T-Shirts & More Print Shop will print any image on a coffee mug for a cost of $2 per mug and a one-time charge of $12 to set

viktelen [127]

T-Shirts $ More Shop: Final cost = 2m + 12

m = mug

You Say It, We Print It: Final Cost = 5m

If you buy 5 mugs from both place:

2 * 5 = 10

10 + 12 = 22

$22 for T-Shirts & More

5 * 5 = $25

$25 from You Say It, We Print It

D. T-Shirts & More is the better buy if you buy more than 4 mugs.

One sample has a mean of and a second sample has a mean of . The two samples are combined into a single set of scores. What is t

Murrr4er [49]

Answer:

a) For this case we can use the definition of weighted average given by:

$M = \frac{ \bar X_1 n_1 + \bar X_2 n_2}{n_1 +n_2}$

And if we replace the values given we have:

$M = \frac{8*4 + 16*4}{4+4}= 12$

b) $M = \frac{8*3 + 16*5}{3+5}= 13$

c) $M = \frac{8*5 + 16*3}{5+3}= 11$

Step-by-step explanation:

Assuming the following question: "One sample has a mean of M=8 and a second sample has a mean of M=16 . The two samples are combined into a single set of scores.

a) What is the mean for the combined set if both of the original samples have n=4 scores "

For this case we can use the definition of weighted average given by:

$M = \frac{ \bar X_1 n_1 + \bar X_2 n_2}{n_1 +n_2}$

And if we replace the values given we have:

$M = \frac{8*4 + 16*4}{4+4}= 12$

b) what is the mean for the combined set if the first sample has n=3 and the second sample has n=5

Using the definition we have:

$M = \frac{8*3 + 16*5}{3+5}= 13$

c) what is the mean for the combined set if the first sample has n=5 and the second sample has n=3

Using the definition we have:

$M = \frac{8*5 + 16*3}{5+3}= 11$

Artyom0805 [142]

Answer:

the value of x-1/x is given down

Step-by-step explanation:

=(x+1/x)²=x²+1/x²+2

=(5)²=x²+1/x²+2

=x²+1/x²=25-2

=x²+1/x²=23 this is the answer

if u ask there how 25 came means there (5)² is that u should multiply 5×5 and u will get 25bas the answer
