Answer:
Yes
Step-by-step explanation:
7 x 7 = 49
Answer: 13
Step-by-step explanation:
Let the number that in thinking of be represented by x.
I multiply by 11 and add 22 will give the same answer as multiplying by 4 and adding 113. This.csn be firmed into an equation as:
(11 × x) + 22 = (4 × x) + 113
11x + 22 = 4x + 113
Collect like terms
11x - 4x = 113 - 22
7x = 91
x = 91/7
x = 13.
The number is 13
Answer:
C
Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (4, 9) and (x₂, y₂ ) = (12, 20)
m =
=
→ C
To easily find the slope from standard form (Ax + By = C) use -A/B
1. m = -5/3
2. m = -3/5
perpendicular slopes are negative reciprocals, which these are not
parallel slopes are exactly the same, which these are also not
so, these equations are neither parallel nor perpendicular
Solution: Which of the following is not an example of replication?
Answer: Replication is the repetition of an experimental condition so that the variability associated with the phenomenon can be estimated. Therefore option A is not an example of replication
A. Conducting different experiments on the same groups
