If you observe the 4 graphical representations you will see that except stem and leaf plot, the rest 3 represent the same information. 

As the time is increasing, the frequency of students who listen to music is decreasing. The frequency is maximum for the first group 0 - 1 and least for the last group 6 - 7.

The ranges shown in both Frequency Table and Histogram are the same. 

So, the following options are correct:
<span>B) One of the displays does not show the same information as the others.
C) The first three displays show that as time increases, frequency decreases.</span>

8x-2(x+1)=2(3x-1)<br> A. 0<br> b.2<br> C.no solution <br> D.identity
fomenos

8x - 2x(x+1) = 2(3x-1)

First, expand to remove parenthesis. / Your problem should look like:

8x - 2x - 2 = 6x - 2

Second, subtract 8x - 2x -2 to get 6x - 2. / Your problem should look like:

6x - 2 = 6x - 2

Third, both sides are equal, so there are infinite solutions. The equation is always true, meaning identity


Answer: Infinite solutions

What’s the answer for this?
fgiga [73]

Answer:

1.98

Step-by-step explanation:

Use SOH-CAH-TOA:

Sine = Opposite / Hypotenuse

Cosine = Adjacent / Hypotenuse

Tangent = Opposite / Adjacent

Here, we're given the hypotenuse is 4.5, and we want to find the side opposite of the 26° angle.  So we should use sine.

sin 26° = x / 4.5

0.44 = x / 4.5

x = 1.98
