Answer: (9,7)
Step-by-step explanation: 32 Divided by 4 = 9 and 28 Divided by 4 = 7.
So there would be 9 Blue and 7 Red
Answer:
Probability to get tails exactly 8 times or exactly 5 times is 0.29
Step-by-step explanation:
No of ways the coins lands tails exactly 8 times
P(8) = 15C8 × 
× 
No of ways the coin lands tails exactly 5 times
P(5) = 15C5 × 
× 
Probability to get tails exactly 8 times or 5 times
P(8)+P(5) = 15C8 × 
+ 15C5 ×
P = ( 15C8 + 15C5 )
P = ( ( 
) + ( 
) )
P = ( 6435 + 3003 )
P = ( 9438)
P = 
( 4719)
P = 
P = 0.29
Your answer would be 18. AC must be longer than 9
Answer:
The number of horses that can eat 4 stacks of hay in 8 days = 56 horses
Step-by-step explanation:
The given parameters are;
The time it takes 16 horses to eat 5 stacks = 35 days
Therefore;
The time it takes 16 horses to eat 5/5 stacks (1 stack) = 35 days/5 = 7 days
The time it takes 16 horses to eat 1 stack of hay = 7 days
The time it takes 16 horses/16 to eat 1 stack of hay = 7 days × 16 = 112 days
Therefore;
The time it takes 1 horse to eat 1 stack of hay = 112 days
The time it takes 1 horse to eat 4 × 1 stack of hay = 112 days × 4 = 448 days
The time it takes 1 horse to eat 4 stacks of hay = 448 days
Therefore, given that (448 days)/(8 days/horse) = 56 horse, we have;
The number of horses that will eat 4 stacks of hay in 8 days = 56 horses.
300
because 5x5 = 25 and after that u work from left to right so 25x2 is 50 and 50x6 is 300
