The range is 5 years.The median is 18 years.

To determine the range and median from the given dot plot of ages, we need to analyze the distribution of the data points.

The range represents the difference between the maximum and minimum values in a dataset. Looking at the dot plot, the minimum age appears to be 16, while the maximum age is 21. Therefore, the range can be calculated as:

Range = Maximum age - Minimum age = 21 - 16 = 5 years.

Thus, the range of the ages of employees at the summer camp is 5 years.

The median represents the middle value in a dataset when it is arranged in ascending or descending order. To determine the median, we need to organize the ages in order from least to greatest:

16, 17, 18, 19, 20, 21

Since there are six data points, the median would be the value in the middle. In this case, the median would be the third value, which is 18.

Therefore, the median of the ages of employees at the summer camp is 18 years.

Answer:

Step-by-step explanation:

You want the quotient and remainder from division of (6x² +27x +17) by (x +4).

Synthetic division of a polynomial by a monic binomial is an easy way to perform the division without a lot of writing. The attachment pretty well describes the process.

The result is a quotient of 6x +3, and a remainder of 5.

__

Additional comment

A "monic" polynomial is one that has a leading coefficient of 1.

The number at upper left in the synthetic division tableau is the zero of the divisor. Using the negative of the divisor constant means we can add partial products, saving the confusion and error associated with subtraction.

The mean of the test is 45.

Let's use the formula for z-score:

z = (x - μ) / σ

where z is the number of standard deviations from the mean, x is the raw score, μ is the mean, and σ is the standard deviation.

For the first score of 30, we know that it falls three standard deviations below the mean:

-3 = (30 - μ) / σ

Simplifying this equation, we get:

-3σ = 30 - μ

μ = 30 + 3σ

For the second score of 60, we know that it falls three standard deviations above the mean:

3 = (60 - μ) / σ

Simplifying this equation, we get:

3σ = 60 - μ

μ = 60 - 3σ

Now we can set these two equations equal to each other, since they both equal μ:

30 + 3σ = 60 - 3σ

6σ = 30

σ = 5

Now we can plug this value of σ back into one of the equations for μ:

μ = 30 + 3σ

μ = 30 + 3(5)

Answer:

The expression πr2h is a monomial because it is a single term that is the product of three variables: π, r2, and h. The term "mono" means "one," and "monomial" refers to a single term in algebraic expressions.

The degree of a monomial is the sum of the exponents of its variables. In this case, the degree of the monomial is 3, because the variables π, r, and h have exponents of 1, 2, and 1 respectively. Therefore, the degree of the monomial is 1 + 2 + 1 = 3.

The probability that exactly 3 of those games were won by the colonies is 25%.

We are given that;

Number of colonies= 4

Number of games= 3

Now,

To find the probability of exactly 3 wins out of 4 games, we can use the binomial probability formula1:

P(X = 3) = nCx * p^x * q^(n-x)

where n is the number of trials (4 games), x is the number of successes (3 wins), p is the probability of success (0.5), q is the probability of failure (1 - p = 0.5), and nCx is the combination of n things taken x at a time.

P(X = 3) = 4C3 * 0.5^3 * 0.5^(4-3) P(X = 3) = (4! / (3! * (4-3)!)) * 0.125 * 0.5 P(X = 3) = (24 / (6 * 1)) * 0.0625 P(X = 3) = 4 * 0.0625 P(X = 3) = 0.25

The average value of f(x) over the interval [-14, 14] is 0.

The average value of the function f(x) = 14 - |x| over the interval [-14, 14] we need to use the formula:

[tex]f_{ave[/tex] = (1/(b-a)) × integral(a to b) f(x) dx

a and b are the limits of integration.

a = -14 and b = 14.

So we have:

[tex]f_{ave[/tex] = (1/(14 - (-14))) × integral(-14 to 14) (14 - |x|) dx

Simplifying the integral get:

[tex]f_{ave[/tex] = (1/28) × integral(-14 to 0) (14 + x) dx + (1/28) × integral(0 to 14) (14 - x) dx

The shopkeeper should have sold the pen for Rs. 13.80 in order to earn a profit of 15%. Option C

To determine the selling price of the pen in order to earn a 15% profit, we can use the concept of a profit margin.

Let's start by finding the cost price of the pen. Since the shopkeeper wants to make a 10% profit when selling the pen for Rs. 13.20, we can set up the equation:

Cost price + 10% profit = Selling price

Let's assume the cost price of the pen is C. Then, we can write theequation as:

C + 0.1C = 13.20

Simplifying the equation, we have:

1.1C = 13.20

Dividing both sides by 1.1, we find:

C = 12

So, the cost price of the pen is Rs. 12.

Now, to determine the selling price that will yield a 15% profit, we can use the formula:

Selling price = Cost price + Profit

Profit is calculated as a percentage of the cost price. In this case, the profit percentage is 15%. Substituting the values, we have:

Selling price = 12 + 15% of 12

Selling price = 12 + (0.15 * 12)

Selling price = 12 + 1.8

Selling price = 13.8

Therefore, the shopkeeper should have sold the pen for Rs. 13.80 in order to earn a profit of 15%.

The correct answer is option c. Rs. 13.80. Option C

C) All the zeroes are,

x = (5 ± √13)/2

Given that;

Function is,

⇒ f (x) = x³ - 3x² - 7x + 6

Now, We can check (x + 2) is a factor of function or not as;

If x + 2 is a factor of function, then x = - 2 is satisfy the function.

So, Put x = - 2;

⇒ f (x) = x³ - 3x² - 7x + 6

⇒ f (- 2) = (- 2)³ - 3 (- 2)² - 7 (- 2) + 6

⇒ f (- 2) = - 8 - 12 + 14 + 6

⇒ f (- 2) = 0

Thus, (x + 2) is a factor of the function,

Hence, We can find all the zeroes as;

(x + 2) ) x³ - 3x² - 7x + 6 (x² - 5x + 3
