In 2012, researchers working with a very large population of health records found that 9.3% of all Americans had diabetes (sourc

e: National Diabetes Statistics Report, 2014). Suppose a medical researcher randomly selects two individuals from a large population. Let A represent the event "the first individual has diabetes." Let B represent the event "the second individual has diabetes." True or false? A and B are independent events.

Answer:

False. These events are dependent.

Step-by-step explanation:

A represent the event "the first individual has diabetes."

B represent the event "the second individual has diabetes."

The probability that the second individual has diabetes changes according to the probability that the first individual has diabetes.  Therefore these events are dependent.

What is the length of AB?
makkiz [27]
The radius of the circle is given to be r = 14.5

Let the center be O. So OB is the radius = 14.5

We can draw a triangle as shown in the image below. We have a right angled triangle. We know the hypotenuse and the base, we need to find the perpendicular side. This can be done using the Pythagorean theorem.

So, we can write:

(14.5)^{2}=10^{2}+OA^{2} \\  \\ &#10;OA^{2}=110.25 \\  \\ &#10;OA=10.5

Thus, the measure of OA = 10.5

OB = OA + AB

14.5 = 10.5 + AB
⇒
AB = 4

I need help on this question plz
Gelneren [198K]

Hello!

The mean is the average. The median is the middle number of the data set, in terms of quantity. The mode is the number that appears the most. The range is the difference between the largest and smallest numbers in the set.

Therefore, our answers are below.

Range: Difference between largest and smallest data piece.

Median: Middle value of a set of data

Mode: most commonly occurring number(s)

Mean: the sum of the data divided by the quantity of the data items.

I hope this helps!

I need help with this is my last one
Stells [14]

Answer:

1. Quadrant 2

2. Quadrant 1

3. Quadrant 2

4. Quadrant 4

5. Quadrant 4

6. Quadrant 2

7. Quadrant 2

8. Quadrant 3

Step-by-step explanation:

For this problem, we just need to follow the pattern of positive and negatives associated with each quadrant.

The first quadrant (+, +)

The second quadrant (-, +)

The third quadrant (-, -)

The fourth quadrant (+, -)

Using these patterns we can state what order pair correlates to which quadrant.

(-2.5, 2.1) --> Q2

(1/2, 3/4) --> Q1

(-10, 13) --> Q2

(2.5, -5.5) --> Q4

(9, -10) --> Q4

(-12, 3.4) --> Q2

(-5/8, 5) --> Q2

(-6.4, -6.3) --> Q3

Cheers.

Find the derivative of <br> y = 1/ (3x^3) with steps
Ganezh [65]

Answer:

- 9 {x}^{ - 4}

Step-by-step explanation:

y =  \frac{1}{ {3x}^{3} }  =  {3x}^{ - 3}

y =  <  - 3 \times 3 >  {x}^{ - 3 - 1}  \\  =  - 9 {x}^{ - 4}
