Andre can make 6 small cranes. X is the number of small cranes, 3x is the minutes, 10 is the minute for large cranes and 30 is the total time.
3x + 10 is less than or equal to 30
3 is the minutes for the small cranes
X is the number of small cranes
10 is the minutes for the large crane
30 is the total time limit
first, subtract 10 from 30, ( 30-10) which gives you 20 so
3x is less than or equal to 20.
To figure this out, divide 20 by 3, which gives you 6 as a quotient with a remainder of two minutes.

Suppose that 6 out of the 19 doctors in a small hospital are General Practitioners, 5 out of the 19 are under the age of 40 , and 2 are both General Practitioners and under the age of 40. What is the probability that you are randomly assigned a General Practitioner or a doctor under the age of 40
The probability of randomly selecting a doctor who is either a General Practitioner or under the age of 40 from a small hospital is 9/19, given 6 out of 19 are General Practitioners, 5 out of 19 are under 40, and 2 are both.
To find the probability of randomly selecting a doctor who is either a General Practitioner or under the age of 40, we need to add the probabilities of these two events and subtract the probability of selecting a doctor who is both a General Practitioner and under the age of 40, since we don't want to count that case twice:
P(General Practitioner or under 40) = P(General Practitioner) + P(Under 40) - P(General Practitioner and under 40)
we know 6 out of 19 doctors are General Practitioners, 5 out of 19 doctors are under the age of 40, 2 doctors are both General Practitioners and under the age of 40.
Therefore:
P(General Practitioner) = 6/19
P(Under 40) = 5/19
P(General Practitioner and under 40) = 2/19
Substituting these values into the formula:
P(General Practitioner or under 40) = 6/19 + 5/19 - 2/19
= 9/19
Therefore, the probability of randomly selecting a doctor who is either a General Practitioner or under the age of 40 is 9/19.

The total revenue earned (in dollars) from selling the books is given by the function R = 33.70N.
Let P be the profit made (in dollars). Wnite an equation relating P to N. Simplify your answer as much as possible.
P =
Answer:
The profit made is given by the difference between the total revenue and the total production cost:
P = R - C
Substituting the given expressions for R and C, we get:
P = 33.70N - (750 + 16.95N)
Simplifying:
P = 16.75N - 750
Therefore, the equation relating P to N is P = 16.75N - 750

receives GHc500 increase in commission for each additional house sold. How many houses must
she sell to reach a total commission of GHc6500?
If an Estate dealer sells houses and makes a commission of GHc3750 for the first house sold and receives GHc500 increase in commission for each additional house sold, for reaching a total commission of GHc6500, she must have sold 6.5 houses.
How is the number of houses sold determined?The number of houses the estate dealer sold to reach a total commission of GHc6500 can be determined using the mathematical operations of subtraction, division, and addition.
The total commission received = GHc6,500
The commission for the first house = GHc3,750
The commission for the remaining houses sold = GHc2,750 (GHc6,500 - GHc3,750)
The commission for additional sale of each house = GHc500
The number of additional houses sold = 5.5 (GHc2,750/GHc500)
The total number of houses sold = 6.5 (5.5 + 1 or the first house)

The following is the recursive formula for the arithmetic sequence in this issue:
c(1) = -16.
c(n) = c(n - 1) - 17.
An arithmetic sequence is a series of numbers where each term is obtained by adding a fixed constant, known as the common difference, to the previous term. For example, in the sequence 2, 5, 8, 11, 14, 17, each term is obtained by adding 3 to the previous term.
The formula for finding the nth term of an arithmetic sequence is: a(n) = a(1) + (n-1)d, where a(1) is the first term, d is the common difference, and n is the term number. For example, to find the 10th term of the sequence 2, 5, 8, 11, 14, 17, we would use the formula a(10) = 2 + (10-1)3 = 29. Arithmetic sequences have many practical applications, such as in finance, where they can be used to calculate the interest earned on an investment over time.

assume that 1 laborer produces 6 units of output, 2 laborers produce 15 units of output, 3 laborers produce 25 units of output, and 4 laborers produce 34 units of output. diminishing returns to labor set in when the firm hires the
The marginal product of labor initially increases from 6 to 9, but then starts to decrease as more labor is added. Therefore, the firm experiences diminishing returns to labor when it hires a third laborer.
Diminishing returns to labor occur when the marginal product of labor (i.e., the additional output produced by adding one more unit of labor) decreases as more labor is added. We can calculate the marginal product of labor for each level of labor as follows:
1 laborer: 6 units of output (marginal product = 6)
2 laborers: 9 units of additional output (total output = 15, marginal product = 9)
3 laborers: 10 units of additional output (total output = 25, marginal product = 10)
4 laborers: 9 units of additional output (total output = 34, marginal product = 9)
The law of diminishing marginal returns is a concept from economics that explains how the marginal output of a production process starts to decrease as the input goes up. It is also used to refer to a point at which output increases at a diminishing rate as more units of labor are added to a production process. This can also be called the point of decreasing marginal productivity.

In standard mathematics, what is a polynomial function?A polynomial function is one that involves only non-negative integer powers or positive integer exponents of a variable in an equation such as the quadratic equation, cubic equation, and so on.
In the standard form of a polynomial, the terms are written in descending order of degree. The standard form for a polynomial of degree n is:

We have the polynomial in this case:
9x² - 213
To write it in standard form, rearrange the terms in descending order of degree as follows:
213 + 9x²
As a result, the standard form of the polynomial is:
9x² - 213
This polynomial has degree 2 (because x's highest exponent is 2) and two terms (since there are two distinct parts to the expression, a constant and a term with an x squared coefficient).

False. A mean difference of zero does not necessarily indicate that the peppers are well distributed between the two groups.
What is number?Number is a mathematical object used to count, measure, and label. It is one of the most fundamental concepts in mathematics and is used to describe a wide variety of physical, logical, and abstract objects. Numbers are used to represent quantities, lengths, temperatures, money, and many other measurements. They are also used to represent abstract ideas, such as the number of days in a year or the number of colors in a rainbow.
Although the mean may be equal between the two groups, the distribution of the peppers could be skewed and not evenly distributed. For example, one group could have all large peppers and the other all small peppers and the mean would be equal. This would not be considered well distributed. To ensure the peppers are evenly distributed, one should check the standard deviation or range of the data to see if the peppers are spread across both groups.

If sin(2x) = cos(x), where 0° ≤ x < 180°, then, The possible angle values of x are 90°, 30° and 150°.
The sine and the cosine are trigonometric functions of the angles. The sine and cosine of an acute angle are defined in the context of a right triangle: for a given angle, its sine is the ratio of the length of the side opposite the angle to the length of the longest side of the angle. triangle (the hypotenuse ), and the cosine is the adjacent side The ratio of the length to the hypotenuse.
According to the Question:
Given that,
sin(2x) = cos(x) where 0° ≤ x < 180°
We know that:
sin(2x) = 2 sin(x) cos(x)
⇒ 2 sin(x) cos(x) = cos(x)
Subtract cos(x) on both sides
2 sin(x) cos(x) - cos(x) = 0
cos(x) (2sinx-1)=0
It means, cos(x) = 0 and (2sin x -1 ) = 0
