Answer:
0.9905,0.9837,0.8066
Step-by-step explanation:
Given that 10% of all steel shafts produced by a certain process are nonconforming but can be reworked (rather than having to be scrapped).
Each shaft is independent of the other and probability for non conforming is the same for each trial.
Hence X the among these that are nonconforming and can be reworked. is Bin with n =200 and p = 0.10
a)
b)
c)
Breanna used pounds of clay for her project.
Step-by-step explanation:
Step 1; First, we must convert the mixed fractions into improper fractions. To do that we multiply the whole number with the denominator and add with it the numerator while the denominator remains the same. To convert this fraction 1 , we multiply 1 with 8 and then add 4 and keep the 8 as the denominator so we get
1 = (1 × 8) + 5 / 8 =
.
Step 2; After conversion, it's just a matter of subtraction. To calculate the clay she used for her project, we subtract the clay she had after from the clay she had before doing the project. While subtracting two fractions, if denominators are equal we subtract the numerators and keep the denominator the same.
-

.
So Breanna used pounds of clay for her project.
