Answer:
Step-by-step explanation:
a) P(−1.36 ≤ z ≤ 1.38)
For z = - 1.36,
The corresponding probability from the normal distribution table is 0.08691
For z = 1.38
The corresponding probability from the normal distribution table is 0.9162
Therefore,
P(−1.36 ≤ z ≤ 1.38)
= 0.9162 - 0.08691 = 0.82929
b) P(−2.27 ≤ z ≤ 1.64)
For z = - 2.27
The corresponding probability from the normal distribution table is
0.0116
For z = 1.64,
The corresponding probability from the normal distribution table is
0.9495
Therefore,
P(−2.27 ≤ z ≤ 1.64)
= 0.9495 - 0.0116 = 0.9379
c) P(z ≤ 1.33)
For z = 1.33
The corresponding probability from the normal distribution is 0.9082
Therefore,
P(z ≤ 1.33) = 0.9082
d) P(z > −0.68) = 1 - P(z ≤ −0.68)
For z = - 0.68
The corresponding probability from the normal distribution is 0.2482
Therefore,
P(z > −0.68) = 1 - 0.2482 = 0.7518

Answer:
(b) 60°
Step-by-step explanation:
The sum of angles in a pentagon is 540°, so you have ...
90° +90° +150° +x +150° = 540°
x = 540° -480°
x = 60°
Graph the line using the slope and y-intercept, or two points.
