Remember, "mean" means the average of the numbers.
In order to find an average, add all the numbers together, then divide by the amount of numbers.
So:
1+5+7+9+11+16+18+20+30+35=153
Since there are 10 numbers in the sequence, divide by 10.
153/10=15.3
Answer:
Step-by-step explanation: 3004 x 10⁻⁶
These numbers were written in standard forms or in scientific notation or in compressed manner
4 x 10⁻⁶ = 0.000004
3 x 10⁻₃ = 0.003
Adding the two together gives
0.000004 + 0.003 = 0.003004
= 3004 x 10⁻⁶

Answer:
Caleb arrived first 2 hours before Alyssa
Step-by-step explanation:
To solve the situation, find the speed per hour they were driving by dividing the distance they drove by the time it took.
Alyssa drove 105 miles in 3.5 hours or 105/3.5 = 30 miles per hour.
Caleb drove 168 miles in 4 hours or 168/4 = 42 miles per hour.
Since they both left at the same time and drove the same 210 miles to the beach, Caleb arrived first since he was driving faster.
He arrived in 210/42 = 5 hours.
Alyssa arrived in 210/30 = 7 hours.
He arrived 2 hours before her.
In an Arithmetic sequence, the difference between two consecutive terms of the sequence remains the same. This difference is known as common difference.
If we observe the given options, we can note:
In option A, the difference between two consecutive terms is the same and is equal to 1.
In option B, the difference between two consecutive terms is the same and is equal to -2.
In option C, the difference is not the same.
In option D, the difference between two consecutive terms is the same and is equal to 5.
In option E, the difference is not the same.
So, the correct options are A,B and D
