The slope intercept form of a straight line is

y = mx + c where m = slope and c = y-intercept

so here we have c = 3.
and
y = mx + 3
WE can find the slope  m as follows
m  = (5-3) / ( 4 - 0) = 2/4 = 1/2
So our equation is

y = 1/2 x + 3
or we could write it as
2y = x + 6
or
-x + 2y = 6  (standard form)

Two things to note;

1. Since there's only one 2 or hearts and one 3 of clubs

2. The first card is replaced after it's drawn

Probability of 2 of hearts = 1/52

Probability of 3 of clubs = 1/52

They both have the same probability of being drawn.

Here is a rectangle which has a width of x cm. x cm
miskamm [114]

Answer:

278.25 cm2

Step-by-step explanation:

If the width of the rectangle is x (cm), as the length is 8cm longer, so that the length of the rectangle is: x + 8 (cm).

In the attached image, we can see the length of each side. Total length of the sides are 90 cm.

=> (x + x + 8) + x + 8 + (x+8) + (x + x + 8) + x + 8 + (x +8) = 90

=> 8x + 48 = 90

=> 8x = 90 - 48 = 42

=> x =42/8 = 5.25 (cm)

=> The width of the rectangle is 5.25cm

=> The length of the rectangle is: 5.25 + 8 = 13.25 cm

=> The area of one rectangle is: Length x Width = 5.25 x 13.25 = 69.5625 cm2

As the 8-sided shape is made from 4 rectangles, so that:

Area of 8 sided shape = 4 x Area of the rectangle = 4 x 69.5625 = 278.25 cm2
