The discount price of socks are $21. What is the regular price

Answer:

138

Step-by-step explanation:

c=5

d=4

6c^2-5d+8

substitute c & d

6(5)^2-5(4)+8

6(25)-20+8

150-20+8 = 138

Answer:

-The equation that represents the approximate distance Aaron's dog sled team travels over time is Y = 5.32X.

-The equation that represents the approximate distance Dallas' dog sled team travels over time is Y = 5.48X.

-The equation that represents the approximate distance Mitch's dog sled team travels over time is Y = 5.42X.

Step-by-step explanation:

Given that every year, a dog sled race is held in Alaska and is approximately 1,150 miles in distance, based on the listed information, the speed rate of every racer is:

Aaron = 575 miles in 4 days and 12 hours = 575 miles in 108 hours = 5.32 mph

Dallas = 1,150 miles in 8 days and 18 hours = 1,150 miles in 210 hours = 5.476 mph

Mitch = 287.5 miles in 2 days and 5 hours = 287.5 miles in 53 hours = 5.42 mph

Therefore, the correct answers are:

-The equation that represents the approximate distance Aaron's dog sled team travels over time is Y = 5.32X.

-The equation that represents the approximate distance Dallas' dog sled team travels over time is Y = 5.48X.

-The equation that represents the approximate distance Mitch's dog sled team travels over time is Y = 5.42X.

Answer:

117 is the smaller value and 231 is the larger value

Step-by-step explanation:

Standard deviation is 57

Middle 50% is average and one standard deviation to each direction

So if the average is 174

174 - 57 is 117

174 + 57 is 231

When moving the 4 to the other side, Viet was supposed to subtract 4 from each side, leaving 0 on the left, and 102-4 on the other side. 102-4=98, not 106. Viet added when he was supposed to subtract.

Answer:

(a) [tex]s = 2.56[/tex]

(b) [tex]s = 1.71[/tex]

Step-by-step explanation:

Given

Tables (a) and (b)

Required

Determine the standard deviation

For (a):

[tex]\bar x = 11.5[/tex] --- mean

The standard deviation is calculated as:

[tex]s = \sqrt{\sum np(1-p)}[/tex]

This gives:

[tex]s = \sqrt{5*0.1*(1-0.1) +10 * 0.5 * (1 - 0.5) + 15 *0.4*(1-0.4) }[/tex]

[tex]s = \sqrt{5*0.1*0.9 +10 * 0.5 * 0.5 + 15 *0.4*0.6 }[/tex]

[tex]s = \sqrt{6.55}[/tex]

[tex]s = 2.56[/tex]

For (b):

[tex]\bar x = 4.4[/tex] --- mean

The standard deviation is calculated as:

[tex]s = \sqrt{\sum np(1-p)}[/tex]

This gives:

[tex]s = \sqrt{1*0.2*(1-0.2) +3 * 0.3 * (1 - 0.3) + 5 *0.1*(1-0.1) + 7*0.4*(1-0.4)}[/tex]

[tex]s = \sqrt{1*0.2*0.8 +3 * 0.3 * 0.7 + 5 *0.1*0.9 + 7*0.4*0.6}[/tex]

[tex]s = \sqrt{2.92}[/tex]

[tex]s = 1.71[/tex]

Answer:

The third option, y=(-1/3)x-7

Step-by-step explanation:

To find a line perpendicular to an equation, you find the negative reciprocal of the slope. For instance, if you have an equation y=4x+5, the negative reciprocal is y=(-1/4)x+5. That is the equation to find a line perpendicular to this.

If you want to find a line parallel to the equation y=4x+5, all you have to do is come up with another equation that has the same slope. So, y=4x+8 would be a line parallel to the equation y=4x+5.

I think it is possibly point b

Step-by-step explanation:

x = 20

y = 25

z = 24

plz mark my answer as brainlist plzzzz vote me also.

hope this will be helpful to you .

Answer:

x = 20

y = 25

z = 24

Step-by-step explanation:

2y + 10 = 60

2y = 50

y = 25

2y + 10 = 3x

but y = 25

=> 50 + 10 = 3x

3x = 60

x = 20

5z + 3x = 180

but x = 20

5z + 60 = 180

5z = 120

z = 24

please give me brainlist if it is helpful for you

Answer:

The company is expected to make [tex]\$ 1[/tex] on every extended warranty sold.

Step-by-step explanation:

Let [tex]X[/tex] denote whether a product with the extended warranty requires replacement in that two years. ([tex]X\![/tex] would be a random variable.) Assume that [tex]X = 1[/tex] means that the product requires replacement, and [tex]X = 0[/tex] otherwise.

Assume that this product requires replacement in that two years. That is: [tex]X = 1[/tex]. The company would then bear a cost of [tex]200 \times 1 =200[/tex] for replacing this product (since [tex]X = 1\![/tex], that cost would be the same as [tex]200 = 200 \times 1 = 200\, X[/tex].)

On the other hand, assume [tex]X = 0[/tex] (that is: this product does not require replacement in that two years.) The company would not need to pay for replacing this product. Since [tex]X = 0\![/tex], the expression [tex]200\, X[/tex] would still represent the cost for the company for this warranty.  

Either way, [tex]200\, X[/tex] would denote the replacement cost that the company would bear for this product. However, given that the company would charge [tex]\$ 11[/tex] for the extended warranty, the net revenue of the company on this warranty would be [tex]((-200) \, X + 11)[/tex]. (An earning of [tex]\$11 \![/tex] minus a spending of [tex]200\, X \![/tex].)

The question states that [tex]0.5\%[/tex] of the products would need replacement in this period. In other words, the expected value of [tex]X[/tex] would be [tex]\mathbb{E}(X) = 0.005[/tex].

The expected revenue of the company on this warranty would be:

[tex]\mathbb{E}(200\, X + 11)[/tex].

Apply the linearity of expected values to find the value of [tex]\mathbb{E}(200\, X + 11)[/tex]:

[tex]\begin{aligned}& \mathbb{E}((-200)\, X + 11) \\ &= (-200)\, \mathbb{E}(X) + 11 \\ &= (-200) \times 0.005 + 11 = 1\end{aligned}[/tex].

Hence, the company is expected to make [tex]\$ 1[/tex] on every extended warranty that it sold.

Answer:

[tex]A = (5,3)[/tex]

[tex]B = (-5,3)[/tex]

[tex]C = (-5,-8)[/tex]

[tex]D = (5,-8)[/tex]

Step-by-step explanation:

[tex]Perimeter = 42[/tex]

Construct a rectangle whose perimeter is 42 units and satisfies the given conditions.

First, name the rectangle ABCD.

Such that:

[tex]A = (x_1,y_1)[/tex]

[tex]B = (x_2,y_2)[/tex]

[tex]C = (x_3,y_3)[/tex]

[tex]D = (x_4,y_4)[/tex]

For the rectangle to be either horizontal or vertical, then:

[tex]y_1 = y_2[/tex] and [tex]y_3 = y_4[/tex]

We have that:

[tex]Perimeter = 42[/tex]

Replace perimeter with its formula

[tex]2(AB + BC) = 42[/tex]

Divide both sides by 2

[tex]AB + BC = 21[/tex]

This implies that, the distance between adjacent sides (through the edges) must be equal to 21

Having said that: a set of coordinates that satisfy the given conditions are:

[tex]A = (5,3)[/tex] -- First quadrant

[tex]B = (-5,3)[/tex] -- Second quadrant

[tex]C = (-5,-8)[/tex] -- Third quadrant

[tex]D = (5,-8)[/tex] -- Fourth quadrant

The above quadrants satisfy the condition:

[tex]y_1 = y_2[/tex] and [tex]y_3 = y_4[/tex]

HOW TO KNOW THE PERIMETER IS 42

To do this, we simply calculate the distance between the edges and add them up

Distance is calculated as:

[tex]D = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2[/tex]

For AB

[tex]A = (5,3)[/tex]

[tex]B = (-5,3)[/tex]

[tex]D_1 = \sqrt{(5 - (-5))^2 + (3 - 3)^2}= \sqrt{(10)^2 + (0)^2} = \sqrt{100} = 10[/tex]

For BC

[tex]B = (-5,3)[/tex]

[tex]C = (-5,-8)[/tex]

[tex]D_2 = \sqrt{(-5 - (-5))^2 + (3 - (-8))^2}= \sqrt{(0)^2 + (11)^2} = \sqrt{121} = 11[/tex]

For CD

[tex]C = (-5,-8)[/tex]

[tex]D = (5,-8)[/tex]

[tex]D_3 = \sqrt{(-5 -5)^2 + (-8 - (-8))^2}= \sqrt{(-10)^2 + (0)^2} = \sqrt{100} = 10[/tex]

For DA

[tex]D = (5,-8)[/tex]

[tex]A = (5,3)[/tex]

[tex]D_4 = \sqrt{(5 -5)^2 + (-8 -3)^2}= \sqrt{(0)^2 + (11)^2} = \sqrt{121} = 11[/tex]

So, the perimeter is:

[tex]P = D_1 + D_2 + D_3 + D_4[/tex]

[tex]P = 10 + 11 + 10 +11[/tex]

[tex]P = 42[/tex]

Step-by-step explanation:

That statement is true based on the graph.

Answer:

4.75 if you don't have to convert it to US dollars.

Step-by-step explanation:

1. The question is asking how much is the cost of each sachet.

2. One given fact is that 6 pieces of a sachet cost 28.50.

3. Division.

4. Can't tell if you're asking for the equation but 28.50 / 6 = 4.75. Or do 28.50 / 6 = c

5. 4.75.

If they're asking you to convert it into united states dollars:

1. It's asking how much is the cost of each sachet.

2. One given fact is that 6 pieces of a sachet cost 28.50.

3. Division.

4. Can't tell if you're asking for the equation but 28.50 / 49 = 0.58163265306 (0.59 if you round it) Or do 28.50 / 49 = c

5. 0.59.
