Answer:
x > 4 or 4<x
Step-by-step explanation:
12<8+x
You can rewrite it for easier look:
8+x>12
Suvtract 8 from both side:
8+x-8>12-8
0+x > 4
x > 4 or 4<x

Answer:
a) 0.2347, 0.0007
b) 1.30
c) 0.63
Step-by-step explanation:
Given –
Mean = 73.4
Sigma = 4.7
Probability that the speed is greater than 70 is
P (X>70) = P (z> (70-73.4)/4.7) = P (z>-0.72) = 0.7653
a) The probability that a car is not speeding = 1 - 0.7653 = 0.2347
The probability that all 5 cars are not speeding = (0.2347)5 = 0.0007
b) E (X) = 1/p = 1/0.7653 = 1.30
c) Standard deviation = Sqrt (1-p/p) = (1-0.7653)/0.7653 = 0.63
Answer:
x = 48
y = 21
Step-by-step explanation:
To find the value of x and y, using the definition of supplementary angles, create an equation to find x and y as follows:
Finding y:-
(supplementary angles definition)
Solve for y
Collect like terms
Finding x:-
(supplementary angles definition)
Solve for x
Combine like terms
