Answer:
n(B') = 15
Step-by-step explanation:
Assumunin U is the universal set.
B = { 7,11,17,19}
B' = natural numbers different form 7,11,17 and 19 = {1,2,3,4,5,6,8,9,10,12,13,14,15,16,18}
2:25pm
The time given is 5pm to catch the train back to school;
Amount of time for the tour = 1hr 45min
= 105min
Amount of time at gift shop = 30min
Amount of time to save = 20min
Total time = 105min + 30min + 20min = 155min
So;
Total time = 2hr 35min
5pm - 2hr 35min = 2:25pm
She should order 10 orders of the 4-pizza deal from Peat's Pizza
<u>Peat's Pizza deal:</u>
4 x 10 = 40 | 26 x 10 = 260 | so if you choose the Peat's Pizza deal then Tina would have to pay $260.
<u>Pizza Palace deal:</u>
10 x 4 = 40 | 75 x 4 = 300 | so if you choose the Pizza Palace deal then Tina would have to pay $300.
Hope this helps :D
