Answer:
?=91 degrees.
Step-by-step explanation:
There is no x- I'll find ? though.
So, angles in a triangle must equal 180.
180-29-62=89. The last angle in the triangle is 89 degrees.
A straight angle is equal to 180 degrees. ? + 89=180.
180-89=91.
?=91 degrees.
Hope this helped!
8(51) = 8(50 + 1) = 8(50) + 8(1) = 400 + 8 = 408
Answer:
C≈27 feet
Step-by-step explanation:
A=πr²
A/π=r²
√A/π =r or –√A/π=r (refused)
then r =√(A/π) =√(58/π) =4.297829403 feet
C=2πr=2π(4.297829403)=27.00405856≈27 feet
Answer:
Estimation by inspection is better than trying to determine the line of best fit exactly
i) For a scatter plot : The use of estimation by inspection
ii) For a straight line graph : The exact determination method
Step-by-step explanation:
To create lines of best fit the estimation by inspection is better than trying to determine the line of best fit exactly .
This is because line of best fit only shows the trend of the data and in most cases it doesn't have to start from origin.
Scenarios :
i) For a scatter plot : The use of estimation by inspection
ii) For a straight line graph : The exact determination method
Your answer is 38 I hope its correct :)
