Answer:
D: 19 should have been subtracted from, not added to, both sides of the equation.
Step-by-step explanation:
Because if we subtract 19 from both sides, we directly get the value of x.
Equation:-
x + 19 = 34
Subtracting 19 from both sides,
=> x + 19 - 19 = 34 - 19
=> x = 15
Answer:
D,F
Step-by-step explanation:
D . x cubed is 5 times 5 which is 25 times 5 which is 125
F x squared is 5 times 5 which is 25
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>
You would each get 1/10 of a pound of trail mix
