I'll get you started. Let x and y be the two numbers. we have: x + y = 74 (sum is 74) x = 4y - 6 (the number x is six less than 4 times y) Now that you have the equations use an algebraic techniques to eliminate one variable thereby solving for the other. If you need more help add a comment to your question.
Given :
An irrational number ,
.
To Find :
Two consecutive whole numbers that square root of 31 lies between.
Solution :
We know , square root of 36 is 6.
Also, square root of 25 is 5.
Now, we can see that
lies between 5 and 6. Also, both 5 and 6 are consecutive.
Therefore, between 5 and 6 is the solution.
Hence, this is the required solution.
Answer:
0.2700
Step-by-step explanation:
-Notice that this is a binomial distribution with p=0.52, n=4 and x=3.
-The formula for the binomial probabilities is given as:

The probability than in 4, exactly 3 order their food on the go is:

Hence, the probability that exactly 3 order their food on the go is 0.2700
