The probability of getting 4 heads when 8 heads when 8 fair coins are tossed is...
4/8=1/2 because u have to simplify.
Answer:
Step-by-step explanation:
(2+10)/2 = 12/2= 6
(2+8)/2 = 10/2= 5
(6,5)
Answer: =x4+3x3+2x2−4
Step-by-step explanation:
(x2+3x+2)(x2)−4
Distribute:
=(x2)(x2)+(3x)(x2)+(2)(x2)+−4
=x4+3x3+2x2+−4
Answer:
(262, 690)
Step-by-step explanation:
Given that :
Mean score = 476
Standard deviation, s = 107
2 standard deviations above and below the mean :
Mean ± 2s
Hence,
2 standard deviations below :
476 - 2(107)
476 - 214 = 262
2 standard deviations above
476 + 2(107)
476 + 214 = 690
The water could reach 14 - 2 = 12 inches
