Answer: 0.80

Step-by-step explanation:

Given : The owner of the West End Kwick Fill Gas Station wishes to determine the proportion of customers who pay at the pump using a credit card or debit card.

He surveys 100 customers and finds that 80 paid at the pump.

Then, sample proportion= \dfrac{80}{100}=0.80

Since , the best point estimate for population proportion is sample proportion.

Therefore, the estimated value for population proportion =0.80

Square and Rhombus are the following quadrilaterals have diagonals that are always  perpendicular to each other.

C. Square

D. Rhombus

<u>Step-by-step explanation:</u>

This implies the diagonals of a square and rhombus are perpendicular. The diagonals of a square and rhombus are a similar length. In elementary geometry, the property of being opposite is the connection between two lines which meet at a right angle. The property stretches out to other related geometric items.  

Principally Perpendicular lines will be lines that cross at a right (90 degrees) edge. so when it goes under shape rhombus and square have the equivalent of a considerable number of sides parallelly.

-43 - 4r = 3( 1 - 9r )
Karolina [17]

-43 - 4r = 3 - 27r

Add 27r to both sides. -43 - 4r + 27r = 3 -27r + 27r or -43 + 23r = 3

Add 43 to both sides. -43 + 43 +23r = 3 + 43 or 23r = 46.

Divide both sides by 23 to get r by itself. 23r / 23 = 46 / 23 or r = 2

r = 2
