Answer:
0.9544
Step-by-step explanation:
P(-2 < Z < 2) means that Z has mean 0 and standard deviation 2.
P(−2 < Z < 2) = F(2) - F(-2)
Using the Z - table,
F(2) = 0.9772
and F(-2) = 0.0228
Thus,
P(−2 < Z < 2) = 0.9772 - 0.0228 = 0.9544
This means that data within two standard deviation is 95%.
Answer:
See the net of the prism in the attachment
<u>It has 6 faces with sizes:</u>
- Two off 4 in x 25 in

Let h = weight of the hardcover book.
Let p = weight of the paperback book.
<span>"The hardcover version of a book weighs twice as much as its paperback version."
h = 2p
"</span><span>The hardcover book and the paperback together weigh 5.3 pounds.</span><span>"
h + p = 5.3
The equations are:
h = 2p
h + p = 5.3
