1. If a car must have at least 2 passengers in order to be in the carpool lane on this highway, what is the probability that a r

andomly selected car is allowed to be in the carpool lane?
P(x>2) .15+.10+ .3+ .2= .30

2. Find the probability that a randomly  selected car on this highway has fewer than 4 occupants.

P(x<4)= p(x<3)=
.70+ .15+ .10= .95


3. Calculate the mean of this probability distribution.  Click on the tool "Insert Math Equation" in the toolbar above to write your answers using correct notation and round it to one more decimal than is contained in the data (type out your calculations).

E(x) is

1(x) p(1) + 2p(2) + 3p(3)+ 4p(4)+ 5p(5)
.70+.30+.30+.12+.10
=1-52



4. Explain what your answer to #3 means in the context of this problem.

Mean is the expected value and measure of tendency following is the probability of distribution

5. What shape would the probability histogram of this probability distribution have (you do not have to actually create or embed the histogram)?  Explain the meaning of this in context.  In other words, what does this tell you about the driving habits of most drivers on this highway?

Most drivers have more than 2 passengers while driving in the carpool lane on the freeway​

Tasha eats half her snack and gives the other half to her two best friends for them to share equally. What portion of the whole
kolbaska11 [484]

Answer: The answer to the question "What portion of the whole snack does each friend get?" is: Tasha 1/2 of the snack, her friends 1/4 of the snack each one.

Step-by-step explanation:

The complete snack is 1. If you say that Tasha eats half of the snack that means that you must divide 1 in 2 parts. Then, that gives us 1/2 left.

Tasha gives 1/2 of the snack to her 2 friends and shares it equally. That means that again you must divide it in 2 parts. That gives us:

1/2 ÷ 2 = 4

When you divide a fraction (1/2) into an entire number (2) you must take into account that there is a 1 below the entire number (2). Having that in mind, the next step is to multiply in cross: the 1 above the 2 (1/2) will multiply the 1 below the 2 (2/1), And the 2 below the 1 (1/2) will multiply the 2 above the 1 (2/1). The result of the first multiplication will be the number above the fraction that means 1, and the result of the second multiplication will be the number below the fraction that means 4. The final result is 1/4 (look in the picture attached).

To conclude, each of her friends received 1/4 of the snack.

Attached you may find a picture of the parts of the snack that each friend received.

koban [17]

Answer:

(a+b)^2 = a^2 + 2ab + b^2

(a-b)^2 = a^2 - 2ab + b^2

(a-b)(a+b) = a^2 - b^2
