Given:
and .
To find:
The relationship between the ratios.
Solution:
We have, two ratios in the fraction form.
and
First ratio =
=
= (Cancel out the common factors)
First ratio = Second ratio
Since, the both ratios are equal to each other, therefore, the given ratios are equivalent ratios.

Answer:
150 kL glutinous rice
300 kL ordinary rice
Step-by-step explanation:
Each half of the property is 3 ha/2 = 1.5 ha.
For the transplanted glutinous rice, John needs ...
(100 kL/ha)·(1.50 ha) = 150 kL
For the broadcast ordinary rice, John needs ...
(200 kL/ha)·(1.50 ha) = 300 kL
Answer:
Step-by-step explanation:
From the attached photo
mean = 15.76
Standard deviation = 1.66
c) We want to determine a 90% confidence interval for the mean growth of pea plants
For a confidence level of 90%, the corresponding z value is 1.645. This is determined from the normal distribution table.
We will apply the formula
Confidence interval
= mean ± z ×standard deviation/√n
It becomes
15.76 ± 1.645 × 1.66/√7
= 15.76 ± 1.645 × 0.63
= 15.76 ± 1.04
The lower end of the confidence interval is 15.76 - 1.04 =14.72
The upper end of the confidence interval is 15.76 + 1.04 =16.8
