Answer: 5

Step-by-step explanation: because 5x5 is 25, and in the ones place is 5, and 5 is a factor of 25 so it works

Answer: The digits present in the one's place of a number that has a factor of 5 are 0 and 5.

Step-by-step explanation:

The margin of error for the 95% confidence interval used to estimate the population proportion is 0.0680. So, the correct answer is option d.

Calculate the sample proportion:

The formula (p) = x/n, where x is the sample size (163) and n is the number of successes (96), yields the sample proportion.

Therefore, the sample proportion is 96/163 = 0.5896.

Calculate the standard error:

The formula SE(p) yields the sample proportion's standard error = √[p(1-p)/n], where n is the sample size, and p is the sample proportion.

Consequently, the sample proportion's standard error is as follows:

SE(p) = √[0.5896(1-0.5896)/163] = 0.037

Calculate the margin of error:

The margin of error is given by the formula ME = z × SE(p), where SE(p) is the standard error of the sample proportion and z is the z-score corresponding to the desired level of confidence.

The z-score for a 95% confidence interval is 1.96.

As a result, the error margin is:

ME = 1.96 × 0.037 = 0.0680

none of the provided options (a, b, c, d) appear to be accurate or close to the minimum space required.

To determine the minimum space required for a male restroom design with the given plumbing requirements, we need to consider the minimum space required for water closets and lavatories.

The minimum space required for water closets is typically around 30-36 inches per unit, and for lavatories, it is around 24-30 inches per unit.

Since the design requires a minimum of 12 water closets and 13 lavatories, we can estimate the minimum space required as follows:

Minimum space required for water closets = 12 water closets * 30 inches = 360 inches

Minimum space required for lavatories = 13 lavatories * 24 inches = 312 inches

Adding these two values together, we get a total minimum space requirement of 672 inches.

Among the given options, the closest value to 672 inches is option d) 249. However, this value seems significantly lower than the expected minimum space requirement.

The transformation on a line such that a line is obtained which is pependicular to previous line is possible only when it is reflected through y = x axis. This can be understood as,

When line is reflected about x-axis, the x coordinate remain same where as y-coordinate changes in opposite sign with same magnitude. So reflection of line x = 3 about x axis remain same.

Simillarly reflection of line x = 3 about x = 1 remain same as x = 3.

The reflection of line x = 3 about y-axis results n a parallel line passing through x = -3.

So answer is reflection across y = x.

The correct option is option (C) .

Cluster Sampling is a type of probability sampling and other options are non- probability sampling examples .

Sampling :

Sampling is defined as a technique that selects individual members or subsets from a population to help determine characteristics of the population as a whole.

Croach and Housden postulate that a sample is a finite number taken from a large group for testing and analysis, and that the sample can be taken as representative of the group as a whole.

There are two main types of sampling:

i) probability sampling

ii) Non-probability sampling

A) probability sampling:

It is defined as the sampling technique which researchers use a related method to draw probability theory samples from a larger population.

The most important requirement for probabilistic sampling is that everyone in the population has a known equal chance of being selected.

Probability Samples:

1. Stratified Sampling: Stratified sampling is a type of sampling technique that divides the total population into smaller groups or strata to complete the sampling process. Hierarchies are formed based on some common characteristics of demographic data.

2. Cluster Sampling: Cluster sampling is a probabilistic sampling technique in which researchers divide a population into multiple groups (clusters) for research purposes. Researchers then select random groups using simple sampling techniques for data collection and data analysis.

Step-by-step explanation:

The matrix must have pivot columns. Otherwise, the equation Ax = 0 would have a free variable, in which case the columns of A would not span R5. Therefore, the correct answer is C.

A pivot column is a column of the matrix that has a non-zero entry in the pivot position and all entries below the pivot are zero. In row echelon form, every row below a pivot column has a zero in the corresponding position. The pivot columns correspond to the linearly independent columns of the original matrix and the number of pivot columns determines the rank of the matrix.

The rank of a matrix is defined as the number of linearly independent columns or rows in the matrix. If the columns of a matrix span Rn, then the rank of the matrix must be equal to n. This means that the matrix must have n linearly independent columns. To ensure that the columns of A span R5, A must have at least 5 pivot columns. If A had fewer pivot columns, then the equation Ax = 0 would have a non-trivial solution, meaning that the columns of A would not be linearly independent and would not span R5.

Answer:

The answer is y = 7/x -6.

Step-by-step explanation:

A linear function is one where x and y are both to the first power.  Using this knowledge, let's look at the options that we are given.

y = 4x + 9

In the above equation, both x and y are raised to the first power, so we know that this equation is linear.

y = 7/x - 6

In the above equation, y is raised to the first power, but x is not.  Since x is in the denominator of a fraction, it actually has a power of -1, which makes this equation nonlinear.

y = x - 6/7

In the above equation, both x and y are raised to the first power, making the equation linear.

Therefore, the correct choice is y =7/x - 6.

The object would feel a force of approximately 5.35 Newtons if it is at a distance of 0.77 meters from the other charged object.

If the force between two charged objects varies inversely with the square of their distance, then we can use the following formula: F =

\(kQ1Q2 / r^2\) where F is the force, \(Q1\) and \(Q2\) are the charges on the objects, r is the distance between them, and k is a constant of proportionality.

To find the value of k, we can use the given information that when the objects are at a distance of 0.64 meters apart, the force acting on them is 8.2 Newtons. Thus, we have: 8.2 =  \(kQ1Q2 / (0.64)^2\)

To find the force when the objects are 0.77 meters apart, we can rearrange the equation and solve for F: F =  \(kQ1Q2 / (0.77)^2\)

We can then substitute the value of k from the first equation and solve for \(F: F = (8.2 * (0.64)^2) / (0.77)^2 F\) = 5.35 Newtons.

Answer:

C

Step-by-step explanation:

Recall that the standard form for the explicit formula of a geometric sequence is given by:

\(a_n=a\cdot(r)^{n-1}\)

Where a is the initial term, r is the common ratio, and n is the nth term.

Our sequence is 8, 4, 2, 1, and so on.

Hence, our initial term a is 8.

Each subsequent term is half of the previous one. So, our common ratio r is 1/2.

Therefore, by substitution, we acquire:

\(\displaystyle a_n=8\cdot\left(\frac{1}{2}\right)^{n-1}\)

In conclusion, our answer is C.

6 miles is farther than 6 kilometers. One mile is equal to 1.60934 kilometers, so 6 miles is equal to 6 x 1.60934 = 9.65604 kilometers. Therefore, 6 miles is farther than 6 kilometers.

Step-by-step explanation:

The answer is:

Work/explanation:

We can't really compare two things if they have different units.

So we need to convert kilometers to miles first.

1 km is approximately equal to 0.621 miles.

So 6 km would be approximately 3.728 miles.

6 miles is further away than 3.728 miles.

6 km is not as far as 6 miles. And now we know why.

If the composite functions f(g(x)) and g(f(x)) both equal to x, then the function g is the Inverse function of f.

A function that can reverse into another function is known as an inverse function or anti-function. In other words, the inverse of a function "f" will take y to x if any function "f" takes x to y. 

Let us take the Example.

Suppose f(x)= x/4 and g(x)=4x.

Let x=1

then f(g(x))= f(g(1))=f(4)=1

and g(f(x))=g(f(1))=g(1/4)=1

Here, f(g(x))=g(f(x))=1

Therefore , we can say that f(g(x)) and g(f(x)) are inverse of each other.

Answer:

x = 7 and x = \(\frac{21}{8}\)

Step-by-step explanation:

(3)

\(\frac{x+3}{2}\) = 5 ( multiply both sides by 2 to clear the fraction )

x + 3 = 10 ( subtract 3 from both sides )

x = 7

-----------------------------------------------------------

(4)

17 + 5(2x - 9) = - 6x + 10 + 4 ← distribute parenthesis on left side and simplify

17 + 10x - 45 = - 6x + 14

10x - 28 = - 6x + 14 ( add 6x to both sides )

16x - 28 = 14 ( add 28 to both sides )

16x = 42 ( divide both sides by 16 )

x = \(\frac{42}{16}\) = \(\frac{21}{8}\)

We have:

\(a=2x-3\\b=3x-1\)

The domain:

\(2x-3>0\ \wedge\ 3x-1>0\\\\2x-3+3>0+3\ \wedge\ 3x-1+1>0+1\\\\2x>3\ \wedge\ 3x>1\\\\\dfrac{2x}{2}>\dfrac{3}{2}\ \wedge\ \dfrac{3x}{3}>\dfrac{1}{3}\\\\x>1.5\ \wedge\ x>\dfrac{1}{3}\Rightarrow\boxed{x>1.5}\)

Substitute:

\(A=(2x-3)(3x-1)\)

use FOIL: (a + b)(c + d) = ac + ad + bc + bd

\(A= (2x)(3x)+(2x)(-1)+(-3)(3x)+(-3)(-1)\\\\A=6x^2-2x-9x+3\)

combine like terms

\(A= 6x^2+(-2x-9x)+3\\\\A=6x^2-11x+3\)

Answer:

6x² - 11x + 3

Step-by-step explanation:

To find the area of a rectangle, we multiply the length by the width.

A = l • w

length: 2x-3

width: 3x-1

A = (2x-3) • (3x-1)

To multiply these two binomials, we must FOIL (first | outer | inner | last) them.

F: 2x • 3x = 6x²

O: 2x • -1 = -2x

I: -3 • 3x = -9x

L: -3 • -1 = 3

Combine the terms.

6x² - 2x - 9x + 3

Combine like terms.

6x² - 11x + 3
