3 3/5 gallons of gasoline would cost $4.50
This is because when you multiply 1.25 by 3 you get a product of 3.75.
Then, you multiple 1.25 with 3/5 and get a product of 0.75.
Add the two together, and you receive a sum of 4.50.
So, the cost for 3 3/5 gallon is $4.50.
Answer:
The right answer is "5.9". A further solving is provided below.
Step-by-step explanation:
The given values are:
Initial Magnitude,
M₁ = 3.9
Let Second magnitude be M₂.
Now,
⇒ 
On substituting the values, we get
⇒ 
On putting the value of "log 120", we get
⇒ 
On adding "3.9" both sides, we get
⇒ 
⇒

Answer:
The required confidence inteval = 94.9%.
Step-by-step explanation:
Confidence interval: Mean ± Margin of error
Given: A confidence interval for the true mean diameter of all oak trees in the neighbourhood is calculated to be (36.191, 42.969).
i.e. Mean + Margin of error = 42.969 (i)
Mean - Margin of error = 36.191 (ii)
Adding (i) and (ii), we get

Margin of error = 42.969-39.58 [from (i)]
= 3.389
Margin of error = 
here n= 25 
i.e.

Using excel function 1-TDIST.2T(2.054,24)
The required confidence inteval = 94.9%.
