Answer:

7^3

Step-by-step explanation:

since seven is being multiplied by itself 3 times, it is being cubed. So it needs to be raised to the third power.

hope this helps!!! :3

Answer: (-7)(-7)(-7) is equal to -7^3 (just imagine that the three is on the top right outer corner of the 7)

Step-by-step explanation:

A power is when you multiply a number by itself a certain number of times, in this case, we are multiplying the number 7 by itself 3 times. Every time it is multiplied by its self, the power of that number goes up (if you are using a power of one for any number, it will stay the same). Here is an example:

-7 to the first power is just -7.

-7 to the second power, or squared is just (-7)(-7) or (-7) x (-7).

-7 to the third power, or cubed, is just (-7)(-7)(-7) or (-7) x (-7) x (-7).

The mean of this sampling distribution is 70.9, which is less than the value of the population median of  73, therefore, the sample median is a biased estimator of the population median.

The median is the value separating the higher half from the lower half of a data sample, a population, or a probability distribution. For a data set, it may be thought of as "the middle" value.

A statistic used to estimate a parameter is an unbiased estimator if the mean of its sampling distribution is equal to the value of the parameter being estimated.

We obtained the following data from part (a) of this problem,

Sample 1: 64, 65, 73, and median is 65.

Sample 2: 64, 65, 74, and median is 65.

Sample 3: 64, 65, 76, and median is 65.

Sample 4: 64, 73, 74, and median is 73.

Sample 5: 64, 73, 76, and median is 73.

Sample 6: 64, 74, 76, and median is 74.

Sample 7: 65, 73, 74, and median is 73.

Sample 8: 65, 73, 76, and median is 73.

Sample 9: 65, 74, 76, and median is 74.

Sample 10: 73, 74, 76, and median is 74.

Let us calculate the mean of this sampling distribution,

μ(median) = ( 65+65+65+73+73+73+73+74+74+74)/10

μ(median) = 709/10

μ(median) = 70.9

The mean of the sampling distribution is found to be equal to 70.9.

(b) 70.9, which is less than the value of the population median of

73, therefore, the sample median is a biased estimator of the population median.

The function y = 5 + 2x represents a linear function.

Given that point T is the center of dilation, we know that the length of line segments TX' and TY' are proportional to the length of line segments TX and TY, respectively.

We can express this as:

TX' = k * TX

TY' = k * TY

where k is the scale factor.

We are given the lengths of TX' and TY':

TX' = 6

TY' = 9

So, we can solve for k:

9 / k = 6

k = 9 / 6 = 3 / 2

Now that we know the value of k, we can find TY:

TY = TY' / k = 9 / (3 / 2) = 6 * (3 / 2) = 9

Next, we are given the length of XX':

XX' = 2

And using the dilation formula, we can find XX:

XX = XX' / k = 2 / (3 / 2) = 2 * (2 / 3)

Finally, we can find TX by using the Pythagorean theorem:

TX^2 = TY^2 + XX^2

TX^2 = 9^2 + (2 * (2 / 3))^2

TX^2 = 81 + (4 / 3)^2

TX^2 = 81 + 16 / 9

TX^2 = 81 + 16 / 9

TX = √(81 + 16 / 9) = √(81 + 16 * 9 / 9) = √(81 + 16) = √97

So, TY = 9 and TX = √97. Therefore, YT = TY - TY' = 9 - 9 = 0.

TX' = k * TX

Now that we know the value of k, we can find TY:

TY = TY' / k = 9 / (3 / 2) = 6 * (3 / 2) = 9

XX' = 2

XX = XX' / k = 2 / (3 / 2) = 2 * (2 / 3)

TX^2 = TY^2 + XX^2

TX^2 = 9^2 + (2 * (2 / 3))^2

TX^2 = 81 + (4 / 3)^2

TX^2 = 81 + 16 / 9

TX^2 = 81 + 16 / 9

TX = √(81 + 16 / 9) = √(81 + 16 * 9 / 9) = √(81 + 16) = √97

So, TY = 9 and TX = √97. Therefore, YT = TY - TY' = 9 - 9 = 0.

The possible values of two consecutive even integers, of which the sum of their squares is 1684, are 28 and 30 for positive integers, while for negative integers, they are  -28 and -30.

The difference between two consecutive even integers is 2.

Let the integers be a and (a+2). Then,

a² + (a + 2)² = 1684

a² + a² + 4a + 4 = 1684

2a² + 4a - 1680 = 0

a² + 2a -840 = 0

Hence, we get a quadratic equation.

There are three methods of solving a quadratic equations: by factoring, completing the square, and by using the abc formula.

Use the factoring method:

a² + 2a -840 = (a - 28) (a + 30)

a = 28  and a = -30

Hence, if the integers are positive, they are: 28 and 30.

If the integers are negative, they are -28 and -30.

 A perpendicular bisector is a line segment, ray, or line that goes through the middle of a given line segment and crosses it at a 90° angle.

A line, ray, or line segment is a perpendicular bisector if it divides another line segment in half proportionately and makes a right angle (90o) with it at its halfway.

In other words, the perpendicular bisector serves as both a perpendicular line to the line segment and a bisector, cutting it in half.

Answer:

The seismic coefficient represents the maximum horizontal equivalent acceleration expected in a failure wedge in slip potential and is obtained by averaging the horizontal forces in the deformable sliding mass, according to the equation: kmax=¯ah.

It is calculated by dividing the maximum acceleration response of a building by the peak ground acceleration of the underlying seismic hazard.

To calculate the seismic response coefficient, the following steps should be followed:

1. Identify the seismic hazard in the area. This can be done by consulting geological surveys and geological maps.

2. Calculate the peak ground acceleration of the seismic hazard. This can be done using the various seismic hazard assessment techniques such as the probabilistic seismic hazard analysis (PSHA) method.

3. Determine the maximum acceleration response of the building. This can be done by performing a dynamic analysis of the building using a computer simulation program or a hand calculation.

The nature of the roots of a quadratic equation depends on the value of the discriminant, which is given by b^2 - 4ac, where a, b, and c are coefficients in the equation ax^2 + bx + c = 0. If the discriminant is positive, the roots of the equation will be real and distinct, and their sign will depend on the sign of the coefficients a, b, and c. If p, q, and r are positive, the value of the discriminant (q^2 - 4pr) will be positive, and the roots of the equation px^2 + qx + r = 0 will be real and distinct, but their sign cannot be determined just based on the values of p, q, and r alone.

The limit of f(s) as s approaches 6 does not exist because the function has two different values for s approaching 6 from the left and from the right.

A limit is a concept in mathematics that deals with finding the value that a function approaches as the independent variable approaches a certain value.

We need to consider two different cases, as the function f(s) has different definitions for s less than or equal to 6 and s greater than 6.

For s less than or equal to 6, the function f(s) is defined as

As s approaches 6, the value of f(s) will approach

For s greater than 6, the function f(s) is defined as

The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in.

The range is the set of outputs of a relation or function. In other words, it's the set of possible y values. Recall that ordered pairs are of the form (x,y) so the y coordinate is listed after the x. The output is listed after the input.

Given data ,

Let the function be represented as f ( x )
