It takes my’khiyah 40 seconds to run 1/3 of a lap. How many laps can she run in 5 minutes
kakasveta [241]
Answer:
number of laps = 5/2 = 2.5 laps 

Explanation:
First, we will need to convert the minutes to seconds.
5 minutes = 5 * 60 = 300 seconds

Now, we know that she can run 1/3 of a lap in 40 seconds. To know the number of laps that she can run in 300 seconds, all we have to do is cross multiplication as follows:
40 seconds .................> 1/3 laps
300 seconds ................> ?? laps
number of laps = (300 * 1/3) / 40
number of laps = (100) / 40
number of laps = 5/2 = 2.5 laps

Hope this helps :)

Whats is 0.000001 written as a power of ten
siniylev [52]
You need to move the decimal point to be at 1.

Since this is a decimal, the power will be negative.

I had to move the decimal 6 places.

So,

1^-6

Which correlation coefficient could represent the relationship in the scatterpot. Beach visitors
adoni [48]

Answer:

A. 0.89.

Step-by-step explanation:

The value of correlation coefficient ranges from -1 to 1. Any value outside this range cannot possibly be correlation coefficient of a scatter plot representing relationship between two variables.

The scatter plot given shows a positive correlation between average daily temperatures and number of visitors, as the trend shows the two variables are moving in the same direction. As daily temperature increases, visitors also increases.

From the options given, the only plausible correlation that can represent this positive relationship is A. 0.89.
