Answer:
a. 19.68 miles per gallon.
b. 26.32 miles per gallon.
Step-by-step explanation:
Mean gas mileage (μ) = 23.0 mpg
Standard deviation (σ) = 4.9 mpg
In a normal distribution, for any length X, the z-score is determined by the following expression:

In a normal distribution, the 25th percentile (first quartile) of a normal distribution has a corresponding z-score of z = -0.677 and the 75th percentile has a corresponding z-score of z = 0.677
a. The first quartile of the distribution of gas mileage is

19.68 miles per gallon.
b. The third quartile of the distribution of gas mileage is

26.32 miles per gallon.
The answer is A
8.5% sales tax + 38.00= $41.23 x 5 (shirts)= $206.15
4a+9=(-9+30-25). 4a+9=30-34. 4a+9=-4. 4a=-13. A=-3.25 :)
Hello there!
The larger integer is 114.
x + (x + 2) = 226
Combine like terms
2x + 2 = 226
Subtract 2 from both sides
2x = 224 Divide
x = 112
The two integers are 112 and 114. But they asked us for the lager integer. So 114 is the answer.
I hope this helps! As always, it is my pleasure to help students like you!
