You have to turn 65 into a decimal. That would be .65
They do 39/.65
You should get 60 as your final answer.
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>

i dont know how to show my work sorry :) hope it helps
Answer:
A.) -5
Step-by-step explanation:
<em>Slope Formula ---> </em>
<em>m = slope</em>
<em>Eliminate negatives:</em>
<em>Solve:</em>
<em>Simplify:</em>
PEMDAS means we do exponents before we multiply.
10 ^ 7 = 10,000,000
(10 * 10 * 10 * 10 * 10 * 10 * 10)
5.8 * 10,000,000
= 58,000,000
