Let y represent the original price of a game.
<span>Ella purchased a game that was on sale 12% off which means that the new price of the game is 88% of the original price, so:
</span>
Next, t<span>he sales tax in her county is 6%, which means that the the now price is 106% to the original price, so:
</span>
. As a result, the final cost can represent under the form of 0.9328y. Hope it help!
Step-by-step explanation:
(-23) x 93 = - 2139
(- 16 ) x (- 30) = 480
14 x (- 12) = - 168

Kindly check explanation
Step-by-step explanation:
Given the data:
Temperature (degrees Celsius) : 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30
Percent heat loss from beak : 35 36 38 28 41 43 55 46 39 54 45 58 60 56 62 67
Using an online regression calculator ; the regression equation obtained is :
ŷ = 2.0927X + 0.6029
X = independent variable
Y = predicted variable
2.0927 = slope
0.6029 = intercept
B.) temperature = 25
ŷ = 2.0927(25) + 0.6029
= 52.9204
C.) the explained variance is the value of the coefficient of determination (R²) which is the square of the correlation Coefficient
0.8785² = 0.7718
D.) the correlation Coefficient r is 0.8785 using the Coefficient of regression calculator
Rearranging the data set in ascending order:
50 50 51 51 52 52 53 54 54 55 55 55 56 56 57
We have 15 values in total and the median is located at
location
The
value is 54 which is the best measure of center for the data set.
