In order to figure out how many cars she must wash, first you should figure out how much money total you need.  This week, she needs $25 for her weekly earnings + $65 for spending money = $90.  Then you divide the total amount of money, $90, by 7.  The answer is 12.8, but because you can't wash 12.8 cars, the answer is 13.

Tukey HSD Interpretation
Mariulka [41]

Answer:

The solution can be defined as follows:

Step-by-step explanation:

They also have a significant outcome in our instance. Its value of F is 1.773, with such a p-value of 0.212 achieved meaning (which is greater than the .05 alpha level). It means that the press with different levels of stress of the stress variable may not differentiate objectively.

Even so, we still do not know which one of the multiple mechanisms is significant. They realize the diff. To do just that, the results of the Tukey HSD test should be regarded.

HSD Tukey

Looking at the Multiple Correlations table below, you will see that mean values were created for the standard deviation among pairs of various stress varying concentrations (High - Low; High - Medium )

This can be seen on one-way ANOVA(1.773, p=.212), there's no statistically significant difference between the groups. A Tukey post hoc study has observed that the increase among medium and high stress is statistically significant, as well as the difference among low, medium, and high stress is important.

3. if you want to represent geologic time with a 24-hour clock, how many years would be represented by a single second, minute a
Amanda [17]

In geologic time scale a single second = 52,083.3 years, a minute = 3,125,000 years, an hour = 187.5 million years

Geologic time, the extensive interval of time occupied by the geologic history of Earth. Formal geologic time begins at the start of the Archean Eon (4.0 billion to 2.5 billion years ago) and continues to the present day.

So the geologic time scale (GTS) contains different ranks of times about Earth, obviously you know this already. However, the GTS has these different ranks in order from shortest length of time to longest length of time.

The Earth is about 4.5 billion years old. We want to convert this geological time in a period of 24 hours. So, if 24 hours correspond to 4.5 billion years, then, 1 Hour= 4.5 billion / 24=187.5 million years. There are 60 minutes in an hour ∴ 1 minute =187.5 million /60=3,125,000 years finally, one second has 60 seconds ∴ 1 second=3,125,000 / 60 = 52,083.3 year.
