The equation of the circle is given by (C) (x-3)² + (y + 4)² = 9

All points in a plane that are at a specific distance from a specific point, the center, form a circle. In other words, it is the curve that a moving point in a plane draws to keep its distance from a specific point constant. The radius of a circle is the separation between any point on the circle and its center.

The equation of the circle in the general form is given by the

(x-a)²+(y-b)²=r²

Where (a,b) is the co-ordinates of the center of the circle and the radius is r.

Now the center of the circle is given at (3,-4) and the radius is r.

We know that the general equation of a circle is  \({\displaystyle (x-a)^{2}+(y-b)^{2}=r^{2}}\)

Substituting the values in the equation we get:

(x-3)²+(y-(-4))²=(3)²

or, (x-3)²+(y+4)²=9

Hence the equation of the circle is (x-3)² + (y + 4)² = 9.

The test statistic for Norah's test is \(t = -2\)

Step-by-step explanation:

Norah is in charge of a quality control test that involves measuring the amounts in a sample of bottles to see if the sample mean amount is significantly different than 500 ml.

This means that at the null hypothesis we test if the sample mean is 500 ml, that is:

\(H_0: \mu = 500\)

At the alternate hypothesis, we test if it is differente than 500 ml, that is:

\(H_a: \mu \neq 500\)

The test statistic is:

\(t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}\)

In which X is the sample mean, \(\mu\) is the value tested at the null hypothesis, s is the standard deviation of the sample and n is the size of the sample.

500 is tested at the null hypothesis:

This means that \(\mu = 500\)

She takes a random sample of 16 bottles and finds a mean amount of 497ml, and a sample standard deviation of 6ml.

This means that \(n = 16, X = 497, s = 6\)

Calculate the test statistic for Norah's test.

\(t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}\)

\(t = \frac{497 - 500}{\frac{6}{\sqrt{16}}}\)

\(t = -2\)

The test statistic for Norah's test is \(t = -2\)

Answer:

Step-by-step explanation:

The equivalent between sets is determined by the number of elements. If two sets have the same number of elements, then they are equivalent sets.

In this case, a year has 12 months, and the US has 50 states. So, one month is not equal to 1 state because they have different natures and they represent a different proportion. A month represents 1/12 of a year and a state represents 1/50 of the total number of states.

Answer:

Step-by-step explanation:

This problem is on exponential decay

we know that the expression for exponential formula is

\(y = ab^x.\)

where

a = the amount before measuring growth or decay

= 41,014

r = decay rate = 1.5%= 0.015

x = number of time intervals that have passed= 19years

since this problem is on decay we are going to replace "b" with (1-r),

hence the formula becomes

\(y = a(1-r)^x.\)

\(y=41014(1-0.23)^1^9 \\\\y=41014(0.985)^1^9 \\\\y=41014(0.985)^1^9\)

\(y=41014(0.985)^1^9\\\\y=41014*0.750392\\\\y= 30776.57\)

The approximate number of customers that visit the business in 19 years

the expression would be used as follows:

Number of boxes of donuts (N) = 6 x Number of donuts (D)

Ling bought 108 boxes of donuts.

This expression is a mathematical equation that uses multiplication to calculate the number of boxes of donuts Ling bought.

Equations are used to solve problems involving unknowns, such as how much a person owes for groceries or how many people are required to complete a certain task.

The expression that would show how many boxes of donuts Ling bought is:

Number of boxes of donuts (N) = 6 x Number of donuts (D)

In this expression, N represents the number of boxes of donuts Ling bought and D represents the number of donuts. This expression can be used to calculate the number of boxes of donuts Ling bought when the number of donuts is known.

For example, if Ling bought 18 donuts, the expression would be used as follows:

Number of boxes of donuts (N) = 6 x Number of donuts (D)

N = 6 x 18

N = 108

Therefore, Ling bought 108 boxes of donuts.

This expression is a mathematical equation that uses multiplication to calculate the number of boxes of donuts Ling bought. The expression can be used whenever the number of donuts is known and can be used to calculate the number of boxes of donuts Ling bought.

The triangles that translate to triangle X are A and F.

Triangle ABC is translated to triangle A'B'C', 5 square(s) to the right and 4 square(s) down.

Triangles can be translated by moving each of their vertices a certain distance in a certain direction. The distance and direction of the translation can be described using vector notation.

For example, a translation of a triangle by the vector <a, b> would move each vertex of the triangle a units to the right and b units up. The resulting translated triangle would have the same shape and size as the original triangle, but would be located in a different position in the plane.

The amount of time he spent on the bicycle is; 2.5 hours

The formula that shows the relationship between distance, speed and time is;

distance = velocity * time  

Let W = walking time

B = bicycling time

Thus, from the given data we have;

86 = 4W + 32B      

W + B = 4    

W = 4 - B  substitute 6-B for W in 86 = 4W + 32B to get;

86 = 4(4 - B) + 32B

86 = 16 - 4B + 32B

86 = 16 + 28B

70 = 28B

B = 70/28

B = 2.5 hours on the bicycle

W = 4 - 2.5= 1.5 hours walking

Testing the hypothesis, it is found that the appropriate test statistic is z = 0.54.

At the null hypothesis, it is tested if the proportion of women physics majors in your college is the same as the national average of 19%, that is:

\(H_0: p = 0.19\)

At the alternative hypothesis, it is tested if the proportion is different, that is:

\(H_1: p \neq 0.19\)

The test statistic is given by:

\(z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}\)

In which:

For this problem, the parameters are:

\(p = 0.19, n = 50, \overline{p} = \frac{11}{50} = 0.22\)

Hence, the value of the test statistic is:

\(z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}\)

\(z = \frac{0.22 - 0.19}{\sqrt{\frac{0.19(0.81)}{50}}}\)

\(z = 0.54\)

The x-intercept of the function is (-1/3, 0) and (5, 0)

Given is a graph of a parabola having equation y = -3x²+14x+5, we need to find the x-intercept of the graph,

So to find the x-intercept put y = 0,

Therefore,

-3x²+14x+5 = 0

-3x²+15x-x+5 = 0

-3x(x-5)-1(x-5) = 0

(-3x-1)(x-5) = 0

Therefore,

x = -1/3 and x = 5

Hence the x-intercept of the function is (-1/3, 0) and (5, 0)
