Step-by-step explanation:
sin = opp/hyp
The opposite side to angle A is side BC, which has a length of 60.
The hypotenuse is AB, which we can find the length of using the Pythagorean theorem. Using the Pythagorean theorem, we get that AB=100.
So the sine of A = 60/100 = 3/5

Answer:
to know what scale to use you divide the the highest score by the number of hozirontal line (feint/lighter drawn lines) which are 14.
so 260 ÷ 14 equals = 18.57
I then rounded the 18.57 to the nearest 10th = 20.
so the scale used is 20s
Classify the triangle by its angles.
Answers
Answer:
D. obtuse
Step-by-step explanation:
The largest angle tells you the sort of triangle it is. Here, the largest angle is more than 90°, so the triangle is classified as obtuse.
__
If it were exactly 90°, the triangle would be a right triangle. A largest angle less than 90° means the triangle is an acute triangle.
_____
Additional comment
The two angles opposite the obtuse angle have the same measure. That means the triangle can be further classified as isosceles. In an equilateral triangle, all three angles have the same measure: 60°.

Why is a convergent and b divergent?
Answers
Part (a)
This sequence is convergent because all we care about are the leading terms for the numerator and denominator. As n gets really large, the leading terms dictate what happens.
The leading term up top is 9n
The leading term down below is 7n
Divide the two items to get (9n)/(7n) = 9/7
We don't have to worry about dividing by zero because n will go off to infinity, and as it does so, the sequence [tex]\{a_n\}[/tex] converges to 9/7
========================================================
Part (b)
As n heads to infinity, the terms of the sequence are approaching 9/7 (they never quite hit the exact value though).
Note how 9/7 = 1.2857 approximately which is larger than 0
So effectively for very large values of n, we're adding on 1.2857 each time or close to it, meaning that this infinite series diverges.
------
For a series like this to converge, the answer to part (a) must be 0. This way at some point, we're effectively adding 0 to the series and we approach some fixed sum.
For example, consider the sequence 1/(7n+1)
As n goes to infinity, the terms of the sequence approach 0
This means that for some very large n, the 1/(7n+1) is basically 0 and we aren't adding much onto the sum to change it. So this sum will converge to a fixed value.

Under her cell phone plan, Micaela pays a flat cost of $47 per month and $5 per gigabyte. She wants to keep her bill at $68.50 per month. Write and solve an equation which can be used to determine xx, the number of gigabytes of data Micaela can use while staying within her budget.
Answers
Answer:
≤ 4.3 gigabytes
Step-by-step explanation:
Flat fee + cost for x gigabytes = her budget
47 + 5 * x ≤ 68.50
5x = 68.50 - 47 ≤ 21.50
x ≤ 21.50/5 = 4.3 gigabytes
Micaela can use approximately 4.3 gigabytes of data while staying within her budget of $68.50 per month.
Let, "x" to represent the number of gigabytes of data Micaela can use while staying within her budget.
The total cost can be calculated by adding the flat cost of $47 to the cost based on the gigabytes used ($5 per gigabyte):
Total Cost = Flat Cost + (Cost per Gigabyte * Number of Gigabytes)
Given that Micaela wants to keep her bill at $68.50 per month, we can set up the equation:
68.50 = 47 + 5x
Now, solve for x:
68.50 - 47 = 5x
21.50 = 5x
Divide both sides by 5:
x = 21.50 / 5
x = 4.3
So, Micaela can use approximately 4.3 gigabytes of data while staying within her budget of $68.50 per month.

Emma measured a line to be 16 inches long. If the actual length of the line is 15.3 inches, then what was the percent error of the measurement, to the nearest tenth of a percent?
Answers
Answer:
4.6% (nearest tenth)
Step-by-step explanation:
percent error = (|approx - actual| ÷ actual) × 100
percent error = (|16 - 15.3| ÷ 15.3) × 100
= 4.6% (nearest tenth)
[tex] \sf\% \: error = \frac{ |approx - actual| }{actual} \times 100[/tex]
Approx = 16Actual = 15.3[tex] \tt\% \: error = \frac{ |16 - 15.3| }{15.3} \times 100[/tex]
[tex] \tt\% \: error = \frac{ |0.7| }{15.3} \times 100[/tex]
[tex] \tt\% \: error = \frac{ |0.7| }{ \frac{153}{10} } \times 100[/tex]
[tex] \tt\% \: error = \frac{0.7}{ \frac{153}{10} } \times 100[/tex]

Answer:
210 mph
Step-by-step explanation:
speed of jet = x
headwind: speed = x - 27
time taken = 1134.6/(x - 27)
tailwind: speed = x + 27
time taken = 1469.4/(x + 27)
same amount of time:
1134.6/(x - 27) = 1469.4/(x + 27)
Cross multiply,
1134.6(x + 27) = 1469.4(x - 27)

Step-by-step explanation:
We need to make [tex]\frac{3}{10}[/tex] and [tex]\frac{5}{9}[/tex] have the same denominator, or bottom half, before we can subtract them.In order to do this, we need to find a number that both 10 and 9 (the bottom numbers) both go into. (Hint! Multiplying them together usually helps!)This number is 90. (See? 10 • 9 = 90!)Since we multiplied 10 by 9 to get 90, we need to multiply the top (3) by 9 too, to get us [tex]\frac{27}{90}[/tex].We multiply [tex]\frac{5}{9}[/tex] by 10 to get us [tex]\frac{50}{90}[/tex].Now we can subtract 27 [tex]\frac{27}{90}[/tex] and 12 [tex]\frac{50}{90}[/tex].27 - 12 = 15 (big numbers)27 - 50 = -23 (fractions)Now we have - 15 [tex]\frac{23}{50}[/tex]If I am incorrect in my reasoning, please let me know so that I can plan better for my future answers.

At a Clover City Council meeting, a plan to fund more sign language programs was presented. The reasoning behind the request was that less than 25% of parents with hearing-impaired children have the ability to pass a sign-language exam. If this is true, the council will agree to fund more programs for these parents. The council decides to take a 175-person volunteer sample of parents in Clover City that have children with auditory issues and conduct a significance test for H0: p = 0.25 and Ha: p < 0.25, where p is the proportion of these parents that can pass the sign language exam. They will perform the significance test at a significance level of α = 0.05 for the hypotheses.
Part A: Describe a Type II error that could occur. What impact could this error have on the situation? (3 points)
Part B: Out of the 175 volunteer parents of children with hearing problems, 54 passed, resulting in a p-value of 0.96. What can you conclude from this p-value given the data of the 175 parents is sufficient to perform a significance test for the hypotheses? (4 points)
Part C: What possible defect in the study can you find in Part B? Explain. (3 points)
Answers
Part A: A Type II error in this context is failing to reject the null hypothesis that 25% of parents with hearing impaired children have the ability to pass a sign-language exam when actually less than 25% are able to pass it.
Part B: We fail to reject the null hypothesis because the p-value of 0.96 is larger than α = 0.05. The evidence is not substantial that the proportion of parents with hearing impaired children in Clover City who are able to pass a sign language exam is less than 0.25. The sample proportion of phat = 0.96 is greater than 0.25.
Part C: The sample of 175 parents with hearing impaired children in Clover City was a group of volunteers, so most likely they were confident in their ability to pass a sign language exam which could better the chances of more passing sign language exams.
