Answer:

Step-by-step explanation:
Since we're finding the product, we have to multiply:
× 
You can simplify in this stage by using the "butterfly method", and dividing
by
, and
by
, you'd then have:
× 
Multiply the numerators and the denominators to get:

~
If you prefer the longer way, again, multiply:
× 
Multiply the numerators and the denominators:

Simplify the fraction by dividing both the numerator and denominator by
:

0.35+0.2+.25
=0.55+0.2
=0.57
=57/100 miles
So, we have
<span>Z=<span><span>x−μ / </span>σ
</span></span><span>Mean would be = 56
30 - 56 = |-26|
4
3 - 56 = |-13|
and
Standard deviation= 13
</span><span>2 - 1 will give us the approximate area
95/2 - 68/2 = N
95
-68 = 27
27 /2 = 13.5
</span>Hence, the answer would be
<span>800,000 * .135
</span>= <span> 108000</span>
Let's put it this way: If you plot a few non-x-intercept points and then draw a curvy line through them,you will not know if you got the x-intercepts even close to being correct. <span>The only way you can be sure of your x-intercepts is to set the quadratic equal to zero and solve. So its a matter of guessing from the pictures. Basicaly said, the calculator won't give you the exact result.</span>
Answer:
a) 42°F < x < 176°F
b) The inequality graph is attached.
c) No, This is because at 20° F benzene would not be in liquid form but in solid form.
Step-by-step explanation:
According to the Question,
a) For the benzene to remain in liquid form, the temperature of benzene must be less than the boiling point and greater than the boiling point. Let x be the temperature of benzene, For benzene to remain as liquid, its temperature must be between:
42°F < x < 176°F
b) The inequality graph is attached. The graph shows that the temperature of benzene must be between 42°F and 176°F so that it would be a liquid. The Closed circles represent that it is greater than 2.
c) No, This is because at 20° F benzene would not be in liquid form but in solid form. Because the temperature cannot go below 42 before it freezes, she would not have been able to conduct her research .
