Z = (X-Mean)/SD
<span>z1 = (165 - 150)/15 = +1 </span>
<span>z2 = (135 - 150)/15 = - 1 </span>
<span>According to the Empirical Rule 68-95-99.7 </span>
<span>Mean +/- 1SD covers 68% of the values </span>
<span>100% - 68% = 32% </span>
<span>The remaining 32% is equally distributed below z = - 1 and z = +1 </span>
<span>32%/2 = 16%
</span>
<span>Therefore,
</span>
<span>a) Number of men weighing more than 165 pounds = 16% of 1000 = 160 </span>
<span>b) Number of men weighing less than 135 pounds = 16% of 1000 = 160</span>

Answer:
64.7%
Step-by-step explanation:
To solve this problem we use compounded interest formula.
a = amount
p = principle
r = interest rate
n = number of times compounded in a period
t = time period
a = 1647.01
1647.01-1000 = 647.01
647.01/1000 = 0.64701
0.64701*100% = 64.7%
80-45+5+2=42
Your answer is 42
Answer:
i think the answer is x=1
