Please explain how you got your answer!!! The dot plots below show the ages of students belonging to two groups of salsa classes
Rudik [331]

Answer:

Group b most likely has a lower mean age of salsa students

Step-by-step explanation:

Arithmetic Mean of the data is the average of a set of numerical values, calculated by adding them together and dividing by the number of terms in the set.

Here we are given with two groups that are Group A and Group B

both having total number of students = 20

Here the mean age of the data is addition of the all ages of different students divided by total number of students.

For group a

total age of the group = 3 × 5 + 4 × 10 + 6 × 17 + 4 × 24 + 3 × 29

= 15 + 40 + 102 + 96 + 87

=340

The mean age of salsa students= 340 ÷ 20 = 17

For group b

total age of the group = 6 × 7 + 3 × 10 + 4 × 14 + 5 × 16 + 2 × 21

= 42 + 30 + 56 + 80 + 42

=250

The mean age of salsa students= 250 ÷ 20 = 12.5

So the group b most likely has a lower mean age of salsa students

What is the exact distance from (−1, 4) to (6, −2)?
Studentka2010 [4]
Same as last time:

d^2=(x2-x1)^2+(y2-y1)^2

d^2=(6--1)^2+(-2-4)^2

d^2=7^2+(-6)^2

d^2=49+36

d^2=85

d=√85  (85=5*7 and both 5 and 7 are prime so √85 cannot be simplified any further)

The exact distance is √85 units.

Solve for x: 3/4x+5/4=4x?
butalik [34]

Answer:

x = 5/13 = 0.385

Step-by-step explanation:

Step  1  :

           5

Simplify   —

           4

Equation at the end of step  1  :

   3         5    

 ((— • x) +  —) -  4x  = 0

   4         4    

Step  2  :

           3

Simplify   —

           4

Equation at the end of step  2  :

   3         5    

 ((— • x) +  —) -  4x  = 0

   4         4    

Step  3  :

Adding fractions which have a common denominator :

3.1       Adding fractions which have a common denominator

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

3x + 5     3x + 5

——————  =  ——————

  4          4  

Equation at the end of step  3  :

 (3x + 5)    

 ———————— -  4x  = 0

    4        

Step  4  :

Rewriting the whole as an Equivalent Fraction :

4.1   Subtracting a whole from a fraction

Rewrite the whole as a fraction using  4  as the denominator :

         4x     4x • 4

   4x =  ——  =  ——————

         1        4  

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

4.2       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:

(3x+5) - (4x • 4)     5 - 13x

—————————————————  =  ———————

        4                4  

Equation at the end of step  4  :

 5 - 13x

 ———————  = 0

    4  

Step  5  :

When a fraction equals zero :

5.1    When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

 5-13x

 ————— • 4 = 0 • 4

   4  

Now, on the left hand side, the  4  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  5-13x  = 0

Solving a Single Variable Equation :

5.2      Solve  :    -13x+5 = 0

Subtract  5  from both sides of the equation :

                     -13x = -5

Multiply both sides of the equation by (-1) :  13x = 5

Divide both sides of the equation by 13:

                    x = 5/13 = 0.385

One solution was found :

                  x = 5/13 = 0.385
