Graph the line with slope 1 passing through the point (5,1).

ser-zykov [4K]

Answer:

A line is defined by two points. What you need is to find coordinates of another point on the line, and then just draw a line between that point and point (5,1)

Step-by-step explanation:

The general eqation of the line is y=ax+b

We know that the slope is one, which makes a=1

We also know that when x=5, then y = 1

Let's plug it in:

1=1*5+b

1=5+b

b= -4

So the line equation is y=x-4

Let's pick x = 1 (you can pick any x, and just solve to find the y coordinate of another point.

So, when x = 1, y = 1 - 4 = -3

Now draw a line through points (5,1) and (1,-3)

A gambler in Las Vegas is cutting a deck of cards for $1,000. What is the probability that the card for the gambler will be the

White raven [17]

Answer:

a. 3/13 or 23.08%

b. 1/13 or 7.69%

c. 1/4 or 25.00%

d. 1/52 or 1.92%

Step-by-step explanation:

Number of cards in a deck = 52

a. A face card

Considering there are four suits and each suit has three different face cards, the probability that the card is a cafe card is:

$P_{F} =\frac{3*4}{52}\\ P_{F} =\frac{3}{13}$

b. A queen

There are 4 queens in the deck, on of each suit, thus the probability of getting a queen is:

$P_{Q} =\frac{4}{52}\\ P_{Q} =\frac{1}{13}$

c. A spade

There are four suits with the same number of cards in a deck, therefore, the probability of getting a spade is:

$P_{S} =\frac{1}{4}$

d. A jack of spades

Since there are no repeated cards, there is only one jack of spades in a 52 cards deck:

$P_{J+S} =\frac{1}{52}$
