what is the solution to the equipment 3x+2(x-9)= 8x +x -14

Answers

Answer 1

3x + 2(x - 9) = 8x + x - 14

Simplify.

3x + 2x - 18 = 8x + x - 14

Add like terms.

5x - 18 = 9x - 14

Now, we need to add 18 to both sides, and then subtract 9x from both sides so that all variables are on the left side of the equation, and all other numbers are on the right.

5x - 9x = -14 + 18

Simplify.

-4x = 4

Divide both sides by -4.

x = -1

A sample of size 40 is taken from an infinite population whose mean and standard deviation are 68 and 12 respectively. the probability that the sample mean is larger than 70 equals:

Answers

To solve this problem, we can use the z statistic to find for the probability. The formula for z score is:

z = (x – u) / s

Where,

u = the sample mean = 68

s = standard deviation of the samples = 12

x = sample value = 70

In this case, what is asked is the probability that the sample mean is larger than 70, therefore this corresponds to the right of z on the graph of normal distribution.

z = (70 – 68) / 12

z = 2 / 12

z = 0.17

Therefore finding for P at z ≥ 0.17 using the standard distribution tables:

P (z = 0.17) = 0.5675

But this is not the answer yet since this is the P to the left of z. Therefore the correct one is:

P (z ≥ 0.17) = 1 - 0.5675

P (z ≥ 0.17) = 0.4325 = 43.25%

The probability that the sample mean is larger than 70 is 43.25%

The probability that the sample mean is larger than 70 for a sample size of 40 from a population with a mean of 68 and standard deviation of 12 is approximately 14.69%.

To determine this probability, we can use the Central Limit Theorem (CLT), which states that the distribution of sample means will be approximately normal if the sample size is large enough (n ≥ 30 is a common benchmark).

The standard error of the mean is calculated using the formula:

SE = σ / √n

Where σ is the population standard deviation and n is the sample size.

In this case:
σ = 12
n = 40

Therefore,

SE = 12 / √40 ≈ 1.8974

The z-score is calculated using the formula:

z = (M - μ) / SE

Where M is the sample mean,
μ is the population mean,
SE is the standard error.

Given,
μ = 68
M = 70

Therefore,

z = (70 - 68) / 1.8974 ≈ 1.054

Using the z-table, we find the probability that a z-score is less than 1.054 is approximately 0.8531.

However, we need the probability that the sample mean is greater than 70, so we subtract this from 1,

1 - 0.8531 ≈ 0.1469

Thus, the probability that the sample mean is larger than 70 is approximately 0.1469, or 14.69%.

d = the common difference.

The common difference may be determined as
d = a₂ - a₁

The common difference is the difference between successive terms, therefore
d = a₃ - a₂ = a₄ - a₃, and so on..

The sum of the first n terms is
[tex]S_{n}= \frac{n}{2} (a_{1}+a_{n})[/tex]

What is the next number in the sequence 5 10 3 15 20 13 25 30?

Answers

We are asked to determine the next numbers in the given sequence such as 5 10 3 15 20 13 25 30. In order for us to answer this problem, we need to find the difference between the two consecutive number and perform subtraction such as shown below:
For 5 and 10, the difference is -5
For 10 and 3, the difference is 7
For 3 and 15, the difference is -12
For 15 and 20, the difference is -5
For 20 and 13, the difference is 7
For 13 and 25, the difference is -12
For 25 and 30, the difference is -5

Now, we can identify the next two numbers in the sequence since we already know that the format of the difference is -5, 7 and -12. So the next numbers are the following:
30 - 7 = 23
23- (-12) = 35

Therefore, the sequence is 5 10 3 15 20 13 25 30 23 35

In two or more complete sentences describe how to determine the appropriate model for the set of data, (0,2), (2,3), (5,4), (10,5).

Answers

When you have a set of data points and you want to get a model out of it, you do data fitting. The first thing to do is plot the points using a scatter plot type of chart as shown in the picture. I used MS Excel as a tool for data fitting. On the left side of the picture, I used linear fitting. Then, it gives you the linear equation y=0.2907x + 2.2643. It has a correlation coefficient, R^2, of 0.9595. This measures how good your data fits the model equation. The closer it is to 1, the better. However, it is rare to get 1 because that is very ideal. A R^2 of 0.9595 is very satisfactory already. But if you want an even better model, the right side of the picture shows data fitting on a quadratic equation with an equation of y=0.0209x^2 +0.506x+2.0232 with R^2 of 0.9992.

Answer:

The closer this value is to 1 or -1, the better the fit. For linear, the correlation coefficient R2=.96. For quadratic, the R2=.99. For exponential, the R2=.91. This means quadratic is the best fit, very good actually since .99 is very close to 1.

~Ash

Final answer:

To convert 350 square centimeters to square meters, divide by the conversion factor that 1 square meter equals 10,000 square centimeters, resulting in 0.035 square meters.

Explanation:

To convert 350 square centimeters to square meters, we should remember that 1 square meter is equal to 10,000 square centimeters because 1 meter is equal to 100 centimeters and for area, we need to square that conversion (100 cm × 100 cm).

We start with the given quantity of 350 square centimeters. Then, we use the conversion factor 1 square meter is 10,000 square centimeters to perform the calculation, which gives us:

350 cm² × (1 m² / 10,000 cm²) = 0.035 m².

Therefore, 350 square centimeters is equal to 0.035 square meters.

In science class, Savannah measures the temperature of a liquid to be 50∘ Celsius. Her teacher wants her to convert the temperature to degrees Fahrenheit. What is the temperature of Savannah's liquid to the nearest degree Fahrenheit

Answers

Final answer:

To convert the temperature of Savannah's liquid from Celsius to Fahrenheit, use the equation °F = (°C × 9/5) + 32. Savannah's temperature in Celsius is 50°, so her temperature in Fahrenheit is 122°F.

Explanation:

To convert the temperature from Celsius to Fahrenheit, you can use the equation:
°F = (°C × 9/5) + 32.
In this case, Savannah's temperature in Celsius is 50°. Using the equation, we can calculate her temperature in Fahrenheit as:
°F = (50 × 9/5) + 32 = 122°F.
Therefore, the temperature of Savannah's liquid to the nearest degree Fahrenheit is 122°F.

Final answer:

Savannah's liquid, initially measured at 50°C, converts to 122°F using the formula F = C x (9/5) + 32.

Explanation:Converting Celsius to Fahrenheit

To convert the temperature from degrees Celsius to degrees Fahrenheit, we use the conversion formula: F = $ C \times \frac{9}{5} + 32 $, where F is the temperature in degrees Fahrenheit and C is the temperature in degrees Celsius.

In Savannah's case, she measured the temperature as 50°C. Applying the conversion formula:

First, multiply the Celsius temperature by $ \frac{9}{5} $50 \times \frac{9}{5} = 90Then, add 32 to this result to find the Fahrenheit temperature.90 + 32 = 122

Therefore, the temperature of Savannah's liquid to the nearest degree Fahrenheit is 122°F.

How many cubic feet of space is there in a warehouse that is 610 feet wide by 140 feet deep and has an 18 foot ceiling?

Answers

To solve:
Find the volume by multiplying the length, width, and height together.

(610)(140)(18)=1537200

Answer: 1,537,200 ft^3

Final answer:

The warehouse has a volume of 252,000 cubic feet, calculated using the corrected dimensions of 140 feet in length, 100 feet in width, and an 18-foot ceiling.

Explanation:

To calculate the volume of a warehouse, we use the formula for the volume of a rectangular prism, which is length × width × height. However, the question contains a typo about the width of the warehouse.

We are informed that the correct width is 100 feet, not 610 feet.

Given the corrected dimensions (140 feet by 100 feet with an 18 foot ceiling), we can now calculate the volume of the warehouse.

Volume = length × width × height
= 140 feet × 100 feet × 18 feet
= 252,000 cubic feet.

Therefore, the warehouse has a volume of 252,000 cubic feet of space.

When dealing with the areas of similar polygons, if the ratio of corresponding sides is given, such as 3:4 in this case, the ratio of their areas is the square of the ratio of their sides. This is because the area is a two-dimensional measure, so each dimension is scaled by the ratio.

Given that the area of the larger polygon is 320 , we establish that the scale factor is 3 for the smaller polygon and 4 for the larger one.

To find the area of the smaller polygon, we use the fact that the ratio of the areas is (3/4)2 = 9/16.

This means that the area of the smaller polygon is 9/16 times the area of the larger polygon. Therefore, focusing on the comparison of areas, we calculate:

Area of smaller polygon = (9/16) x Area of larger polygon

= (9/16) x 320

Area of smaller polygon = 180

hello :
let : z = 4-3ii z' = -2+7i
the distance between the points 4-3i and -2+7i is : |z - z' |
|z - z' | = |4-3i+2-7i| = |6-10i | =√(6²+(-10)²) =√136
