You are given the following list of values: 5.8, 6.1, 4.9, 10.9, 0.8, 6.1, 7.4, 10.2, 1.1, 5.2, 5.9 Which values are outliers?

Answers

To find the outlier your have to find the IQR( interquartile range), the upper fence and the lower fence. The IQR is the difference between the first and third Quartile. Q3(7.4) -Q1(4.9)= 2.5. Use the IQR to find the Upper fence and Lower fence.
Upper fence- (7.4)+1.5(2.5)= 11.15
Lower fence- (4.9)-1.5(2.5)= -1.15
Make sure your values are in the right order so you can see what numbers are below or above the Upper and lower fences. There are no outliers.

A circular plate has circumference 29.5 inches. What is the area of this plate? Use 3.14 for pi.

Answers

The circumference is given by the formula:

C = 2 pi r

In this case, we are provided with C, but not r, so we must make r the subject

29.5 = 2 x 3.14 x r

Divide by 2 x 3.14 to get r by itself

r = 4.69745.... (don't round off yet!)

Now that we found r, let's use the formula for the area of a circle,

A = pi r^2
= 3.14 x (4.69745...)^2
= 69.3 in^2 (1 dp)

Hope this helped!

Final answer:

To find the area of a circular plate with a given circumference, use the formula A = πr², where A is the area and r is the radius. Set up the equation for the circumference of the plate and solve for the radius. Then, plug the radius into the formula for the area. This gives the area as 69.07 inches².

Explanation:

To find the area of a circular plate, we can use the formula A = πr², where A is the area and r is the radius. In this case, the circumference of the plate is given as 29.5 inches. We know that the circumference of a circle is equal to 2πr, so we can set up the equation 29.5 = 2πr to solve for the radius.

Dividing both sides of the equation by 2π, we get r = 29.5 / (2π). Using the value of π as 3.14, we can calculate the radius as r ≈ 4.69 inches. Now we can plug this value into the formula for the area: A = 3.14 × (4.69)². Evaluating this expression gives us the area of the circular plate as A ≈ 69.07 inches².

a day care center charges a $75 enrollment fee plus $100 per week which of the following represents the cost of sending a child to daycare for 14 weeks?

Answers

Answer:

cost of sending a child to daycare for 14 weeks is $1475

Step-by-step explanation:

a day care center charges a $75 enrollment fee plus $100 per week

LEt x be the number of weeks

cost of sending a child to day care = 100x + 75

To find the cost for 14 weeks, we plug in 14 for x

cost = 100(14) + 75= 1400+75 = 1475

cost of sending a child to daycare for 14 weeks is $1475

What is the difference in the sum of the exterior angles measures of a rectangular nonagon and a rectangular dodecagon?

Answers

The sum of the exterior angles of ANY polygon = 360 degrees.So, the difference = 360 - 360 = 0.

The sum of the exterior angles of any polygon is 360 degrees, thus the difference between the sums of the exterior angles of a nonagon and a dodecagon is 0 degrees.

The question asks about the difference in the sum of the exterior angle measures of a nonagon and a dodecagon. The key concept here is that for any polygon, the sum of the exterior angles is always 360 degrees, regardless of the number of sides.

Therefore, the sum of the exterior angles of both a nonagon (9-sided polygon) and a dodecagon (12-sided polygon) would be 360 degrees each. Consequently, the difference in their sums would be 0 degrees.

QUANTITY EQUATION:
x + y= 24

VALUE EQUATION:
3x + 5y= 100

If we solved these two equations by elimination or substitution, we find x and y. I'm going to solve by elimination.

STEP 1:
multiply the quantity equation by -3 to eliminate the x variable and solve for y.

-3(x + y)= -3(24)
-3x - 3y= -72

STEP 2:
add the value equation and the step 1 equation together to eliminate the x term and solve for y.

3x + 5y= 100
-3x - 3y= -72
the x term is eliminated

2y= 28
divide both sides by 2

y= 14 5-point questions

STEP 3:
substitute the y value into either original equation

x + y= 24

x + 14= 24
subtract both sides by 14

x= 10 3-point questions

Final answer:

To solve the problem, create a system of linear equations representing the sale of necklaces and bracelets. The two equations will be 15n + 5b = 50 and n = 0.5b, which describe the total funds raised and the relationship between the number of necklaces and bracelets sold.

Explanation:

Niona is trying to raise $50 for her school trip by selling necklaces and bracelets. We need to establish a system of linear equations to represent the problem. Let's define n as the number of necklaces and b as the number of bracelets. According to the problem, Niona sells necklaces for $15 each and bracelets for $5 each, and she sells half as many necklaces as bracelets.

Therefore, we can write the first equation based on the total amount of money raised:

15n + 5b = 50

And the second equation based on the relationship between the number of necklaces and bracelets:

n = 0.5b

Solving this system will give us the number of necklaces and bracelets Niona needs to sell to raise $50 for her trip.

What unit would you use to measure a kite string

Answers

inchesssssssssssssssssssssssssssssssssssssssss

Final answer:

To measure a kite string, one would typically use meters or feet, and the most suitable tool for this measurement would be a tape measure.

Explanation:

The unit you would use to measure a kite string is typically a unit of length. When we discuss the measurement of length for everyday objects such as kite strings, we commonly use units like meters, centimeters, or feet. For a kite string, which can be quite long, meters or feet are the most practical units. You would tie the string to the mass (kite) at one end and to the handle or spool at the other, and measure the length, L, of the string. The tool most suitable for measuring such lengths would be a tape measure, as it can be extended along the length of the string and is flexible enough to be used in various situations.

The steps below show the incomplete solution to find the value of x for the equation
5x − 2x − 3 = −2 + 15:

Step 1: 5x − 2x − 3 = −2 + 15
Step 2: 5x − 2x − 3 = 13
Step 3: 3x − 3 = 13

Which of these is most likely the next step?

3x = 16
3x = 10
3x = 39
3x = 3

Answers

3x = 16 you need to get 3x by itself so you can divide so add the 3 to the other side

3x - 3 = 13

The next step will be to add 3 to both sides:
3x - 3 + 3 = 13 + 3

⇒ 3x = 16

Answer: 3x = 16

The lock on a safe requires a three-digit code to open it. The three digits must each be a number from 0-9 (10 possible numbers). Each number cannot be used more than once in the code. How many codes could there be?

A.1,000
B.720
C.30
D.120

Answers

The correct answer is Choice B: 720.

To solve this, you have to use the Fundamental Counting Principal. You find the total number of options for each of the digits, then multiply them together.

For the first one, there are 10 options, then 9 options and finally 8 options.

10 x 9 x 8 = 720

Final answer:

This problem can be solved through permutation in mathematics. Without repetition, with 10 possible digits (0-9), there are 10 choices for the first digit, 9 for the second, and 8 for the third. The total number of 3-digit codes is 10*9*8 = 720.

Explanation:

The subject of this question is combinations in mathematics. To solve it, you have to calculate the number of ways you can arrange 3 digits from 0-9 (10 digits), when each digit can only be used once.

This problem is a type of permutation (an ordering or arrangement of objects), specifically a permutation without repetition. With 10 possible digits (0-9), there are 10 choices you can make for the first digit. After the first digit is chosen, there are 9 digits left for the second place, and 8 digits left for the third place.

Therefore, the total number of possible 3 digit codes is calculated as follows: 10*9*8 = 720. Hence, "option B is the correct answer".

a plane can travel 480 miles per hour with the wind and 440 miles per hour Against the Wind find the speed of the wind and the speed of the plane in still air

Answers

wind speed = x

planes speed with wind: 480-x
planes speed against wind: 440+x
set them to equal and solve for x ( wind speed)

480-x = 440 +x

add x to each side:

480 = 440 +2x ( x+x=2x)

480 = 440 +2x
subtract 440 from each side:

40 = 2x

divide both sides by 2
x = 40/2
x = 20

wind speed = 20 miles per hour

speed of plane in still air = 480-20 = 460 miles per hour

Final answer:

The speed of the plane in still air is 460 miles per hour, and the speed of the wind is 20 miles per hour, found by setting up equations using the given speeds with and against the wind and solving them.

Explanation:

The question requires us to find the speed of the wind and the speed of the plane in still air based on the given speeds of the plane traveling with and against the wind. The speed of the plane with the wind is 480 miles per hour, and against the wind is 440 miles per hour. We can use these values to set up two equations:

The plane's speed in still air plus the wind's speed equals 480 mph.

The plane's speed in still air minus the wind's speed equals 440 mph.

Let's denote P as the plane's speed in still air and W as the wind's speed. We can establish two equations based on the aforementioned points:

1. P + W = 480

2. P - W = 440

To find P and W, we add the two equations together:

(P + W) + (P - W) = 480 + 440

2P = 920

P = 920 / 2

P = 460 mph

Now that we have the plane's speed in still air, we can find the wind's speed using either of the original equations:

460 + W = 480

W = 480 - 460

W = 20 mph

Therefore, the speed of the plane in still air is 460 miles per hour and the speed of the wind is 20 miles per hour.

1. Using the formula for the probability of one event or another event, calculate the probability of drawing a card from a standard deck that is either a jack or a club. Write out the formula and show your work. Write the final answer as a fraction in simplified form. (10 points)

Bonus question for extra credit: What is the probability of drawing two cards from a deck, without replacing the first card, and either getting two red cards or two aces? Hint: the probability of getting two aces is the probability of the first card being an ace, times the probability of the second card being a different ace. Show your work, and write your answer as a fraction in reduced form.

Answers

A standard deck has 52 cards.
A standard deck has 4 jacks.
A standard deck has 13 clubs.

From this, we can derive the following:
The probability of drawing a jack is 4/52 or 1/13
The probability of drawing a club is 13/52 or 1/4

But since the problem asks for drawing jack or club, therefore we should add the 2 probabilities, making 17/52. This is not the final answer yet. We know that there is a jack of clubs, therefore we need to subtract 1 from the probabilities since jack of clubs were considered in the 2 categories of probability.

With that being said, the probability of drawing a club or a jack is 16/52 or 4/13

Bonus Question:

The first thing you need to do here is find the probability of each scenario. First let's do what is given, the probability of drawing 2 aces. Since there are 4 aces in a deck of 52, we can easily say that the probability of drawing an ace is 4/52. However for our second draw, the probability of drawing a different ace is 3/51. This is so since we already drew a card that is an ace, hence we need to subtract one from the total aces (4-1) and from the total cards in the deck (52-1). In getting the probability of drawing two aces, we need to multiply the said probabilities: 4/52 and 3/51, resulting to 1/221.

For the second scenario, the drawing of 2 red cards, we just use the same concept but in this, we are already considering the 2 red cards in the first scenario, therefore the chance of drawing a red on our first draw is 24/52. For our second, we just need to subtract one card, therefore 23/51. Multiply these two and we will get 46/221.

Now, the problem asks for the chance of drawing either 2 reds or 2 aces, therefore we add the probabilities of the 2 scenarios:
46/222 + 1/221 = 47/221

Summary:
First Scenario:
4/52 + 3/51 = 1/221
Second Scenario:
24/52 + 23/51 = 46/221
Chances of drawing 2 red cards or 2 aces:
1/221 + 46/221 = 47/221
