Answer:
Step-by-step explanation:
The two given numbers both have the denominator 5, Thus the quotient quickly reduces:
11 4/5 becomes 59/5 and 3 1/5 becomes 16/5. Dividing the first expression by the second yields 59/16, which can't be reduced.
However, 59 = 48 + 11, so 59/16 = 48/16 + 11/16, which is approximately 3 1/2 (from either Answer B or Answer C).
The exact answer is 3 11/16; B and C are identical and are closer to 3 11/16 thn 3 or 4.
Answer:
Vincent and Reyna.
Step-by-step explanation:
As z-score indicates that a data point is how many standard deviation above mean, so to find which of three applicant should be offered the job, let us find the z-score for each person using z-score formula.
, where,
= z-score,
= Random sample score,
= Mean,
= Standard deviation.
Therefore, Vincent's score on aptitude test is 1.7 standard deviation above mean.
Therefore, Kaitlyn's score on aptitude test is 0.6 standard deviation above mean.
Therefore, Reyna's score on aptitude test is 1.2 standard deviation above mean.
Since Vincent and Reyna has higher z-scores, therefore, they are further above mean than Kaitlyn. Therefore, Vincent and Reyna should be offered the job.
Answer:
717 * 213 = 152721
Step-by-step explanation:
Given
717 and 213
Required
Multiply
Rewrite in the following form
7 1 7
* 2 1 3
---------------------
Start by multiply 717 by 3
7 1 7
* 2 1 3
---------------------
2 1 5 1
Then multiply 717 by 1
7 1 7
* 2 1 3
---------------------
2 1 5 1
7 1 7
Then multiply 717 by 2
7 1 7
* 2 1 3
---------------------
2 1 5 1
7 1 7
1 4 3 4
Lastly, add the resulting digits
7 1 7
* 2 1 3
---------------------
2 1 5 1
7 1 7
1 4 3 4
--------------------------
1 5 2 7 2 1
<em>Hence; 717 * 213 = 152721</em>
