Bill and Ben each have three cards, numbered 1, 2 and 3. They each take one of their own cards. Then they multiply together the two numbers on the cards. a) What is the probability that their answer is an even number? b) What is the probability that their answer is a number greater than 5?
Answers
The probabilities are given as follows:
a) Even number: 5/9.
b) Number greater than five: 1/3.
What are probabilities?A probability is the division of the number of desired outcomes by the number of total outcomes.
Given that each person draws one card from a set of three, hence the total number of outcomes is given as follows:
3² = 9.
Using the Fundamental Counting Principle,
The nine outcomes are given as follows:
1 x 1 = 1.
1 x 2 = 2.
1 x 3 = 3.
2 x 1 = 2.
2 x 2 = 4.
2 x 3 = 6.
3 x 1 = 3.
3 x 2 = 6.
3 x 3 = 9.
There are five outcomes that end with an even number, hence the probability is of:
p = 5/9.
There are three outcomes ending with a number greater than five, hence the probability is of:
p = 3/9 = 1/3.

10(c–1)=80 i need help
Answers
Answer:
C =9
Step-by-step explanation:
10(c−1)=80
Step 1: Simplify both sides of the equation.
10(c−1)=80
(10)(c)+(10)(−1)=80(Distribute)
10c+−10=80
10c−10=80
Step 2: Add 10 to both sides.
10c−10+10=80+10
10c=90
Step 3: Divide both sides by 10.

A swift is a bird that can fly 3 times faster than a wolf can run. A swift can fly 120 miles per hour. Which equation would be used to find how fast w, a wolf can run
120 x w = 3w
W x 3 =120
3 + w = 120
120 + 3 = 3
Answers
Answer:
It would be "W x 3 = 120"
Step-by-step explanation:
Why? Well, since a swift could run 120 miles an hour, that would be a necessity in the problem. It would be needed to find out how fast the wolf ran, but, it cannot be the answer since we are trying to find out "how fast the wolf ran per hour". Right? No. Basically, you need to divide 120 by 3, which is 40. But which equals 40? None. Yes, none. No, to two answers. Why? Because you need to divide, so, the answer could be multiplication, but the opposite. You know if you know... Anyways, 120 x w = 3w is wrong due to the fact that it has no sign of division and the answer is way too large (I tried). 3 + w = 120 is definitely wrong. Why add? 3 + 40 is not 120. It's 43. Also, 120 + 3 is not 3, it's "123". So, the only answer left is "W x 3 = 120". But, how do we know that it's right? Well, think about it backwards. The swift is 3 times faster, so, the wolf times that 3 times faster is 120. And that is exactly what this problem is. By doing the problem backwards, we could find out that a wolf can run 40 miles per hour. Basically, 120 divided by 3, how much faster it is than a wolf, is 40. So, we could find out that a wolf could run 40 miles per hour.
Final Answer: W x 3 = 120
Answer:
The answer will be w×3=120
Write an equation of a line that passes through the point (8, 4) and is parallel to the line y = 4x + 2.
Oy = 4x - 28
Oy = 4x + 28
Oy=-x-2
4
Oy=x+ 2
4
revious Question
Answers
y = 4x - 28
Step-by-step explanation:
When two lines are parallel, their slope stays the same. thus we have y = 4x (so far)
Then use the point (8, 4) to plug in the coordinates to y = 4x + b
y = 4x + b (because y-intercept changes)
4 = 4(8) + b
4 = 32 + b
b = 4 - 32
b = -28
the y-intercept is -28 and the equation of the line that passes through the point (8, 4) and is parallel to the line y = 4x + 2 is y = 4x - 28
It took Jack 2 hours to paddle 6.4 km upstream on the Black River to the giant's castle. The speed of the river is 1.8 km/h. How long will it take Jack to cross Swan Lake if the lake is 2.5 km long?
Answers
To find the time Jack takes to cross Swan Lake, his average speed is required:
The time it will take Jack to cross Swam Lake is 0.5 hours
Reason:
Time it took Jack to paddle 6.4 km upstream, t = 2 hours
Distance Jack paddled, d = 6.4 km
The given speed of the Black River, v₂ = 1.8 km/h
The width of the lake, w = 2.5 km
The time it will take Jack to cross Swan Lake
Let v₁, represents Jack's speed, we have;
[tex]v_1 - v_2 = \dfrac{d}{t}[/tex]
Therefore;
[tex]v_1 - 1.8 = \dfrac{6.4}{2} = 3.2[/tex]
v₁ = 3.2 + 1.8 = 5
Jack's speed, v₁ = 5 km/h[tex]Time \ to \ cross \ the \ lake , \ t_S = \dfrac{w}{v_1}[/tex]
[tex]t_S = \dfrac{2.5 \, km}{5 \, km/h} = 0.5 \, hr.[/tex]
The time it will take Jack to cross Swan Lake, [tex]t_S[/tex] = 0.5 hours

A. Post your response to the discussion board.
Using the following 3 equations, answer the questions:
11 x plus y equals 4 space x plus y equals negative 2 space x minus 2 y equals 18
How can you determine which equations can be graphed more easily using x- and y-intercepts, rewriting in slope-intercept form, or using a table of values?
Which method works best for you personally? When does it not work as well?
Answers
Answer:
Step-by-step explanation:
I tried to translate "11 x plus y equals 4 space x plus y equals negative 2 space x minus 2 y equals 18"
This is what I got:
11x + y = 4
x+y=-2
x-2y=18
For me, personally, I need to rewrite these equations into standard format of y=mx+b (slope intercept):
-------
11x + y = 4
y=-11x+4
-------
x+y=-2
y=-x-2
-------
x-2y=18
2y = x-18
y=(1/2)x-9
------
For each one I can find the y-intercept easily: (4, -2. and -9). I can quickly generate a second point by assuming a convenient value for x (one that makes the calculation simple).
1. y=-11x+4 let x = 1; y = -7 : (1,-7)
y=-x-2 let x = 2; y= -4 : (2,-4)
y=(1/2)x-9 let x= 2; y=-8 : (2,8)
The y-intercepts tell us at point on the line for each equation:
(4, -2. and -9) means points at (0,4), (0,-2) and (0.-9)
Now we have two point for each line equations. All we have to do is mark those two points for each equation and draw a line through them. Easy!
The two points for each equation are:
1. (1,-7), (0,4)
2. (2,-4), (0,-2)
3. (2,8), (0.-9)
This always works well for equation of lines. More comples equations involving parabolas, etc., are more easily graphed using tables of the results of various x inputs.
