Answer:

  • x = 10
  • y = 7.5

Step-by-step explanation:

The ratio of the larger to the smaller corresponding sides is ...

  12.5/5 = 2.5

That means ...

  x = 2.5 × 4 = 10

  y = 2.5 × 3 = 7.5

Explain why P(A|D) and P(D|A) from the table below are not equal.
trasher [3.6K]

Answer:

The Probability that Event A and  Event D occur is equal to the probability Event A occurs times the probability that Event D occurs, given that A has occurred.


P(A\cap D)=P(A)\cdot P(D/A)

We can find the values of P(A/D) and P(D/A) using the above form formula.

P(D/A)=\frac{P(A\cap D)}{P(A)} ;

P(A/D)=\frac{P(D\cap A)}{P(D)}

From the given table, we have the values of P(A), P(D), P(D\cap A) and P(A\cap D).

Since, Probability=\frac{The number of wanted outcomes }{the number of possible outcomes}

∴P(A)=\frac{8}{17}, P(D)=\frac{10}{17}, P(A\cap D)=\frac{2}{17} and P(D\cap A)=\frac{2}{17}

Now, putting these values in above formula we get,

P(D/A)=\frac{\frac{2}{17}} {\frac{8}{17}}

P(D/A)=\frac{2} {8}=\frac{1}{4}

P(D/A)= \frac{1}{4}.

P(A/D)=\frac{\frac{2}{17}} {\frac{10}{17}}=\frac{2}{10}

P(A/D)=\frac{1}{5}

As, you can see above that the values of P(A|D) and P(D|A) are not equal.

Rewrite each of the following radicals as a rational number or in simplest radical form. a. √49b. ∛40c. √242
Usimov [2.4K]

Answer

given radicals

convert them into simplest radical form

a) √49

  √49 = \sqrt{7\times 7}

           = 7

b)  ∛40

      ∛40 = \sqrt[3]{2\times 2\times 2\times 5}

              = 2 ∛5

c) √242

   √49 = \sqrt{2\times 11\times 11}

           = 11 √2

hence the number are converted into simplest radicals or rational form.
