Answer:

The greatest common factor for 18,42 and 96 is 6.

Step-by-step explanation:

6 X 3 = 18

6 X 7 = 42

6 X 16 = 96  

making 6 your largest common factor.

Answer:

let x be chips and y be sodas

8x + 4y = 5 ---> for the first hint

4x + 8y = 7------> second hint

0.25 cents is how much chips costs

and 0.75 cents is how much sodas costs

Answer: Each bag of chips is $0.25, each soda is $0.75.  

(0.25 x 8) + (0.75 x 4) = 5

2 + 3 = 5

(0.25 x 4) + (0.75 x 8) = 7

1 + 6 = 7

Answer:

2x^3+8x^2-23x+6

Step-by-step explanation:

Multiply each term in the first expression (x+6) by each term in the second expression (2x^2-4x+1) and then combine like terms.

The apothem is the perpendicular distance from the center of a regular polygon to any one of its sides.

The apothem of a regular polygon is the perpendicular distance from the center of the polygon to any one of its sides because it serves as a measure of the inradius, or the radius of the circle inscribed within the polygon. In a regular polygon, all sides are congruent and all interior angles are equal, so the apothem is the same for all sides.

To see this, imagine drawing radii from the center of the polygon to each vertex, and then drawing the perpendicular bisector of each side. These perpendicular bisectors will all intersect at the same point, which is the center of the polygon. The apothem is the length of the line segment connecting this center point to any one of the sides of the polygon.

The apothem is useful in finding the area of a regular polygon. By using the formula for the area of a regular polygon in terms of the apothem and the number of sides, one can find the area of a regular polygon without having to find the exact shape of the polygon.

Answer:

Step-by-step explanation:

hi

Answer:

A 3 1/2

Step-by-step explanation:

There are a number of ways that you can solve this

Method 1)

Since these proportions are set equal to each other, we know that x is also equivalent to 1/2. So, we need to find the whole-number that was multiplied by the first fraction (1/2/4) that gave us the second fraction (x/28).

So we need to divide the denominators

28/4 = 7

Now that we have that number, we will mutiply 1/2 by it because we know that whatever x is the 1/2 times 7 since 28 is 4*7:

1/2 * 7 = 3.5 or 3 1/2, so 3 1/2 is our answer...

Another way that we can solve this is by using the cross product (butterfly method)

Method 2)

Multiply 28 by 1/2 = 14.

Now we will divide 14 by 4. 14/4 = 3.5

3.5 = 3 1/2, so that is our answer.

Answer:  approximately 24 square units in the shaded areas

Step-by-step explanation:  

The area of the entire dark circles will be for each πr², then divided by 2 to get the area of the semicircles created on the sides of the triangles:

16π + 9π = 25π   Half that times value for pi

≈ 39.2699  is the area of the dark semicircles. Round to 39.27

Now the fun! Find the area of the parts subtracted by the light semicircle:

The area of the entire circle is 25π  or about 78.54. The triangle is half of an inscribed rectangle, 6×8, so 48.  Subtracted from the circle leaves about 30.54 in the four slices between the arcs of the circumference and the perimeter of the rectangle. We are concerned with only half of the slices, so we will subtract 15.27

Area of the dark semicircles minus the area of the light slices will leave the area of the shaded crescents:

Answer:

see below

Step-by-step explanation:

To find the conjugate of a+bi take the opposite of bi so it would be a - bi

7-3i, the conjugate is 7 + 3i

8+2i  the conjugate is 8 -2i

The product of a number and its conjugate is

(a+bi) (a-bi) = a^2 +abi-abi -b^2 i^2 = a^2 - b^2 (-1) = a^2 + b^2

( 4-i) ( 4+i) = 4^2 + 1^2 = 16+1 = 17

( 6+3i)(6-3i) = 6^2 + 3^2 = 36+9 = 45

#1

\(\\ \sf\longmapsto \overline{z}=7+3i\)

#2

\(\\ \sf\longmapsto \overline{z}=8-2i\)

#3

\(\boxed{\sf z\overline{z}=|z|^2}\)

\(\\ \sf\longmapsto z=4-i\)

\(\\ \sf\longmapsto |z|^2=4^2+(-1)^2\)

\(\\ \sf\longmapsto 16+1=17\)

#4

\(\\ \sf\longmapsto |z|^2\)

\(\\ \sf\longmapsto 6^2+3^2\)

\(\\ \sf\longmapsto 45\)

The statement is false. A process chart is a graphical tool used to monitor processes in production and service industries. The average process performance and the upper and lower limits are calculated and displayed on an X-bar chart, which is a common process chart.

An \( \bar{X} \) chart is NOT used to track a process with binary outcome variables. The statement is false.

Explanation: A process chart is a graphical tool used to monitor processes in production and service industries. The average process performance and the upper and lower limits are calculated and displayed on an X-bar chart, which is a common process chart. The values for a variable can be collected and analyzed using process charts. An \( \bar{X} \) chart, commonly known as an x-bar chart, is used to monitor a process with continuous numerical data. A binary outcome variable, on the other hand, has only two possible outcomes (e.g., yes/no, pass/fail, etc.). As a result, binary data is unsuitable for an \( \bar{X} \) chart, which is only used to monitor continuous numerical data.

Variables are values that may be altered in a process, which can affect its results. Variables may be categorized as continuous or discrete, depending on whether they can be measured or counted. Discrete variables, such as the number of employees working on a task or the number of items produced in a process, are quantifiable and can be measured precisely. Continuous variables, such as the temperature, length, or weight, can take on any value over a range and are therefore less specific. The reasons for holding inventory include serving as a buffer against uncertainties, ensuring product availability and preventing stockouts, reducing lead times and transportation costs, taking advantage of discounts and bulk purchasing opportunities, and providing a hedge against inflation and price fluctuations.

Answer:

D. This is a Square Pyramid.

Step-by-step explanation:

The correct number of servings is 7(1)/(2) or 7.5 servings.

To find the correct number of servings, we need to divide the total amount of soup made by the amount of soup served per serving.

Total soup made = 4(1)/(2) quarts

Amount served per serving = (3)/(5) quart

Number of servings = Total soup made / Amount served per serving

Number of servings = (4(1)/(2)) / (3)/(5)

To simplify this expression, we can convert the mixed number 4(1)/(2) to an improper fraction:

4(1)/(2) = (2 * 4 + 1) / 2 = 9/2

Now we can substitute the values into the equation:

Number of servings = (9/2) / (3/5)

Number of servings = (9/2) * (5/3)

Number of servings = (9 * 5) / (2 * 3)

Number of servings = 45 / 6

Number of servings = 7(1)/(2)

Therefore, the correct number of servings is 7(1)/(2) or 7.5 servings.

Hector made a mistake by calculating 3_(5)^(3) servings. The correct representation would be 3(5/8) servings, which is different from 7.5 servings.

The value of dfbetween in the analysis of variances is 2. Thus option D is correct option.

According to the statement

we have given that the df total = 29 and df within = 27. And we have to find the value of the df between.

So, For this purpose, we know that the

Analysis of variance (ANOVA) is an analysis tool used in statistics that splits an observed aggregate variability found inside a data set into two parts.

So, Df between values are the values between the value of dftotal and dfwithin.

Here df total = 29 and df within = 27

So, df between = df total - df within

Substitute the values in it then

df between = df total - df within

df between = 29 - 27

df between = 2.

So, The value of dfbetween in the analysis of variances is 2. Thus option D is correct option.
