Answer:
2.a)31°
b)135°
3.a)72°
Step-by-step explanation:
2a) Angles in a straight line add up to 180°
180-62=118°
since in an isosceles triangle base angles are equal 62÷2=31°
b)sum of interior angles=180(n-2)
180(8-2)=1080°
each angle is 1080÷8=135°
3.a) Exterior angle=360/n
=360÷5=72° each

Um, I'm not sure how to explain, but watch a khan academy video on it
Answer:
61.1 m^ 2
Step-by-step explanation:
Area= L * B
= 4.7 * 13
= 61.1
you didn't tell wich program to use and did not include any pictures.
anyways, I graphed the function with desmos (free to use as app and on website)
so that u can see what the graph should look like.
variance based on the zoom is okay of course.
Answer:
-5
Step-by-step explanation:
Here are the steps to take in calculating the correlation coefficient:
Determine your data sets.
Calculate the standardized value for your x variables.
Calculate the standardized value for your y variables.
Multiply and find the sum.
Divide the sum and determine the correlation coefficient.
