The skate Sports Store offers 4-wheel and 5-wheel inline skates. On display in the store are the left skates for 17 different st
beks73 [17]

There are 6 skates in store with 5 wheels.

<h3>What is Equation?</h3>

Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign.

Here, Let the number of 4 wheel skates in display be x

         and the number of 5 wheel skates in display be y

       Total number of skates = 17

       Total number of wheel = 74

Now, according to question

        x + y = 17     ................(i)

        4x + 5y = 74 ..................(ii)

From equation (i), we get

          x = 17 - y   ................(iii)

put the value of y in equation (ii), we get

      4(17 - y) + 5y = 74

       68 - 4y + 5y = 74

          y + 68 = 74

          y = 6

Put the value of y in equation (iii), we get

          x = 17 - 6

          x = 11

Thus, there are 6 skates in store with 5 wheels.

Find the probability that a randomly generated bit string of length 10 does not contain a 0 if bits are independent and if a 0 b
jeka94

Answer:

Step-by-step explanation:

From the given information; Let's assume that  R should represent the set of all possible outcomes generated from  a bit string of length 10 .

So; as each place is fitted with either 0 or 1

\mathbf{|R|= 2^{10}}

Similarly; the event E signifies the randomly generated bit string of length 10 does not contain a 0

Now;

if  a 0 bit and a 1 bit are equally likely

The probability that a randomly generated bit string of length 10 does not contain a 0 if bits are independent and if a 0 bit and a 1 bit are equally likely is;

\mathbf{P(E) = \dfrac{|E|}{|R|}}

so ; if bits string should not contain a 0 and all other places should be occupied by 1; Then:

\mathbf{{|E|}=1 }   ; \mathbf{|R|= 2^{10}}

\mathbf{P(E) = \dfrac{1}{2^{10}}}
