(B)40
(C)48
(D) 126​

Answer:

0.1

Step-by-step explanation:

If A and B are independent, hence P(A and B) = P(A)P(B)

Given the following

P(A and B) = 0.034

P(A) = 0.34

Required

P(B)

Substitute into the given formula;

P(B) =P(A and B)/P(A)

P(B) = 0.034/0.34

P(B) = 0.1

Hence the value of P(B) is 0.1

X in (-oo:+oo)

X^2 = 1/100 // - 1/100

X^2-(1/100) = 0

X^2-1/100 = 0

1*X^2 = 1/100 // : 1

X^2 = 1/100

X^2 = 1/100 // ^ 1/2

abs(X) = 1/10

X = 1/10 or X = -1/10

X in { 1/10, -1/10 }

Answer:

The answer is "Option C".

Step-by-step explanation:

The graph of the even function will have both ends pointed in the same direction, while the graph of the odd function will have both ends pointed inside the reverse way. Furthermore, as the y-axis approaches, and also regular expression graph becomes symmetric. The graph of an unusual function, on either hand, is symmetric around the origin and also has rotational symmetry around the origin. They could see that the graph of function g meets a function requirement by looking at it. That graph of function f, but on the other hand, is not symmetric about its y-axis, implying that function f is not even. As both a result, g is a function that is even.

Answer:

Only function g is given

Answer:

The dog has 1357.5 square feet of running space.

Step-by-step explanation:

48 feet is the diameter of the circle in which the dog can run, minus 1/4 of the total circle (assuming the dog can not run through walls).

The formula of how to find the area of a circle is...

A =  π r²

A stands for area, pi(π) is 3.14, and r means radius.

Radius is half of the diameter, so the radius would be 24 feet. Let's plug those numbers into the formula:

A = π x 24²

A = π x 576

A = 1809.56 square feet

Now, we have to subtract 1/4 of 1810 (rounded up).

1810 times 0.75 = 1357.5 feet.

I hope this helps you! :-)

Answer:

623

Step-by-step explanation:

To find the top area of the square=26-15=11

Area of the top square= 11 x 13= 143

Are of the bottom rectangle=15 x 32= 480

Area of both the shapes combined= 480+143=623

Answer:

just use the photo math app it scans your math problem and it solves it for you and it gives you step by step and explanation

Step-by-step explanation:

go to the Play store then you download the app or wherever you get your apps and then I can't remember from there you might have to create account but it's super easy all you have to do is take a picture and it'll scan it but make sure it's clear it's really easy and it's free photo math is the best

Answer:

a) 0

b)2

Step-by-step explanation:

a) Basically, the question is asking what the x value is when the y value is at 4, which would be 0.

b) Same thing here, but with the x value is when the y value is -2.

Step-by-step explanation:

Radius=EA,AB,DA,CA

diameter=EB

Answer:

64-16pi(not rounded)

64-50.27 = 13.73 (rounded)

Step-by-step explanation:

Square = side^2 - side =8 (4+4)

8*8 = 64

Circle area= pi r^2

16 pi = 50.27

Square-pi*r^2 = answer

64-16pi(not rounded)

64-50.27 = 13.73 (rounded)

Answer:

w=(-5t)+20,000

Step-by-step explanation:

Answer:

Surface area = 2πrh + 2πr^2

= (2 × 22/7 × 5 ×5 + 2×22/7×25)cm^2

= (1100/7+1100/7)cm^2

= 2200/7 = 314.28571) cm^2 (ans)

The graph of the inverse of a function is its reflection across the line y = x

Please find attached the required graph created with MS Excel

The graph of the inverse of a function is reflected over the line y = x

In order to graph the function f⁻¹, either the line y = x is drawn and the points of f⁻¹ are traced by taking equal distance from the line y = x, or the x, and y-coordinates of the f are reversed to get the coordinates of f⁻¹ as follows;

The reflection of the point (x, y) across the line y = x is (y, x)

The vertices of the graph of the function f, staring from the top are;

(5, 6), (3, -3), (-3, -5)

Therefore, we have;

The reflection of the point (5, 6) across the line y = x is (6, 5)

The reflection of the point (3, -3) across the line y = x is (-3, 3)

The reflection of the point (-3, -5) across the line y = x is (-5, -3)

The graph of the function f⁻¹ can be plotted using MS Excel, and the above values, as shown in the attached diagram
