Answer:
We cannot infer a cause and effect relationship because the treatments imposed were not blocked correctly.
Step-by-step explanation:
The treatments given to the groups given in the question where not assigned proper treatments to establish proper randomized block design.
Thus, we can say the conclusion is that we can't truly infer a cause and effect relationship as the blocks were not properly done.
Let x be the smaller number.
So the bigger number is x+19 (Their difference is 19)
Their sum: 53
Answer:
r = 55.2 cm
Step-by-step explanation:
the arc length is calculated as
arc = circumference × fraction of circle
= 2πr ×
( r is the radius )
given arc = 63.48π , then
2πr ×
= 63.48π ( cancel 2π on numerator/ denominator )
r ×
π = 63.48π ( divide both sides by π )
= 63.48 ( multiply both sides by 20 to clear the fraction )
23r = 1269.6 ( divide both sides by 23 )
r = 55.2 cm
