Answer:
The correct answer is option C
They are complementary angles
Step-by-step explanation:
From the figure we can see two angles <ABC and <LMN,
<u>To find the correct option</u>
From figure we get,
m<ABC = 20°° and m<LMN = 70°
m<ABC + m<LMN = 20 + 70 = 90°
Therefore <ABC and <LMN are complementary angles
The correct answer is option C
They are complementary angles
Answer:
1
Step-by-step explanation:
slope = (y' - y) / (x' - x)
Slope = (5 - (-1)) / 4 - (-2))
Slope = 6 / 6 = 1
Answer:
w≅8.46ft
Step-by-step explanation:
Data
focus=8
vertex=(0,0)
width=?
depth (y)=3ft
parabola equation: 
; then for V=(0,0), 
, be focus(f)=8in; 
→ 
we have that y=3ft then 
; but 1in≅0.083ft so 
→ x=±2.82, finally w=3*2.82≅8.46ft
Answer: the z score is - 5.33
Step-by-step explanation:
Since the results for the standardized test are normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = test reults
µ = mean score
σ = standard deviation
From the information given,
µ = 1700 points
σ = 75 points
We want to the Z-score test result of 1300 points.
For x = 1300,
z = (1300 - 1700)/75 = - 400/75 =
- 5.33
