The probability that a person wins the game is 32.1%

Based on the information given, the following can be depicted. It should be noted that there are 6 sides as well as 4 cards.

Therefore, the numbers on the dice i.e from 1 - 6 will be represented 4 times each. This gives a total of (4 × 6) = 24. There are also 4 cards. The total in sample space will now be:

= 24 + 4 = 28

The frequency table will be such that 28 or more have a relative frequency of 9. Therefore, the probability that a person wins the game will be:

= 9/28 = 32.1%

When you win 25% of the time, this illustrates that the number of products picked will be:

= 25% × 28

= 7 products.

The probability of participants achieving a winning score of 36 or higher in four consecutive attempts will be:

= 1/6⁴ = 1/1296

Answer:

[tex]\frac{x-3}{2x-3}[/tex]. hole or removable discontinuity at x=2

Step-by-step explanation:

Well generally if you want the simplest form, you factor each the denominator and numerator and then see if you can cancel any of the factors out (because they're in the denominator and numerator)

So let's start by factoring the first equation:

[tex]x^2-5x+6[/tex]

Now let's find what ac is (it's just c since a=1...)

[tex]AC= 6[/tex]

List factors of -6

[tex]\pm1, \pm2, \pm3, \pm6[/tex].

Now we have to look for two numbers that add up to -5. It's a bit obvious here since there isn't many factors, but it's -2 and -3, and they're both negative since 6 is positive, and -5 is negative...

So using these two factors we get

[tex](x-2)(x-3)[/tex]

Ok now let's factor the second equation:

[tex]2x^2-7x+6[/tex]

Multiply a and c

[tex]AC = 12[/tex]

List factors of 12:

[tex]\pm1, \pm2, \pm3, \pm4, \pm6, \pm12[/tex].

Factors that add up to -7 and multiply to 12:

[tex]-3\ and\ -4[/tex]

Rewrite equation:

[tex]2x^2-4x-3x+6[/tex]

Group terms:

[tex](2x^2-4x)+(-3x+6)[/tex]

Factor out GCF:

[tex]2x(x-2)-3(x-2)[/tex]

Rewrite:

[tex](2x-3)(x-2)[/tex]

Now let's write out the equation using these factors:

[tex]\frac{(x-2)(x-3)}{(2x-3)(x-2)}[/tex].

Here we can factor out the x-2 and the simplified form is:

[tex]\frac{x-3}{2x-3}[/tex]

So we can "technically" define f(2) using the most simplified form, but it's removable discontinuity, so it has a hole as x=2. since it makes (x-2) equal to 0 (2-2) = 0.

Thus, the rate of change per gallon of gas is 60 miles per gallon.

A motorcycle consumes 5 gallons of gas for 300 miles and 7 gallons for 420 miles.

Rate of change is defined as the change in value with rest to the time is called rate of change.

Now,

Rate of change = Difference B/w volume (i.e. in gallons)  /difference in miles
= 420-300/7-2
= 60 gallons/mile

Thus, The required rate of change per gallon of gas is 60 miles per gallon.

It took 1.9 years to pay back the loan.

Interest is the amount of money given or received when a certain sum of amount is received as a loan or given or deposited for investment.

It is given that

Principal amount of loan = $ 8000

Interest paid = $ 600

Rate = 4%

Time Period = ?

Assuming Simple Interest has been applied

I = ( P* R* T) /100

600 = ( 8000 * 4 * T ) / 100

60000 = 8000 * 4 * T

T = 1.875 years

T = 1.9 years rounded to 1 decimal

T = 22.5 months

4. Change in y/change in x (m) or rise/run

5. Rewrite the equation in slope-intercept form to find the value of the y-intercept. The value of x will always be 0.

The equation, y = mx + b, in slope-intercept form, defines a line, where m is the slope and the y-intercept = b.

1. Slopes of vertical lines are always undefined, therefore, for a vertical line that contains (a, b), the equation would be: x = a.

2. Horizontal lines have a slope of 0, therefore, the equation of a horizontal line that contains the point, (a, b), will  be: y = b.

3. The slope of a vertical line is undefined.

4. Two ways of finding the slope if we are given two points on a line are:

Change in y/change in x (m) = y2 - y1 / x2 - x1

or

rise/run

5. If we have an equation in point-slope form, for example, y - 2 = 2(x - 4), rewrite the equation in slope-intercept form and find the value of the y-intercept:

Answer:

8

Step-by-step explanation:

Midpoint means half point of a certain shape. This means that if all the points of OPQ are midopoints of the bigger triangle, then OPQ has to be half the size of the big triangle. There are two ways to figure this out. The first way is to add all the numbers up to find the perimeter of the big triangle (6+6+4) which is 16. Then, you can do 16/2 to get the perimeter of the smaller triangle which is 8. The other method is to take each value of the bigger triangle and divide them by 2 (6/2, 6/2, 4/2). When you do that, you get (3, 3, 2). Now, you just add those values (3+3+2) which gets you 8 gor the smaller triangle. I hope this helps!

There are 5 segments between T and M, and the difference between T and M is:

5/8 - (-1/4) = 5/8 + 2/8 = 7/8

The measure of each segment will be equal to:

m = (7/8)/5 = 7/(8*5) = 7/40

Now, coordinate R is 2 segments to the left of T, so the coordinate of point R is given by:

Step-by-step explanation:

In the question, it is given that the city's population is growing linearly. In 2008 , population was 28200 and in 2012 , it is 36800 .

It is required to predict the population in 2014 .

To do so, use the population given in two years as two points on a line and find the equation of population and year. Then, find the population in year 2014 .

Step 1 of 2

The population in 2008 was 28200 and in 2012 it was, 36800 .

The equation relating population and year is,

[tex]$$\begin{aligned}&y-28200=\left(\frac{36800-28200}{2012-2008}\right)(x-2008) \\&y-28200=\left(\frac{8600}{4}\right)(x-2008) \\&y-28200=2150(x-2008)\end{aligned}$$[/tex]

Step 2 of 2

The population in year 2014 can be determined by substituting 2014 for x,

[tex]$$\begin{aligned}&y-28200=2150(2014-2008) \\&y-28200=2150(6) \\&y-28200=12900 \\&y=41100\end{aligned}$$[/tex]
