Answer:
The system of equations =
25 + 0.05x = 12 + 0.09x
The number of stickers where the cost of both printers to be equal is 325 stickers
Step-by-step explanation:
Let the number of stickers = x
Printer 1
Pop Art Printing would charge a $25 setup fee and $0.05 per sticker.
$25 + $0.05× x
25 + 0.05x
Printer 2
Sticky Slogans would charge a $12 setup fee and $0.09 per sticker.
$12 + $0.09 × x
12 + 0.09x
We equate both equations together
The system of equations =
25 + 0.05x = 12 + 0.09x
Collect like terms
25 - 12 = 0.09x - 0.05x
13 = 0.04x
x = 13/0.04
x = 325 stickers
Therefore, the number of stickers where the cost of both printers to be equal is 325 stickers
Answer:
182
Step-by-step explanation:
Add 178 + 209 + 159 = 546
Then divide 546 by 3 = 182
Answer: -1
Explanation: The subscript (3) under 6 has no value so 6 subscript 3 is just 6. Use BEDMAS to solve for the equation (Brackets, Exponents, Division, Multiplication, Addition, Subtraction)
1. 6 x 2 - 24 / square root 16 + (8)
2. 6 x 2 - 24 / 4 + 8
3. 6 x 2 - 24 / 12
4. 12 - 24 / 12
5. -12 / 12
6. -1
Therefore the answer is -1.
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.
