The answer is D. 2+1/5×(7/12+3)
Answer:
.3
Step-by-step explanation:
The probability distribution in the second row simply shows the probabilities for each number in the first row.
To find the probability that x is between -5 and 5, you can add the probabilities -5 < x < 5.
P(-5) = 0.15
P(0) = 0.05
P(5) = 0.1
0.15 + 0.05 + 0.1 = 0.3
Answer:
x = 76°
z = 14°
y = 42°
Step-by-step explanation:
48 + 2x = 180° because these three makes a straight line
2x = 180 - 48
2x = 132
x = 76°
x + z = 90° because these two angles are complementary angles since we know the value of x
76 + z = 90°
z = 90 - 76
z = 14°
48° + y = 90° because these two angles are complementary angles
y = 90 - 48
y = 42°
