x =3 and y = 4 , these two perpendicular bisectors will come together. These are the triangle's circumcenter's coordinates.

What is perpendicular in triangle?

The sides of a triangle are divided into two equal portions by the perpendicular, which is parallel to the sides drawn from the opposing vertices.

The circumcenter of a triangle is the location where the three perpendicular bisectors of the triangle meet.

A(0, 0), B(0, 8), C(6, 0)

Circumcenter , P(x,y)

AP = BP = CP

AP² = BP²

(x - 0 )² + ( y - 8 )² = ( x- 0)² + ( y - 0 )²

x² + y² + 64 - 16y = x² + y²

 64 - 16y = 0

 16y = 64

     y = 4

BP = CP

BP² = CP²

(x - 0)² + ( y- 0 )² = ( x- 6)² + ( y - 0)²

x² + y² = x² 36 - 12x + y²

Answer:

Step-by-step explanation:

So, Vicki wants no left overs whatsoever, which means we have to get all three items to the same number. We first look at 10. We know that 10 will always have a 0 in the one's place, meaning that 8 and 12 have to be multiplied by 5, 10, 15, 20, etc., but they do not need to be multiplied by the same number.

Let's take 8 first. 8 can possibly go up to 40, 80, 120, 160, 200, etc.

Then 12. 12 can possibly go up to 60, 120, 180, 220, 280, etc.

We can see that both numbers have 120 in common, so we shall use that.

We know that we can get 10 to 120 by multiplying 10 by 12, meaning Vicki buys 12 packs of cups.

We know that we can get 12 to 120 by multiplying 12 by 10, meaning Vicki buys 10 packs of plates.

And finally, we know that we can get 8 to 120 by multiplying 8 by 15, meaning Vicki buys 15 packs of utensils.

So, since the question is asking for utensils only, we should say that Vicki buys 15 packs of utensils.

The mean absolute deviation of the given data set is 1.6 (rounded to the nearest tenth).

We have,

In statistics, the mean (also known as the arithmetic mean or average) is a measure of central tendency that represents the sum of a set of numbers divided by the total number of numbers in the set.

To find the mean absolute deviation (MAD), we need to first calculate the mean of the given data set:

mean = (4 + 5 + 7 + 9 + 8) / 5 = 6.6

Next, we calculate the deviation of each data point from the mean:

|4 - 6.6| = 2.6

|5 - 6.6| = 1.6

|7 - 6.6| = 0.4

|9 - 6.6| = 2.4

|8 - 6.6| = 1.4

Then we find the average of these deviations, which gives us the mean absolute deviation:

MAD = (2.6 + 1.6 + 0.4 + 2.4 + 1.4) / 5 = 1.6

Therefore, the mean absolute deviation of the given data set is 1.6 (rounded to the nearest tenth).

It will take the town 21 years 4 months to reach 4600 in population

a rate is a ratio that compares two different quantities which have different units. For example, if we say John types 50 words in a minute, then his rate of typing is 50 words per minute. The word "per" gives a clue that we are dealing with a rate.

initial population = 3000

population increase every year = 2.5% of 3000

which is 2.5/100 x 3000 = 75

let the time taken to reach 4600 be d

increment for d number of years = 75d

Total population after d years is 75d + 3000

so 75d + 3000 = 4600

75d = 4600  - 3000

75d = 1600

d = 1600/75

d = 21.33 years which is 21 years 4 months

To calculate the present value of the coupons, we need to determine the cash flows from the semi-annual coupons and discount them back to the present value using the yield to maturity.

The coupon payment is 5% of the face value, which is USD 10 million. Therefore, the coupon payment per period is (0.05/2) * USD 10 million = USD 250,000.

The bond matures in 20 years, so the total number of coupon periods is 20 * 2 = 40.

To calculate the present value of the coupons, we discount each coupon payment using the yield to maturity of 7% and sum them up.

\(PV = \frac{{\text{{Coupon1}}}}{{(1 + r)^1}} + \frac{{\text{{Coupon2}}}}{{(1 + r)^2}} + \ldots + \frac{{\text{{Coupon40}}}}{{(1 + r)^{40}}}\)

Where r is the yield to maturity, which is 7%.

Using the present value formula, we can calculate the present value of the coupons:

\(PV = \left(\frac{{USD 250,000}}{{(1 + \frac{{0.07}}{{2}})^1}}\right) + \left(\frac{{USD 250,000}}{{(1 + \frac{{0.07}}{{2}})^2}}\right) + \ldots + \left(\frac{{USD 250,000}}{{(1 + \frac{{0.07}}{{2}})^{40}}}\right)\)

Calculating this sum will give us the present value of the coupons.

Answer:

Since the range of a set is the difference between the highest and the lowest value in that set, the range here is:

9 - 3 = 6

The points on the curve y = cos(x/2) + sin(x) where the tangent line is horizontal occur at x = (4n + 1)π, where n is an integer.

To find the points on the curve where the tangent line is horizontal, we need to determine when the derivative dy/dx is equal to zero. Taking the derivative of y = cos(x/2) + sin(x) with respect to x, we get:

dy/dx = -sin(x/2)/2 + cos(x)

Setting dy/dx equal to zero and simplifying, we have:

-sin(x/2)/2 + cos(x) = 0

sin(x/2) = 2cos(x)

Using the identity sin^2(x/2) + cos^2(x/2) = 1, we can rewrite the equation as:

2cos(x) + 2cos(x/2)cos(x/2) = 0

2cos(x) + 2cos^2(x/2) - 1 = 0

2cos^2(x/2) + 2cos(x) - 1 = 0

Solving this equation for cos(x/2), we find two solutions: cos(x/2) = 1/2 and cos(x/2) = -1. The first solution corresponds to the points where the tangent line is horizontal. This occurs when cos(x/2) = 1/2, which implies x/2 = (2nπ ± π/3), where n is an integer.

Therefore, the points on the curve where the tangent line is horizontal are given by x = (4n + 1)π, where n is an integer.

The main answer, incorporating the continuity correction, is P(X < 8.5), where X represents a random variable.

To calculate the probability of X being fewer than 8 (excluding 8) with continuity correction, we can use the normal approximation to the binomial distribution.

Assuming X follows a binomial distribution, we can approximate it with a normal distribution by adjusting the boundaries of the interval. In this case, since we want fewer than 8 (excluding 8), we use the continuity correction and consider the interval as (X < 8.5).

We can then calculate the probability using the cumulative distribution function (CDF) of the normal distribution for X = 8.5. The resulting probability represents the likelihood of observing fewer than 8 (excluding 8) occurrences.

If Charmaine made 8 stacks with her coins and every stack had 6 coins, then the number of coins that she has all together is 48 coins

The number of coins that she has made  = 8 stacks

The number of coins in each stack = 6 coins

To find the number of coins that she has, we have to multiply the number of stack and number of coins in each stack

Then the number of coins that she has all together = The number of coins that she has made × The number of coins in each stack

Substitute the values in the equation

= 8 × 6

= 48 coins

Answer:29.2

Step-by-step explanation:The equation used to add a markup percent to a product is the cost plus the markup percentage multiplied by the cost.

Answer:

$29.20

Step-by-step explanation:

The original price of an item is 100%, so a 60% mark up means that the price will now be 160% of the original price.

160% = 160/100 = 1.6

⇒ 160% of $18.25 = 1.6 × 18.25 = $29.20

The statistics z is -1.878 and the p value is 0.0302

Given,

Number of random sample selected, n = 6967

Number of surveys returned, x = 1331

Estimated proportion of return rate;

p = 1331/6967 = 0.192

Significance level, ∝ = 0.01

z would represent the statistic

We investigate the assertion that the return rate is less than 20%, and the following hypotheses are tested:

Null hypothesis, p₀ ≥ 0.2

Alternative hypothesis, p₀ < 0.2

The statistics, z = (p - p₀) / √(p₀(1 - p₀)/n)

That is,

z = (0.191 - 0.2) / √(0.2(1 - 0.2)/6967) = -1.878

Using the alternative hypothesis and the following probability, we can now get the p value:

p value  = p(z < - 1.878) = 0.0302

We fail to reject the null hypothesis when the p value exceeds the significance level of 0.01 and there is insufficient evidence to support the conclusion that the return rate is less than 20% at 1% of significance.

The total time it will take Montraie to drive from City X to City Y is:

5 hours and 12 minutes

The scale drawing, it would be difficult to determine the distance between City X and City Y.

But since we have the scale drawing, we can use it to find the actual distance between the two cities.

The scale drawing, we see that the distance between City X and City Y is 3 inches.

Using the given scale of 1/4 inch = 13 miles, we can set up a proportion to find the actual distance:

1/4 inch / 13 miles = 3 inches / x miles

Cross-multiplying, we get:

1/4 inch × x miles = 13 miles × 3 inches

Simplifying, we get:

x = 156 miles

So the distance between City X and City Y is 156 miles.

To find the time it will take Montraie to drive from City X to City Y, we can use the formula:

time = distance / speed

Plugging in the values we know, we get:

time = 156 miles / 30 miles per hour

Simplifying, we get:

time = 5.2 hours

To convert this to hours and minutes, we can separate the whole number and the decimal part:

5 hours + 0.2 hours

To convert the decimal part to minutes, we can multiply it by 60:

0.2 hours × 60 minutes per hour = 12 minutes

The angular area of the HST's field of view is 25 square degrees.

The field of view is the extent of the sky that the Hubble Space Telescope (HST) can observe at a given time. It is usually measured in degrees.

To calculate the angular area, we can use the formula for the area of a circle:

Area = π * (angular size/2)^2

Where π is a mathematical constant approximately equal to 3.14, and the angular size is in degrees.

Let's say the angular size of the HST's field of view is 10 degrees.

First, we divide the angular size by 2:

10 degrees / 2 = 5 degrees

Next, we square the result:

5 degrees * 5 degrees = 25 square degrees
