Vesnalui [34]

Answer:

Kindly check explanation

Step-by-step explanation:

Given the data on the result of math exam in Ben's class

{35,42,56,68,69,72,72,77,78,78,82,85,87,88,90,93,94,96,96,99}

The 85th percentile score represents the score in which 85 percent of the students in Ben's class or below obtained in the test.

The 85th percentile score :

85%(n+ 1) term

n = number of observations = 20

0.85(20 + 1)th term

0.85(21) = 17.85 term

Take the average of the 17th and 18th terms

(94 + 96) / 2

= 190 / 2

= 95

Evaluate log 2 base 8​
iren2701 [21]

Answer:  The correct answer is:  " 3 " .

_______________________________

Step-by-step explanation:

_______________________________

The problem given is:

_______________________________

Evaluate:  log 2 base 8 .

_______________________________

Rewrite as:  " log_2}8 = ? _______________  " ;  log_2}8 = ? _______________

_______________________

Take note of the following definition of a logarithm:

_______________________

"   log_{m}n = a " ;  ↔  " m^{a} =n  "  ;

_______________________

in which:  m  refers to the "base" ;

               n  refers to the "argument" ;

               a  refers to the "exponent" ;

______________________________

As such:

       " log_2}8 = ? _______________ "

      ⇔ " 2^{x} = 8 " ; Solve for "x" ;  

 _______________

 Note:  

  2⁰ = 1 ;

  2¹ = 2 ;

  2² = 2 * 2 = 4 ;

  2³ = 2 * 2 * 2 = 8 .

___________________

 → " 2^{x} = 8 " ;

 → " 2^{3} = 8 " ;  since: " 2^{3} = 2  *2 *2 = 8 " ;

 → as such:   " x = 3  " ;

______________________

Thus:

"log 2 base 8 " ;

          = log{_{2}}8 = 3  .

_______________________

Hope this helps!

Best wishes to you!
