What is the mean of the data set 17,24,26,13

2 answers:

8 0

To find the mean you will have to add all the numbers. And then you will have to divide the sum on the amount of numbers there are.
So you will have to add 17, 24, 26, and 13 which will add up to 80. Now you will have to divide 80 by 4 because there are 4 different numbers so the answer would be 20.

Find the 4th term in the sequence of a(n)=-6-4(n-1)

marishachu [46]

Answer:

a(4) = -18

Step-by-step explanation:

The fourth term in the sequence is when n = 4. Substitute n = 4 into the rule a(n)=-6-4(n-1).

a(4) = -6 - 4(4-1)

a(4) = -6 - 4(3)

a(4) = -6 - 12

a(4) = -18

Do anyone know how to do this?

kykrilka [37]

Answer:

1.) x=4

2.) x=14

Step-by-step explanation:

FOR #1:

1.) In order to solve the parallelogram, you must know that each opposite sides must equal...

so KL=JM and KJ=LM

2.) To solve for "x", you must substitute

$KL= 7x-2\\JM=12x-22$

so it should end up with...

$7x-2=12x-22$

3.) Solve the equation with some algebra

$7x-2=12x-22\\-5x=-20\\x=4$

FOR #2:

1.) In order for a square, rectangle, parallelogram, (or any shape with four sides), it must equal to 360°. And you just have two given angles, which equal to 180, so that means the unknown equals to 180...So in this case you should have

$(3x+5)+(9x-17)+180=360$

as your equation...

2.) Solve with algebra

$(3x+5)+(9x-17)+180=360$

$3x+5+9x-17=180\\12x-12=180\\(\frac{1}{12}) 12x=168 (\frac{1}{12})\\x=14$

multiplied
