Answer:
The ratio of Trucks to Cars is
The ratio of Hot Dogs to Hamburgers is
Step-by-step explanation:
There are 42 cars and 9 trucks, and since they asked to write the ratio of trucks to cars, we write it as they asked. Therefore the ratio would be
There are 24 hotdogs and 40 hamburgers, since they asked us to write the ratio of hotdogs to hamburgers we are going to write it as it was said. Therefore the ratio is
Answer:
f is increasing on interval (-infty, 13/4)
Inequality notation: x<13/4
In words: f is increasing on the interval of x that is less than 13/4.
Step-by-step explanation:
f is increasing on interval of x if f' of such interval is positive.
f=-2x^2+13x-8
Differentiate both sides
(f)'=(-2x^2+13x-8)'
Sum and difference rule:
f'=(-2x^2)'+(13x)'-(8)'
Constant multiple rule:
f'=-2(x^2)'+13(x)'-(8)'
Power rule (recall x=x^1):
f'=-2(2x^1)+13(1x^0)-(8)'
Constant rule:
f'=-2(2x^1)+13(1x^0)-(0)
Recall again x^1=x:
f'=-2(2x)+13(1x^0)-(0)
Recall x^0=1:
f'=-2(2x)+13(1×1)-(0)
Associative property of multiplication:
f'=-(2×2)x+13(1×1)-(0)
Performed grouped multiplication:
f'=-(4)x+13(1)-(0)
f'=-4x+13-(0)
Additive identity:
f'=-4x+13
f' is positive when -4x+13>0.
Subtract 13 on both sides:
-4x>-13
Divide both sides by -4:
x<-13/-4
x<13/4
f is increasing on interval (-infty, 13/4)

The probability of picking a red marble three times in a row with replacement is:
number of red marbles divided by total number of marbles cubed...
(6/10)^3=27/125
The above is the theoretical probability...
From the chart we see that three reds in a row happened twice in twenty-five trials so the experimental probability is:
2/25
The experimental probability about 0.14 less than theoretically expected...
C)
