The option which is not a factor of the cubic equation is (x+4)

The algebraic equations having variables with power 3 are referred to as cubic equations. A generalized form of a cubic equation is ax³+ bx²+ cx + d = 0.

Given here: The cubic function f(x)=x³-12x²+44x-48

Clearly in the options the list of factors are -4,6,2,4

Checking for all 4 options we get

f(-4)=-4³-12×4²+44×(-4)-48

     =-64-192-176-48≠0

f(6)=6³-12×6²+44×(6)-48

    =216-12×36+264-48

    =0

f(2)=2³-12×4+44×2-48

    =8-48+88-48

    =0

The total distance traveled for KLM is 61 meters.

To solve KLM, we need to find the total distance traveled by each segment and then add them up.

Given:

k = 12

l = 9m

m = 20m

We know that "m" is a unit of distance, so we don't need to convert it.

Distance traveled for segment K = k = 12

Distance traveled for segment L = l = 9m

Distance traveled for segment M = m + m = 20m + 20m = 40m

Total distance traveled = K + L + M

= 12 + 9 + 40

= 61 meters.

Therefore, the total distance traveled for KLM is 61 meters.

The average power that Sam applies to move the package from the bottom of the ramp to the top of the ramp is 180 W.

To find the average power that Sam applies to the package to move it from the bottom of the ramp to the top of the ramp, we need to first calculate the work done by Sam on the package and the time taken to do so.

Work done (W) = Force (F) × distance (d)

Time taken (t) = Distance (d) / Speed (v)

Where

,F = 90 N (force required to move the package

)Distance (d) = 6 m (length of the ramp)

Speed (v) = 2 m/s (constant speed at which the package is moved up the ramp)

So, work done,

W = F × d

= 90 N × 6 m

= 540 J

And, time taken,

t = d / v

= 6 m / 2 m/s

= 3 s

Therefore, the average power (P) that Sam applies to the package to move it from the bottom of the ramp to the top of the ramp is given by,

P = W / t

= 540 J / 3 s

= 180 W

Hence, the average power that Sam applies to the package to move it from the bottom of the ramp to the top of the ramp is 180 W.

Sam needs to push a 90.0 kg package up a frictionless ramp that is 6 m long and speed  2 m/s. Sam pushes with a force that is parallel to the incline. what is the average power that sam applies to the package to move the package from the bottom of the ramp to the top of the ramp?

We can say that the functions \(f(x), g(x),\) and\(h(x)\)all increase as x increases, but the rate of increase for h(x) is the fastest, followed by \(g(x),\)and then f(x).

The functions \(f(x) = x, g(x) = xe^x\), and\(h(x) = x^2e^x\) are all defined on the real line.

The function f(x) = x is a linear function with a slope of 1 and passes through the origin. It increases at a constant rate as x increases.

The function g(x) = \(xe^x\)is a product of x and\(e^x,\) where e is the mathematical constant approximately equal to 2.718. This function grows faster than f(x) as x increases because the exponential factor dominates the linear factor.

The function h(x) = \(x^2e^x\) is a product of \(x^2\)and \(e^x\). This function grows even faster than g(x) as x increases because the quadratic factor dominates the linear and exponential factors.

Thus, we can say that the functions \(f(x), g(x),\) and\(h(x)\)all increase as x increases, but the rate of increase for h(x) is the fastest, followed by \(g(x),\)and then f(x).

a. i. There are 27,040,000 different passwords are possible if repetition of digits and letters is allowed and passwords are not case sensitive  (so 123AB is the same as 123aB)

ii. There will be 99,532,800  different passwords are possible if repetition of digits and letters is not allowed and the passwords are case-sensitive

b. i. The probability that all 4 randomly selected students were math majors is  0.520

ii. There are 4,725 different pairs of math majors that could be chosen for the committee.

a. i) There are 10 choices for each of the first 3 digits, and 26 choices for each of the last 2 letters. Since the password is not case sensitive, we can choose either uppercase or lowercase letters, so there are 26 + 26 = 52 choices in total for each letter. Therefore, the total number of different passwords is:

10 x 10 x 10 x 52 x 52 = 27,040,000

ii) There are 10 choices for the first digit, 9 choices for the second digit (since we can't repeat the first digit), 8 choices for the third digit (since we can't repeat the first two digits), and 52 choices for the first letter. For the second letter, there are 51 choices left (since we can't repeat the first letter), but we need to distinguish between uppercase and lowercase letters, so there are 52 x 51 = 2,652 choices for the two letters in total. Therefore, the total number of different passwords is:

10 x 9 x 8 x 52 x 2,652 = 99,532,800

b) i) The total number of ways to select a 4-student committee from 20 students is:

20 choose 4 = 4,845

The number of ways to select a committee consisting of 4 math majors is:

10 choose 4 = 2,520

Therefore, the probability that all 4 randomly selected students were math majors is:

2,520 / 4,845 = 0.520

ii) The number of ways to select a 4-student committee with exactly two math majors is:

(10 choose 2) x (10 choose 2) x (15 choose 0) = 4,725

(We choose 2 math majors from 10, and 2 non-math majors from 15, since there are 5 biology majors and 5 music majors to choose from.)

If a logical vector z has at least one entry TRUE, the function all(!z) will always be false.

If a logical vector contains only TRUE items, the all() method returns FALSE; otherwise, it returns TRUE.

The any() function, on the other hand, gives a result of TRUE if a logical vector has at least one element that is TRUE and FALSE otherwise.

any(z) will always be TRUE if z contains at least one TRUE element since there is at least one TRUE element. On the other hand, depending on whether all of the components of z are TRUE, all(z) may or may not be TRUE.

any(!z) will always return FALSE since if z has at least one TRUE element, then!z must include at least one FALSE element.

Additionally, all(!z) will always return FALSE if any element is FALSE since if z has at least one TRUE element, then!z must include at least one FALSE element.

In order to achieve a margin of error of 0.5 hours, the researcher would need a sample size of 26 from each population, i.e., a total of 52 high school students To determine the required sample size for a desired margin of error in estimating the difference between the means of two populations, we can use the formula:

n = (Z * σ / E)^2

where:

- n is the required sample size,

- Z is the z-score corresponding to the desired confidence level,

- σ is the estimated standard deviation of the population, and

- E is the desired margin of error.

In this case, we are given a 95% confidence interval with a margin of error of 0.5 hours. The conservative value for the degrees of freedom is 1.01, corresponding to the t-distribution.

To calculate the required sample size, we need the estimated standard deviation of the population. Since the standard deviations are not provided for each population separately, we can use the average of the two standard deviations as an estimate. Therefore, σ = (3 + 2) / 2 = 2.5 hours.

Plugging in the values into the formula, we have:

n = (1.01 * 2.5 / 0.5)^2

n = 5.05^2

n ≈ 25.5025

Since the sample size needs to be a whole number, we should round up the result to the nearest integer. Therefore, the required sample size is 26.

Hence, in order to achieve a margin of error of 0.5 hours, the researcher would need a sample size of 26 from each population, i.e., a total of 52 high school students (26 from the suburban district and 26 from the city district).

y = 18

Hint

If we define x to be the value of one of the factors, since 1 + 2 + 3 + 4 + 5 ... + 10 = 11(5) = 55, the value of the other factor has to be 55-x.

Step-by-step explanation:

The likelihood that a researcher will obtain the same result using the same measures the next time he or she tests a hypothesis is Reliability.

In statistics and psychometrics, reliability is the overall consistency of measurements. Measurements are more reliable when similar results are obtained under the same conditions. Reliable results are accurate, reproducible, and consistent from test event to test event. In other words, if the testing process were repeated on a group of test takers, they would yield essentially the same results. Various types of confidence factors with values ​​ranging from 0.00 (large error) to 1.00 (no error) are commonly used to indicate the amount of error in the assessment.

Examples: include measurements of a person's height and weight. Very reliable in many cases. There are several general classes of reliability estimates: 71.

Retest reliability measures the consistency of test results from one test to the next. Measurements are collected by a single rater using the same method or equipment and the same test conditions. This includes intra-rater reliability.

Inter-method reliability measures how consistent test results are when there is variation in the method or instrumentation used. This means that inter-rater reliability can be ruled out.

The amount invested in AAA - bonds is $5353, amount invested in

A - bonds is $1681 and amount invested in B - bonds is $3369. The solution has been obtained by using matrices.

What are matrices?

The term "matrix of order m by n," sometimes known as "m × n matrix," refers to a rectangular array of m × n numbers (real or complex), organised into m rows and n columns.

Such a range is bounded by [ ] or ( ).

We are given equations as

x + y + z = $10300

0.045x + 0.05y + 0.09z = $620

2y − z = 0

From this, we get the matrix as

\(\left[\begin{array}{ccc}1&1&1\\0.045&0.05&0.09\\0&2&-1\end{array}\right] \left[\begin{array}{ccc}x\\y\\z\end{array}\right] = \left[\begin{array}{ccc}10300\\620\\0\end{array}\right]\)

This shows that AX = B

X = A⁻¹B

\(\left[\begin{array}{ccc}x\\y\\z\end{array}\right]\) \(= \left[\begin{array}{ccc}2.42&-31.57&-0.42\\-0.47&10.52&0.47\\-0.94&21.05&-0.05\end{array}\right]\)     \(\left[\begin{array}{ccc}10300\\620\\0\end{array}\right]\)

The angle of elevation from the base to the top of the mountain is approximately 26.57 degrees.

To find the angle of elevation from the base to the top of the mountain, we need to use the tangent function. The tangent of an angle is equal to the opposite side (vertical height) divided by the adjacent side (distance from the base to the top).
So, tangent (angle) = vertical height / distance

Plugging in the values given in the question:
tangent (angle) = 1100 / 2200
Simplifying:
tangent (angle) = 1/2
Now we need to find the angle whose tangent is 1/2. We can do this by using the inverse tangent function (also known as arctangent or tan^-1).
So, angle = tan^-1 (1/2)
