Answer:
13.89%
Step-by-step explanation:
First lets find all possibilities of two dice being thrown, we can do this by finding a simple dice chart online (I attached an image of one to help.)
There are 36 possibilities, and we need to find how often the two dice add together to equal eight. 6+2=8, 5+3=8, etc.
There are five 5 total times that two dice can equal eight. so 5 out of 36 times we roll two dice we'll get eight.
Type that into the ol' handy dandy calculator and we've got 0.1388888889. So... a lot of 8's, we don't need that many and we just can't have an answer with that many.
To make that number into a percentage we have to move the dot two spaces over, and round to the thousandths place (two numbers).
This would give us 13.89%, our final answer.
Hope this helped!
Answer:
(a) (-1/4,0)
(b) k = (10-c)/2
Step-by-step explanation:
(a) A point passing through the y-axis is the same as finding the y-intercept.
[Move terms to right-hand side; y = mx + b form]
y = 4x + 1
[Find x, when y = 0]
0 = 4x + 1
-1 = 4x
-1/4 = x
At x = -1/4, y = 0 therefore the point: (-1/4,0) crosses the y-axis.
(b) To find the value of k in (k,10), we need to find x. Given y= 10 x=k c=constant
[Find x by plugging in known values]
Using y = 2x + c,
10 = 2k + c
10 - c = 2k
(10-c)/2 = k
Answer: y = x -1
reasoning: the slope is 1 because the rise/run = 1/1, which simplifies to 1.
the y intercept is -1 because the line passes through the y axis at -1.

Y=-4X+1 the equation can be anything without a specific x-in’t
