Answer:
65°
Step-by-step explanation:
JM = JK (all sides of a rhombus are equal)
Angle JKM = 25° (isosceles triangle)
Angle JKL = 50° (consecutive angles of rhombus)
Angle MKL = 25° (angle subtraction)
Angle MLK = 130° (opposite angles of a rhombus)
Angle KLN = 50° (angles on a straight line)
Angle LKN = 40° (angle sum of triangle)
Angle MKN = 65° (angle addition)
Answer:
0.2916, 0.1488, 0.0319
Step-by-step explanation:
Given that a sign on the pumps at a gas station encourages customers to have their oil checked, and claims that one out of 10 cars needs to have oil added.
Since each trial is independent there is a constant probability for any random car to need oil is 0.10
Let X be the number of cars that need oil
A) Here X is BIN(4,0.1)
![P(X=1) = 4C1(0.1)(0.9)^3 \\= 0.2916](https://tex.z-dn.net/?f=P%28X%3D1%29%20%3D%204C1%280.1%29%280.9%29%5E3%20%5C%5C%3D%200.2916)
B) Here X is Bin (8, 0.1)
![P(x=2) = 8C2 (0.1)^2 (0.9)^6\\\\=0.1488](https://tex.z-dn.net/?f=P%28x%3D2%29%20%3D%208C2%20%280.1%29%5E2%20%280.9%29%5E6%5C%5C%5C%5C%3D0.1488)
C) Here X is Bin (20,5)
![P(x=5) = 20C5 (0.1)^5 (0.9)^{15} \\=0.0319](https://tex.z-dn.net/?f=P%28x%3D5%29%20%3D%2020C5%20%280.1%29%5E5%20%280.9%29%5E%7B15%7D%20%5C%5C%3D0.0319)
