3 and -3 are said to be the square roots of 9. A square root is written with a radical symbol √ and the number or expression inside the radical symbol, below denoted a, is called the radicand. ... Negative numbers don't have real square roots since a square is either positive or 0.

Sauron [17]

Answer:

-13            

 ——— = -0.20635  

 63            

Step-by-step explanation:

Step  1  :

           7

Simplify   —

           9

Equation at the end of step  1  :

 4    7

 — -  —

 7    9

Step  2  :

           4

Simplify   —

           7

Equation at the end of step  2  :

 4    7

 — -  —

 7    9

Step  3  :

Calculating the Least Common Multiple :

3.1    Find the Least Common Multiple

     The left denominator is :       7  

     The right denominator is :       9  

       Number of times each prime factor

       appears in the factorization of:

Prime  

Factor   Left  

Denominator   Right  

Denominator   L.C.M = Max  

{Left,Right}  

7 1 0 1

3 0 2 2

Product of all  

Prime Factors  7 9 63

     Least Common Multiple:

     63  

Calculating Multipliers :

3.2    Calculate multipliers for the two fractions

   Denote the Least Common Multiple by  L.C.M  

   Denote the Left Multiplier by  Left_M  

   Denote the Right Multiplier by  Right_M  

   Denote the Left Deniminator by  L_Deno  

   Denote the Right Multiplier by  R_Deno  

  Left_M = L.C.M / L_Deno = 9

  Right_M = L.C.M / R_Deno = 7

Making Equivalent Fractions :

3.3      Rewrite the two fractions into equivalent fractions

Two fractions are called equivalent if they have the same numeric value.

For example :  1/2   and  2/4  are equivalent,  y/(y+1)2   and  (y2+y)/(y+1)3  are equivalent as well.

To calculate equivalent fraction , multiply the Numerator of each fraction, by its respective Multiplier.

  L. Mult. • L. Num.      4 • 9

  ——————————————————  =   —————

        L.C.M              63  

  R. Mult. • R. Num.      7 • 7

  ——————————————————  =   —————

        L.C.M              63  

Adding fractions that have a common denominator :

3.4       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

4 • 9 - (7 • 7)     -13

———————————————  =  ———

      63            63  

Final result :

 -13            

 ——— = -0.20635  

 63

What is -7/2y = 21/2 what is the solution_______? Brainliest is on the mark if 10 point will be added as well!
miss Akunina [59]

Answer:

y= -3

Step-by-step explanation:

(-7/2)y  =21/2

Divide both sides by (-7/2) = Multiply by (-2/7)

On the left side ,after cancellation you have only  y

On the right side you multiply 21/2 by (-2/7)

y= (21*-2) / 2*7

y=(-42)/14

y=(-21)/7

y=- 3    

check:

-(7/2) of- 3 is  10.5         21/2=10.5

Answer:

d) $128.65

Step-by-step explanation:

The table format from the question can be properly expressed as :

                       Coefficients       Standard Error     t Statistic    p  value

Intercept           39.14942          22.30182             1.755436     0.109712

x                         1.792312          0.407507             4.398234    0.001339

Source            df            SS                MS             F             S_e = 29.51443

Regression      1       16850.99      16850.99   19.34446    r^2 = 0.682478

Residual          9       7839.915       871.1017

Total               10       24690.91

For a rural household with $90,000 annual income, Abby's model predicts weekly grocery expenditure of:_________.

The estimated regression equation is as follows:

Expenditure (y) = 39.15 + 1.79 x

For a rural household with $90,000 annual income; the independent variables will assume the following values

x = 50

Thus; the estimated groceries expenditure is computed from the above regression equation by replacing the values of the independent variables;

This can be expressed as:

y = 39.15 + 1.79 (50)

y = 39.15 + 89.5

y = $128.65
