Answer:

x=3, x=-4

Explanation:

x² +x -12

= x² +4x-3x-12

= x(x+4) -3(x+4)

= (x-3)(x+4)

The process of subduction takes place when
statuscvo [17]

Answer:

tectonic plates collide

Explanation:

The process of subduction occurs when two or more tectonic plates move toward one another, thus they collide, or rather form a convergent plate boundary. When the case is that there is an oceanic and continental tectonic plates that collide, then we have the formation of a subduction zone. In the subduction zone, we have a process in which the oceanic tectonic plate is moving below the continental tectonic plate, and as it does, it gradually moves down toward the mantle. Once the oceanic crust comes in contact with the mantle, it starts to melt because of the high temperature, thus it is getting recycled. On this kind of place, the volcanic activity and the earthquakes are common things that happen pretty much every day.

ddd [48]
Having experienced the same thing in my job, I think the most important reason for taking action after an error is that you did not want for other people to experience the consequences. This is especially true if the job is concerned with people as the direct clients or consumers.

A survey asked 26 adults how many years of education they had. The sample mean was 13.03 with a standard deviation of 3.22. It i
yulyashka [42]

Answer: (11.95, 14.11)

Explanation:

Let x be a random variable that represent the number of years of education.

Given: Sample size : n= 26

Sample mean : \overline{x}=13.03

Sample standard deviation : s = 3.22

Significance level : \alpha=100\%-90\%=10\%=0.1

Degree of freedom: df = n-1 = 25

Critical t-value for \alpha=0.1 and df = 25 will be

t_{\alpha/2, df}=t_{0.05,25}=1.7081

90% confidence interval for mean:

\overline{x}\pm t_{\alpha/2,df}\dfrac{s}{\sqrt{n}}\\\\=13.03\pm (1.7081)\dfrac{3.22}{\sqrt{26}}\\\\=13.03\pm  (1.7081)\dfrac{3.22}{5.09902}\\\\=13.03\pm 1.08\\\\=(13.03-1.08,\ 13.03+1.08)\\\\ =(11.95,\ 14.11)

A 90% confidence interval for the mean number of years of education = (11.95, 14.11)

A European visitor to the United States asked a taxi driver, "Can you please a ride to the airport me give?" This visitor has ap
ad-work [718]

Answer:

B. syntax

Explanation:

  • Phonemes: the smallest sound unit of speech distinguishing one word from another, for example, the first letter in tan and pan.
  • <em>Syntax is the format in which we organize words and phrases to create a coherent sentence.</em>
  • Semantics is the relationship between words we use and their meanings.
  • Morphemes are the smallest units of meaning in a language, for example in the word boys, "boy" and "s" are two morphemes.

<em>In the sentence "Can you please a ride to the airport me give?" the words are incorrectly organized, therefore there's a lack of syntax.</em>

I hope you find this information useful and interesting! Good luck!
