How do the arrows for +1 and -1 show both distance and direction?

Determine whether the given procedure results in a binomial distribution. If it is not binomial, identify the requirements that

masha68 [24]

Answer:

This procedure does not result in a binomial distribution because in each trial there are more than two possible outcomes, that is, this problem cannot be simplified as a yes or no question.

Step-by-step explanation:

For the binomial probability distribution being satisfied, two things are necessary:

1) The answer can only be two outcomes, two possibilities, for example, yes/no questions.

2) The probability of a success(an answer) on each trial must be the same. That is, if we are going to survey 100 people if they are Buffalo Bills fans, they will answer yes or no, and each of those 100 people will have the same probability of being a Buffalo Bills fans.

In this problem, we have that:

Surveying 20 college students and recording their favorite TV show.

There is infinite possibilities for each answer. One can answer Narcos, other Monday Night Football, other Sportscentre, and so it goes.

So this procedure does not result in a binomial distribution because in each trial there are more than two possible answers, that is, this problem cannot be simplified as a yes or no question.

If for example, we asked the 20 students if Monday Night Football was their favorite show, then they could answer only yes or no, so it would be a binomial procedure.

End of day/Distance from home

charle [14.2K]

Answer:

$\large \boxed{\text{B) 374 mi/day}}$

Step-by-step explanation:

The average rate of change from one point to another is the slope of the straight line joining the two points.

$\text{slope} = \dfrac{ y_{2} - y_{1}}{ x_{2} - x_{1}}$

From Day 1 to Day 3, your points are (1, 383) and (3, 1132).

$\text{Slope} = \dfrac{1132 - 383 }{3 - 1} = \dfrac{749 }{2} = \textbf{374 mi/day}\\\\\text{The average rate of change from Day 1 to Day 3 was $\large \boxed{\textbf{374 mi/day}}$}$

The graph below shows the rate of change from Day 1 to Day 3 as a black line. It appears from the graph that Adam and his dad kept the same rate of change for the whole trip.

"The number of blue markers in a drawer is 4 more than twice the number of red markers."

Elena-2011 [213]

Answer:

b=2r+4

Step-by-step explanation:

I don't think that you can do this using only one variable because there are two unknown amounts. Blue (b) is Red (r) multiplied by 2 plus 4 more, so the expression is b=2r+4.

1. What is the circumference of a circle with a radius of 3? (1 point)

4vir4ik [10]

1. $6 \pi$
This is because
$c= \pi d \\ 
c= 6 \pi$

2. $9 \pi$
because
$A= \pi r^{2} \\ 
A = \pi (3)^{2} \\ 
A = 9 \pi$

3. $4 \pi$
$C= \pi d \\ 
C= 4 \pi$

4. $4 \pi$
$A = \pi r^{2} \\ A = \pi (2)^{2} \\ A = 4 \pi$

Can't really answer the last 2 w/o the figures
