What is the best way to convert metric units (I'm really bad at this...)
Vladimir [108]
Necesitas reconocer los múltiplos u submúltiplos del sistema métrico decimal si son lineales por cada nivel que avanzas multiplicas o divides con el 10
siempre y cuando la unidad de medida es el metro ese queda al centro.
Km Hm Dam m dm cm mm yo los ubico en escalera el metro queda al centro y de cualquier lugar que te posicionas,buscas a donde quieres convertir y revisas si vas a la derecha multiplicas por 10 o si vas a la izquierda divides entre 10 siempre y cuando sea un lugar a donde te vas a mover si son dos lugares es con el 100 por que 10x10 es 100 y si son tres lugares es con el 1000 porque es 10x10x10.
ejemplo 2000m convertirlos a Hm= 20 Hm dividí 2000 entre 100 porque me moví 2 lugares a la izquierda  otro ejem. 100 Dam convertirlos a cm=100000 porque 100x 1000 por que avance 3 lugares a la derecha

Find the approximate value of each trigonometric function.
vodka [1.7K]

Answer:

<u>Given</u>

  • tanθ = 3.454
  • θ is in the III quadrant

We know in the III quadrant both sine and cosine are negative.

<u>Use the following identities to get values of sinθ and cos θ</u>

  • sinθ = - tanθ/√(1 +tan²θ)
  • cosθ = - 1/√(1 +tan²θ)

<u>Substitute the value of tanθ and find sine and cosine:</u>

  • sinθ = - 3.454/√(1 + 3.454²) = - 0.961
  • cosθ = - 1/√(1 + 3.454²) = - 0.278

laila [671]

Answer: 756

Step-by-step explanation:

Given : The proportion of adults over 50 never graduated from high school.  = 0.23

Margin of error : E=0.03

Significance level : \alpha=1-0.95=0.05

Critical value : z_{\alpha/2}=1.96

The formula to find the sample size is given by:_

n=p(1-p)(\dfrac{z_{\alpha/2}\ }{E})^2

i.e. n=(0.23)(0.77)(\dfrac{(1.96)}{0.03})^2=755.941511111approx756

Hence, the required minimum sample size = 756
