Answer: 1. -11=x 2. 24=x 3. x=-12 4. -7 5. x=7
Step-by-step explanation: The answer to first one can be calculated by seeing the - as a -1.
-5 = x - (-6)
-5=x+6
Then subtract 6 from both sides.
-5=x+6
-11=x
The answer to the second can be found simply by dividing both sides by 1.25.
- 30=1.25x
-30/1.25=1.25x/1.25
24=x
The third one can be solved by as we said before dividing both sides by -6.
-6x=72
-6x/-6=72/-6
x=-12
The fourth one can be found again by using division on both sides.
-4.9=0.7x
-4.9/0.7=0.7x/0.7
-7=x
Finally we solve the last one by again doing the same thing dividing both sides by 0.45.
3.15=0.45x
3.15/0.45=0.45x/0.45
7=x
Hope this helps!

Answer:
99% confidence interval for the soil water content is determined by
(0.19474, 0.26926)
Step-by-step explanation:
<u><em>Explanation</em></u>:-
Given mean of the sample = 23.2% = 0.232
Given standard deviation of the sample = 1.0% =0.01
Given sample size 'n' =4
Degrees of freedom = n-1 =4-1 =3
critical value = 0.01
99% confidence interval for the soil water content is determined by
( 0.232 -0.03726 , 0.232 +0.03726)
(0.19474, 0.26926)
<u><em>Final answer:</em></u>-
99% confidence interval for the soil water content is determined by
(0.19474, 0.26926)
