Ends of a diameter: (-9, -16) and (3,0)

lbvjy [14]

Answer:

One example is the equation:

2x + 6 = 4x/2 + 12/2

To solve this, we need to transpose like terms to the same side.

2x - 4x/2 = 12/2 - 6

2x - 2x = 6 - 6

0 = 0

Since both sides are zero, it means that the equation has infinite number of solutions.

Answer:

Step-by-step explanation:

Take the mean of each row in the accidents reported column so for example 0-4 would be 0+4/2 = 2

Then times it by the frequency which in this case is 15:

2 x 15 = 30

Do this for each rows and then add it all up:

30 + 28 + 120 + 34 = 212

Then divide it by number of row which in this case is 4:

212/4 = 53

Consider the probability that exactly 20 out of 309 people will get the flu this winter. Choose the best description of the area

noname [10]

Answer:

The distribution of proportion of people who will get the flu this winter is N (0.065, 0.014²).

Step-by-step explanation:

Let X = number of people who will get flu this year.

The sample selected is of size, n = 309.

The number of people who will get flu in this sample is, x = 20.

Compute the sample proportion of people who will get flu as follows:

$p=\frac{x}{n}=\frac{20}{309}=0.065$

The random variable X follows a Binomial distribution with parameters n = 309 and p = 0.065.

The sample size is quite large, i.e. n = 309 > 30.

And the probability of success is low.

So the Normal approximation to Binomial can be used to approximate the distribution of sample proportion is:

np ≥ 10
n(1 - p) ≥ 10

Check whether the conditions are fulfilled or not as follows:

$np=309\times 0.065=20.085>10\\n(1-p)=309\times (1-0.065)=288.915>10$

Hence, the conditions are fulfilled.

The sampling distribution of sample proportion is:

$p=N(p, \frac{p(1-p)}{n})$

Compute the mean and variance as follows:

$Mean=p=0.065\\Variance=\frac{p(1-p)}{n}=\frac{0.065(1-0.065)}{309}=0.014^{2}$

Thus, the distribution of proportion of people who will get the flu this winter is N (0.065, 0.014²).
