Ok so it is a standard deck of 52 cards. Theres 4 suites: Hearts, Spades, Clubs and Diamonds.
In each suite there is 13 cards: Ace, King, Queen, Jack, 10, 9, 8, 7, 6, 5, 4, 3, and 2. The probability of you choosing 5 hearts is most likely to be 5/52.

Answer:

(f+g)(2)  = 4

(f-g)(4) = 8

(f ÷g)(2) = 7

(f x g)(1) = 0

Step-by-step explanation:

We are given these following functions:

f(x) = 2x + 3

g(x) = x - 1

(f+g)(2)

(f+g)(x) = f(x) + g(x) = 2x + 3 + x - 1 = 3x - 2

At x = 2

(f+g)(2) = 3(2) - 2 = 6 - 2 = 4

Then

(f+g)(2)  = 4

(f-g)(4)

(f-g)(x) = f(x) - g(x) = 2x + 3 - (x - 1) = 2x + 3 - x + 1 = x + 4

At x = 4

(f-g)(4) = 4 + 4 = 8

Then

(f-g)(4) = 8

(f ÷g)(2)

(f \div g)(x) = \frac{f(x)}{g(x)} = \frac{2x+3}{x-1}

At x = 2

(f \div g)(2) = \frac{7}{1} = 7

Then

(f ÷g)(2) = 7

(f x g)(1)

(f \times g)(x) = f(x)g(x) = (2x+3)(x-1) = 2x^2 -2x + 3x - 3 = 2x^2 + x - 3

Then

(f \times g)(1) = 2(1)^2 + 1 - 3 = 3 + 1 - 3 = 0

So

(f x g)(1) = 0

Find the volume of a pyramid with a square base, where the perimeter of the base is
grigory [225]

Answer:

90.3125 cm³

Step-by-step explanation:

Since the perimeter of the bottom square is 17, you can divide by four to find out what the lenght of each side is.

17/4=4.25 cm

We know the height of pyramid is 15 cm

The formula for the volume of a square pyramid is

V=a²(h/3)

V=a2(h/3)=4.252·15/3=90.3125 cm³

yaroslaw [1]

Answer:

The answer to your question is Area = 50.27 m²

Step-by-step explanation:

Data

Area = ?

Diameter = 8 m

π = 3.1416

Formula

Area = πr²

Process

1.- Find the length of the radius

   radius = diameter/2

- Substitution

   radius = 8/2

- Result

   radius = 4 m

2.- Find the area of the circle

Area = (3.1416) (4)²

Simplification and result

Area = (3.1416) (16)

Area = 50.27 m²

A spherical ball has a radius of 2 ft what is the volume in cubic feet of the ball
meriva

The Formula for the volume of a sphere is \frac{4}{3} \pi r^3

  • r --> length of radius --> 2ft

 

   <u>Volume</u> = \frac{4}{3} \pi (2)^3 = \frac{4*8}{3} \pi =33.510

The <u>volume is 33.51 cubic feet</u>

<u></u>

Hope that helps!
