What is 8/9 divide 4

Answers

Answer: 8/9 divided by 4 is 2/9.

Step-by-step explanation: If you want to divide fractions, first you need to find the reciprocal of the second term. The reciprocal is when you swap the numerator and the denominator. The reciprocal of 4 is 1/4. Then, you multiply 8/9 is 1/4. 8 x 1 is 8, and 9 x 4 is 36. The answer is 8/36, which you can simplify into 2/9.

The value of the expression (8/9)÷4 is (8/9)×1/4.

What is PEMDAS rule?

PEMDAS rule states the correct order of simplifying an expression is as follows -: Parenthesis, exponents, multiplications, divisions, additions, and, subtractions.

Given, A fraction 8/9 and it is being divided by 4.

∴ (8/9)÷4.

= (8/9)×1/4.  (think of flipping the divisor to make it a multiplier)

= 32/9

Or

3 whole 5/9.

Make an equation using the butterfly method:

3(6) = 2x

Simplify:

18=2x

Divide both sides by 2:

Answers

Answer:

Sjaoa

The required cross-sectional area in a wireway is 12.8 In squared.

What is the percentage?

The percentage is defined as a ratio expressed as a fraction of 100.

What are Arithmetic operations?

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

+ Addition operation: Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 4 -2 = 2

We have been given an 8"×8"×6' long wireway the conductors can occupy.

Since the NEC permits 20% of the cross-sectional area in a wireway to be occupied by conductors

So the required cross-sectional area in a wireway is

⇒ 20 % of ( 8"×8" )

⇒ 0.20 × (64 )

⇒ 12.8 In squared

Thus, the required cross-sectional area in a wireway is 12.8 In squared.

You are looking at a pair of parallel lines (a and b) and a transversal that crosses them both.

Now that you know what think back to when you learned the relationship between angles formed by a transversal and a set of parallel lines.

You can have same side exterior, same side interior, alternate interior and alternate exterior. Which set of these are these angles?

Remember same side interior and same side exterior angles are supplementary (they have a sum of 180 degrees). Alternate interior and alternate exterior angles are congruent. Knowing this how can an equation be written using the expressions in the image?

Step-by-step explanation:

Answer:

x = 3.4

Step-by-step explanation:

Since these two angles are opposite exterior angles, they are equivalent. that means that 5x - 2/3 = 3 1/3x + 5, from here you should simplify the terms so you have all of x on one side and all of the number on ther other, it should be 1 2/3x = 5 2/3, then all you have to do is divide both sides by 1 2/3 to get x which is 3.4 or 3 2/5

A political scientist wants to estimate the percent of registered voters in Florida who plan to vote for a particular candidate. The political scientist interviews 4000 randomly selected registered voters in Florida and asks who they plan to vote for. 58% say they plan to vote for the candidate. Which of the following statements is true?

a. 58% is a parameter because it describes a population characteristic.
b. 58% is a statistic because it describes a sample characteristic.
c. 58% is a statistic because it describes a population characteristic.
d. 58% is a parameter because it describes a samic characteristic.

Answers

Answer:

b.) 58% is a statistic because it describes a sample characteristic.

Step-by-step explanation:

The randomly selected 4000 voters represents a randomly selected observations from the population of registered voters

Hence, 4000 is a sample.

The percentage of voters who would vote for a particular candidate represents a numerical characteristic derived from the sample drawn.

Recall that, numerical characteristics or values which are calculated from the sample is known as statistic while those derived from the population are called parameter.

Hence, 58% is a statistic as it describes a sample characteristic.

You can use definition of parameter and statistic and then can use them to find what does 58% denotes here.

The true statement is given by:

Option B: 58% is a statistic because it describes a sample characteristic.

What is a population and parameter?

The entire group or system which we are taking in consideration is population. Nothing bigger than it lies there in consideration.

Ex: If we're taking about health problem in a country, then the whole country people form a population.

If we're taking about numbers on a 6 face die, then those 6 numbers on 6 faces form a population.

Those numbers who summarize information about population are called parameter.

What is sample and statistic?

A portion of population taken and analyzed to predict information about population is called sample of that population.

Ex: When someone surveys a group, then he/she surveys a portion and not whole population in general.

Those numbers who summarize information about sample are called statistic.

(Statistic is different than statistics)

Using above definitions to conclude what 58% refers to

Since the 58% is from the 4000 people randomly selected by the political scientist, thus, it is information about sample and thus, is a statistic.

Thus,

The true statement is given by:

Option B: 58% is a statistic because it describes a sample characteristic.
