Answer:

D=14.96 inch

Step-by-step explanation:

Given :

Circumference of a circle is 47

C=2πr

47=2πr

47=6.28r

r=\frac{47}{6.28} \\r=7.484 in.\\D=2r\\D=2(7.48)\\D=14.96 in.

Therefore, diameter of the circle is 14.96 inch

{ \bf{ \underbrace{Given :}}}

Circumference of the circle = 47 inch.

{ \bf{ \underbrace{To\:find:}}}

The diameter of the circle.

{ \bf{ \underbrace{Solution :}}}

\sf\orange{The\:diameter\:of\:the\:circle\:is\:15\:inch.}

\large\mathfrak{{\pmb{\underline{\blue{Step-by-step\:explanation}}{\blue{:}}}}}

We know that,

\sf\purple{Circumference\:of\:a\:circle \:=\:2πr }

\longrightarrow{\blue{}} 47 in = 2 π r

\longrightarrow{\blue{}} r = \frac{47 \times 7}{2 \times 22} in

\longrightarrow{\blue{}} r = \frac{329}{44} in

\longrightarrow{\blue{}} r = 7.477 in

Now,

\sf\pink{Diameter\: of \:the \:circle\: =\: 2 \:r }

= 2 x 7.477 in

= 14.954 in

= 15 in ( round to nearest whole number )

Therefore, the diameter of the circle is 15 inch.

A true-false question is to be posed to a husband and wife team. Both the husband and the wife will give the correct answer with
marysya [2.9K]

Answer:

Choose either strategy both are equally successful

Step-by-step explanation:

Given:-

- The probability of success for both husband (H) and wife (W) are:

                              P ( W ) = 0.8 , P ( H ) = 0.8

Find:-

- Which of the following is a better strategy for the couple?

Solution:-

Strategy 1

- First note that P ( W ) & P ( H ) are independent from one another, i.e the probability of giving correct answer of husband does not influences that of wife's.

- This strategy poses an event such that either wife knows the answer and answer it correctly or the husband knows and answers in correctly.

- We will assume that probability of either the husband or wife knowing the answer is 0.5 and the two events of knowing and answering correctly are independent. So,

                           P ( Wk ) = P (Hk) = 0.5

- The event P(S1) is:

                           P(S1) = P ( Hk & H ) + P ( Wk & W )

                           P(S1) = 0.5*0.8 + 0.5*0.8

                           P(S1) = 0.8

- Hence, the probability of success for strategy 1 is = 0.8

Strategy 2

- Both agree , then the common answer is selected otherwise, one of their answers is chosen at random.

- The success of strategy 2, will occur when both agree and are correct, wife is correct and answers while husband is not or husband is correct and he answers.

- The event P(S2) is:

                   P(S2) = P ( H & W ) + P ( H / W' & Hk ) + P ( H' / W & Wk )

                   P(S2) = P ( H & W ) + P ( H / W') P ( Hk ) + P ( H' / W) P (Wk)

                   P(S2) = P ( H & W ) + P ( H / W')*0.5  + P ( H' / W)*0.5

                   P(S2) = 0.5* [ P ( H & W ) + P ( H / W') ]  + 0.5* [ P ( H' / W) + P ( H & W )]

                   P(S2) = 0.5*P(H) + 0.5*P(W)

                   P(S2) = 0.5*0.8 + 0.5*0.8

                   P(S2) = 0.8

- Hence, the probability of success for strategy 2 is = 0.8

Both strategy give us the same probability of success.
