Answer:
4. The number of episodes of pain.
Step-by-step explanation:
A typical experiment, usually has a response and explanatory variable. A response variable is the major problem we seek to resolve in the experiment. The explanatory variable, on the other hand, provides reasons that would explain the response variable.
In the question asked, we are trying to understand if hydroxyurea can reduce the pain suffered by sickle cell sufferers. The experiment is trying to resolve the problem of pain suffered by sickle cell sufferers. Therefore, this is the response variable.
The explanatory variable would be the drug hydroxyurea which would be used to measure and explain the response variable- the number of episodes of pain.

surely you know how much that is.
Answer:
slope = -
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - x + ← is in slope- intercept form
with slope m = -
Parallel lines have equal slopes, thus
m = - ← is slope of parallel line

Answer:
78%
Step-by-step explanation:
Given the information, we can write:
P(cook) = 52%
P(shop) = 54%
P(cook and shop) = 28%
Now, we need to find P(cook or shop).
We need probability formula for general addition rule, which is:
P(A or B) = P(A) + P(B) - P(A and B)
We can take "cooking" and Event "A" and "shopping" as Event "B".
Thus, we write:
P(A or B) = P(A) + P(B) - P(A and B)
P(A or B) = 0.52 + 0.54 - 0.28
P(A or B) = 0.78
Which is 78%
