Write an expression to represent the length of a string in yards in terms of the string's length, x, in inches
Sergio039 [100]

Answer:

y = \frac{x}{36}

Step-by-step explanation:

Given

Length of string = x inches

Required

Determine the length in yards

Represent the equivalent length with y

Such that

y = x\ inches

Divide x by 36 to get equivalent in yards

y = \frac{1}{36} * x

y = \frac{x}{36}

Hence, the equivalent in yards is \frac{x}{36}

A nationwide census is conducted and it is found that the mean number of hours of television watched per year by Americans is 35
Ber [7]

Answer:

Probability that a group of 4 Americans watch more than 400 hours of television per year is 0.3264.

Step-by-step explanation:

We are given that a nationwide census is conducted and it is found that the mean number of hours of television watched per year by Americans is 350 with a standard deviation of 220.

A group of 4 Americans is selected.

Let \bar X = <u><em>sample mean number of hours of television watched per year</em></u>

The z score probability distribution for sample mean  is given by;

                             Z  =  \frac{\bar X-\mu}{\frac{\sigma}{\sqrt{n} } }  ~ N(0,1)

where, \mu = population mean = 350

            \sigma = standard deviation = 220

            n = sample of Americans = 4

Now, the probability that a group of 4 Americans watch more than 400 hours of television per year is given by = P(\bar X > 400 hours)

     

     P(\bar X > 400) = P( \frac{\bar X-\mu}{\frac{\sigma}{\sqrt{n} } } > \frac{400-350}{\frac{220}{\sqrt{4} } } ) = P(Z > 0.45) = 1 - P(Z \leq 0.45)

                                                        = 1 - 0.6736 = <u>0.3264</u>

The above probability is calculated by looking at the value of x = 0.45 in the z table which has an area of 0.6736.

Hence, the probability that a group of 4 Americans watch more than 400 hours of television per year is 0.3264.
