Variables are those unknowns which could have more than one value, and Algebraic expression is an expression that contains numbers, variables(EX, x and y) and Operations (EX,-, +).

This is awfully general. Ruben has or does something. Whatever. Let's call that Whatever "r." Then the expression in question is "r+10."

E^4x– 6 e ^2x – 55=0

WITCHER [35]

Answer:

Hi there!

The answer to this question is: 1.198945

Step-by-step explanation:

Treat eˣ like a "x" if you can temporarily replace eˣ with "x"

so now it's (x²- 11) (x²+6)=0 then replace "x" with eˣ

then you should get e²ˣ = 11 and e²ˣ = -6

next in order to solve for x, you must ln both sides

and you get 2x = ln(11) and you should get 1.198945

****keep in mind: e²ˣ = -6 will be undefined when you ln both sides

What is the mean, median, and standard deviation for the following set of scores: 24, 20, 16, 18, 18, 26, 22? Please show your w

MissTica

Answer:

first: Definitions

mean: the average or the most common value in a collection of numbers

(So u add all numbers and then divide the answer by how much numbers there were)

median: Is middle value.

(example: 4, 5, 6) (The median will be the middle which is 5) (But if there are even amount of numbers like this: 4, 5, 6, 7) (Then you will get the two middle numbers which in this case are 5 and 6 you add them and then divide by 2.)

standard deviation: measures the spread of the data about the mean value

Step-by-step explanation:

Now lets get to problem!

we have numbers:

24, 20, 16, 18, 18, 26, 22

the mean will be: 144 (remember now you have to divide by 7 because there are 7 numbers.)

So it would be 20.57

Now the median:

(Since there are 7 numbers you just find the number in the middle and that would be ur median.)

24, 20, 16, 18, 18, 26, 22

median answer: 18

Like we said: The sample standard deviation measures the spread of a data distribution of the sample. It is usually used to estimate the population standard deviation

So the standard deviation will be: 3.6

I hope this helps :)

What is the twentieth term of the arithmetic sequence described by the<br> equation an= 3n - 10?

sergij07 [2.7K]

Answer:

The twentieth term is 50.

Step-by-step explanation:

The equation that describes the arithmetic sequence describes it's "general term", which means that all the numbers in that sequence must follow that equation. For instance, if we want to find the first term of the sequence we must make a = 1 and we have:

a1 = 3*1 - 10

a1 = -7

Therefore to find the twentieth term we need to make n equal to 20. This is done below:

a20 = 3*20 - 10

a20 = 60 - 10

a20 = 50

The twentieth term is 50.
