Answer:
The answer is option B. 240
Equation that fits best in data is 
.Although there are no options , kindly match this equation to options available!
<u>Step-by-step explanation:</u>
We are given a graph with y & x-axis , with 4 points given and best fit for data can be found out by joining points . On joining points , we see that best fit is a line . General equation of a line is : 
,
where m = slope of line & c = intercept.
Let's calculate slope m :
Consider any two given points , let's have ( 4,0) & (3,30) :
Slope = m
⇒ m = 
⇒ m = 
⇒ m = 
So , equation now becomes :
⇒ 
at x = 0 we have y = 4
Therefore, equation that fits best in data is .Although there are no options , kindly match this equation to options available!
Answer:
72°
Step-by-step explanation:
Let the 2 equal angles be x then the third angle is x + 18
The sum of the 3 angles in a triangle = 180°, thus
x + x + x + 18 = 180, that is
3x + 18 = 180 ( subtract 18 from both sides )
3x = 162 ( divide both sides by 3 )
x = 54
Hence
the largest angle = x + 18 = 54 + 18 = 72°
Step-by-step explanation:
well you didnt put the A B C or D answers but the answer is any ordered pair where the 8 is the y axis which is the second number in the ordered pair. Ex: (4,8)
NOT Ex: (8,4)
The square root of 36 is 6 so just write
2 × (6) +9
so
12 + 9
= 21
