Which number is not written in scientific notation
Answers
Answer:
D. 15x10^20
Step-by-step explanation:
The rule for scientific notation is that the coefficient has to be between 1 and less than 10. This means there is only one digit in front of the decimal. 15x10^20 should be written as 1.5x10^21 to follow the rule.
Answer:
Hey there!
e15 times 10^20 isn't written in scientific notation. For a number to be in scientific notation, the leading number must be between 1 and 10.
Let me know if this helps :)

The student use convenience sampling.
This is convenience sampling because in this type of sampling we use closer part of the population. Here the person is surveying his classmates, the closest samples available. In this type of sampling, it is easy to gather samples because every members are of their class easily available to give the survey.
Hence this type of sampling called convenience sampling.

Step-by-step explanation:
To find the number of terms common to the two arithmetic progressions (APs), we can first determine the general terms of both sequences and then find their common terms.
The first AP has a common difference of 5, and the second AP also has a common difference of 5. We can write the general terms as:
First AP: a₁ = 2, a₂ = 2 + 5, a₃ = 2 + 2 * 5, ..., aₖ = 2 + (k - 1) * 5
Second AP: b₁ = 3, b₂ = 3 + 5, b₃ = 3 + 2 * 5, ..., bₖ = 3 + (k - 1) * 5
Now, we need to find when these two sequences are equal, i.e., aₖ = bₖ:
2 + (k - 1) * 5 = 3 + (k - 1) * 5
Simplifying this equation:
2 + 5k - 5 = 3 + 5k - 5
2 - 5 = 3 - 5
-3 = -3
The equation -3 = -3 is always true, which means that these two sequences are always equal for any value of k. Therefore, the number of terms common to the two APs is infinite, and the correct answer is:
d. None of these
Final answer:
The number of terms common to the two arithmetic progressions is 7.
Explanation:
To find the number of terms common to the two arithmetic progressions (A.P.s), we need to compare the terms of each A.P. and count the number of terms that are the same.
The first A.P. is 2, 5, 8, 11, ..., 98. The common difference between the terms is 3.
The second A.P. is 3, 8, 13, 18, ..., 198. The common difference between the terms is also 5.
To find the common terms, we can use the formula:
Term = First Term + (n - 1) * Common Difference
For the first A.P., we have:
First Term = 2
Common Difference = 3
For the second A.P., we have:
First Term = 3
Common Difference = 5
We need to find the values of 'n' that make the terms of both A.P.s the same. By substituting the values into the formula, we can solve for 'n' and calculate the number of common terms.
The number of terms common to the two A.P.s is 7. Therefore, the answer is option c.
