some students want to order shirts with their school logo.onr company charges $9.00 per shirt plus a setup fee for $43.another c

Amanda [17]

Let's let x be the number of t-shirts.

So the first company charges $43 plus $9 per shirt. For x shirts, the cost is the base fee plus 9 times x, or $C=9x+43$ .

The second company charges a $58 fee plus $8 per shift. The cost is $C=8x+58$ .

Now, we want to find which fee is less when we are buying 20 shirts. We plug in 20 for x.

The first company charges $C=9(20)+43=223$ .

The second company charges $C=8(20)+58=218$ .

The costs are VERY close, but the second company ultimately charges less.

Setler79 [48]

Answer:

a) yes

b) ( 0.0280 , 0.1720 )

c) No

Step-by-step explanation:

A) Determine if the sample sizes are large enough

where :

ages between ( 18 to 29 )

p1 = 0.48 ,

n1 = 178 , ∴ n1 P1 = 85.44 also n1 ( 1 - p1 ) = 92.56

ages between ( 50 to 64 )

P2 = 0.03 ,

n2 = 427 ∴ n2p2 = 12.81 also n2( 1 -p2 ) = 414.19

since all the values ae above 10 we can conclude that the sample sizes are large enough 

answer = yes 

B) Estimate the difference in the proportion of adult Americans aged 18 to 29

= ( 0.0280 , 0.1720 )

attached below is the detailed solution

C) zero is not included in the interval

For Each Data Set, Determine the median, the first and third Quartiles, and the interquartile Range.

stiks02 [169]

1. First of all arrange the data set in either ascending or descending order.
12, 19, 24, 26, 31, 38, 53. N = 7 (number of data items)
Median position = 1/2(N + 1)th item = 1/2(7 + 1)th item = 1/2(8)th item = 4th item = 26
First quatile = 1/4(N + 1)th item = 1/4(7 + 1)th item = 1/4(8)th item = 2nd item = 19
Third quatile = 3/4(N + 1)th item = 3/4(7 + 1)th item = 3/4(8)th item = 6th item = 38
Interquatile range = Third quartile - first quatile = 38 - 19 = 19
