Answer:

b. Interval estimation

Step-by-step explanation:

There are two types of estimations for each population parameter; the point estimation and confidence interval (CI) estimation.

The point estimation involves the use of sample data to calculate a single value which serve as a best estimate of an unknown population parameter.

The interval estimation is the use of sample data to calculate range of possible values of an unknown population parameter.

Therefore, the correct option is "b"

b. Interval estimation

Answer:

(x-3)^2+(y+1)^2=16

Step-by-step explanation:

The equation of the circle is:

[tex](x - 3)^2 + (y + 1)^2 = 16[/tex]

The equation of a circle with center (h, k) and radius r is given by[tex](x - h)^2 + (y - k)^2 = r^2[/tex], which is a second-order polynomial equation in a single variable. It has at least one solution because it is a second-order polynomial equation, which is guaranteed by the algebraic fundamental theorem. The answer could be simple or complicated.

To complete the equation representing all the points that are 4 units away from the point (3, -1), we need to first recall the equation of a circle, which is:

[tex](x - h)^2 + (y - k)^2 = r^2[/tex]

where (h, k) is the center of the circle and r is the radius.

In this case, the center of the circle is given as (3, -1) and the radius is 4 units since all the points on the circle are 4 units away from the center.

Substituting these values into the equation of a circle, we get:

[tex](x - 3)^2 + (y + 1)^2 = 16[/tex]

This equation represents all the points that are 4 units away from the point (3, -1) and forms a circle with center (3, -1) and radius 4 units.

Answer: 4

Step-by-step explanation:  g(x) = A*cos(bx) + c When you see a function of the form f(x) = A*sin(bx) + c or g(x) = A*cos(bx) + c where A, b and c are constants, its amplitude is equal to A, the coefficient at sine or cosine.

The amplitude of the given function is 4.

The maximum displacement or distance moved by a point on a vibrating body or wave, measured from its equilibrium position, is called its amplitude.

Given is a function, y = 4sin (3x + 2) + 1

The given equation is the form of y = a sin(bx+c) + d, the amplitude of the function is given by the by a,

On comparing the given equation with y = a sin(bx+c) + d, it gives a = 4

Hence, the amplitude of the given function is 4.

The length of each side of the square is, 6 centimeter.

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

We have to given that;

The area of a square is 36 square centimeters.

Now, We know that;

⇒ Area of square = Side²

Let the side of square = x

Hence, We can formulate;

⇒ x² = 36

⇒ x = √ 36

⇒ x = 6 centimeters

A rate is a ratio that compares two different quantities that have different units of measure. A rate is a comparison that provides information such as dollars per hour, feet per second, miles per hour, and dollars per quart, for example. The word “per” usually indicates you are dealing with a rate.

The ratio between the two given quantities is 3:1

What is proportion ?

A proportion is an equation based on the equality of two ratios.

It is to find the ratio of two quantities given as :

5 days to 60 hours

It is to be noted that two quantities can only compared when there units are same therefore first let us make the units same :

we known that :

1 day = 24 hours

that is, 5 days = 5x24 = 120 hours

Now, we can find the ratio :

5 days : 60 hours

120 hours : 60 hours

3 : 1

Therefore, the ratio between the two given quantities is 3:1

Answer:

$10.50 is the tip on a dinner bill.

Step-by-step explanation:

The first step is to round off $67.42. It is closer to 70 than 60, therefore it is 70.

Secondly, 10% of 70 is 7.

5% of 7 is 3.5.

*Notice that 10% and 5% equals 15%.

Add 7 + 3.5 = 10.5 or $10.50

The only thing we can say about the line is that x = 12 is a vertical line.

Remember that the general linear equation is:

a*x + b*y = c

Particularly, if we take b = 0, the dependence on y disappears, and then we get a vertical line.

This is just a vertical line that crosses the x-axis at x = 12. (and never crosses the y-axis).

So the only correct option is the first one.

Step-by-step explanation:

Generally the range for the population mean value with 95% confidence intervals for the first set of data  is mathematically evaluated as follows

Generally the degree of freedom is mathematically evaluated as

From the question we are told the confidence level is  95% , hence the level of significance is    

      [tex]\alpha = (100 - 95 ) \%[/tex]

=>   [tex]\alpha = 0.05[/tex]

Generally from the t distribution table the critical value  of    at  is
