Answer: option c

Step-by-step explanation:

margin of error = critical value × s/√n

Where s = sample standard deviation = 0.58, n = 53

The critical value = 1.96 ( this is the critical value for a two test test corresponding to a level of significance of 5%)

By substituting the parameters, we have that

Margin of error = 1.96×0.58/√53

Margin of error = 1.96 × 0.0796

Margin of error = 0.156 ~ 0.16

Tell whether the ordered pair is a solution to the equation please show how you solve it.
Orlov [11]

Answer:

The ordered pair is not a solution as both sides of the equation do not equal each other.  

Step-by-step explanation:

(3,2);  x + 6y = 13

(3) + 6(2) = 13

3 + 12 = 13

15 = 13

What is the volume of a cylinder with a radius of 10cm and a height of 30cm
lys-0071 [83]

Answer:

9,424.8 cm^3

Step-by-step explanation:

V = A of circle x h

= πr^2 x h

=(3.1416)(10)^2 x 30

=(3.1416)(100) x 30

=314.16 x 30

=9429.8

In the following shape, two semicircles
Andrei [34K]

Answer:

The length around the figure in terms of r is 2r (\pi + 4).

Step-by-step explanation:

The perimeter of an object is the total length of the boundary of the object.

The figure consists two similar semicircle and a rectangle.

Adding the two semicircles, a complete circle is formed. The circumference of a circle = 2\pir.

The rectangle has a length which is twice its height.

     i.e l = 2h

But,

     r = \frac{h}{2}  (the diameters of the semicircles equal the height of the rectangle)

   ⇒ h = 2r

Thus, one side length of rectangle = 2 × 2r        (l = 2 × h)

                                                          = 4r

The length around the figure in terms of r is:

                   = 2\pir + 4r + 4r

                   = 2\pir + 8r

                   = 2r (\pi + 4)

The length around the figure in terms of r is 2r (\pi + 4).
