The last 5 transactions at mr. brigham's atm were $250, -$60, -$94, $300, and -$186. find the mean transactions amount.

Given

last 5 transactions at Mr. Brigham's ATM were $250, -$60, -$94, $300, and -$186

Find the mean transactions amount

To proof

last 5 transactions were

$250, -$60, -$94, $300, and -$186

FORMULA

mean  of values is the ratio of the sum of all values to the number of all values in the set.

total number of transactions = 5

put all the values in the formula

we get

MEAN = $42

mean transactions amount is  $42

Hence proved

i dont know sorry

step-by-step explanation:

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
