HELLLLLLLPPPPPPPPPPPP PLEASEEEEEEEEEE.

Thirty students in an art class each receive an identical set of 20 markers. As part of a project, each student is asked to close their eyes and select from his or her set at random. You developed a model that predicts the probability of a student randomly picking a yellow marker is 0.1. Which result would most likely cast doubt on your model? (Hint: what is the theoretical probability of 30 students choosing a yellow marker each from a pack of 20 markers.)

10 student pick red markers.
10 student pick yellow markers.
2 student pick blue markers.
2 student pick yellow markers.
3 students pick yellow markers.
3 students pick green markers.

Answer:

x = 3

y = 6

Step-by-step explanation:

-4x- y = -18

2x + 3y = 24 (Multiply everything by 2)

-4x - y = -18

4x + 6y = 48

5y = 30

y = 6

-4x- y = -18

-4x - 6 = -18

-4x = -12

x = 3

Answer:

$511.7

Step-by-step explanation:

Given data

Cost of stereo system= $480.50

Tax= 6 1/2% = 6.5%

Let us find the amount of the tax

=6.5/100*480.5

=0.065*480.5

=$31.2

Hence the amount of the tax = $31.2

Therefore the total cost is

=31.2+480.50

=$511.7

Answer: Its 33 !

Step-by-step explanation:

Okay so its actually not that bad at all !

So STEP 1

Convert your percent into a decimal : 65% -->  .65

STEP 2 you still following me you got this !

since kaitlyn attempts to throw  50  free throws all you need to do is multiply your decimal you converted by 50

it would look like this   .65 X 50 = 32.5

Step 3

Depending on what your answer choices are 32.5 is going to have to be rounded upwards remember anything at or above 5 you round up. Anything below 5 you round down so your answer will be  33 in this problem

Summary  

when seeing questions like this  convert that percent into a decimal  then depending on what is being counted for. you multiply your decimal by the number !  Hope this helps thanks for reading <3

Answer: NO SOLUTIONS

Step-by-step explanation:

8a-3=5a+35+3a

8a-3=8a+35

-8a     -8a

-3 does not equal to 35

NO SOLUTIONS

Answer: 8a=38+8a²

Step-by-step explanation:

8a-3=5(a+7)+3a

8a-3=5a+35+3a

8a-3=8a²+35

8a=35+3+8a² (I moved 3 to put it with 35 because they are the same, I couldn't do the same for 8a and 8a² because of the 2)

8a=38+8a²

Answer:

the approximate value after 6 years is $443

Step-by-step explanation:

The computation of the approximate value after 6 years is shown below:

= Current value × (1 + rate of interest)^number of years

= $250 × (1 + 0.10)^6

= $250 × 1.1^6

= $442.8903

= $443

Hence, the approximate value after 6 years is $443

Therefore the last option is correct

Answer:

The box volume is 240 in^3

Step-by-step explanation:

The volume of a rectangular box is V = L*W*H.

Here, that would be V = (10 in)(8 in)(3 in)= 240 in^3

Answer:

Volume is 240 inches

Step-by-step explanation:

Volume = Length x Width x Height

 L    W   H       V

10 x 8 x 3 =  240 inches

Answer:

216 plants

Step-by-step explanation:

To answer this question :

Area of a triangle = 1/2 x base x height

1/2 x 9 x 12 = 54 yards²

54 x 4 = 216 plants

Answer:

(2)   6.1

tep-by-step explanation:

∠Y is a right angle, so ΔXYZ is a right triangle

[tex]XZ^{2} = XY^{2} + YZ^{2}[/tex]

[tex]XZ^{2} = 7^{2} + 10^{2}[/tex] = 49 + 100 = 149

XZ = [tex]\sqrt{149}[/tex] = 12.2

XZ is the diameter of the semicircle, therefore, the radius is 12.2/2 = 6.1

Answer:

x = 130°

Step-by-step explanation:

number of sides = 6

the sum of the total interior angles = (6 x 180) - 360 = 720°

x = 720 - 125 - 120 - 100 - 120 - 125 = 130°

Answer:

i could be wrong sorry

It should look like this:

Answer:

Step-by-step explanation:

3/4 cups → 1 batch

x cups    → 2 batches

x = 2(3/4) = 6/4 = 1 1/2 cups

3/4 cups → 1 batch

y cups → 9 batches

y = 9(3/4) = 6 3/4 cups

Step-by-step explanation:

What you don't know. which chapter is hard for you?

Answer:

Step-by-step explanation:

From the given x^2 - 8x + 13 we can find several points to graph to represent this quadratic function.

The y-intercept is (0, 13) and stems from letting x = 0.

                                                 b

The axis of symmetry is x = - -----

                                                 2a

                                                                                    -8

Since a = 1 and b = -8, the axis of symmetry is x = - ------- = 4

                                                                                      2(1)

and so the vertex is at (4, 4^2 - 8(4) + 13), or (4, -3)

If you want to go the extra mile, find the roots of the given equation.  These are also your x-intercepts.  One such intercept is (2. 0).  

Plot these points and draw a smooth curve through them.

Hint:  the parabolic graph opens up.

Answer:

54degrees

Step-by-step explanation:

Find the diagram attached

Since the angle of the triangle in a semicircle is a right angle, hence <DCB = 90 degrees

Given

<DBC= 36 degrees

Required

<DBC

Since the sum of angles in the triangle DBC is 180 degrees, hence;

<DBC+<DBC+<DCB = 180

<DBC+36+90 = 180

<DBC + 126 = 180

<DBC = 180 - 126

<DBC = 54degrees

Hence the measure of angle DBC is 54degrees
