Its 4.0 sq inches. there are online calculators btw

j = # of jars
b = # of buckets
y = total # of rocks
2j + 3b = y (2 rocks per jar, 3 rocks per bucket)
Because Joy has 3 jars you can plug 3 in for "j", and because she has 4 buckets you can plug in 4 for "b"
2(3) + 3(4) = y
6 + 12 = y
18 = y
Answer:
C = 97.20
Step-by-step explanation:
Given that C varies as r² then the equation relating them is
C = kr² ← k is the constant of variation
To find k use the condition C = 202.80 when r = 2.6
k = = = 30
C = 30r² ← equation of variation
When r = 1.8, then
C = 30 × 1.8² = 97.20
Answer:
The statistical analysis that is appropriate for her design is : one way within groups analysis of variance or ANOVA.
Step-by-step explanation:
The statistical analysis that is appropriate for her design is : one way within groups analysis of variance or ANOVA.
In ANOVA, the researchers can reduce the within-groups variability, by keeping the same number of participants in each group.
