Answer:
m∠x = 119°
m∠y = 61°
m∠z = 119°
Step-by-step explanation:
Angle x:
- m∠x = 180° - 61° (sum of angles in a straight line)
- m∠x = 119°
Angle y:
- m∠y = 61° (Alternate interior angles)
Angle z:
- m∠z = 119° (Sum of angles in a line, corresponding angles)

Answer: The percent higher is 41.68%. If 49 planes were selected, 20 of them should be above 15 years.
To find the percent, we first need the z-score.
(15 - 13.5) / 7.3 = 0.21
Now, use a normal distribution table to find the percent above a score of 0.21. It will be 41.68%.
To find the number of 49 planes above this value, multiply 49 by 0.4168. You will have about 20.4 planes.
Step-by-step explanation:
x - 1 = - 3x - 14
Bringing like terms on one side
x + 3x = -14 + 1
4x = - 13
x = - 13/4
-6 yards
Step-by-step explanation:
6-12 = -6 yards
they lost a total of 6 yards
Answer:
I am assuming any number in between these two, so let's just say 6,550.
Step-by-step explanation:
If you count up from 6,534, you will eventually get to 6,550. If you continue to count up, you will eventually reach 6,565 which is bigger than 6,550.
