The initial cost is 189.69. It is marked up 30%.

By simple calculations, 

Final cost of the tablet computer = Initial price + 30% of marked price

= 189.69 + (30/100 x 189.69)

This gives us the net value of 245.7. Hence the price of the computer after it's been marked up will be 245.7

Answer:

246.60

Step-by-step explanation:

Cost of tablet computer = 189.69

Mark up = 30%

Profit = 30% × 189.69

         = 56.91

Final price after mark up = cost + profit

= 189.69 + 56.91

= 246.60

Ganezh [65]

Answer:

A)

Note that              

             

Lower Bound = X - z(alpha/2) * s / sqrt(n)              

Upper Bound = X + z(alpha/2) * s / sqrt(n)              

             

where              

alpha/2 = (1 - confidence level)/2 =    0.025          

X = sample mean =    1723.4          

z(alpha/2) = critical z for the confidence interval =    1.959963985          

s = sample standard deviation =    89.55083319          

n = sample size =    30          

             

Thus,              

             

Lower bound =    1691.355235          

Upper bound =    1755.444765          

             

Thus, the confidence interval is              

             

(   1691.355235   ,   1755.444765   ) [ANSWER]

Determine whether the sequence is geometric. If so, find the common ratio. 3.0, 6.0, 12.0, 24.0
Luba_88 [7]

Answer:

The sequence <u>is</u> geometric and the common ratio is 2

Step-by-step explanation:

A sequence is geometric if each term  (after the first one) is equal to the term before it times some constant number, called the 'common ratio'.

Examples:  1, 2, 4, 8, 16, ... has a common ratio of 2 because 2*2 = 4, and 4*2 = 8, and so on.

                 Also, -->  4, 2, 1, 1/2, 1/4/ 1/8, ... has a common ratio of 1/2 because

4 * 1/2 =  the next term 2, and 2 * 1/2 = the next trem 1/4, and son on.

In this case, 3 * 2 = 6

                    6 * 2 = 12

                    12 * 2 = 24

The sequence <u>is</u> geometric and the common ratio is 2

A publisher requires 2⁄3 of a page of advertisements for every 5 pages in a magazine. If a magazine has 98 pages, to the nearest
rjkz [21]

Let x be the number of pages of advertisements.

Write a proportion from the table:

\dfrac{2}{3} of a page of advertisment - 5 pages in a magazine

x pages of advertisment - 98 pages in a magazine,

then

\dfrac{\dfrac{2}{3}}{x}=\dfrac{5}{98}.

Find x:

x=\dfrac{\dfrac{2}{3}\cdot 98}{5}=\dfrac{196}{15}=13\dfrac{1}{13}.

Answer: 13 whole pages and \dfrac{1}{13} of 14th page are advertisments, so 14 pages contain advertisments.
