Answer:
<h2> Assuming your friend said the temperature over there was 68 degrees Fahrenheit in degrees C it would be 20 °C</h2>
Step-by-step explanation:
The question is not complete, as the information, your best friend in Europe about the temperature over there is missing, nevertheless, we can proceed with this problem by plugging in an assumed temperature.
The expression for conversion from degrees F to degrees C is given as
T(°C) = (T(°F) - 32) × 5/9
Now say temperature your friend e-mailed you is 68 degrees Fahrenheit (you can as well plug in your own value)
T(°C) = (68°F - 32) × 5/9
T(°C) = (36) × 5/9
T(°C) = 180/9 = 20 °C
T(°C) = 20 °C
The value of r indicates the negative correlation.
<h2>Given </h2>
Rikki decided to collect data to determine if a runner's time and speed are correlated.
She determined the data to have a correlation coefficient of -0. 5.
<h3>What is the correlation coefficient?</h3>
The correlation coefficient is a statistical measure that calculates the strength of the relationship between the relative movements of the two variables.
She determined the data to have a correlation coefficient of -0. 5.
Here, the coefficient is negative which is -0.5.
This correlation coefficient indicates that there exists a weak negative correlation between the runner’s time and the speed.
This relation is negative because the correlation coefficient is negative.
Hence, The value of r indicates the negative correlation.

Farmer Gray planted 300 seeds.
To find this, you simply multiply the number of flower pots (30) by the number of seeds in each pot (10). Thus making the answer 300.
I hope this helps!
