Answer:

4th term = 29

to generate the terms, substitute n = 2, 3, 4 into the rule

noting that b(1) = - 7

b(2) = b(2 - 1) + 12 = b(1) + 12 = -7 + 12 = 5

b(3) = b(3 - 1) + 12 = b(2) + 12 = 5 + 12 = 17

b(4) = b(4 - 1) + 12 = b(3) + 12 = 17 + 12 = 29

The shape of the distribution that would be expected of income is a <u>Positive Skew. </u>

<h3>What is the shape of a distribution on income?</h3>

Income distribution in the world is such as only 1% earn more than the other 99%. This means that most people will be to the left of such a distribution.

A positively skewed distribution has more variables on the left which makes income a positively skewed distribution.

Three girls collected geodes in the desert. Corinne collected 11 1/8 pounds, Ellen collected 4 5/8 pounds, and Leonda collected

prisoha [69]

Just add:
3 3/4+4 5/8=3 6/8+4 5/8= 8 3/8

then subtract:
11 1/8 - 8 3/8= 2 3/4

so she had 2 3/4 more that the other two
