Step-by-step explanation:
8x² -16 -28x , rearrange it so the exponents will be going form highest to lowest
8x²-28x -16, factor 4
4(2x² -7x -4),
to get 2x² we need to multiply an x and a 2x
to get -4 we need to multyply 1 and -4 or -1 and 4 or 2 and -2 (can use trial and error method here)
4(x -4)(2x +1)
Check
4(x-4)(2x+1) = (4x -16)(2x+1) = 8x² +4x -32x -16 = 8x²-28x -16
In 2011, Japan experienced an intense earthquake with a magnitude of 9.1 on the Richter scale. In 2003, Japan experienced another intense earthquake that measured 8.3 on the Richter scale. Compare the intensities of the two earthquakes. Use a logarithmic model to solve. Round to the nearest whole number.
Answers
Answer:
The intensity of the 2011 earthquake was about 6 times the intensity of the 2003 earthquake.
Step-by-step explanation:
To compare the intensities, we first need to convert the magnitudes to intensities using the log formula. Then we will set up a ratio to compare the intensities.
Convert the magnitudes to intensities and write them in exponential form.
R=logI
2011 earthquake:
9.1I=logI=109.1
2003 earthquake:
8.3I=logI=108.3
Form a ratio of the intensities.
intensity for 2011intensity for 2003
Substitute in the values and divide by subtracting the exponents to find
109.1108.3100.8≈6.
The intensity of the 2011 earthquake was about 6 times the intensity of the 2003 earthquake.
Your answer:
The intensity of the 2011 earthquake was about 15 times the intensity of the 2003 earthquake.
The intensities of the two earthquakes will be 6.3095.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
In 2011, Japan encountered a serious quake with an extent of 9.1 on the Richter scale. In 2003, Japan encountered another extraordinary seismic tremor that deliberate 8.3 on the Richter scale.
The intensity of the earthquake is given as,
㏒ (I₁ / I₂) = M₁ - M₂
㏒ (I₁ / I₂) = 9.1 - 8.3
Simplify the equation, then we have
㏒ (I₁ / I₂) = 9.1 - 8.3
㏒ (I₁ / I₂) = 0.8
Take anti log, then we have
(I₁ / I₂) = 6.3095
The intensities of the two earthquakes will be 6.3095.

Answers
Answer:

Step-by-step explanation:
The order in which the brands are chosen is not important. So we use the combinations formula to solve this question.
Combinations formula:
\(C_{n,x}\) is the number of different combinations of x objects from a set of n elements, given by the following formula.
\(C_{n,x} = \frac{n!}{x!(n-x)!}\)

Which of the following is false about the central limit theorem (CLT)? O If we take more samples from the original population, the sampling distribution is more likely to be nearly normal. O If the population distribution is normal, the sampling distribution of the mean will also be nearly normal, regardless of the sample size. O As the sample size increases, the sampling distribution of the mean is more likely to be nearly normal, regardless of the shape of the original population distribution. O The CLT states that the sampling distribution will be centered at the true population parameter.
Answers
Only the first statement is false. The rest are true statements about the Central Limit Theorem.
The Central Limit Theorem (CLT) is a fundamental theorem in probability and statistics which states that, given a sufficiently large sample size from a population with a given mean and standard deviation, the sampling distribution of the mean will be nearly normal, regardless of the shape of the original population distribution.
It is important to note that the first statement presented is false. Taking more samples from the population will not necessarily result in a more normal sampling distribution. The CLT does not guarantee that the sampling distribution will be normally distributed, only that it is more likely to be so as the sample size increases.
The second statement is true. If the population distribution is normal, the sampling distribution of the mean will also be nearly normal, regardless of the sample size. The third statement is also true. As the sample size increases, the sampling distribution of the mean is more likely to be nearly normal, regardless of the shape of the original population distribution.
Finally, the fourth statement is also true. The CLT states that the sampling distribution will be centered at the true population parameter. This means that the mean of the sampling distribution will be equal to the mean of the population.

Answers
Answer:
about 1.1%
Step-by-step explanation:
Given a moon has a diameter of 22% of the diameter its planet, you want the volume of the moon as a percent of the planet's volume.
Scale factorThe ratio of moon diameter to planet diameter is given as 22%. The ratio of moon volume to planet volume will be the cube of this scale factor:
moon volume / planet volume = (0.22)³ ≈ 0.0106 = 1.06%
The volume of the moon is about 1.1% of the volume of the planet.

Shoppers at the mall the day before Christmas does not guarantee every shopper in the population has an equal chance to be in the sample Surveying shoppers the day before Christmas is a convenience sample, so it is a simple random sample Surveying shoppers at the mall the day after Christmas may not be a good represenation of all shoppers in the city. Having the reporter ask questions is not a double-blind study.
Answers
The correct option is A shopping center surveys conducted the day before Christmas do not guarantee that every shopper in the population will be included in the sample.
Given that,
The day before Christmas, a reporter from a nearby television station goes to the city's brand-new, upmarket retail center to speak with customers. The first 25 customers he encounter outside one of the mall's department stores are questioned. He inquires as to whether they have a positive, neutral, or negative overall opinion of Christmas shopping.
We have to select the correct option why it might be dangerous to assume that the first 25 customers at this store are representative of all customers in the city.
We know that,
A non-probability sampling technique called convenience sampling includes taking a sample from the nearest area of the population. It is a convenience sample because the reporter in the scenario asked the first 25 people he saw outside one of the department stores at the mall. Each candidate does not have an equal chance of being included in the convenience sample.
The right response is option (A): Shopping center surveys conducted the day before Christmas do not guarantee that every shopper in the population will be included in the sample.

cell phone?
Answers
Answer:
$578.33
Step-by-step explanation:
To get 5% of the original cost you need to multiply by 0.05
550.79 • 0.05 = 27.5395
27.5395 is 5% of 550.79
Since the price is marked up 5% you will need to add 27.5395 to 550.79
550.79 + 27.5395 = 578.3295
Then you will round your answer to 578.33

Subtract 18 from each side
9x+18-18 = 90-18
9x = 72
divide by 9
9x/9 = 72/9
x = 8
AOB = 6x - 12
