Answer:

9 cents per day

Step-by-step explanation:

1 week = 7 days

Each razor lasts 1 week = 7 days

10 razors last 10 weeks = 10 * 7 days = 70 days

cost per day = (total cost)/(number of days)

cost per day = $6.30/(70 days) = $0.09/day

State whether the following variables have a positive correlation, negative correlation, or no correlation.
muminat

The types of correlation seen between positive correlation, negative correlation, or no correlation, in the variables is:

  • a. Height of a person and how often he or she attends religious services. - No correlation
  • (b.)Average property tax in a school district and salary of teachers - Positive correlation
  • (c.)Weight of a person and shoe size. - Positive correlation

<h3>What is the correlation between property taxes and teacher salaries?</h3>

One of the main sources of funding for school districts is the property tax charged. This means that increased property taxes will lead to more money being available for teacher salaries which might then increase. There is therefore a positive correlation between the two.

The same is true for the weight of a person and shoe size. This is because the heavier a person is, the larger their shoe size according to research.

There is however no correlation between the height of a person and their attendance of religious services.

B) If the line is parallel, that means the slope is the same.
    The slope for the original line is \frac{-1-0}{6-2} = \frac{-1}{4}.
    The second form of coral line would be y = -1/4x + (any number). You could          use y = -1/4x + 3.

c) Solve 12x = 24 + 3y for y.
    3y = 12x - 24
    y = 4x - 8
    Perpendicular lines have negative reciprocal slopes... the negative reciprocal      for -1/4 is 4. So yes, the third coral structure is perpendicular to the first coral.
