Answer:
Alaska's coastline is 4.9 times greater than Florida's coastline
Step-by-step explanation:
Let
x ------> Alaska's coastline in thousand miles
y ------> Florida's coastline in thousand miles
we have
The ratio of Alaska's coastline to Florida's coastline is equal to
so
therefore
Alaska's coastline is 4.9 times greater than Florida's coastline
Interest = Pin = principal * interest rate * number of years
Let interest rate be i, then
600*i*2+150*i*4=90
1200i+600i = 90
i=90/(1200+600)=90/1800=1/20=0.05 or 5%
Answer:
1680
Step-by-step explanation:
Since there are 4 places (frames) to put up each poster, we think individually:
In the first place they can place ANY OF THE 8 POSTERS
In 2nd place, they can place ANY OF THE REMAINING 7 POSTERS
In 3rd place, they can place ANY OF THE REMAINING 6 posters
and
in last place, they can place ANY OF THE REMAINING 5 posters
The number of ways is the multiplication of them all, so:
8 * 7 * 6 * 5 ways = 1680 ways
To solve a probability, you need to determine if the order is important or not. The word "<span>If a player can play any position," indicates that the team doesn't need to specify the order. So, the possible way to pick a team of 5 players out of 8 people would be:
8C5= 8!/ 5!</span>(8-5)!=
8C5= 8*7*6/ 3*2=56 ways
8 % = .08 = 8/100 = 2/25
The slope is 2/25
