Answer:
answer 13.33333 hours h
Step-by-step explanation:
Julia studied 3 1/3 hours during 4 days
this means she studied:
3 1/3 of 4 days of 24 hours
3 1/3 = 9/3 x 1/3 = 10/3
and 4 days of 24 hours is 4 x 24 = 96
there for
10/3 x 96 = (10/1)x32 =320 hours
320/24 hours each day -13.3333
She didnt have enough
she would have 48 dollars in her jar
she she had 2 dollars to little
Answer: 0.00000565
Step-by-step explanation:
Required to win:
6 number match $10,000
5 number match $ 5,000
4 number match $ 1000
3 number match $ 5,00
2 number match $ 50
1 number match $ 10
Therefore, to win $10,000 ;
All 6 numbers must match
Number of right numbers = 6
Total numbers = 25
Since it is without replacement :
Probability = required outcomes / Total possible outcomes
P(First number match) = 6/25
P(second number match) = 5/24
P(third number match) = 4/23
P(fourth number match) = 3/22
P(fifth number match) = 2/21
P(sixth number match) = 1 / 20
Therefore, Probability of winning $10000 :
(6/25) * (5/24) * (4/23) * (3/22) * (2/21) * (1/20) = 720 / 127512000 = 0.0000056465
= 0.00000565
