Find the mean and median for the graph?

Answer:

12

Step-by-step explanation:

The proportion is equal to [tex]\frac{x}{10}=\frac{42}{35}[/tex]

We can simplify the right side by dividing by 7/7 to get the right side equal to 6/5. Now we can cross-multiply to get

[tex]60=5x[/tex]

Dividing both sides by 5, we have the answer as

[tex]x=12[/tex]

Answer:

option D.

Step-by-step explanation:

[tex]rate \: of \: change \: = \frac{change \: in \: y}{change \: in \: x} [/tex]

let's take any point on the graph. let's say (2, 16)

and one point we know is (0, 0)

[tex]rate \: of \: change = \frac{16 - 0}{2 - 0} [/tex]

= 16($) / 2 (hrs)

= 8 $/ hrs

that is option D.

Answer:

$8/hour

Step-by-step explanation:

Hi there!

In this scenario, the independent variable is time and the dependent variable is the cost. The cost of renting the kayak depends on how much time passes. Knowing this, the answer should be formatted like _ dollars/hour, not _hours/dollar. We can rule the first two options out.

Now, looking at the graph, when 1 hour passes, the cost is $8. This occurs at point (1,8). And this is constant throughout, for example, when 2 hours pass, the cost is $16 (2,16).

Therefore, the rate of change shown in the graph is $8/hour.

I hope this helps!

Answer:

y = 2x + 4

Step-by-step explanation:

(x₁ , y₁) --> (0 ,4)    & (x₂ , y₂) = (6 , 16)

Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\[/tex]

          [tex]= \frac{16-4}{6-0}\\\\=\frac{12}{6}\\\\m = 2[/tex]

(x₁  , y₁) --> (0 ,4)

y - y₁ = m(x - x₁)

y - 4 = 2(x - 0)

y - 4 = 2x

   y = 2x + 4

Just did this problem! Hope it helps

The proofing that ABCD is a parallelogram is done using parallelogram side theorem.

parallelogram side theorem simply means that the opposite sides of a parallelogram are equal and also parallel to each other.

As, ABCD is a parallelogram.

So, BAC and DCA are alternate interior angles.

Also, AB||CD and BC||DA.

then, BCA and DAC, are alternate interior angle.

Now In ABC and CDA

BAC= DCA (proved above)

BCA= DAC (proved above)

AC= AC (Common)

By ASA congruency criteria,

ΔABC≅ ΔCDA

Hence, AB= CD and BC= DA (cpctc)

Remark

This is a regular pentagon. The information given is enough the find the area of 1 triangle. There are 5 such triangles. So find the area of 1 of the triangles. The answer will be 5 times as much.

Givens

b = 18.3

h = 12.6

Formula

1 triangle = 1/2 * b * h

5 such triangles = 5 times as much

Solution

Area(1_triangle) = 1/2 * 18.3 * 12.6

Area (1_triangle) = 115.29

The ratio 4:3 means for every 4 girls there are 3 boys.

Divide total girls by 4, multiply that by 3 to get total boys:

180/4 = 45 x 3 = 135

There are 135 boys

For total students add boys and girls:

180 + 135 = 315 total students

Answer:

  3) x = 55, y = 123, z = 123

  4) x = 276°

Step-by-step explanation:

Angles P and Q are alternate interior angles, so are congruent.

  P = Q

  3x -42° = 2x +13°

  x = 55° . . . . . . . . . . . add 42°-2x

Then Q = 2x +13 = 2(55°) +13° = 123°.

Angles Y, P, Q, and Z are all congruent, so all have the same measure.

  Y = Z = 123°

__

If you draw a horizontal line parallel to AB and CD through point O, then small angle POQ is divided into parts that are congruent with angles APO and CQO. That is, small angle POQ = 48° +36° = 84°.

Large angle POQ is then 360° -84° = 276°

Answer:

2x^2+10x+2

Step-by-step explanation:

12x^2 +5x+1 - ( 10x^2 -5x-1)

Distribute the minus sign

12x^2 +5x+1 -  10x^2 +5x+1

Combine like terms

2x^2+10x+2

Step-by-step explanation:

Right on Edge

Given:

The vertex of a triangle MNP are M(-4, 6), N(2, 6), and P(-1, 1).

The rule of dilation is:

[tex](x,y)\to (1.5x,1.5y)[/tex]

The image of triangle MNP after dilation is M'N'P'.

To find:

The coordinates of the endpoints of segment M'N'.

Solution:

The end points of MN are M(-4, 6) and N(2, 6).

The rule of dilation is:

[tex](x,y)\to (1.5x,1.5y)[/tex]

Using this rule, we get

[tex]M(-4,6)\to M'(1.5(-4),1.5(6))[/tex]

[tex]M(-4,6)\to M'(-6,9)[/tex]

And,

[tex]N(2,6)\to N'(1.5(2),1.5(6))[/tex]

[tex]N(2,6)\to N'(3,9)[/tex]

The endpoints of M'N' are M'(-6, 9) and N'(3, 9).

Therefore, the correct option is B.

Answer:

D

Step-by-step explanation:

First of all, you are moving right. That means that something gets added or subtracted from the x

To move right whatever number units you move right, will be subtracted from the x.

A and B are are both wrong. It is really the y that the +/- ten changes.

C is wrong because you are moving left, not right.

D is the answer. It is not intuitive, but it is how how move right.

Step-by-step explanation:

To make 1 sundae, the total number of spoons use of sprinkles=4. Let the number of sundaes made in 32 spoonfuls of sprinkles be x. Also the number of sprinkles and the number of sundaes are directly proportional. Therefore, Hence, if 32 spoonfuls of sprinkles is used, then the ice-cream shop can make 8 sundaes.

Answer:

1000 cm²

Step-by-step explanation:

perimeter = 2 * length + 2 * width

2 * 5x + 2 * 2x = 140

10x + 4x = 140

14x = 140

x = 10

Length: 5x = 5(10) = 50

Width: 2x = 2(10) = 20

area = length * width

area = 50 cm * 20 cm

area = 1000 cm²

Respuesta:

S / 75

Explicación paso a paso:

Dado :

Para pedidos de hasta una docena; par de pantimedias Glamour Costo S / 5

Para pedidos de más de una docena; par de pantimedias Glamour Costo S / 3

Función de costo:

Para x ≤ 12

Costo, C = 5x

Para x> 12

Costo, C = 3x

Costo de 5 pedidos:

x = 5

Costo, C = 5 (5) = S / 25

Costo de 15 pedidos:

x = 15

Costo, C = 3 (15) = S / 45

Costo de 25 pedidos:

x = 25

Costo, C = 3 (25) = S / 75

Answer:

A

Step-by-step explanation:

1500 goats represent 100%

                              but 100% = 5*20%

1500 = 5*300 so 20% =300

a decrease by 20% is 1500-300 = 1200

When multiplying with the same base, add the exponents

A 3^1 * 3^-10  = 3^-9

B 3^-1 * 3^10 = 3^9

C 3^-4 * 3^7 = 3^3

D 3^3 *3^-7 = 3^-3

Answer:

C. 32

Step-by-step explanation:

The shipment for 100 parts is received by a manufacturer. Shipment will be rejected if more than 5 parts are defective. The manufacturer selects a sample and based on that selected sample he accepts or rejects the whole shipment. The minimum size of the sample should be 32 based on the probability of less than 0.1 and then  decision should be made whether to accept or reject the shipment. If no defective part is found in the sample, shipment should be accepted.
