The figure below shows a line graph and two shaded triangles that are similar: which statement about the slope of the line is true?
the slope from point o to point a is one-fourth times the slope of the line from point a to point b.
the slope from point o to point a is four times the slope of the line from point a to point b.
it is fraction negative 1 over 4 throughout the line.
it is –4 throughout the line.

Add the fractions, and simply the result to lowest terms. 2/3 + 2/7= ?

Christine wong has asked dave and mike to her move into a new apartment on sunday morning. she has asked them both, in case one of them does not show up. from past experience, christine knows that there is a 40% chance that dave will not show up and a 30% chance that mik a. what is the probability that both dave and mike will show up? (round your answer to 2 decimal places.) b. what is the probability that at least one of them will show up? c. what is the probability that neither dave nor mike will show up?
