Sum of all angles of a triangle = 180°
So,
angle E + angle O + angle C = 180°
=> 53° + 77° + C = 180°
=> 130° + angle C = 180°
=> angle C = 180° - 130°
=> angle C = 50°
We have that
x²<span>-20x
</span><span>Group
terms that contain the same variable
</span>(x²-20x)
Complete
the square
(x²-20x+10²)------> (x-10)²
the answer is
the number must be 100
Answer:
Y=X
Step-by-step explanation:
It depends on the context. No number besides 0 is given, so it can't really be the other ones with numbers.
Answer: Medians, Less
Part A
Use the measures of center from the box plots to make an inference about the data. Use the drop-down menus to explain your answer.
Based on the <u><em>medians</em></u>, the plants in Group A grew
<em><u>less</u></em><em><u> </u></em>on average, as compared to the plants in Group B.
Part B Answer: Greater, Less
The range and IQR are <u>greater</u>
in Group B as compared to Group A, so there is <u>less</u> variability in the growth of plants in Group B.
A ) The rate at which rumor spreads speed up over time. If t increases, also N(t) increases, because 300 is divided by the smaller number.( Correct )B ) 1 = 300 / ( 1 + 299 · e^(-0.36 · 0 ) ) 1 = 300 / ( 1 + 299 · 1 ) 1 = 300 / 3001 = 1 ( Correct )C ) 100 = 300 / ( 1 + 299 · e^(-0.36 · 14 ) )100 = 300 / ( 1 + 299 · 1/154.47 )100 = 300 / 2.93565100 ≈ 102.192 ( Correct ) - approx. 14 minutes
D ) N = 300 / ( 1 + 299 · e^(-∞) )N = 300 / ( 1 + 299 · 0 ) N = 300 / 1 = 300299 people are enclosed space ( Not correct )Answer:True statements are: A ) , B ) and C ) .
