Based on the graph, is there an association between grade and genre preference?

1 answer:

Answer:

D. There is no association because the distribution of genre preferences is the same among the grade groups

Explanation:

Based on this graph, we can conclude that there is no association between grade and genre preference, because the distribution of genre preferences is the same among the grade groups .

We can see that the 9th and 11th graders have a slightly higher preference for fiction than the 10th and 12th graders. However, this difference is barely noticeable and doesn't affect the conclusion. Most students from every grade prefer fiction to nonfiction, so we can conclude that the genre preference is the same among the grade groups .

The measure of angle zero is 600°. The point XY corresponding to zero on the unit circle is

Andrej [43]

<u>Answer:</u>

$x= -\frac{1}{2}\\\\ y= -\frac{\sqrt{3}}{2}$

<u>Step-by-step explanation:</u>

We are given that the measure of angle θ is 600° and we are to fin the point (x, y) corresponding to angle θ on the unit circle,

We know that the x,y coordinates in the unit circle are the cosine and sine ratios, respectively.

θ = 600

1 unit circle= 360°

It means that 600° corresponds to 600° - 360° = 240°.

So, θ = 360° + 240°

180° < 240° < 270° (this tells that the point is in the third quadrant and its coordinates are negative)

240° - 180° = 60° (using the supplementary angles to find the sin and cos) $\sin 60^\circ = \frac{\sqrt{3}}{2}\\\\\cos 60^\circ= \frac{1}{2}$

Therefore, the x-coordinate is the cos of the given angle while y-coordinate is the sine of the given angle and the coordinates are:

$x= -\frac{1}{2}\\\\ y= -\frac{\sqrt{3}}{2}$

Can someone please help me solve number 13?

oksian1 [2.3K]

If an exponent is negative you need to switch it to the other side.

So it would be 54v¼•w⅔

__________

18v⅔•¹¹/³•x5/7

Then you need to simplify it. So you would do 54÷18 to get 3.

NOTE: when you are simplifying it's dividing, so the answer you get goes where the larger number is. So in this case the 3 is where the 54 was.
