Answer:
≈ 13.9
Step-by-step explanation:
Calculate the distance d using the distance formula
d = 
with (x₁, y₁ ) = K(9, 2) and (x₂, y₂ ) = L(- 3, 9)
d = 
= 
= 
= 
≈ 13.9 ( to the nearest tenth )
Answer:
16
Step-by-step explanation:
If they are parallel then the 2 angles are congruent, so
8x + 14 = 12x - 50
64 = 4x
16 = x
Answer: 95% confidence interval would be (1341.2,1458.8).
Step-by-step explanation:
Since we have given that
n = 64
Average = 1400
Standard deviation = 240
We need to find the 95% confidence interval for SAT scores.
So, z = 1.96
So, Interval would be

Hence, 95% confidence interval would be (1341.2,1458.8).
Answer:

Step-by-step explanation:
A quadrilateral (having four sides) has a sum of interior angles equal to 360 degrees.
Since, A Parallelogram has 4 sides so it is also a quadrilateral which means that the sum of its interior angles equal 360 degrees.
