What is the quotient of 3 1/8 and 1 2/7 in simplest form.
Reika [66]
A quotient refers to division so 

1/8 = 0.125
2/7 = 0.285 

3.125/1.285 = 2.432

Sam intends to roll a six sided cube 100 times. What is the probability model he can use to predict whether or not each roll wil
bekas [8.4K]

The outcomes of rolling fair six sided die is \{1,2,3,4,5,6\}. The prime numbers in the above outcomes are \{2,3,5\}. The probability of not rolling a prime number is p=\frac{3}{6}= 0.5.

Each trial is independent.

In the given experiment of 100 trials, the binomial probability model can be used to predict the number of occurrence of non-prime numbers (X). The probability mass function is

P(X=x)=C(100,x)p^x(1-p)^{100-x},x=0,1,2,3,...,100. Since p=0.5,1-p=0.5

P(X=x)=C(100,x)0.5^x(0.5)^{100-x},x=0,1,2,3,...,100 \\ P(X=x)=C(100,x)(0.5)^{100},x=0,1,2,3,...,100

Can anyone help me on this problem? Please it doesn’t make sense to me...
Sav [38]

Answer:

6

Step-by-step explanation:

Cost per item is found by dividing the cost by the number of items. If the woman bought n items for $120, the cost of each item is $120/n. If the woman bought 24 more items, n+24, at the same price, then the cost per item is $120/(n+24). The problem statement tells us this last cost is $16 less than the first cost:

120/(n+24) = (120/n) -16

Multiplying by n(n+24) gives ...

120n = 120(n+24) -16(n)(n+24)

0 = 120·24 -16n^2 -16·24n . . . . . . subtract 120n and collect terms

n^2 +24n -180 = 0 . . . . . . . . . . . . . divide by -16 to make the numbers smaller

(n +30)(n -6) = 0 . . . . . . . . . . . . . . factor the quadratic

The solutions to this are the values of n that make the factors zero: n = -30, n = 6. The negative value of n has no meaning in this context, so n=6 is the solution to the equation.

The woman bought 6 items.

_____

Check

When the woman bought 6 items for $120, she paid $120/6 = $20 for each of them. If she bought 6+24 = 30 items for the same money, she would pay $120/30 = $4 for each item. That amount, $4, is $16 less than the $20 she paid for each item.
