Carlton ran 7 3/4 miles in 52 7/10 minutes. what is his average pace per minute?
SCORPION-xisa [38]

Answer:

  5/34 mi/min

Step-by-step explanation:

To find miles per minute, divide miles by minutes:

  (7 3/4 mi)/(52 7/10 min) = (31/4 mi)/(527/10 min)

  = (31/4)(10/527) mi/min = 310/2108 mi/min = 5/34 mi/min

Carlton's average pace was 5/34 miles per minute.

___

Since the given numbers are mixed numbers, we assume this is supposed to be a problem in fractions. Hence we have given the answer as a fraction. Its decimal value is about 0.14706. It is a repeating decimal with a 16-digit repeat.

You may have to do a little work to reduce the fraction 310/2108 to 5/34. You have to factor out a factor of 62. The numerator is 310=2·5·31, so that gives you a short list of factors to try with the denominator.

Major league baseball salaries averaged $3.26 million with a standard deviation of $1.2 million in a the past year. Suppose a sa
strojnjashka [21]

Answer:

0.015 is the approximate probability that the mean salary of the 100 players was less than $3.0 million

Step-by-step explanation:

We are given the following information in the question:

Mean, μ =$3.26 million

Standard Deviation, σ = $1.2 million 100

We assume that the distribution of salaries is a bell shaped distribution that is a normal distribution.

Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

Standard error due to sampling =

\displaystyle\frac{\sigma}{\sqrt{n}} = \frac{1.2}{\sqrt{100}} = 0.12

P(mean salary of the 100 players was less than $3.0 million)

P(x < 3) = P(z < \displaystyle\frac{3-3.26}{0.12}) = P(z < -2.167)

Calculating the value from the standard normal table we have,

P(Z < -2.167) = 0.015 \\P( x < 3) = 1.5\%

0.015 is the approximate probability that the mean salary of the 100 players was less than $3.0 million
