Answer:

1131 cubic inches.

Step-by-step explanation:

The front side of the figure contains a rectangle and a semicircle.

Area of rectangle is

A_1=length\times breadth

A_1=11\times 12

A_1=132\text{ in}^2

Radius of semicircle is

r=17-11=6\text{ in}

Area of semicircle is

A_2=\dfrac{1}{2}\pi r^2

A_2=\dfrac{1}{2}\pi (6)^2

A_2\approx 56.55

Area of front side is

A=A_1+A_2=132+56.55=188.55\text{ in}^2

Let front side is the base of prism and height is 6 in. So, volume of given figure is

V=\text{Base area}\times height

V=188.55\times 6

V=1131.3

V\approx 1131\text{ in}^3

Therefore, the required volume is 1131 cubic inches.

The probability distribution for the random variable x follows. x f(x) 20 0.20 25 0.15 30 0.30 35 0.35 (a) Is this probability d
Damm [24]

Answer:

(a) The probability distribution is valid.

(b) The probability that x = 30 is 0.30.

Step-by-step explanation:

The probability distribution of the random variable <em>X</em> is:

<em>    x</em>:  20   |  25  |  30   |   35

f (<em>x</em>): 0.20 | 0.15 | 0.30 | 0.35

(a)

The properties of a probability distribution are:

  1. 0 ≤ P (X) ≤ 1
  2. ∑ P (X) = 1

All the probability value are more than 0 and less than 1.

Compute the sum of all the probabilities as follows:

\sum P(X)=0.20+0.15+0.30+0.35=1

The sum of all probabilities is 1.

Thus, the probability distribution is valid.

(b)

Consider the probability distribution table.

The probability of <em>X</em> = 30 is,

P (X = 30) = 0.30.

Thus, the probability that x = 30 is 0.30.

Question 10 (1 point) Solve for x. 1/2+x/6=4/3
jek_recluse [69]

Answer:

The value of x for the given expression is 5 .

Step-by-step explanation:

Given expression as

\dfrac{1}{2} + \dfrac{x}{6} = \dfrac{4}{3}

Now, arrange the equation

So, \dfrac{x}{6} = \dfrac{4}{3} - \dfrac{1}{2}

<u>Taking L.C.M on right hand side </u>

Or,  \dfrac{x}{6} = \dfrac{8 -3}{6}

Or,  \dfrac{x}{6} = \dfrac{5}{6}

Or, x = \frac{5\times 6}{6}

∴  x = 5

So, The value of x = 5

Hence,The value of x for the given expression is 5 . Answer
