Answer:

Step-by-step explanation:

The white area is the area of the circle minus the area of the triangle.

Aw=pr^2-hb/2

Aw=p4^2-6.5(6)/2

Aw=16p-19.5

The probability of selecting the white area is the white area divided by the area of the circle

P(W)=(16p-19.5)/(16p), p=3.14

P(W)=0.61

Answer:

L = 12 inches

Step-by-step explanation:

Using the Pythagorean theorem:

15² - 9² = L²

L² = 144

L = 12 inches

Answer:

The first option

Step-by-step explanation:

Since all sides are obtuse, its an obtuse triangle.

Answer:

Undefined

Step-by-step explanation:

[tex]\boxed{slope = \frac{y1 - y2}{x1 - x2} }[/tex]

☆ (x₁, y₁) is the first coordinate and (x₂, y₂) is the second coordinate.

Slope of the line

[tex] =\frac{ - 4 - ( - 4)}{7 - 5} \\ =\frac{ - 4 + 4}{2} \\ = \frac{0}{2} \\ (undefined)[/tex]

Thus, the slope of the line is undefined.

(Since 2 cannot be divided by zero)

Notice that the two coordinates have the same y- coordinate of -4. This means that the line is a vertical line. Vertical lines have undefined slopes.

Answer:   The three numbers are 10, 11, and 12.

10+11+12 = 33

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

Work Shown:

Each is a positive whole number

Add them up and set the result equal to 33. Solve for x.

(x) + (x+1) + (x+2) = 33

3x+3 = 33

3x+3-3 = 33-3 .... subtract 3 from both sides

3x = 30

3x/3 = 30/3 ..... divide both sides by 3

x = 10

x+1 = 10+1 = 11

x+2 = 10+2 = 12

Note how 10+11+12 = 33 to help confirm our answer.

El área de la finca que está sembrada por café es 360 m².

Step-by-step explanation:

La finca de Federico tiene tiene un área de 576 m². [tex]\frac{3}{8}[/tex] de la finca están sembrados de naranjas. Entonces, el área de la finca que está sembrada por naranjas se calcula mediante:

576 m²* [tex]\frac{3}{8}[/tex] = 216 m²

Sabiendo que el resto de la finca esta sembrada de café, esta área se calcula mediante la diferencia del área total de la finca y el área sembrada por naranjas:

576 m² - 216 m²= 360 m²

El área de la finca que está sembrada por café es 360 m².

Answer: 2 independent sample test of proportions

Step-by-step explanation:

The teo independent sample test of proportion is also referred to as the two proportion z-test and it simply allows the researcher to compare the two proportions in order to ascertain if they're the same or not.

In this case, the null hypothesis will be that that the proportions given in the research are the same while the alternate hypothesis will be that there is a difference between the proportions given.

The kind of analysis that would be most adequate for the given study:

Test of 2 Independent Proportions.

The test of two independent proportions is characterized as the method of study in which samples are opted randomly and allowed to remain independent.

In such a study, a minimum of 5 failures and successes are considered to reach a conclusion.

In the given situation, the samples of males and females are random and permitted to stay free("continue after the mission") and evaluated after a time to take the deduction.

Answer:

i think is number 2

Given:

The given figure represents the original parallelogram and the reduction.

To find:

The length of side A in the new parallelogram.

Solution:

We know that the original figure is always similar to its reduction. So, both parallelograms are similar to each other.

The corresponding sides of similar figures are proportional.

[tex]\dfrac{45}{18}=\dfrac{5}{A}[/tex]

[tex]45\times A=5\times 18[/tex]

[tex]45A=90[/tex]

Divide both sides by 45.

[tex]A=\dfrac{90}{45}[/tex]

[tex]A=2[/tex]

The length of side A in the new parallelogram is 2 cm. Therefore, the correct option is A.

Step-by-step explanation:

60% = 0.6

15% = 0.15

10 = 0.15

Answer:

24

Step-by-step explanation:

Let x represent total number of vehicles

Let T represent number of trucks

Let V represent number of vans

Let B represent number of buses

Convert percent's to decimals:

60% = 0.6

15% = 0.15

Set up equations:

T = 0.6x

V= 0.15x

B= (1 - 0.6 - 0.15)x

For buses, the remaining portion of the 100% of vehicles is 100% -60% -15%

Since we know there are 10 buses, set B=10

B= (1 - 0.6 - 0.15)x

10= (1 - 0.6 - 0.15)x

10= 0.25 x

Divide both sides by 0.25 so that we get:

10/0.25 = x

x= 40

We now know there are 40 vehicles present.  To find the number of trucks, we take 60% of the total number of vehicles

T = 0.6x

T= 0.6 (40)

T= 24

Therefore there are 24 trucks.

Answer:

90 degrees

Step-by-step explanation:

Complete question

A coffee is sitting on Mr. Hunt's desk cooling. It cools according to the function T=70(0.80)^x+20, where x is the time in minutes and T is the temperature in degree Celsius. WHAT IS THE INITIAL temperature of the coffee

The initial temperature occurs at x = 0

Substitute x = 0 into the expression;

T=70(0.80)^x+20

T =70(0.80)^0+20

Since any value raise to power of zero is 1, hence;

T = 70(1)+20

T = 70+20

T = 90 degree Celsius

Hence the initial temperature of the coffee is 90 degrees

The initial temperature of the coffee is 90 degrees.

The function is represented as:

[tex]\mathbf{T = 70(0.80)^x + 20}[/tex]

At the initial temperature, x = 0.

So, we have:

[tex]\mathbf{T = 70(0.80)^0 + 20}[/tex]

Expand

[tex]\mathbf{T = 70 \times 1 + 20}[/tex]

Multiply

[tex]\mathbf{T = 70 + 20}[/tex]

Add

[tex]\mathbf{T = 90}[/tex]

Hence, the initial temperature of the coffee is 90 degrees.

The required area covered by 10 tiles having dimensions 3/2 feet by 3/2 feet.

The square is a 4 sided figure, each side of the square is equal and make a right angle.

The area of square having sided a unit can be given by a² square unit.

Given that,

The length of tile = 3/2 feet,

And the width of tile = 3/2 feet.

Total number of tiles = 10.

The tiles are in square shape.

The area of one tile = 3/2 x 3 / 2 = 9 / 4 square feet

The area of 10 tiles = 9/4 x 10 = 22.5 square feet.

Answer:

Answer 1. 3in

Answer 2. 0.875in

Answer 3. 26 miles

Answer 4. 7.67in

Step-by-step explanation:

Answer 1. We know that 2 feet in real life is going to equal 1 inch, so since the person is 6 feet, we divide that by 2 to get 3. So the action figure is going to be 3in.

Answer 2. In this case, we see that 1 foot is equal to four inches. That must mean that 1 inch is equal to a quarter foot. So we just multiply

0.25 x 3.5 = 0.875

The length is 0.875 feet

Answer 3.

We know that 1 inch = 6.5 miles, and there are 4 inches on the map, so we have to multiply 6.5 x 4 to find out how many miles there is.

Answer 4.

To find this one out, we have to divide 9 into 69. That gives us 7.67. So 69 nautical miles would be equal to 7.67 inches on the map
