Answer:
This is rational because it has two integers
Step-by-step explanation:
IRRATIONAL NUMBER <em>cannot</em><em> </em><em>be</em><em> </em><em>expressed</em><em> </em><em>in</em><em> </em><em>the</em><em> </em><em>form</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>ratio</em><em> </em><em>or</em><em> </em><em>two</em><em> </em><em>integers</em><em> </em>
<em>Example</em>

i got it right on the test !!
Answer: she will make $232.05 in 4 weeks.
Step-by-step explanation:
Since her profit is increasing by 10% each week, then the rate at which it is increasing is in geometric progression. The common ratio, r would be 110/100 = 1.1
We would apply the formula for determining the sum of n terms of a geometric progression which is expressed as
Sn = a(r^n - 1)/(r - 1)
Where
a represents the first term of the sequence.
r represents the common ratio.
n represents the number of terms(number of weeks)
From the information given,
a = 50
r = 1.1
n = 4 weeks
Therefore,
S4 = 50(1.1^4 - 1)/(1.1 - 1)
S4 = 50(1.1^4 - 1)/0.1
S4 = $232.05
Step-by-step explanation:
confidence coefficient for 99% is 2.58
2.58 * 19.4/sqrt(n) = 0.04
2.598*19.4/0.04 = sqrt(n)
( 2.598*19.4/0.04)^2 = n
