A. X ~ N(66, 6.25)
b.
Using a standard normal probability table to find probability values for the z-scores, we get:
P(65 < X < 69) = 0.1554 + 0.3849 = 0.5403
c. z= 0.524 and -0.524
1.31 = X - 66
X = 67.31
When z = -0.524, X = 64.69.
P(64.69 < X < 67.31) = 0.4
Answer:
Step-by-step explanation:
So we have the equation:
Combine like terms:
Add:
Add 16 to both sides:
Divide both sides by 8:
So, our answer is 24.5 :)
Answer:

False.
Option (2).
True.
Option (3).
False.
Option (4).
Both the sides are not equal.
False.
2500/5=500 this is the unit rate
The quadrilateral which can be considered as a "Parallelogram" or "Not necessarily a parallelogram. are second and fourth figure.
"The correct figures are (b) and (d)
<h3>What is a parallelogram?</h3>
A parallelogram is a quadrilateral with opposite sides parallel (and therefore opposite angles equal).
- The first one is a parallelogram because, the angle are shown are alternate interior angles which defined between two parallel lines.
- The second one is not a parallelogram because, the angle are shown are alternate interior angles which should defined between two parallel lines. But there are no parallel lines.
- The third one is not a parallelogram because, the parallelogram have opposite angles are equals not the adjacent angle.
Here the adjacent angle are given equal.
- The fourth one is a parallelogram because, the opposite side of parallelogram are equal and parallel to each other.
