I hope this helps! Please mark me brainliest, I really need it because I got scammed multiple times. Please help!

Step-by-step explanation:

If all the scores of the students were the same, and the mean is 7.8, that means everyone got 7.8 (the mean is the most common number). I hope this helps! Please mark me brainliest, I really need it because I got scammed multiple times. Please help!

Answer:

7.8

Step-by-step explanation:

If all the scores of n students are the same, say x, then the average is

x*n/n, which is of course x.

Solve the following equation on the interval [0,2 \pi) Cot(3x)=\sqrt{3}

Orlov [11]

Cot(3x)=3^(1/2)

cot(x)= cos(x)/sin(x)

cot(3x)= cos(3x)/sin(3x)

look at a unit circle chart

find a value for cos that has sqrt(3) in it

which one will reduce so that the cos/sin will equal sqrt(3)?

pi/6 radians

now cot(3x) implies that x is one third this value

pi/18 is the answer

Find the inverse of each function. Is the inverse a function? f(x)=x⁷

Luda [366]

The inverse of the function x^7 is x^-7 and it is also a function.

An inverse function or an anti function is defined as a function, which can reverse into another function.

A standard method to find inverse of a function is to set y=f(x)

let y= f(x)=x^7

thus

$\sqrt[7]{y}$ =x
