Answer: The tripled tofu is 4 lb. 14 oz. Explanation: So you first want to turn your mass into the same unit, so change the pounds of tofu into ounces. There are 16 ounces in a pound, which means the total mass of the original tofu could be written as (16 oz.) + 10 oz. = 26 oz. tofu. Multiply this by 3, and you have tripled the tofu. 3 * 26 = 78. To simplify it, divide 78 oz by 16 to find pounds, and leave the remainder in ounces. 78/16 = 4 lb. 14 oz tofu.
Answer:
Step-by-step explanation:

24 is divisible by 3.
So, (125² +25²)*(5²- 1) is also divisible by 3
A is equal to 1100 miles
B is equal to 3300 miles
You take 1650 and divide by 3 which is 550, that is 1 hour is equal to 550 miles.
Answer:
99.8% probability of at least one failure.
Step-by-step explanation:
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
Probability of success is 30%.
This means that 
Five trials:
This means that 
Find the probability of at least one failure in five trials of a binomial experiment in which the probability of success is 30%.
Less than five sucesses, which is:

In which



0.998*100% = 99.8%
99.8% probability of at least one failure.
For this case we have the following operation:
538 - 247
To subtract both numbers we must follow the following steps:
1) Subtraction is done from left to right:
2) We subtract the first digits:
8 - 7 = 1
3) We subtract the second digits:
3 - 4
Since 4 is greater than 3 then we add a digit to 3 and accumulate it for the next subtraction:
13 - 4 = 9
4) We subtract the digit accumulated in the previous subtraction to the following number:
5 - 2 - 1 = 2
Finally the result is:
538 - 247 = 291
