The number of different groups can be found by finding 9C3 (Using combinations)
We will find combinations from n = 9 to r = 3

Therefore, 9C3 = 9!/6!*3! = (9*8*7*6!)/(6!*3*2)
= 3*4*7
= 84 ways.

For part A, The answer is that the car gets better gas mileage. We can see it from the graph that the number of gallons used is on the X axis, and the distance traveled using those number of gallons is on the Y axis. The easiest way to compare would be to look at the 1 gallon of gas. You can see that you can travel 25 miles on 1 gallon of gas. The truck on the other hand will get you 18 miles per gallon. Imagine putting 1 in for X, the Y value would be 18 if you did this. The graph just shows us a visual way of saying the same thing. To determine how much farther the car with a girl on 8 gallons of gas, you would just multiply 8 by 25 for the number of miles traveled by the car. You would multiply 8 by 18 to find the number of miles traveled for the truck. The answers are 200 miles for the car and 144 miles for the truck. 200-144=56 miles farther for the car.

If f(x)=ln(sin(2x)), f''(π/4) is equal to

Licemer1 [7]

Use the chain rule to compute the second derivative:

$f(x)=\ln(\sin(2x))$

The first derivative is

$f'(x)=(\ln(\sin(2x)))'=\dfrac{(\sin(2x))'}{\sin(2x)}=\dfrac{\cos(2x)(2x)'}{\sin(2x)}=\dfrac{2\cos(2x)}{\sin(2x)}$

$f'(x)=2\cot(2x)$

Then the second derivative is

$f''(x)=(2\cot(2x))'=-2\csc^2(2x)(2x)'$

$f''(x)=-4\csc^2(2x)$

Then plug in π/4 for x :

$f''\left(\dfrac\pi4\right)=-4\csc^2\left(\dfrac{2\pi}4\right)=-4$

9. In the figure at right, GH = HI = IJ. Find the length of AK.

marysya [2.9K]

GH = HI = IJ
3( 3.75) = 17.25
so
6.5/AK = 5.75 /17.25
AK = 17.25 * 6.5 / 5.75
AK = 19.5

answer
the length of AK = 19.5

elixir [45]

Answer:

Option C) population

Step-by-step explanation:

We are given the following situation in the question:

A researcher is curious about the average IQ of registered voters in the state of FL.

Sample:

It is a part of a population. It is always smaller than the population.

Statistic:

Any numerical value or any other measure describing a sample of a population is known as statistic.

Population:

It is the universal data set. Every observation belongs to this group which is of interest. Sampling is done within population to obtain small groups of sample.

Parameter:

Any numerical value or any other measure describing the population is known as a parameter.

In this situation, the entire group of registered voters in FL is an example of a population because it contains all the individual for variable of interest.

Variable of interest:

Average IQ of registered voters in the state of FL.

Individual of interest:

Registered voters in the state of FL.
