Answer:
Since P(0) and P(1) have not the same values for the probability, X is not a discrete uniform random variable.
Step-by-step explanation:
Probability of data to be correct: 0.5
Probability of data being incorrect: 0.5
The random variable X is the number of fields that have an error within the range of 28.
P(0) = 
P(1) = 
Answer:
Step-by-step explanation:
1. $800 x 8 yrs. = $6,400
2. the interest = $704
3. total would be $7,104
btw to for step 2 this is what i did:
$800 x 0.11 (the interest rate in a decimal form)= $88 then $88 x 8 years= 704
Answer:
9/16
Step-by-step explanation:
First, note that 10000 multiplied by .5625 will get rid of the decimal point. Therefore, make a fraction where the numerator is .5625 times 10000 and denominator is 10000 like this:
.5625 x 10000
10000
Next, multiply the numbers in the numerator together and keep the denominator as is. Now our fraction looks like this:
5625
/10000
The greatest common factor of 5625 and 10000 is 625, which means you can divide the numerator and denominator by 625 and keep the same value:
5625 ÷ 625
/10000 ÷ 625
And when calculating the numerator and denominator in our fraction above, we get .5625 as a fraction in the simplest form possible:
.5625 =
9
/16
When you draw this out, what you have is a right triangle problem. The height of the rope from the ground is 12 (a side), the distance she is from the base of the tree is 5 (a side), and the length of the rope is the hypotenuse. Use Pythagorean's Theorem to find the length of the hypotenuse: 5^2+12^2 = c^2 or
25+144 = c^2 and c^2 = 169, which makes the length of the rope come out to be 13 feet long.
Mean a=75/10, mean b=73/10............about the same
range a=2-10=8, range b=4-12=8.........about the same
