Step-by-step explanation:
There are initially pencils in the bag.
Take a pencil out of this bag of 47 pencils. 15 out of the 47 pencils blue. Let represent the event of getting a blue pencil on the first pick. The probability of getting a blue pencil is:
.
There are now pencils left in the bag. However, given that the first pencil removed from the bag is blue, the number of red pencils in the bag will still be 24. Take another pencil out of this bag of 46 pencils. Let
represent the event of getting a red pencil on the second pick. The possibility that the second pencil is red given that the first pencil is blue will be:
.
The question is asking for the possibility that the first pencil is blue and the second pencil is red. That is:
.
Answer:
Graph the equation is shown below.
Step-by-step explanation:
The linear equation representing the relation between cost of ordering a pizza and the number of additional toppings is:
Here,
<em>y </em>= cost of the pizza
<em>x</em> = number of toppings
The graph of the linear equation is shown below.
Consider the point (2, 10.25).
When <em>x</em> = 2 compute the value of <em>y</em> as follows:
The point (2, 10.25) satisfies the equation.
Again consider a point (18, 18.25).
When <em>x</em> = 18 compute the value of <em>y</em> as follows:
The point (18, 18.25) satisfies the equation.
The two points are also plotted on the graph.
