the numbers $1, 2, 3, \dots, 8$ are used once each to form four two-digit numbers. what is the largest number of primes that could possibly be among these four numbers?

The equation of line with slope 3 and y-intercept 6 is y = 3x + 6.

In the given question, we have to find the equation of the line with slope 3 and y-intercept 6.

The slope-intercept version of the line's equation is what we need. In other words, we want y=mx+b in the form of ax+by=c. M is the slope and b is the y-intercept in the slope-intercept form.

From the given question, m = 3 and c = 6.

Now putting the value in the equation y = mx +c

y = 3x + 6

Hence, the equation of the line with slope 3 and y-intercept 6 is y = 3x + 6.

The solutions to both simultaneous equations are;

1) x = -2 and y = -13

2) x = -1 and y = -6

Simultaneous equations are defined as two or more algebraic equations that share variables e.g. x and y

1) The simultaneous equations we have are;

7x - y = -1

-7x + 3y = -25

Using elimination method, add both equations to get;

2y = -26

divide both sides by 2 to get;

y = -13

7x - (-13) = -1

7x + 13 = -1

7x = -14

x = -2

2) The simultaneous equations we have are;

7x - y = -1

7x + 3y = -25

Using elimination method, subtract eq 1 from eq 2 to get;

4y = -24

divide both sides by 4 to get;

y = -6

Therefore , the solution of the given problem of percentage comes out to be she spend $39 on the sandals.

A number or figure that is expressed as a fraction of 100 is known as a percentage in mathematics. There are also sporadic uses of the acronyms "pct.," "pct," and "pc." However, the "%" symbol used to represent it is often employed. No dimensions exist; the % amount is flat. Percentages are essentially fractions because their numerator is 100. A percent symbol (%) should be placed in front of a number to indicate that it is a percentage. For instance, if you answered correctly 75 out of questions in total on a test, you'd get a 75%.

Here,

Given :

Money = $80

Spent 25% on pair of shorts

=> 25/100 * 80 = 20

and

left money = 80 -20 =60

After that she spend 65% on sandals:

The percentage of the data that is less than 76.4 will be 50% if scores of an exam follow an approximately bell-shaped distribution with a mean of 76.4 and a standard deviation of 6.1.

To determine by how many standard deviations the raw score is above or below the mean z score used.

z = (x - μ)/σ

x: raw score, σ: standard deviation, μ: mean

For x = 76.4 points:

z = (76.4 - 76.4)/6.1 = 0

Now, the percentage of data is less than 76.4:

P(x < 76.4) = P(z < 0)

We know that the area is equally distributed around the y-axis.

So, P(z<0) = 50 %

Therefore, the percentage of the data is less than 76.4 will be 50%.

The standard deviation of D= M - T is the measure of the spread of the distribution of D. It is calculated by subtracting the mean of D (uD = 8.6) from each observed value of D and then squaring the result.

The variance is then calculated by summing up all of these squared deviations and dividing by the number of observations. The standard deviation is simply the square root of the variance. In this case, the standard deviation of D is 9.5.

This means that the spread of the values of D is 9.5, which means that Morgan and Tim’s scores are spread out over a range of 19 points.

Dividend ÷ Divisor = Quotient and Remainder

When a dividend is divided by a divisor, we get the value of the quotient in the result.

The result of dividing one integer by another is the quotient. For example, in 8 ÷4 = 2, the division result is 2, hence the quotient is 2. The dividend is eight, while the divisor is four.

The derivative of a quotient is the denominator times the numerator's derivative minus the numerator times the denominator's derivative, all divided by the denominator's square, according to the Quotient Rule.

When dividing one exponential equation by another, we use this rule. We must subtract the exponent in the denominator from the exponent in the numerator using the quotient formula, but the bases must be the same.

If the system is consistent, then the equations must be simultaneously solvable, meaning that there is at least one solution. However, it is possible that there are multiple solutions.

If the system is consistent, then there must be an infinite number of solutions. This is because if a system is consistent, then any values that satisfy the equations can be a valid solution. Therefore, if there is at least one solution, then there must be an infinite number of solutions since there are an infinite number of values that can satisfy the equations.

Furthermore, if the system is consistent, then the equations do not contradict each other and therefore can be solved with any combination of values. Therefore, the system must have an infinite number of solutions.

The effects of the crash were widespread and long-lasting, leading to the Great Depression and causing significant economic and social upheaval.

One of the causes of the stock market crash of 1929 was the overvaluation of stocks, where prices were much higher than the underlying value of the companies. Many investors were buying stocks on margin, which means they were borrowing money to buy stocks, this lead to the overvaluation of stocks. Another cause was the economic policies that favored the wealthy, such as the high tariffs on imported goods and the lack of regulations on the stock market, which allowed for speculation and manipulation.

The effects of the stock market crash of 1929 were far-reaching and long-lasting. One of the most significant effects was the Great Depression, which led to high unemployment, widespread poverty, and significant declines in industrial production and economic activity.
