The more times you do a test, the more accurate the results will be.
Since there are only 2 options/sides the probability should be 1/2 for both heads and tails.
Her error was both mathematical (her experimental probability number didn't make sense) and her lack of sufficient testing.
Answer:
6x^3y
Step-by-step explanation:
Step by step solution :
Step 1 :
y
Simplify —
3
Equation at the end of step 1 :
y
((18 • (x2)) • —) • x
3
Step 2 :
Equation at the end of step 2 :
y
((2•32x2) • —) • x
3
Step 3 :
Dividing exponents :
3.1 32 divided by 31 = 3(2 - 1) = 31 = 3
Equation at the end of step 3 :
6x2y • x
Step 4 :
Multiplying exponential expressions :
4.1 x2 multiplied by x1 = x(2 + 1) = x3
Final result :
6x^3y
Basically the answer is going to be 20
So, after one year will will have the new population of 23 000 * (100 %+2%)
(the 100 % is the old population and the 2% is the increase), that is:
23000*1.02=23460
(102 % can be represented as 1.02)
And for the next years, we have to repeat the procedure.
a more generic rule would be:
y=23000*
(x is the number of years passed)

Answer:
C) Peta, because she invests the most
Step-by-step explanation:
The additional $70 that Peta invests is equivalent to more than 2 years' interest at either of the other rates. Not only does Peta invest more money, she does so at a higher interest rate.
Peta will have the most money in her account when she closes it.

The balances will be ...
Joan $490.02
Peta $548.21
Linda $420.00
