Hello,

The key to doing these problems is writing the fraction for each event and multiplying them. 

I will do the first problem for you. 

First, you have to draw an ace. The chances of that are 4/52.
Then, you have to draw a jack. The chances of that are 4/51.
We changed 52 to 51, because we didn't replace the ace that we drew the first time.

Multiplying those fractions gives us the answer 4/663.

I hope this gets you started in the right directions,
MrEQ

Find the value of 8.3 × 24.2 × 0.03. Round your answer to the nearest hundredth.
harina [27]
<span>So we need to find the value of 8.3*24.2*0.03 and round it to the nearest hundredth. So lets multiply the numbers first: 8.03 * 24.2 * 0.03 = 6.0258 and now we need to round it to the nearest hundreth. The nearest hundreth is .03 and we get: 6.03 so the correct answer is D.</span>

Question 15 of 16
Westkost [7]

The same input is being mapped into two outputs, so this is not a function.

<h3>Does the table represent a function?</h3>

A function is a relation that maps elements from the domain into elements from the range. Such that each element of the domain can be mapped into only one element of the range.

Here we have the table:

x    y

4   2

3   3

4   5

5   6

7   7

As you can see, the input x = 4 appears two times, first it is mapped into y = 2, and then it is mapped into y = 5.

Then this table does not represent a function.

What is the correct order of steps for bisecting angle ABC? Draw a ray from point B through point F. Keeping the compass the sam
Vitek1552 [10]

Answer:

Look to the explanation

Step-by-step explanation:

* Lets arrange the steps for bisecting angle ABC

- The vertex of angle ABC is B, and its rays are BA and BC

# Step 1:

- Place the compass on point B, and swing an arc that intersects rays

 BA and BC ⇒ 5th

# Step 2:

- Place point D on the intersection of the arc on ray BA and point E on

 the intersection of the arc with ray BC ⇒ 3rd

# Step 3:

- Place the compass on point D, and draw an arc inside the angle ⇒ 6th

# Step 4:

- Keeping the compass the same distance, place the compass on

 point E, and draw an arc inside the angle ⇒ 2nd

# Step 5:

- Place point F on the intersection of the arcs created from points D

 and E ⇒ 4th

# Step 6:

- Draw a ray from point B through point F ⇒ 1st

* This ray is the bisector of the angle ABC

Find three solutions of the equation y = 7x – 5.
soldi70 [24.7K]
 y=7x-5 This is the same as saying y-7x = -5 Well easy. You just make up numbers that make this work. Let x be 1 y-7=-5 y=-5+7 y=2 So one ordered pair is (1,2) Let x=2 y-14=-5 y=9 So another ordered pair is (2,9) Let x=3 y-21=-5 y=-5+21 y=16 So another ordered pair is (3,16) 
hope it helps
