Find the equation for a hyperbola centered at (0, 0), with foci at (0,-sqrt73)) and (0,-sqrt73)) and vertices at (0, -8) and (0, 8).
Answers
Answer:
[tex]\dfrac{y^2}{64}-\dfrac{x^2}{9}=1[/tex] .
Step-by-step explanation:
Since vertices lie on y-axis. So, it is a vertical parabola of the form
[tex]\dfrac{(y-k)^2}{a^2}-\dfrac{(x-h)^2}{b^2}=1[/tex]
where, (h,k) is center, [tex](h,k\pm c)[/tex] is focus and [tex](h,k\pm a)[/tex] is vertex.
Center is (0,0). So, h=0 and k=0.
Foci are [tex](0,\pm \sqrt{73})[/tex]. So [tex]c=\sqrt{73}[/tex].
Vertices are [tex](0,\pm 8)[/tex]. So [tex]a=8[/tex].
We know that,
[tex]a^2+b^2=c^2[/tex]
[tex]8^2+b^2=(\sqrt{73})^2[/tex]
[tex]b^2=73-64[/tex]
[tex]b=3[/tex]
Put h=0,k=0, a=8 and b=3 in equation (1).
[tex]\dfrac{(y-0)^2}{8^2}-\dfrac{(x-0)^2}{3^2}=1[/tex]
[tex]\dfrac{y^2}{64}-\dfrac{x^2}{9}=1[/tex]
Therefore, the required equation is [tex]\dfrac{y^2}{64}-\dfrac{x^2}{9}=1[/tex] .
The students at a High School earned money for an international animal rescue foundation. 82 seniors earned an average $26.75 per student, 74 juniors earned an average $12.25 per student, 96 sophomores earned an average $15.50 per student, and 99 freshmen earned an average $10.85 per student. What was the average collection for a student in this school?
A. $16.34
B. $16.13
C. $5.37
D. $16.63
Answers
Answer: B. $16.13
Step-by-step explanation:
Formula : Sum of n observations = Mean x n
Given, 82 seniors earned an average $26.75 per student, 74 juniors earned an average $12.25 per student, 96 sophomores earned an average $15.50 per student, and 99 freshmen earned an average $10.85 per student.
Total students = 82+74+96+99 =351
Sum of earnings of 82 seniors = $26.75 x 82= $2193.5
Sum of earnings of 74 juniors = $12.25 x 74 = $906.5
Sum of earnings of 96 sophomores = $15.50 x 96 = $1488
Sum of earnings of 99 freshmen = $10.85 x 99 = $1074.15
Total earnings = $2193.5 + $906.5+ $1488 +$1074.15
= $5662.15
Average collection = (Total earnings) ÷ (Total students )
= $5662.15÷ 351
≈ $16.13
Hence, the average collection for a student in this school = 16.31
So, the correct option is B.
In meters, find the value of x?
Answers
Answer:
75 meters
Step-by-step explanation:
30/50 = 45/x
x = 75
Answer:
x= 75m
Step-by-step explanation:
If we call the angle in the bottom left θ, then the sinθ=(opposite side)/(hypotenuse).
For the smaller triangle:
sinθ=30/50
And for the bigger triangle:
sinθ=45/x
So:
30/50=sinθ=45/x
30/50=45/x
x=(45•50)/30=2250/30=75
So x= 75 meters

An automotive plant makes the Quartz and the Pacer. The plant has a maximum production capacity of 1200 cars per week, and they can make at most 600 Quartz cars and 800 Pacers each week. If the profit on a Quartz is $500 and the profit on a Pacer is $800, find how many of each type of car the plant should produce.
Answers
Answer:
x=400 and y=800
Step-by-step explanation:
let x be the Quartez and y is Pacer
x+y≤1200 ( maximum production capacity of 1200 cars per week)
0≤x≤600
0≤y≤800
profit : 500x+800y
at a point : x=0 y=800
profit=500x+800y ⇒ 500(0)+800(800)=640000
profit= 500(600)+0=300000 wen x=600(max), y=0
Profit=500(600)+800(600)= 780000
profit =500(400)+800(800)=840000 this is the max profit when
x=400 and y=800
A medical researcher tested a new treatment for poison ivy against the traditional ointment. He concluded that the new treatment is more effective. Explain what P-Value of 0.047 means in this context.
Answers
Answer:
A p-value if 0.047(same as 4.7%) means there is a 4.7% chance that there is no difference in how effective the new treatment is.
Step-by-step explanation:
When we talk of a p-value, we are referring to a conditional probability. What it tells us is the probability of getting results which are at least as unusual as the observed statistics in a case where we are given that the null hypothesis is not false.
A p-value if 0.047(same as 4.7%) means there is a 4.7% chance that there is no difference in how effective the new treatment is.
So what this means is that, in this case it is better that more data is collected to enable us know how effective the new treatment is

B. x - 3
C. x + 2
D. x + 4
Answers
1,3,4 that is the answer
Answer:
The answer is option D.Step-by-step explanation:
x³ + 6x² + 5x - 12
A factor of the polynomial is the value of x when substituted into the expression will make it zero
Choosing x + 4
x = - 4
We have
(- 4)³ + 6(- 4)² + 5(- 4) - 12
-64 + 96 - 20 - 12 = 0
Since the result is zero
x + 4 is a factor of the polynomial

Suppose you computed a 95% confidence interval for the difference in mean weight between two species of snakes in a large nature reserve (species #1 – species #2), and your interval is –3.6 to 61.6 ounces. What can you conclude?
Answers
Answer:
1. In a situation were we are willing to use 90% confidence, this means we could say that the observed difference that we have in the sample means tend to represents a real difference in the population means.
2. We cannot actually say because even with 95% confidence, that is the observed difference in sample means tend to as well represents a real difference in the population means.
3. Because the interval extends further in the positive direction than the negative direction this means that the evidence suggests that species #1 tend to weighs more than species #2 on average, but we can't actually say for sure.
Step-by-step explanation:
The following are what I will conclude about based on the information given in the question.
1. In a situation were we are willing to use 90% confidence, this means we could say that the observed difference that we have in the sample means tend to represents a real difference in the population means.
2. We cannot actually say because even with 95% confidence, that is the observed difference in sample means tend to as well represents a real difference in the population means.

Answers
Answer: 11 units
Step-by-step explanation:
Given: On a coordinate plane, the coordinates of vertices R and T for a polygon are R(−6, 2) and T(5, 2).
To find : length of Side RT of the polygon.
Using distance formula to find distance between (a,b) and (c,d):
[tex]d=\sqrt{(d-b)^2+(c-a)^2}[/tex]
Length of RT = [tex]\sqrt{(2-2)^2+(5-(-6))^2}[/tex]

At a figure skating competition, the order of skaters is randomly selected. If
there are 20 skaters, what is the probability that Christie, Taylor, and Jona will
skate first, second, and third, respectively?
Answers
Answer: [tex]\dfrac{1}{6840}[/tex]
Step-by-step explanation:
According to the permutations:
The arrangement of n things in an order = n!
If we fix that the first, second, and third person for skating, then we to arrange only 17 of the skaters.
Number of ways to arrange rest of 17 skaters = 17!
Number of ways that Christie, Taylor, and Jona will skate first, second, and third, respectively = 1 x 17!=17!
Number of ways to arrange all 20 skaters = 20!
Now, the required probability = [tex]\dfrac{\text{favourable outcomes}}{\text{total ways}}[/tex]
[tex]=\dfrac{17!}{20!}\\\\=\dfrac{1}{20\times19\times18}\\\\=\dfrac{1}{6840}[/tex]
Hence, the required probability = [tex]\dfrac{1}{6840}[/tex]

Subtract straight down. The x terms subtract to 5x-2x = 3x. The y terms subtract to 3y-3y = 0y = 0, so the y terms go away and are eliminated. The terms on the right hand side subtract to 31-25 = 6.
After all that subtraction, we end up with the equation 3x = 6 which solves to x = 2 after dividing both sides by 3.
Use x = 2 to find the value of y
5x+3y = 31
5(2)+3y = 31
10+3y = 31
3y = 31-10
3y = 21
y = 21/3
y = 7
or
2x+3y = 25
2(2)+3y = 25
4+3y = 25
3y = 25-4
3y = 21
y = 21/3
y = 7
Using either equation has x = 2 lead to y = 7.
Therefore, the solution is (x,y) = (2,7)
If you were to graph the two original equations, then they would intersect at (2,7).

Find the amount and present value of 10 quarterly payments of $ 1500, if the interest rate is 25% compounded each month.
Answers
Given Information:
Monthly payment = MP = $1500/4 = $375
Monthly interest rate = r = 25/12 = 2.083%
Required Information:
Present Value = ?
Answer:
[tex]PV = \$10,110[/tex]
Explanation:
n = 10*4
n = 40 monthly payments
The present value is found by
[tex]$ PV = MP \times \frac{ (1 - \frac{1}{(1+r)^n} )}{r} $[/tex]
Where r is monthly interest rate.
MP is the monthly payment.
[tex]$ PV = 375 \times \frac{ (1 - \frac{1}{(1+0.02083)^{40}} )}{0.02083} $[/tex]
[tex]PV = 375 \times (26.96)[/tex]
[tex]PV = \$10,110[/tex]
Therefore, $10,110 is the present value of 10 quarterly payments of $1500 each at 25% interest rate compounded each month.
