Answer:
y = -2x + 19
Step-by-step explanation:
Firstly, you need to do y = mx + b
Your y is going to be from the given y coordinate (3) , the m will be the slope (-2), and the x will be the from the given x coordinate (-8).
3 = -2(-8) + b Write out equation
3 = -16 + b Simplify
+16 = +16 + b Add 16 to both sides
__________
19 = b Now you have b
y = -2x + 19
-2x is your slope and +19 is your b
solution:
You have only two qualitatively different outcomes possible. Count
the number of ways to get each of the two.
There are just two possible outcomes here: the two missing socks
make a pair (the best case) and the two missing stocks do not make a
pair (the worst case). The total number of different outcomes (the ways
to choose the missing socks) is 10 C 2 = 45.
The number of best-case ones is 5; hence its probability is 5 /45 = 1/9
The number of worst-case ones is 45 − 5 = 40; hence its probability is 40/45 = 8/9.
On average, you should expect 4 • 1/ 9 + 3 • 8 /9 = 28/ 9 = 3 1/ 9 matching pairs.
The graph of the journey is shown in the speed-time graph below
At the time = 3 minutes, Peter would have achieved the speed V.
The distance he travelled is the area under the line as shown in the graph
We first need to find the V by using the area of a rectangle formula




so V=220
the gradient the f slope then given as
