Answer:
38 degrees.
Step-by-step explanation:
There are 180 degrees in a triangle, so
m<1 = 180 - (43 + 74)
= 180 - 117
= 63 degrees.
m < 2 = m < 1 ( opposite angles) so
m < 2 = 63 degrees.
Finally, m < 3 = 180 - (63 + 79)
== 180 - 142
= 38 degrees.
Answer:
9. B, C, D
10. A, D, E
Step-by-step explanation:
9. A. Students who bring lunch do not represent cafeteria purchases.
B. - D. Are randomized.
10. A. 1/4 of 50 is 12.5. about equal to 12
B. 12% of 50 is 6. not equal to 12
C. 12 ÷ 50 = 24. 3,000 × 0.24 = 720. not less than 500
D. (see above work) 720 = 720
E. 3,000 - 720 = 2,280. more than 2,000
Answer:
3 2/6
Step-by-step explanation:
<u>total pages to be written</u>
add 4 to 1/2 using common denominators
4 1/2 = 8/2 + 1/2
= 9/2 or 27/6
<u>pages Marcus wrote</u>
add 1 to 1/6 using common denominators
1 1/6 = 6/6 + 1/6
= 7/6
<u>pages left</u>
27/6 - 7/6 = 20/6 or 3 2/6
Based on the information given...
Experimental - how many times something occurs over how many times experiment is done
Odd number rolled - 8 times
Total times done - 20
This would mean the experimental probability is 8/20
Theoretical - favorable outcomes over possible outcomes
On a 6 sided number cube, you have 3 chances of rolling an odd, over 6 possible roll outcomes
This would mean the theoretical probability is 3/6 or 1/2
