Answer:
he did half the diameter
Step-by-step explanation:
visa cards begin with 4 and then have 13 or 16 digits but here we have a number beginning with 4 and then it has the 15 digits.
<u>Step-by-step explanation:</u>
- Each card has a different first digit number. The maximum length of this type of credit card number can be up to 19 digits.
- In the visa card starting 6 digits are always said to be the issuer identifier.
- The visa cards will have the starting digits as 4 whereas in Mastercard the starting digit is 5 but it has 16 digits numbers.
The question is incomplete: the table and the answer choices are missing.
This is the table:
House 1 2 3 4 5 6 7 8
<span>
Size 1025 1288 2344 988 12,985 1500 1077 2455
</span>
These are the answer choices:
<span>
A) maximum
B) mean
C) median
D) range
</span>
Answer: option C) median.
Explanation:
You have to calculate or analyze every statistics before and after.
A) Máximun.
Before correcting the error, the maximum was 12,985 (the measure of the house 5).
After correcting the error, the new maximum is 17,985 (the corrected measure of house 5). So, this changed 17,985 - 12,985 = 5,000 (square feet).
B) Mean
<span>Increase in the mean = change in the measure / number of houses = 5,000 / 8 = 625 square feet

</span><span>
</span><span>
</span>Since, the error only modified the maximum value, the median did not change.
With the error and without the error it is the average of the two central measures: [1288 + 1500] / 2 = 1,394 square feet.
Then, this measure did not change, and this is the right answer.
D) Range:
The range is the difference between the maximum and the minimum data.
Since, the maximum data changed, the range changed.
Divide 2 3/4% by 100% to obtain the fraction 0.0275. This decimal fraction can be reduced to 11/400.
