9 the rolls will result in a sum greater than 10 if the experiment is repeated 108 times.

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

The theoretical probability of both rolls equaling a sum greater than 10 is 3 over 36.

As, Expected number of outcomes = theoretical probability * number of trials

Expected number of outcomes = 3/36 x 108

                                                    = 9

Thus, the required value is 9.

Answer: 70%

Step-by-step explanation:

The total answers count 30 - it's 100%, so to get a 1% value, divide 30 by 100 to get 0.30. Next, calculate the percentage of 21: divide 21 by 1% value (0.30), and you get 70.00%

Answer: 40!

Please give brainliest.

Step-by-step explanation:

Let us first diagnose the problem.

There is a die with 6 sides.

Sides: 1,2,3,4,5,6

4 of the 6 sides are greater than 2.

Let us use the theoretical probability formula of
Number of favorable outcomes / Number of possible outcomes.

Favorable outcomes being 4 because there is 4 numbers greater than 2, which is favorable to the outcome we want

Possible outcomes being 6 because the die has 6 sides.

Now lets put this in a fraction:

[tex]\frac{4}{6}[/tex]

Lets multiply our fraction by 60, as we are rolling the die 60 times.

[tex]\frac{4}{6} (60) = 40[/tex]
We got 40! Which basically means 40%.

The lengths of sides BC, DE, and EC in triangle DEC are given as [tex]4[/tex] feet, [tex]1.8 feet,[/tex] and 0.8 foot, respectively. The length of side [tex]AB[/tex] is approximately [tex]3.36[/tex] feet.

Part A:

To draw triangles  [tex]ABC[/tex] and  [tex]DEC[/tex] separately, follow the steps below:

Draw a straight line segment DE with length  [tex]1.8[/tex] feet.

From point D, draw a line segment DC perpendicular to DE with length 4 feet.

Connect point E and point C with a straight line segment EC.

From point B, draw a line segment BE perpendicular to BC with length 0.8 foot.

Draw a straight line segment BC that intersects line segment DC at point A.

Connect point A and point B with a straight line segment AB.

The lengths of sides BC, DE, and EC in triangle DEC are given as [tex]4[/tex] feet, [tex]1.8 feet,[/tex] and 0.8 foot, respectively.

Part B:

Since triangles  [tex]ABC[/tex] and [tex]DEC[/tex] are similar, their corresponding sides are proportional. Let x be the length of side AB. Then we have:

[tex]AB/DE = BC/EC[/tex]

Substituting the given values, we get:

[tex]x/1.8 = BC/0.8[/tex]

Solving for BC, we get:

[tex]BC = 0.8x/1.8[/tex]

Since BC and EC are the two legs of a right triangle DEC, we can use the Pythagorean theorem to find BC:

[tex]BC^2 + EC^2 = DE^2[/tex]

Substituting the given values, we get:

[tex](0.8x/1.8)^2 + 4^2 = 1.8^2[/tex]

Solving for x, we get:

[tex]x = 1.8 * (sqrt(1.8^2 - 4^2)) / 0.8[/tex]

[tex]x \approx 3.36 feet[/tex]

Therefore, the length of side [tex]AB[/tex] is approximately [tex]3.36[/tex]  feet.

.32

So the trick here is to look at the decimals. We can solve this problem like it’s 16×2, as long as we add the decimal points back in. so in this case the decimal points are in the tenths spot so we move them twice in the 32. I hope the picture helps too. Hope this helped!

Answer:

Step-by-step explanation:

#18 complementary

3x +45 = 90

3x + 45-45 = 90 -45

3x = 45

Divide both sides by 3

3x/3 = 45/3

x = 15

#20 supplementary

2x + 3x + 25 = 180

5x + 25 = 180

5x + 25 - 25 = 180 -25

5x = 155

Divide both sides by 5

5x/5 = 155/5

x = 31

#15 - vertical

4x - 25 = 75

4x - 25 + 25 = 75 + 25

4x = 100

Divide both sides by 4

4x/4 = 100/4

x = 25

#16 - complementary

4x + 2x = 90

6x = 90

divide by 6 each side

x = 15

#19 complementary

x -20 + x = 90

2x -20 = 90

2x -20 + 20 =90 +20

2x = 110

Divide both sides by 2

2x / 2 = 110/2

x = 55

now isolate the variable:

432/18 = 18n/18

24 = n

Step-by-step explanation:

The solution of for the system of linear equations shown in the graph is x = -1/2 and y = 3/2.

Given points of two lines:-

Line 1 : (0,0) , (1,-3)

Line 2 : (0,2) , (-1,1)

Let the Equation of Line 1 : y = mx + c

m = (-3-0)/(1-0) = -3/1 = -3

Putting (0,0) in  y = mx + c, we get

0 = -3*0 + c

0 = 0 + c

c = 0

Hence,

Equation of Line 1 : y = -3x or y + 3x = 0  ...(1)

Similarly, we can find,

Equation of Line 2 : y = x + 2 or y - x = 2  ...(2)

(1) - (2),

4x = -2

x = -2/4 = -1/2

Putting the value of x in (2), we get,

y - (-1/2) = 2

y + 1/2 = 2

y = 2-(1/2)

y = 3/2
