Answer:
H.''n is not divisible by 6 and n is not divisible by both 2 and 3.
Step-by-step explanation:
We are given that a statement ''n is divisible by 6 or n is divisible by both 2 and 3.''
We have to write the negation of the given statement.
Negation: If a statement p is true then its negations is p is false.
n is divisible by 6 then negation is n is not divisible by 6.
n is divided by both 2 and 3 then negation is n is not divisible by both 2 and 3.
Therefore, negation of given statement
''n is not divisible by 6 and n is not divisible by both 2 and 3.
Hence, option H is true.
Option A
The simple interest earned over 6 years is $ 4050
<em><u>Solution:</u></em>
Martha invested a principal amount of $15,000 into a savings account that earns simple interest at a rate of 4.5% per year
<em><u>The formula for simple interest is given as:</u></em>

Where, "p" is the principal and "n" is the number of years and "r" is the rate of interest
From given,
p = 15000
r = 4.5 %
n = 6 years
<em><u>Substituting the values we get,</u></em>

Thus simple interest earned over 6 years is $ 4050
