Major league baseball game durations are normally distributed with a mean of 160 minutes and a standard deviation of 50 minutes.
Akimi4 [234]

Answer:

0.19

Step-by-step explanation:

μ = 160 and σ = 50.  Find the z scores for 180 and 210.

z = (x - μ) / σ

z = (180 - 160) / 50 = 0.40

z = (210 - 160) / 50 = 1.00

So we want P(0.40<z<1.00).  This can be found as:

P(0.40<z<1.00) = P(z<1.00) - P(z<0.40)

Now use a calculator or table to find each probability:

P(0.40<z<1.00) = 0.8413 - 0.6554

P(0.40<z<1.00) = 0.1859

Rounded to the nearest hundredth, P ≈ 0.19.

Solve the following equation:<br><br> 3 x seven tenths
djverab [1.8K]
<h3>hello!</h3>

=================================================

Here, we have to multiply fractions.

How to Multiply Fractions?

Here are the steps:-

<u />

  • Turn any whole numbers into fractions (example:- 3 = 3/1)
  • Multiply the numerator of the first fraction times the numerator of the 2nd fraction; same with the denominator.
  • Simplify if necessary.

So let's do it.

Step 1:-

\longmapsto\sf{3=\displaystyle\frac{3}{1}

Step 2:-

\longmapsto\sf{\displaystyle\frac{3}{1} *\frac{7}{10}}

\longmapsto\sf{\displaystyle\frac{21}{10} }

We can't simplify this fraction, but there's something else we can do:-

  • Convert this improper fraction into a mixed number

Here's the answer:-

\boxed{\sf{2\displaystyle\frac{1}{10} }}

=====================================================

<h3>note:-</h3>

Hope everything is clear; if you need any explanation/clarification, kindly let me know, and I will comment and/or edit my answer :)
