The errors in predicting hurricane tracks are given in nautical miles. A statutory mile is 0.86898 nautical mile. Most people li

ving on the Gulf Coast of the United States would prefer to know the prediction errors in statutory miles rather than nautical miles. Explain why converting the errors to miles would not change the correlation between Prediction Error and Year.

Answer:

The prediction error is calculated as the difference between the actual value and the predicted value of the hurricane tracks.

the actual and the predicted value can then be converted into stationary miles

Step-by-step explanation:

The prediction error is calculated as the difference between the actual value and the predicted value of the hurricane tracks.

Now,

both the values i.e the actual and the predicted value can then be converted into stationary miles using the conversion factor without changing the association with the year,

Hence,

it will do the same for the Prediction error.

Hello!

<em>According to the diagram, your answer is</em> <em>D.) Some Elephants have tusks</em>

If the entire circle labeled "Elephants" was inside the circle labeled "Animals With Tusks," it would be A, but that is not the case. only part of it is inside. so D is the correct answer.

I hope this helps, and have a nice day!

Resuelve las siguientes ecuaciones: -x^2 - x =0 -X^2 + 12x = 0 3X^2 - 9x = 0 X^2 - 2x - 3 = 0
vaieri [72.5K]

Responder:

<em>a) 1 </em>

<em>b) 12 </em>

<em>c) 3 </em>

<em>d) -1 y 3 </em>

Explicación paso a paso:

Dadas las siguientes ecuaciones;

a) x²-x =0

x² = 0+x

x² = x

x = 1

b) -x²+12x = 0

-x² = -12x

x² = 12x

x = 12

c) 3x² - 9x = 0

Suma 9x a ambos lados

3x²-9x+9x = 0+9x

3x² = 9x

3x = 9

x = 9/3

x = 3

d) x²-2x-3 = 0

x²-3x+x-3 = 0

x(x-3)+1(x-3) = 0

(x+1)(x-3) = 0

x+1 = 0 y x-3 = 0

x = -1 y 3

junior rides his trucycle off a level porch. If he left the porch at a speed of 4 m/s and landed a horizontal distance of 2.5m f
WITCHER [35]

Answer:

the height of the porch is H=1.91 m

Step-by-step explanation:

neglecting friction and assuming that the porch is horizontal, then the horizontal speed is v₀= 4 m/s and it does not change , thus he hits the base at

t= L/v₀ , L= horizontal distance

then for vertical motion , since the vertical velocity vy is 0 , the initial height is H ( the height of the porche)  and the final height hf is 0 , we have

hf = H + vy*t - 1/2*g*t²

0 = H + 0 -1/2*g*t²

H = 1/2*g*t² = 1/2*g*(L/v₀)²

replacing values with g= gravity = 9.8 m/s²

H = 1/2*g*(L/v₀)² = 1/2*9.8 m/s² *( 2.5 m/ 4 m/s)² = 1.91 m

therefore the height of the porch is H=1.91 m
