What value for the constant, h, in the equation shown below will result in an infinite number of solutions?
natta225 [31]

Using a system of equations, it is found that a value of h = 4 will result in an infinite number of solutions.

<h3>What is a system of equations?</h3>

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

If two equations are equal, the system has infinite solutions.

In this problem, the equations are:

4x - 16 = h(x - 4).

Then:

4(x - 4) = h(x - 4).

h = 4.

What are the relative frequencies, to the nearest hundredth, of the rows of the two way table?
Nookie1986 [14]

Answer:            A         B

Group A        0.25      0.75

Group B        0.45      0.55

Step-by-step explanation:

Since we have given that

Number of people of A in Group A = 15

Number of people of B in Group A = 45

Number of people of A in Group B = 20

Number of people of B in Group B = 25

Total number of people in Group A = 15+45 = 60

Total number of people in Group B = 20+25 = 45

So, Relative frequencies will be given  below:

Relative frequency of A in Group A is given by

\frac{15}{60}=0.25

Relative frequency of B in Group A is given by

\frac{45}{60}=0.75

Relative frequency of A in Group B is given by

\frac{20}{45}=0.45

Relative frequency of B in Group B is given by

\frac{25}{45}=0.55

Hence,             A         B

Group A        0.25      0.75

Group B        0.45      0.55
