An auto insurance company pays rebates averaging $86.18 annually with a standard deviation of $6.12 to drivers without an accident for the year. if 2560 drivers received a rebate, what is the expected value and standard deviation for the total rebates given? a) x(expected value)= $204,953.60; sd= $125.17 b)x=204,953.60; sd=$309.65 c)x=$220,620.80; sd=$125.17 d)x=$220,620.80; sd=$309.65

answer: it is d

step-by-step explanation:

false

inverse variation is not exponential

vince wrote the sequence below.

1/3, 1, 5/3, 7/

which of the following explains whether the sequence is geometric?

the sequence is geometric because 2/3 was added to each term to get the next term.

the sequence is geometric because 3 was multiplied to each term to get the next term.

the sequence is not geometric because 2/3 was added to each term to get the next term.

the sequence is not geometric because 3 was multiplied to each term to get the next term.

step-by-step explanation:

x^2 + 10x + 38 + 161/x-4

to find this, you'll need to synthetically divide using synthetic division.

here's how you would set it up:

4 is what you're dividing by (set x -4 = 0)

the numbers you are 'dividing' by are 1, 6, -2, and 9 or the coefficients of the terms listed above.

bring the first term down (1), multiply that by 4 before raising it to the next term to add (6). repeat this process as so:

6 + 4 = 10; 10 x 4 = 40; 40 - 2 = 38 x 4 = 152 + 9 = 161

161 is over x-4 as there are now two constants and you cannot combine them.

also, i'm not sure if it was -9 or +9, so i assumed.

hope this !
