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.

Answer:
What is the constant variation of Y =- 2 3x?
The constant of variation, k , is 23 .
Step-by-step explanation:
When x is zero in a direct variation equation y will also be zero. That means that the y-intercept of all direct variation equations is always zero.
Answer:
y+2 = -1 ( x+4)
Step-by-step explanation:
The y intercept is 2
The slope is found by using two point
( 0,2) and ( 2,0)
m = (y2-y1)/(x2-1)
= ( 0-2)/(2-0)
= -2/2
= -1
The slope is -1 and the y intercept is 2
Using point slope form
y -y1 = m(x-x1) where m is the slope and ( x1,y1) is a point on the line
y-y1 = -1(x-x1)
It appears that we are using y1 = -2 so x = 4
y - -2 = -1( x -4)
y+2 = -1 ( x+4)
Answer:
G(t) = 35*sin(10*t) + 35
Step-by-step explanation:
In the figure attached, the question is shown. The function has the form:
G(t) = a*sin(b*t) + d
We know that at t = 0, G(t) = 35. Replacing into the equation:
35 = a*sin(b*0) + d
d = 35
We know that at t = π/20, G(t) = 70, which is a maximum. The maximum is reached when sin(b*t) = 1, replacing into the equation:
70 = a*1 + 35
a = 35
If sin(b*t) = 1, then:
b*t = π/2
b*π/20 = π/2
b = 20/2 = 10
