Answer:

The formula is given by

\\ \rm\rightarrowtail V=\dfrac{1}{3}\pi r^2h

Here

  • V denotes to volume
  • r denotes to radius
  • h denotes to height

\sf volume \ of \ cone = \dfrac{1}{3} \pi r^2h     ** where "r" is radius and "h" is height **

\sf volume \ of \ cylinder=  \pi r^2h

\boxed{ \sf \tfrac{1}{3}} as it refers to the volume of cone being 1/3 of the the volume of cylinder

Hardest, example:

given height of cone is 69 km and radius is 48 km

using the formula:

\hookrightarrow \sf volume \ of \ cone = \dfrac{1}{3} \pi (48)^2(69)

\hookrightarrow \sf volume \ of \ cone = 52992\pi

\hookrightarrow \sf volume \ of \ cone = 166479.3 \ km^3

What is (3x+2​)+​(−4x+4)
gtnhenbr [62]

Answer:

-x + 6

Step-by-step explanation:

(3x + 2) + (-4x + 4)

Distribute + into the bracket (-4x + 4). When you do so, + sign becomes -

3x + 2 - 4x + 4

Rearrange the expression

3x - 4x + 2 + 4

-x + 6

Sodas in a can are supposed to contain an average 12 oz. This particular brand has a standard deviation of 0.1 oz, with an avera
hoa [83]

Answer:

The probability is  P(X <  12) =  0.99286

Step-by-step explanation:

From the question we are told that

        The population mean is \mu  =  12 \ oz

         The  standard deviation is  \sigma =  0.1 \ oz

          The sample mean is  \= x =  12.1 \ oz

          The sample size is  n = 6 packs

   

The standard error of the mean is mathematically represented as

              \sigma_{\= x } =  \frac{\sigma}{\sqrt{n} }

substituting values

            \sigma_{\= x } =  \frac{0.1}{\sqrt{6} }

            \sigma_{\= x } =  0.0408

Given that the can’s contents follow a Normal distribution then then  the probability that the mean contents of a six-pack are less than 12 oz is mathematically represented as

         P(X <  12) =  P ( \frac{X - \mu }{ \sigma_{\= x }}  < \frac{\= x - \mu }{ \sigma_{\= x }}  )

Generally  \frac{X  - \mu }{ \sigma_{ \= x }}   =  Z (The  \ standardized \  value \ of  \ X )

So

         P(X <  12) =  P ( Z < \frac{\= x - \mu }{ \sigma_{\= x }}  )

substituting values

       P(X <  12) =  P ( Z < \frac{12.2 -12 }{0.0408}  )

      P(X <  12) =  P ( Z < 2.45   )

From the normal distribution table the value of P ( Z < 2.45   ) is  

           P (Z < 2.45)0.99286

=>   P(X <  12) =  0.99286
