How I can answer this two question please 1. What does the sign of the correlation coefficient (`r=-0.83`) tell you about the relationship between the number of bacteria colonies and the concentration of antibiotic in the dish?

2. What does the numerical value of the correlation coefficient (`r=-0.83`) tell you about the relationship between the number of bacteria colonies and the concentration of antibiotic in the dish?

look up a corrdinate plane and do what the thingy says and boom

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
