A card is drawn from a deck of 52 cards. What is the probability that it is a 6 or club a ​?

Answers

Answer: 0.3077

Explanation: In a standard deck of cards, there are 52 cards. They are broken down into suits (4 of them: Spades, Hearts, Diamonds, Clubs) of 13 cards each. Each suit has 13 ordinal cards (A, 2 through 10, Jack, Queen, King).

Here we're asked to draw a card at random and find the probability of drawing either a diamond or a 7.

With probability, we look at the fraction of ways we can achieve some condition (the numerator) over the number of ways we can do something (the denominator).

Our denominator here is 52 - the number of cards from which we can pull 1.

Our numerator is both all the diamonds, 13 cards, and all the sevens, 4 cards, but we need to subtract 1 to account for the double counting of the 7 of diamonds.

In all we get: 13+4−1/52=16/52=4/13≈0.3077

Hope this helps... Stay safe and have a great day/night!!!

What is an exponential function?

The function which is in format f(x) =aˣ where a is constant and x is variable,  the domain of this exponential function lies   (-∞, ∞).

Here,
Let
y = abˣ
Substitute the pairs and form two equations,
3 = a   - - - - - - - (1)
75 = ab²   - - - - - (2)

Dividing equation 2 by 1
25 = b²
b = 5
Now,
y = 3{5}ˣ

Thus, the required exponential function is given as y = 3[5]ˣ.

A party planner estimates a party will cost $200 plus $8 for each person attending. What is the y-intercept of the graph of the linear function representing the total cost of the party?

Answers

Answer:

The y intercept is 200

Step-by-step explanation:

Given

Base Cost = 200

Per person =8

Required

Determine the y intercept

First, we need to determine the equation.

The total amount (y) for x persons can be calculated using:

y = Base Cost + Amount per person * x.

This gives

y = 200 + 8 * x

y = 200 + 8x

The general expression of a linear equation is:

y = mx + b

Where b = y intercept

By comparison,

b = 200

Hence, the y intercept is 200

What is the kinetic energy of a bicycle that has a mass of 20 kg and is traveling at a velocity of 10 m/sec? KE= .5 x M x V^2

Answers

You have the formula.
KE= 0.5(20 kg) (10 m/s)^2
KE= 10kg * 100 = 1000 J

The kinetic energy of the bicycle is 100 N

What is kinetic energy?

Kinetic energy is the energy in motion and it is energy doing work. It can be expressed by using the formula:

[tex]\mathbf{K.E = \dfrac{1}{2}\times m \times v^2}[/tex]

where;

m = mass of the object v = velocity of the object

[tex]\mathbf{K.E =0.5 \times 20 \ kg \times 10 \ m/s^2}[/tex]

K.E = 100 N
