Answer:
Range : {11,27,43,59}
Step-by-step explanation:
Given:
f(x) = 4x - 1
Domain : {3,7,11,15}
f(3) = 4(3) -1 = 11
f(7) = 4(7) -1 = 27
f(11) = 4(11) -1 = 43
f(15) = 4(15) -1 = 59
hence Range : {11,27,43,59}
Answer:
Step-by-step explanation:
z score= x - mean/standard deviation
1.20= x -100/15
18= x -100
118=x
z score= x - mean/standard deviation
0.5=x-73/4
2=x-73
75= x
H=Hours he an skate; T=total cost
T=$7.00+($1.50/hr)H
T-$7.00=($1.50/hr)H
(T-$7.00)/($1.50/hr)=H
For T=$19:
($19.00-$7.00)/($1.50/hr)=H
$12.00/($1.50/hr)=H
8hrs=H
ANSWER: Jon can skate 8 hours for $19.00.
Hope this helps!
Number one is 2,1206
