Answer:
Music Mart offers a better deal, given that the price of the guitar is $ 219 compared to $ 279.20 for Guitar Central.
Step-by-step explanation:
Since Tania is buying a guitar, and Guitar Central has 20% off coupons available, and has the guitar Tania wants for $ 349, while Music Mart has the guitar Tania wants for $ 419, but is offering a $ 200 rebate, to determine which is the better deal the following calculations must be performed:
Guitar Central
100 - 20 = 80
349 x 0.8 = X
279.20 = X
Music mart
419 - 200 = X
219 = X
Therefore, Music Mart offers a better deal, given that the price of the guitar is $ 219 compared to $ 279.20 for Guitar Central.
1 = x(2) - 2x - 3
1 = 2x + -2x + - 3
1 = (2x + -2x) + (-3)
1 = -3
1 - 1 = -3 -1
0 = -4

For skewed data displays, the median is often a better estimate of the center of distribution than the mean because the former is unaffected by large numbers.
<h3>What is mean?</h3>
Mean refers to the average of set of two or more numbers.
Mean of a set having 'n' numbers = 
<h3>What is median?</h3>
Median refers to the middle-most value of a list of numbers, arranged either in ascending or descending order.
Median = 
Now,
- Since it takes the average of all the values in the data set, the mean is the most widely used measure of central tendency.
- Because it is unaffected by exceptionally big numbers, the median performs better than the mean when analyzing data from skewed distributions.
Hence, For skewed data displays, the median is often a better estimate of the center of distribution than the mean.

Answer:
x = -1 and y = 1
Step-by-step explanation:
5x + 2y = -3 . . . . . . . (i)
x + 5y = 4 . . . . . . . (ii)
- Finding x in terms of y from eq. (ii) :-
x + 5y = 4
x = 4 - 5y
- Placing this value of x in eq. (i) :-
5(4 - 5y) + 2y = -3
20 - 25y + 2y = -3
-23y = - 23
<u>y = 1</u>
- Placing the value of y in eq. (i)
5x + 2(1) = -3
5x + 2 = -3
5x = - 5
<u>x = -1</u>
