Step-by-step explanation:

Answer for the 1st Question,

Area of a cylinder can be calculated by,

Area of the cylindrical part =

Area of the parts that cover the open parts of cylinder =

Therefor Total are of the cylinder =

Area of the total cylinder =

                                          =

Therefor best estimate will be D) 923 in^2

Answer for the 2nd Question,

ABC is a triangle.

By Pythagorean theorem it says,

The distance from A to C = 6

The distance from C to B = 5

Therefor

Therefor Answer is D) Sqr 61

Answer to Question 3

To find the trend you can draw an imaginary line that fits the scatter plots.(I have attached a image drawing the imaginary lines)

Then the revenue can be calculated by calculating the area covered by the imaginary line drawn or area "under" the curve.

Area of the Store 1 =

Area of the Store 2=

Therefore Revenue from Store 1 = $8250

                 Revenue from Store 2 = $4400

Answer is A) Store 1  has more sales revenue

Answer for Question 4

You can straight away discard answer D because it is less than both 5/12 and 5/11.

Also you can discard Answer C because 25/264 is very small (less than 1/10=0.1)

, therefor this is not in between those two numbers.

Then it has to be

Answer is B)

Answer for question 6

The equation of a straight line is of the form

here m is the gradient and c is the intercept.

Find the intercept(c) by finding the y value when x value is 0, here it is +1.

Gradient (m) of the graph can be found by,

Therefor the equation of the graph is,

Answer is C

Answer for question 7

We can discard answer A because the value is close to 0.5

We can discard answer B because 3/17 is a very small value (0.17)

, This falls between the above 2 numbers.

Therefor answer is C

d is correct
