Answer:

part 1: After one year, the cost of the refrigerator modeled by f(x) is cheaper.

part 2: 14 years

part 3: g(x)

part 4: 51

hope this helps :)

To find the cheapest refrigerator in the long run, calculate the limit of the cost per year as x approaches infinity for both given functions and compare the results. The cost of the refrigerator modeled by f(x) will be the cheapest, averaging $62 per year.

The average annual costs for owning two different refrigerators for x years can be calculated using the given functions: f(x) = 850 + (62x / x) and g(x) = 1004 + (51x / x). To determine which refrigerator will be cheaper in the long run, we need to find the limit of the cost per year as x approaches infinity for both functions. Taking the limit as x approaches infinity for f(x), we get 62. Therefore, the cost of the refrigerator modeled by f(x) will be the cheapest, averaging $62 per year.

Answer:

For the Critical Reading part: P = 0.6578

For the Math part: P = 0.6578

Step-by-step explanation:

See attached photo for solutions

The probability that a sample of 90 test takers will provide a sample mean test score within 10 points of the population means of 502 (Critical Reading) and 515 (Mathematics) on the SAT is approximately 68.26% for both.

To calculate the probability for each section of the SAT, we use the formula for the z score: z = (X - μ) / (σ / sqrt(n)). In this case, X is the sample mean, μ is the population mean, σ is the population standard deviation, and n is the sample size.

For the Critical Reading section, μ = 502, X is between 492 and 512 (502 ±10), σ = 100, and n = 90. When we input these values into the formula, we get a z value of -1 (for 492) and 1 (for 512) approximately. We then use a z-table to find the probability associated with these z-values. The probability for z = -1 is 0.1587 and for z = 1 is 0.8413. To find the probability that the sample mean lies within these z values, we subtract the lower probability from the higher one, which gives us 0.6826 or 68.26%.

The same steps are applied to the Mathematics section where μ = 515. The resulting probability also comes to around 68.26% that a sample mean test score will be within 10 points of the population mean.

Answer:

The rectangular 5 x 10 table.

Step-by-step explanation:

To find which table the office manager needs to get so he can sit more people at it is decided by one factor, the perimeter. The rectangular one, which is 5 x 10 the perimeter is (5 x 2) + (10 x 2) = 10 + 20 = 30. The circular one can be calculated by the equation[tex]\pi * d[/tex] where d = 8. Putting [tex]/pi[/tex] x 8 in my calculator and it comes out approximately at 25.132, having a less amount of perimeter space to work with, making the rectangular table the way to go.

The rectangular and circular tables offer roughly the same area, approximately 50 square feet. However, due to space utilization, traditionally, rectangular tables can seat more people as it allows seating around the sides and ends instead of wasting some space at the edges, a common issue with circular tables.

Determining which table can seat more depends on how much space each person needs. However, as a basic comparison, we can calculate the area of each table as a starting point.

The rectangular table is 5 feet wide and 10 feet long. Therefore, its area is 5 * 10 = 50 square feet.

For the circular table, we can use the formula for the area of a circle, which is pi * r^2, where r is the radius. The radius is half the diameter, so it is 4 feet here. Thus, the area is about 3.14 * 4^2 = 50.24 square feet.

Both tables have very similar areas. However, people can sit around both the sides and ends of a rectangular table, while some space might be wasted around the edges of the circular one. Therefore, the office manager might find that the rectangular table can seat more people comfortably.

Answer:

128 m²

Step-by-step explanation:

The area of the rhombus can be calculated using the diagonals

area = [tex]\frac{1}{2}[/tex] diagonal × diagonal

       = [tex]\frac{1}{2}[/tex] × 16 × 16 = 8 × 16 = 128 m²

Final answer:

The area of a rhombus can be found using the formula (diagonal1 * diagonal2) / 2.

Explanation:

To find the area of a rhombus, you can use the formula:

Area = (diagonal1 * diagonal2) / 2

Where diagonal1 and diagonal2 are the lengths of the diagonals of the rhombus.

For example, if one diagonal is 8 meters and the other diagonal is 6 meters, the area would be:

Area = (8 * 6) / 2 = 24 square meters

Since this is subtraction, everything must be turned negative in the second polynomial.

(6x^2 - 5x) - (2x^2 + 3x - 2)

6x^2 - 5x - 2x^2 - 3x - (-2)

6x^2 - 5x - 2x^2 - 3x + 2

Now, reorder the terms to make it easier.

6x^2 - 2x^2 - 5x - 3x + 2

Now, just combine like terms.

4x^2 - 5x - 3x + 2

4x^2 - 8x + 2

There’s the answer!

Answer: 2500 years

Step-by-step explanation:

I'm not quite sure if I'm doing this right myself but I'll give it a shot.

We use this formula to find half-life but we can just plug in the numbers we know to find t.

[tex]A(t)=A_{0}(1/2)^t^/^h[/tex]

We know half-life is 5730 years and that the parchment has retained 74% of its Carbon-14. For [tex]A_{0[/tex] let's just assume that there are 100 original  atoms of Carbon-14 and for A(t) let's assume there are 74 Carbon-14 atoms AFTER the amount of time has passed. That way, 74% of the C-14 still remains as 74/100 is 74%. Not quite sure how to explain it but I hope you get it. h is the last variable we need to know and it's just the half-life, which has been given to us already, 5730 years, so now we have this.

[tex]74=100(1/2)^t^/^5^7^3^0[/tex]

Now, solve. First, divide by 100.

[tex]0.74=(0.5)^t^/^5^7^3^0[/tex]

Take the log of everything

[tex]log(0.74)=\frac{t}{5730} log(0.5)[/tex]

Divide the entire equation by log (0.5) and multiply the entire equation by 5730 to isolate the t and get

[tex]5730\frac{log(0.74)}{log(0.5)} =t[/tex]

Use your calculator to solve that giant mess for t and you'll get that t is roughly 2489.128182 years. Round that to the nearest hundred years, and you'll find the hopefully correct answer is 2500 years.

Really hope that all the equations that I wrote came out good and that that's right, this is definitely the longest answer I've ever written.

Answer:

40

Step-by-step explanation:

You do 480 divided by 12

To find the length of the room Alyssa wants to tile, given its area is 480 square feet and its width is 12 feet, divide the area by the width. The length is found to be 40 feet.

The question asks to find the length of a room given its area is 480 square feet and its width is 12 feet. To find the length, you use the formula for the area of a rectangle, which is Area = Length × Width. Since we're given the area and the width, we can rearrange the formula to solve for the length by dividing the area by the width.

Therefore, Length = Area / Width = 480 sq ft / 12 ft = 40 feet.

This means that the length of the room Alyssa wants to tile is 40 feet.

They want only the exponential equation, here's the point.

Equation

[tex]\text{Amount the pressure becomes} = \dfrac{101 kpa}{(1+\dfrac{ 1.8}{100} )^\frac{h}{500} }[/tex]

What this gives you is the equation for a rise every  500 feet. To figure out the %

Use

[tex]\text {\% =} \frac{\text{101 - answer from above equation}}{101}*100\%[/tex]

Example

Let h = 1000 feet

101 / (1 + 1.8/100) ^ (1000/500)

101 / (1.018)^2

101 / 1.036324

97.46

Now take this number and use the second formula

% = (101 - 97.46)/101 * 100%

% = 3.54%

The answer should be 3.6% (2 * 1.8%)

This is close enough. The question does say approximately.

1500 feet will give you 5.2% which is close to 5.4 (1.8 * 3). The higher you go, the more it is going to be out, but the results will always be close.

The volume of a rectangular box is calculated by multiplying its dimensions. Timmy's box has a volume of 24 cubic inches. Paul's box, with dimensions three times larger, has a volume of 5832 cubic inches which is 5808 cubic inches more than Timmy's.

The volume of a rectangular box is found by multiplying its length, width, and height. In Timmy's case, the volume is 3" * 4" * 2" which equals to 24 cubic inches. Paul's box has dimensions that are three times larger, which means the volume is (3 * 3") * (3 * 4") * (3 * 2")  = 27 * 36 *6 = 5832 cubic inches. The difference in volume is 5832 - 24 which equals to 5808 cubic inches, so Paul's box has 5808 cubic inches more volume than Timmy's.

The normal distribution describes how the values of a variable are distributed. Given a mean of 15 and standard deviation of 5.95, the area within which values lie could be found using the properties of a normal distribution, which state that ~68% of data falls within one standard deviation of the mean, ~95% within two standard deviations, and ~99.7% within three standard deviations.

This question is related to the normal distribution in statistics. The normal distribution is a probability function that describes how the values of a variable are distributed. It is a symmetric distribution where most of the observations cluster around the central peak and the probabilities for values further away from the mean taper off equally in both directions. Extreme values in both tails of the distribution are similarly unlikely.

Given a normal distribution with a mean of 15 and a standard deviation of 5.95, we are asked to find the area within which the values lie. Using the properties of a normal distribution, we know that:

So, if we wanted to find the area within one standard deviation of the mean, for instance, we would calculate the values of (mean - standard deviation) and (mean + standard deviation), which would represent the range within which approximately 68% of the data lies.
