Answer:
0.648
No, that is not an unusually low number of correct guesses.
Step-by-step explanation:
Suppose you take a 15 question True or False quiz and you guess on every problem. You only get 3 correct. Then
- correct;
- o\incorrect.
The probability of getting 3 or fewer correct guesses is

Using the criteria that a number 3 is unusually low if P(3 or fewer) ≤ 0.05, we can state that 3 is not an unusually low number of correct guesses.
Answer:
see below
Step-by-step explanation:
m/3 + 4 = 7
Subtract 4 from each side
m/3+4-4 = 7-4
m/3 = 3
Multiply each side by 3
m/3*3 = 3*3
m =9
18 plus 12 divided by 2 = thats how u get the answer
This is the best I got Require to make 2 equations with the same repeating part and subtract them to eliminate the repeating part.
begin by letting x = 0.5555555................. (1)
To obtain the same repeating part after the decimal point need to multiply by 10
hence 10x = 5.555555........................(2)
It is important to obtain 2 equations in x, where the recurring part after the decimal points are exactly the same.
now subtract (1) from (2) to obtain fraction
(2) - (1) : <span>9x=5⇒x=<span><span>59</span></span></span>
