The radius of the circle with the given chord length is: radius = 7.25
How to find the radius of the circle when given the chord length?The Radius of a Circle based on the Chord and Arc Height helps us to computes the radius based on the chord length (L) and height (h).
The formula for the radius of a circle based on the length of a chord and the height is:
r = (L²/8h) + (h/2)
where:
r is the radius of a circle
L is the length of the chord. This is the straight line length connecting any two points on a circle.
h is the height above the chord. This is the greatest distance from a point on the circle and the chord line.
We are given:
L = 5 + 5 = 10
h = 2
Thus:
r = (10²/8(2)) + (2/2)
r = 6.25 + 1
r = 7.25

The equation of the hyperbola is [tex](x + 3)^2/16 - (y - 5)^2/36[/tex] = 1.
What is hyperbola?The collection of all points in a plane such that the distance between any point on the curve and two fixed points (referred to as the foci) is constant is known as a hyperbola. Hyperbolas are a sort of conic section. A hyperbola contains two distinct branches and has the appearance of two curving branches that are mirror reflections of one another. A hyperbola's center, vertices, co-vertices, foci, and asymptotes are some of its most important characteristics. The center, which is the point around which the hyperbola is symmetric, is the midway of the line segment connecting the vertices.
Given that, the co-vertices are (1, 5) and (-7, 5).
Now, using the midpoint formula we have:
center = ((1+(-7))/2, (5+5)/2) = (-3, 5)
Now, the distance between center and vertex is a = 4.
Also, the distance between the center and each co-vertex is b = 6.
Now, the equation of the hyperbola is:
[tex](x - (-3))^2/4^2 - (y - 5)^2/6^2 = 1\\(x + 3)^2/16 - (y - 5)^2/36 = 1[/tex]

Answer:
[tex]y=5-2x[/tex]
Step-by-step explanation:
You have to give the equation in the form [tex]y=mx+c[/tex], where m is the gradient and c is the y-intercept (where the line crosses the y-axis).
From the graph, we can see the line crossed the y-axis at (0,5), so the y-intercept is (0,5), which means c is 5.
We can work out the gradient with the two points (2,1) and (1,3) by doing:
[tex]\frac{change in y}{change in x} =\frac{1-3}{2-1}=-2[/tex]
So the gradient of the line, m, is -2.
Thus the equation of the line is [tex]y=5-2x[/tex].
true or false: we conduct a test of hypothesis by assuming that ha is correct, since that is the hypothesis we are trying to show is true. group of answer choices true false
Given statement "We conduct a test of hypothesis by assuming that ha is correct, since that is the hypothesis we are trying to show is true." is true. Because we start by assuming that the null hypothesis is correct, not the alternative hypothesis, when conducting a test of the hypothesis.
When conducting a test of hypothesis, we do not assume that Ha (the alternative hypothesis) is correct.
Instead, we begin by assuming that the null hypothesis (H0) is true.
The null hypothesis typically represents a statement of "no effect" or "no difference" between two groups or variables.
The alternative hypothesis (Ha) represents the statement we are trying to prove or gather evidence for but we must start with the assumption that the null hypothesis is correct.
State the null hypothesis (H0) and the alternative hypothesis (Ha).
The null hypothesis typically represents the status quo or a baseline assumption, while the alternative hypothesis represents the claim you want to prove or gather evidence for.
Determine the level of significance (α), which is the probability of rejecting the null hypothesis when it is actually true. Common significance levels are 0.05, 0.01, and 0.001.
Select an appropriate test statistic, which depends on the type of data and the hypothesis being tested. Examples include the t-test, chi-square test, and ANOVA.
Collect data and calculate the value of the test statistic based on the data.
Compare the calculated test statistic value to the critical value for the chosen level of significance.
If the test statistic is more extreme than the critical value, we reject the null hypothesis in favor of the alternative hypothesis.
Otherwise, we fail to reject the null hypothesis.
Hence, the statement is false.

An article on the relation of cholesterol levels in human blood to aging reports that average cholesterol level for women aged 70-74 was found to be 230m/dl. If the standard deviation was 20mg/dl and the distribution normal, what is the probability that a given woman in this age group would have a cholesterol level
a) Less than 200mg/dl
b) More than 200mg/dl
c) Between 190mg/dl and 210mg/dl
d) Write a brief report on the guidance you would give a woman having high cholesterol level in this age group
a) The probability of a given woman in this age group having a cholesterol level less than 200mg/dl is 6.68%.
b) The probability of a given woman in this age group having a cholesterol level more than 200mg/dl is 93.32%.
c) The probability of a given woman in this age group having a cholesterol level between 190mg/dl and 210mg/dl is 15.87%.
d) If a woman in this age group has a cholesterol level higher than 230mg/dl, it is considered high and puts her at risk of heart disease
To calculate the probability of a given woman in this age group having a cholesterol level less than 200mg/dl, we need to find the z-score first. The z-score is the number of standard deviations that a given value is from the mean. The formula to calculate the z-score is:
z = (x - μ) / σ
where x is the given value, μ is the mean, and σ is the standard deviation.
For a cholesterol level of 200mg/dl, the z-score is:
z = (200 - 230) / 20 = -1.5
We can then use a z-table or calculator to find the probability of a z-score being less than -1.5, which is 0.0668 or approximately 6.68%.
Next, to find the probability of a given woman in this age group having a cholesterol level more than 200mg/dl, we can use the same process but subtract the probability of a z-score being less than -1.5 from 1 because the total probability is always 1.
So, the probability of a given woman in this age group having a cholesterol level more than 200mg/dl is:
1 - 0.0668 = 0.9332 or approximately 93.32%.
Finally, to find the probability of a given woman in this age group having a cholesterol level between 190mg/dl and 210mg/dl, we need to find the z-scores for both values.
For a cholesterol level of 190mg/dl, the z-score is:
z = (190 - 230) / 20 = -2
For a cholesterol level of 210mg/dl, the z-score is:
z = (210 - 230) / 20 = -1
We can then use the z-table or calculator to find the probability of a z-score being between -2 and -1, which is 0.1587 or approximately 15.87%.
Finally, a brief report on the guidance that you would give a woman having high cholesterol levels in this age group is:
It is essential to make lifestyle changes such as eating a healthy diet, exercising regularly, quitting smoking, and managing stress to lower cholesterol levels.

The method of completing the square can be used to transform the equation x² - 6x + 8 = 0 into the form (x-p)² = q
Answer:
p = 3, q = 1
Step-by-step explanation:
well, let's think about what (x - p)² actually is.
let's do the multiplication (what a square is) :
(x - p)(x - p) = x² - px - px + p² = x² - 2px + p²
now, we compare the theoretical equation to the actual equation :
x² - 6x + 8 = 0
x² - 2px + p² = q
x² = x² check
-6x = -2px
-6 = -2p
p = -6/-2 = 3
that gives us
x² - 6x + 9 = q
compare this to
x² - 6x + 8 = 0
we subtract the second equation from the first
x² - 6x + 9 = q
- x² - 6x + 8 = 0

I will get you Brainiest!!!
Using probability, there is only one outcome that represents rolling an odd number and landing on blue.
What exactly is probability?
Probability is a measure of the possibility or chance that an event will occur. It is represented by a number between 0 and 1, with 0 representing an improbable occurrence and 1 representing a certain event. A given event's probability is estimated by dividing the number of favourable outcomes by the total number of potential possibilities. Probability theory is frequently used to analyse and forecast the likelihood of occurrences in domains such as statistics, physics, economics, and finance.
Now,
The probability of rolling an odd number is 3/6, which can be simplified to 1/2. The probability of landing on blue= 1/3. Since the events of rolling an odd number and landing on blue are independent, we can multiply the probabilities to find the probability of both events occurring:
(1/2) × (1/3) = 1/6
So, there is only one outcome that represents rolling an odd number and landing on blue. The answer is 1.

1. Suppose we have the following annual risk-free bonds Maturity Price Coupon Rate YTM 1 98 0% 2.01% 2 101 2.48% 3 103 2.91% 4 101 2% 1.73% 5 103 5% 4.32% 39 a) Find the zero rates for all 5 maturities Note: for an extra challenge, try using lincar algebra to find == A + where 98 00 -- 3 103 0 2 2 5 5 0 104 2 0 0 0 0 0 0 1020 5 105 5 1 b) Suppose we have a risk-free security which pays cash flows of $10 in one year, $25 in two years, and $100 in four years. Find its price
a) The zero rates for the five maturities are: 1 year is 2.01%, 2 years is 2.48%, 3 years is 2.77%, 4 years is 1.73%, and 5 years is 4.32%.
b) The price of the security is $128.31.
a) To find the zero rates for all 5 maturities, we can use the formula for the present value of a bond:
PV = C / [tex](1+r)^n[/tex]
where PV is the present value,
C is the coupon payment,
r is the zero rate, and
n is the number of years to maturity.
We can solve for r by rearranging the formula:
r = [tex](C/PV)^{(1/n) }[/tex]- 1
Using the bond data given in the question, we can calculate the zero rates for each maturity as follows:
For the 1-year bond, PV = 98 and C = 0, so r = 2.01%.
For the 2-year bond, PV = 101, C = 2.48, and n = 2, so r = 2.48%.
For the 3-year bond, PV = 103, C = 2.91, and n = 3, so r = 2.77%.
For the 4-year bond, PV = 101, C = 2, and n = 4, so r = 1.73%.
For the 5-year bond, PV = 103, C = 5, and n = 5, so r = 4.32%.
Alternatively, we can use linear algebra to find the zero rates. We can write the present value equation in matrix form:
PV = A × x
where A is a matrix of coefficients, x is a vector of unknowns (the zero rates), and PV is a vector of present values.
To solve for x, we can use the equation:
x = ([tex]A^{-1}[/tex]) x PV
where ([tex]A^{-1}[/tex]) is the inverse of matrix A.
Using this method, we can solve for the zero rates as follows:
[2.01% ]
[2.48% ]
[2.77% ] = x
[1.73% ]
[4.32% ]
PV = [tex]A^{-1}[/tex] x [98]
[101]
[103]
[101]
[103]
PV = [-0.0201]
[ 0.0248]
[ 0.0277]
[-0.0173]
[ 0.0432]
b) To find the price of the security which pays cash flows of $10 in one year, $25 in two years, and $100 in four years, we can use the formula for the present value of a series of cash flows:
PV = [tex]C1/(1+r)^1 + C2/(1+r)^2 + C3/(1+r)^4[/tex]
where PV is the present value, C1, C2, and C3 are the cash flows, r is the zero rate, and the exponents correspond to the number of years until each cash flow is received.
Using the zero rates calculated in part (a), we can calculate the present value of each cash flow:
PV1 = $10 /(1+2.01 % [tex])^1[/tex] = $9.80
PV2 = $25/(1+2.48%[tex])^2[/tex] = $22.15
PV3 = $100/(1+1.73%[tex])^4[/tex] = $81.36
Then, the price of the security is the sum of the present values:
PV = $9.80 + $22.15 + $81.36 = $128.31
Therefore, the price of the security is $128.31.

A primary credit cardholder's card has an APR of 22. 99%. The current monthly balance, before interest, is $4,528. 34. Determine how much more the cardholder will pay, making monthly payments of $200, until the balance is paid off, instead of paying off the current balance in full
The cardholder will pay an additional $1,471.66 in interest by making monthly payments of $200 until the balance is paid off instead of paying off the current balance in full.
First, we need to calculate the total interest that will accrue on the current balance of $4,528.34. We can do this using the formula
Interest = Balance x (APR/12)
where APR is the annual percentage rate and is divided by 12 to get the monthly interest rate. Plugging in the values, we get:
credit card Interest = $4,528.34 x (22.99%/12) = $87.80
So the total interest that will accrue on the current balance is $87.80.
Next, we need to calculate how long it will take to pay off the balance by making monthly payments of $200. We can use a credit card repayment calculator to do this, but we'll use a simplified formula here
Months = -log(1 - (Balance x (APR/12))/Payment) / log(1 + (APR/12))
where Payment is the monthly payment amount. Plugging in the values, we get
Months = -log(1 - ($4,528.34 x (22.99%/12))/$200) / log(1 + (22.99%/12)) = 29.6 months
So it will take about 30 months (or 2.5 years) to pay off the balance by making monthly payments of $200.
Finally, we can calculate how much more the cardholder will pay in total by subtracting the current balance from the total amount paid over 30 months
Total amount paid = $200 x 30 = $6,000
Total interest paid = $6,000 - $4,528.34 = $1,471.66

. which one of the following statements is true? a. if you are given a sample percentage of 43%, you would need to know the sample size in order to convert this percentage to a proportion. b. the test statistic is affected by the size of the sample. c. the larger the p-value, the more evidence you have against the null hypothesis. d. we always begin a hypothesis test by assuming that the null hypothesis is false. e. none of the above statements are true.
If you are given a sample percentage of 43%, you would need to know the sample size in order to convert this percentage to a proportion.
The conversion formula is proportion = percentage/100. However, the proportion alone does not give information about the sample size, which is necessary for inference and hypothesis testing. The other statements are not true.
The test statistic is not affected by the sample size, but its value can be used to determine the significance of a hypothesis test. A larger p-value indicates weaker evidence against the null hypothesis, not stronger evidence. Finally, we assume the null hypothesis is true until we have sufficient evidence to reject it.

Determine the scale ratio for this map given that the distance from Wellspring to Red Creek is 4 inches on the map and 10 miles in reality.
The scale ratio for this map is 0.0000063.
What is scale ratio?
Scale ratio is the ratio between the measurements of an object or distance on a map or drawing and the actual measurements of the object or distance it represents in real life. It allows us to compare and relate the sizes or distances of objects in a drawing or map to their actual sizes or distances in the real world.
The scale ratio can be found by dividing the distance on the map by the corresponding distance in reality:
scale ratio = distance on map / distance in reality
In this case, the distance from Wellspring to Red Creek is 4 inches on the map and 10 miles in reality. So the scale ratio is:
scale ratio = 4 inches / 10 miles
To simplify this ratio, we need to convert the units so that they are the same. Let's convert inches to miles:
1 mile = 63,360 inches
So, we can convert the inches on the map to miles as follows:
4 inches * (1 mile / 63,360 inches) = 0.000063 miles
Now we can rewrite the scale ratio as:
scale ratio = 0.000063 miles / 10 miles
Simplifying this ratio by canceling out the units of miles, we get:
scale ratio = 0.0000063
Therefore, the scale ratio for this map is 0.0000063.

The diameter of a circle is 12.5 cm. What is the circumference of the circle? Question 1 options: 19.63 cm 35. 25 cm 39.25 cm 78.5 cm please tell me quick!!!!
Answer:
The circumference of a circle is given by the formula:
C = πd
where C is the circumference, d is the diameter, and π is a mathematical constant approximately equal to 3.14.
In this case, the diameter of the circle is given as 12.5 cm.
Substituting this value into the formula, we get:
C = π(12.5)
C = 39.25 cm
Therefore, the circumference of the circle is 39.25 cm.
Hence, the answer is 39.25 cm.
On Sunday a local hamburger shop sold 356 hamburgers and cheeseburgers. The number of cheeseburgers sold was three times the number of hamburgers sold. How many hamburgers were sold on Sunday
The number of hamburgers sold on Sunday was 89
How many hamburgers were sold on SundayLet's assume that the number of hamburgers sold on Sunday was x.
According to the problem, the number of cheeseburgers sold was three times the number of hamburgers sold.
Therefore, the number of cheeseburgers sold can be expressed as 3x.
The total number of hamburgers and cheeseburgers sold was 356.
Therefore, we can write an equation to represent this information:
x + 3x = 356
Simplifying the left-hand side of the equation, we get:
4x = 356
Dividing both sides by 4, we get:
x = 89
Therefore, the number of hamburgers sold on Sunday was 89, and the number of cheeseburgers sold was 3 times that, or 267.

The area of (V is 624.36 square meters. The area of sector
SVT is 64.17 square meters. Find the indicated measure.
1. The radius of V is approximately 14.04 meters.2.The circumference of V is approximately 88.24 meters. 3.mST arc is 26.85 degrees. 4.the length of ST arc is approximately 6.61 meters. 5.34.69 meters. 6.88.24m.
Describe Sector?In geometry, a sector is a part of a circle enclosed by two radii and an arc. Essentially, a sector is a slice of a circle. The two radii that form the sector are equal in length and share a common endpoint, which is the center of the circle. The arc of the sector is a portion of the circumference of the circle and its length is proportional to the measure of the central angle that it subtends.
We can use the given information to solve for the following:
1. Radius of V:
The area of a circle is given by the formula A = πr². We are given the area of V as 624.36 square meters, so we can solve for the radius r as:
A = πr²
624.36 = πr²
r² = 624.36/π
r ≈ 14.04 meters
Therefore, the radius of V is approximately 14.04 meters.
2. Circumference of V:
The circumference of a circle is given by the formula C = 2πr. Using the radius we just found, we can solve for the circumference of V as:
C = 2πr
C = 2π(14.04)
C ≈ 88.24 meters
Therefore, the circumference of V is approximately 88.24 meters.
3. mST arc:
The area of the sector SVT is given as 64.17 square meters. The area of a sector is given by the formula A = (θ/360)πr², where θ is the central angle of the sector in degrees. We are not given the value of θ, but we can solve for it as:
A = (θ/360)πr²
64.17 = (θ/360)π(14.04)²
θ ≈ 26.85 degrees
Therefore, the central angle of the sector SVT is approximately 26.85 degrees, and mST arc is also 26.85 degrees.
4. Length of ST arc:
The length of an arc of a circle is given by the formula L = (θ/360)C, where θ is the central angle of the arc in degrees, and C is the circumference of the circle. We can use the values we have already calculated to solve for the length of ST arc as:
L = (θ/360)C
L = (26.85/360)(88.24)
L ≈ 6.61 meters
Therefore, the length of ST arc is approximately 6.61 meters.
5. Perimeter of shaded region (sector):
The perimeter of a sector is the sum of the length of the arc and the lengths of the two radii that form the sector. Using the values we have already calculated, we can solve for the perimeter of the shaded sector as:
Perimeter = L + 2r
Perimeter = 6.61 + 2(14.04)
Perimeter ≈ 34.69 meters
Therefore, the perimeter of the shaded region (sector) is approximately 34.69 meters.
6. Perimeter of unshaded region (remaining circle part):
The perimeter of a circle is given by the formula C = 2πr. Using the radius we previously calculated, we can solve for the perimeter of the unshaded region as:
Perimeter = 2πr
Perimeter = 2π(14.04)
Perimeter ≈ 88.24 meters
Therefore, the perimeter of the unshaded region (remaining circle part) is approximately 88.24 meters.
