The p-value is used to decide whether to reject or fail to reject the null hypothesis

Step-by-step explanation:

The p-value is used to make a conclusion in significance testing.

Where the p-value is lower than the significance value adopted ∝, you reject the null hypothesis H₀. In such a case, p-vale<∝⇒reject H₀⇒accept Hₐ.

Where the p-value is greater than or equal to the significant level ∝, you fail to reject the null hypothesis H₀, to mean p-value≥∝⇒fail to reject  H₀

Eqyivalent expresion to 3√m^2n^5
Irina18 [472]
The first step to solving this expression is to factor out the perfect cube
\sqrt[3]{m^{2}  n^{3} X n^{2}   }
The root of a product is equal to the product of the roots of each factor. This will make the expression look like the following:
\sqrt[3]{ n^{3} } \sqrt[3]{ m^{2} n^{2}  }
Finally,, reduce the index of the radical and exponent with 3
n\sqrt[3]{ m^{2} n^{2}  }
This means that the correct answer to your question is n\sqrt[3]{ m^{2} n^{2} } .

A plane flying over the ocean is on course to land on an aircraft carrier. The diagonal distance between the plane and the aircr
fomenos

Answer:

the plane's current height above the ocean is 3.42 miles

Step-by-step explanation:

Given that the diagonal distance between the plane and the aircraft carrier is 10 miles.

What we need to find is the vertical distance between the plane and the aircraft carrier which is the plane's current height above the ocean. This can be gotten using sine rule.  

For sine rule, you need a side and its opposite angle. For this question the triangle formed is a right angle triangle with diagonal distance, vertical distance and horizontal distance.

let a = diagonal distance = 10 miles

let the opposite angle to the diagonal distance be A = 90° (right angle)

let the vertical distance = b

let the opposite angle to the vertical distance be B = 20°

Sine rule states that    \frac{a}{sin(A)}  =  \frac{b}{sin(B)}

∴   \frac{10}{sin(90)}  =  \frac{b}{sin(20)}

b  =  sin(20)\frac{10}{sin(90)}

b  =  0.342*\frac{10}{1}

⇒ b = 3.42 miles

Therefore the plane's current height above the ocean is 3.42 miles
