To find the median, find the middle number. Since there are 10 numbers, find the 5th one and the 6th one and find their average.

The two numbers are both 9, so its safe to say that the median is 9.

to find the median of the first and quartile, you have to place a line where the median should be and find the median of that. Q1 and Q2 will be 5 and 11 (respectively).

Its easy to see that all the lines start at the lowest point given and end at the largest point given, so match Q1, the median, and Q3

The only line that has lines at the Q1, median, and Q3 we figured out is answer C, so therefore it is the answer.

If the sin=-3/5 , where cos>0 then what are the values of the remaining trig functions

garik1379 [7]

Now, keeping in mind that, sine is opposite/hypotenuse, and that the hypotenuse is just a radius unit, and therefore is never negative, then, in the fraction of -3/5, the negative values has to be the numerator, not the hypotenuse.

something else to keep in mind is that, cosine > 0, meaning is positive, that only happens in the I and IV quadrants.

since we know the sine is negative, and the cosine is positive, the only place that occurs is on the IV quadrant, so then θ is in the IV quadrant.

$\bf sin(\theta )=\cfrac{\stackrel{opposite}{-3}}{\stackrel{hypotenuse}{5}}\impliedby \textit{now let's find the \underline{adjacent side}}
\\\\\\
\textit{using the pythagorean theorem}\\\\
c^2=a^2+b^2\implies \pm\sqrt{c^2-b^2}=a\qquad 
\begin{cases}
c=hypotenuse\\
a=adjacent\\
b=opposite\\
\end{cases}
\\\\\\
\pm\sqrt{5^2-(-3)^2}=a\implies \pm\sqrt{25-9}=a\implies \pm\sqrt{16}=a
\\\\\\
\pm 4=a\implies \stackrel{IV~quadrant}{4=a}$

$\bf cos(\theta)=\cfrac{adjacent}{hypotenuse}
\qquad 
% tangent
tan(\theta)=\cfrac{opposite}{adjacent}
\\\\\\
% cotangent
cot(\theta)=\cfrac{adjacent}{opposite}
\qquad 
% cosecant
csc(\theta)=\cfrac{hypotenuse}{opposite}
\quad 
% secant
sec(\theta)=\cfrac{hypotenuse}{adjacent}\\\\
-------------------------------\\\\
cos(\theta)=\cfrac{4}{5}\qquad tan(\theta)=\cfrac{-3}{4}\qquad cot(\theta)=\cfrac{4}{-3}
\\\\\\
csc(\theta)=\cfrac{5}{-3}\qquad sec(\theta)=\cfrac{5}{4}$

3. Jennifer writes the letters MONTANA on cards and then places the cards in a hat. What is the probability of picking a v

11111nata11111 [884]

The word Montana has a total of 7 letters this number becomes our denominator because this is the total amount of letters. Three of the letters contain vowels, this number will go on top. These letters include o, and two a (s).

This will give us the answer of 3/7. This fraction cannot be reduced any further.

The answer should result in b.

It appears the slash was forgotten to be written in the answer, try not to make this mistake on any tests!

Hope this helped! :)

Plz Help. write as polynomial -a²(3a-5)+4a(a²-a)

Genrish500 [490]

Answer:

a^3 + a^2

Step-by-step explanation:

Distribute the term left of each set of parentheses, then combine like terms.

-a²(3a - 5) + 4a(a² - a) =

= -3a^3 + 5a^2 + 4a^3 - 4a^2

= a^3 + a^2
