Answer:
x=39, y=180
Step-by-step explanation:
f(x)=0.4x²-31.2x+788.4
For x=39 the graph reaches its lowest point.
The minimum value of y is:
x=39→y=f(39)=0.4(39)²-31.2(39)+788.4
y=f(39)=0.4(1,521)-1,216.8+788.4
y=f(39)=608.4-1,216.8+788.4
y=f(39)=180
Answer:
Step-by-step explanation:
Team A : the mean height (average) is :
(75 + 64 + 78 + 65 + 68) / 5 = 350/5 = 70 inches
the range is highest number minus lowest number ...78 - 64 = 14
Team B : the mean height (average) is :
(76 + 68 + 70 + 74 + 67) / 5 = 355/5 = 71 inches
the range is : 76 - 67 = 9
===========================================================
A). nope....it mentions nothing of the weight
B) nope....mean height of team A is not greater
C) nope...because that 75 inch player on team A
D) THIS ONE....the range for team A is greater then the range for team B
I hope this helps you
x=4
f (4)=4+3
f (4)=7
x= -2
g (-2)=13. (-2)-5
g (-2)= -26-5
g (-2)= -31
f (4)+g (-2)= 7 -31= -24
