Which data outcome of stock prices would best support the idea that there is more risk with that stock?
High mean with high standard deviation
Low mean with high standard deviation
High mean with small standard deviation
Low mean with small standard deviation

Answers

Answer 1

High mean with High standard Deviation is the data outcome of stock prices would best support the idea that there is more risk with that stock.

Stock Price:

The stock price is the price of one share out of the number of shares available for sale in the company. Simply put, stock price is the maximum amount someone is willing to buy a stock, or the minimum amount someone is willing to buy.

High mean with High standard Deviation:

A high standard deviation literally means a large mean deviation from the mean. For example, a good dart his player can throw darts on the dartboard and group the darts across the bullseye. A poor darts player will hit the entire board with the darts and even miss the board completely and hit the wall. A good darts player has a smaller average distance from the bullseye to the dart, and therefore a lower standard deviation. Bad darts players have a higher standard deviation because the average distance of their darts from the bullseye is greater.

There are no objective criteria for small and large standard deviations. We can only determine whether the mean deviation is small or large, depending on the context and what is being measured. For example, when throwing a dart, being one foot away from the target is a large deviation, but when swinging a wrecking ball against a wall, it is a small deviation. It has a different purpose than darts.

steve has three quarters, three nickels and three pennies. if steve selects three coins at random and without replacement, what is the probability that the total value is exactly $35$ cents? express your answer as a common fraction.

Answers

Steve has three quarters, three nickels and three pennies. if Steve selects three coins at random and without replacement, then the probability  that the total value is exactly 35 cents is 0.107.

Probability:

Probability is the branch of mathematics that deals with numerical descriptions of the likelihood of an event occurring or the likelihood of a statement being true. Probability is a number between 0 and 1, with 0 generally indicating impossibility and 1 indicating certainty that an event will occur. A simple example is tossing a fair (unbiased) coin. Since the coin is fair, the two outcomes (heads and tails) are equally likely. The probability of heads is the same as the probability of tails. Since no other outcome is possible, the probability of heads or tails is 1/2.

Probability without Replacement:

Probability without replacement means that once you draw an item, you don't put it back into sample space before drawing a second item. In other words, an item cannot be drawn more than once. For example, if he takes one candy out of a box containing nine candies and does not replace the first one, he takes the second one. Of course, the rehearsal room for the second event no longer stays at 9 because we didn't replace the first candy. So the second event has a sample space of 8. That is, the sample space of the second event has changed.

According to the Question:

The only way you can get 35 cents is with 1 quarter and 2 nickels    

There are 3 ways to pick up a quarter  ³C₁

and there are 3 ways you can pick up 2 nickels : ³C₁

Thus,

There are  3× 3 = 9 ways to choose 1 quarters and 2 nickels.

That is 9 favorable outcome.

Now,

there are ⁹C₃ = 84 ways to choose 3 coins from 9  

Therefore,

the probability of picking up 35c is    

9/84

= 3/28

= 0.107

A business owner invested $7,000 in a treasury bond paying 4.3% compounded semiannually. After 30 years, the value of the bond will be $25,084.20. If the business owner's investment was compounded continuously instead of twice per year, what would be the difference in the account balance after 30 years?

Answers

The difference in the account balance after 30 years is $345.31.

What is compounded continuously?

Theoretically, continuously compounded interest means that an account balance continuously earns interest as well as reinvesting that interest into the balance so that it too earns interest.

Given:

A business owner invested $7,000 in a treasury bond paying 4.3% compounded semiannually.

After 30 years, the value of the bond will be $25,084.20.

The business owner's investment was compounded continuously instead of twice per year.

We have to find the difference in the account balance after 30 years?

Consider, the compounded continuously formula,

[tex]A = Pe^r^t[/tex]

Plug p = 7000

r = 4.3% = 0.043

t = 30

⇒ [tex]A = 7000e^(^0^.^0^4^3^*^3^0^) = 25429.51[/tex]

A = $25429.51

So, the difference is, $25429.51 - $25084.20 = $345.31

Hence, the difference in the account balance after 30 years is $345.31.

How do you find the axis of symmetry of an absolute value function?

Answers

An absolute value graph has one axis of symmetry that passes through the vertex.

From the preceding graph, it can be seen that when the coefficient of x increases, the v form moves closer to the line of symmetry and vice versa.

However, it is not always the case that the symmetry line and the y-axis coincide.

For instance:

A line of symmetry for the equation -y=|3x-6|-5 runs parallel to the y-axis and through the x-axis.

You must be aware of the location of the graph's vertex and the line of symmetry.

To obtain the value of x, which will be the x coordinate for the vertex of the graph, take the equation inside the absolute value and equal it with 0. Then, replace the value of x with the main equation to obtain the y coordinate for the vertex of the graph.

The probability of drawing three green marble, with replacing them, is 61/100.

Given,

A bag contains four red marbles, six green marbles, eight yellow marbles, and two blue marbles.

We need to find the probability of drawing three green marble and replacing them.

A combination is used to select required items from a set where the order of selection does not matter.

It is given by:

n^Cr = n! / r! (n-r)!

Where n = the number of elements present in a set.

Find the number of each marble.

Red marbles - 4

Green marbles - 6

Yellow marbles - 8

Blue marbles - 2

Find the probability of drawing a green marble

P (G) = ^6C_1 / ^20C_1

         = (6!/1!)/(20!/19! 1!)

        = 720 / 20

P(G)= 36

Find the probability of drawing a yellow marble

P ( Y ) = ^8C_1 / ^20C_1

         = (8! /1! 7!) / (20! / 191 1!)

         = 8 / 20

        P ( Y ) = 2 / 5

Find the probability of drawing a blue marble

P ( B ) = ^2C_1 / ^20C_1

         = (2! / 1!) / (20! / 19! 1!)

         = 2 / 20

  P ( B )= 1/10

Find the probability of drawing a blue marble

P ( R ) = ^4C_1 / ^20C_1

         = (4! / 1!) / (20! / 19! 1!)

         = 24 / 20

P ( R ) =6/5

Find the probability of drawing a green marble, replacing it, then drawing a yellow marble

Both the probability is independent so,

P = P ( G ) X P ( Y )+P ( G ) X P ( R )+P ( G ) X P ( B )

 = 36 X 2 / 5+36 X 6/5+36 X1/10

P= 61/100

Thus the probability of drawing three green marble, and replacing them, is 61/100.

a) Sketch the quadrilateral on graph paper
b) Write an equation in y = mx + b form for each of the sides
c) Determine which type of quadrilateral it is using the equations and your sketch to explain

Answers

The quadrilateral given is Parallelogram.

What are Quadrilaterals?

Quadrilaterals are four sided polygons which also have four vertices and four angles.

Sum of all the interior angles of a quadrilateral is 360 degrees.

(a) The quadrilateral is sketched as shown in the graph below.

(b) We have to write the equation of four lines AB, BC, CD and AD in the form y = mx + b. m is slope and b is intercept along Y axis.

Coordinates of vertices are A(-5, 2), B(-2, 6), C(3, 5) and D(0,1).

Equation of line AB :

Slope = (6 - 2) / (-2 - -5) = 4/3

Equation in point slope form is

(y - 2) = 4/3(x - -5)

y - 2 = 4/3 x + 20/3

y = 4/3 x + 26/3

Equation of line BC :

Slope = (5 - 6) / (3 - -2) = -1/5

Equation in point slope form is,

(y - 6) = -1/5 (x - -2)

y - 6 = -1/5 x - 2/5

y = -1/5 x + 28/5

Equation of line CD :

Slope = (1 - 5) / (0 - 3) = -4/-3 = 4/3

Equation in point slope form is,

y - 5 = 4/3 (x - 3)

y - 5 = 4/3 x - 4

y = 4/3x + 1

Equation of line AD :

Slope = (1 - 2) / (0 - -5) = -1/5

Equation in point slope form is,

y - 1 = -1/5 (x - 0)

y - 1 = -1/5 x

y = -1/5 x + 1

(c) Opposite sides are having the same slope.

From the sketch, opposite sides are equal.

So quadrilateral is either parallelogram or rectangle.

But if the figure is rectangle, adjacent sides are perpendicular and therefore the product of their slope is -1.

But it is not the case here.

So it is parallelogram.

Hence the given figure is a parallelogram.

a blackjack dealer lays out five cards, face down, from a single deck of 52 cards. what is the probability that at least one of them is an ace?

Answers

0.6928 or 69.28% is the probability of at least one ace among five cards .

in order to get the probability that at least one of the five cards is an ace, then we implement the use of  complement rule.

as we know this rule states that the probability of an event happening  which is equal to 1 minus the probability of the event  which is not happening.

In this order of situation the event is drawing no aces from the five cards. hence the  probability of drawing no aces is (48/52)^5, as we are having   48 non-ace cards in the deck and the value of the  probability of drawing a non-ace is 48/52.

the calculation to get the probability of drawing at least one ace is:

1 - (48/52)^5 = 1 - (0.9231)^5 = 0.6928

hence  the probability value  of at least one ace among five cards is 0.6928 or 69.28%.

b) Write a system of equations for the situation.

Answers

Answer:

a) Let x be the number of bags of snacks supplied, and y be the number of beverages supplied.

b) We know that the total number of items supplied is the sum of the number of bags of snacks and the number of beverages, so we can write:

x + y = 400

We also know that the number of beverages supplied is 50 more than the number of bags of snacks, so we can write:

y = x + 50

Therefore, the system of equations for the situation is:

x + y = 400

y = x + 50

52
130
a. Find two corresponding sides. Use them to create a scale factor ratio. Include units! (1)
b. Use your ratio to set up equivalent fractions and find the height of the backhoe. (2)

Answers

Analyzing the figure given in the question,

a.

  1. The corresponding sides are ,

    Side with length 52'' in small triangle and Side with length 130'' in      bigger triangle      Height of the person i.e 6ft and height of the backhoe.

  2. The scale factor ratio is , 2.5.

b. The height of the backhoe is 180''.

What are corresponding sides of a triangle?

Corresponding sides of a triangle are the sides of a triangle that are in the same position relative to the vertices of the triangle. In other words, they are the sides of the triangle that are opposite to the same angles.

What are similar triangles?

If two triangles have an equal number of corresponding sides and an equal number of corresponding angles, then they are comparable. Similar figures are described as items with the same shape but varying sizes, such as two or more figures.

From the given figure,

length of base of the small triangle, let a = 52 inches

length of base of the bigger traingle, let b = 130 inches

height of the person , let c = 6ft = 6*12 inches = 72 inches

height of the backhoe, let d = ?

a.

Since the smaller and bigger traingles are similar triangles we can equate the proportion of corresponding sides ,

b/a = d/c = 130/52=2.5 -------- equation 1

Therefore the required scale factor is 2.5

b.

Using the 2nd ratio in equation 1,

d/c = 2.5

or, d/72 = 2.5

therefore, d = 180 inches

therefore the required height of the backhoe is 180 inches.

We have to given that;

A regular hexagon has six congruent sides.

And, The length of each side is represented by the expression (7x + 4).

Now, We know that;

The sum of all sides of a regular hexagon is called its perimeter.

Hence, We get;

Here, The length of each side is represented by the expression 7x + 4.

So, We get;

The perimeter of Hexagon = 6 × (7x + 4)

                                          = 42x + 24

if the mean of a population is 250 and its standard deviation is 20, approximately what proportion of observations is in the interval between each pair of values?

Answers

If the mean of a population is 250 and the standard deviation is 20, we can say that approximately 68% of observations fall between 230 and 270, 95% of observations fall between 210 and 290, and 99.7% of observations fall between 190 and 310.

It's important to note that these percentages are approximate and based on the assumption that the population follows a normal distribution.

The normal distribution is a continuous probability distribution that is symmetric about the mean. The standard deviation (σ) is a measure of the spread of the data. Approximately 68% of the observations fall within one standard deviation of the mean, 95% of observations fall within two standard deviations of the mean, and 99.7% of observations fall within three standard deviations of the mean.
