Answer:
b) Chemistry
Step-by-step explanation:
To compare both scored we need to standardize the scores using the following equation:
Where x is the score, m is the mean and s is the standard deviation. So, 82 on chemistry is equivalent to:
Because the mean of the scores on the chemistry final exam is equal to 75 and the standard deviation is 15
At the same way, 80 on Calculus is equivalent to:
Because the mean of the scores on the calculus final exam is equal to 83 and the standard deviation is 13
Now, we can compare the values. So, taking into account that -0.2308 is lower than 0.4667, we can said that the student do better in Chemistry.

Hey Gary!
The volume of a cylinder is PiR^2h, or 3.14(r^2)h.
Let's define our measures.
Pi is 3.14 (simplified). However, our answer is requested in terms of Pi.
Our radius is 5.
Our height is 14.
Let's plug in our numbers.
5^2 • 14 • Pi
5^2 = 25
25 • 14 = 350.
350Pi is our answer.
However, rememver that we need to end our answer in units cubed, as we are using a 3-dimensional figure. Our answer is 350Pi in^3.
Your answer is B.)
I hope this helps!

The equation that can be used to find the number of emergency kits that Lexi packs is 4x=120.
Given that Lexi packs 4 water bottles into each kit and total 120 water bottles are packed by Lexi.
We are required to find the equation which can be used to find the number of emergency kits that Lexi packs.
Equation is like a relationship between two or more variables that are expressed in equal to form.Equation of two variables look like ax+by=c. It may be linear equation,quadratic equation, cubic equation and many more depending on the power of the variable that is present in that equation.
let the number of emergency kits that Lessi packs be x.
The equation which will shows the total number of bottles be:
=(Number of bottles in 1 kit)*x
Equation will be:
4x=120
Hence the equation that can be used to find the number of emergency kits that Lexi packs is 4x=120.
