Step-by-step explanation:
0.75 yard = 1 costume
1 yard = 1/0.75 =4/3 costume
6 yards = 4/3 × 6 = 8 costumes
if you wanna check,
8 costumes = 6 yards
1 costume = 6/ 8
= 3/4 (0.75) yard
The answer to your question is letter F.
Answer:
b. Because the probability of being 15 or more correct is 0.0207, it is likely that she is just guessing at the questions.
Step-by-step explanation:
-This is a binomial probability distribution with p=0.5, n=20 and x=15.
The function is expressed as:
We calculate the probability of guessing 15 or more correctly:
The probability of passing, guessing 15+ correctly, is 0.0207. This probability is very low and it is it is likely that she is just guessing at the questions
