180 degrees in a triangle therefore you will subtract 54 and 79 from 180 which then gives you the answer --47--
do you understand how to do it now ?
Answer: 0.0129
Step-by-step explanation:
Given : Mean :
Standard deviation :
Sample size :
Let X be the random variable that represents the age of of the fleets.
Z-score :
For x = 14
By using standard normal distribution table , the probability that the average age of these 40 airplanes is at least 14 years old will be
Hence, the the probability that the average age of these 40 airplanes is at least 14 years old =0.0129

Answer:
m∠BEC = 65°
m∠DEC = 115°
m∠DAE = 78°
m∠ECD = 40°
m∠BAD = 118°
m∠ADC = 62°
Step-by-step explanation:
m∠BEC = 65°
Opposite angles formed by intersecting lines are congruent
m∠DEC = 180 - 65 = 115°
A straight line has a degree measure of 180
m∠DAE = 78°
Opposite interior angles of two parallel lines cut by a transversal are congruent
m∠ECD = 180 - [m∠DEC + 25] = 40°
Sum of angles inside triangle ECD has a measure of 180
m∠BAD = 78 + m∠ECD = 118°
Opposite angles of a parallelogram are congruent
2(m∠BAD) + 2(m∠ADC) = 360
118 + m∠ADC = 180
m∠ADC = 62°
Sum of angles inside a parallelogram = 360°
Answer:
The sequence is geometric
Step-by-step explanation:
The sequence is being multiplied by a common ratio, therefore it is geometric.
