Answer:
infinite solutions
Step-by-step explanation:
y=5/2x+2
2y= 5x +4
Multiply the first equation by 2
y = 5/2 x +2
2y = 5/2 *2 x +2 *2
2y = 5x +4
Since this is identical to the second equation (they are the same), the system of equations has infinite solutions
Answer:
0.3209
in case you dont know A z-score tells you if the distribution it comes from is normal.
Step-by-step explanation:
Check the picture below.
so notice, the sides AB and AC you can pretty much count them off the grid.
now, to get the CB side.

sum all three sides up, and that's the perimeter of the triangle.
So just find the measues of the faces
15 times 4=rightmost face
9 times 4=oposite face
9 times 4=lower top face
to find topmost face
15-9=6
4 times 6=topmost face
sides
can be split up into 2 rectangles
15 by 9 and 6 by 6
2 of them
2 times (15 times 9+6 times 6)
bottom=15 times 4
not seen face=6 times 4
total area=(15 times 4)+(9 times 4)+(9 times 4)+(4 times 6)+(2 times ((15 times 9)+(6 times 6)))+(15 times 4)+(6 times 4)
total area=60+36+36+24+(2 times (135+36))+60+24
total area=60+36+36+24+(2 times 171)+60+24
total area=60+36+60+342+60+24
toal area=582
answer is B
