Answer:

≈ 4.92957 or 350/71 ounces

Step-by-step explanation:

x/140 = 1/28.4 (x is the ounces in 140 grams, as there is 1 ounce in 28.4 grams)

Multiplying both sides by 140 gives us x = 140/28.4

Dividing 140/28.4 gives us 4.92957... or 350/71.

None of the offered choices is correct.

The radical cannot be simplified. If rewritten, it must be written as something like
x \sqrt[3]{ \frac{6}{x}}
or
\frac{6x}{ \sqrt[3]{36x}}

A bank in the Bay area is considering a training program for its staff. The probability that a new training program will increas
WITCHER [35]

Answer:

P(B' \cup A') = P((A \cap B)') = 1-P(A \cap B)= 1-0.32=0.68

See explanation below.

Step-by-step explanation:

For this case we define first some notation:

A= A new training program will increase customer satisfaction ratings

B= The training program can be kept within the original budget allocation

And for these two events we have defined the following probabilities

P(A) = 0.8, P(B) = 0.2

We are assuming that the two events are independent so then we have the following propert:

P(A \cap B ) = P(A) * P(B)

And we want to find the probability that the cost of the training program is not kept within budget or the training program will not increase the customer ratings so then if we use symbols we want to find:

P(B' \cup A')

And using the De Morgan laws we know that:

(A \cap B)' = A' \cup B'

So then we can write the probability like this:

P(B' \cup A') = P((A \cap B)')

And using the complement rule we can do this:

P(B' \cup A') = P((A \cap B)')= 1-P(A \cap B)

Since A and B are independent we have:

P(A \cap B )=P(A)*P(B) =(0.8*0.4) =0.32

And then our final answer would be:

P(B' \cup A') = P((A \cap B)') = 1-P(A \cap B)= 1-0.32=0.68
