(-3,4)(-6,-1)
The easy way
look at the y's = 4 and -1 the difference is 5 now /2 = 2.5
so the y midpoint is 2.5 from each point or 1.5
look at the x's = -3 and -6 the differebce is 3 now /2 = 1.5
so its 1.5 from each point or -4.5
so midpoint is (-4.5, 1.5) or (-9/2, 3/2) or C
the formula way:
for x
x1+x2/2
-3+-6/2
-9/2 (which is -4.5)
for y
y1+y2/2
4+-1/2
3/2 (which is 1.5)
Answer:
100 centigrams
Step-by-step explanation:
Multiply the mass value by 100
Well, let's first write these as points.
( 2 , 50 )
( 4 , 100 )
We can see that when "x" is reduced by 2, "y" is reduced by 50. This means that if we reduce "x" by 1, "y" will be reduced by 25. Thus, we can say that if "x" is 1, "y" will be 25.
( 1 , 25 )
What we know that 25 * 1 = 25, and that 2 * 25 = 50. We can see that multiplying "x" by 25 will give us our "y". We can now write this as an equation.
y = 25x
Answer:
Step-by-step explanation:
Start by finding how many integers there are from 10-30...
30-10+1=20+1=21
Note we have to add 1 since it is inclusive.
Now, let's find how many multiples of 4 or 5 there are from 10-30...
4*3=12
4*4=16
4*5=20
4*6=24
4*7=28
5*2=10
5*3=15
5*4=20
5*5=25
5*6=30
5+5-1=9
Note we have to subtract 1 since 20 is counted twice.
The probability would be...
