A linear function contains the following points. (-2,8) (0,6) What are the slope and y-intercept of this function?​

The revenue equation of the item is r = 3.56q

The given parameters are:

Expense equation, E = 3.2q + 56000

Selling price = 3.56 per item

This means that the selling price equation is

S = Selling price per item * Number of items

So, we have

S = 3.56 * q

This gives

S = 3.56q

The total selling price of the item is the same as the revenue equation

So, we have

r = 3.56q

Note that the revenue equation is also a linear equation

Where linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient

Hence, the revenue equation of the item is r = 3.56q

The y-intercept of 32 represents that: It is the melting point of water on the Fahrenheit scale.

The general form of expression of Linear functions in slope intercept form is:

y = mx + c

where:

m is slope

c is y-intercept

Now, the equation is given as:

F = 2C + 32

Thus:

Slope = 2

The solution to the proportional relationship (2x - 4)/39 = (x + 6)/24 is given as follows:

x = 36.67.

The proportional relationship for this problem is defined as follows:

(2x - 4)/39 = (x + 6)/24

As the measures are proportional, we can apply cross multiplication, hence:

24(2x - 4) = 39(x + 6).

Applying the distributive property to each side of the equality, we have that:

48x - 96 = 39x + 234

Hence, isolating x, the solution is obtained as follows:

48x - 39x = 234 + 96

9x = 330

x = 330/9

x = 36.67.

The experimental probability of drawing an A or 2 is 1/10.

What is probability?

Probability is a measure of the likelihood or chance of an event occurring. It is a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event.

To find the experimental probability of drawing an A or 2, we need to add the frequency of drawing an A and the frequency of drawing a 2 and divide it by the total number of draws.

Frequency of drawing an A = 8

Frequency of drawing a 2 = 12

Total frequency of drawing an A or 2 = 8 + 12 = 20

Total number of draws = 200

Experimental probability of drawing an A or 2 = Total frequency of drawing an A or 2 / Total number of draws = 20 / 200 = 1/10

Therefore, the experimental probability of drawing an A or 2 is 1/10.

Answer: Number of games lost = 23 and Number of games won = 59.

Step-by-step explanation:

Let x = Number of games lost, y = Number of games won.

y = 13 + 2x    (i)

x+ y = 82    (ii)

Substitute value of y from (i) in (ii) , we get

x+ 13 + 2x  = 82

⇒ 3x= 82-13

⇒ 3x = 69

⇒  x= 23      [Divide both sides by 3]

Put value of x in (i), y= 13+2(23) = 13+46=59

Hence, Number of games lost = 23 and Number of games won = 59.

Solution :

If \(S_n\) is the total spending generated after n transactions, then \(a_n\) is the spending generated during the n-th transaction. Since the government spends D dollars, then \(a_1\) = D.

Then the second person will receive D dollars and spend \(D_c\) dollars. Therefore, \(a_2=D_c\). The next person will receive \(D_c\) dollars, which means they are spending \(a_3 = (D_c)c = Dc^2\) dollars. Therefore,

\(a_1 = D\)

\(a_2=D_c\)

\(a_3 = Dc^2\)

\(a_4 = (Dc^2)c= Dc^3\)

....

\(a_n=Dc^{n-1}\)

∴ \(S_n=a_1+a_2+a_3+....+a_n\)

  \(S_n = D+Dc+Dc^2+Dc^3+...+Dc^{n-1}\)

  \(S_n= D(1+c+c^2+...+c^{n-1})\)

  \(S-n=D . \frac{1-c^n}{1-c}\)

Answer:

1/36

Step-by-step explanation:

So what you have to do is take all the numbers on the dice. Getting a 4 would be a 1 in 6 (1/6) chance, but then you take the risk of rolling again and trying to get another 4. Nothing changes with the amount of sides, so it would just be another 1/6 change to get the 4. Then, you have to multiply the two changes together. SO 1/6 x 1/6 = 1/36. It is a 1/36 chance to role a 4 on both roles.

The probability of an event is a number between  \(0\) and \(1\). Hence, the probability of showing a \(4\) on both the rolls is \(\frac{1}{36}\).

What is probability?

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between  \(0\) and \(1\).

The probability of the first throw  \(4\) is \(\frac{1}{6}\).

And on the second throw is \(\frac{1}{6}\).

For both, the throws probability \(4\) would be

\(\frac{1}{6}\)×\(\frac{1}{6}\)\(=\frac{1}{36}\)

Hence, the probability of showing a \(4\) on both the rolls is \(\frac{1}{36}\).

Step-by-step explanation:

The total volume of the composite figure, which is made up of two congruent rectangular pyramids joined at their bases, is 60 cubed units.

To find the volume of the composite figures,

The composite figure is made up of two congruent rectangular pyramids joined at their bases. 2 congruent rectangular pyramids are connected at their bases.

The volume of a rectangular pyramid is the one third of the product of its length, width and height. Thus, the volume of one pyramid is,

\(V=\dfrac{7.5\times2\times6}{3}\\V=\dfrac{7.5\times2\times6}{3}\\V=30\rm\; unit^3\)

The volume of one pyramid is 30 units³. Both the pyramid is same. Thus, the volume of both pyramid with made the composite figure is,

\(V=30\times2\\V=60\rm\; unit^3\)

An initial investment of $5,951.71 is needed to accumulate $7,000 in 4 years with 2.5% annual interest compounded quarterly.

To determine the amount of money needed to accumulate $7,000 in 4 years with 2.5% annual interest compounded quarterly, we need to use the formula for compound interest.

The formula is A = P(1+r/n)^(nt), where A is the final amount, P is the initial investment, r is the interest rate, n is the number of times compounded per year, and t is the number of years.

Using the given information, we can plug in the values and solve for P. A = $7,000, r = 0.025, n = 4, and t = 4.

A = P(1+r/n)^(nt)

A = P(1+0.025)^4
$7,000 = P(1+0.025/4)^(4*4)
$7,000 = P(1.00625)^16

To calculate the slope between attractions and discover the midpoints, we'll utilize the given requested sets for each fascination. Here are the calculations:

Help Center to Water Slide #1:

Slope = ((y2 - y1) / (x2 - x1)) = ((3 - 3) / (-6 - 2)) = / -8 =

Midpoint = ((x1 + x2) / 2), ((y1 + y2) / 2)) = ((2 + (-6)) / 2), ((3 + 3) / 2)) = (-2, 3)

Toddler area to Concessions:

Slope = ((y2 - y1) / (x2 - x1)) = ((-6 - (-3)) / (6 - (-3)) = (-3 / 9) = -1/3

Midpoint = ((x1 + x2) / 2), ((y1 + y2) / 2)) = ((-3 + 6) / 2), ((-9 + (-6)) / 2)) = (1.5, -7.5)

Gift Shop to Restrooms:

Midpoint = ((x1 + x2) / 2), ((y1 + y2) / 2)) = ((5 + 16) / 2), ((4 + 4) / 2) = (10.5, 4)

Lazy River to Large Whirlpool:

Slope = ((y2 - y1) / (x2 - x1)) = ((10 - 14) / (-7 - 3)) = (-4 / -10) = 2/5

Midpoint = ((x1 + x2) / 2)), ((y1 + y2) / 2)) = ((-7 + 3) / 2), ((10 + 14) / 2)) = (-2, 12)

Presently, let's calculate the linear equations for each case:

Help Center to Water Slide #1:

The Slope is 0, and the y-coordinate is consistent, so the equation is y = 3.

Toddler area to Concessions:

The Slope is -1/3, and the y-intercept can be calculated utilizing the midpoint facilitates:

-7.5 = (-1/3)(1.5) + b

-7.5 = -0.5 + b

b = -7

Gift Shop to Restrooms:

The Slope is 0, and the y-coordinate is steady, so the equation is y = -9.

Security desk to Water Slide #2:
