Answer:

Step-by-step explanation:
is the least steeped graph
- The greater the slope, the steeper the line.
- Also you use the absolute values of the slopes when determining the steepness.
- So here it would be:

- Now, arrange them from least to greatest:

As you can see,
is the smallest number/slope.
Hope this helps!
<u>Answer-</u>
<em>In </em><em>25.15%</em><em> cases their response times is over 30 minutes.</em>
<u>Solution-</u>
Hint- Calculating the z-score (how much standard deviations away from the mean) and then getting the corresponding probability value from normal distribution table we can get solution.
Applying the formula for Z-score,

Here,
X = score = 30,
μ = mean = 22,
σ = standard deviation = 11.9
Putting the values,


(Subtracted from 1 as the values of area to the left of the Z score is given in table, but we need the area right to Z score as response times more than 30 minutes is asked)
Answer: The answer is the 3rd one - Positive, linear association
Step-by-step explanation:
Using an exponential function, it is found that the multiplier used to predict the amount of medication remaining 2 hours after the peak level is of 0.6889.
<h3>What is an exponential function?</h3>
A decaying exponential function is modeled by:

In which:
- A(0) is the initial value.
- r is the decay rate, as a decimal.
In this problem, we have that the decay rate is of r = 0.17, hence:

After 2 hours, the multiplier is given by:

Just distribute the 3. 3(x + 4y) = 3x + 12y
3x + 12y is the answer.
