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.

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

Simply add 3 and 2. You dont need to worry about the 50.

Or, complete 2x50 and 3x50

Now you would have 100 and 150.

Then add them to get 250.

Finally, divide 250 by 50.

Your answer should be 5

T: x^2 & 3 LT: -x & -3x

Step-by-step explanation:

x^2 has no other like term like: -x^2, 8x^2 or basically no longer "x^2"

3 is the same ^ there is no other single integer

(We cannot use -3x because it has an x attached to it)

-x & -3x are like terms because they both have an x to it a single x, not a x with an exponent like x^2

so -x + (-3x) would equal -4x if we wanted to solve it

Answer:

Terms: 3, (-x), x², (-3x)

Like terms: (-x) and (-3x)

Step-by-step explanation:

A term is a single number (positive or negative), a single variable (a letter), or several variables multiplied but not added or subtracted.

Like terms are terms that have the same variables and power like -x.

Answer:

True

Step-by-step explanation:

When you distribute the 3, you get x(2x3)-(12x3)

2x3=6

12x3=36

so 6x-36

and that is equivalent to the first expression.

Answer:

Step-by-step explanation:

a)

The mistaken assumption is that Apple spends "far less" on Research and Development than any of its rivals.

b)

The assumption is incorrect because it took cognizance of the percentage used, and not the actual money spent. In truth, Apple generates far more income than the other two rivals. With Apple generating over $100bn in the said time span, and Google generating $37bn. At the end of the day, Apple spends $2.1bn on Research and Development, while Google spends $5.3bn on the same. This is quite close than the quoted distance of 14% - 2%

c)

Yes, I think so. But only when the 3 companies generate almost the same revenue.

Based on the description of the headline given in the scenario, the solution to the problems posed are :

A.)

The mistake in the assumption is that, the headline focused just on the percentage of the revenue made by each company that is spent on R&D.

B.)

The assumption is incorrect because, the revenue generated by the companies aren't the same. Hence, making comparison based on the percentage alone is incorrect.

C.)

The headline may be correct only when the revenue generated by each company is the same.

40 baskets

Step-by-step explanation:

Find out how many baskets she can make in an hour. Since she makes 4 in 1/2 an hour, multiply 4 by 2 to find out how much she makes in an hour. She makes 8 baskets an hour, so multiply 8 by 5. 8 x 5 = 40.

Answer:

40 Baskets

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
