In order to find the probability of drawing a marble that is NOT BLUE, we must find the ratio of non-blue marbles to the total amount of marbles
Let's count how many marbles total there are first
8 red + 3 blue + 1 green = 12 marbles total
Now, how many marbles are there that <u>ARE NOT BLUE </u>
8 red + 1 green = 9 marbles <u>THAT ARE NOT BLUE </u>
Now<em> let's create a ratio</em> to find a probility
9/12
This can be simplified to 3/4 by taking out the common factor of 3
Your answer is D! "three-fourths"
Answer:
y = - 5x - 1
Step-by-step explanation:
The first thing to do (always) is pay attention to x =0. That at least gives you a partial answer. y = y' - 1. when you put 0 in for whatever y' is you get 0. What about the other numbers? How did they come about.
We have another clue. Whenever you put in a positive number for x, you get a negative answer for y. That's interesting. So y' has a minus sign associated with it.
y = -ax - 1 Make a>0 so there is only 1 minus sign. x cannot have an even power, because an even power would make everything positive except the -1.
So we'll start with y= - ax - 1 We'll also make the assumption that a = 1
y = - x - 1 That won't work. a >1 otherwise x = 2 won't give - 11
y = -ax - 1
let x = 2
let y = - 11 Solve for a
y = - ax - 1
- 11 = -a*-2 - 1 add 1 to both sides
-11 + 1 = - a(-2) - 1 + 1
- 10 = -2a Divide by - 2
- 10/-2 = -2a/-2
a = 5
Answer: y = - 5x - 1
All triangles have a measurement of 180 degrees. Therefore, we can use this information to make an equation to find the value of angle B.
Angle B = 180 - (28 + 36)
Angle B = 180 - 64
Angle B = 116
So, angle B is equal to 116 degrees.
