Answer:
<em>The compound inequality that shows the voltage amount the necessary range is
</em>
Step-by-step explanation:
Loni needs between 3.5 and 7.2 volts of energy, not inclusive, to make an experiment work correctly.
That means, <u>the voltage amount should be either greater than 3.5 volts or less than 7.2 volts</u>.
Suppose, the amount of voltage is
volts to make the experiment work correctly.
Now, Voltage amount is greater than 3.5 volts means:
or 
and voltage amount is less than 7.2 volts means: 
Thus, the compound inequality by combining the above two inequalities will be: 
Answer:
Any number both positive or negative.
y = {all numbers}
Step-by-step explanation:
Answer:
n=7 or n=-7
Step-by-step explanation:
Let's apply the Law of Cosines here. We want the measure of the angle opposite the side with length 16.
Call that angle C.
Then 16^2 = 36^2 + 28^2 - 2(36)(28)cos C.
Solving for C: cos C = 16^2 - 36^2 - 28^2
------------------------- = 0.904, and C = 0.44 rad
-2(28)(36) or C = 25.21 degrees
So each of the 2 equal angles shown has the measure 25.21 degrees.
Unfortunately, I don't know the direction we should go from this point on.
7 yellow, 5 green, 3 blue...total of 15
P(yellow party hat) = 7/15
do not replace
P(yellow hat) = 6/14
P(both) = 7/15 * 6/14 = 42/210 which reduces to 1/5 or 0.2 or 20%
