Hello there! The formula for finding simple interest is prt. That means multiply the principal (initial amount) by the rate (simple interest percentage) by the amount of time (could be in months or years). In this case, $9800 is the initial amount in the bank and the interest rate is 2% for 15 years. Let’s multiply the numbers. 9800 * 2% (0.02) is 196. That’s $196 a year in simple interest. But it asks for the amount in 15 years, so we multiply those two numbers. 196 * 15 is 2,940. There. $2,940 is earned in interest over 15 years. The answer is A: $2,940.
Answer:
Not a random variable
Step-by-step explanation:
The last book a person read in City A is not a random variable because it is not a number as there is no numerical description for the outcome of this experiment.
Thus, the last book read by someone in City A is not a random variable.
Answer:
Approximately 6.8m
Step-by-step explanation:
We can picture this problem by drawing a rectangular prism with a width of 5m, a depth of 3m, and a height of 3.5m. To find the length from one corner of the floor to the opposite corner of the floor, we can use the pythagorean theorem and plug in the width and depth of the room for a and b:
And now we can solve for c...
c = 5.831m
Now that we have the length from corner to corner across the floor, we can use the pythagorean theorem again, this time using the length from corner to corner across the floor we just derived and the height of the room:
And now we can solve for c again...
c = 6.8m
