Answer:
The correct answer is 
.
Step-by-step explanation:
A container contains tiles numbered from 1 through 40.
Let the experiment be to drawn a tile randomly from the container. The draws are carried on by replacement method. Then a second tile is drawn randomly.
Probability that the first tile is number 7 = 
= 
Probability that the second tile is number 25= =
Thus the probability of the first tile is number 7 and the second tile is number 25 is given by .
Answer:
<h2>
$30.24!</h2>
Step-by-step explanation:
Find the discounted price by setting up an equation
40-.3(40) AKA 30% of the original price is being taken off of the original price
Evaluate
40-12
$28 = discounted price
Sales tax is based on the reduced/discounted price* remember this
OF= multiplication (in this scenario)
.08x28
$2.24= sales tax
Add tax with discounted price
28+2.24=
<h2>
$30.24!</h2>
Answer:
35 mph
Step-by-step explanation:
As you might have learned in your physics class, the average speed of a car in mph is 50. You should write this down on some paper.
After writing it down, we need to look at what the problem is asking us, so we don't get confused. " How fast was he going on the way to the bookstore?"
This means that we need to calculate his mph speed on the way to the bookstore by subtracting something.
<em>50 mph=Average</em>
<em>Alternate Route= -15</em>
After you have written THAT down in your notes, you need to ask yourself,
"What is 50-15?"
Calculating 50-15 will make the "15 mph slower" show up and calculating that with the average will get you your answer.
50-15 is 35
1) This format that the two equations are in is called Standard Form, and it's formula is Ax+By=C. Slope-Intercept Form is another form in which linear equations can be written. It's expressed as y=mx+b. See how in SIF (Slope intercept form), the "y" is isolated? All you have to do is isolate the "y" in both equations given to you.
2x+4y=12
-2x -2x
4y=-2x+12
/4 /4
y=-1/2x+3
3x-5y=10
-3x -3x
-5y=-3x+10
/-5 /-5
y=3/5x-2
2) To graph SIF, you need to know what each aspect of the equation is. The formula is y=mx+b.
<em>m</em> stands for slope. A great way to remember it is rise/run (rise over run). Basically, the numerator in "m" is how far up you go to graph each point, and the denominator is how far left or right you go (remember, left is negative, right is positive). Let me give you an example. y=3/5x. In this formula, to graph each point, on the line, you'd go up 3, and to the <em>right</em> 5, then plot a point, then up 3, right 5, plot another one... you get it. What if the equation was y=3x though? The slope would be 3/1, or up 3, right one.
You know how to plot the points, but what coordinate do you <em>start</em><em> </em>at? That's where the Y-Intercept comes into play. The Y-Intercept is basically where the line crosses the Y-axis. The b in the SIF formula is the y-intercept, and where you plot your very first coordinate on the line. If the SIF equation was y=1x+3, your first coordinate would be on the y axis, at an elevation of 3. Since the y-axis is at x=0, the coordinate would be (0,3).
3) Look at the graph now. Where do the lines cross? The x should be somewhere between 4 and 5, and the y is somewhere between 1.5 and 2. Therefor, your "estimation" should be something like (4.5,1.75)
I really hoped this helped you! It took a while to write so I'd appreciate if you'd choose the Brainliest answer -- thanks!
