Answer:

Step-by-step explanation:

The proportion of students in a psychology experiment who could remember an eight-digit number correctly for t minutes was :

0.9 − 0.3 ln(t)

the proportion that remembered the number for 5 minutes, we would substitute t = 5 into expression, 0.9 − 0.3 ln(t). It becomes

0.9 − 0.3 ln5

= 0.9 - 0.3 × 1.60943791243

= 0.9 - 0.4828

= 0.4172

Approximately 0.4 to 1 decimal place

Find a formula for the nth term in this arithmetic sequence:
Sati [7]

The nth term of the arithmetic sequence is Tn = -7 + ( n - 1) 6

<h3>What is an arithmetic sequence?</h3>

An arithmetic sequence is defined as a sequence of numbers where the differences between every two consecutive terms is the same  through out the sequence.

The nth term of an arithmetic sequence is expressed as;

an = a + ( n - 1) d

Where;

  • a is the first term
  • n is the number of terms
  • d is the common difference

Substitute the values

an = -7 + ( n - 1) 6

Thus, the nth term of the arithmetic sequence is Tn = -7 + ( n - 1) 6
