Step-by-step explanation:

[tex]x = 12\to y=12+6=18\\x=13\to y=13+6=19\\x=14\to y=14+6=20\\x=15\to y=15+6=21\\\vdots\\x\to y=x+6[/tex]

The linear function represented in the table is given by:

[tex]y = x + 6[/tex]

A linear function has the following format:

[tex]y = mx + b[/tex]

In which:

From the table, two of the points (x,y) are (12,18) and (13,19).

The slope is given by change in y divided by change in x, thus:

[tex]m = \frac{19 - 18}{13 - 12} = 1[/tex]

Then

[tex]y = x + b[/tex]

Point (12,18) means that when [tex]x = 12, y = 18[/tex], and this is used to find b.

[tex]y = x + b[/tex]

[tex]18 = 12 + b[/tex]

[tex]b = 6[/tex]

Thus, the equation is:

The degree of the term [tex]4xy^2z[/tex] is 4, calculated by summing up the exponents of all variables in the term.

Explanation:

The degree of a monomial like [tex]4xy^2z[/tex] is found by adding up the exponents of all the variables in the term. In this case, the exponent of x is 1, the exponent of y is 2, and the exponent of z is 1. Therefore, the degree of [tex]4xy^2z[/tex] is 1+2+1 = 4.

The degree of a polynomial is an important concept in algebra that tells you the highest degree of any term in the polynomial. For this reason, understanding how to calculate the degree of individual terms like 4xy^2z is crucial for working with polynomials. Remember, coefficients, like the number 4 in this expression, do not affect the degree of the term.

The degree of the term [tex]\(4xy^2z\)[/tex] is 4.

To find the degree of the term [tex]\(4xy^2z\)[/tex], we add up the exponents of all the variables present in the term.

In the term [tex]\(4xy^2z\)[/tex], we have:

- (x) with an exponent of 1,

- (y) with an exponent of 2,

- (z) with an exponent of 1.

Adding up the exponents:

[tex]\[1 + 2 + 1 = 4\][/tex]

So, the degree of the term [tex]\(4xy^2z\)[/tex] is 4.

For a set of data, the average squared deviation from the mean, with a denominator of n-1 is called the: Sample Variance.

Answer: Sample Variance

For a set of data, the average squared deviation from the mean, with a denominator of n-1 is called the sample variance.

Sample variance can be defined as the expectation of the squared difference of data points from the mean of the data set. It is an absolute measure of dispersion and is used to check the deviation of data points with respect to the data's average.

Suppose a data set is given as 3, 21, 98, 17, and 9. The mean (29.6) of the data set is determined. The mean is subtracted from each data point and the summation of the square of the resulting values is taken. This gives 6043.2. To get the sample variance, this number is divided by one less than the total number of observations. Thus, the sample variance is 1510.8.

Sample variance is used to measure the spread of the data points in a given data set around the mean. All observations of a group are known as the population. When the number of observations start increasing it becomes difficult to calculate the variance of the population. In such a situation, a certain number of observations are picked out that can be used to describe the entire group. This specific set of observations form a sample and the variance so calculated is the sample variance.

[tex]S^{2}= \frac{\sum_{i=1}^{n}(x_{i}-\mu )^{2} }{n-1}[/tex]

Hence, For a set of data, the average squared deviation from the mean, with a denominator of n-1 is called the sample variance.

Both Laura and Rob are correct in finding the decimal equivalent of a fraction.

A fraction is a mathematical expression representing a part of a whole. It consists of a numerator (top number) indicating the part being considered and a denominator (bottom number) representing the total number of equal parts. Fractions are used for division, ratios, and comparisons in mathematics.

To find the decimal equivalent of a fraction, you can use either method mentioned by Laura or Rob. Laura's method involves writing an equivalent fraction with 100 as the denominator and then dividing the numerator by the denominator. For example, 39/50 can be written as 78/100, which is equal to 0.78 as a decimal. Rob's method involves dividing the numerator (39) by the denominator (50) directly, which also gives you the decimal value of 0.78.

Answer:

Amanda = 22

Alisa = 26

Step-by-step explanation:

Amanda : Alisa = 11 : 13

Amanda : Alisa = 11x : 13x

Alisa gives 10 dresses to Amanda.

Amanda = 11x + 10

Alisa = 13x - 10

Amanda will have twice as many dresses as Alisa has.

11x + 10 = 2(13x - 10)

11x + 10 = 2(13x - 10)

11x + 10 = 26x - 20

15x = 30

x = 2

Amanda

= 11 x 2

= 22

Alisa

= 13 x 2

= 26

Amanda has 22 dresses, and Alisa has 26 dresses. This is calculated by solving the equations given in the problem according to the ratio and conditions provided. The number of dresses each girl has fits the criteria set by the original problem.

Solving the Ratio Problem

To find the number of dresses Amanda and Alisa have, we start by setting up the ratio and the conditions given:

Let the number of dresses Amanda has be 11x and the number Alisa has be 13x. The ratio of their dresses is 11:13.

If Alisa gives 10 dresses to Amanda, Amanda's dresses become 11x + 10 and Alisa's dresses become 13x - 10. According to the problem, Amanda will then have twice as many dresses as Alisa:

Answer:

10 sides, 114, for each interior angle, and 36 for each exterior angle.

Step-by-step explanation:

Since the sum of all exterior angle is 360 multiply by 4 which gets you 1140. Then we know that there are 8 sides to an octagon to find the sum of all the interior angles we can multiply the number of sides minus 2 by 180. Now knowing this we can do this for an octagon which gives us 1080. Since that is close to 1140 we can play around with the numbers and we will eventually go with the number 10 we minus this by 2 and multiply by 180 to get 1140. To find the measurement of 1 interior angle we would divide that number by the sides, so 1140 by 10 to get 114 for our 1 interior measurement. to get the 1 exterior measurement we would divide 360 by the number of sides which gives us 36 since the sum of all exterior measurements equals 360. I hope this helps.  

The polygon in question is an octagon, with eight sides. Each exterior angle measures 45° and each interior angle measures 135°. The calculation is based on the relationship between the sum of the interior and exterior angles of a polygon.

The question involves finding the number of sides of a polygon where the sum of all the interior angles is four times the sum of its exterior angles, and then calculating the measures of each exterior and interior angle. First, it is essential to note two key facts: the sum of exterior angles of any polygon is always 360°, and the formula for the sum of interior angles of a polygon is (n-2) × 180°, where 'n' is the number of sides of the polygon.

Given that the sum of the interior angles is four times the sum of the exterior angles, we can write the equation (n-2) × 180 = 4 × 360. Simplifying this equation will give us n = 8, indicating the polygon is an octagon. Each exterior angle of an octagon is equal to 360/n, which results in each exterior angle measuring 45°. Since interior and exterior angles are supplementary, each interior angle measures 135° (180° - 45°).

From the given picture, it can be seen that the given polygon is dividede into four right triangles of same measurement.

Consider triangle in the first quadrant, then the base of triangle = |a-0|=a

Height of triangle = |b-0|=b

Let p be the side of the polygon which is also the hypotenuse of the given triangle.

Apply Pythagoras theorem in right triangle, we get

Answer:

x=12

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

Step 2: Subtract 4 from both sides.

−x+4−4=−8−4

−x=−12

Step 3: Divide both sides by -1.

−x /−1 = −12 /−1

x=12

Well, we should first make it so that 4 and 8 are on one side of the equal sign and x is on the other.

  4-x=-8

+x    +x

substitute the values

[tex]tan(A)=\frac{15}{7}[/tex]

[tex]A=arctan(\frac{15}{7})=64.98\°[/tex]

For this case we have that the volume of the rectangular prism is given by:

[tex]V = A_ {b} * h[/tex]

Where:

[tex]A_ {b}:[/tex] It is the area of the base

h: It's the height

We have that the base is a triangle, so, the area of the base is the area of the triangle:

[tex]A_ {b} = \frac {9 * 4} {2} = 18 \ units ^ 2[/tex]

The height of the prism is 18 units.

So, the volume is:

[tex]V = 18 * 18 = 324 \ units ^ 3[/tex]

ANswer:

[tex]324 \ units ^ 3[/tex]

Option C

The volume of the triangular prism is 324 cubic feet (option c).

To calculate the volume of a triangular prism, you can use the formula:

Volume = (1/2) * base * height * length

In your case:

Base (b) = 9 ft

Height (h) = 4 ft

Length (H) = 18 ft

Now, plug these values into the formula:

Volume = (1/2) * 9 ft * 4 ft * 18 ft

First, multiply the numbers:

Volume = (1/2) * 9 * 4 * 18

Now, perform the multiplications step by step:

Volume = (1/2) * 36 * 18

Volume = 18 * 18

Volume = 324 cubic feet

Answer:

Mean: 5.6428571428571

Median: 5

Step-by-step explanation:

The mean is 5.64 and the median is 5 for the given data. This can be obtained by using formula for mean and median.

For finding mean and median the data should be in ascending order,

Mean = sum of observations / total number of observations

When 'n' is odd, Median = [tex](\frac{n+1}{2})^{th}term[/tex]

When 'n' is even, Median =  [tex]\frac{(\frac{n}{2})^{th} term +(\frac{n}{2}+1)^{th} term }{2}[/tex]  , where n is the number of observations.

First write the data in ascending order,

2,2,3,4,4,5,5,5,6,6,7,9,10,11

Mean = [tex]\frac{2+2+3+4+4+5+5+5+6+6+7+9+10+11}{14}[/tex] =79/14 = 5.64

Median=(5 + 5 )/2 = 5
