Answer:

Fraction= 827/100

Desmial= 8.27000

Step-by-step explanation:

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "2.8" was replaced by "(28/10)". 2 more similar replacement(s)

STEP1:

Simplify 14/5

The equation at the end of step1:

547/100-(0-14/5)

STEP2:

Simplify 547/100    

The equation at the end of step2:

547/100-(-14/5

STEP3:

Calculating the Least Common Multiple :

3.1   Find the Least Common Multiple

The left denominator is:      100

The right denominator is :      5

Number of times each prime factor

appears in the factorization of: Prime

Factor  Left

Denominator  Right

Denominator  L.C.M = Max

{Left,Right}

2 2 0 2

5 2 1 2

Product of all

Prime Factors  100 5 100

    Least Common Multiple:

     100

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 Denominator by  L_Deno

  Denote the Right Multiplier by  R_Deno

  Left_M = L.C.M / L_Deno = 1

  Right_M = L.C.M / R_Deno = 20

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 an equivalent fraction, multiply the numerator of each fraction, by its respective Multiplier.

  L. Mult. • L. Num.      547

  ——————————————————  =   ———

        L.C.M             100

  R. Mult. • R. Num.      -14 • 20

  ——————————————————  =   ————————

        L.C.M               100  

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, but the sum or difference over the common denominator then reduces to the lowest terms if possible:

547 - (-14 • 20)     827

————————————————  =  ———

      100            100

Final result :

 827          

 ——— = 8.27000

 100          

Hope this helps!

An education firm measures the high school dropout rate as the percentage of 16 to 24 year olds who are not enrolled in school a
posledela

Answer:

The value of the test statistic z = -0.6606

Step-by-step explanation:

From the question we are told that

      The high dropout rate is \mu  = 6.1%  = 0.061

      The  sample size is  n = 1000

       The  number of dropouts x = 56

       The probability of having a dropout in 1000 people  \= x  = \frac{56}{1000}  =  0.056

Now setting up Test Hypothesis

 Null  H_o :  p = 0.061

 Alternative  H_a : p < 0.061        

The Test statistics is mathematically represented as

                 z = \frac{\= x - p}{\sqrt{\frac{p(1 -p)}{n} } }

substituting values

               z = \frac{0.056 - 0.061}{\sqrt{\frac{0.061(1 -0.061)}{1000} } }

               z = -0.6606
