I would accept the offer. If you count a dollar a second, for 8 hours, you can count up to 8×60×60 or 28800 dollars each day. The 7 days a week part is not needed to calculate since that means you can count for 8 hours for each day of the week. To count 1 billion dollars with 28800 dollars a day, it would take about 34722.22... days to count it all, or about 95.12 years to count every last dollar. The thing is, the question never said I had to count or use it all, so I would use as much as I needed, counted the receipt, and left the rest.
1) fractions equivalent to 25/45
Any fraction obtaining by multiplying both numerator and denominator by the same quantity will result in an equivalent fraction.
Examples:
- divide both numerator and denominator by 5 => 5/9 is equivalent
- multiply both numerator and denominator by 2 => 50 / 90 is equivalent
- multiply both numerator and denominator by 10 => 250 / 450 is equivalent.

<span>Spinning two fours on a spinner divided into four numbered sections: these are independent events, becasue one result does not influence the other.
Selecting two kings from a standard deck of cards by choosing a card at
random, placing it in your pocket, then choosing the second card: they are not independent, because if the first card is a king the probability of the second card will be different than if the first card is not a king.
Selecting two green marbles by choosing one from a bag at random, giving the first to a friend, then choosing another: they are not independent because whether the first two marbles are green or not, make the probabilities for the second event different.
Selecting the names of two siblings by choosing slips of paper from a
hat at random, pinning the selected slip on a bulletin board, and then
selecting another.: they are not independent, by similar reason explainded in the two previos options.</span>
Answer:
a=20; b=-12
Step-by-step explanation:
if you just say (20,-12) then a can anything it can be 20 or it can be -12 so (a=20; b=-12) is an organized way of keeping it.
Answer:
no
Step-by-step explanation:
Answer:
y = 1/3x - 7/3
Step-by-step explanation:
y2 - y1 / x2 - x1
-1 - (-3) / 4 - (-2)
2/6
= 1/3
y = 1/3x + b
-1 = 1/3(4) + b
-1 = 4/3 + b
-7/3 = b
