Number two:two thirds equals eight twelfths
Number six:ten fifthteenths or two thirds
53.96+0.17x =57.96+0.12x
0.17x-0.12x=57.96-53.96
0.05x=4.00
x=80 mi
10 -3.5 and 10 -8.5 is the answer I think
Answer:
See below.
Step-by-step explanation:
First, notice that this is a composition of functions. For instance, let's let and . Then, the given equation is essentially . Thus, we can use the chain rule.
Recall the chain rule: . So, let's find the derivative of each function:
We can use the Power Rule here:
Now:
Again, use the Power Rule and Sum Rule
Now, we can put them together:
Answer:
the margin of error is 0.05
Step-by-step explanation:
Margin of error = confidence interval ÷ 2
MOE = CI ÷ 2
Confidence interval CI = 0.2 - 0.1 = 0.1
MOE = CI ÷ 2 = 0.1 ÷ 2 = 0.05
the margin of error is 0.05
