Find the value of x in similar polygons below
muminat

Answer:

Choice A

Step-by-step explanation:

When you have two shapes that are similar their sides are always proportional. So all we have to do is set up a proportion.

\frac{18}{4.5}=\frac{x}{1.5}

Now we cross multiply and solve

27=4.5x\\x=6

And that's it x equals 6 feet.

Given a mean of 150 and a standard deviation of 25 Define the interval about the mean that contains 95% of the data.
ohaa [14]
By normal curve symmetry 

<span>from normal table </span>
<span>we have z = 1.15 , z = -1.15 </span>

<span>z = (x - mean) / sigma </span>
<span>1.15 = (x - 150) / 25 </span>
<span>x = 178.75 </span>


<span>z = (x - mean) / sigma </span>
<span>-1.15 = (x - 150) / 25 </span>
<span>x = 121.25 </span>

<span>interval is (121.25 , 178.75) </span>

<span>Pr((121.25-150)/25 < x < (178.75-150)/25) </span>
<span>is about 75%</span>
