A farmer wishes to determine which of two brands of baby pig pellets, Kent or Moormans, produces better weight gains. Two of his sows each give birth to litters of 10 pigs on the same day, so he decides to give the baby pigs in litter A only Kent pellets, while the pigs in litter B will get only Moormans pellets. After four weeks, the average weight gain for pigs in litter A is greater than the average weight gain for pigs in litter B. The feed they get is not the only factor affecting the rate at which pigs gain weight. Genetic differences also affect weight gain. It is likely that the pigs in litter A are genetically different from the pigs in litter B since the two litters have different mothers.
What experimental design technique could the farmer use to take into account the genetic differences?
a. Placebo
b. Blocking
c. Probability sampling
d. Double blinding
e. Observational study
Answer:
Option d (Double blinding) would be the appropriate choice.
Explanation:
A double-blind research paper would be one in which although neither group members nor even the researchers understand whose been receiving a specific intervention. This methodology has been used to protect participants throughout the research findings, which are especially beneficial throughout the prevention of bias reducing the power of personality traits or perhaps the placebo impacts.Certain other preferences are not related to just the illustration in question. So the above alternative seems to be the correct one.

Using related equations, what is the solution of this equation ? List the related equations
7w = 92
Don’t use me for points
Step-by-step explanation:
Divide both sides of the equation by the same term
7w = 92
[tex]\frac{7w}{7} =\frac{97}{7}[/tex]
Simplify
Cancel terms that are in both the numerator and denominator
[tex]w =\frac{92}{7}[/tex]
Answer:
[tex]w= \frac{92}{7}[/tex]

Step-by-step explanation:
Sydney is 8 years less than twice Steven’s age what is the algebraic expression.
Answer:
2s - 8
Step-by-step explanation:
sydney is 8 years LESS than TWICE stevens age.
let’s turn stevens age into a variable... s. the variable will be s. so sydney’s age is 8 years less than TWICE stevens age. so lets start with the twice stevens age..
since there is an easy way to make that part of the equation, let’s just put it as 2s. then we have to take sydney’s age as 8 years less than twice stevens. so that would be - 8. so if you add those 2 parts together, you get the equation 2s - 8.
So overall the proper equation will be 2s - 8.
A ramp is propped against the back of a truck. There is a 30 degree
angle between the ramp and the horizontal pavement

The trigonometric function gives the ratio of different sides of a right-angle triangle. The length of the ramp is equal to 10ft.
What are Trigonometric functions?The trigonometric function gives the ratio of different sides of a right-angle triangle.
[tex]\rm Sin \theta=\dfrac{Perpendicular}{Hypotenuse}\\\\\\Cos \theta=\dfrac{Base}{Hypotenuse}\\\\\\Tan \theta=\dfrac{Perpendicular}{Base}[/tex]
where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite to the 90° angle.
The length of the ramp is,
Cos(θ) = Base/Hypotenuse
Cos(30°) = 9ft /The length of the ramp
The length of the ramp = 9ft/Cos(30°)
Length of the ramp = 10.3923 ft ≈ 10ft
Hence, the length of the ramp is equal to 10ft.

Write the following ratio as a reduced fraction. Simplify your answer when possible: 22 to 42
Answer:
11 / 21
Step-by-step explanation:
The ratio 22 to 42 can be written as: 22 : 42, and in fraction form as:
22 / 42 in this fraction we can cancel a common factor of 2 from numerator and denominator, leaving us with the reduced fraction:
2 * 11 / (2 *21) = 11 / 21

B. u(n) = 6 + 3n, where n = 1, 2, 3, 4, . . .
C. u(n) = 3 + n, where n = 1, 2, 3, 4 . . .
D. u(n) = 3n, where n = 1, 2, 3, 4, . . .
Answer:
B.
Step-by-step explanation:
The common difference is + 3 so we have an arithmetic sequence.
u(n) = a1 + d(n - 1)
= 9 + 3(n - 1)
= 9 + 3n - 3
= 6 + 3n.
