Answer:

C, 3

Step-by-step explanation:

By creating a best line of fit you can get the sets of points (16,50) and (12,40)

Using these to find the slope we can get $\frac{40-50}{12-16} =\frac{-10}{-4}$

-10/-4 is 2.5 The best approximation would be C, because if you round it up to the nearest number you would get 3.

List the integers satisfy the inequality -1 less than 2x - 5 less or equal to 5<br>

Ilya [14]

Answer:

integers are { 3 , 4 , 5 }

Step-by-step explanation:

- 1 < 2x - 5 ≤ 5

- 1 + 5 < 2x - 5 + 5 ≤ 5 + 5 [ adding by 5 ]

4 < 2x + 0 ≤ 10

4 < 2x ≤ 10

2 < x ≤ 5 { divide by 2 ]

Therefore, integers are { 3 , 4 , 5 }

What is the total surface area of a cylindrical tank having

UkoKoshka [18]

Answer:

Could be C) or D) None of these, 29688.05cm^2

Step-by-step explanation:

Did the question to round off to any numbers?

Formula for cylinder's T.S.A: 2 π r h + 2 π r^2

Diameter= 2 x radius

Radius = 70cm / 2 = 35cm

Height -> need to convert m to cm -> 100cm

Substitute these values into the formula:

2 x π x 35 x 100 + 2 x π x (35)^2 = 29688.05cm^2
