Answer:
See below
Step-by-step explanation:
Out of 25 games, they won 14
Fraction won = won / total = 14 / 25
Percent won = won /total * 100 % = 14/25 * 100 = .56 * 100 % = 56 %
To find the number of games lost
25-14 = 11
Fraction won = won / total = 11 / 25
Percent won = won /total * 100 % = 11/25 * 100 = .44 * 100 % = 44 %
To check your work, the percent total should be 100
56+44 = 100
To find the inverse, interchange the variables and solve for y.
f^−1(x)=−25+5x/2
Answer:
a. no b. 40.05
Step-by-step explanation:
a. to figure out the number of goals per game you have to divide the total amount of goals by the number of games:
last season: 41 ÷ 15 = 2.73
this season: 24 ÷ 9 = 2.67
as you can see the answer to the last season equation is higher than the this season meaning the player scored more goals last season.
b. we already know that the amount of games the player won each game (all of them supposedly being exactly even) is 2.67. so what we have to do is multiply it by 15 the supposed number of games the player is playing this season to get the total number of goals they will get for the entire season:
2.67 x 15 = 40.05 = the prediction of the total goals of the player
Step-by-step explanation:
(x-2)^3 = x^3-6x^2+12x-8
-(x^3-6x^2+12x-8)=
-x^3+6x^2-12x+8
-x^3+6x^2-12x+8 -5=
y=-x^3+6x^2-12x+3
