To find the mean/data of a set of numbers, add all of the numbers together then divide by the number of numbers there are.

85+93+80+89+92+93+94+91+79 = 796
796/9 = 88.4444444 which can be rounded down to 88.4

The answer is 88.4.

Hopefully this helps! If you have any more questions or don't understand, feel free to DM me, and I'll get back to you ASAP! :)

Given the arithmetic sequence: u(1)= 124, u(2)= 117, u(3)= 110, u(4)=103,...

omeli [17]

We are given

arithmetic sequence: u(1)= 124, u(2)= 117, u(3)= 110, u(4)=103

so, first term is 124

u(1)= 124

now, we can find common difference

$d=u(2)-u(1)$

$d=117-124$

$d=-7$

now, we can find kth term

$u(k)=u(1)+(k-1)d$

now, we can plug values

and we get

$u(k)=124+(k-1)*-7$

$u(k)=124-7k+7$

$u(k)=131-7k$

u(k) must be negative

so,

$u(k)=131-7k$

$131-7k$

now, we can solve for k

$7k>131$

$k>18.714$

so, it's closest integer value is

$k=19$ ..............Answer

angle EPF = angle DPG

=> 4x + 48deg = 7x

=> 3x = 48 deg

=> x = 16

=> angle EPF = 4(16) +48 = 112deg
