Answer:
1. Sample space: red or blue
2. Red: 3/5, Blue 2/5
3. 60% probability of selecting a red, 40 percent probability
4. 1 more blue
Step-by-step explanation:
3. 3/5 x 2 = 6/10 --> 60%
4. 5 total, 3 red, 2 blue (+ 1 blue) = 6 total, 3 red, 3 blue
Yes your answers look correct nice job
Answer:
Coordinate of E:(-2,3) Coordinate of G: (2.5,1.5)
Parallel: slopes both = -1/3
1/2 segment: EG length= 3 BC length=6: This is the only one I'm not sure about.
I will show the work for both the problems down below.
Step-by-step explanation:
Finding coordinates:
1+(-5)/2=-2 5+1/2=3
(-2,3)
1+4/2= 2.5 5+(-2)/2= 1.5
(2.5,1.5)
Show work verifying the EG and BC are parallel:
You can do this by finding the slope
Slop formula (y2-y1)/(x2-x1)
(1.5-3)/(2.5-(-2))
Then simplify
-1.5/2/5= -1/3 which i your slope. You use the same formula and follow thee same steps for the points of BC and both will come up as -1/4 meaning they are parallel.
Show work verifying that EG and BC are parallel:
Use distance formula to find how long each line is
√(x2-x1)^2+(y2-y1)^2
√(2.5-(-2)^2)+(1.5-3)^2
Simplify
√4.5+(1.5)=3
Do the same thing with BC and you will get 6
Answer:
[(x+5)²+(y+3)²]
Step-by-step explanation:
- length = 5 units and width = 3 units
- x is for length as y is for width
- (x+5) for length & (y+3) for width
- [(x+5)²+(y+3)²]
Answer:
x=7
y = 4
Step-by-step explanation:
Since it is a parallelogram
2x-2 =12
and 2y =8
2x-2=12
Add 2 to each side
2x-2+2 =12+2
2x = 14
Divide by 2
2x/2 =14/2
x = 7
2y =8
Divide by 2
2y/2 =8/2
y =4
