triangle with 2 sides of equal lengths= isoceles
triangle with 3 sides of equal lengths= equilateral
The answer is A:
Because the only difference between the rest of the answer choices are the lower and upper quartiles, that is all you need to find. In order to do so you find the median for the first half (lower quartile) and then find the median for the second half. In this case it is 29 (Q1) and 58 (Q2)
Answer:
a. Ryan 70mph. Janelle 65mph.
b. 4 hours and 48 minutes.
Step-by-step explanation:
a. Ryan 245/3.5=70 mph. Janelle 260/4=65 mph.
b. If Janelle drives 575 miles with the speed of 65 mph, in total it would take her 575/65=8.8 hours, which is 4.8 hours more than 4 hours. (0.8 hours is 48 minutes).
