Answer: The answer is 12 ways.
Step-by-step explanation: Given that For members of Abe's family are travelling to Canada for vacations. They have four seats in the centre section of the plane. Also, Abe wants to sit next to his brother Ben. We need to find the number of ways in which they can sit.
Since Abe will sit next to his brother Ben, so we can count both of them as one. Hence, taking them as one member, three members can sit in 3! ways.
Also, Abe and Ben among themselves can sit in 2! ways.
Therefore, the total number of ways in which they can sit
= 3! × 2!
=3 × 2 × 1 × 2 × 1
=12.
Thus, the number of ways is 12.
The mean distance for an ungrouped data can be calculated by adding the given data and dividing it to the number of data. In this given problem, the mean distance is equal to the summation of distances/number of students.
In other words, 83 miles/20 = 4.15 miles or 4.2 miles
We start with the sale at $5,000. The growth is: p = 10% = 0.1; r = 1 + 0.1 = 1.1
The equation is:
f ( t ) = 5,000 * ( 1.1 )^t
where t it the time in months.
f ( 6 ) = 5,000 * ( 1.1 )^6 =
= 5,000 * 1.77156 = $8,857.80
Answer: The sale 6 months from now will be $8,857.80.
Answer:
-9
Step-by-step explanation:
9=b-2b
9=-b
divide both sides by -
b=-9
Answer:
-1, 3, 7
Step-by-step explanation:
y = 4(-1) + 3
y = -4 + 3
y = -1
y = 4(0) + 3
y = 0 + 3
y = 3
y = 4(1) + 3
y = 4 + 3
y = 7
