3/10+ 2/5
= 3/10+ 4/10 (common denominator is 10)
= 7/10
The final answer is 7/10~
Answer:
<em>The correct option will be: (b) 7 feet.</em>
Step-by-step explanation:
Suppose, the length of the garden is
feet.
As the <u>shape of the garden is like a square, then the area of the garden</u> will be:
feet²
Given that, the <u>area is 52 square feet</u>. So, the equation will be.......

So, the approximate length of the garden will be 7 feet.

Answer: A.

Step-by-step explanation:
Null hypothesis
: A statement describing population parameters as per the objective of the study. It usually takes "≤,≥,=" signs.
Alternative hypothesis
: A statement describing population parameters as per the objective of the study. It usually takes ">, <, ≠" signs.
Let p be the proportion of screens that will be rejected.
12 percent of the screens manufactured using a previous process were rejected at the final inspection.
(i.e. p= 0.12)
Objective of the study = whether the new process<em> reduces </em>the population proportion of screens that will be rejected
i.e. p< 0.12
So, the appropriate hypotheses to investigate whether the new process reduces the population proportion of screens that will be rejected:

Answer with Step-by-step explanation:
The basic water balance dictates that "Amount of water flowing into the basin should be equal to the amount of water flowing out of it".
Mathematically

where
P = precipitation
I = Infiltration losses in the basin
E = Evapotranspiration
Q = is outflow from the basin
Applying the given values we get

Part b)
From the above equation we get

The evaporation in cubic meters per year is
