Answer:

The required inequality is: 12 ≤ 3x < 21

Step-by-step explanation:

We are given: three times a number is greater than or equal to 12 and less than 21

We need to answer following questions:

1) The inequality translated in numerical form

Let number = x

12 ≤ 3x < 21

2) Your work solving the inequality

We need to find value of x. Divide the inequality by x

4 ≤ x < 7

3) The solution graphed on a number line

It is shown in figure attached.

4) The solution in set notation

The set notation is: Considering x belongs to natural numbers N

{∀ x|x∈N, 4 ≤ x < 7}

5) The solution in interval notation

The interval notation is: [4,7)

because we have 4 less than equal to x and x is less than 7

Answer:

The complex solution would be: X = 5,1

Step-by-step explanation:

Answer:

x=1

TRUE because Factoring  x2-6x+5

The first term is,  x2  its coefficient is  1 .

The middle term is,  -6x  its coefficient is  -6 .

The last term, "the constant", is  +5

Step-1 : Multiply the coefficient of the first term by the constant   1 • 5 = 5

Step-2 : Find two factors of  5  whose sum equals the coefficient of the middle term, which is   -6 .

     -5    +    -1    =    -6    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -5  and  -1

                    x2 - 5x - 1x - 5

Step-4 : Add up the first 2 terms, pulling out like factors :

                   x • (x-5)

             Add up the last 2 terms, pulling out common factors :

                    1 • (x-5)

Step-5 : Add up the four terms of step 4 :

                   (x-1)  •  (x-5)

            Which is the desired factorization

Step-by-step explanation:

The answer for x in the solution is -5

Answer:

3/4

Step-by-step explanation:

The value of cos C x sin A is 3/2.

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

AB = 1

AC = 2

BC = √3

Now,

∠B = 90°

∠A = 60°

∠C = 180 - (90 + 60) = 180 - 150 = 30°

cos C = cos 30° = √3 / 2

sin A = sin 60° = √3/2

Now,

Cos C x Sin A

= √3/2 x √3 / 2

= 3/2

Thus,

The value is 3/2.

Answer:

[tex]0 \leq p < 6[/tex]

Step-by-step explanation:

Given

[tex]t = 6.95p + 29.95[/tex]

[tex]Amount = 70[/tex]

Required

Determine the domain

First, we need to solve for p

Substitute 70 for t in [tex]t = 6.95p + 29.95[/tex]

[tex]70 = 6.95p + 29.95[/tex]

Collect Like Terms

[tex]6.95p = 70 - 29.95[/tex]

[tex]6.95p = 40.05[/tex]

Solve for p

[tex]p = 40.05/6.95[/tex]

[tex]p = 5.76[/tex]

This implies that Larry can not invite up to 6 people.

Hence, the domain can be represented as: [tex]0 \leq p < 6[/tex]

Answer: what you need to do is multiply 3 times 1 and add 2 to the sum that you get which would be 5/3 for the first one because you keep the same denominator! Just multiply the denominator the bottom number and add the numerator the top number to your sum that you got from multiplication! Do that for all of them and you should get an improver fraction!

:)

Finding the reciprocal is easy just flip the numbers I’m in 6th grade I learn this already!

For example just flip 3/7 to 7/3

Answer:

1. 5/2 2. 18/5 3. 35/5 4. 38/3 5. 72/7 1. 7/3 2. 3/8 3. 1/9 4. 8/33 5. 3/44

Step-by-step explanation:

to make mixed numbers into improper fractions, you multiply the whole number by the denominator, and add the numerator. you take that answer and make it the numerator in the new improper fraction, and keep the same denominator.

to take the reciprocal switch the numerator and the denominator.

Step-by-step explanation:

[tex]4.302(20) - 3.293 = 82.747[/tex]

The mean value of the response variable is 82.747.

Linear Regression calculates the equation of the line that is the best fit for the given data points. Linear regression models a linear relationship between the input variable x and the output variable y.

Here, given regression line;

        y= 4.302x - 3.293    ...............(i)

Now, value of x is given; x = 20

Put the value of x in equation (i), we get

     y = 4.302 X 20 - 3.293

     y = 86.04 - 3.293

     y = 82.747

Thus, the mean value of the response variable is 82.747.

For every 3 you get a 4

So 5*3= 15 and 5*4=20

25/10 = 5//2 is another one.

Answer:

25/10 = 5/2

3/4 =15/20

Step-by-step explanation:

The description of the relationship between the real zero(s) and x-intercept(s) of the function should be option A.

Since it is given that

f(x) = 3x(x - 1)

x2(x+3)(x + 1)

Also, the function should be set out and equivalent to zero when x = 1

and, the graph should have an x-intercept of (1,0).

Therefore, the option A is correct.

Step-by-step explanation:

Answer:

E[X] = 1

Var[X] = 1

Step-by-step explanation:

We are told that n people enter the restaurant and put their hats at the reception.

This means that there are n hats.

Also, we are told that eeach person gets a random hat back when going back after having dinner.

Thus, each person will pick a hat uniformly at random and will get a right hat back with the probability: 1/n.

The expectation is linear even though the random variables are dependent. Thus, the expected mean of the total number of persons who get their right hat back is: E[X] = n × 1/n = 1

Now, the variance in hat problem is given by;

Var[X] = E[X²] - E[X]²

This gives;

Var[X] = E[X²] - 1

Now, E[X²] is expressed as;

E[X²] = n(1/n) + n(n - 1)•(1/n)•(1/(n - 1))

E[X²] = 1 + 1

E[X²] = 2

Thus;

Var[X] = 2 - 1

Var[X] = 1
