Step-by-step explanation:

Table 1

⇒ Side length : Perimeter = 1 : 4

⇒ Perimeter : Side length = 4 : 1

Table 2

⇒ Radius : Diameter = 1 : 2

⇒ Diameter : Radius = 2 : 1

Table 3

⇒ Number of people : Number of tables = 5 : 1

⇒ Number of tables : Number of people = 1 : 5

The owner of a small store buys coats for $55.00 each. Answer parts a and b. a. He sells the coats for $77.00 each. What perce

lapo4ka [179]

Th owner must buy 7 Jackets

Step-by-step explanation:

a. Purchase price=$55 , Sell Price= $77

Sell Price = $55+$22

= Purchase price + 40*55/100

=Purchase price + 40% of Purchase price

=140% of purchase price

b. Purchase Price=$35

Sell price=140%of $35

=140*$35/100

=$49

Number of Jackets required for the total sale to be $340 = $340/$49

=6.94

So We get the result by rounding off because Jackets cannot be in fraction, which is 7

Ahat [919]

To find out area of circle bit u do (pi x r^2) /4

(3 x 6^2)/4
(3x 36) / 4
108/4 = 27

So area of circle bit is 27

For square you do:
6x6 = 36

ANSWER:

36+27 = 63

The answer is 63m^3

g In 2013, the Pew Research Foundation reported that 43% of U.S. adults report that they live with one or more chronic condition

SOVA2 [1]

Answer:

We are 95% confident that the true proportion of U.S. adults who live with one or more chronic conditions is between 39.7% and 46.33%

Step-by-step explanation:

From the question we are told that

The sample proportion is $\r p = 43\% = 0.43$

The standard error is $SE = 0.017$

Given that the confidence level is 95% then the level of significance is mathematically represented as

$\alpha = (100-95)\%$

=> $\alpha = 0.05$

Generally from the normal distribution table the critical value of $\frac{\alpha }{2}$ is

$Z_{\frac{\alpha }{2} } = 1.96$

Generally the margin of error is mathematically represented as

$E = Z_{\frac{\alpha }{2} } * SE$

=> $E = 1.96 * 0.017$

=> $E = 0.03332$

Generally 95% confidence interval is mathematically represented as

$\r p -E < p < \r p +E$

=> $0.43 -0.03332 < p < 0.43 + 0.03332$

=> $0.39668 < p < 0.46332$

Converting to percentage

$(0.39668 * 100)< p < (0.46332*100)$

$39.7\% < p < 46.33 \%$
