$\huge\text{Hey there!}$

$\huge\textbf{What does \boxed{median} mean in math?}}$

$\boxed{\text{Median}}\rightarrow\textsf{ is the number in the middle.}$

$\huge\textbf{How do you find the \boxed{median}?}$

$\text{You can found it by putting the numbers from \bf least to greatest.}$

$\huge\textbf{Question reads....}$

$\text{Find the median for the scores 91, 69, 71, 82, 71, 95, 87, 74, 71, 89, 89, 95,}\\\text{72, 75}$

$\huge\textbf{Equation:}$

$\text{91, 69, 71, 82, 71, 95, 87, 74, 71, 89, 89, 95, 72, 75}$

$\huge\textbf{Rearrange the problems to:}$

$\text{69,71,71,71,72,74,75,82,87, 89,89,91,95,95}$

$\huge\textbf{The expression:}$

$\mathsf{\dfrac{75 + 82}{2} = median}$

$\huge\textbf{Simplify it:}$

$\mathsf{\dfrac{75 + 82}{2} = median}$

$\mathsf{\dfrac{157}{2} = median}$

$\mathsf{257\div2 = median}$

$\mathsf{78.5 = median}$

$\huge\textbf{Therefore, your answer should be:}$

$\huge\boxed{\mathsf{78.5}}\huge\checkmark$

Please help ill give brainliest answer!

LenKa [72]

Answer:

OC=48

RK=100

Step-by-step explanation:

We can use proportions to find both OC and RK.

$\frac{OK}{KY} =\frac{OC}{RY}$

$\frac{12}{24} =\frac{OC}{96}$

$24OC=1152$

$OC=48$

$\frac{KC}{RK} =\frac{OK}{KY}$

$\frac{50}{RK} =\frac{12}{24}$

$12RK=1200$

$RK=100$

First thing to do is set up your equation:
45/x = 20/100
Cross multiply
4500 = 20x
And divide by 20

50 points !! Please help, If you wanna do the work then i'll give brainliest but you dont have to. DO NOT!! I REPEAT DO NOTT!! D

Tasya [4]

-27 divided by 9 = -3, 4 x -6 = -24, 12 x -10 = -120, -45 divided by -5 = 9, 7 x -3 = -21, 72 divided by -8 = -9, 64 dibided by 8 is 8, and -8 x 6 is -48. good luck!! ^_^

1. tan a = cot(a + 10°)

Temka [501]

Answer:

$a=40+90n$

Step-by-step explanation:

Use a cofunction identity on the right hand side or left hand side...

So $\tan(a)=\cot(90-a)$ .

We have the equation:

$\tan(a)=\cot(a+10)$

Make the above replacement:

$\cot(90-a)=\cot(a+10)$

Since cotangent has period 180 degrees, we can also write this as:

$\cot(90-a+180n)=\cot(a+10)$

So solving the following will give us a set of solutions for $a$ :

$90-a+180n=a+10$

Add $a$ on both sides:

$90+180n=2a+10$

Subtract 10 on both sides:

$80+180n=2a$

Divide both sides by 2:

$40+90n=a$

Symmetric property:

$a=40+90n$
