Answer:

  • vertical change: 1 unit
  • horizontal change: 2 units
  • rate of change: 0.5

Step-by-step explanation:

The marks on the graph show the vertical change is 1 unit, and the horizontal change is 2 units.

The "rate of change" is the ratio of vertical change to horizontal change:

  rate of change = slope = Δy/Δx = 1/2 = 0.5

Expressed as a decimal, the rate of change is 0.5.

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.

A triangle has sides with lengths of 60 centimeters, 63 centimeters, and 87 centimeters. Is it a right triangle
lozanna [386]
We can check this by seeing if Pythagorean's theorem applies. The longest side is the hypotenuse, so let's see if this is true:
60^2+63^2 = 87^2
7569 = 7569

This is, indeed correct, thus, this <em>is </em><em>a right triangle.</em>
