What is the value of 13.997x4 to 2 decimal places ?
VARVARA [1.3K]

Answer:

Hence the answer to 2 decimal places becomes 55.99

Step-by-step explanation:

SOLUTION

We want to solve:

13.997×4 to 2 decimal places

Now:

13.997×4=55.988

Now, 55.988 to decimal places, after the decimal point, we count the first two numbers, which are 9 and then 8. Then check the number after the 8, is it up to 5? Yes, it is, because it is 8. Now change the 8 to 1 and add it to that second number after the decimal point, this gives nine.

Hence the answer to 2 decimal places becomes 55.99

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

Salsk061 [2.6K]

Answer:

113

Step-by-step explanation:

note: to find the circumference of a circle using the radius, you use this equation -- 2\pir. since the radius is 18, you make the equation 2\pi18. that gets you 36\pi, which, if put into the calculator, is about 113.
