referring to the table below, are the events is female and owns a dog independent?
Answer:
No
Step-by-step explanation:
They are independent iff:
P(F & D) = P(F) × P(D)
15.278/100 = (55/100) × (27.778/100)
0.15278 = 0.125279 (false)

Given the function g(x) = 7x - 14 find its inverse function.
Answer:
The inverse is 1/7x +2
Step-by-step explanation:
y = 7x - 14
Exchange x and y
x = 7y-14
Solve for y
Add 14 to each side
x+14 = 7y-14+14
x+14 = 7y
Divide each side by 7
(x+14)/7 = 7y/7
1/7x +2 = y
The inverse is 1/7x +2
Answer:
g^-1(x)=x/7+2
Step-by-step explanation:
y=7x-14
7y-14=x
7y=x+14
y=1/7x+2
g^-1(x)=x/7+2
A rectangle has a height of xxx and a width of 7x-47x−47, x, minus, 4.
Express the area of the entire rectangle.
Answer:
[tex]7x^{2}-4x[/tex]
Step-by-step explanation:
Area of a rectangle is expressed as Length * Width
Given the length/height = x
width = 7x-4
Area of the rectangle = [tex]x(7x-4)[/tex]
On opening the bracket;
Area of the rectangle = [tex]7x^{2}-4x[/tex]

Consider the two similar cylinders. The heights of both cylinders are given, along with the diameter of the smaller cylinder. What is the diameter
of the larger cylinder?
48 in
32 in
12 in
Figures not drawn to scale
А
28 inches
B
20 inches
18 inches
Answer:
18 inches
Step-by-step explanation:
Given: The heights of both cylinders are 48 inches and 32 inches. Diameter of the larger cylinder is 12 inches
To find: diameter of the larger cylinder
Solution:
Height of the larger cylinder (H) = 48 inches
Height of the smaller cylinder (h) = 32 inches
Diameter of the smaller cylinder (d) = 12 inches
Radius of the smaller cylinder (r) = d/2 =12/ 2= 6 inches
As two cylinders are similar, their heights and radii are proportional.
[tex]\frac{r}{h}=\frac{R}{H}\\\frac{6}{32}=\frac{R}{48}\\R=\frac{6}{32}\times 48=9\,\,inches[/tex]
Diameter of the larger cylinder = 2R = 2(9) = 18 inches
A plane is flying at an elevation of 25000feet. It is within the sight of the airport and the pilot finds that the angle of depression to the airport is 14 degrees. Find the diagonal distance between the plane and the base of the airport.
Answer:
The distance between the plane and the base of the airport = 103339.14 ft
Step-by-step explanation:
Consider the diagram attached.
We can notice that the a triangle (ABC) can be formed between the plane, the airport, and a vertical line drawn from the ground to the plane showing its altitude.
The angle of depression is 14 degrees. This means that angle BAC is 90 - 14 = 76 degrees.
From triangle laws, we will have that [tex]cos 76 = \frac{Altitude}{AC}[/tex]
[tex]AC = \frac{25000}{(cos 76)} = 103339.14 ft[/tex]
Hence, the distance between the plane and the base of the airport = 103339.14 ft
The diagonal distance between the plane and the base of the airport is 103339.14 ft.
This situation forms a right angle triangle.
The plane is flying at an elevation of 25000 ft.
The elevation is the height or opposite side of the triangle.
The diagonal distance between the plane and the base of the airport is the hypotenuse of the triangle.
Therefore, using trigonometric ratio,
sin 14° = opposite / hypotenuse
sin 14° = 25000 / d
d = 25000 / sin 14
d = 25000 / 0.2419218956
d = 103339.137361 ft
Therefore, the diagonal between the plane and the base of the airport is 103339.14 ft.

Dan buys a car for £900.

How much will it be worth in 4 years?
Give your answer to the nearest penny where appropriate.
$857.58 is the price of car after 4 years.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given,
Dan buys a car for £900.
It depreciates at a rate of 1.2% per year
We need to find the cost of car after 4 years.
1.2/100=0.012
Now multiply 0.012 with 900
10.8
So for first year it will be 900-10.8=889.2
0.012×889.2
10.67
For second year 889.2-10.67=878.53
0.012×878.53=10.54
For third year 878.53-10.54=867.99
0.012×867.99=10.41
For fourth year 867.99-10.41=857.58
Hence, after 4 years the price of car will be 857.58.

Answer:
27π
Step-by-step explanation:
First, find the area as though the circle were complete.
A = πr²
A = π(6)²
A = 36π
Now, if you look at the diagram, you can see that the chunk missing forms a 90 degree angle. In a circle, there is 360 degrees in total. This means that only 3/4 of the circle is left. Multiply the area by 3/4.
36π × 3/4 = 27π
The area is 27π.

Step-by-step explanation:

Step-by-step explanation:
Let pencils be denoted using 'x', and notebooks 'y'.
4x+12y = 60, 14x+7y=70
Let us use the method of elimination. However, neither variable has the same coefficient, so let us multiply the first equation using 7, and the second using 2.
7(4x+12y = 60) => 28x+84y=420
2(14x+7y=70) => 28x+14y=140
Let us subtract the second equation from the first. This eliminates the first variable x, and gives the equation 70y=280
Dividing either side of the equation by 70, we get y=4.
If we substitute (plug in) y=4 for the first equation we get x=3

Complete question:
The park closes at 2:30 P.M. There is a 15−minute break between each game played at the park, and each game takes the same amount of time as Hamid's soccer game. How many more games can be played before the park closes? Hamid's soccer game time is 7:00 to 9:15
Answer:
2 more games can be played before the park closes.
Step-by-step explanation:
Given that Hamid's soccer game time is from 7:00 to 9:15 and there's a 15 minute break between games played, the next game time would be: 9:15 + 15 = 9:30
The time for each game would be calculated as:
stop time - start time = 9:15 - 7:00 = 2:15.
Thus, each game time = 2hrs 15mins
The next game time would be:
9:30 + 2:15 = 11:45
This means the next game would be from 9:30 to 11:45
After this, there would be another game(a second extra game) since the park closes at 2:30PM.
Therefore, the next game time would be:
11:45 + 15 mins break = 12:00
The game duration =
12:00 + 2hrs 15 mins = 14:15 or 2:15PM
Considering the fact that the park closes by 2:30 PM, 2 more games will be played.

complete the table of values fory=2x^2+x
Complete question:
y = 2x² + 2x - 3
x = -2 -1 0 1 2
Answer:
Complete table of values
x: -2 -1 0 1 2
y: 1 -3 -3 1 9
Step-by-step explanation:
Given;
y = 2x² + 2x - 3
To complete the table of values of the equation above, we substitute the value of x into the given equation and solve for y.
when, x = -2
y = 2(-2)² + 2(-2) - 3
y = 8 - 4 - 3
y = 1
when x = -1
y = 2(-1)² + 2(-1) - 3
y = 2 - 2 - 3
y = -3
when x = 0
y = 2(0)² + 2(0) - 3
y = 0 - 0 - 3
y = -3
when x = 1
y = 2(1)² + 2(1) - 3
y = 2 + 2 - 3
y = 1
when x = 2
y = 2(2)² + 2(2) - 3
y = 8 + 4 - 3
y = 9
Complete table
x: -2 -1 0 1 2
y: 1 -3 -3 1 9
