The reflection of point S across the y-axis is point

1. Here are the four steps of the statistical process in correct order:
1) Plan - Form a question that can be answered by data.
2) Collect data - Design and implement a plan that collects data.
3) Process - Analyze the data using graphical and numerical methods.
4) Present and discuss - Interpret and compare the data.
So your answer is the last option.

2. I am definitely sure that Edgar wrote a statistical, because every neighbor can give a different answer. A statistical question is the question which you don't expect to get only one answer. Instead of that you will get a variety of different answers.

3. According to what I've mentioned before, the only statement which shows a characteristic of a statistical question is: There can be variability in the answers to the question.

4. I am completely sure that this one is statistical question: How many hours do you spend each week training for a sports league? Because it could be answered with variability.

5. The only statistical question in his survey is: How many hours do you spend at the food court each month?. Because it gives him more different answers for his survey.

Two containers hold several balls. Once a second, one of the balls is chosen at random and switched to the other container. Afte

natka813 [3]

Answer:

(a) 8 balls

(b) 4 balls

Step-by-step explanation:

Let

$N \to$ Number of balls

For a box, the probability that there are N balls in it is:

$Pr = 0.5^N$

For 2 boxes, it is:

$Pr = 2 * 0.5^N$

From the question, we have:

$\frac{80}{10000} \to$ Favorable outcome

To solve for N, we have:

$2 * 0.5^N = \frac{80}{10000}$

$2 * 0.5^N = 0.008$

Divide both sides by 2

$0.5^N = 0.004$

Take log of both sides

$\log(0.5^N) = \log(0.004)$

Apply law of logarithm

$N\log(0.5) = \log(0.004)$

Make N the subject

$N = \frac{\log(0.004)}{\log(0.5)}$

$N =7.966$

Approximate

$N = 8$

Solving (b): Balls in one of the two boxes.

Here, we assume that each ball will have almost the same number of balls at a given instance;

Hence, we have:

$Balls \approx \frac{N}{2}$

$Balls \approx \frac{8}{2}$

$Balls \approx 4$

4 balls in each box

Can someone please help?

Standard form means, move the variables to the left-hand-side and leave the constant all by herself on the right-hand-side, usually sorting the variables, so"x" goes first.

now, there's a denominator, we can do away with it, by simply multiplying both sides by the denominator, so let's do so,

$\bf y=-\cfrac{2}{3}x+7\implies \boxed{3}\cdot y=\boxed{3}\cdot \left( -\cfrac{2}{3}x+7 \right)\implies 3y=-2x+21
\\\\\\
\stackrel{standard~form}{2x+3y=21}$
