of freedom in a pooled-variance t-test is:

\(\[\text{{df}} = n_1 + n_2 - 2\]\)

where \(\(n_1\)\) and \(\(n_2\)\) are the sample sizes of the two independent samples.

In this case, \(\(n_1 = 4\)\) and \(\(n_2 = 5\)\). Substituting these values into the formula, we get:

\(\[\text{{df}} = 4 + 5 - 2 = 7\]\)

In a pooled-variance t-test, we combine the sample variances from two independent samples to estimate the population variance. The degrees of freedom for this test are calculated using the formula \(df = n1 + n2 - 2\), where \(n_1\)and \(n_2\) are the sample sizes of the two independent samples.

To understand why the formula is \(df = n1 + n2 - 2\), we need to consider the concept of degrees of freedom. Degrees of freedom represent the number of independent pieces of information available to estimate a parameter. In the case of a pooled-variance t-test, we subtract 2 from the total sample sizes because we use two sample means to estimate the population means, thereby reducing the degrees of freedom by 2.

In this specific case, the sample sizes are \(n1 = 4\) and \(n2 = 5\). Plugging these values into the formula gives us \(df = 4 + 5 - 2 = 7\). Hence, there are 7 degrees of freedom for the pooled-variance t-test.

Therefore, there are 7 degrees of freedom for the pooled-variance t-test.

In a nonexperimental method, relationships between variables are studied by making observations or measures of the variables of interest.

Research without either the manipulation of an independent variable, the random assignment of individuals to conditions or orders of conditions, or both, is referred to as non-experimental research.

The non-experimental study is entirely dependent on variables that the researcher has no control over. By whatever means, they cannot manipulate, control, or change the subjects. Thus, all they can do is continue their research while monitoring and interpreting their subjects.

It is safe to assume that a non-experimental research design is used when there is no specific cause-effect study problem and the researcher simply wants to grasp a topic in depth without constraining it with variables. They examine the natural phenomena as they take place.

Therefore, in a nonexperimental method, relationships between variables are studied by observing or measuring the variables of interest.

The cost per kg of the mixture, obtained by combining 6kg of cane molasses and 12kg of beet molasses, is $2/kg.

To find the cost per kg of the mixture, we first calculate the total cost of the cane molasses and the beet molasses. The cane molasses costs $4 per kg, so the total cost of 6kg of cane molasses is 6kg * $4/kg = $24.

Similarly, the beet molasses costs $1 per kg, so the total cost of 12kg of beet molasses is 12kg * $1/kg = $12.

Next, we add the total costs of the two types of molasses together: $24 + $12 = $36.

To find the cost per kg of the mixture, we divide the total cost by the total weight of the mixture: $36 / (6kg + 12kg) = $36 / 18kg = $2/kg.

Therefore, the cost per kg of the mixture, obtained by combining 6kg of cane molasses and 12kg of beet molasses, is $2/kg.

Step-by-step explanation:

The bookshelf can hold 360 books with thickness 2cm, which is equal to 20 mm. Therefore the total space in mm that can be fit into the bookshelf is 360 * 20 = 7200 mm. To find the amount of books with thickness of 6 mm we can fit, we must divide 7200 by 6. The result is 1200

Answer:

0 ≤ t ≤ 18

Step-by-step explanation:

The cost of renting the boat without any discount is $8 per hour. However, Leila has a discount coupon for $3 off, so the effective cost per hour would be $8 - $3 = $5.

Let's assume Leila rents the boat for t hours. The total cost of renting the boat for t hours would be $5 multiplied by t, which is 5t.

According to the problem, Leila wants to spend at most $93. Therefore, we can set up the following inequality:

5t ≤ 93

This inequality represents the condition that the total cost of renting the boat (5t) should be less than or equal to $93.

Simplifying the inequality:

5t ≤ 93

Dividing both sides by 5 (since the coefficient of t is 5):

t ≤ 93/5

t ≤ 18.6

Since we cannot rent the boat for a fraction of an hour, we can round down the decimal value to the nearest whole number:

t ≤ 18

0 ≤ t ≤ 18

Answer: 0≤t≤12

Step-by-step explanation:

(I’m not sure if it’s 5 dollars off per hour, or total, but here’s what I did!)

If Leila has a $3 coupon, than she can spend +$3 because when you get a coupon, you can spend more, so 93+3 is equal to 96, now we just divide by 8 (because a boat costs $8 per hour) and we get 96/8=12.

Then, in inequality form it’s t≤12, because she can rent the boat for at most 12 hours, you could also do 0≤t≤12, because you can’t rent it for a negative amount of time, but either works.
