If x=5.25, what is the value of f(x)=10x+8

An Internet and cable-television supplier surveyed a random sample of their customers. The results are shown in the table. A 4-c

Kaylis [27]

Answer:

d. About one-fourth of the cable-television customers are not satisfied.

Step-by-step explanation:

There are 3,141 customers in total, of which 2,032 are internet customers and 1,109 are cable customers.

There are 2,644 satisfied customers, of which 1,820 are internet customers and 824 are cable customers.

There are 497 not satisfied customers, of which 212 are internet customers and 285 are cable customers.

Which statement about the two-way frequency table is true?

a. The survey represents quantitative data.

It is the satisfaction of the customers with the service provided, so it is qualitative data.

b. There is a greater percentage of Internet customers who are not satisfied than cable television customers who are not satisfied.

There are 2,032 internet customers, of which 212 are not satisfied. So 212/2,032 = 10.42% of internet customers are not satisfied.

There are 1,109 cable customers, of which 285 are not satisfied. So 285/1,109 = 25.70% of cable customers are not satisfied.

This statement is not true.

c. About half of the video customers surveyed are cable-television customers.

Of the 3,141 customers surveyed, 1,109 are cable customers. This is 1109/3141 = 35.31%.

This statement is not true.

d. About one-fourth of the cable-television customers are not satisfied.

There are 1,109 cable customers, of which 285 are not satisfied. So 285/1,109 = 25.70% of cable customers are not satisfied.

This is the true statement.

Which expression is equivalent to 10x2y + 25x2?

babymother [125]

$10 x^{2} y +25 x^{2} = 5 x^{2} ( \frac{10 x^{2} y +25 x^{2} }{5 x^{2} }) = 5 x^{2} ( \frac{10 x^{2} y}{5 x^{2} } + \frac{25 x^{2} }{5 x^{2} } ) = 5 x^{2} ( \frac{2y}{1} + \frac{5}{1} )$

Answer A 5x² * ( 2y + 5)

Which equation, when solved results in a different value of x than the other three?

Talja [164]

Answer:

$-\frac{7}{8}(-\frac{8}{7})x-\frac{3}{4}=20(-\frac{8}{7})$

Step-by-step explanation:

The complete question in the attached figure

Verify each case

Part 1) we have

$-\frac{7}{8}x-\frac{3}{4}=20$

solve for x

$\frac{7}{8}x=-\frac{3}{4}-20$

$\frac{7}{8}x=-\frac{83}{4}$

$x=-\frac{83}{4}(\frac{8}{7})$

$x=-\frac{166}{7}$

Part 2) we have

$\frac{3}{4}+\frac{7}{8}x=-20$

Multiply both sides by -1 and rearrange the terms on the left side to get

$-\frac{7}{8}x-\frac{3}{4}=20$

This expression is the same that the expression in Part 1)

That means, that the equations Part 1) and Part 2) are equivalent

therefore

$x=-\frac{166}{7}$

Part 3) we have

$-7(\frac{1}{8})x-\frac{3}{4}=20$

Remember that

$-7(\frac{1}{8})x=-\frac{7}{8}x$

This expression is the same that the expression in Part 1)

That means, that the equations Part 1) and Part 3) are equivalent

therefore

$x=-\frac{166}{7}$

Part 4) we have

$-\frac{7}{8}(-\frac{8}{7})x-\frac{3}{4}=20(-\frac{8}{7})$

This equation is not equivalent to the other three, because some terms are multiplied by -8/7 and others are not. When different things are done on either side of the equal sign, it changes the equation, resulting in a different solution
