avanturin [10]

Answer:

The correct answer is "1668". A further solution is provided below.

Step-by-step explanation:

According to the question,

Estimated proportion,

\hat{p} = \frac{574}{1007}

  =0.57

Margin of error,

E = 0.02

Level of confidence,

= 90%

= 0.90

Critical value,

Z_{0.10}=1.65

Now,

⇒  0.02=1.65\times \sqrt{\frac{0.57\times 0.43}{n} }

 0.0004=2.7225\times \frac{0.2451}{n}

         n=\frac{2.7225\times 0.2451}{0.0004}

             =1668.21

or,

         n \simeq 1668

Which represents the inverse of the function f(x) = 4x?
Dmitry_Shevchenko [17]
F (x) = 4x    ⇒    y = 4x 
                               ↓
                           x = 4y     Divide by 4 on both sides
                               ↓
                          x / 4 = y   ⇒   Inverse function = x / 4

Answer:

11a.  m <1 = 131          12a.  m <1 = 42

11b.  m <2 = 49          12b.  m <3 = 75

11c.  m <3 = 131          12c.  m <4 = 42

11d.  m <4 = 49          12d.  m <5 = 63

11e.  m <5 = 131         12e.  m <6 = 75

11f.  m <6 = 49          12f.  m <7 = 105

11g.  m <8 = 49          12g.  m <8 = 75

11h.  m <9 = 92          12h.  m <10 = 75

11i.  m <10 = 88          12i.  m <11 = 42

11j.  m <11 = 92          12j.  m <12 = 138

11k.  m <12 = 88         12k.  m <13 = 42

11l.  m <13 = 92         12l.  m <14 = 138

11m. m <14 = 88

11n.  m <15 = 92

Step-by-step explanation:

When lines are parallel to  each other than:

A cylinder has a radius of 5 and height of 3. what is the volume
Lapatulllka [165]

Answer:

236 cubic units (to 3 significant figures)

Step-by-step explanation:

volume of a cylinder = \pir²h   (where r = radius and h = height)

Therefore, volume = \pi x 5² x 3

                               = \pi x 25 x 3

                               = 75\pi

                               = 236 cubic units (to 3 significant figures)
