How do you Evaluate 3f(2)

Which of the following are true if you pay only the minimum amount each month towards your credit card bill? AYou will be charge

faust18 [17]

Answer:

A- You will be charged interest on your remaining balance.

C- You may be in debt for a long time.

Step-by-step explanation:

The following are true if you pay only the minimum amount each month towards your credit card bill:

Firstly one will be charged interest on the remaining amount. Suppose you had a bill of $500. But you paid the minimum of $100. So, you will be charged your standard interest rate on $400.

And with this format, one will be in a debt for a long time as each month some new balance will be added to the previous one.

So, options A and C are true.

B is not true as the interest rates are not changed during the cycle.

Suppose that A is nonsingular. Prove that its inverse A-1 is unique. [Hint: Show that if there exists two matrices, B and C, suc

Bogdan [553]

Answer with Step-by-step explanation:

Let A is non-singular

$\mid A\mid\neq 0$

We have to prove that $A^{-1}$ is unique.

Suppose B and C are inverse of A such that

$BA=I$ and AC=I

By using property $AA^{-1}=A^{-1}A=I$

$C=C$

$(BA)C=B(AC)$

$I\cdot C=B\cdot I$

$C=B$

Hence, the inverse of A is unique.

A random sample of 121 checking accounts at a bank showed an average daily balance of $280. The standard deviation of the popula

klasskru [66]

Answer:

False

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$ .

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

In this problem

Sample of 121, which is higher than 30.

So we do not need to know anything about the shape of the distribution in order to make an interval estimate of the mean of all the account balances.

So the answer is False

Forty tickets at $10.50 each cost?

ANEK [815]

Answer:

This question isn't worded properly but I'll try my best to answer it. What I think you're trying to ask is "How much money would 40 tickets cost?"

Step-by-step explanation:

Well, to make the multipulcation easier you would take away the zero just for now. It should look like this: 4x$10.50=42

Your answer is $42, but then you add the zero back on to that. So now the answer is $420.

<h2>$420 is your final answer</h2>
