Answer:
y = -2x - 9
Step-by-step explanation:
so we have our two points, (-4,-1) and (-8,7) What we need to do to find our slope is y2 - y1 over x2 - x1. Once plugging in the numbers and subtracting it should give you 8/-4. 8 divided by -4 is -2. m = -2. Now to find our "b" we plug in our slope, and plug in one of the two points into the format of y = mx + b.
-1 = -2(-4) + b
multiply -2 and -4
-1 = 8 + b
we subtract 8 from itself and -1
-9 = b
Our equation is y = -2x - 9
Answer:
b= -x+ y/17
Step-by-step explanation:
1. Subtract 17x from both sides of the equation in order to isolate b on one side.
y -17x= 17b
2. Divide every term by 17 in order to isolate b from any coefficients.
y/17 -17x/17 = 17b/17
3. Simplify
b= -x+y/17

Step-by-step explanation:
Ball is tossed 24 times
So the total number of outcomes (tosses) = N = 24
The ball lands in Blue section 3 times out of 24 tosses. So it becomes 3/24
The ball lands in Green section 5 times out of 24 tosses. So it becomes 5/24
The ball lands in Red section 12 times out of 24 tosses. So it becomes 12/24
The ball lands in Yellow section 4 times out of 24 tosses. So it becomes 4/24
Now we have to find how many times will the ball most likely land in the yellow section when it’s tossed 200 times. So the total number of outcomes here is N = 200. The favorable outcome here is that the ball lands in Yellow section. So we use the frequency table above for yellow section:
Yellow / Total tosses
4/24 = x/200
4*200 = 24x
800 = 24 x
24 x = 800
x = 800 / 24
x = 33.3
So ball most likely land in the yellow section 33 times when it’s tossed 200 times So it becomes 33/200 = 0.165 or 10.65% probability that ball will land in yellow section.
