Answer:
Option D is correct.
$408.04 the gas would cost for this car to travel 2,727 typical miles
Step-by-step explanation:
Unit rate defined as the rates are expressed as a quantity 1 such as 3 miles per second or 4 kilometer per hour
As per the statement:
A car averages 27 miles per gallon.
⇒
Total distance of car travel typical miles = 2727 miles.
Substitute the given values we have;
It is also given that if gas costs $4.04 per gallon.
then;
In 1 gallon of gas = $4.04
then;
in 101 gallons of gas =
Therefore, $408.04 the gas would cost for this car to travel 2,727 typical miles
Answer:
84.13% of bottles will have volume greater than 994 mL
Step-by-step explanation:
Mean volume = u = 1000
Standard deviation = = 6
We need to find the proportion of bottles with volume greater than 994. So our test value is 994. i.e.
x = 994
Since the data is normally distributed we will use the concept of z-score to find the required proportion. First we convert 994 to its equivalent z-score, then using the z-table we will find the corresponding value of proportion. The formula to calculate the z score is:
Substituting the values, we get:
This means 994 is equivalent to a z score of -1. Now we will find the proportion of z values which are greater than -1 from the z table.
i.e. P(z > -1)
From the z-table this value comes out to be:
P(z >- 1) = 1 - P(z < -1) = 1 - 0.1587 = 0.8413
Since, 994 is equivalent to a z score of -1, we can write that proportion of values which will be greater than 994 would be:
P( X > 994 ) = P( z > -1 ) = 0.8413 = 84.13%
