Answer is A, all interior angles and exterior sun must be 360. those are interior angles so they have to add up to 180
Answer: z equals 0.60 minus 0.72 all over the square root of the quantity 0.72 times 0.28 over 80
Step-by-step explanation:
let p be the population proportion of students complete their homework on a daily basis.
As per given , we have
p= 0.72
sample size : n= 80
Sample proportion : 
Test statistic for proportion:

i.e.

i.e.

That is , z equals 0.60 minus 0.72 all over the square root of the quantity 0.72 times 0.28 over 80
Answer with explanation:
Properties of Rectangle
1. Opposite sides are equal and parallel.
2. Diagonals are equal and bisect each other.
3. Adjacent Sides are Perpendicular to each other.
→If two lines are parallel their slopes are equal and if two Lines are perpendicular, their product of slopes is -1.
→A Rectangle is a Quadrilateral also.
→Adjacent sides are perpendicular ,so , their slopes can't be equal.Product of their slopes should be equal to ,-1.
⇒Slope of AB × Slope of BC = -1
⇒Also, Slope of AB × Slope of BC = -1
Slope of AB × Slope of AD = -1
⇒ Slope of AD × Slope of CD = -1
Slope of CB × Slope of CD = -1
Option B And Option C
are statement which proves that polygon ABCD is not a rectangle.

I really didn't understand the question or what to do, but I tried.
Step-by-step explanation:
Answer: The required point is A(6, 3) in the attached graph.
Step-by-step explanation: We are to find the point on the given graph that shows the price of 6 ounces of cheese.
The formula to be used is given by

Given that,
when x = 2 then y = 1. That is, price of 2 ounces of cheese is $1.
when x = 7 then y = 3.5. That is, price of 7 ounces of cheese is $3.5.
when x = 14 then y = 7. That is, price of 14 ounces of cheese is $7.
Therefore, these points satisfy the given relation (i).
Hence, if x = 6, then from equation (i), we have

Thus, the price of 6 ounces of cheese is &3. This gives that the required point is A(6, 3) on the graph attached below.
