The radius and circumference of several objects were measured.
Over [174]

A statement which best describes the strength of the correlation, and the causation between the variables is that: D. it is a strong positive correlation, and it is likely causal.

<h3>What is a positive correlation?</h3>

A positive correlation can be defined as a terminology that is used to described a scenario (situation) in which two variables move in the same direction and are in tandem.

This ultimately implies that, a positive correlation exist when two variables have a linear relationship or are in direct proportion. Hence, when one variable increases, the other increases as well, and vice-versa.

By critically observing the scatter plot (see attachment) which models the data in the given table, we can infer and logically deduce that the value on the y-axis (circumference) increases as the value on the x-axis (radius) increases, so this is a strong positive correlation.

Also, we know that there exist a direct relationship between the circumference of a circle and its radius, so this relationship is most likely causal.

In conclusion, a statement which best describes the strength of the correlation, and the causation between the variables is that it's a strong positive correlation, and it is likely causal.

A car bus travels at a speed of 45 km/h. How far will it travel in 36 minutes?​
tensa zangetsu [6.8K]

Correct Question:

A car/bus travels at a speed of 45 km/h. How far will it travel in 36 minutes?

(Note- Corrected part is written in bold.)

Solution:

\sf Speed = 45 \: km/h

\sf Time=36 \: mins

\sf   = \frac{36}{60} \:  hour \: (Since  \: we  \: know,1 \: hour \:  = 30 \: mins

\sf =  \frac{3}{5}  \: hour

\sf \: Distance = Speed \times Time

\sf =  \: 45 \times \frac{3}{5}  \: km

\sf   = \frac{45 \times 3}{5}  \: km

\sf \: Distance=27 \: km

  • Hence, a car/bus travels 27 km in 36 mins.

chubhunter [2.5K]

1 inch equals 250 feet.

Multiply the inches on the map by 250 to get total feet.


30 x 250 = 7,500 feet

24 x 250 = 6,000 feet


The park is 7,500 feet long by 6,000 feet wide
