A- Perpendicular lines have negative reciprocal slopes. Therefore a perpendicular line to 2x-8 will have a slope of -1/2. Once solved in slope intercept form, choice A shows a line of slope -2/4, equivalent to -1/2
congruent angles are of similar measures
congruent angles that are congruent to ∠7:
- ∠6 ( vertically opposite angles )
- ∠3 ( corresponding angles )
- ∠2 ( alternate interior angles )
Answer:
0.1575
Step-by-step explanation:
Probability of picking a girl is 0.45 and probability of a girl scoring A is 0.35.
Therefore probability of a girl scoring A is 0.45*0.35=0.1575
1,113 is the total because all you do is multiply $27 and 33 so you would get 891. Then you multiply 37 and 6 which is 222. After you add 891 + 222. So you get 1,113
