Draw a number line and graph the solution of x < 2

Vera_Pavlovna [14]

You would mark 2 on the number line (open circle) and draw the rest of the line going < that way.

Arrange the following and ascending and descending order first one is 1 by 12 1 by 23 1 by 5 1 by 7 1 by 50 1 by 9 1/17

Nonamiya [84]

Answer:

Ascending order is given by

1/50<1/23<1/17<1/12<1/9<1/7<1/5

Descending order is given by

1/5>1/7>1/9>1/12>1/17>1/23>1/50

Step-by-step explanation:

We are given that

1/12,1/23,1/5,1/7,1/50,1/9,1/17

We have to arrange the numbers in ascending and descending order.

LCM of 12,23,5,7,50,9,17

$23\times 5\times 12\times 7\times 50\times 17\times 9$

=73899000

$\frac{1}{12}\times \frac{6158250}{6158250}=\frac{6158250}{73899000}$

$\frac{1}{23}\times \frac{3213000}{3213000}=\frac{3213000}{73899000}$

$\frac{1}{5}\times \frac{14779800}{14779800}=\frac{14779800}{73899000}$

$\frac{1}{7}\times \frac{10557000}{10557000}=\frac{10557000}{73899000}$

$\frac{1}{50}\times \frac{1477980}{1477980}=\frac{1477980}{73899000}$

$\frac{1}{9}\times \frac{8211000}{8211000}=\frac{8211000}{73899000}$

$\frac{1}{17}\times \frac{4347000}{4347000}=\frac{4347000}{73899000}$

14779800>10557000>8211000>6158250>4347000>3213000>1477980

Therefore,

Ascending order is given by

1/50<1/23<1/17<1/12<1/9<1/7<1/5

Descending order is given by

1/5>1/7>1/9>1/12>1/17>1/23>1/50

If other factors are held constant, which set of sample characteristics is most likely to reject a null hypothesis stating that

EleoNora [17]

Answer:

M = 90 for a sample of n = 100

Step-by-step explanation:

The correct order of the steps of a hypothesis test is given following

1. Determine the null and alternative hypothesis.

2. Select a sample and compute the z - score for the sample mean.

3. Determine the probability at which you will conclude that the sample outcome is very unlikely.

4. Make a decision about the unknown population.

These steps are performed in the given sequence to test a hypothesis.

The null hypothesis is rejected or accepted on the basis of level of significance. When the p-value is greater than level of significance we fail to reject the null hypothesis and null hypothesis is then accepted. It is not necessary that all null hypothesis will be rejected at 10% level of significance or M = 90 with s sample of n = 100. To determine the criteria for accepting or rejecting a null hypothesis we should also consider p-value.

Describe two methods for finding the total price of a bill that includes a 20 tip

Lelechka [254]

One method that I use often is to bounce the decimal point over and multiply by 2. ex/ total is 23.52, bounce the decimal between the 2 and 3 to get 2.30 then multiply by 2 giving you 4.60.

or take the total 23.52 and multiply it by .20 which will give you 4.70

Which graph represents this equation?

madreJ [45]

Graph (A) represents the equation of the line 5y = x + 5 shown in the graph option (A) is correct.

<h3>What is a straight line?</h3>

A straight line is a combination of endless points joined on both sides of the point.

The slope 'm' of any straight line is given by:

$\rm m =\dfrac{y_2-y_1}{x_2-x_1}$

We have the equation of the line:

5y = x + 5

After plotting the line on the coordinate plane.

The above line passes through:

(-5, 0), (0,1), and (5,2)

And the line rises from (-8, -0.5), (-5, 0), (0,1), and (5,2)

Thus, graph (A) represents the equation of the line 5y = x + 5 shown in the graph option (A) is correct.
