Answer: the z score is - 5.33

Step-by-step explanation:

Since the results for the standardized test are normally distributed, we would apply the formula for normal distribution which is expressed as

z = (x - µ)/σ

Where

x = test reults

µ = mean score

σ = standard deviation

From the information given,

µ = 1700 points

σ = 75 points

We want to the Z-score test result of 1300 points.

For x = 1300,

z = (1300 - 1700)/75 = - 400/75 =

- 5.33

The diameter of a circle has the endpoints of (2, 5) and (-8, 29). Find the center and radius of the circle. ANSWERS ATTACHED, d
lilavasa [31]

Answer:

\mathrm{Center\:\:}= (- 3,17)\\\mathrm{Radius\:\:}=  13

Step-by-step explanation:

Remember that the center of the circle would be equidistant from the given points that lie on the circle.

By determining the diameter through the distance of the given points, we can determine the radius by dividing this distance by 2. And by determining the radius we can determine the center of the circle. Let's do it.

\mathrm{Distance\:between\:}\left(2,\:5\right)\mathrm{\:and\:}\left(-8,\:29\right) = \sqrt{\left(-8-2\right)^2+\left(29-5\right)^2} = 26

\mathrm{Radius\:\:}= 26 / 2 =13

So now that we know the radius is 13 units, we can eliminate answer choice(s) # 2 and # 4. That leaves us with the first and third answer choices. The center being (5,12) is not likely, as most of the circle lies in the 2nd quadrant. That is presumably why (- 3,17) is more predictable. Our answer is the third option.

Answer:

interpretation of p-value

With the information from the exercise we can deduce that the number of adults in North America who are going to reduce the costs of medical care, considering this as a national priority, are within a probability of 0.045, however the real data tells us that 0.68 of adults are in favor of this reduction
