The most common way to raise the pH of soil is to add pulverized limestone to the soil. Limestone acts as a soil acid neutralizer and consists of either calcium and magnesium carbonate or calcium carbonate. These are called dolomitic limestone and calcitic limestone respectively.
Answer:
3.14
Step-by-step explanation:
Given that:
Mean weight (m) = 79 ounces
Population standard deviation (s) = 13.1
Sample size = 47
Maximal margin of error associated with 90% confidence interval.
The margin of error is given by:
Zcritical * (standard deviation / sqrt(sample size)
Z critical at 90% confidence interval = 1.645
Hence,
Zcritical * (standard deviation / sqrt(sample size)
1.645 * 13.1 / sqrt(47)
1.645 * (13.1 / 6.8556546)
1.645 * 1.9108313
Hence, the margin of error is :
3.1433174885
= 3.14

Answer:
X=9/10
Step-by-step explanation:
5x+1=-5x+10
5x+5x= 10-1
10x=9
x=9/10
The values of the variables x, y and z are; 9, 81 and 6 respectively
<h3>Rhombus Diagonals</h3>
According to the question;
- All sides of the Rhombus are equal.
Hence, the Diagonals of the Rhombus are perpendicular bisectors of each other.
Therefore,
Angles 1, 2 and 3 are all equal to 90°, so that we have;
x = 9°
y = 81°
z = 6°
