The breaking strengths of cables produced by a certain manufacturer have a standard deviation of 92 pounds. A random sample of 90 newly manufactured cables has a mean breaking strength of 1700 pounds. Based on this sample, find a 95% confidence interval for the true mean breaking strength of all cables produced by this manufacturer. Then give its lower limit and upper limit. Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place

Answers

Answer:

To find the 95% confidence interval for the true mean breaking strength of all cables produced by the manufacturer, we can use the formula:

Confidence Interval = Sample Mean ± (Critical Value * Standard Error)

First, let's calculate the standard error, which is the standard deviation divided by the square root of the sample size:

Standard Error = Standard Deviation / √(Sample Size)

= 92 / √(90)

≈ 9.685

Next, we need to determine the critical value corresponding to a 95% confidence level. Since the sample size is large (n > 30), we can use the z-table. The z-value for a 95% confidence level is approximately 1.96.

Now we can calculate the confidence interval:

Confidence Interval = Sample Mean ± (Critical Value * Standard Error)

= 1700 ± (1.96 * 9.685)

Lower Limit = 1700 - (1.96 * 9.685)

≈ 1679.69

Upper Limit = 1700 + (1.96 * 9.685)

≈ 1720.31

Therefore, the 95% confidence interval for the true mean breaking strength of all cables produced by this manufacturer is approximately (1679.7, 1720.3). The lower limit is 1679.7 pounds, and the upper limit is 1720.3 pounds.

d&t / material used for marking out plastic and it's drawing form 1

Answers

In Design and Technology (D&T), when marking out plastic materials, various tools and techniques can be employed depending on the specific requirements and characteristics of the material. The choice of marking tools largely depends on the type of plastic and the desired outcome. Additionally, the drawing form used for marking out plastic typically involves the use of technical drawings or templates to ensure accurate and precise measurements.

Marking Tools:

1. Permanent Marker: A permanent marker with a fine tip is often used to make visible and long-lasting marks on plastic materials. It allows for clear lines and can be easily applied on smooth surfaces.

2. Scriber: A scriber, which is a sharp-pointed tool, can be used to scratch or score lines onto the plastic surface. This method is particularly useful for creating precise guidelines or marking out intricate shapes.

3. Masking Tape: Masking tape can be used to create temporary markings on plastic surfaces. It provides a clear boundary for cutting or shaping operations and can be easily removed without leaving residue.

4. Stencil: Stencils are pre-designed templates with cut-out shapes or patterns. They can be used to transfer specific designs or markings onto the plastic surface accurately.

Drawing Form:

1. Technical Drawings: Technical drawings, such as orthographic projections or isometric views, are commonly used in D&T to represent the shape, dimensions, and features of a plastic component. These drawings provide precise measurements, angles, and details necessary for accurate marking out.

2. Templates: Templates are pre-made patterns or outlines that are used as guides for marking out specific shapes or profiles onto the plastic material. Templates ensure consistency and accuracy in replicating complex shapes or designs.

identify various limiting factors (abiotic and biotic) in an ecosystem

Answers

Answer:

Explanation:

In ecology, biotic and abiotic factors make up an ecosystem. Biotic factors are the living parts of the ecosystem, such as plants, animals, and bacteria. Abiotic factors are the nonliving parts of the environment, such as air, minerals, temperature, and sunlight. Organisms require both biotic and abiotic factors to survive. Also, a deficit or abundance of either component can limit other factors and influence an organism's survival. The nitrogen, phosphorus, water, and carbon cycles have both biotic and abiotic components.

Answer:

Biotic factors are living things within an ecosystem; such as plants, animals, and bacteria, while abiotic are non-living components; such as water, soil and atmosphere. The way these components interact is critical in an ecosystem. Thus, organisms tend to compete for their limited availability in the ecosystem. Different limiting factors affect the ecosystem. They are (1) keystone species, (2) predators, (3) energy, (4) available space, and (5) food supply. Some examples of limiting factors are biotic, like food, mates, and competition with other organisms for resources. Others are abiotic, like space, temperature, altitude, and amount of sunlight available in an environment. Limiting factors are usually expressed as a lack of a particular resource.

A percentage of the loan that is charged to cover the cost of giving the loan is known as an origination fee. The correct option is b.

What is the origination fee?

The origination fee is the fee that is given to the lender when taking a loan. The lender sets the loan and in exchange for borrowing loans, the lender gets paid by the borrowers.

The origination fee is about 1% to 0.5% of the amount of the loan. The origination fee itself can cover a variety of things, some of which may be broken out in your Loan Estimate.

If a person does not have money to pay the lender of the loan application, then there are two ways from which the loan can be paid. These ways the fee may be deducted from the funds you receive or rolled into the balance of your loan.

Write a narrative on falling asleep on your way home and getting lost make sure to include what happened and how you eventually got home.

As I got into my car after a long day at work, I felt the exhaustion hit me like a ton of bricks. The drive home was only supposed to take 20 minutes, but my heavy eyelids made the trip feel like an eternity. I tried my best to keep my focus on the road, but it was a losing battle.

I remember struggling to keep my eyes open, and then everything went black. When I opened my eyes again, I was no longer on the familiar streets of my neighborhood. Panic set in as I realized I had fallen asleep at the wheel and must have taken a wrong turn.

My phone's battery was dead, and I had no idea where I was or how to get back home. I drove around aimlessly, hoping to recognize a street name or landmark, but everything looked unfamiliar.

After what seemed like hours, I stumbled upon a gas station and asked for directions. The attendant gave me a puzzled look, probably wondering how I got so lost, but kindly guided me back on track.

Finally, I saw the familiar streets and landmarks, and the relief that washed over me was indescribable. I made it home, safe and sound, but shaken by the experience.

From that day on, I vowed to never drive when overly tired and to always have a fully charged phone for emergencies. It was a wake-up call that reminded me of the importance of road safety and being alert behind the wheel.

Given

\(4^{\frac{1}{2} }*\frac{2}{\sqrt[4]{16} } -10\div 2\)

Lets evaluate the given expression.

Remember to use PEMDAS.

In the second term, rewrite \(16\) as \(2^4\).

\(4^{\frac{1}{2} }*\frac{2}{\sqrt[4]{2^4} } -10\div 2\)

Pull terms out from under the radical, assuming positive real numbers, then simplify.

\(4^{\frac{1}{2}} *\frac{2}{2} -10\div 2\\4^{\frac{1}{2}} *1-10\div 2\\4^{\frac{1}{2}}-10\div 2\)

Rewrite \(4\) as \(2^2\).

\((2^2)^{\frac{1}{2}} *\frac{2}{2} -10\div 2\)

We can use the power rule to multiply exponents.

The power rule is

\((a^b)^c=a^b^c\)

\(2^{2\left(\frac{1}{2}\right) } *\frac{2}{2} -10\div 2\)

Cancel the common factor of 2.

\(2^1*\frac{2}{2} -10\div 2\)

Any number to the power of 1 stays the same.

\(2*\frac{2}{2} -10\div 2\)

\(\frac{2}{2}\) is equal to \(1\)

\(2*1 -10\div 2\)

Any number multiplied by 1 stays the same.
