In Wednesday, the stock market had its biggest loss.

Over the course of a day, the stock market will fluctuate in value due to a number of factors. These include political news and economic data. Over the first four days of the week, this means that Monday through Thursday there is more volatility because these are typically the busiest trading days for stocks.

10.45 - (-18.75) = +29.2

-34.75 - (10.45) = -45.2

-40.89 - (-34.75) = -6.14

On Wednesday the stock value lost -45.2 of its value.

When the stock market loses value, it is usually because there are concerns about a company's future prospects. This can be due to changes in the business environment, new technologies that negatively impact the company's performance, or regulatory issues.

Hence, the stock market lost its most value on Wednesday .

Step-by-step explanation:

1 purple bead for every 12 pink beads

The length of each side of the box is 10 centimeter.

Volume is the amount of space occupied by a three-dimensional figure as measured in cubic units.

Given,

The volume of the cubic box = 1 liter

We know 1 liter= 1000 cubic centimeter

Volume of the cubic box= [tex]x^3}[/tex]

Then,

[tex]x^{3}=1000\\ x=\sqrt[3]{1000}[/tex]

x=10 centimeter

Hence, the length of each side of the box is 10 centimeter.

If Lisa's father randomly pick a tie among his 16 ties, the probability it will be a blue one is 3/8

Probability is a measure how likely an event will happen. The probability of an event A is defined as the number of event A divided by the number of all possible outcomes. Mathematically,

P(A) = n(A)/n(S)

Where:

n(A) = number of event A

n(S) = number of all possible outcomes or sample space.

In the given problem:

Number of all ties = 16

Number of blue ties = 6

Hence, when a tie is picked up randomly, the probability it will be a blue one is:

P(blue) = (number of blue ties) / (number of all ties)

P(blue) = 6/16 = 3/8

Answer:

number of years worked, salary, salary, number of years worked, M(x)=4,000x+60,000, M(9)=96,000, switch your very last answer

Step-by-step explanation:

The dependant veriable depends on whatever the independent variable is.

Ryan was offered a job after college earning a salary of $60,000. He will get a raise of $4,000 after each year working for the company.

In this problem, the dependant variable is the salary, because his salary depends on the number of years he's worked.

If you think about it as if it's really happening, it'll make more sense--the longer you work at a job, the more raises you'll get over time.

To put this into an equation, we have to use slope-intercept form: y=mx+b

y is the same as M(x), m is your dependent variable, x is your independent variable, and b is the amount you start with.

Then we just plug the numbers in:

the dependant variable is 4000, independent is the years (which we don't need yet, so it stays as x) and the amount he will start with is 60000

M(x)=4,000x+60000

for M(9), you just plug 9 into x and solve

M(9)=4,000(9)+60000=96,000

Finally, 9 years after being hired, his salary will be 96000 (dollars? I don't know what answer goes here but what you put doesn't really fit)

I really hope I didn't explain that too badly or completely wrong because it's been a bit since I learned this so sorry, but fun fact, I remember doing this exact delta math, and I also remember hating it so good luck

Answer:

(-4, 4)

Step-by-step explanation:

x can be either negative 4 or positive 4.  A negative number squared is a negative number times a negative number, which will be a positive number.

The number of years that the population has doubled will be 33 years.

Consider the function:

y = a (1 + r) ˣ

Where x is the number of times this growth/decay occurs, a = initial amount, and r = fraction by which this growth/decay occurs.

A little town had a population of 2.53 thousand upon its founding. The population increases by 2.15% annually. Then the equation will be

y = 2.53(1.0215)ˣ

The number of years that the population has doubled will be

2 × 2.53 = 2.53(1.0215)ˣ

2 = (1.0215)ˣ

x ln1.0215 = ln2

x = 32.58 ≈ 33 years

The number of years that the population has doubled will be 33 years.

If a group of 5 adults and 8 children, went for a ride of the Ferris wheel, and if the ticket cost $1 per person, irrespective of age, then total cost of tickets for the whole group will be $13.

As per the question statement, a group of 5 adults and 8 children, went for a ride of the Ferris wheel and the ticket costed $1 per person, irrespective of age.

We are required to calculate the total cost of tickets for the whole group.

Since the ticket cost was same for persons of all ages, therefore, total members of the group who wanted to ride the Ferris wheel was

(8 + 5) = 13.

As per the Unitary method, we have to calculate the value of 13 tickets from the data on the value of a single ticket provided to us in the question statement, i.e., we simply need to multiply the number of tickets with the cost of a single ticket to obtain our desired answer.

Therefore, cost of 13 tickets with each ticket costing $1 is [tex](13*1)=13[/tex] Dollars.

The distance between the coordinates G(8, -2) and H(-1, 4)is; 10.82

We are given the two coordinate points as;

G(8, -2) and H(-1, 4)

The formula to find the distance between these two given coordinates is;

d = √[(x2 - x1)² + (y2 - y1)²]

Plugging in the relevant values gives;

d = √[(-1 - 8)² + (4 - (-2))²]

d = √(81 + 36)

d = √117

d = 10.82

Thus, the distance between the coordinates G(8, -2) and H(-1, 4)is; 10.82

Final answer:

The student's mean score in the class is calculated as 80.6

The average of a group of variables is referred to as the mean in mathematics and statistics. There are several methods for calculating the mean, including simple arithmetic means (adding the numbers together and dividing the result by the number of observations), geometric means, and harmonic means. The mean represents the average or middle value of all the data in a dataset as a single number. One of many measures of central tendency, it is also referred to as the arithmetic average.

The mean is significant because it reveals the location of the dataset's median value. Because it contains data from each observation in a dataset, the mean is also significant.

Explanation:

Let [tex]x1 = 62, x2 = 83, x3=91, x4=88, x5=76[/tex]

Test scores count for 20% of the grade, final grades for 25%, and homework grades for 15% of the grade. Therefore

[tex]w1 = w2= w3 = 0.20\\w4 = 0.25\\w5 = 0.15[/tex]

[tex]= > \frac{12.4 + 16.6 + 18.2 + 22+11.4}{1}[/tex]

Which becomes,

[tex]= 80.6[/tex]

According to weights proportionate to values in the final grade, the weighted mean yields the mean value. The observed values are multiplied by the weights, which are then divided by the total number of weights.
