marissa [1.9K]

FORMULA:

  • Volume of cylinder = πr²h
  • Volume of sphere = 4/3πr³

ANSWER:

Volume of capsule = 4/3πr³ + πr²h

πr²(4/3r + h)

  • 3.14 × 2²(8/3 + 5.6)
  • 3.14 × 4(2.6 + 5.6)
  • 12.56(8.2)
  • 102.99 or 103 rounded.

Now, Density = 0.7mg/mm³

  • 0.7/103
  • 0.00679mg

A sales analyst listed the probabilities of profits and losses in dollars for a certain company. Find the mean for the probabili
kakasveta [241]

Answer: The mean for the probability distribution will be 69.25.

Explanation:

Since we given that

At\ x_1= -500 ,P(x) = 0.076\\

At\ x_2= -250,P(x)= 0.191\\

At\ x_3=0, P(x)= 0.265\\

At\ x_4=250 , P(x)= 0.316\\

At\ x_5=500 , P(x)= 0.152\\

As we know the formula for expectation of x i.e. known as mean for the probability distribution,

E(x)=x\sum_{1}^{5} P(x)

So, we  apply this formula in our case,

-500\times 0.076+(-250)\times 0.191+0\times 0.265+250\times 0.316+500\times 0.512=69.25

\mu = 69.25

Hence, the mean for the probability distribution will be 69.25.
