Step 1: Put a decimal point at the end of the number: 2445000000.<span>
Step 2: Move the decimal point 9 spaces to the left: </span>2.445000000
Number: 2.445000000 aka 2.445<span>
Exponent: 9
Answer: 2.445 x 109</span>
Combine like terms such as 3x and 5x and combine 4 and 3
the answer would be 8x+7
mark me brainliest if the answer is correct, thank you in advance :)
21/28 can be simplified to:
3/4
Any fraction that is equal to 3/4 or 75% will be equivalent.
Examples:
30/40, 75/100
Answer:
2/7
then 2/14
Step-by-step explanation:
Let P(H)=p be the probability of one head. In many scenarios, this probability is assumed to be p=12 for an unbiased coin. In this instance, P(H)=3P(T) so that p=3(1−p)⟹4p=3 or p=34.
You are interested in the event that out of three coin tosses, at least 2 of them are Heads, or equivalently, at most one of them is tails. So you are interested in finding the likelihood of zero tails, or one tails.
The probability of zero tails would be the case where you only received heads. Since each coin toss is independent, you can multiply these three tosses together: P(H)P(H)P(H)=p3 or in your case, (34)3=2764.
Now we must consider the case where one of your coin flips is a tails. Since you have three flips, you have three independent opportunities for tails. The likelihood of two heads and one tails is 3(p2)(1−p). The reason for the 3 coefficient is the fact that there are three possible events which include two heads and one tails: HHT,HTH,THH. In your case (where the coin is 3 times more likely to have heads): 3(34)2(14)=2764.
Adding those events together you get p3+3(p2)(1−p)=5464. Note that the 3 coefficient
I'm pretty sure it's <em>C</em>
Step-by-step explanation:
2/3=8/12
8/12 ....divided both by 4=2/3
2/3=2/3
