Suppose the lengths of the pregnancies of a certain animal are approximately normally distributed with mean mu equals 280 days a

a_sh-v [17]

First, find the z-score:

z = (value - mean) / sdev
= (275 - 280) / 15
= - 0.33

In order to use a standard normal table, we need a positive z-score:
P(z < -0.33) = 1 - P(z < 0.33)

Looking at the table, we find P(z < 0.33) = 0.6293

Therefore:
P(z < -0.33) = 1 - 0.6293 = 0.3707

Hence, you have a probability of about 37% <span>that a randomly selected pregnancy lasts less than 275 days.</span>

A man walked steadily from 11 am to 2.30 pm at 5 kilometres per hour how far did he walk!

matrenka [14]

Answer:

Distance traveled 17.5 kilometers

Step-by-step explanation:

We can use the following equation to find the distance traveled,

Distance traveled = Speed * Time

First we need to find the total time he walked = 2.30 p.m. - 11.a.m.

= $3.5$ hours

Now we can substitute the values to the equation,

Distance traveled = $5$ kilometers per hour * $3.5$ hours

= $5*3.5$ kilometers

= 17.5 kilometers
