Answer:
The conjecture is that the unit digit of 4^n = 4 when n = odd also 4^n = 6 when n = even
Step-by-step explanation:
The conjecture is that the unit digit of 4^n = 4 when n = odd also 4^n = 6 when n = even
To prove this conjecture
unit digit = 6
hence the property is true for ; n = 1 and n = 2 and also for every odd and even number ( i.e. from 1 to 8 )
Answer:
The number of games for Xbox is about 155
The number of games for PS4 is about 175
Step-by-step explanation:
Let us find the numbers of games for Xbox and for PS4 game
∵ There are 330 video games in the store
∵ 47% of them were for Xbox
- Multiply 47% by 330
∴ The number of games for Xbox = 47% × 330
∵ 47% =
∴ The number of games for Xbox = × 330
∴ The number of games for Xbox = 155. 1
∴ The number of games for Xbox ≅ 155
∵ 53% of them were for PS4
- Multiply 53% by 330
∴ The number of games for PS4 = 53% × 330
∵ 53% =
∴ The number of games for PS4 = × 330
∴ The number of games for PS4 = 174.9
∴ The number of games for PS4 ≅ 175
