A lab found that 670 rats could run through a maze in a mean time of 4.7 seconds. What is the 99% confidence interval for the population mean? Use the formula for margin of error: z•σ/√n. Please explain each step, particularly how to find the population standard deviation.

Answers

Using the formula for margin of error as

MOE = z * σ / √n

would be very difficult since we are not given the value of the standard deviation. Standard deviation value must be given since it is obtained from the experiment.

However, we use another formula for MOE in the form of:

MOE = z sqrt [p (1 – p) / n]

where p is the proportion at 99% confidence interval at z crit value. From the standard distribution tables, this corresponds to a p value of:

z crit = 2.58

p = 0.9951

Therefore the margin of error is:

MOE = 2.58 sqrt [0.9951 (1 – 0.9951) / 670]

MOE = 6.96 x 10^-3 = 0.00696 s

We can see that at 99% Confidence interval, the Margin of Error is extremely small (almost 0). For the sake of calculation:

Confidence interval = 4.7 s ± 0.00696 s

Confidence interval = 4.69304, 4.70696

Is it correct to say that a cube with side lengths 6cm have the same volume and surface area?

Answers

Yes it is correct. The surface area requires that you take the area of all the lateral faces, of which there are 6, and add them all together, giving you 216. The volume then requires that you take the length times the width times the height which is also 216. So odd, but yes, they are the same.

An electrical heating element produces heat depending on the resistance of the element and the current passed through it. The heat produced can be given by the formula h = I2R where h is the heat generated, I is the current, and R is the resistance. If the element has a fixed current of 2 amps passing through it and a variable current of x amps, it is able to produce a heat of 10x3 + 80, depending on the variable resistance for different additional values of current x. Determine the formula for the variable resistance.

Answers

The heat produced by current I is
H = I²R
where
R = resistance.
According to the formula, heat produced is proportional to the square of the current.

When a current of I = 2 amps is applied, the heat produced is
H = 10x³ + 80.
This heat includes heat due to a fixed current of 2 amps, and heat due to a variable current of x amps.

Because the heat produced is proportional to the square of the current, write the expressions as
H = (10x)*(x²) + 20*(2²)

The second term on the right is heat due to the fixed current of 2 amps, written as
20*(2²).
Therefore the fixed resistance is R = 20 ohms, and the square of the fixed current is 2².

The first term represents heat due to variable resistance, written as
(10x)*(x²).
Therefore the variable resistance is 10x, and the square of the variable current is x².

Answer:
The variable current is 10x.

Answer:

(10x - 40) + 120 / (x+2)

When dividing with polynomials, the goal is to determine how many times the dividend divides evenly into the?

Answers

Whether dividing constant terms or polynomials, we always have definitive terms when it comes to division. Suppose we say, 10x divided by 2. The dividend is the 10x and the divisor is the 2. In other words, the dividend is the number to be divided by the divisor, to obtain the answer called the quotient.

When dividing polynomials, your main goal is to be able to divide the dividend evenly into the divisor. For example, we divide x²+2x+1 by x+1. The first thing you're going to focus is, what term will completely divide the first term of the polynomial? That would be x. Why? Because when you multiply x with x+1, the product is x²+x. When you subtract this from the polynomial, the x² will cancel out. All you have to do is subtract x from 2x, yielding x. Then, you carry down the last term of the equation: +1. You do the steps again. The term that will completely divide x+1 by x+1 is 1. When you subtract the two, you will come up with zero. That means there is no remainder. The polynomial is divisible by the divisor.
x + 1

The bear population increases at a rated of 2% each year. There are 1573 bears this year. What is the growth factor, b?

Answers

that would be 1 + 0.02

Growth factor = 1.02.

Final answer:

To find the growth factor, b, we can use the formula for exponential growth: n = ln(M)/ln(b), where n is the number of years, M is the final population, and b is the growth factor.

Explanation:

To find the growth factor, b, we can use the formula for exponential growth: n = ln(M)/ln(b), where n is the number of years, M is the final population, and b is the growth factor. In this case, the final population is 1573 bears. Let's solve for b: n = ln(1573)/ln(b). To isolate b, we can take the exponential of both sides: b^n = 1573. Now we can solve for b by taking the nth root of 1573. The growth factor, b, is the value that, when raised to the power of the number of years, gives us the final population of bears.

Use calculus to find the largest possible area for a rectangular field that can be enclosed with a fence that is 400 meters long.

Answers

the largest rectangular area is actually a square.

so the side would be 400/4 = 100 feet

area of a square is S^2

100^2 = 10,000 square feet

Maximum area is 5625m² when the dimensions are 75m × 75m.

To maximize the area of the rectangular field enclosed by a 300-meter-long fence, let's denote the length of one side as x meters and the other side as y meters.

Since the fence length is 300 meters, the perimeter of the rectangle is 2x + 2y = 300, or x + y = 150.

We want to maximize the area, which is given by A = xy.

To find the maximum, we'll use the constraint equation to express one variable in terms of the other, then substitute into the area formula.

1. From the constraint equation, x = 150 - y.

2. Substitute x into the area formula: A = (150 - y)y.

3. Take the derivative of A with respect to y and set it to zero to find the critical points.

4. Solve for y to find the value that maximizes A.

5. Use this value of y to find the corresponding x.

6. Calculate the maximum area using A = xy.

If your front lawn is 24.0 feet wide and 20.0 feet long, and each square foot of lawn accumulates 1050 new snow flakes every minute, how much snow (in kilograms) accumulates on your lawn per hour? assume an average snow flake has a mass of 1.70 mg.

Answers

First find the area of the front lawn:
Area = length * width
Area = 24.0ft * 20.0ft
Area = 480ft^2

Next, find the weight in kilograms of the snow per square foot per hour per ft^2:
[tex]weight\ per\ ft^{2}=\frac{1050\ snowflakes}{minute}\\\\weight\ per\ ft^{2}=\frac{1050\ snowflakes}{minute}*\frac{1.70\ milligrams}{snowflake}*\frac{1\gram}{1000\milligrams}*\frac{1\kilogram}{1000\grams}* \frac{60\minutes}{1\hour}\\\\weight\ per\ ft^{2}=\frac{1050*1.70}{1000*1000*60}*\frac{kg}{hour}=2.975*10^{-5}\ \frac{kg}{hour}\\\\weight=2.975*10^{-5}\ \frac{kg}{hour*ft^{2}}[/tex]

Now multiply the area of the lawn by the weight of the snow per hour per ft^2:
[tex]weight\ of\ snow=lawn\ area*weight\ per\ hour\ per ft^{2}\\\\weight=480\ ft^{2}*2.975*10^{-5}\ \frac{kg}{hour*ft^{2}}\\\\weight=0.01428\ \frac{kg}{hour}[/tex]

Thus your answer is .01428 kg.

Complete the solution of the equation. find the value of y when x equals 11 8x+6y=28

Answers

If x is 11, then we replace x with 11 in the equation.
8(11) + 6y = 28
88 + 6y = 28
We will subtract 88 from both sides to get rid of the constant.
6y = -60
To isolate the variable, we will divide both sides by 6.
y = -10
In this equation, y equals -10.

First, substitute the value of x back into the equation.

8x + 6y = 28 becomes 8(11) + 6y = 28

Now solve for y.

8(11) + 6y = 28
88 + 6y = 28
6y = -60 <-- Subtract 88 from each side
y = -10 <-- Divide both sides by 6

So, y is equal to -10.

A car travels 2/5 mile in 1/2 minute. what is the cars speed in miles per hour?

Answers

So a car travels 2/5 mile in 1/2 minute. This means a car travels 4/5 mile in one minute. Then multiply by 60 to find how many miles it travels in 60 minutes, and you can see that you have 240/5, which is equal to 48. Therefore the speed of the car in miles per hour is 48 miles an hour. Hope this helps. Feel free to ask more questions, and ask questions about my explanation.

Final answer:

The speed of the car is 48 miles per hour, based on the given information that the car travels 2/5 miles in 1/2 minute.

Explanation:

To solve this problem, we first need to recognize that the car has traveled 2/5 miles in 1/2 minute. To calculate the speed in miles per hour (mph), we need to find how far the car would go in 1 hour. In other words, how many 1/2 minutes are there in an hour? An hour has 60 minutes, so there are 2*60=120 half-minutes in an hour. If the car travels 2/5 mile in each half minute, then in one hour (or 120 half-minutes), the car would travel 2/5*120=48 miles. Consequently, the car's speed is 48 miles per hour.

4 - 7 = -3

Now, we square the -3.

-3^2 =
-3 * -3 = 9
