Answer:
i) Assigning women at random ensures that the two groups are comparable.
iv) A control group provides a baseline for comparisons to determine treatment effects.
Step-by-step explanation:
(a)
It is pertinent that there two comparable groups. In light of the fact that it will help in making better decisions since there will be some people who have blood pressure as a result of uncontrolled physical characteristics such as anger, positive attitude, lower blood pressure. etc Thus, there is a need to consider two equivalent groups.
(b)
A control group is used as a benchmark for determining the cause and effect of a treatment on a given experimental group. This may be in regard to the social aspect of meeting other individuals involved that make up the physical changes.
Step 2 should be the answer!!
In a function f(x):
set of all the values that x can take is called the domain of the function.
Set of all the values that f(x) (or y) can take is called the range of the function.
Range can have either finite or infinite number of values depending on the function its domain.
For example, f(x) = x^2
can have infinite number of values in range.
whereas :
f(x) = [x] , 0<x<10
where [x] is the greatest integer function,
has finite number of values in its range.
Answer:
250 Hamburgers
Step-by-step explanation:
575 is total
Hamburger is x
Cheesburgers is (x-75) as it is 75 less than the number of hamburgers
x + (x-75) = 575
2x -75 = 575
2x = 500
x = 250

Answer:
C and E are correct
Step-by-step explanation:
We simply substitute the value of x to see if we can get y for each of the equations
A. y = -3x
2 is not -3(6)
This is wrong
B. y = -3/2x + 6
-3/2x + 6 = -3/12 + 6
This cannot be equal to 2 so this is wrong also
c. y = -1/6x + 3
y = -1/6(6) + 3
= -1 + 3 = 2
This is correct
d. y = 2/3x - 1
This is wrong
2/3(6) - 1 cannot be 2
e. y = 1/2x - 1
2 = 1/2(6) -1
This is correct
F. y = 4(6) - 2 = 24-2 = 22
