Answer:
1/15
Step-by-step explanation:
Hillis has 4/6 of a bag of toys and he needs to split it into 10 boxes. This means that each box will have 4/6/10= 1/15 of an original bag of toys.
I hope this helps! Have a wonderful day!
The line is 7 units long. Add the two equations together and set equal to 7:
7x-1 + 2x-1 = 7
Combine like terms:
9x-2= 7
Add 2 to both sides:
9x= 9
Divide both sides by 9:
X= 1
The height of the tree which is the opposite side of the right triangle is 145 meters.
<h3>How to find height when given angle of elevation?</h3>
The angle of elevation is 36 degrees.
The situation forms a right angle triangle.
Therefore,
base of the triangle = 200 m
Hence, using trigonometric ratios,
tan 36 = opposite / adjacent
tan 36 = x / 200
x = 200 tan 36
x = 200 × 0.726542528
x = 145.308505601
x = 145.31 m

Answer:
Z=120°
x=28°
Step-by-step explanation:
z+60°=180°(co-interior angle )
z=6x-48°(Vertically opposite angle)
Answer: Option D : All of the above.
Step-by-step explanation:
(1) The Cumulative Link Models assumptions can be summarized as, conditional on (x1, … xk)
(2) Whether normality of error u, and thus normality of y conditional on (x1, … xk) can be assumed, is an empirical matter
and (3) Normality of error u translates into normal sampling distributions of the OLS estimators are all correct statements describing linear regression.
