Match the vocabulary word to its correct definition.

1 -> f

2 -> e

3 -> d

4 ->  a

5 ->  c

6 ->  g

7 ->  b

Step-by-step explanation:

Let consider the options as a,b,c,d,e,f,g

1. Bell curve  ->     f

2. Data set   ->      e

3. Histogram   ->   d

4. Mean       ->      a

5. Normal distribution   ->   c

6. Standard deviation   ->    g

7. Variance      ->     b

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.
