Answer:
y = -1
Step-by-step explanation:
1y + 14 = -4y + 9
Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Add 4y and subtract 14 from both sides:
1y (+4y) + 14 (-14) = -4y (+4y) + 9 (-14)
1y + 4y = 9 - 14
5y = -5
Divide 5 from both sides:
(5y)/5 = (-5)/5
y = -5/5 = -1
-1 is your answer for y.

Answer:
<h2>The segment FE is a tangent of the sphere.</h2>
Step-by-step explanation:
Obseve the sphere in the image attached.
Notice that point A is the center of the sphere. GD is the diameter, which means AG and AD are radius.
On the other hand, remember that a tangent is a line that intersects the figure at only one point, otherwise, it would be a secant.
Therefore, segment BC is a secant and segment FE is tangent.
So, the right answer is segment FE.
ANSWER= 0.9772
STEP-BY-STEP EXPLANATION:
We are assuming that there is an underlying distribution of package weights,even though we don´t speciify the shape of that distribution.
Letting denote the ith package weight and S= we are trying to find P(S ≤ 1700)
We know that the distribution of S is approximately normal with mean nцХ and variance по²Х
S≈N( 100 * 15, 100 * 10² ) = N (1500.10000) (note that they gave us the standar deviation aove; variances add, so we need to square this). Finally,
P(S ≤ 1700) = P ( ≤ )
≈P (Z≤2) = 0.9772
