What's the Following?

Step-by-step explanation:

Answer:

37

Step-by-step explanation:

Highest - lowest = range

64-27= 37

The range of the data set is given by the equation R = 37

The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in.

The range is the set of outputs of a relation or function. In other words, it's the set of possible y values. Recall that ordered pairs are of the form (x,y) so the y coordinate is listed after the x. The output is listed after the input.

Given data ,

Let the data set be represented as Set A

Now , the value of A is

Substituting the values in the equation , we get

A = { 27, 56, 64, 36, 40, 29, 27, 56, 30 }

Arranging the values in set A in the ascending order , we get

A = { 27 , 27 , 29 , 30 , 36 , 40 , 56 , 56 , 64 }

Now , the range of the set = largest value - smallest value

On simplifying the equation , we get

The range R = 64 - 27

The range of set R = 37

Hence , the range is 37

Given :

Two points (7,-4) and (-3,4).

To Find :

The equation of line passes through the given points.

Solution :

We know, equation of line passing through two points (x₁, y₁) and (x₂, y₂) is given by :

[tex]y - y_1 = (\dfrac{y_2-y_1}{x_2-x_1})(x-x_1)\\\\y-(-4) = (\dfrac{4-(-4)}{-3-7})(x-7)\\\\y+4 = -\dfrac{4}{5}(x-7)\\\\5y+ 20 = -4x + 28\\\\5y + 4x = 8[/tex]

Therefore, equation of required line is 5y + 4x = 8.

Answer:

[tex]2y\sqrt{2x}[/tex]

Step-by-step explanation:

For this we have to divide like normally but for the exponents we will subtract them since this is a division problem. We would've added them if we were multiplying.

[tex]\frac{\sqrt{32x^5y^8}}{\sqrt{4x^4y^6}}=\sqrt{8xy^2}[/tex]

Now we will split the 8 into 4 and 2. Also we can take the square root of y² while we're at it.

[tex]y\sqrt{4}\sqrt{2x}[/tex]

Now we take the square root of 4.

[tex]2y\sqrt{2x}[/tex]

Answer:

CASI

Step-by-step explanation:

In Statistics, sampling can be defined as a process used to collect or select data (objects, observations, or individuals) from a larger statistical population using specific procedures.

Sample survey questions are usually read from a computer screen. In a computer-aided personal interview (CAPI), the interviewer reads the questions and enters the responses. In a computer-aided self interview (CASI), the interviewer stands aside and the respondent reads the questions and enters responses. One method almost always shows a higher percent of subjects admitting use of illegal drugs.

This is because they get to interact with a computer rather than a human interviewer.

Answer:

[tex]\%DVD = 14\%[/tex]

Step-by-step explanation:

Given

[tex]Population = 900[/tex]

[tex]Sample = 325[/tex] --- selected adults

[tex]Proportion = 45[/tex] --- those that prefer renting a movie

Required

Represent the proportion as a sample.

This is calculated as thus:

[tex]\%DVD = \frac{Proportion}{Sample} * 100\%[/tex]

[tex]\%DVD = \frac{45}{325} * 100\%[/tex]

[tex]\%DVD = \frac{45 * 100}{325}\%[/tex]

[tex]\%DVD = \frac{45 00}{325}\%[/tex]

[tex]\%DVD = 13.85\%[/tex]

[tex]\%DVD = 14\%[/tex] --- approximated

Answer:

green container

Step-by-step explanation:

Answer: part 1

1. You need a Source of electric power (battery or generator), a load to absorb the power (lamp, motor, heating coil) and wiring to connect the load to the power source!

2. they both give off electricity energy, and they are different because they dont release the same amount of energy

3. Current will increase

Explanation:

In Ohm's law the equation for current is current = voltage / resistance.

In order to explain how current is effected when resistance decreases while voltage stays the same, lets represents the situations with some possible inputs.

Let's compare 3 different closed circuits all with a voltage of 10V.

In circuit 1, the resistance is 5 ohm.

In circuit 2, the resistance is 2 ohms.

In circuit 3, the resistance is 1 ohms.

The current of:

Circuit 1 = Voltage / Resistance = 10 V / 5 ohms = 2 Amps

Circuit 2 = Voltage / Resistance = 10V / 2 ohms = 5 Amps

Circuit 3 = Voltage / Resistance = 10V / 1ohm = 10 Amps

As you can see in this representation, as the resistance in a circuit increases while the voltage is constant, the total current is increased.

4. The resistance of a conductor is the ratio of the voltage

between its ends to the current through it.

If the voltage between the ends of a light bulb's filament

increases but the filament's resistance remains constant,

then the current through it increases by the same factor

as the voltage increase. The effect is to cause the light

to emit more light and heat ... both increase proportional

to the square of the voltage ... and possibly to "burn out".

Part 2

1. it's a circuit wherein all the elements are in parallel and a resistance is fitted in series across which a voltmeter is connected to measure potential drop acrossR so as to find the current across the load that is bulb which connected to in series with the resistor

2. A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses.

3. The switch simply opens (off) or closes (on) the connection between the two terminals on the switch. When the switch is on, current flows along the black wire through the switch to the light, and then returns to ground through the white wire to complete the circuit.

4. the current runs through the motherboard and into the smaller components or the small internal wiring

5. A battery is made up of three parts. The Cathode (positive end +) , the Anode (negative end -) and the electrolyte. The electrolyte allows electrical charges to travel between the cathode and anode. This chemical reactions creates the flow of electricity supplying the electrical voltage potential to power a circuit.

Typical materials of a battery are as follows

- Anode most often is made of zinc

- Manganese dioxide acting as Cathode.

- the electrolyte between and inside contains ions
