B. A= 142, c=38, t =38
Answer:
a. 27° + (2x° + x°) = 180° (linear pair)
27° + 3x° = 180°
3x° = 180°-27°
x° = 153°/3
x° = 51°
2x° = 2×51 = 102°
b. a° = 142° (vertically opposite)
c° + a° = 180° (linear pair)
c° = 180° - 142°
c° = 38°
i° = c° = 38° (vertically opposite)

whats the answer? And equation?
Step-by-step explanation:
What is its domain?
What is its range?
Write the answer in interval notation.
Answers
Answers:
Domain = [-3, 3]
Range = [-1, 2]
=============================================
Explanation:
The domain is the set of all allowed x inputs. Visually, the left-most point is when x = -3, so -3 is the smallest allowed x input. We have a closed circle at this endpoint, so this endpoint x value is included. In contrast, if you had an open circle, then you would exclude the endpoint.
Similarly, we have a closed endpoint at the other side as well when x = 3. This is the largest allowed x value. The domain is the set of x values such that [tex]-3 \le x \le 3[/tex] meaning x is between -3 and 3, including both endpoints. This translates to the interval notation of [-3, 3]. The square brackets say "include the endpoint".
------------
The range is the set of possible y outputs of a function. The lowest the function goes is when y = -1, and the highest is when y = 2. We include both endpoints. The range as a compound inequality is [tex]-1 \le y \le 2[/tex] which converts to the interval notation of [-1, 2]

A statewide real estate sales agency, Farm Associates, specializes in selling farm property in the state of Nebraska. Its records indicate that the mean selling time of farm property is 90 days. Because of recent drought conditions, the agency believes that the mean selling time is now greater than 90 days. A statewide survey of 100 farms sold recently revealed that the mean selling time was 94 days, with a standard deviation of 22 days.
Required:
At the 0.10 significance level, has there been an increase in selling time?
Answers
Answer:
The right answer is "1.818".
Step-by-step explanation:
The given values are:
a = 0.1
[tex]\bar{x} = 94[/tex]
[tex]\mu = 90[/tex]
Now,
The test statistic will be:
⇒ [tex]t=\frac{\bar{x}-\mu}{\frac{s}{vn} }[/tex]
On substituting the given values, we get
⇒ [tex]=\frac{94-90}{\frac{22}{10} }[/tex]
⇒ [tex]=\frac{4}{2.2}[/tex]
⇒ [tex]=1.818[/tex]
