Sin M = Opp/Hyp
Reference angle = M
Opp = 3√/21
Hyp = 15
Sin M = (3-√21)/15
Sin M = √21/5
Cos M = Adj/Hyp
Reference angle = M
Adj = 6
Hyp = 15
Cos M = 6/15
Cos M = 2/5
Tan M = Opp/Adj
Reference angle = M
Opp = 3√21
Adj = 6
Tan M = (3√21)/6
Tan M = √21/2

A university dean is interested in determining the proportion of students who receive some sort of financial aid. Rather than examine the records for all students, the dean randomly selects 200 students and finds that 118 of them are receiving financial aid. The 95% confidence interval for p is 0.59 ± 0.07. Interpret this interval.
Select one:
a. 95% of the students receive between 52% and 66% of their tuition in financial aid.
b. We are 95% confident that 59% of the students are on some sort of financial aid.
c. We are 95% confident that between 52% and 66% of the sampled students receive some sort of financial aid.
d. We are 95% confident that the true proportion of all students receiving financial aid is between .52 and .66.
Answers
Confidence interval for 'p' 0.59 ± 0.07 interprets the we are 95% confident that the true proportion of all students receiving financial aid is between .52 and .66.
A confidence interval is a type of interval calculation, obtained from observed data, that contains the true value of an unknown parameter.
It is associated with a confidence level that quantifies the confidence level at which the interval estimates the deterministic parameter.Also it is a term that defines a range of values with the probability to contain a population value that has an actual degree of confidence.This is represented in a situation where population means falls in between upper and lower intervals.Hence, in this case, the correct interpretation is option D: We are 95% confident that the true proportion of all students receiving financial aid is between .52 and .66

How much would you have to deposit today to accumulate the same amount of money that $75 monthly payments at a rate of 3.5% compounding monthly for 10 years in an annuity would
earn?
Round to 2 decimal places and do not include the $
symbol.
Answers
Answer:
To calculate how much you would have to deposit today to accumulate the same amount of money that $75 monthly payments at a rate of 3.5% compounding monthly for 10 years in an annuity would earn, we can use the formula for the present value of an annuity due:
PV = PMT × ((1 - (1 + r/n)^(-n×t)) / (r/n)) × (1 + r/n)
where:
- PV is the present value of the annuity due (the amount you would have to deposit today)
- PMT is the monthly payment ($75)
- r is the annual interest rate (3.5%)
- n is the number of times interest is compounded per year (12 for monthly compounding)
- t is the number of years (10)
PV = 75 × ((1 - (1 + 0.035/12)^(-12×10)) / (0.035/12)) × (1 + 0.035/12) = **$7,360.47**
Therefore, you would have to deposit **$7,360.47** today to accumulate the same amount of money that $75 monthly payments at a rate of 3.5% compounding monthly for 10 years in an annuity would earn.

Answer:

Step-by-step explanation:
Given:
Percent of women = 40%
Percent of women = 35.5%
Total number of people = 1,800
Find:
Number of students
Computation:
Percent of student = 100% - 35.5% - 40%
Percent of student = 24.5%
Number of students = 1,800 x Percent of student
Number of students = 1,800 x 24.5%
Number of students = 441 Students
Are (2, 5) and (5, 2) the same location? Why or why not?
Answers
Answer:
They are not in the same location
Step-by-step explanation:
Well because we have x axis and y axis, x always has to go first. In (2, 5) 2 is first and has to start from the x axis and 5 is the y axis. And the (5,2) is the opposite and the places would be in totally different places on the coordinate plane.
Answer: No
Step-by-step explanation: The order of coordinates for a given point is very important. For example, (2, 5) and (5, 2) represent two very different points on a coordinate system, as shown in the picture below.
A given point, such as (2, 5), is often reffered to as
an ordered pair because the order of coordinates is very important.

cooper's jump rope is for 4 2/5. luke's jump rope is 4 3/4 ft long. whose jump rope is longer? how much longer? show your work
Answers
Answer:
Juke's jump; by 0.35 feet
Step-by-step explanation:
Given that,
Cooper's jump rope is for \(4\dfrac{2}{5}\) feet.
Juke's jump rope is \(4\dfrac{3}{4}\) feet.
Cooper's jump is :
\(4\dfrac{2}{5}=\dfrac{22}{5}\ \text{feet}\\\\=4.4\ \text{feet}\)
Juke's jump is
\(4\dfrac{3}{4}=\dfrac{19}{4}\\\\=4.75\ \text{feet}\)
So, it is clear that Juke's jump is longer than Cooper's jump.
Juke's jump - Cooper's jump = 4.75 - 4.4
= 0.35 feet
or
So, Juke's jump is 375 feet longer.
The probability that a high school senior wins a prestigious scholarship is 0.13. The probability that a high school senior plays a varsity sport is 0.22 . If the probability that someone plays a varsity sport given that they won the scholarship is 0.55 , then what's the probability that someone wins the scholarship given that they play a varsity sport?
Answers
Answer:
0.325
Step-by-step explanation:
Let A represent the event: winning a prestigious scholarship
Let B represent the event: plays a varsity sport
Given
P(A) = 0.13P(B) = 0.22P(plays a varsity sport given that they won the scholarship)= P(B|A) = 0.55We are asked to find P(wins the scholarship given play a varsity sport) = P(A|B)The formula for conditional probability is
\(P(A|B) = \dfrac{P(A \cap B)}{P(B)}\\\\\\P(B|A) = \dfrac{P(A \cap B)}{P(A)}\)where P(A ∩ B) is the probability of both A and B occurring togetherRewriting the above two equations we get
\(P(A \cap B) = P(A|B)P(B) = P(B|A)P(A)\)
→ \(P(A|B)P(B) = P(B|A)P(A)\)
Plugging in known probabilities,
\(P(A|B) (0.22) = P(0.55)(0.13)\)
\(\begin{aligned}P(A|B) & = \dfrac{0.55 \times 0.13}{ 0.22 }\\& = 0.325\end{aligned}\)
Therefore the probability that someone wins the scholarship given that they play a varsity sport is 0.325
Please find the surface area of the cone (image attached) and reduce answer to nearest tenth, if necessary.
Answers
Answer:
\( S.A = 135.6 yd^2 \) (
Step-by-step explanation:
Surface area of cone is given as:
Surface Area (S.A) = πr(r + l)
Where,
\( r = radius = 3 yd \)
\( l = slant height = 11.4 yd \)
Take π as 3.14
Plug the given values into the formula to find the surface area.
\( S.A = 3.14*3(3 + 11.4) \)
\( S.A = 9.42(14.4) \)
\( S.A = 135.6 yd^2 \) (rounded to the nearest tenth)
Jana wrote the ordered pairs (2, 2), (4, 3), and (10, 6). These ordered pairs satisfy a linear

Which ordered pair satisfies the same linear function?

B(14, 7)
C (20, 11)
D(24, 16)
Answers
If Jana wrote the ordered pairs (2, 2), (4, 3), and (10, 6). The ordered pair satisfies the same linear function is :C (20, 11).
Which ordered pair satisfies the same linear function?To determine which ordered pair satisfies the same linear function as the given three ordered pairs, we can use the slope-intercept form of the equation for a linear function, which is y = mx + b, where m is the slope and b is the y-intercept.
First, we can find the slope of the linear function using two of the given ordered pairs. Let's use (2, 2) and (4, 3):
slope = (change in y) / (change in x)
slope = (3 - 2) / (4 - 2)
slope = 1/2
Now that we know the slope of the linear function is 1/2, we can use the point-slope form of the equation for a linear function to find the y-intercept:
y - y1 = m(x - x1), where (x1, y1) is one of the given ordered pairs and m is the slope we just calculated.
Let's use the ordered pair (4, 3) as (x1, y1):
y - 3 = (1/2)(x - 4)
y - 3 = (1/2)x - 2
y = (1/2)x + 1
Now we can substitute the x-coordinate of each of the answer choices into this equation to see which one gives us the corresponding y-coordinate:
For A (12, 8):
y = (1/2)x + 1
y = (1/2)(12) + 1
y = 7
So (12, 8) does not satisfy the same linear function.
For B (14, 7):
y = (1/2)x + 1
y = (1/2)(14) + 1
y = 8
So (14, 7) does not satisfy the same linear function.
For C (20, 11):
y = (1/2)x + 1
y = (1/2)(20) + 1
y = 11
So (20, 11) satisfies the same linear function.
For D (24, 16):
y = (1/2)x + 1
y = (1/2)(24) + 1
y = 13
So (24, 16) does not satisfy the same linear function.
Therefore, the answer is C (20, 11).

The price per gallon of gasoline rose from $2.43 to $3.24 in one year. What is the ratio of the increase in price to the original price?
Answers
The ratio of the increase in price to the original price is 1:3
What are equivalent ratios?
The ratios that are same when compared are called equivalent ratios. The equivalentity of two or more ratios can be determined by comparing them to one another. For instance, 1:2 and 2:4 have the same ratio.
Increase in price = $3.24 - $2.43 = $0.81
ratio of increase of price to original price is
$0.81 : $2.43
= 0.81/2.43
= 1/3
= 1:3
