Answer:
X= -7/6, 17/8
Step-by-step explanation:
Foil it, then use quadratic to find zeros/roots.
Okay lets create an eqn from that information
A first int, B second int, C third int, D fourth int.
B = A + 2
C = A + 4
D = A + 6
A is the smallest integer
B + D = 0.5 (A + C)
Now lets substitute
(A + 2) + (A + 6) = 0.5(A + (A + 4))
now lets dist
2a + 8 = 0.5(2a +4)
2a + 8 = a + 2
a + 8 = 2
a = -6
B = -6 +2
B = -4
C = -6 + 4
C = -2
D = -6 + 6
D = 0
Now using B + D = 0.5(A + C)
-4 + 0 = 0.5(-6 + (-2))
-4 = 0.5 (-8)
-4 = -4
Correct
Therefore, First integer is -6, second integer is -4, third integer is -2 and fourth integer is 0
D. The set of all points in a plane that are equidistant from a fixed point.
is there anther way you can put the pic i cant see
Answer:
- 16. 3/8
- 17. 1/8
- 18. 5/18
- 19. 0
- 20. 1
Step-by-step explanation:
<u>As per the spinner we have:</u>
- Green = 1/2 - 1/16 = 7/16
- Red = 1/4
- Purple = 1/8
- Orange, blue, yellow = 1/16
<u>16. P(red, yellow, blue) = ?</u>
- P = 1/4 + 1/16 + 1/16 = 3/8
<u>17. P(orange, yellow) = ?</u>
<u>18. P(green, blue, purple) = ?</u>
- P = 7/16 + 1/16 + 1/8 = 10/16 = 5/8
<u>19. P(pink) = ?</u>
<u>20. P(red, orange, yellow, green, blue, purple) = ?</u>
- P = 1 as all possible colors selected
