Answer:
Option D
Step-by-step explanation:
The null hypothesis: ∪ = 0; they do not grow after conversation
the alternative hypothesis : ∪ ≠ 0; they grow after conversation
Based on the question asked and the results given which is:
Based on the t-test statistic and p-value, researchers found moderate evidence against the null hypothesis. Give the final statement of the hypothesis test.
we can then draw a conclusion that: There is not enough evidence to conclude the mean difference in the height of the plants between the conversion and control groups is 0
Answer:
The answer is 390 × pi.
Step-by-step explanation:
Big cone:
V = 1/3 x pi x r^2 x h
= 1/3 x 3.14 x 9^2 x 15
= 1272.3 cubic inches
Small cone:
V = 1/3 x pi x r^2 x h
= 1/3 x 3.14 x 3^2 x 5
= 47.1 cubic inches
1272.3 - 47.1 = 1225.2 cubic inches
1272/3.14 ≈ 390
The answer is 390 × pi.
Answer:
The answer to your question is 8 h
Step-by-step explanation:
Data
length of the ladder = 200 cm
distance between each rung = 20 cm
rate = 10 cm/h
fifth rung = ?
Process
1.- Calculate the total distance the tide must rise
distance = 20 cm x 4
= 80 cm because the first rung touches the water
2.- Calculate the time
rate = distance / time
-Solve for time
time = distance / rate
-Substitution
time = 80 cm / 10cm/h
-result
time = 8 h
12x50=600 so 60 left
15x50=750 so 60 left
so the administration fee is 60
