Front

What is the value of 10^0?

Back

1

Front

If a dog weighs 18 pounds and gains 2 3/4 pounds each year, how many years ago was it bought if it now weighs 34 1/2 pounds?

Back

6 years ago

Front

In an experiment where a coin is flipped 100 times and lands on heads 55 times, what is the experimental probability of getting heads?

Back

0.55

Front

A spinner is divided into 4 equal sections labeled A, B, C, and D. If section A is landed on 15 times after 40 spins, how does the experimental probability compare to the theoretical probability of landing on A (1/4)?

Back

The experimental probability is higher than the theoretical probability.

Front

What percent of 50 is 20?

Back

40%.

Front

Define experimental probability.

Back

Experimental probability is the ratio of the number of times an event occurs to the total number of trials.

Front

What is the formula for calculating percent?

Back

Percent = (Part/Whole) x 100.

Front

What is the theoretical probability of landing on section A in a spinner divided into 4 equal sections?

Back

1/4.

Front

If a dog gains 2 3/4 pounds each year, how do you convert this to an improper fraction?

Back

2 3/4 = 11/4.

Front

How do you calculate the total weight of the dog after 6 years if it started at 18 pounds?

Back

Total weight = Initial weight + (Weight gain per year x Number of years) = 18 + (11/4 x 6) = 34.5 pounds.
