=======================================================

Explanation:

Fractions are a pain to deal with, so whenever possible I recommend you eliminate them. With equations like this, you can multiply both sides by the same number to do so. The question is: which number would that be?

If you pick on the LCD, then you'll be able to clear out the fractions. The LCD of 1/2, 1/3, and 5/6 is 6 since the LCM of the denominators is 6.

Multiply both sides by 6 to get

(1/2)x - 1/3 = 5/6

6*[ (1/2)x - 1/3 ] = 6(5/6)

6*(1/2)x - 6*(1/3) = 6(5/6)

3x - 2 = 5

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

At this point, the fractions are gone. We can now solve like so

3x-2 = 5

3x-2+2 = 5+2 ... adding 2 to both sides

3x = 7

3x/3 = 7/3 .... dividing both sides by 3

x = 7/3

Answer:

x=5/6

Step-by-step explanation:

12x−13=5612x-13=56

Combine 1212 and xx.

x2−13=56x2-13=56

Move all terms not containing xx to the right side of the equation.

Add 1313 to both sides of the equation.

x2=56+13x2=56+13

To write 1313 as a fraction with a common denominator, multiply by 2222.

x2=56+13⋅22x2=56+13⋅22

Write each expression with a common denominator of 66, by multiplying each by an appropriate factor of 11.

Multiply 1313 and 2222.

x2=56+23⋅2x2=56+23⋅2

Multiply 33 by 22.

x2=56+26x2=56+26

Combine the numerators over the common denominator.

x2=5+26x2=5+26

Add 55 and 22.

x2=76x2=76

Multiply both sides of the equation by 22.

2⋅x2=2⋅

The result of an average of more than 100% in a survey of tenants on cleaning chores in shared apartments is likely due to social desirability bias.

The average tenant response of more than 100% in a study about cleaning duties in shared apartments is probably the product of social desirability bias. Social desirability bias occurs when respondents give answers that they think are socially acceptable or desirable, rather than their true opinions or behavior.

In this case, tenants may have overstated their contribution to cleaning the apartment, in order to appear more helpful or responsible, leading to an average percentage higher than 100%.

Since BD bisects Angle ABC, Angle ABD = Angle DBC

Subtract 6 from both sides:

The ideal way to organize electronically the raw data for a study is to use a database management system (DBMS). A DBMS allows the researcher to store, manipulate, and retrieve data in a structured and organized manner. This enables the researcher to easily analyze the data and draw meaningful conclusions from it.

Additionally, a DBMS ensures data accuracy, consistency, and security. Overall, using a DBMS is the most efficient and effective way to manage raw data for a study.
This allows for efficient organization, storage, and retrieval of the data, making it easier to analyze and interpret the results. Additionally, employing proper data cleaning techniques and establishing a clear metadata structure can enhance the overall organization and accessibility of the study's raw data.

Step-by-step explanation:

Given the sets of side lengths of a triangle:

To verify whether each set of side lengths could be the sides of a right triangle, we use the Pythagorean Theorem. Note that the longest side is always taken as the hypotenuse.

In the set of side lengths 10.5 cm, 20.8 cm, 23.3 cm

\(23.3^2=20.8^2+10.5^2\\542.89=432.64+110.25\\542.89=542.89\)

Clearly these satisfies the required theorem and thus are side lengths of a right triangle.

In the set of side lengths 6 cm, 22.9 cm, 20.1 cm

\(22.9^2=20.1^2+6^2\\524.41\neq 440.01\)

Clearly these does not satisfy the required theorem and thus are not side lengths of a right triangle.

Note that based on probabilities,

The expected number of Democrats on the committee is 5.

The expected number of states represented on the committee is 26.

The expected number of states such that both of the state's senators are on the committee is 9.09.

a)  The probability that a randomly chosen senator is a Democrat is 50/100 = 1/2.

So, the expected number of Democrats on a committee of size 10 is

1/2 * 10 = 5.

b) The minimum number of   states that can be represented on a committee of size 10 is 2, and the maximum numberis 50.

The expected number of states representedon the committee is the average of these two values, which is (2 + 50)/  2 = 26.

c)  There are 50 states, and each state has 2 senators. So, there are a total of 100 pairs of senators.

The probability that a randomly chosen pair of senators both belong to the same state is 50/100 * 49/99

= 1/11.

The expected number of states such that both of the state's senators are on the committee is 100 * 1/11 = 9.09.

Find you have to find the mean (average):

3 + 5 + 7 + 9 + 11 = 35

35 / 5 = 7

Mean = 7

The mean absolute deviation is the mean (average) of the distance from the other numbers (absolute means that if the number is negative it turns into a positive):

3 - 7 = 4

5 - 7 = 2

7 - 7 = 0

9 - 7 = 2

11 - 7 = 4

The value of f(5) for the given function is -6.

What is a sequence?

A sequence is an enumerated collection of objects in which repetitions are allowed. Like a set, it contains members (also called elements, or terms).

A heuristic, on the other hand, is an approach to problem-solving that seeks to come up with a workable answer quickly rather than promising an ideal or even accurate solution.

When an algorithmic solution is not viable, useful, or effective, heuristics are frequently applied.

Given that, f(1)=6 and  f(n)=f(n−1)−3 thus we have:

f(2) = f(1) - 3 = 6 - 3 = 3

f(3) = f(2) - 3 = 3 - 3 = 0

f(4) = f(3) - 3 = 0 - 3 = -3

f(5) = f(4) - 3 = -3 - 3 = -6

Hence, the value of f(5) for the given function is -6.

Answer: F. n = s/180 + 2

Step-by-step explanation:

         To find the equation that solves for n, we will isolate the n variable.

Given:

     S = (n - 2) x 180

Divide both sides of the equation by 180:

     \(\frac{S}{180}\) = n - 2

Add 2 to both sides of the equation:

     \(\frac{S}{180}\) + 2 = n

Reflexive property:

    n = \(\frac{S}{180}\) + 2

The interval estimate is:

41.5 - 2.45 ≤ true average time ≤ 41.5 + 2.45

or

38.05 ≤ true average time ≤ 44.95

Inequality notation:

[38.05, 44.95]

The interval estimate that will estimate the true average time that people spend brushing their teeth is [39.05, 43.95] seconds.

Given that the mean time spent brushing teeth from the sample is 41.5 seconds, and the margin of error is 2.45 seconds, we can construct a confidence interval estimate using the formula:

(sample mean) ± (margin of error)

Substituting the given values, we get:

41.5 ± 2.45

Simplifying, we get:

[39.05, 43.95]

Therefore, we can be 95% confident that the true average time that all people spend brushing their teeth falls within this interval.

Step-by-step explanation:

True. Probability of an uncertain outcome is a number between 0 and +1, exclusively.

The probability of an uncertain outcome is a measure of the likelihood that the outcome will occur, and it is always a number between 0 and 1, inclusive. A probability of 0 means that the event is impossible, while a probability of 1 means that the event is certain. Probabilities between 0 and 1 indicate the degree of uncertainty about whether the event will occur or not.

Probabilities cannot be negative or greater than 1, as they represent a proportion of the total possible outcomes. If the probability of an event were negative or greater than 1, it would imply that the event is impossible or certain to occur, respectively, and violate the fundamental laws of probability theory.

In this question we have been given Diego has run 2/3 of a race""s distance. He has run 8 1/2 kilometers.

We need to find the  length of the whole race.

Let the whole race be x.

Since Diego has run 2/3 of a race's distance which is 8 1/2 kilometers. The length of the whole race will be given by an equation:

2/3 × x = 8 1/2

x = (8 1/2) ÷ 2/3

x = (8 1/2) × 3/2

x = 17/2 × 3/2
