Answer:
25 + 0.15m = 71.8
Step-by-step explanation:
Given:
Fixed charge = $25
Additional charge for each mile = $0.15
Let number of miles driven be m.
Total Billed amount = $71.80
Now total bill amount is calculated by adding fixed charge with additional charge for each mile times number of miles.
Hence,
Total Billed amount = Fixed charge + Additional charge for each mile × number of miles driven
25 + 0.15m = 71.8
Hence the equation is 25 + 0.15m = 71.8.
Answer:
The 97% confidence interval would be from 108 to 165.
Step-by-step explanation:
Since the 78% confidence interval is from 87 to 133, to determine what the 97% confidence interval would be, the following calculations must be performed:
78 = 87
97 = X
97 x 87/78 = X
8.439 / 78 = X
108.19 = X
78 = 133
97 = X
97 x 133/78 = X
12.901 / 78 = X
165.39 = X
Thus, the 97% confidence interval would be from 108 to 165.
Answer:
a
Step-by-step explanation:
Answer:
Compare LHS and RHS to prove the statement.
Step-by-step explanation:
Given: a + b + c = 0
We have to show that
We take LCM, simplify the terms and compare LHS and RHS. We will see that LHS = RHS and the statement will be proved.
Taking LCM, we get:
= 1
⇒
We simplify each term and then compare LHS and RHS.
Simplifying the first term:
=
=
Now, we simplify the second term we have:
=
=
Again, simplifying ,
=
= (C)
Therefore, LHS = A + B + C
=
Similarly. RHS
=
Note that if a + b + c = 0,
So, RHS =
We see that LHS = RHS.
Therefore, the statement is proved.
