The candlestick chart to the right shows market action for a
particular stock for five days in September. The lengths of
the candlesticks for September 8 and 11 are approximately
the same. Explain what this means about trading prices on
both of those days.
Answers
The lengths of the candlesticks for September 8 and 11 are approximately the same because this physical object stands in for the price range between the opening and closing prices for that trading day.
The close was lower than the open if the true body is filled in or is completely black. Real bodies that are empty indicate that the close was higher than the open.
Let's consider a case study over a longer time frame, say a week. In this example, the candle records prices from Monday through Friday of the work week. The price at which the market starts on Monday at 9:15 a.m., the first business day of the week, will be the opening price. The highest and lowest prices ever recorded will be set during that particular week.
Over a century before the West created the bar and point-and-figure charts, candlestick charts were invented in Japan. While there was a correlation between rice price and supply and demand in the 1700s, a Japanese man by the name of Homma found that traders' emotions had a significant impact on the markets.
Hence, predict the short-term direction of the price, traders utilise the candlesticks to help them make trading decisions.

Both sets of values have an average of 13. Is Set A's standard deviation smaller, larger, or about the same as Set B's? Set A: 1 2 3 23 24 25 Set B: 9 10 11 14 16 18
a.)About the same
b.)Not enough information provided to tell
c.)Larger
d.)Smaller
Answers
Set A's standard deviation is larger than that of Set B (option c).
What are the standard deviations?
Standard deviation is used to determine how the values in a group differs from the mean of the values in the group. Standard deviation is a measure of variation of a dataset.
In order to determine the standard deviation, take the following steps:
Determine the average of the observation:Determine the difference between each value and the average and then square the result:Determine the average of the sum of the squared differences and then find the square root of the mean:Standard deviation of Set A:
(1 - 13)² + (2- 13)² + (3- 13)² + (23- 13)² + (24- 13)² + (25 - 13)²
144 + 121 + 100 + 100 + 121 + 144 = 730
√730 / 6 = 11.03
Standard deviation of Set B:
(9 - 13)² + (10- 13)² + (11- 13)² + (14- 13)² + (16- 13)² + (18 - 13)²
16 + 9 + 4 + 1 + 9 + 25 = 64
√64 / 6 = 10.67

A probability distribution known as a "normal distribution" is symmetric about the mean and indicates that data that are close to the mean are more likely to occur than data that are far from the mean.
Given that:
μ= 1.4
σ=4.6
We know the formula of normal distribution is z = (x-μ)/σ
[tex]P(0 < x < 3)=P(x < 3)-P(x < 0)[/tex]
For [tex]P(x < 3)[/tex]
[tex]z=\frac{3-1.4}{4.6} \\z=0.35[/tex]

An object is launched from the top of a hill and travels in a parabolic path until it reaches the ground. Write a quadratic function
that models the path of the object with a maximum height of 200 feet, represented by a vertex of (25, 200) , landing at the point
(55.0)
Answers
Answer:
Bonjour,
Step-by-step explanation:
y=k*(x-25)²+200
0=k*(55-25)²+200 => k=-2/9
y=-2/9(x-25)²+200
The a quadratic function that models the parabolic path of the object is y = -2/9(x-25)²+ 200.
What is defined as the parabolic path?A projectile's trajectory angle is defined as a parabolic path. A parabola is just a curve that represents a quadratic equation graphically. The initial velocity of a projectile is either horizontal or upward at such an angle. If a projectile starts out straight up, it will end up straight down. It's not much of a parabola because it's squished into the a straight line.For the given question;
The maximum height of the object which is launched from the top of a hill is 200 m.
The equation of the parabola is -
y=a*(x-h)²+k
(h,k) = vertex = (25, 200)
y = a*(x-25)²+200
Put (x,y) = (55,0)
0=a*(55 - 25)²+200
=> a = -2/9
Now put the value of 'a' and form the equation.
y = -2/9(x-25)²+ 200
Thus, the a quadratic function that models the parabolic path of the object is y = -2/9(x-25)²+ 200.

Step-by-step explanation:
SP is part of a line and line is 180°
so:
m∠PQR + m∠RQS= 180°
(3x-5) + ( x+1) = 4x-4=180
4x = 184
x= 46
m∠PQR = 3X-5 = 3(46)-5 =133
Answer:
133
Step-by-step explanation:
Supplementary angles are angles that sum to 180°, meaning they form a straight line.
Solving for x
Since we know that these 2 angles will sum to 180 (remember they are supplementary) we can add their expression together and set it equal to 180.
(3x-5) + (x+1) = 180Next, combine like terms.
4x - 4 = 180Add 4 to both sides
4x = 184Divide by 4
x=46Solve for m∠PQR
Now that we know the value of x, we can find the measure of PQR. Simply plug 46 in for x and solve.
3(46) - 5 = 133This means that m∠PQR = 133°.

There are 7 pairs of whole numbers that have a sum of 12.
Given that we need to determine the pairs of whole numbers can you find that have a sum of 12.
To find the pairs of whole numbers that have a sum of 12, we can simply list all the possible combinations and count them.
Let's consider two whole numbers, x and y, such that x + y = 12. Since the numbers should be whole numbers and greater than or equal to 0, we have the following options:
x = 0, y = 12
x = 1, y = 11
x = 2, y = 10
x = 3, y = 9
x = 4, y = 8
x = 5, y = 7
x = 6, y = 6
So, there are 7 pairs of whole numbers that have a sum of 12.
These pairs are (0, 12), (1, 11), (2, 10), (3, 9), (4, 8), (5, 7), and (6, 6). Each of these pairs satisfies the condition that both x and y are whole numbers and their sum is equal to 12.
Note: We only consider x and y values up to 6 since beyond that, the sum would exceed 12, and we are only looking for pairs with a sum of 12.
