Frank has two same size rectangles divided into the same number of equal parts. One rectangle has 3/4 of the parts shaded and th

e other has 1/3 of the parts shaded.
Part A
Into how many parts could each rectangle be divided? show your work by drawing the parts of each rectangle.

Part B
Is there more than one possible answer to Part A? If so, did you find the least number of parts into which both rectangles could be divided? Explain your reasoning.

<span>Part A has many different answers, so as long as it can be divided by 3 or 4, that's the most parts that both rectangle can be divided into. Part B yes, there are many different possible answers in part A, and in order to find out the least number of parts that the rectangle could be divided is by determining the least common denominator of 1/3 and 3/4, and that would be 12, so it can be divided into at least 12 parts.</span>

A recipe requires one quarter cup of milk as a base and then, in addition, 1 cup of milk for every 4 cups of flour. Choose a lin

It should be A because for every one cup of milk, x, there is four times as much flour. This means to get flour, you multiply x by 4.

A company manufactures tires at a cost of $40 each. The following are probabilities of defective tires in a given production run
asambeis [7]

Answer:

The expected cost of the company for a 3000 tires batch is $120255

Step-by-step explanation:

Recall that given a probability of defective tires p, we can model the number of defective tires as a binomial random variable. For 3000 tires, if we have a probability p of having a defective tire, the expected number of defective tires  is 3000p.

Let X be the number of defective tires. We can use the total expectation theorem, as follows: if there are A_1,\dots, A_n events that partition the whole sample space, and we have a random variable X over the sample space, then

E(X) = p(A_1)E(X|A_1) + \dots + p(A_n)E(X|A_n).

So, in this case, we have the following

E(X) = P(p=0\%)E(X|p=0\%)+P(p=1\%)E(X|p=1\%)+P(p=2\%)E(X|p=2\%)+P(p=3\%)E(X|p=3\%) = 0.1\cdot 3000\cdot 0 + 0.3\cdot 3000\cdot 0.01+ 0.4\cdot 3000\cdot 0.02+ 0.2\cdot 3000\cdot 0.03 = 51.

Let Y be the number non defective tires. then X+Y = 3000. So Y = 3000-X. Then E(Y) = 3000-E(X). Then, E(Y) = 2949.

Finally, note that the cost of the batch would be 40Y+45X. Then

E(40Y+45X) = 40E(Y)+45E(X) = 40\cdot 2949+45\cdot 51=120255
