The polynomial that represents the perimeter of the rectangle is P = 6x + 16y
<h3>What are perimeters?</h3>
The perimeter of a shape is the sum of the side lengths of the shape
For all regular quadrilaterals, you add up the side lengths to determine the perimeter
<h3>How to determine the polynomial that represents the perimeter of the rectangle?</h3>
The given parameters are
Length = 5x + 2y
Width = 6y - 2x
The polynomial that represents the perimeter of the rectangle is represented as
P = 2 * (Length + Width)
Recall that:
Polynomial expressions are mathematical statements that are represented by variables, coefficients and operators
So, we have
P = 2 * (5x + 2y + 6y - 2x)
Evaluate the like terms
So, we have
P = 2 * (3x + 8y )
Open the brackets
P = 6x + 16y
Hence, the required polynomial is P = 6x + 16y

Answer:
b. A smaller sample size would increase the effectiveness of a hypothesis test.
Step-by-step explanation:
A hypothesis test is an important procedure in the field of statistics. It evaluates any two mutually exclusive statements about a population that determines and tells which statement made best supports to the sample data provided.
Now we know that an increase in the sample size makes the hypothesis test more effective and sensitive and it is more likely to reject the null hypothesis.
The probability of making a type I error is known as the Alpha while the probability of making type II error is called Beta.
Thus the correct option is (b).
Answer:
56 baseball's? I'm kinda confused twice as many baseball's or what? in any case 28 twice is 56.
