Answer:
EF=6
Step-by-step explanation:
E is the midpoint, so DE = EF
DE = 15-3x
EF = x+ 3
Since DE = EF,
15 - 3x = x + 3
-4x = -12
x = 3
If x = 3,
DE = 15 - 3*3, 15 - 9 = 6
EF = x+ 3, so EF = 3 + 3 = 6
18 girls and 12 boys 18+12= 30
Brake it up into 15
The theoretical probability of a yellow marble would be 8/24 or 33.3%. (this is found by adding all possibilities so 10+4+2+8 and dividing it by the yellow). The experimental probability was 8/16 or 50% so a 16.67% higher probability than the expected
