One year, the population of a city was 189,000. Several years later it was 223,020. Find the percent increase.

Answer:

[tex]p(x) = -0.01x + 15[/tex]

Step-by-step explanation:

Given

Let x represent the number of tickets, and p the charges

[tex](x_1,p_1) = (500,10)[/tex]

A reduction of 50c gives an increment of 50 tickets.

This gives:

[tex](x_2,p_2) = (500+50,10-0,5)[/tex] ---- [tex]50c = \$0.5[/tex]

[tex](x_2,p_2) = (550,9.5)[/tex]

Required

Determine the demand function

First, calculate the slope:

[tex]m = \frac{p_2 - p_1}{x_2 - x_1}[/tex]

[tex]m = \frac{9.5 - 10}{550-500}[/tex]

[tex]m = \frac{-0.5}{50}[/tex]

[tex]m = -0.01[/tex]

So, the equation is:

[tex]p = m(x - x_1) + y_1[/tex]

[tex]p = -0.01(x - 500) +10[/tex]

[tex]p = -0.01x + 5 +10[/tex]

[tex]p = -0.01x + 15[/tex]

Hence, the function is:

[tex]p(x) = -0.01x + 15[/tex]

Answer:

7*6*5*4*3 = 7P5 = 2520

Step-by-step explanation:

There will be 56 points in the sample space when two batteries are selected without replacement from the bag.

To determine the number of points in the sample space when selecting two batteries without replacement, we can use the counting principle.

The counting principle states that if there are m ways to do one task and n ways to do another task, then there are m * n ways to do both tasks together.

In this case, the first battery can be selected in 8 ways (since there are 8 batteries in the bag).

After selecting the first battery, there are 7 remaining batteries in the bag. For the second battery, there are 7 ways to select it (one less than the previous selection).

Therefore, the number of points in the sample space is given by multiplying the number of possibilities for the first selection (8) by the number of possibilities for the second selection (7):

8 * 7 = 56

There will be 56 points in the sample space when two batteries are selected without replacement from the bag.

Answer:

2r = 20

So, r = 10

Step-by-step explanation:

Answer: True

Step-by-step explanation:

A supplementary angle refers to the angles that has a sum of 180° when they're added together.

We should note that a right angle equals to 90°, therefore the other angle in the supplementary angle will be:

= 180° - 90°

= 90°

Since a right angle equals 90°, then the other angle must be a right angle.

Therefore, the answer is TRUE.

Answer:

  C. 7 1/4 units

Step-by-step explanation:

It can be useful to plot the points on a graph.

The two points are on the same horizontal line, so the distance between them is the difference of their x-coordinates.

  4 3/4 -(-2 2/4) = (6 +2) +(3/4 +2/4) = 6 5/4 = 7 1/4 . . . . units

Some folks find it easier to do the arithmetic by converting to decimal numbers.

Answer:

Skewed right

Step-by-step explanation:

Most of the data is to the right, so it's not skewed left.

Uniform is mostly even, so not that either.

Bell shape is centered and vaguely triangular, so incorrect, hence the only remaining option is skewed right.

Hope this helps :)

Answer:

1, 2, 3, and 6 are factors of 6 while 1, 3, 9, and 27 are factors of 27.  Notice that the product of the outer elements equal what your factoring as well as the inners.

1x6=6, 2x3=6, 1x27=27, and 3x9=27.  Notice the GCF in this case is 3, so factor that out of your initial expression.

Therefore 3(2+9) = 6 +

  inverse

  y = 10/x

Step-by-step explanation:

Inverse variation is described by an equation of the form ...

  y = k/x

The value of k is a constant equal to ...

  k = xy = 5·2 = 10·1 = 15·2/3 = 20·1/2 = 10

__

Here, the products of the x- and y-values are all 10, so the inverse variation equation is ...
