The graph shows the linear relationship between the height of a plant (in centimeters) and the time (in weeks) that the plant ha
s been growing. Which statements are correct? Check all that apply. The rate of change is 4. The rate of change is 1. The rate of change is . The plant grows 4 cm in 1 week. The plant grows 1 cm in 4 weeks

I found a graph with the same problem, so I guess this is the graph to be based on. To find the rate, just determine the slope between any two points along the line. Suppose these points are: (30,10) and (50,20).
Slope = (20 - 10)/(50 - 30) = 1/2
<em>The correct answer should be: the rate of change is 1 cm per 2 weeks, or 1/2.</em>
Slope = (20 - 10)/(50 - 30) = 1/2
<em>The correct answer should be: the rate of change is 1 cm per 2 weeks, or 1/2.</em>

Step-by-step explanation:
Mod of any number represents the absolute value of the number.
Therefore, = 2.25
Now we can arrange these numbers in ascending order.
-2.25 < -1.25 < 0.75 < 1.25 < 1.75 < 2.25
Therefore,
Answer:
The probability that they will both be on time is 12/25.
Step-by-step explanation:
John is late 20% of the time.
So, he is prompt 80% of the time.
Ted is late 40% of the time.
So, he is prompt 60% of the time.
Since, both the events are independent,
p(John be on time ∩ Ted be on time) = p(John be on time) × p(Ted be on time)
×
= 0.80 × 0.60
= 0.48 or 48%
Hence, the probability that they will both be on time is 12/25.
