What is a counterexample to the conditional statement? If an odd number is greater than 1 and less than 10, then it has no other factors than 1 and itself.

The number 9 is greater than 1 and less than 10, while its factors are 1, 3 and 9, therefore it is a counter example to the statement.

Step-by-step explanation:

There are four odd numbers between 1 and 10, they are: 3, 5, 7 and 9. Let's check the factors for each of them.

For 3:

Therefore 3 is not a counter example to the statement, because it behaves as stated.

For 5:

Therefore 5 is not a counter example to the statement, because it behaves as stated.

For 7:

Therefore 7 is not a counter example to the statement, because it behaves as stated.

For 9:

Therefore 9 is a counter example to the statement, since it can be divided by 1, 3 and 9.

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
