Marcus invested $2000 in a bank account earning simple interest. The interest, I, he has after t years at an interest rate r is given by this equation.

l = 2000 rt

After 2 years, the total amount in the account was $2160. What was the annual interest rate?

Drag and drop an answer choice into each empty box below

The annual interest rate was

4%
8%
16%
40%

Answers

Answer 1

The answer would be 4%

Answer 2

The value of the annual interest rate will be;

⇒ 4%

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division

Given that;

The invested amount = $2000

And , I = 2000 rt ….(i)

Now,

Since, The invested amount = $2000

⇒ Interest ‘I’ = $2160 - $2000

= $160

Time ‘t’ = 2 years

Substituting these values into;

⇒ 160 = (2000 x 2) r

⇒ r = 0.04

⇒ r = 4%

Thus, the interest r = 4%

Answer: Choice D

Explanation:

To have a function, we cannot have repeated x values. Put another way, we can't have any input go to more than one output. Choices A through C are not functions because....

Choice A has x = 10 go to more than one y output.Choice B has x = 2 go to more than one y output. Choice C has x = 4 go to multiple y outputs.

Only choice D has each x value listed one time. We don't have any repeated x values. Any x input leads to exactly one y output. This is why choice D is a function.

Solve the following and answer if it is true or false - would you flip the sign?

-7n + 6 ≥ -43

True
False

Answers

Let's solve your inequality step-by-step.
−7n + 6 ≥ − 43

Step 1: Subtract 6 from both sides.
−7n + 6 − 6 ≥ −43 − 6 − 7n ≥ −49

Step 2: Divide both sides by -7.
−7n − 7 ≥ −49 − 7n ≤ 7

So, true

true , you first move the constant to the right. and then calculate . and after you divide both sides and flip the sign

A data set has a maximum of 200, a minimum of 115, a median of 145, an upper quartile of 150, and a lower quartile of 120. Which statement is true of the box plot of this data set? The box will go from 145 to 150. A line dividing the box will be at 135. The left whisker will go from 115 to 145. The right whisker will go from 150 to 200.

Answers

Answer:

150 to 200

Step-by-step explanation:

IM DORA

The statement that is true of the box plot of this data set is:

"The right whisker will go from 150 to 200."

Option D is the correct answer.

What is the interquartile range?

An interquartile range is a measure of the difference between the upper and lower quartiles of a dataset.

W can find the values of the upper and lower quartile and median from a box plot.

The middle line is the median and the first line is the lower quartile and the last line is the upper quartile.

The formula used is Upper quartile - Lower quartile.

We have,

The box plot of a data set displays the minimum, maximum, median, and quartiles of the data set.

The box represents the middle 50% of the data, with the median marked by a line inside the box.

The whiskers extend from the box to the minimum and maximum values that are not outliers.

Given the information about the data set, we know that:

The median is 145, which means that the line inside the box will be at 145.

The upper quartile is 150, which means that the top of the box will be at 150.

The lower quartile is 120, which means that the bottom of the box will be at 120.

The minimum is 115, which means that the left whisker will go from 115 to the bottom of the box (which is 120).

The maximum is 200, which means that the right whisker will go from 150 (the top of the box) to 200.

Therefore,

The statement that is true of the box plot of this data set is:

"The right whisker will go from 150 to 200."

Why is it useful to write a ratio of fractions as a unit rate

Answers

Answer:

The unit rate has a denominator of one.This will often modify any subsequent mathematical calculations. Choosing the form of the proportion should really be based on what you're doing with it. Often a denominator apart from 1 is sufficient to follow-up operations that you will need to run.

A "unit rate" has a denominator of 1. That will often simplify any subsequent math operations.
