Data Set B: 26, 29, 39, 40, 52

Variability means you have more range so....

Answer:

X=30

Step-by-step explanation:

The whole polygon is 360 degrees so:

360-28-40-120-142=X, which is 30

The value of x = 30°.

As in the case with a regular polygon, an irregular polygon even contains exterior angles that count up to 360°. Each exterior angle in an irregular polygon even exists (180° - its linear pair). Therefore the exterior angles add up to 360°.

The entire external angle is equal to 360.

28° + 40° + 120° + 142° + x = 360°

Simplifying the above equation, we get

330° + x = 360°

x = 360°- 330°

x = 30°

Therefore, the value of x = 30°.

x < 21.01 or x > 21.49 because |x - 21.25| > 0.24

Step-by-step explanation:

We know that each pack of almonds is targeted to weigh 21.25 oz.and a pack must weigh within 0.24 oz of the target weight to be accepted.

Assuming x to be the weight of a given pack of almonds, we can write it as:

[tex]|x-21.25| > 0.24[/tex]

Now finding the range of rejected masses (x) of the almonds.

[tex]|x-a| >b[/tex]

[tex]-b<(x-a)< b[/tex]

[tex]|x-21.25| >0.24[/tex]

[tex]-0.24>(x-21.25)>0.24[/tex]

[tex]-0.24>x-21.25[/tex] or [tex]x-21.25>0.24[/tex]

[tex]x<21.01[/tex] or [tex]x>21.49[/tex]

Therefore, the correct answer option is x < 21.01 or x > 21.49 because |x - 21.25| > 0.24.

To solve this type of equations that only involve one variable, we have to isolate the variable at on side of the equation. So, for the given equation

We will subtract 21 from both sides

-b+21-21=-13-21

-b= -34

As the minus sign is on both sides of the equation, it will be cancelled and

b=34

Answer:

A reflection across the x-axis.

Step-by-step explanation:

A reflection across the x-axis changes the signs of the y-coordinates like it does in the problem. (3, 2) becomes (3, -2) and (2, -3) becomes (2, 3).

I hope this helps!

ANSWER

Reflection in the x-axis

EXPLANATION

The given line segment has endpoints at (3,2) and (2,-3).

After this point are reflected the image points are:

(3,-2) and (2,3)

We can observe that the y-coordinates were negated to obtain the image points hence the mapping for the reflection is;

[tex](x,y)\to(x,-y)[/tex]

This is a reflection in the x-axis.

Answer:

[tex]f(x) = \frac{1}{16}x^2[/tex]

Step-by-step explanation:

If the graph of the function [tex]y=f(hx)[/tex]  represents the transformations made to the graph of [tex]y= f(x)[/tex]  then, by definition:

If [tex]0 <h <1[/tex] the graph is stretched horizontally  by a factor [tex]\frac{1}{h}[/tex]

If [tex]h> 1[/tex] the graph is compressed horizontally by a factor [tex]\frac{1}{h}[/tex]

In this problem we have the parent function [tex]y=x^2[/tex] And we know that it stretches horizontally by a factor of 4

Therefore

[tex]0 <h <1[/tex]  and [tex]h=\frac{1}{4}[/tex]

The transformation is:

[tex]y=f(\frac{1}{4}x)[/tex]

And the function is:

[tex]f(x) = (\frac{1}{4}x)^2[/tex]

It is in the hundredths place

Hundredths

Two places after the decimal is always the hundredths place.

for a rational expression the vertical asymptotes occur when the denominator equals 0, in this case that will be when x + a = 0.

now, if there were to be a vertical asymptote of x = 1, that simply means that

x = 1 ==> x - 1 = 0.

meaning that a = -1.

horizontal asymptotes occur when the denominator has a higher degree than the numerator OR when both have the same degree.

when the degree of the denominator is higher, then the only horizontal asymptote occurring is y = 0.

when the degrees are the same, then the horizontal asymptote occurs at the leading terms' coefficient fraction.

now, if this expression were to have a horizontal asymptote of y = 2, that simply means

[tex]\bf \cfrac{2x^m}{x+a}\implies \cfrac{2x^1}{1x^1+a}\implies \stackrel{\textit{horizontal asymptote}}{\cfrac{2}{1}\implies y=2}\qquad \textit{meaning m = 1}[/tex]

ANSWER

a=-1,m=1

EXPLANATION

The given function is

[tex]f(x) = \frac{2 {x}^{m} }{x + a} [/tex]

For this rational function to have a horizontal asymptote at y=2, the degree of the numerator must equal the degree of the denominator.

This implies that, we must have m=1.

For the function to have a vertical asymptote at x=1, then,

[tex]1 + a = 0[/tex]

This implies that,

[tex]a = 0 - 1[/tex]

[tex]a = - 1[/tex]

The correct choice is the third option.

Answer:

[tex]=\frac{3x^{5}(y-z)}{2(y+z)}[/tex]

Step-by-step explanation:

[tex]\frac{15x^3 (y-z)^2}{10x^{-2}(y^2-z^2)}[/tex] We need to solve this equation.

We know (x^2-y^2) = (x-y) (x+y)

Using the above formula, and taking 5 common:

[tex]=\frac{3x^3 (y-z)^2}{2x^{-2}(y^2-z^2)}\\=\frac{3x^{3+2} (y-z)^2}{2(y^2-z^2)}\\=\frac{3x^{5} (y-z)(y-z)}{2(y-z)(y+z)}\\=\frac{3x^{5}(y-z)}{2(y+z)}[/tex]

Final answer:

To simplify the expression, distribute the -1.01 across the parentheses, combine like terms, and the simplified result is 14.652c - 21.22b. Given values for a, b, and c are not needed.

Explanation:

To simplify the algebraic expression 9.4c - 1.01∙(22b - 5.2c) + b, we first distribute the -1.01 across the parentheses, and then combine like terms.

Step-by-Step Explanation:

Distribute -1.01 to each term inside the parentheses: -1.01 * 22b = -22.22b, and -1.01 * (-5.2c) = 5.252c.

Combine the distributed terms with the original expression: 9.4c - 22.22b + 5.252c + b.

Combine like terms: (9.4c + 5.252c) + (b - 22.22b).

Adding c terms together gives 14.652c, and combining b terms gives -21.22b(because 1b - 22.22b equals -21.22b)

The simplified expression is now 14.652c - 21.22b.

Note: The given values a = 1, b = 0.0211, and c = -0.0211 are not relevant to the simplification process.

Answer:

f(x) = 10 [ (x + 4)^2 = -6 ]

Step-by-step explanation:

Please use " ^ " to indicate exponentation.  Thanks.

Also, please share the possible answer choices.  "Select the best answer from the choices provided."

Start with f(x) = 10x^2 + 80x + 220 = 0

Factor out the 10 to simplify this "completing the square."

f(x) =  10(x^2 + 8x + 22) = 0

Complete the square of x^2 + 8x + 22 only, for now.

Identify the coefficient of the x term.  It is 8.  Take half of that (it is 4) and square your result:  16

Now add 16 to x^2 + 8x  and then subtract 16 from that sum:

x^2 + 8x + 16 - 16 + 22 = 0, or

x^2 + 8x + 16      + 6     = 0

Rewrite x^2 + 8x + 16  as (x + 4)^2

and then the whole expression x^2 + 8x + 16 - 16 + 22 as (x + 4)^2 = -6

Finally, rewrite this as

f(x) = 10 [ (x + 4)^2 = -6 ] which is the desired form of the original equation.

Answer:

The answer is

[tex](x+4)^2=-6[/tex]

Step-by-step explanation:

Follow the steps below.

1) Take common factor 10

[tex]10(x^2 + 8x + 22) = 0[/tex]

2) For an equation of the form [tex]ax ^ 2 + bx + c[/tex]

Calculate [tex](\frac{b}{2})^2[/tex]

In this case the equation is [tex]x^2 + 8x + 22= 0[/tex]

[tex]a=1\\b=8\\c =22\\\\(\frac{b}{2})^2 = (\frac{8}{2})^2 = 16[/tex]

3) Add 16 on both sides of equality

[tex]10(x^2 + 8x + 16) +220= 16*10[/tex]

4) Factor the expression into parentheses and simplify

[tex]10(x+4)^2 +220= 16*10[/tex]

[tex]10(x+4)^2= 16*10-220[/tex]

[tex]10(x+4)^2 =-60[/tex]

[tex](x+4)^2 =-6[/tex]

Step-by-step explanation:

Answer:

w =  120 + 5*(h-30)

Step-by-step explanation:

Part A;

We are informed that Andrew is paid $4 per hour for the first 30 hours he works each week and makes $5 per hour for each hour he works over 30 hours per week. This implies that the  $4 per hour for the first 30 hours is fixed while the $5 per hour overtime depends on the number of extra hours worked.

If we let w denote the wage and h denote the hours worked per week, then;

$4 per hour for the first 30 hours; 4*30 = 120

The number of extra hours worked would be; h-30

w =  120 + 5*(h-30)

This is the function that gives Andrew’s total wages when he works more than 30 hours each week.

Adrian will need 4 3/8 cups of raisins to bake 2 1/2 batches.

Convert the mixed fractions into improper fractions:

1 3/4 = 7/4

2 1/2 = 5/2

Multiplying fractions:

1) Multiply numerators

2) Multiply denominators

3) Simplify answer

7/4 * 5/2 = 7*5 / 4*2 = 35/8

35/8 can be simplified into a mixed fraction 4 3/8 

Adrian needs to use 4 3/8 cups of raisins.

Answer:

4 3/8

Step-by-step explanation:

Step 1: Convert the numbers into improper fractions. To do this, multiply the denominator value by the whole number and then add the numerator to that product. 1 3/4 becomes 7/4 and 2 1/2 becomes 5/2.

Step 2: Multiply the fractions straight across. Multiply the numerators together and the denominators together. 7 * 5 is 35. 4 * 2 is 8. The improper fraction is 35/8.

Step 3: Convert the improper fraction to a mixed number. Do this by dividing the numerator by the denominator. 35/8 is 4 with a remainder of 3/8. 4 3/8 is the number of cups he will use to make his batches of muffins.

Answer:

B: x + 12 = 35 and subtract 12 from both sides. The answer is 23.

Step-by-step explanation

Equation of 'The sum of a number and twelve is thirty-five' is x + 12 = 35 and the solution is 23

Let the number be x

the sum of the numbers x and 12 means  x + 12

The sum of a number x and 12 is 35 means x + 12 = 35

x + 12 = 35

subtract 12 from both sides

x + 12 - 12 = 35 - 12

x = 23

Therefore, the correct option is 'Write the equation as x + 12 = 35 and subtract 12 from both sides. The answer is 23.'

The product costs $0.37 per ounce.

Step-by-step explanation:

$29.75 for 5 pounds = x for 1 pound (Cross-Multiply)

5x/5 = $29.75/5

x = $5.95 per pound

$5.95 per pound/16 ounces = $0.37

$0.37 per ounce!

Answer:

$0.371875 does it cost per ounce.

Step-by-step explanation:

Use conversion:

1 pound = 16 ounces.

As per the statement:

A product costs $29.75 for 5 pounds.

In 5 pounds = product cost $ 29.75

then;

In 1 pound = [tex]\$\frac{29.75}{5}[/tex]

Using conversion we have;

In 16 ounces = [tex]\$\frac{29.75}{5}[/tex]
