The box plots below show the average daily temperatures in July and August for a U.S. city: two box plots shown. The top one is
sergey [27]

The <em>correct answer</em> is:


The mean for July is smaller than the median; and

the mean for August is larger than the median.


Explanation:


A distribution with a positive skew would have a longer whisker in the positive direction than in the negative direction. A larger mean than median would also indicate a positive skew.


Alternatively, a distribution with a negative skew would have a longer whisker in the negative direction than in the positive direction. A smaller mean than median would also indicate a negative skew.


The whisker in the negative direction for July is longer than the whisker in the positive direction. This indicates a negative skew.


The whisker in the positive direction for August is longer than the whisker in the negative direction. This indicates a positive skew.

Write the equation in standard form.<br> 8−5y=−2x
velikii [3]

Answer:

y = \frac{2}{5}x + 1\frac{3}{5}

Step-by-step explanation:

We have 8 - 5y = -2x

Rearranging gives;

5y = 2x + 8

Dividing through by 5 gives;

y = \frac{2}{5}x + \frac{8}{5}

Simplifying gives;

y = \frac{2}{5}x + 1\frac{3}{5}

This is a standard linear equation form.
