al dividir A entre 23 se obtuvo 247 de cociente y el residuo fue el maximo. hallar A a)5242 b)5436 c)5703 d)5332 solo esas 4 alt

yuradex [85]

Aplicando la división, hay que el valor de A es dado por:

c) 5703

Una división es representada por:

$\frac{a}{b} = c + \frac{r}{b}$

En que:

c es el cociente.

r es el residuo.

En este problema, $b = 23$ , y también:

Cociente de 247, o sea, $c = 247$ .

Residuo maximo, que es 22, o sea, $r = 22$ .

$\frac{a}{b} = c + \frac{r}{b}$

$\frac{A}{23} = 247 + \frac{22}{23}$

$A = 23(247) + 22 = 5703$

El valor de A es dado por:

c) 5703

Fill in each square with a digit 1-9, and fill in

iren [92.7K]

Answer:

532

Step-by-step explanation:

To make the right hand side as large as possible, the numerator must be as large as possible and the denominator must be as small as possible. But we can only use each digit once.

Through trial and error:

(9 × 8 + 4) / (1 − 6 ÷ 7) = 532

. A study was done on the proportion of cities that have private refuse collectors. The student wants the margin of error to be

ELEN [110]

Answer: 68

Step-by-step explanation:

As per given , we have

Margin of error : E= 0.10

Critical z-value for 90% confidence interval : $z_{\alpha/2}=1.645$

Since , the estimate of true proportion is unknown , then

The formula to find the sample size :-

$n=0.25(\dfrac{z_{\alpha/2}}{E})^2\\\\ n=0.25(\dfrac{1.645}{0.10})^2\\\\ n=67.650625\approx68$

The required minimum sample size= 68
