The probability and the likelihood, that the marble drawn is not red is high which is 4/5.

To determine how likely something is gonna occur, use probability. Several things are hard to predict with 100% certainty. We can only anticipate the possibility of an event occurring using it, or how likely it is. In the probability scale, 0 indicates an impossibility and 1 indicates a certainty.

It is stated that there is a 2/10 chance of drawing a red marble at random.

We can deduct the likelihood of drawing a red marble from one to determine the likelihood that the drawn marble is not red (since the probability of an event and its complement add up to 1).

So, the probability of drawing a marble that is not red is -

1 - 2/10 = 8/10 = 4/5

Therefore, the probability that the marble drawn is not red is 4/5.

The likelihood of an event is a measure of how plausible it is, given some evidence or knowledge.

In this case, we can say that the likelihood of drawing a marble that is not red is high, since there are more marbles in the jar that are not red than those that are red.

Therefore, the likelihood of drawing a marble that is not red is high.

Step-by-step explanation:

To find the inverse of the exponential function y = (3/2)^x, we need to interchange the roles of x and y, and then solve for y.

So, starting with y = (3/2)^x, we can write:

x = (3/2)^y

To solve for y, we can take the logarithm of both sides with base 3/2:

log(3/2) x = y

Therefore, the inverse of the exponential function y = (3/2)^x is:

y = log(3/2) x

or in exponential form:

y = (log base 3/2) x

This function is the logarithmic function with base 3/2.

The surface formed by the equation 25x²+4y²+z²=100 is an ellipse.

In mathematics, an ellipse is a planar curve with two focus points, where the total of the two distances from any point on the curve to the focal points is a constant. It generalises the shape of a circle, a unique variety of ellipse in which the two focus points coincide. The eccentricity of an ellipse is used to calculate its length.

We may set one of the variables at a constant value and then plot the resulting 2D curve in the plane created by the other two variables in order to sketch the surface. This procedure can be repeated for various constant values to get a rough surface drawing.

An equation in mathematics is a claim made regarding the equivalence of two expressions. It includes one or more variables (unknown values) and describes how those variables and/or constants relate to one another. For instance, the line on a coordinate plane denoted by the equation y = 3x + 5 has a y-coordinate that is equivalent to three times the x-coordinate plus five. Three and five are constants in this equation, while x and y are factors. Finding the value(s) of the dependent variables) that make the equation true is one way to answer an equation. In the example above, we can enter y = 11 into the equation .

given

We must first determine the revenue function, which is provided by, in order to determine the marginal profit at a production level of 3000:

14x - x/1000x = R(x) = xp(x) = 14x - x2/1000

Answer:

Step-by-step explanation:

here are step-by-step explanations for each part of the problem:

A. To find the mean, you add up all of the prices and divide by the number of prices. So:

Mean = (350 + 400 + 500 + 650 + 725 + 850 + 1700) / 7

Mean = 517.86

Rounded to the nearest dollar, the mean is $518.

B. To find the median, you need to put the prices in order from smallest to largest and then find the middle value. In this case, there are seven prices, so the middle value is between the 3rd and 4th prices:

350, 400, 500, 650, 725, 850, 1700

The median is the average of the 3rd and 4th prices, so:

Median = (500 + 650) / 2

Median = 575

The median price is $575.

C. Quartiles divide the data set into four equal parts, so you need to find the values that separate the lowest 25%, the next 25%, the next 25%, and the highest 25% of prices.

To find the quartiles, you can use the following steps:

Put the prices in order from smallest to largest:

350, 400, 500, 650, 725, 850, 1700

Find the median (Q2) as calculated in part B:

Median = $575

Divide the data set into two halves, below and above the median. If the median is included in both halves, exclude it from both.

Lower half: 350, 400, 500, 575

Upper half: 650, 725, 850, 1700

Find the median (Q1) of the lower half:

Q1 = (400 + 500) / 2

Q1 = 450

Find the median (Q3) of the upper half:

Q3 = (725 + 850) / 2

Q3 = 787.5

The four quartiles are Q1=$450, Q2=$575 (median), and Q3=$788.

D. The range is the difference between the highest and lowest values in the data set. So:

Range = highest value - lowest value

Range = $1700 - $350

Range = $1350

The interquartile range (IQR) is the difference between the third quartile (Q3) and the first quartile (Q1). So:

IQR = Q3 - Q1

IQR = $788 - $450

IQR = $338

F. To find the upper boundary for outliers, you add 1.5 times the IQR to Q3. So:

Upper boundary = Q3 + 1.5(IQR)

Upper boundary = $788 + 1.5($338)

Upper boundary = $1282

There are no values above the upper boundary, so there are no upper outliers.

Mark needs a score of 2 on the 5th test to pass the course

Let X be the score Mark needs to get on the fifth test to pass the course.

To find X, we can use the formula for the mean of five numbers:

(mean of 5 numbers) = (sum of the 5 numbers) / 5

We know that Mark needs a mean score of 10 to pass, so:

10 = (total score on all 5 tests) / 5

Multiplying both sides by 5, we get:

50 = total score on all 5 tests

We also know that Mark's mean score on the first four tests is 12, so:

(mean score on the first four tests) = (total score on the first four tests) / 4

12 = (total score on the first four tests) / 4

total score on the first four tests = 48

To pass the course with a mean score of 10, Mark needs a total score of 50, and he has already scored 48 on the first four tests. Therefore, he needs to score:

X = 50 - 48

X = 2

Mark needs a score of 2 on the fifth test to pass the course with a mean score of 10.

Answer: A

Step-by-step explanation:

By answering the above question, we may infer that The inaccuracy, equation when rounded to the closest tenth of a percent, is around 6.6%. The measurement's percent error is 6.6% as a result.

A mathematical equation links two statements and utilises the equals sign (=) to indicate equality. In algebra, an equation is a mathematical assertion that proves the equality of two mathematical expressions. For instance, in the equation 3x + 5 = 14, the equal sign separates the numbers by a gap. A mathematical formula may be used to determine how the two sentences on either side of a letter relate to one another. The logo and the particular piece of software are usually identical. like, for instance, 2x - 4 = 2.

The following formula may be used to get the percent error:

percent error is calculated as follows: 100% divided by (actual value - measured value).

Whereas, "|" stands for absolute value.

In this instance, the measured measurement is 8.5 inches, whereas the real value is 9.1. Hence, by entering these values into the formula, we may obtain:

error = |(9.1 - 8.5) / 9.1| x 100% error = 6.59%

The inaccuracy, when rounded to the closest tenth of a percent, is around 6.6%. The measurement's percent error is 6.6% as a result.

Josslyn burns 7 calories per minute while swimming and 5 calories per minute while practicing yoga. Let x be the number of minutes she spends swimming and y be the number of minutes she spends practicing yoga.

The total number of calories burned, C, is given by:

C = 7x + 5y

To burn at least 500 calories each day, we can write the inequality:

7x + 5y ≥ 500

This inequality states that the total number of calories burned from swimming and practicing yoga, 7x + 5y, must be greater than or equal to 500. Josslyn can achieve this goal by spending a combination of x minutes swimming and y minutes practicing yoga.

As a result, 7 is the number of w that solves the problem.

In mathematics, a denominator is the lowest integer in a proportion that indicates how many equal portions are split into a whole. It is a fraction's division. In this case, the fraction is 4, so there are four components overall.

To solve for w in the equation (W+3)/4 = (W-2)/2, we can start by cross-multiplying to eliminate the denominators:

2(W+3) = 4(W-2)

Expanding the brackets:

2W + 6 = 4W - 8

Simplifying:

2W = 14

W = 7

Therefore, the value of w that satisfies the equation is 7.

What is verbal sentence ?

Verbal sentences consist of a verb + subject + object or adverbial phrase. The subject and object can be either nouns or pronouns.

After solving the equation we get square of n which is equal to three times of eight

If the subject is a pronoun, it is always a suffix; and if the object is pronoun, it is always a dependent pronoun. When the subject is a pronoun, the word order is normal, meaning that the subject follows the verb and precedes the object.

If the subject is a noun and the object is a dependent pronoun, the pronoun object is before the noun subject.

The dative has a special place in the word-order of verbal sentences. It is expressed by the preposition n in addition to a noun or pronoun referring to a person, if the subject is a pronoun. It assumes a third place following the verb and its subject. However, if the subject is a noun, the dative is allocated a forward position and occurs before the subject.

If the subject is a noun and the object is a pronoun and the sentence consists of a dative, the word order is thus:
