Which measure of central tendency best describes this situation: the favorite color of a class of kindergarteners? Explain. Mode

Jet001 [13]

Mode because the data are not numerical.

The median cannot be found because you can not place the colors from lowest to highest in value. There's no way to determine order.

The mean can not be used because you can't add up the colors and divide by the total colors.

The point (-3/5,y)in the third quadrant corresponds to angle θ on the unit circle.

anastassius [24]

The given point (-3/5 , y) lies in the third quadrant.
It is also given that the point lies on a unit circle.

For a point (x,y) lying on a unit circle a and y are defined as:

x = cos θ
y = sin θ

So, we can say for the point (-3/5 , y) the value -3/5 is equal to cos θ

sec θ is the reciprocal of cos θ.

So, sec θ = -5/3

$cot\theta= \frac{cos\theta}{sin\theta}$

Using Pythagorean identity we can first find sin θ.

$sin \theta = - \sqrt{1- cos^{2}\theta } \\ \\ 
sin\theta= \sqrt{1-( -\frac{3}{5})^{2} }=- \frac{4}{5}$

Since the point lies in 3rd quadrant, both sin and cos will be negative.

So, now we can write:

$cot\theta= \frac{ \frac{-3}{5} }{ \frac{-4}{5} } \\ \\ 
cot\theta= \frac{3}{4}$

Answers:
sec θ = -5/3
cot θ = 3/4

Factor this expression plz ...<br> 14r - 8

grandymaker [24]

Answer:

2 ( 7r - 4 )

Step-by-step explanation:

14r - 8

To factor this expression, you must pull the factor 2 outside the expression by basically reversing the distributive property:

14r - 8 = 2 ( 7r - 4 )
