Answer:
(2, 3 )
Step-by-step explanation:
The solution to a system of equations given graphically is at the point of intersection of the 2 lines.
point of intersection = (2, 3 ) ← is the solution
Answer:
Solving the expression \frac{y^2z^{\frac{1}{4}} }{(z^{\frac{1}{2}}.xy^{\frac{3}{2}})^3} we get 
Step-by-step explanation:
We need to solve the expression:
We know the exponent rule: 
Now, another exponent rule says that: 
We also know that: 
=
So, solving the expression \frac{y^2z^{\frac{1}{4}} }{(z^{\frac{1}{2}}.xy^{\frac{3}{2}})^3} we get
Answer:
2535
Step-by-step explanation:
Considering the given data-set, we have that:
- The lowest batting average is of 0.254.
- On the histogram, 5 values would fall into the class 0.251 - 0.280.
<h3>What is an histogram?</h3>
An histogram is a graph that shows the number of times each element of x was observed, or the number of elements x in a range of values, as is used for this problem.
For the given 20 batting averages given in the table, we have that:
- Looking at all of them, the lowest value of the table is of 0.254, hence the lowest batting average is of 0.254.
- The measures in the table between 0.251 and 0.28 are: 0.277, 0.265, 0.267, 0.259, 0.254. Hence, this means that on the histogram, 5 values would fall into the class 0.251 - 0.280.

Answer:
a. an = -1 • 4^(n - 1)
Step-by-step explanation:
It's easy see that each term is multiplied by 4 to get the next term, so the common ratio will be 4, that reduces the choices to answers A and B (since C and D use -1 as common ratio). Also, normally a geometric progression uses "n-1", so we'll first try with A to see if it works.
a1 = (-1) * 4^0 = -1 * 1 = -1
a2 = (-1) * 4^1 = -1 * 4 = -4
a3 = (-1) * 4^2 = -1 * 16 = -16
Yes, it works... so the answer is an = -1 • 4^(n - 1)
