Katie is at a casino and bets on only the face cards (J, Q, and K). The casino dealer deals Katie a card from a 26-card deck that contains only clubs and spades. What is the probability that Katie will win this round?

Answers

To answer this question accurately, one must understand the fact that there would be a total of 6 face cards in the cards deck of 26 cards. Three face cards will be from clubs and 3 will be from spades.
Then
Probability that Kate will win this round = 6/26
                                                              = 3/13
I hope the procedure is clear enough for you to understand.
(J,K,Q) clubs, (J,K,Q) spades...she is only betting on 6 cards...out of 26.

6/26 reduces to 3/13

Recently, a random sample of 25–34 year olds was asked, "How much do you currently have in savings, not including retirement savings?" The following data represent the responses to the survey. Approximate the mean and standard deviation amount of savings.

A random sample is the arbitrary selection of data in a non-preselected form.

What is Sampling Error?

This refers to the statistical error which is made when a researcher fails to select a sample which represents a population.

With this in mind, we can see that if a person is studying standard deviation or mean of a set of data and has a sampling error, then it would not give an accurate reading of the set of data.

Please note that your question is incomplete so I gave you a general overview to help you better understand the concept.

Answer:

You forgot to put the data

Step-by-step explanation:

Because we  don't have the data that represent the responses to the survery I can show you how to can get the mean and the standard deviation.

The mean is the average of the numbers. We use it to get a representative value of the data we are manipulating.  We calculate it by adding all the numbers and then divide the sum by how many numbers we have.

The formule we use is:

The standard deviation is a measure of the variation or dispersion of the data we have. A low deviation indicates that our data is few disperced, on the other hand a big deviation indicates a high dispersion of the data.

The formule we use is:

A games shop sells marbles in clear plastic cylinders.
Four marbles fit across the
diameter of the cylinder, and
10 marbles fit from the base
to the top of the cylinder.
Each marble has a diameter
of 2 cm. What is the area of
the plastic that is needed to
make one cylinder?

Answers

To start, the question is asking for surface area of a cylinder, meaning you will have to use this formula to find it: A=2πrh+2πr^2.

Since you already know that the diameter of the plastic cylinder is 4 marbles long, and each marble is 2 cm in diameter, you would multiply 4 and 2 to get that your diameter is 8 cm. However, since the surface area of a cylinder formula uses radius, you would simply divide 8 by 2 to get that the radius of the cylinder is 4 cm. 

Now, since you already know that the height of the cylinder is equal to 10 marbles, multiply the amount of marbles by 2 to get that the height of the cylinder is 20 cm. 

Now that you know the height and the diameter of the cylinder, plug the values into the formula: A=2π(4)(20)+2π(4)^2.
Assuming that pi is 3.14, simplify the equation as according to PEMDAS and you get that the area of plastic needed to make one cylinder is 602.88 cm squared

The cage is 4 feet tall, 22 inches, wide, and 2 yards long. What is the volume of the cage in cubic inches?

Answers

Step One
Convert all the non inch measurements to inches.

4 feet [ 12 inches / 1 foot] = 48 inches      [The feet as units cancel]
22 inches = 22 inches. No conversion needed.
2 yards [ 3 feet / yard ] * [ 12 inches / foot ]  = 72 inches.

Step Two
Find the volume

V = L * W * H
V = 48 * 22 * 72
V = 76032 cubic inches.
Convert everything to inches.
4 ft × 12 = 48 in
2 yds × 36 = 72 in

Multiply 48 × 22 × 72 = 76032.

The volume of the cage is 76,032 in³.

WOWOWOWOW, I'M LOSING BRAIN CELLS. Well, when you said 0.93 I don't know if you mean 0.93% or 93% so I'm going to take both cases in mind. If it was 93% then the probability would be 77.5% and if it was 0.93% then the probability would be 0.775%. YOU'RE WELCOME :)
