1 . What is the mean of the data set?
Answers
average= total number/number of objects or numbers
so the answer is 393, 399, 402,402,407, 410, 424, 425, 428 all added together then divided by 9
if we use a calculator to add them up we get 3690
then divide by 9
3690/9=410
410 is the mean
in the firs row there is 39 | 3 9 which means there are items 393 and 399,
to calculate sum i may write 393 + 399, or 3 + 9 + 39*2*10 which i find easier to calculate
sum = 3 + 9 + 2 + 2 + 7 + 0 + 4 + 5 + 8 + (2*39 + 3*40 + 1*41 + 3*42)*10 = 40 + (78+120+41+126)*10 = 40 + 3650 = 3690
mean = sum / number of items = 3690 / 9 = 410

Answer:
a) Which item’s price was reduced by more, and by how many dollars more was it reduced?
The DVD player's price was reduced more by $3.82 than the stereo tuner's price.
b) Round all dollar values to the nearest cent.
Rounding $3.82 dollars to the nearest cents
$1 = 100 cents
$3.82 =
3.82 × 100 cents
= 382 cents
The DVD player's price was reduced by 382 cents more than the stereo tuner's price
Step-by-step explanation:
Lets day the original price of the DVD player was $100
We are told the price was marked down to 36%
36% of $100 = $36
$100 - $36 = $64
We are told the DVD cost $41.60 after the markdown.
Original cost of DVD =
$41.60/$64 × 100 = $65
Lets the original price of the Stereo player was $100
We are told the price was marked down to 22%
22% of $100 = $22
$100 - $22 = $78
We are told the DVD cost $69.42 after the markdown.
Original cost of Stereo =
$69.42/$78 × 100 = $89
DVD = $65 - $41.60 = $23.40 less
Stereo = $89 - 69.42 = $19.58 less
Difference between the DVD and the Stereo is
$23.40 - $19.58 = $3.82
Therefore,the DVD player's price was reduced by $3.82 more than the stereo tuner's price
Rounding $3.82 dollars to the nearest cents
$1 = 100 cents
$3.82 =
3.82 × 100 cents
= 382 cents

Your Answer:
C.) 5(x² - 8)
Step-by-step explanation:
If you were to redistribute the 5 in 5(x² - 8), you would get 5x² - 40, which was what you initially started off with.
Hope this helps y'all :)
