Answer: $1,560
Step-by-step explanation:
Assume the computer's price is x.
This means that expressing the printer in terms of x would be:
= 30% * x
= 0.3x
These two put together represent the cost of $2,028
Expression is:
x + 0.3x = 2,028
1.3x = 2,028
x = 2,028/ 1.3
x = $1,560
Computer was $1,560
Printer was therefore:
= 1,560 * 30%
= $468
Answer:
Explanation:
<em>The line y = -1 </em>is horizontal: parallel to the y-axis.
The point<em> B (2,3)</em> is above <em>the line y = - 1 </em>at a distance equal to the y-coordinate of B (y = 3) less - 1:
When the <em>point B (2,3) </em>is <em>reflected over the line y = -1</em>, the x-coordinate does not change. The image will be 4 units down the line y = -1, thus the y-coordinate will be - 1 - 4 = - 5.
Hence,<em> the coordinates of the vertex B'</em> are x = 2, y = - 5: (2, - 5).
Answer:
Yes
Step-by-step explanation:
85, 85, 90, 90, 95, 95, 100, 100, 150
Median: 95
Q1: (85+90)/2 = 87.5
Q3: 100
IQR: Q3 - Q1 = 100 - 87.5 = 12.5
1.5 × IQR = 18.75
Outliers are outside the interval:
[Q1 - 1.5×IQR, Q3 + 1.5×IQR]
Q3 + 1.5IQR = 100 + 18.75
= 118.75
Since 150 > 118.75, it is an outlier
