**Answer:**

x = 0

**Step-by-step explanation:**

3(x - 2) + 15= -3(x - 3)

3x - 6 + 15 = -3x + 9

3x + 9 = -3x + 9

3x + 3x = 9 - 9

6x = 0

x = 0

**Answer:**

1000

**Step-by-step explanation:**

4 times 25 =100 add anther 0 and it will be 1000

The **rate** of the current is 6 mile/hour.

<h3>

**What does a rate mean ?**</h3>

In this context, the rate is tantamount to** speed o velocity** in a linear motion. The S.I unit will be **mile per hour.**

Given that a boat takes 10 hours to sail a distance of 100 nautical miles with the current. The rate at which the boat move will be

The rate R1 = 100/10

**R1 = 10 mile/hour**

And when it moves against the current, it takes the boat 25 hours to sail the same distance. The rate at which the boat move will be

The rate R2 = 100/25

**R2 = 4 mile/hour**

The rate of the current R will be the **difference **between the two calculated rate. That is,

R = R1 - R2

R = 10 - 4

**R = 6 mile/hour**

Therefore, the **rate** of the current is 6 mile/hour.

**Answer: HOPE THIS HELPED YOU! :D ;P**

159lbs. (Pounds)

**Step-by-step explanation:**

V = kE

106 = k*120

k = 53/60

53/60 * 180 = 159lbs.

**Answer:**

**Step-by-step explanation:**

Given that;

Compressed Soil 2.85 2.66 3 2.82 2.76 2.81 2.78 3.08 2.94 2.86 3.08 2.82 2.78 2.98 3.00 2.78 2.96 2.90 3.18 3.16

Intermediate Soil 3.17 3.37 3.1 3.40 3.38 3.14 3.18 3.26 2.96 3.02 3.54 3.36 3.18 3.12 3.86 2.92 3.46 3.44 3.62 4.26

** Compressed soil intermediate soil**

**Mean **2.907 3.286

**SD **0.1414 0.2377

Here we have,

The pooled Standard deviation

So standard error for difference in population mean is

by inputting the values we get 0.0623

Degree of freedom for t is

df = 19 + 20 - 2 = 37,

so t-critical value is 2.715.

So required confidence interval for

will be

So required confidence interval is (0.2103 , 0.5483).
