PLEASE HELP IM DESPERATE precalculus. also 50 points!! please god help

kompoz [17]

Answer:

For B thru F these options will vary but here how you do it

B. Step 1 Draw the 4 Quadrants.

Then Draw the Triangle in the lower right quadrant which we call quadrant 4. Label the X axis as Adjacent and positive. Label the Y axis as Opposite and negative. Label the Slanted side as the hypotune and AS POSITVE SINCE HYPOTENUSE IS ALWAYS POSITIVE.

FOR C. IN QUADRANT 2, PLOT A POINT AT 0,12 AND AT (-5,0). CONNECT THE DOTS AND IT FORMS A TRIANGLE. Label the X axis as adjacent and negative and the y axis as positve and opposite and label the slanted side hypotunese and positive.

FOR D Draw a straight line along the x axis then draw a slanted line passing through (5,-1). In between them put the theta symbol in there.

The labeling is the same for C.

For E. Since tan must be positve and secant must be positve, our triangle must be in the 1st Quadrant. Draw any right triangle as long it is in the first quadrant

The x axis is adjacent and positve. The y axis is opposite and positve. The hypotenuse is the slanted side and it is positve.

For F. Since sin is negative and cos is positve the triangle is in the 4th quadrant. Draw any triangle in the 4th quadrant and the labeling is the same for Problem B.

2. We can find the sec of cos by flipping cosine.

$\cos( \frac{x}{y} ) = \sec( \frac{y}{x} )$

$\cos( \frac{1}{2} ) = \sec(2 )$

Sec is 2.

To find the cotangent, first let find the sin then tan.

We can use the identity

$\cos( {theta}^{2} ) + \sin( {theta}^{2} ) = 1$

Let plug in the number

$\cos( \frac{ {1}^{2} }{{2}^{2} } ) + \sin(x {}^{2} ) = 1$

$\cos( \frac{1}{4} ) + \sin(x {}^{2} ) = 1$

$\sin(x {}^{2} ) = 1 - \frac{1}{4}$

$\sin(x {}^{2} ) = \frac{3}{4}$

$\sin(x) = \frac{ \sqrt{3} }{ \sqrt{4} }$

$\sin(x) = \frac{ \sqrt{3} }{2}$

Since sin is negative, sin x=

$- \frac{ \sqrt{3} }{2}$

Now let apply the formula

$\frac{ \sin(x) }{ \cos(x) } = \tan(x)$

$\frac{ \frac{ - \sqrt{3} }{2} }{ \frac{1}{2} } = \tan(x)$

$- \sqrt{3}$

Now let find cotangent we can the reciprocal of

tan.

$\tan= - \sqrt{3}$

$\cot = - \frac{1}{ \sqrt{3} }$

Rationalize denominator

$\frac{ - 1}{ \sqrt{3} } \times \frac{ \sqrt{3} }{ \sqrt{3} } = \frac{ \sqrt -{ 3} }{3}$

cotangent equal

$- \frac{ \sqrt{ 3} }{3}$

Which shows a statistical question regarding a data set? A) What is your favorite color? B) What is the total number of eggs in

Gennadij [26K]

Answer: The correct answer is option D: What is the height of the tallest player on a team?

Step-by-step explanation: In statistics generally, you deal with collection of data among other things. In collecting data, for the purpose of arranging and analyzing, you would need to collect data that can be varied, because the variability of the data collected would help in making an analyses that can be used for other similar data. So asking for someone's name for example is not a statistical question, because the answer is as simple as "My name is Brainly."

Hence, asking for someone's favorite color is not a statistical question. The answer is simple and does not require collecting different sets of data.

Asking for the total number of eggs in 5 dozen is a not statistical question because we already know the answer and there is no variability of the data that would be presented in the answer. Each dozen contains the same number of eggs. So its as good as asking what is the total number of eggs in a dozen, or in 10 dozens, and so on.

The total number of ounces in a gallon is also not a statistical question, because just like in option B above, there is no variability of the data that would be collected. The answer is pretty straight forward and that is 128 ounces (of liquid/fluid). There is no variability that would now give rise to analyses of data.

The height of the tallest player on a team is definitely a statistical question, because, <u>there are several players on a team, and their heights normally cannot be same</u>. So asking for the height of the tallest player simply implies that some are taller than the others, and at least one player is taller than all other players. So there will be variability of data in this particular instance, and the data analyst would have different sets of data (players' heights) available to him/her which can be used to draw conclusions
