Domain (negative infinity to positive infinity)
y - intercept = (0,
)
Answer:rational
Step-by-step explanation:
When reflecting something across the y axis, the x point becomes of the opposite parity (for example, when reflecting (1,2) across the y axis, the result would be (-1,2)). In this case, we can start by doing this for each of the individual points.
J (1,4) becomes (-1,4) when reflected across the y axis
R (2,1) becomes (-2,1) when reflected across the y axis
A (3,5) becomes (-3,5) when reflected across the y axis
So, I think that your mistake was that you thought that reflecting across the y axis meant changing the y coordinate. That being said, the correct answer is A.
Answer:
The data is skewed left
Less than
Median is 22
mean is 20.2
Step-by-step explanation:
<u>median: 15,16,18,19</u>,22,22,<u>22,22,23,23</u>
mean: 15+16+18+19+(22x4)+(23x2)=
31+37+88+46=
68+134=202÷10=20.2
Answer:
52 mph
Step-by-step explanation:
1 hour is 60 minutes, 4 times the time period given in the problem. If the speed is constant, the car will travel 4 times the distance in 4 times the time.
... 4 · (13 miles) = 52 miles
The car will travel 52 miles in 1 hour, so its speed is 52 mi/h.
