Answer:
A. 2
Step-by-step explanation:
1/10 ranked vanilla before chocolate, and 1/3 ranked vanilla before strawberry.
So for the people who ranked vanilla fist, they would have had to ranked it before chocolate and also before strawberry.
So whe have a case of cumulative probability, we have to multiply the probability that it has to be chosen before chocolate, by the probability of being choosen before strawberry so we make sure vanilla was the first:
so two people out of the 60 choosed vanilla as their fist option
Answer:
m ABC is 42
Step-by-step explanation:
x = 3
3 x 3 = 9 + 33 = 42
Answer:
Quadratic (I took the test)
Step-by-step explanation:
y=t+2 equals y-2=t
put t in for x=t^1/2. this is x=(y-2)^1/2, which equals x^2=y-2.
add 2 to both sides, which is y=x^2+2 . This is an example of a quadratic equation (you kinda just need to know the format of different types of equations for the last part. It isn't cubic because it has a number added to it, isn't linear because the x is squared, and tbh I have no clue what quartic is.)
LCM of 75,45 and 60 is 900.
The divisor of 75,45 and 60 must be a multiple of their LCM.
75×900=67500 )⤵
45×900=40500 )↪ not a 3 digits no.
60×900=54000 )⤴
Since they are not 3 digits no..the greatest 3 digits no exactly divisible by 75,45,60 must be the LCM itself i.e. 900 >>Ans
Now,the next question is very simple.As the 900
greatest divisor of all given no., add 4 to get remainder 4 when divided by 75,60 and 45.
So, ans=904
