Answer:
lines t and w must be parallel
Step-by-step explanation:
Angles 8 and 10 are alternate interior angles with respect to transversal r across lines t and w. If those angles are congruent, then lines t and w must be parallel.
Answer:
Step-by-step explanation:
The question required a tree diagram (see attachment)
Required
Determine P(Red)
To do this, we simply each path that leads to red on the attached tree.
So, we have:
P(Red) is then calculated as:
Hence, the probability of selecting Red is 0.44
Answer:
40 ft
Step-by-step explanation:
Answer:
a) 1.24 g/ml
b) 2.4%
Step-by-step explanation:
density = mass/volume
volume of sample = 28.4 - 15 = 13.4mL
density = 13.4/10.8
=1.24 g/ml
percent error
1.27 - 1.24 = 0.03
0.03/1.24 *100% = 2.4% error
