Answer:
Step-by-step explanation:
Since the sequence is geometric (it multiplies the previous number each time). The nth term sequence would be
Because the sequence multiplies by 3 each time, The base number in that equation would be .
So of the equation would be:
.
Compare the 2 equations:
4, 12, 36
3, 9 ,27
The difference between the 2 equations is: 1, 3, 9 which itself is a geometric sequence so the nth term of this new equation is: .
Combine these 2 equations together and you get:
.
Answer: mean=87, median=87.5 and range=18
Step-by-step explanation:
Mean:
First add all the numbers
78+95+77+92+87+79+94+86+88+94 = 870
Then you divide the answer by counting the numbers
870÷10
=87
Median:
First arrange the numbers in ascending order (from smallest to largest)
77, 78, 79, 86, 87, 88, 92, 94, 94, 95
pick the two middle numbers which is 87 and 88
then you do
= 175÷2
= 87.5
range = Largest number - smallest number
= 95-77
= 18
Answer:
The minimum total distance the employee may have driven before getting stuck in traffic is 8.3 miles
Step-by-step explanation:
* Lets explain how to solve the problem
- The rule of the distance between to points
and i s
- So at first we will find the distance between the three points
∵ A = (-3 , 1) , B = (3 , 3) , C = (3 , -1)
- By using the rule of distance
∴
∴
∴
∵ Each unit coordinate plane represents 1 mile
∵ AB = 6.3 units
∴ The distance between branches A and B = 6.325 miles
∵ BC = 4 units
∴ The distance between branches B and C = 4 miles
∵ AC = 6.3 units
∴ The distance between branches A and C = 6.325 miles
- A bank employee drives from Branch A to Branch B and then
drives halfway to Branch C before getting stuck in traffic
∵ The distance from branch A to branch B is 6.325 miles
∵ The distance from branch B to branch C is 4 miles
∵ The half way from branch B to branch C = 1/2 × 4 = 2 miles
∴ The distance the employee may have driven before getting
stuck in traffic = 6.325 + 2 = 8.325 miles
∴ The minimum total distance the employee may have driven
before getting stuck in traffic is 8.3 miles
