What does the left y-axis show?
a-sea surface temperature anomaly, in degrees celsius
b-sea surface temperature anomaly, in degrees fahrenheit
c-time, in four-year intervals
d-incidence of cholera, as a percentage of the normal rate
e-sea surface temperature, in degrees celsius

Explain the difference between each pair of concepts. a. frequency and relative frequency b. percentage and relative frequency a. select the correct choice below. a. frequency is the total number of observations in a data set. relative frequency is the number of times a particular distinct value occurs. b. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of a value to the total number of observations. c. frequency is the total number of observations in a data set. relative frequency is the ratio of the number of times a particular distinct value occurs to the frequency. d. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of two different values.

Suppose a comet has an orbital period of 309.1 years around the sun. what is it’s average distance from the sun?

Three resistors are connected in series across a 15-v power supply. if the potential drops across resistors 1 and 2 are 4.1 volts and 3.1 volts, what is the exact potential drop (in volts) across resistor 3?
