Answer:
292 CM
Step-by-step explanation:
8x7 = 56 (2 such sides)
6x8 = 48 (2 such sides)
7x6 = 42 (2 such sides)
56(2) + 48(2) + 42(2)=
292
The given in the problem above is an arithmetic sequence with the first term equal to 4 and the common difference is 5. To determine the number of seats on row 23, use the formula,
an = a1 + (n - 1) d
Solving for the 23rd term,
an = 4 + (22) 5 = 114 seats
Therefore, the answer is there are 114 seats on the 23rd row.
Answer: -1320
Step-by-step explanation:
Answer:
1/6
Step-by-step explanation:
Probability = number of ways it could happen / total number of outcomes
Since there are 2 people with brown eyes, so the numerator is 2.
Since there are 12 people in total, the denominator is 12.
Probability = 2/12 = 1/6
