Answer:
x = 33
<C = 81
Step-by-step explanation:
The sum of the angles of a triangle add to 180
x+ 2x+ 2x+15 = 180
Combine like terms
5x+15 = 180
Subtract 15 from each side
5x +15-15 =180-15
5x = 165
Divide by 5
5x/5 =165/5
x = 33
<C = 2x+15 = 2(33)+15 = 66+15 = 81
Answer:
•Lower confidence limit = $155.2109
•Upper confidence limit ,= $174.5891
Step-by-step explanation:
We are given:
U = 17
x' = $165.40
S.d = $21.70
a = 10℅ (90℅ confidence interval)
For s.d(x'), we have:
S/√u = 
= 5.2630
Therefore, S.E (x') = $5.2630
At a= 0.10 (90℅ confidence level)
and degree of freedom = 16 (17-1)
90℅ confidence interval all around sample mean, will be:
(x' ± 
; a S.E (x')
= (165.4±(174.6)(5.2630)
(165.5±9.189)
($156.2109, $175.5891)
Answer: ormally stated, Newton's third law is: For every action, there is an equal and opposite reaction
Step-by-step explanation: The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object.
Answer: 46
Step-by-step explanation:
You can simplify this using PEMDAS:
Parentheses
Exponents
Multiplication/division
Addition/subtraction
Move through the steps in that order.
In this case, the first two steps are absent, so multiply first:
20 - 16 + 42
Then, add and subtract:
46.
Step-by-step explanation:
To solve this you would use trigonometry. You would draw a triangle and mark the lower angle between the diagonal and horizontal line as 60. Then you would label the adjacent side as 50ft.
This means you are looking for the opposite and have the adjacent
To find the height you would do:
tan60 = Height÷50
Height = 50 tan60 = 86.6 feet (to 3 sf)
