The theoretical probability of spinning an odd number is equal to 5/9.

The experimental probability is equal to 3/5.

The theoretical probability of is greater than the experimental probability.

The sample space is H1 T1 H2 T2 H3 T3 H4 T4 H5 T5 H6 T6.

The different combo meals that are possible is 90.

The experiment probability that the pea pod has 9 peas in it is 45%.

Probability is used to determine how likely it is that an event would happen. Experimental probability is based on the result of an experiment that has been carried out multiples times

The theoretical probability of spinning an odd number = odd numbers between 1 and 9 / 9 = 5/9

The experimental probability = number of odd number / sample space

6/10 = 3/5

The different combo meals possible = 6 x 5 x 3 = 90

The experiment probability that the pea pod has 9 peas in it = number of pods with 9 peas / total number of peas

(18/40) x 100 = 45%

The Cost of operating the theater if there are 100 people at a show is 20,000Rs.

The theater is a place where the movies are shown on big screens and Speakers are used for the clear audio of the movie.

In a theater, there will be 3 to 4 shows for a movie or a different movie.

Theater can consist of 250 - 300 seats and can cost up to 250rs for a seat.

The average cost of a college education has gone up dramatically.

Consider a ticket cost of 200rs.

For 100 people in a show,

Cost = 200 × 100

Cost = 20,000.

Hence the cost of operating a theater if there are 100 people at a show is 20,000Rs.

Answer:

-4√5/9.

Step-by-step explanation:

if cos x = -2/3 then sin x = √(1 - (-2/3)^2)

= √(5/9)

= √5/3.

(As x is in quadrant 2 sin x is positive).

So:

sin2x = 2 sin x cos x

         = 2 * √5/3 * -2/3

          =  -4/3 * √5/3

          =  -4√5/9.

The sample size for part (a) is 540, and the sample size for part (b) is 543 if the margin of error is 0.05.

It is defined as an error that provides an estimate of the percentage of errors in real statistical data.

The formula for finding the MOE:

[tex]\rm MOE = X \times \dfrac{s}{\sqrt{n}}[/tex]

Where   Z is the z-score at the confidence interval

           s is the standard deviation

           n is the number of samples.

We know:

[tex]\rm MOE =Z \times\sqrt{ \dfrac{pq}{n}}[/tex]

We have MOE = 0.05, p = 46% = 0.46,

q = 1-p = 1-0.46 = 0.54

Z at 0.02(because 98% level of confidence) = 2.33

Plug this value in the formula we get:

[tex]0.05=2.33\times \sqrt{\dfrac{0.46\times 0.54}{n}}[/tex]

After solving:

n = 539.41 ≈ 540

If no estimate is given:

p = 0.5 and q = 0.5

[tex]0.05=2.33\sqrt{\dfrac{0.5\times 0.5}{n}}[/tex]

n = 542.89 ≈ 543

Thus, the sample size for part (a) is 540, and the sample size for part (b) is 543 if the margin of error is 0.05.

Answer:

The selling price is $3,125

Step-by-step explanation:

25% of 2500 is 2500 x 0.25 = 625

You will be adding the 25% gain to cost price to find the new price

2500 + 625 = 3125

Answer:

3125

Step-by-step explanation:

from the question,

25% simply means 25/100= 0.25

25% of 2500= 0.25×2500= 625

gain= 625

selling price= 625+2500= 3125

Step-by-step explanation:

There are a total of 11 chocolates in the box.

The probability of picking milk chocolate first is 4/11.

Now that you eat one, there are 10 chocolates in the box.

The probability of picking a dark chocolate second is 7/10.

This is a compound probability problem, so multiply the two probabilities together.

4/11 x 7/10 = 28/110

Answer:

D 36.6

Step-by-step explanation:

Here, there is a triangle inscribed inside of a semicircle where the triangle is unshaded and the remained of the semicircle is shaded and we want to find the area of that shaded untouched area of the semicircle.
To do so we must find the area of the two shapes individually and then subtract the area of the triangle from the area of the semi circle as the triangle is what is uncovering the semicircle.

Finding the area of the semicircle

Area of a semicircle = (πr²)/2 where r = radius

Here we are given the diameter of the semicircle which is 13cm. We can easily convert the diameter to radius by dividing it by 2 as the radius is equal to half the diameter

Radius = 1/2 diameter , so radius = 13 / 2 = 6.5cm

We have A = πr²/2

==> plug in radius or r = 6.5

A = π(6.5)²/2

==> simplify exponent

A = π(42.25)/2

==> multiply π and 42.25 ( note that π = 3.14 approximately

A = 132.665/2

==> divide 132.665 by 2

A = 66.366

So the area of the semicircle is 66.366cm²

Finding the area of the triangle

The area of a triangle can be calculated by dividing the product of the base length and height ( formula = bh / 2 where b = base length and h = height )

Here the base length appears to be 5cm and the height appears to be 12cm so b = 5 and h = 12

So we have A = bh/2

==> plug in b = 5 and h = 12

A = (12)(5)/2

==> multiply 12 and 5

A = 60 / 2

==> divide 60 by 2

A = 30

So the area of the triangle is 30cm²

Subtracting the area of the triangle from the area of the semicircle

Finally to find the area of the shaded region we subtract the area of the triangle from the area of the semicircle

We have area of triangle = 30cm² and area of semicircle = 66.366

So area of shaded region = 66.366 - 30 = 36.366

Step-by-step explanation:

Area of circle - area of square

Answers:

The "square feet" portions are already handled by your teacher, so you'll just type in the numbers only.

======================================================

Explanation:

The formula for the area of a circle is

A = pi*r^2

We replace pi with its approximation 3.14, and plug in the radius r = 8.1 to get the following approximate area:

A = 3.14*(8.1)^2

A = 206.0154

A = 206.02 which is the answer to the first box

--------------------------

The unshaded region is a square of side length 11.5 ft

Its area must be (11.5)^2 = 132.25 square feet

--------------------------

Subtract the results of the previous boxes to get the shaded area.

206.02 - 132.25 = 73.77

The table is a linear function, and the rule for the input/output table is f(x) = 1 + 3x

From the table, we can see that:

The output of the table  is 1 more than 3 times the input

If the input is x, then the output y is:

y = 1 +3 * x

Evaluate

y = 1 + 3x

Hence, the rule for the input/output table is f(x) = 1 + 3x
