The measure of an inscribed angle in a circle is ______ the measure of the intercepted arc.
xxMikexx [17]

C. Half

<u>Explanation:</u>

An inscribed angle is an angle with its vertex on the circle and whose sides are chords. The intercepted arc is the arc that is inside the inscribed angle and whose endpoints are on the angle.

The Inscribed Angle Theorem states that the measure of an inscribed angle is half the measure of its intercepted arc.

Inscribed angles that intercept the same arc are congruent.

g People between the ages of 65 and 70 were studied to see if those who exercise more were healthier. One measure of health was
liubo4ka [24]

Answer:

If the person selected had high blood pressure, the probability that he or she did not exercise is P=0.643.

Step-by-step explanation:

We have a group of people between agss of 65 and 70.

They are divided in two groups regarding their amount of exercise: "none", "moderate" and "high".

The response variable is blood pressure, that was categorized as "normal"or "high".

Then,  we have the frequencies table as:

Amount of exercise          None    Moderate    High

Blood pressure High          54              23            7

Blood pressure Normal      86              76            32

We have to calculate the probability that, given that the person had high blood pressure, he or she did not exercise.

If the person had high blood pressure, it can be of the any of the 3 groups of exercise amount. There are 54 people with high blood pressure that did not exercise, 23 that did moderate amount of exercise, and 7 that did a high amount.

Then, the probability can be calculated dividing the amount of people that had high blood pressure and did not exercise, by all the people that have high blood pressure (regarding the amount of exercise):

P(N | HP)=\dfrac{54}{54+23+7}=\dfrac{54}{84}=0.643

If the person selected had high blood pressure, the probability that he or she did not exercise is P=0.643.

Algebra question I don’t get it because you usually have to multiple A by C but there is no C in the problem.
Misha Larkins [42]
Ok so basically, when you say multiply A by C, that is simplifying.

And in this case, you are factorising in this question. You turn back into brackets basically.

We have:
72x^2 - 32

x^2 = x squared

factorising means finding the factor of.

(Forget the x squared for the moment to make life easier)

Factors of 72:
1 and 72
2 and 36
3 and 24
4 and 18
6 and 12
8 and 9
(9 and 8 = it repeats so we stop there)

And then factors of 32:
1 and 32
2 and 16
4 and 8
(8 and 4 = repeats so we stop there)

Notice how we see 8 twice in both factors of 72 and 32, this means that we use 8 as the main number we are going to multiply each of the 2 numbers in the brackets by. This is because it is the biggest common factor - this is what we have!

This is what we would have:
8(9-4)

BUT, that is not the answer!
Keep in mind we have the x squared too

But, 32 doesn’t have it?!!

It would be:
8(9x^2 - 4)

Do you get it??

Try to simplify it! Does it equal to 72x^2 - 32?

(And I am so very sorry for the long explanation, once you get the hang of it, it makes sense. Hope my explanation helped) :)
