Answer and Explanation:

Solution :

According to place value system,

Thousand Hundred Tens Ones

1) Number 8556

Thousand value of number = 8000

Hundred value of number = 500

[/tex]8000\times \frac{1}{10}=800 [/tex]

No, the digit in the hundreds place is not $\frac{1}{10}$ the value of the digit in the thousand place.

2) Number 6855

Thousand value of number = 6000

Hundred value of number = 800

$6000\times \frac{1}{10}=600$

No, the digit in the hundreds place is not $\frac{1}{10}$ the value of the digit in the thousand place.

3) Number 5568

Thousand value of number = 5000

Hundred value of number = 500

$5000\times \frac{1}{10}=500$

Yes, the digit in the hundreds place is $\frac{1}{10}$ the value of the digit in the thousand place.

4) Number 5656

Thousand value of number = 5000

Hundred value of number = 600

$5000\times \frac{1}{10}=500$

No, the digit in the hundreds place is not $\frac{1}{10}$ the value of the digit in the thousand place.

Therefore, Option 3 is correct.

step-by-step explanation:

Answer from: Quest

la parábola es el lugar

geométrico en el cual los puntos tienen una distancia idéntica, equidistantes,

de un punto denominado foco, f, y una recta denominada directriz

el radio vector de una

parábola es el segmento que existe entre un punto cualquiera y el foco.

por la ecuación se observa

que la parábola abre hacia la derecha, por lo cual podemos usar las siguientes fórmulas

la ecuación ordinaria de la

parábola es y^2 = 4px, donde p es la longitud desde el vértice de la parábola al

foco.

la fórmula de la directriz

es x + p = 0

resolviendo:

y^2-9x = 0

y^2 = 9x

4p = 9, entonces p = 9/4

entonces el foco tendrá la

coordenada f(9/4,0)

la directriz vendrá

expresada por

x + p = 0

x = -p

x = -9/4

el problema indica que la

ordenada es igual a 6, entonces

(6)^2=9x

x = 36/9

x = 4

entonces el punto al cual

hay que obtener la distancia será p(4,6)

calculando se tendrá: pf =

pf = 6,25 u

At wind speeds above 1000 centimeters per second (cm/sec), significant sand-moving events begin to occur. wind speeds below 1000 cm/sec deposit sand and wind speeds above 1000 cm/sec move sand to new locations. the cyclic nature of wind and moving sand determines the shape and location of large dunes. at a test site, the prevailing direction of the wind did not change noticeably. however, the velocity did change. fifty-nine wind speed readings gave an average velocity of x = 1075 cm/sec. based on long-term experience, σ can be assumed to be 245 cm/sec. (a) find a 95% confidence interval for the population mean wind speed at this site. (round your answers to the nearest whole number.) lower limit cm/sec upper limit cm/sec
