the card "axis" needs to be moved to the first column, the card with the plain grid on it in the second column needs to be moved to the third column, and the card that says "(7,2)" needs to be moved to the second column

Answer:

She will earn 150$

Step-by-step explanation:

4% = 0.04

0.04 x $625 = 25

Now we divide 25 by the number of years, which is 6.

6 x 25 = 150$

Therefore, Skye earns 150$ from interest over the course of 6 years.

Answer:

the higher the magnitude, the the lower the frequency.

Answer: A is yes. B is no, C is yes

Step-by-step explanation: The reason A is yes, is because the terms are 27b, 12b and 4 because they are separated. The reason B is no, is because the like terms are 27b and 12b because their variables are alike. The reason C is yes, is because 27b+12b=39b+4 is an équation simplified.

Using it's concept, it is found that the probability of spinning an odd number, not flipping heads, then not spinning a 6 is:

[tex]p = \frac{20}{81} = 24.69\%[/tex]

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this problem:

Then, the probability of the compound event is:

[tex]p = \frac{5}{9} \times \frac{1}{2} \times \frac{8}{9} = \frac{20}{81} = 24.69\%[/tex]

The type of graph that allows you to compare the frequency of intervals, but not the frequency of exact values is a stem-and-leaf plot.

An histogram is a graphical representation of a data distribution, which uses bars or bins to represent the frequency of the data distribution that are in intervals.

Similarly, in dot plot the total number of dots tells us the total number of observations of the values of that thing we did.

The Stem and leaf plot is to show the data distribution while retaining its uniqueness which shows the raw values by retaining the original data,

The type of graph that allows you to compare the frequency of intervals, but not the frequency of exact values is a stem-and-leaf plot.

Therefore, the graph used to show data in intervals is: B.a stem-and-leaf plot

Answer:

5625 feet

I hope it's helps you

Answer:

5625 feets

Step-by-step explanation:

Rate(feet/seconds) = height(feets)/time(seconds)

175 = x/25

x = 4375

After the skydiver opens his parachute the height reduces

Initial height – reduced height

10000 – 4375

= 5625 feets

Answer:

B

Step-by-step explanation:

I am not sure what your teacher wants but I guess you can say the following:

at n = 1, the cost is 4 dollars.

at n = 2, the cost is 8 dollars.

This trend is the same where the cost increases by 4 as n increases by 1. This means the C = 4n. We can check this by plugging values into the equation.

For the first row, C = 4, n = 1, and so the equation satisfies it. For the second row in the table, C = 8, n = 2, and so the equation works again. The other data points also agree using the equation.    

Answer:

Function 1: None of the Above

Function 2: Quadratic

Function 3: Linear

Step-by-step explanation:

Function 1: It isn't linear because the y-axis doesn't go up or down at a constant rate, it isn't quadratic because it doesn't have a vertex, and it isn't exponential because it doesn't continue going up.

Function 2: It has a vertex-(6,32)

Function 3: The y-axis goes up at a constant rate of 6.

Step-by-step explanation:

The system of equations needed to solve the given equations is . Thus, the correct graph is the top-right graph. Its plotted below.

How to find the system of equations needed to solve an equation?

An equation usually consists of equality of two mathematical expressions. Let it be

�

=

�

A=B . If we take them to be equal to third variable, then:

�

=

�

=

�

A=B=C type of equation is obtained.

We can then take it as system of two equations as:

�

=

�

�

=

�

A=C

B=C

Solution to this system will give us the solution to the considered equation

What is a solution to a system of equations?

For a solution to be solution to a system, it must satisfy all the equations of that system, and as all points satisfying an equation are in their graphs.

For the given case, we are given that:

Plotting these two functions on the X-Y plane, the common point of these curves is the common value which can satisfy both the equations simultaneously, and thus, being the solution to the considered system of equations.

Thus, the solutions are those two points that are intersections of those two curves.
