Answer:

1/1560

Step-by-step explanation:

The chance of you winning is 1/40, since there are 40 students and you are one of those students. Since, you cannot win again once you win once, you are eliminated. This leaves us with 39 people left. The chances of your friend being chosen out of the 39 people left is 1/39. Now you must multiply 1/40 and 1/39. After multiplying, you get 1/1560.

Answer:

Part A:    We know that 3 bushels is $24, and that rate remains constant, as the graph has a straight line.

Divide both sides by 3 to get 1 bushel=$8.

We can also double check with the other values: 48/6=$8 per bushel, 72/9=$8 per bushel, and so on.

The rate of change is the slope of a line (how much one value changes when the other value does). In this equation, the equation of the line is y=8x, so the slope is 8. Therefore, the rate of change is 8.

Part B:  In the previous year, each bushel of corn was 21/3, 42/6, etc., or $7 a bushel. This year, it is $8, so $8-$7=$1

yKpoI14uk [10]

Answer:

337.406388 or 337 people

Step-by-step explanation:

To figure this out, use the compound interest (compounding number?) equation which is Amount = People(1 + rate)^time

So if you fill that out you get

A = 20,000(.96)^100

A = 20,000(0.0168703194)

A = 337.406388

a population grows at a rate of 6%. if the population is currently 254, write an equation that gives the population x years from
spayn [35]
You will need to use the compound growth formula - this is...
final number = starting number * (multiplier ^ number of years)

We can turn the 6% into a multiplier by dividing it by 100 and adding 1 on to it:
6/100 = 0.06
0.06+1 = 1.06

Then we can say that the starting number is 254 and the number of years is X, we can then place this all into the original formula:
Final population = 254 * (1.06 ^ X)

Hope this helps! :)
