Answers
Answer:
13) B
14) A
Step-by-step explanation:
13) Knowing that the interior angles of a triangle add up to 180, we can see that angle A is 53°. To find length c, we can use either sine or cosine. Let's use sine:
sin 37° = b/c = 15.9/c ---> c = 15.9/sin 37 = 26.4
To solve for side a, use cosine:
cos 37° = a/26.4 ---> a = 26.4cos37 = 21.1
14) Again, knowing that the interior angles of a triangle add up to 180, we know that angle B is 52°. This time,let's use cosine (although you may choose sine if you want):
cos 38° = b/16 ---> b = 16cos38 = 12.6
To find side a, use sine:
sin 38° = a/16 ---> a = 16sin38 = 9.9

write the equation for a parabola with a focus at (-3,-5) and a directrix at x=-7
x=
Answers
Answer:
hope this helps
Step-by-step explanation:
equation for a parabola is:
What is parabola?The parabola is the locus of points in that plane that are equidistant from both the directrix and the focus.
Given: focus= (3,-5), directrix at x =-7.
To find equation of parabola we will use distance formula,
√(x+7)²=√(x+3)² + (y+5)²
(x+7)²=(x+3)² + (y+5)²
x²+14x+49= x²+9+6x + (y+5)²
8x + 40 = (y+5)²
x= (y+5)²/8 -5
Hence, the equation of parabola is x= (y+5)²/8 -5

It has been reported that men are more likely than women to participate in online auctions. In a recent survey, 65% of repondents reported that they had participated in an online auction. In this same survey, 45% of repondents were men and 38% were men who had participated in online auctions. What is the probability that a respondent selected at random is female and has never participated in an online auction?
A. 0.62
B. 0.72
C. 0.38
D. 0.28
E. 0.07
Answers
Answer:
Hence, the Female and not participated is [tex]\frac{28}{100}=0.28\%[/tex]
Step-by-step explanation:
Let Total respondents [tex]=100[/tex]
Participated in online action [tex](P)=65[/tex]
Men [tex](m)=45[/tex] and Women [tex](F)=100-45=55[/tex]
Male and participated [tex](M\; \text{and}\;P)=38[/tex]
Female and participated [tex](F\; \text{and}\;P)=65-38=27[/tex]
Male and not participated is [tex]45-38=7[/tex]
Female and not participated is [tex]55-27=28[/tex]
Therefore, the Female and not participated is [tex]\frac{28}{100}=0.28\%[/tex]
Hence, the correct option is [tex]D[/tex].
You tell your 3 friends that you are going to a magic show. It turns out, in an amazing coincidence, they each
have tickets to the same magic show. The dissapointing part is that all 4 of you are sitting in different places at
the event. During the show, the magician asks for 4 brave volunteers. If you and all of your friends raise your
hands as well as 16 other audience members for a grand total of 20 volunteers.
What is the probability that you and your 3 friends will be selected. Write your answer as a simplified
fraction.
Answers
Answer:
[tex]\frac{1}{4845}[/tex] probability that you and your 3 friends will be selected.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question, the order in which the volunteers are chosen is not important, which means that the combinations formula is used to solve this question.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
Desired outcomes:
You and the 3 friends(4 people), from a set of 4. So
[tex]D = C_{4,4} = \frac{4!}{4!0!} = 1[/tex]
Total outcomes:
20 people from a set of 20. So
[tex]T = C_{20,4} = \frac{20!}{4!16!} = 4845[/tex]
Probability:
[tex]p = \frac{D}{T} = \frac{1}{4845}[/tex]
[tex]\frac{1}{4845}[/tex] probability that you and your 3 friends will be selected.
Assume you have five candidates for recruitment and their scores on interview and job knowledge test is below. The interview is measured on scale of 1-25 points and job knowledge is measured on a scale of 1-100 points. Based on the scores of these two tests for the five candidates, who would you select as a finalist. Please note that you need to use the method we used in class to find out the finalist for selection. Describe the answer with the appropriate calculations as we did in the exercise in class.
Answers
Answer: Hi your question is incomplete below is the missing part
Candidate Interviewscore Job Knowledge Test Score
Frank. 14 89
Sally 21 77
Lilly 20 75
Peter 17 82
Jordyn 19 80
Answer : Select Sally because she has the highest Test score
Step-by-step explanation:
For Franck :
Interview score / 25 = 14 / 25 = 0.56
Job knowledge score = 89 /100 = 0.89
Test score = 0.56 + 0.89 = 1.45
For Sally
interview score = 21 / 25 = 0.84
Jon knowledge = 77 / 100 = 0.77
Test score = 0.84 + 0.77 = 1.62 ( Highest test score )
Repeat the same procedure for Lilly , Peter and Jordyn
Lily test score = 1.55
Peter test score = 1.5
Jordyn test score = 1.56
conclusion : select Sally as a Finalist

∑(-1/2)^K
k=0
1. There are ____ terms.
2. The sign of each term in the series ___.
3. What is the last term in this series?
Answers
Answer:
Use the attachment below.
Step-by-step explanation:
There will be 5 terms, there will be an alternative sign of the series and their last term will be 1/16.
What is a series?A sequence's series is the total number of terms in the sequence.
A series follows some pattern for example if you take data set of natural numbers then there will be a sequence of that data and something will be due to that we can form that series.
Given that the series
∑(-1/2)^K and this summation goes from k =0 to k = 4
Now the question is asking how many terms are in there, the sign of each term in the series, and the last term in this series.
Now if you take k =0 and find the first term then it will be
(-1/2)⁰ = 1 so the first term will be 1.
Similarly, you can put k =1,2,3,4 so there will be a total of 5 terms.
The sign of each term will be alternative since because of negative somethings power will be positive if power is odd and negative if power is even.
In the last term put k = 4, and you will get (-1/2)⁴ = 1/16.
