3n -4 =11 i need to show solving steps

Answers

Answer 1
3n-4=11
+4 +4
3n=15 divide both by 3
n=5
Answer 2

Answer:

n=5

Step-by-step explanation:

To solve this, find the value of n to one side of the equation.

N is a variable.

Variable is a quantity that can assume any of a set of values.

3n-4=11

First, you add by 4 from both sides.

[tex]\sf{3n-4+4=11+4}[/tex]

Solve.

[tex]\sf{11+4=15}[/tex]

[tex]\sf{3n=15}[/tex]

Then, you divide by 3 from both sides.

[tex]\sf{\dfrac{3n}{3}=\dfrac{15}{3} }[/tex]

Solve.

15/3=5

[tex]\Rightarrow \boxed{\sf{n=5}}[/tex]

As a result, the solution is n=5, which is our answer.

I hope this helps, let me know if you have any questions.

A graph is proportional if it has a straight line that goes through the origin.

true


false

Answers

It is false that a graph is proportional if it has a straight line that goes through the origin.

Given a statement that a  graph is proportional if it has a straight line that goes through the origin.

We are required to find whether the statement is true or false.

A proportional relationship graph between two variables is basically a relationship where the ratio between the two variables is always the same.

The statement that a graph is proportional if it has a straight line that goes through the origin because there can be many graphs which can pass through origin. For proportionality along with passing through origin, a constant rate should also be there.

Hence it is false that a graph is proportional if it has a straight line that goes through the origin.

Irrational numbers: √13Rational numbers: 4 1/3 and 8What is termed as Rational and Irrational Numbers?

Irrational numbers are real numbers that can't be expressed as a fraction, p/q, where p and q are integers.

The numerator q does not equal zero (q≠ 0). Furthermore, an irrational number's decimal expansion is neither terminating nor repeating.Irrational numbers are all square roots that are not a perfect square. {√2, √3, √5, √8}Some well-known irrational numbers include Euler's number, the Golden ratio, and Pi. {e, ∅, ㄫ}Any prime number's square root is an irrational number.

Thus, √13 is irrational number.

Rational numbers are written in the form p/q, where p and q can be any integer as well as q≠ 0 respectively. Natural numbers, whole numbers, integers, fractions of integers, and decimals are all examples of rational numbers.Integers such as -2, 0, 3, and so on are rational numbers.Rational numbers are fractions with integer numerators and denominators, such as 3/7, -6/5, and so on.

The sum of three numbers is 16. The third is 4 more than 5 times the second. 4 times the first is 9 more than 8 times the second. Find the numbers

Answers

The numbers in which is "the sum of three numbers is 16 are 4.6875, 1.21875 and 10.09375 respectively.

How to find unknown number using algebra?

Let

The first number = aThe second number = bThe third number = cTotal sum = 16

c = 5b + 4

4a = 8b + 9

From the second equation

a = (8b + 9) / 4

16 = a + b + c

16 = (8b + 9) / 4 + b + (5b + 4)

16 = (8b + 9) / 4 + b + 5b + 4

16 = (8b + 9)/4 + 6b + 4

16 - 4 = (8b + 9)/4 + 6b

12 = (8b + 9 + 24b) / 4

cross product

12 × 4 = 8b + 9 + 24b

48 = 32b + 9

48 - 9 = 32b

39 = 32b

b = 39/32

b = 1.21875

Recall,

c = 5b + 4

c = 5(1.21875) + 4

c = 6.09375 + 4

c = 10.09375

Also,

16 = a + b + c

16 = a + 1.21875+ 10.09375

16 = a + 11.3125

16 - 11.3125 = a

a = 4.6875

So therefore, the three numbers represented by the expression are 4.6875, 1.21875 and 10.09375 respectively.

What is algebraic representation?

A module for an associative algebra is that algebraic representation in abstract algebra. In this case, an associative algebra is a ring, which need not be unitary.

If the algebra is not unitary, it can be made to be so using a standard method (see the adjoint functors page); there is no fundamental difference between the algebraic representations and the modules for the resulting unitary ring, in which the identity acts through the identity mapping.

Point A in both triangles are same

Most exhibition shows open in the morning and close in the late evening.

Assume that the arrival times follow a normal distribution.

minutes after doors open

(b) At what time after the doors open will only 14% of the people who are coming to the Saturday show have arrived? (Round your answer to the nearest number of minutes.)
minutes after doors open

Answers

Using the normal distribution:

(a) 309 minutes after the doors open

(b) 172 minutes after the doors open.

In a normal distribution with mean μ and standard deviation σ, the z-score of a measure X is given by:

Z = ( X - μ ) / σ

It counts the number of standard deviations the value deviates from the mean.

We look at the z-score table after determining the z-score to determine the p-value, which is the percentile of X.

Now, we have

Mean of 3 hours and 48 minutes, therefore:

μ = 3(60) + 48 = 228 minutes

The standard deviation, σ = 52 minutes

(a) The doors open with 94% of the people who come to the Saturday show.

We look 94%, or 0.94, up in the cells of a z table.  The closest we can get to this value is 0.9406, which corresponds to a z score of 1.56:

Z = ( X - μ ) / σ

1.56 = ( X - 228 ) / 52

1.56 × 52 = X - 228

81.12 = X - 228

X = 309.12

X = 309 minutes

(b) We look 14%, or 0.14, up in the cells of a z table.  The closest we can get to this value is 0.1401, which corresponds to a z score of - 1.08:

- 1.08 = ( X - 228 )/ 52

- 1.08 × 52 = X - 228

- 56.16 = X - 228

X = 228 - 56.16

X = 171.84

Answer:

Step-by-step explanation:

Find the missing angles

Angle b and 118 are vertical angles and vertical angles are equal

b = 118

Angle c and 118 form a straight line which add to 180

c+118 = 180

c = 180-118

c = 62

c and 118 degrees should add up to 180 degrees:

180 - 118 = 62 degrees for c

b and the unknown angle should also add up to 180 and from the line intersections are the same as c and 118.

b = 118

suppose cattle in a large herd have a mean weight of 1428lbs and a standard deviation of 119lbs. what is the probability that the mean weight of the sample of cows would differ from the population mean by less than 11lbs if 49 cows are sampled at random from the herd? round your answer to four decimal places.

Answers

The probability that the population mean is less than 11lbs is 0

How to determine the probability?

From the question, the given parameters about the distribution are

Mean value = 1428Standard deviation = 119The raw data value, x = Less than 11Sample size, n = 49

The z-score of the data value is calculated using the following formula

z = (x - mean value)/standard deviation

Substitute the given parameters in the above equation

z = (11 - 1428)/119

Evaluate the quotient

z = -11.91

The required probability of population mean is represented as

P(x < 11) = P(z <  -11.91)

From the z table of probabilities, we have;

P(x < 11) = 0

Hence, the probability value is 0
