To estimate the average height of black spruce trees in a 1,000 ha plot with 99% confidence that the estimate is within 0.5 m, you need a sample size of at least 19. This is based on the standard deviation of tree heights in a nearby location of 1.10 m as determined in a study conducted last year.

To estimate the average height of black spruce trees in a 1,000 ha plot with 99% confidence that the estimate is within 0.5 m, we can use the formula for sample size calculation:

n = (z² × σ²) / E²

Where:

n = sample size

z = z-score for the desired confidence level (99% confidence level corresponds to a z-score of 2.576)

σ = standard deviation (1.10 m)

E = margin of error (0.5 m)

Plugging in the values into the formula, we get:

n = (2.576² × 1.10²) / 0.5²n = 18.15.

Therefore, the sample size must be at least 19 black spruce trees to have 99% confidence that the estimate is within 0.5 m.

Answer:

The formula for the length of an arc of a circle is given by:

length of arc = (central angle/360) x 2πr

where r is the radius of the circle and the central angle is measured in degrees.

In this problem, we know the length of arc RV is 3π/2 units and the radius of circle M is 6 units. Therefore, we can solve for the central angle using the formula above:

3π/2 = (central angle/360) x 2π(6)

3π/2 = (central angle/180) x π x 6

3/2 = (central angle/180) x 6

central angle = (3/2) x (180/6) = 45 degrees

So the approximate measure of angle RMV is 45 degrees, which corresponds to option B.

The average rate of change for the week is calculated by subtracting the first day's attendance (1,534) from the last day's attendance (2,394) and then dividing by the number of days (7).

Number is an abstract concept used to describe a quantity or amount of something. It is used to measure, count, and label objects, people, places, and other things. Numbers can be used to describe size, shape, location, and many other concepts. They are also used to represent data, money, and other mathematical operations. Numbers are the cornerstone of mathematics, and they are used in a variety of ways in everyday life.

This yields an average rate of change of +77.71 people per day.

This average rate of change is only a good measure for how the number of people changed throughout the week if the number of people changed in a consistent manner. If the attendance was relatively stable from day to day, then the average rate of change would accurately reflect the number of people who attended. However, if the attendance changed drastically from day to day, the average rate of change would not accurately reflect the attendance for the entire week.

The rectangle has a length of y + 2xy + x meters and a width of (y + 7x) / (2y + x) meters.

What is a formula of area of rectangle?

Formula for rectangle's area

When calculating a rectangle's area, we multiply the length by the width of the rectangle.

The area of a rectangle is given by the formula:

A = L × W

where A is the area, L is the length, and W is the width.

In this case, we are given that the area is:

[tex]A = y^2 + 8xy + 7x^2[/tex]

and the length is:

L = y + xy + xy + x = y + 2xy + x

To find the width, we can rearrange the formula for the area:

W = A/L

Substituting the given values, we get:

[tex]W = (y^2 + 8xy + 7x^2)/(y + 2xy + x)[/tex]

Now, we can simplify this expression by factoring the numerator:

W = [(y + 7x)(y + x)] / [(y + x)(2y + x)]

Canceling out the common factor of (y + x), we get:

W = (y + 7x) / (2y + x)

Therefore, the width of the rectangle is:

W = (y + 7x) / (2y + x)

So the rectangle has a length of y + 2xy + x meters and a width of (y + 7x) / (2y + x) meters.

Answer:

x= 3 or x = -3

Step-by-step explanation:

We can see here that the two values that x can have if 5x² + 41 = 86 is -3 and +3.

To find the values of x that satisfy the equation 5x² + 41 = 86, we can start by isolating the term with the variable on one side of the equation. Here's the step-by-step solution:

Subtract 41 from both sides of the equation:

5x² + 41 - 41 = 86 - 41

5x² = 45

Divide both sides of the equation by 5:

(5x²) / 5 = 45 / 5

x² = 9

Take the square root of both sides of the equation:

√(x²) = √9

x = ±3

Therefore, the equation 5x² + 41 = 86 has two solutions: x = 3 and x = -3.

The exact form of the zeros of the polynomial function c(x)=3x^(4)-2x^(3)-39x^(2)-10x+24 are x=-4, x=-3/2, x=2, and x=1.

To find all the zeros of the polynomial function c(x)=3x^(4)-2x^(3)-39x^(2)-10x+24, we need to find the values of x that make c(x)=0. One way to do this is by using the Rational Root Theorem, which states that if a polynomial has rational zeros, then they must be in the form of p/q, where p is a factor of the constant term and q is a factor of the leading coefficient.

The factors of the constant term, 24, are ±1, ±2, ±3, ±4, ±6, ±8, ±12, and ±24. The factors of the leading coefficient, 3, are ±1 and ±3. Therefore, the possible rational zeros are ±1, ±2, ±3, ±4, ±6, ±8, ±12, and ±24.

Using synthetic division, we can test these possible zeros to see if they are actually zeros of the polynomial. After testing, we find that the zeros are -4, -3/2, 2, and 1.

So, the exact form of the zeros of the polynomial function c(x)=3x^(4)-2x^(3)-39x^(2)-10x+24 are x=-4, x=-3/2, x=2, and x=1.

The polynomial function P(x) with a quadratic function zero of 3-4i and an additional zero is P(x) = (x2 - 6x + 25)(x - additional zero).

A polynomial function, P(x), is a function that can be written in the form P(x) = anxn + an-1xn-1 + ... + a1x + a0, where n is a non-negative integer and an, an-1, ..., a1, a0 are real numbers. A quadratic function is a polynomial function of degree 2, which means it can be written in the form P(x) = ax2 + bx + c.

If a polynomial function has a zero of 3-4i, then it must also have a zero of 3+4i, since complex zeros always come in conjugate pairs. This means that the polynomial function must have factors of (x - (3-4i)) and (x - (3+4i)). Multiplying these two factors together gives us (x - 3 + 4i)(x - 3 - 4i) = x2 - 6x + 25.

If the polynomial function also has an additional zero, then it must have a factor of (x - additional zero). Multiplying this factor with the previous one gives us P(x) = (x2 - 6x + 25)(x - additional zero).

So, the polynomial function P(x) with a quadratic function zero of 3-4i and an additional zero is P(x) = (x2 - 6x + 25)(x - additional zero).

The average speed of the boat relative to the water is approximately 17.08 mph.

The average speed of the boat relative to the water can be found by using the formula for distance, speed, and time:

distance = speed × time

We can use this formula to set up two equations, one for the downstream trip and one for the upstream trip:

38 = (s + 6) × t₁

38 = (s - 6) × t₂

We can then use the given information about the total time of the trip to find the values of t₁ and t₂:

4.75 = t₁ + t₂

We can rearrange the first two equations to solve for t₁ and t₂ in terms of s:

t1 = 38/(s + 6)

t2 = 38/(s - 6)

Substituting these values into the third equation and simplifying gives us:

4.75 = 38/(s + 6) + 38/(s - 6)

4.75s² - 57s - 114 = 0

Using the quadratic formula, we can solve for s:

s = (57 ± √(57₂ - 4(4.75)(-114)))/(2(4.75))

s ≈ 17.08 or s ≈ -3.01

Since the speed of the boat cannot be negative, t

Answer: The function to express the total amount of money Martin will make as a function of the number of calls he makes is:

Total Money = (Number of hours worked x Base pay per hour) + (Bonus pay per hour x Number of bonus calls)

Where:

Number of hours worked = 4

Base pay per hour = $75 / 4 = $18.75 (since he works for 4 hours every day and receives $75)

Bonus pay per hour = ($5.50 x (Number of bonus calls)) / 4 (since he works for 4 hours every day and receives a bonus of $5.50 per call over 35 in one hour, which is equivalent to $5.50 / 4 per call)

Number of bonus calls = (Total calls - (Number of hours worked x Baseline calls per hour))

Using this formula, we can calculate how much money Martin will make for the day if he makes a total of 45 calls every hour:

Number of bonus calls = (45 - (4 x 35)) = 5

Bonus pay per hour = ($5.50 x 5) / 4 = $6.875

Total Money = (4 x $18.75) + (4 x $6.875) = $75 + $27.50 = $102.50

Therefore, if Martin makes a total of 45 calls every hour, he will make $102.50 for the day.
