Question
The epicenter of an earthquake is the point on Earth's surface directly above the earthquake's origin. A seismograph can be used to determine the distance to the epicenter of an earthquake. Seismographs are needed in three different places to locate an earthquake's epicenter. Find the location of the earthquake's epicenter if it is 2 miles away from A(−2,5), 4 miles away from B(2,3), and 7 miles away from C(−2,−4).

Answers

Answer:

The epicenter is ( - 2, 3)

Step-by-step explanation:

Let the epicenter be E(x, y).

Use the distance formula for each given distance:

AE² = (x + 2)² + (y - 5)² = 2²BE² = (x - 2)² + (y - 3)² = 4²CE² = (x + 2)² + (y + 4)² = 7²

Use the first and third equations, considering both have same term for x, and solve for y:

(y - 5)² - 4 = (y + 4)² - 49y² - 10y + 25 - 4 = y² + 8y + 16 - 4918y = 54y = 3

Substitute y into one of equations and solve for x:

(x + 2)² + (3 - 5)² = 4(x + 2)² + 4 = 4(x + 2)² = 0x + 2 = 0x = - 2

The epicenter is E( - 2, 3)

Answer:

(-2, 3)

Step-by-step explanation:

Given:

A = (-2, 5)  →  2 miles awayB = (2, 3)  →  4 miles awayC = (-2, -4)  →  7 miles away

Model each given point as the center of a circle and the distance the epicenter is away from the point as the circle's radius.

The epicenter's location will be the point of intersection of the three circles.

Equation of a circle

[tex](x-a)^2+(y-b)^2=r^2[/tex]

where (a, b) is the center and r is the radius

Circle A

center = (-2, 5)radius = 2 miles

[tex]\implies (x+2)^2+(y-5)^2=4[/tex]

[tex]\implies x^2+4x+4+y^2-10y+25=4[/tex]

[tex]\implies x^2+4x+y^2-10y+25=0[/tex]

Circle B

center = (2, 3)radius = 4 miles

[tex]\implies (x-2)^2+(y-3)^2=16[/tex]

[tex]\implies x^2-4x+4+y^2-6y+9=16[/tex]

[tex]\implies x^2-4x+y^2-6y-3=0[/tex]

Circle C

center = (-2, -4)radius = 7 miles

[tex]\implies (x+2)^2+(y+4)^2=49[/tex]

[tex]\implies x^2+4x+4+y^2+8y+16=49[/tex]

[tex]\implies x^2+4x+y^2+8y-29=0[/tex]

To find the point of intersection of the three circles, solve simultaneously.

Substitute equation B into equation A to eliminate x² and y²:

[tex]\implies x^2-4x+y^2-6y-3=x^2+4x+y^2-10y+25[/tex]

[tex]\implies -4x-6y-3=4x-10y+25[/tex]

Rearrange to isolate y:

[tex]\implies -6y-3=8x-10y+25[/tex]

[tex]\implies 4y-3=8x+25[/tex]

[tex]\implies 4y=8x+28[/tex]

[tex]\implies y=2x+7[/tex]

Substitute the expression for y into equation C and simplify:

[tex]\implies x^2+4x+(2x+7)^2+8(2x+7)-29=0[/tex]

[tex]\implies x^2+4x+4x^2+28x+49+16x+56-29=0[/tex]

[tex]\implies 5x^2+48x+76=0[/tex]

Substitute the expression for y into equation B and simplify:

[tex]\implies x^2-4x+(2x+7)^2-6(2x+7)-3=0[/tex]

[tex]\implies x^2-4x+4x^2+28x+49-12x-42-3=0[/tex]

[tex]\implies 5x^2+12x+4=0[/tex]

Equate the equations to eliminate 5x² and solve for x:

[tex]\implies 5x^2+48x+76=5x^2+12x+4[/tex]

[tex]\implies 48x+76=12x+4[/tex]

[tex]\implies 36x+76=4[/tex]

[tex]\implies 36x=-72[/tex]

[tex]\implies x=-2[/tex]

Substitute the found value of x into the found expression for y:

[tex]\implies y=2(-2)+7[/tex]

[tex]\implies y=-4+7[/tex]

[tex]\implies y=3[/tex]

Therefore, the point of intersection of the three circles if (-2, 3) and hence the location of the earthquake's epicenter is (-2, 3).

Answers

ANSWER: 39.7%

Explanation:
1. Determine your chain's density first.
Mass / volume equals density.

volume equals water displaced ml = 20 ml
- 15 ml = 5 ml where volume = Volume of Final Level of Water - Initial Level of Water
Mass = 66.7 g

Density is equal to 66.7g/5 ml, or 13.34 g/ml.


2. Next, calculate the chain's density as the weighted average of its component densities.

Divided by the mass of the chain, the formula is: mass of gold, density of gold, mass of other metals, density of other metals.

If x is the weight of gold, then 66.7 - x is the weight of the other metals:

19.3 - 2 + 9.7 . (66.7
66.7
= 13.34
19.32 + 635.66 - 9.72
= 889.778
9.62
254.118
2 = 26.47
Then, there are 26.47 grams of gold in 66.7
grams of chain, which yields a percentage of:
(26.47 / 66.7) × 100 = 39.7%

12. What effect size do you use for non-parametric t-tests?
13. What effect size would you use for chi-square tests?

Answers

The effective sizes for parametric tests, non parametric tests and chi square tests are as detailed below.

How to interpret the size of statistics test?

11) Parametric t-tests are statistical tests that assume the data approximately follows a normal distribution. Now, when trying to check for parametric t-tests, the effective size we use is Cohen's d which is an appropriate effect size for the comparison between two means.

12) Nonparametric t-tests are those statistical tests that don’t assume anything about the distribution followed by the data, and hence are also known as distribution free tests.

In non - parametric t - tests, we calculate effect size by using the formula;

r = z/√N

where;

r is effect size

z is z value

N is Observation number.

13) In the chi-square test, the effect size index (w) is calculated by dividing the chi-square value by the number of scores and taking the square root.

The effective size is considered small if w = 0.10, Considered medium if w = 0.30, and large if w = 0.50.

Two cars start at the same time, but travel in opposite directions. One car's average speed is 80 miles per hour (mph). At the end of 2 hours, the two cars are 220 miles apart. Find the average speed in mph of the other car.

Answers

The speed of an object is the relationship between the distance covered by the object and the time taken. Thus, the average speed of the other car is 30 mph.

The speed of an object is the relationship between the distance covered by the object and the time taken. The expression for speed is given as;

speed = [tex]\frac{distance covered}{time taken}[/tex]

⇒ distance = speed x time taken

In the given question, the distance of the first car after 2 hours can be determined as:

distance = 80 mph x 2 h

              = 160 miles

The distance covered by the first car after 2 hours is 160 miles.

Thus, since the total distance between the two cars after 2 hours is 220 miles, then;

distance covered by the second car = 220 miles - 160 miles

                                                          = 60 miles

The distance covered by the second car is 60 miles.

So that the average speed of the other car is;

speed = [tex]\frac{60}{2}[/tex]

           = 30 mph

The average speed is 30 miles per hour (mph).
