There are 91 in total. Since there are 21 red cars, it would give you 21/91. Around a 23.07% chance.
Answer: 107
Step-by-step explanation:
When you match the pattern of (x+y)⁴ to (a+b)ⁿ, you see that a=x, n=4. Then the first term aⁿ can be found by substituting these values for "a" and "n":
... x⁴
Just add the numerators and the answer becomes (4/x–4)
Answer:
Therefore
, A=184
Step-by-step explanation:
Given function is

where T(t) is the temperature in °C and t is time in minute and A and k are constants.
She noticed that after 18 minutes the temperature of the pie is 138°C
Putting T(t) =138°C and t= 18 minutes


.....(1)
Again after 36 minutes it is 184°C
Putting T(t) =184°C and t= 36 minutes


.......(2)
Dividing (2) by (1)


Taking ln both sides




Putting the value k in equation (1)





⇒A= 184.
Therefore
, A=184
