Fudgin [204]

Answer:

Infinitely many solutions

Step-by-step explanation:

$14-7p=-7(p-2)\\\\14-7p=-7p+14\\\\-7p=-7p\\\\p=p$

Therefore, $p\in \mathbb{R}$ , which means all real values of p are solutions

At a large company banquet for several thousand employees and their families, many of the attendees became ill the next day. The

yan [13]

Answer:

a. Yes. This provides convincing evidence that the true proportion of all attendees who ate the fish that got sick (80%) is more than the true proportion of all attendees who did not eat the fish that got sick.

b. The mistake here would have been the rejection of the Doctor's theory or hypothesis to the effect that more attendees who ate the fish got sick than those who did not eat the fish. This is a Type 1 error. A Type 1 error occurs when a null hypothesis is rejected when it is true. On the other hand, a Type II error occurs when the null hypothesis is accepted when it should be rejected. While a Type I error is equivalent to a false positive, a Type II error is equivalent to a false negative.

Step-by-step explanation:

Total number of attendees who ordered fish = 1,000

Sample size of the attendees who ate fish = 80

Number of attendees who ate the fish and got sick = 64 (80% or 64/80)

Sample size of attendees who did not eat fish = 60

Number of attendees who did not eat fish and got sick = 39 (65% or 39/60)

Every day the ocean has two low tides and two high tides. Function g represents the height, in feet, of the water level in a cov

Butoxors [25]

We can see from the question that we have the sine function, which is modeling the water level in a cove relative to the average sea level, and this function is given by:

$g(t)=4sin(\frac{\pi}{6}t)$

And we need to find the points where g(t) is equal to the average sea level.

1. To find it, we need to analyze the given function as follows:

2. Then we can say that the function has:

• An amplitude (the value from the ,midline of the function, in this case, x = 0,).

• The period of the function is given by:

$\begin{gathered} \text{ Period=}\frac{2\pi}{B} \\ \\ \text{ Period=}\frac{2\pi}{\frac{\pi}{6}}=2\pi(\frac{6}{\pi})=12 \\ \\ \text{ Period=}12 \end{gathered}$

3. These values can be seen as follows:

4. To find the points where g(t) is equal to the average sea level, we can see that the average sea level is represented by the midline, x = 0, and from the graph, we can see that these points are points on the x-axis, and they are (6, 0), and (12, 0) for the given graph:
