Answer:  430000

Step-by-step explanation: you have to do pemdas

Answer: 430,000. /four hundred thirty thousand

Step-by-step explanation:

The value of 4.3 x 10^5 is 430,000.

To understand this, the notation 4.3 x 10^5 represents a number in scientific notation, where 4.3 is the coefficient or significand, and 10^5 is the exponent. The exponent of 10 tells us how many places to move the decimal point to the right. In this case, the exponent 5 means we need to move the decimal point five places to the right.

Starting with 4.3, we move the decimal point five places to the right to get 430,000. So, 4.3 x 10^5 is equivalent to 430,000.

A line's slope might be zero, positive, negative, or undefinable. The slope of a horizontal line is zero because it does not climb vertically (y1 y2 = 0), but the slope of a vertical line is unknown because it does not run horizontally (x1 x2 = 0).

The slope (m = 3.5 is positive) and y-intercept (b = 4) of the line y = 3.5x + 4 are both positive. This indicates that the y-intercept, or point (0, 4), is where the line crosses.

A line on a plane with no upward or downward slope is known as a line with zero slope in mathematics and computer science.

So the probability of getting four cards of the same rank and one other card is approximately 0.00096, or about 1 in 1,040.

Probability is a measure of the likelihood or chance of an event occurring. It is a numerical value between 0 and 1, where 0 indicates that the event is impossible and 1 indicates that the event is certain to occur. The probability of an event happening can be calculated by dividing the number of favorable outcomes by the total number of possible outcomes. For example, the probability of rolling a six on a fair six-sided die is 1/6, because there is only one favorable outcome (rolling a six) out of six possible outcomes (rolling a one, two, three, four, five, or six). Probability theory is widely used in mathematics, statistics, physics, engineering, economics, and many other fields to model and analyze uncertain situations and make predictions based on incomplete or imperfect information. It has many practical applications, such as in insurance, gambling, risk assessment, and scientific research.

Here,

To calculate the probability of getting four of a kind and one other card, we need to count the number of possible hands that satisfy this condition and divide it by the total number of possible hands.

First, we need to count the number of possible hands that contain four of a kind and one other card. There are 13 ranks in a deck of cards, and for each rank, there are 48 ways to choose four cards of that rank and 4 ways to choose one card of another rank (there are 4 cards of each rank in a deck). Therefore, the total number of hands that contain four of a kind and one other card is:

13 x 48 x 4 = 2,496

Next, we need to count the total number of possible hands of five cards that can be chosen from a deck of 52 cards without replacement. This is given by the formula:

52 choose 5 = 2,598,960

Therefore, the probability of getting four of a kind and one other card is:

2,496 / 2,598,960 = 0.00096 (rounded to 5 decimal places)

THE minimum score required to be in the top 4% of exam scores is 87.08 points, which is option A. To determine the minimum score required to be in the top 4% of exam scores, we can use the standard normal distribution and the Z-score formula.

First, we need to find the Z-score associated with the top 4% of exam scores. The Z-score represents the number of standard deviations above or below the mean a particular value falls. We can use a standard normal distribution table or calculator to find that the Z-score corresponding to the top 4% is approximately 1.75.

Next, we can use the Z-score formula to find the minimum score required to achieve a Z-score of 1.75:

Z = (X - μ) / σ

where X is the minimum score required, μ is the mean of exam scores, and σ is the standard deviation of exam scores.

Rearranging the formula to solve for X, we get:

X = Z {multiply} σ + μ

Plugging in the values we have, we get:

X = 1.75 {multiply}6.1 + 76.4

X = 87.08

Therefore, the minimum score required to be in the top 4% of exam scores is 87.08 points, which is option A.

Note that this assumes that the distribution of exam scores is approximately normal, which is often the case for large samples. If the sample size is small or the distribution is significantly non-normal, this method may not be as accurate.

Completing the square is a mathematical technique used to manipulate quadratic equations into a standard form that makes them easier to solve

The general form of a quadratic equation is:

ax^2 + bx + c = 0

To complete the square, you need to add and subtract (b/2a)^2 to the left side of the equation. This is because (b/2a)^2 is equal to (b/2a) times itself, which means it is a perfect square.

Here is the formula for completing the square:

ax^2 + bx + c = 0

ax^2 + bx = -c

a(x^2 + (b/a)x) = -c

a(x^2 + (b/a)x + (b/2a)^2 - (b/2a)^2) = -c

a(x + b/2a)^2 = -c + (b/2a)^2

The equation is now in the standard form:

a(x + b/2a)^2 = (4ac - b^2)/4a

By taking the square root of both sides, you can solve for x:

x = (-b +/- sqrt(b^2 - 4ac))/2a

This is the quadratic formula, which gives you the values of x that make the equation equal to zero.

The lengths of the missing sides are: y = 7.0 * sqrt(2) and x = 7.0 * sqrt(2)

Triangle can be defined in which it consists of three sides, three angles and sum of three angles is always 180 degrees.

According to the 45-45-90 triangle theorem, the two legs of a 45-45-90 triangle are congruent and the hypotenuse is the square root of 2 times the length of the legs. Therefore, if the side opposite the 45-degree angle is 7, then the other leg is also 7.

Let's label the hypotenuse as h. We know that h is the side opposite the right angle, so h = x. Using the Pythagorean theorem, we can find the length of x:

[tex]x^2 = 7^2 + 7^2x^2 = 98x = sqrt(98) = 7.0 * sqrt(2)[/tex]

So the length of the hypotenuse is 7.0 * sqrt(2).

Now let's find the length of the side opposite the other 45-degree angle, which we'll label as y. Since the two legs are congruent, y is also equal to 7.0 * sqrt(2).

Therefore, the lengths of the missing sides are: y = 7.0 * sqrt(2) and x = 7.0 * sqrt(2)

The selling price of the motorcycle is Rs 1,19,400. To calculate this, we can use the formula Selling Price = Original Price - (Original Price × Loss Percentage).

In this case,

To calculate the selling price of an item when a loss percentage is given, we first need to calculate the amount of the loss. This can be done by multiplying the original price by the loss percentage. Then, we subtract the loss amount from the original price to get the selling price.

In this example, the original price of the motorcycle was Rs 135000, and the loss percentage was 12%. Multiplying 135000 by 0.12 gives us a loss amount of 16200, and subtracting this from 135000 gives us a selling price of 119400.

By question-

The income plainness of demand measures the responsiveness of the volume demanded of a good or service to a change in income, all other effects being equal .However, it means that the good is a normal good, and the volume demanded increases as income increases, If the income plainness is positive. However, it means that the good is an inferior good, and the volume demanded diminishments as income increases, If the income plainness is negative.

In this case, John's pay increased by 20 percent, and the average number of eatery reflections he consumed increased from one a week to three a week. We can calculate the income plainness of demand for eatery reflections as follows

Income plainness = chance change in volume demanded/ chance change in income

The chance change in volume demanded is

( 3 reflections per week- 1 mess per week)/ 1 mess per week) x 100 = 200

The chance change in income is 20

thus, the income plainness of demand for eatery reflections is

Income plainness = 200/ 20 = 10

From the question, we are to determine the measures of the unknown angles in the triangle.

From the diagram, we can observe that the triangle is an isosceles triangle as the legs of the triangle are congruent to each other.

Since the triangle is an isosceles triangle, the base angles of the triangle must be equal

The base angles are 46° and x°

Thus,

x = 46

Also,

We can write that

y° + 46° + x° = 180° (Sum of angles in a triangle)

y° + 46° + 46° = 180°

y° + 92° = 180°

In the triangle QRS, the length of QS is 12 inches

Triangles are a fundamental shape in geometry, and understanding them is critical for many mathematical calculations.

In this case, triangle QRS and XYR are similar triangles, so we can use the ratio of XY to XR to calculate the length of QS.

Mathematically, this ratio can be expressed as:

=> XY / XR = QS / QY.

Thus, if we plug in the values of XY (8 inches) and XR (5 inches) into the equation, we get:

=> 8 / 5 = QS / 12.

We can then solve for QS by multiplying both sides of the equation by 12 and dividing by 8. This gives us the following result:

The probability that at most 12 out of 20 randomly chosen people in NYC who have COVID have the XBB.1.5 variant is approximately 0.2277 and the probability that one must test 8 or more COVID patients in order to find exactly 5 that have the XBB.1.5 variant is approximately 0.9987.

(a) Let X be the number of people out of 20 who have the XBB.1.5 variant. X follows a binomial distribution with parameters n=20 and p=0.7. We need to find the probability that at most 12 out of 20 randomly chosen people in NYC who have COVID have this specific variant, which can be expressed as P(X ≤ 12).

Using a binomial distribution table or a calculator, we can calculate:

P(X ≤ 12) = ΣP(X=k), for k=0 to 12

P(X ≤ 12) =  0.2277

Therefore, the probability that at most 12 out of 20 randomly chosen people in NYC who have COVID have the XBB.1.5 variant is approximately 0.2277.

(b) Let Y be the number of patients tested until exactly 5 are found to have the XBB.1.5 variant. Y follows a negative binomial distribution with parameters r=5 and p=0.7. We need to find the probability that one must test 8 or more COVID patients in order to find exactly 5 that have the new variant, which can be expressed as P(Y ≥ 8).

Using the negative binomial distribution formula, we can calculate:

P(Y ≥ 8) = ΣP(Y=k), for k=8 to infinity

P(Y ≥ 8) = Σ [(k-1) choose (r-1)] p^r (1-p)^(k-r), for k=8 to infinity

This is a tedious calculation to do by hand, but we can use a calculator or software to find that P(Y ≥ 8) ≈ 0.99872
