An Internet and cable-television supplier surveyed a random sample of their customers. The results are shown in the table. A 4-column table with 3 rows. The first column has no label with entries internet, cable television, total. The second column is labeled satisfied with entries 1,820; 824; 2,644. The third column is labeled not satisfied with entries 212, 285, 497. The fourth column is labeled total with entries 2,032; 1,109; 3,141. Which statement about the two-way frequency table is true? The survey represents quantitative data. There is a greater percentage of Internet customers who are not satisfied than cable television customers who are not satisfied. About half of the customers surveyed are cable-television customers. About one-fourth of the cable-television customers are not satisfied.

step-by-step explanation:

the orientation of the parabolas can easily be found by analysing the power of x and y and their signs. if x is squared , parabola opens up and also if its coefficient is negative it opens down. if y is squared , the parabola opens right and also if its coefficient is negative it opens left. however in order to do the above analysis our equation must be in standard form .

our parabola is

which is not standard form of any parabola . hence we square on both hand side and convert it into standard form.

hence we see that x is squared and its coefficient is non negative . there for it opens up.

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1

the height of the surface increases from the center out to the sides of the road

it is c!
