They are pairs on the corridinant
The answer is b! Hope this helped
I will show you how to do #5:
a). -20 + 2(n-1) Original Expression
-20 +2n - 2 Distributive Property
-22 + n Combine Like Terms
Final Expression: -22 + n
b). 1.5 + (-2.5)(n -1) Original Expression
1.5 + -2.5n + 2.5 Distributive Property
4 - 2.5n Combine Like Terms
Final Expression: 4 - 2.5n
Given data:
The given distance Jadwiga runs in a day is 875 m.
The expression for the given statement is,
1d=875 m
Multiply the above expression by 7 on both sides.
7(1 day)=7(875 m)
=6,125 m
=6.125 km
Thus, Jadwiga covered 6.125 km in 7 days.
The theoretical probability is what is expected based on using math. Since there is only one card that is number 1, and there are 400 possible outcomes, then the theoretical probability is 1/400 which is 0.25%.
Now find the experimental probability by find the number of times card 1 is picked, and the number of cards in total. 128/400 = 0.32 which is 32 percent.
The experimental probability is higher than the theoretical probability.
