Answer:

y=7x

Step-by-step explanation:

Notice that if you divide each n-value by its correspoding m-value, you always have 7 as a result, that means it's the constant ratio of change,

21/3 = 7

35/5 = 7

56/8 = 7

Now, this is a linear relatioship by definition, where its constant ratio is 7, but geometrically, that ratio is the slope of a linear equation.

So, we need to use the slope 7, one pair from the table and the point-slope formula

y-y_{1} =m(x-x_{1} )\\y-21=7(x-3)\\y=7x-21+21\\y=7x

<h3>Therefore, an equation that models the given table is</h3>

y=7x

Consider an unreliable communication channel that can successfully send a message with probability 1/2, or otherwise, the messag
Anon25 [30]

Answer:

6 times we need to transmit the message over this unreliable channel so that with probability 63/64.

Step-by-step explanation:

Consider the provided information.

Let x is the number of times massage received.

It is given that the probability of successfully is 1/2.

Thus p = 1/2 and q = 1/2

We want the number of times do we need to transmit the message over this unreliable channel so that with probability 63/64 the message is received at least once.

According to the binomial distribution:

P(X=x)=\frac{n!}{r!(n-r)!}p^rq^{n-r}

We want message is received at least once. This can be written as:

P(X\geq 1)=1-P(x=0)

The probability of at least once is given as 63/64 we need to find the number of times we need to send the massage.

\frac{63}{64}=1-\frac{n!}{0!(n-0)!}\frac{1}{2}^0\frac{1}{2}^{n-0}

\frac{63}{64}=1-\frac{n!}{n!}\frac{1}{2}^{n}

\frac{63}{64}=1-\frac{1}{2}^{n}

\frac{1}{2}^{n}=1-\frac{63}{64}

\frac{1}{2}^{n}=\frac{1}{64}

By comparing the value number we find that the value of n should be 6.

Hence, 6 times we need to transmit the message over this unreliable channel so that with probability 63/64.
