Answer:
$53.70
Step-by-step explanation:
I worked it out I think this is the answer
Here we shall use the binomial distribution formula to evaluate the probability:
let the probability that the temp will be above 80 be P(F)=2/3;
Probability that the temp will be below 80 be P(F')=1/3
thus,
The probability that the temp will be above 80 for 20 days for the month of June will be:
P(F)=n!/((n-x)!x!)p^xq^(n-x)
p=2/3 and q=1/3, n=30, x=20
plugging the values in the equation we obtain:
P(F)=30!/(10!*20!)*(2/3)^20*(1/3)^(30-20)
P(F)=0.153
It is reasonable. Since 255,113 is closer to 300,000 than 200,000 on the number line, you can round the number to 300,000.
So its going to equal a fraction.
To convert let x equal the repeating decimal (0.1515... it would usually have a line on top of it but I cant type it)
Then examine the number see what place it is in then add another place (in this case it is in the 10000ths place) so multiply it but 10000x
so it would look like: 10000x = 0.1515
then you will move the decimal in to a whole numbers place (0.1515 to 1515.1515
then subtract the decimal 1515.1515- .1515= 1515.
dont forget to subtract from both sides so subtract the 10000x too. (999.515)
then write as fraction form 1515/9999
Answer:
None of the answers are correct, because 12/15=4/5, it's equivalent to 12 divided by 15.
