Answer:
your answer would be 520
Step-by-step explanation:
13 x 40 = 520
128 : 3 :: w : 8 proportion
3w = (8)(128) product means/extremes
w = 341 ⅓ cars
Y=-x^2 is non linear due to the x being squared
Answer:
x=6
Step-by-step explanation:
4x-15=2x-3
+15 +15
4x=2x=12
/2 /2 +12
2x=12
/2 /2
x=6
Total cards = 52
Total red cards = 26
Total black cards = 26
P(one red and one black) = P(red and then black)+ P(black and then red)
P(one red and one black) =(26/52)(26/51) + (26/52)(26/51)
P(one red and one black) = 26/51 (Answer A)
