Answer: 4 hours 31 min
Step-by-step explanation: first you need to simplify or solve 4/2 which is 2 because 4 divided by 2 is 2 and on Tuesday he spent 2 hours and 31 min no simply add 2 hours plus 2 hours and 31 min which gives you 4 hours and 31 min
The answer is 197.92 cubic cm
Since it's not mentioned I assume the Event of tossing a die twice are done simultaneously.
1- What is the theoretical probability that a coin toss results in two heads showing? I guess you mean: The theoretical probability of tossing 2 heads in 2 flips, if so P(1st Head) = 1/2 AND P(2nd Head) = 1/2, then the probability of getting 2 heads simultaneously is P(1st Head AND 2nd Head) = 1/2 x 1/2 = 1/4
2- What is the experimental probability that a coin toss results in two heads showing? In this case, I suggest that you toss a coin several times until 2 heads appear and then you calculate P: Assuming you get 2 heads (out of 10toss), the P(H) =2/10
3- What is the experimental probability that a coin toss results in two tails showing? Same logic as the previous one
4- What is the theoretical probability that a coin toss results in one head and one tail showing? If you get one Head, P(H) =1/2 and if you want a tail in the 2nd toss P(1/2). So P(one Head AND one tail) = 1/2 x 1/2 = 1/4
5- What is the experimental probability that a coin toss results in one head and one tail showing? Same as 3- or 4-
Answer:
<u>25</u>
Step-by-step explanation:
Let the whole number be <u>W</u>
<u>Percentage to Decimal conversion</u>
- Divide % by 100 to get the decimal
- 140/100 = 1.4
<u>Solving</u>
- 1.4W = 35
- W = 35/1.4
- W = 175/7
- W = <u>25</u>
2 3 / 8 = ( 2*8 + 3 ) / 8 = 19 / 8 ;
19 / 8 of 16 is ( 19 / 8 ) * 16 = 304 / 8 = 38 ;
