Alright, so let's go through each choice.

First off, a checking account is an account at a bank against which checks can be drawn by the account depositor. Or basically, where you can write checks to others.

First answer:

Most checking accounts pay interest on deposits.<span>
</span>True, most banks tend to pay interest on deposits. However, <span>some banks will require that you use direct deposit or maintain a minimum balance. </span>Interest-bearing checking<span>: With an </span>interest<span>-bearing </span>checking account<span>, you are </span>paid interest<span> on the money in your </span>account<span>.</span>

B. When you write a check the bank takes money from your account and pays it to the person who submits the check.

True, this should be a no-brainer. You're paying the person with a check.

C. The bank keeps track of how much money you have left in your account and sends you a statement each month. A charge is usually made for this service

True, this is with almost every bank account.

So, this should be all of the above.

A survey among freshman at a certain university revealed that the number of hours spent studying before final exams was normally
patriot [66]

Answer: 0.0775

Step-by-step explanation:

Given : Mean : \mu = 25

Standard deviation : \sigma =15

Sample size : n=36

Since its normal distribution , then the formula to calculate the z-score is given by :-

z=\dfrac{x-\mu}{\dfrac{\sigma}{\sqrt{n}}}

For x= 28.2 hours

z=\dfrac{28.2-25}{\dfrac{15}{\sqrt{36}}}=1.28

For x= 30 hours

z=\dfrac{30-25}{\dfrac{15}{\sqrt{36}}}=2

The P- value = P(1.28

=P(z

Hence, the probabiliy that the average time spent stydying for the sampe was between 28.2 and 30 hours = 0.0775

Please help!! I’m not sure how to answer this question!!

<h3>Answer:  9V</h3>

=============================================================

Reason:

The volume expression of a cone with radius r and height h is

\frac{1}{3}\pi*r^2*h

Let's plug in the given height h = 12 and we'd get

\frac{1}{3}\pi*r^2*h\\\\\frac{1}{3}\pi*r^2*12\\\\\left(\frac{1}{3}*12\right)\pi*r^2\\\\4\pi*r^2\\\\

This is the volume of the first cone. We're told the first cone has a volume of V, so we can say V = 4\pi r^2

We can't find the actual numeric volume because we don't know what value replaces r. So we leave it as is.

The second cone has the same height (h = 12) but the radius is now 3 times in size. Instead of r, we use 3r

Replace every copy of r with 3r. Then simplify

4\pi*r^2\\\\4\pi*(3r)^2\\\\4\pi*9r^2\\\\9(4\pi r^2)\\\\9V\\\\

The radius tripled which results in a volume that's 9 times bigger.
