<span>For problem 8:
sin A/a sinB/b = sinC/c
so sin50/15 = sinB/12
0.766/15 =sinB/12
0.051066 = sin B/12
sin B = 0.6128
B = 37.79 degrees
sum of angles must equal 180 deg therefore C = 180-50-37.79 = 92.21 degrees and .766/15 = sin92.21/c
.051066= 0.99925/c
c = .99925/0.051066 = 19.567
Problems 9 and 10 can also be done with the same method as problem 8.

We can factor
And now we know all the terms involved: substitute every occurrence of xy with 7 and every occurrence of x-y with 5 to have
Answer:
its 42
Step-by-step explanation:
i took it edg
{-15(1.5) + {(-2.5)(1.25)}}
{-22.5 + (-3.125)}
{-22.5 - 3.125}
-25.625
The statement that is true about the dot plots is: Range for Week 1 equals range for Week 2.
<h3>What is the Range of a Data Set?</h3>
Range is simply the difference between the highest data point and the lowest data point in a data set.
Range for Week 1:
Range = 89 - 62
= 27
Range for Week 2:
Range = 89 - 62
= 27
The sentence of median and mean doesn't satisfy the situation.
Hence, Range for Week 1 equals range for Week 2.
