The random variable X = the number of vehicles owned. Find the expected number of vehicles owned. Round answer to two decimal pl

Lelechka [254]

Answer:

The expected number of vehicles owned to two decimal places is: 1.85.

Step-by-step explanation:

The table to the question is attached.

$E(X) =$ ∑ $xp(x)$

Where:

E(X) = expected number of vehicles owned

∑ = Summation

x = number of vehicle owned

p(x) = probability of the vehicle owned

$E(X) = (0 * 0.1) + (1 * 0.35) + (2 * 0.25) + (3 * 0.2) + (4 * 0.1)\\E(X) = 0 + 0.35 + 0.50 + 0.60 + 0.4\\E(X) = 1.85$

The expected number of vehicles owned is 1.85.

If a 4 x 16 riangle has the same area as a square, what is the length of a side of the square

m_a_m_a [10]

Answer: $\bold{4\sqrt2}$

<u>Step-by-step explanation:</u>

$A_{triangle}=\bigg(\dfrac{1}{2}\bigg)b\times h$

$A_{triangle}=\bigg(\dfrac{1}{2}\bigg)4\times 16$

$=\bigg(\dfrac{1}{2}\bigg)64$

$=32$

$A_{square}= s^2$

$32 = s^2$

$\sqrt{32}=s$

$\sqrt{\underline{2\cdot 2}\cdot \underline{2\cdot 2}\cdot 2}=s$

$2\cdot 2\sqrt{2}=s$

$4\sqrt{2}=s$
