It is true. Those 3 are all undefined
Total area of the wall = 28 * 12 = 336 ft²
time = 5 1/4 = 21/4 hours
speed = 336 / 21/4 = 64 ft²/hour
Ok.45%=45/100.then you just need to simplfy it.so 45÷5/100÷5 =9/20.the answer is c.hope this help.
Answer:
The probability is 10/121
Step-by-step explanation:
In this question, we are tasked with calculating probability.
The probability to be calculated is that we have an ordered selection of picking a red marble after which we pick a yellow marble.
Firstly let us know the total number of marbles we have. That will be 4 + 5 + 2 = 11 marbles
Probability of picking a red marble will be 5/11 while the probability of picking a yellow marble will be 2/11
Now, the probability of picking a red marble before a yellow marble will be mathematically equal to; P(r) * P(y) = 5/11 * 2/11 = 10/121
