The answer is 140°
Because we can use exterior angle property here
Exterior angle property : It states that exterior angle is the sum of two opposite interior angles
y = 120 + 20 = 140°
Answer:
140 degrees
Step-by-step explanation:
A triangle's sum of interior angles is 180.
120+20=140
180-140=40
So X= 40.
X and Y are supplementary, so they both add up to 180.
180-40=140
Therefore, Y=140.

You want to estimate the mean hourly yield for a process that manufactures an antibiotic. You observe the process for 100 hourly periods chosen at random, with the results of 32 ounces per hour and a standard deviation of 7 ounces. Calculate the 95% margin of error (in ounces per hour). (Round your answers to three decimal places.)
Answer:
The margin of error for the 95% confidence interval is of 1.389 ounces per hour.
Step-by-step explanation:
We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 100 - 1 = 99
95% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 99 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.95}{2} = 0.975[/tex]. So we have T = 1.9842
The margin of error is:
[tex]M = T\frac{s}{\sqrt{n}}[/tex]
In which s is the standard deviation of the sample and n is the size of the sample.
Then
[tex]M = T\frac{s}{\sqrt{n}}[/tex]
[tex]M = 1.9842\frac{7}{\sqrt{100}}[/tex]
[tex]M = 1.389[/tex]
The margin of error for the 95% confidence interval is of 1.389 ounces per hour.

Which figure correctly shows a horizontal reflection of the illustration?
Answer:
Step-by-step explanation:
B
Write an recursive formula for An, the nth term of the sequence
5, -2, -9,
Given:
The given sequence is:
[tex]5,-2,-9,...[/tex]
To find:
The recursive formula for [tex]a_n[/tex], the nth term of the sequence.
Solution:
We have,
[tex]5,-2,-9,...[/tex]
Here, the first term is 5.
[tex]-2-5=-7[/tex]
[tex]-9-(-2)=-9+2[/tex]
[tex]-9-(-2)=-7[/tex]
The common difference is -7.
The recursive formula for the nth term of the sequence is
[tex]a_n=a_{n-1}+d[/tex]
Where, [tex]d[/tex] is the common difference.
Putting [tex]d=-7[/tex] in the above formula, we get
[tex]a_n=a_{n-1}+(-7)[/tex]
[tex]a_n=a_{n-1}-7[/tex]
Therefore, the recursive formula for the nth term of the sequence is [tex]a_n=a_{n-1}-7[/tex].

A recent study of 750 Internet users in Europe found that 35% of Internet users were women. What is the 95% confidence interval of the true proportion of women in Europe we use the Internet
Answer:
The 95% confidence interval for the true proportion of internet users who are women in Europe is (0.3159, 0.3841).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
A recent study of 750 Internet users in Europe found that 35% of Internet users were women.
This means that [tex]n = 750, \pi = 0.35[/tex]
95% confidence level
So [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].
The lower limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.35 - 1.96\sqrt{\frac{0.35*0.65}{750}} = 0.3159[/tex]
The upper limit of this interval is:
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.35 + 1.96\sqrt{\frac{0.35*0.65}{750}} = 0.3841[/tex]
The 95% confidence interval for the true proportion of internet users who are women in Europe is (0.3159, 0.3841).

An alarming number of U.S. adults are either overweight or obese. The distinction between overweight and obese is made on the basis of body mass index (BMI), expressed as weight/height2. An adult is considered overweight if the BMI is 25 or more but less than 30. An obese adult will have a BMI of 30 or greater. According to a January 2012 article in the Journal of the American Medical Association, 33.1% of the adult population in the United States is overweight and 35.7% is obese. Use this information to answer the following questions.
a. What is the probability that a randomly selected adult is either overweight or obese? (Round your answer to 3 decimal places.)
b. What is the probability that a randomly selected adult is neither overweight nor obese? (Round your answer to 3 decimal places.)
c. Are the events "overweight" and "obese" exhaustive?
A. Yes because you cannot be both overweight and obese.
B. Yes because you can be both overweight and obese.
C. No because you may either be overweight or obese.
D. No because you may be neither overweight nor obese.
Answer:
a. The probability that a randomly selected adult is either overweight or obese is:
= 68.8%.
b. The probability that a randomly selected adult is neither overweight nor obese is:
= 31.2%
c.
D. No because you may be neither overweight nor obese. The events "overweight" and "obese" are not exhaustive.
Step-by-step explanation:
Overweight adult = BMI ≥ 25 but < 30
Obese adult = BMI ≥ 30
Journal of the American Medical Association:
Overweight adult population in the United States = 33.1%
Obese adult population in the United States = 35.7%
The probability that a randomly selected adult is either overweight or obese = Percentage of overweight adult population + Percentage of obese adult population
= 33.1% + 35.7%
= 68.8%
The probability that a randomly selected adult is neither overweight nor obese = 1 - 68.8%
= 31.2%
The events "overweight" and "obese" can only be exhaustive if their combined probabilities of occurrence equals 1 or 100%.

Solve the exponential equation: 6–2x = 62 – 3x
Answer:
the answer should be 56 :)
Step-by-step explanation:
Answer:
x=56
Step-by-step explanation:
Try to end up with only a single variable on one side.
Step 1: Add 3x to each side of the equation to keep them both equal. Example: 6-2x+3x=62-3x+3x
or
6+x=62
Step 2: Subtract 6 from both sides. Example:
6+x-6=62-6
or
x=56
Step 3: You found the answer. Hope this helps and is correct.
