The 8 is in the tenth place. There is a 7 in the hundredths place. Since 7 is greater than or equal to 5, we round the 8 up. So it becomes a 9.
1129.9
Answer: 1129.9
The probability of the 2 events are multiplied to get the result 10/91
so we have the relation 5/14 * x = 10/91
where x is the probability of drawing the second black
so x = 10/91 * 14/5 = 4/13 answer
Answer:
57.9
Step-by-step explanation:
Answer:
you have done 1/4 ... ....
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>
