Answer: 23/72

Step-by-step explanation:

180 degrees = half of circle

5 degrees = 1/72 of circle

5 degrees times 23 = 115 degrees

1/36*23 = 23/72

Answer:

23/72 of a circle

Step-by-step explanation:

The cost of an apple is $1 and the cost of an orange is $2

From the question, we have the following parameters that can be used in our computation:

x = apples

y = oranges

Using the above as a guide, we have the following:

5x + 2y = 9

7x + 3y = 13

Multiply (1) by 3 and (2) by 2

15x + 6y = 27

14x + 6y = 26

Subtract

x = 1

So, we have

5(1) + 2y = 9

This gives

y = 2

Hence, the cost of orange is $2

The Z score associated with our observation is 2.45. This means that our observed value is 2.45 standard deviations away from the expected value.

2.45

Z score = (Observed value - Expected value) / Standard Deviation

Z score = (95 - 85) / √(85*(1-85)/30)

Z score = 2.45

We can calculate the Z score associated with our observation by taking the observed value, 95%, and subtracting the expected value, 85%, and dividing this by the standard deviation. To calculate the standard deviation, we use the formula: √(expected value*(1-expected value)/sample size). In this case, 85*(1-85)/30. The Z score associated with our observation is 2.45. This means that our observed value is 2.45 standard deviations away from the expected value.

To find out how much each ticket costs, we can use this equation:

Total cost ÷ Number of tickets = Price of each ticket

Inserting the numbers into the equation would look like this:

To check our work, we can multiply the number of tickets by the price of each ticket to see if it matches up to the correct total price.

Therefore, each ticket costs $8.

Answer:

Genesis has 126 different outfits to choose from.

Step-by-step explanation:

To calculate the total number of different outfits Genesis can choose, we need to multiply the number of choices available for each article of clothing. So we have:

7 choices for pants

2 choices for t-shirts

3 choices for sweaters or hoodies

3 choices for shoes

To find the total number of outfits, we multiply the number of choices for each category:

7 x 2 x 3 x 3 = 126

Therefore, Genesis has 126 different outfits to choose from.

126 different combination does Genesis have to choose.

We have,

Pants = 7

T shirts = 2

Sweaters or Hoodies = 3

Shoes = 3

So, the number of different combination is

= C(7, 1) x C( 2, 1) x C(3, 1) x C(3, 1)

= 7 x 2 x 3 x 3

= 126 ways

To find the probability of randomly withdrawing 5 jellybeans such that at least 2 are red, we need to find the total number of ways to select 5 jellybeans from the bag and then find the number of ways to select 2 or more red jellybeans.

Let's first find the total number of ways to select 5 jellybeans from the bag:

Total number of jellybeans = 4 red + 7 green = 11 jellybeans

Number of ways to select 5 jellybeans from 11 = 11 choose 5 = 462

Next, we need to find the number of ways to select 2 or more red jellybeans:

Number of ways to select 2 red jellybeans = 4 choose 2 = 6

Number of ways to select 3 red jellybeans = 4 choose 3 = 4

Number of ways to select 4 red jellybeans = 4 choose 4 = 1

Total number of ways to select 2 or more red jellybeans = 6 + 4 + 1 = 11

The desired probability is the ratio of the number of favorable outcomes (selecting 2 or more red jellybeans) to the total number of possible outcomes (selecting 5 jellybeans):

P(at least 2 red) = 11/462 = 11/462 = 0.0239 or 2.39%

So, the probability of randomly withdrawing 5 jellybeans such that at least 2 are red is 2.39%.

sin70 = x/3.6

x = 3.6sin70

x = 3.4

Answer:

x = 3.4

Step-by-step explanation:

As the given triangle is a right triangle we can use trigonometric ratios to solve for x.

[tex]\boxed{\begin{minipage}{9.4 cm}\underline{Trigonometric ratios} \\\\$\sf \sin(\theta)=\dfrac{O}{H}\quad\cos(\theta)=\dfrac{A}{H}\quad\tan(\theta)=\dfrac{O}{A}$\\\\where:\\ \phantom{ww}$\bullet$ $\theta$ is the angle. \\ \phantom{ww}$\bullet$ $\sf O$ is the side opposite the angle. \\\phantom{ww}$\bullet$ $\sf A$ is the side adjacent the angle. \\\phantom{ww}$\bullet$ $\sf H$ is the hypotenuse (the side opposite the right angle). \\\end{minipage}}[/tex]

From inspection of the triangle:

As we know the angle and the hypotenuse, and wish to find the side opposite the angle, substitute the values into the sine ratio and solve for x:

[tex]\implies \sin(70^{\circ})=\dfrac{x}{3.6}[/tex]

[tex]\implies x=3.6\sin(70^{\circ})[/tex]

[tex]\implies x=3.382893...[/tex]

[tex]\implies x=3.4\; \sf (nearest\;tenth)[/tex]

Therefore, x = 3.4 to the nearest tenth.

The rectangular blocks with the measure of 7 cm by 8 cm by 9 cm will not fit in the smallest cylindrical cup with the radius of 5cm.

Rectangular block with the least dimensions, 7cm by 8cm side.

Circle with radius r is x² + y² = r²

∴ x² + y² = 5² or x² + y² = 25

Draw the area of the block using the coordinates (3.5,4) ; (-3.5,4) ; (-3.5,-4) and (3.5,-4)

Its observed that the block cannot fit inside the cup. We can confirm this if

y >4 when x = 3.5

3.5² + y² = 25

12.25 + y² = 25

y² = 12.75

taking positive square root, y≈3.57

Since this is <4, the block cannot fit the 5 cm radius cup.

equation for the cup with r = 6cm,

x² + y² = 6² or x² + y² = 36

Draw the area of the block using the coordinates (3.5,4) ; (-3.5,4) ; (-3.5,-4) and (3.5,-4)

it is observed the block will fit inside the cup as y>4 when x = 3.5

3.5² + y² = 36

12.25 + y² = 36

y² = 23.75

taking positive square roots, y≈4.87

Since this is >4, the block can fit the 6 cm radius cup.

equation for the cup with r = 7cm,

x² + y² = 7² or x² + y² = 49

Draw the area of the block using the coordinates (3.5,4) ; (-3.5,4) ; (-3.5,-4) and (3.5,-4)

it is observed the block will fit inside the cup as y>4 when x = 3.5

3.5² + y² = 49

12.25 + y² = 49

y² = 36.75

taking positive square roots, y≈6.06

Since this is >4, the block can fit the 7 cm radius cup.

Answer:

To calculate the total amount of carbon dioxide emitted over the course of 15 years, we can start with the initial amount of 92,000 kilotons and multiply by 0.95 (the reduction factor) each year.

Step-by-step explanation:

Year 1: 92,000 kilotons

Year 2: 92,000 * 0.95 = 87,400 kilotons

Year 3: 87,400 * 0.95 = 82,990 kilotons

and so on, until year 15.

To find the total amount of carbon dioxide emitted over the course of 15 years, we need to sum up the emissions for each year:

92,000 + 87,400 + 82,990 + ... + (92,000 * 0.95^14) = 92,000 * (1 + 0.95 + 0.95^2 + ... + 0.95^14)

This is a finite geometric series and can be calculated using the formula for the sum of a finite geometric series:

S = a * (1 - r^n) / (1 - r),

where S is the sum, a is the first term, r is the common ratio, and n is the number of terms.

For this series, a = 92,000, r = 0.95, and n = 15. Plugging these values into the formula, we get:

S = 92,000 * (1 - 0.95^15) / (1 - 0.95)

S = 92,000 * (1 - 0.556774) / 0.05

S = 92,000 * 0.443226 / 0.05

S = 92,000 * 8.86452

S = 814,178.24 kilotons

Rounding to the nearest whole number, the country would emit 814,178 kilotons of carbon dioxide over the course of 15 years.

The given expression (2x^3 + 2)/(x^3 - 2) can be written as a composition of two non-identity functions as follows:

Let f(x) = 2x^3 + 2 and g(x) = x^3 - 2.

Then, the expression can be written as:

f(x)/g(x) = (2x^3 + 2)/(x^3 - 2)

So, the expression is a composition of the two non-identity functions f and g, written as:

h(x) = f(g(x)) = (2x^3 + 2)/(x^3 - 2)
