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.

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

The period for which the force acts on the body is  0.6 seconds.

Momentum is the result of a particle's mass and velocity. Being a vector quantity, momentum possesses both magnitude and direction. According to Isaac Newton's second equation of motion, the force acting on the particle equals the time rate of change of momentum.

Given the force applied is 4600 N

F = 4600 N

and change in momentum = Δm = 2760 kg m/s

force is given by a change in momentum to the change in time

F = Δm/Δt

Δt = Δm/F

Δt = 2760/4600

Δt = 0.6 seconds

Hence the change in time is 0.6 seconds.

The probability of getting omeone is  25.3%

Find the probability of getting omeone in the 18-21 age bracket or omeone who repond?

Define the two events

A = someone is in the 18-21 age bracket

B = the person does not respond

Based on the table, we have

n(A) = number of people in set A = 76

n(B) = 31

n(A and B) = 11

So,

n(A or B) = n(A) + n(B) - n(A and B)

n(A or B) = 76+31-11

n(A or B) = 96

We have 96 people in the age 18-21 bracket, they didn't respond, or both.

Answer:

x = 67.5 degrees

Step-by-step explanation:

this is an octagon which has 8 sides

the sum of all interior angles can be found by taking the number of sides, reducing it by 2, and then multiplying by 180

(8-2)*180 = 6(180) = 1080

the 1080° must be split equally among all 8 angles because it is a 'regular' polygon

1080/8 = 135

however, 'x' represents half of each regular angle so it is 67.5 degrees

A linear growth function has a positive constant slope, whereas an exponential growth function has a positive rising slope.

Explanation and response: Exponents are not permitted in a linear equation. Because the link between the two variables does not vary at a constant pace, the exponents in an equation generate a nonlinear graph. Linear functions have a constant rate of change per unit interval. Over equal intervals, an exponential function changes by a similar ratio.

The exponential function is another sort of nonlinear function.A nonlinear function in which the independent variable equals the function’s exponent, as in… The independent variable in these functions is an exponent in the equation. Exponential functions are shown as straight lines on semilog paper. Semi-log paper contains two axes: one arithmetic and one logarithmic. The exponential constant in the equation is given by the slope of the line (m).

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.

4. Divide the maximum acceleration response of the building by the peak ground acceleration of the seismic hazard to obtain the seismic response coefficient.

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 statement that accurately describes unimodal distribution is

" A distribution in which one value is more frequent than other values"

What is unimodal distribution ?

One distinct peak or most frequent value characterises a distribution as unimodal. The values start out climbing, reaching a single high, and then starting to fall. The "mode" in "unimodal" refers to the local maximum on a chart, not the most frequent value in a data set (although they are closely related).

In a graph, one peak will correspond to one mode (one common number), therefore conceptually they are the same thing. There is no list of numbers to go to when attempting to determine if a graph represents a unimodal distribution or not.

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

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