Answers

Answer 1

A controlled experiment is a scientific test conducted under controlled conditions. That is, change only one (or a few) factors at a time and keep all others constant.

Control Experiment:

Controls eliminate alternative explanations for experimental results, particularly experimental error and experimenter bias. Many controls, like molecular markers used in SDS-PAGE experiments, are specific to the type of experiment being performed and may simply have the purpose of confirming that the instrument is functioning properly. I have. Choosing and using appropriate controls and ensuring that experimental results are valid (eg, no confounding variables) can be very difficult. Control measurements can also be used for other purposes. For example, measuring the background noise of a microphone in the absence of a signal allows the noise to be subtracted from later signal measurements to produce a higher quality processed signal.

For example, if a researcher fed a laboratory artificial sweetener to 60 laboratory rats and observed that 10 of them subsequently became ill, the underlying cause could be the sweetener itself or could be something else. Other variables that may not be immediately apparent can interfere with experimental design. For example, an artificial sweetener can be mixed with a diluent, and it could be the diluent that causes the effect.To see the effect of the diluent, he does the same test twice. A diluent with artificial sweeteners and a diluent-only version in the same way. Here the experiment is checked for diluent and the experimenter can distinguish between sweetener, diluent and no treatment. Controls are usually required when confounding factors cannot be easily separated from the primary treatment. For example, a tractor may need to be used to spread manure when there is no other practical way to spread it. The simplest solution is for the tractor to drive over the plot without spreading fertilizer and control the effects of tractor traffic.

The simplest types of controls are negative and positive controls, both of which are found in many different types of experiments. If both are successful, these two controls usually have the most latency. sufficient to eliminate significant confounding variables. That is, an experiment produces a negative result when a negative result is expected and a positive result when a positive result is expected.

a) Work out the total distance travelled on the cycle.
b) Work out the acceleration in the last 8 seconds.

Answers

The total distance travelled on the cycle is 30.46m and the acceleration  is the last 8 seconds is 0.85 m/s².

What is acceleration?

"Acceleration is the measure of the speed at which velocity changes."

OR "Acceleration depends upon the velocity if the velocity continously increases or decreases the acceleration will be produced."

Positive acceleration results from continuously increasing velocity.

Negative acceleration will be negative if the velocity is continuously decreasing.

FORMULA

Acceleration is defined as a change in velocity divided by time, or a = (Vf-Vi)/t UNIT.

Meter/second+square, or m/S², is the SI unit of velocity in the MKS system.

a. Total distance = Hypotenuse₁ + mid distance + Hypotenuse₂

Hypotenuse₁ = [tex]$ \sqrt{10^2 + 6^2} $[/tex]

Hypotenuse₁ = 11.66m

mid distance = 12 - 6

                      = 6m

Hypotenuse₂ = [tex]$ \sqrt{10^2 + (20-12)^2} $[/tex]

Hypotenuse₂ = [tex]$ \sqrt{10^2 + (8)^2} $[/tex]

Hypotenuse₂ = 12.80m

Total distance = 11.66m + 6m + 12.80m

Total distance = 30.46m

b. Acceleration  [tex]{\displaystyle ={\frac { \text{v - u} }{t}}[/tex]

[tex]\displaystyle = {\frac { \text{12.80 - 6} }{8}[/tex]

[tex]\displaystyle = {\frac { 6.80 }{8}[/tex]

0.85 m/s²

Thus, the total distance travelled on the cycle is 30.46m and the acceleration  is the last 8 seconds is 0.85 m/s².

jon gets to work in 20 min when he drives his car. riding his bike (by the same route) takes him 45 min. his average driving speed is 14.5 mph greater than his average speed on the bike. how far does he travel to work?

Answers

The distance Jon travels to work is 472.5 miles.

Let d be the distance Jon travels to work.

The time it takes to drive is 20 minutes and the time it takes to bike is 45 minutes.

The difference in speed between driving and biking is 14.5 mph.

We can set up the following equation:

20min * (14.5mph + x) = 45min * x

Solving for x gives us the average speed of Jon on the bike, which is 10.5 mph.

Now we can use the distance formula to solve for d:

d = rate * time

d = 10.5mph * 45min

d = 472.5 miles

Therefore, the distance Jon travels to work is 472.5 miles.

Given the following P(A) = 0.3, P(B) = 0.2, P(A) and P(B) 0.06. So, A and B are independent. This can be solved using probability concept.

What is probability?

The word "probability" derives from the Latin word "probitatem," which means "credibility, likelihood," from the noun probabilis in the 14th century (see probable). The phrase was first used in a mathematical meaning in 1718.

A probability is a number that expresses the possibility or likelihood that a specific event will take place. Probabilities can be stated as proportions with a range of 0 to 1, or as percentages with a range of 0% to 100%.

Given that,

P(A) = 0.3

P(B) = 0.2

P(A and B) = 0.06

Now, P(A and B) = P(A) × P(B)

find the area of the part of the plane 5x + 3y + z = 15 that lies in the first octant.

Answers

The area of the part of the plane 5x + 3y + z = 15 that lies in the first octant is 15x^3/6 + 45x^2y/2.

What is area?

Area is a measure of the size of a surface or the amount of space it takes up. It can be measured in square units such as square feet, square meters, or acres. Area is used to describe the size of a two-dimensional object or shape, and is often used when discussing the size of a plot of land, a room, or other geographical area.

The first octant is defined as the area in the three-dimensional Cartesian coordinate system where all the coordinates are positive. In this case, the equation 5x + 3y + z = 15 can be rearranged to solve for z: z = 15 - 5x - 3y. This new equation can then be used to find the area of the plane that lies in the first octant by integrating the equation over the area of the octant.

To solve for the area, we must first find the boundaries of the octant. Since all coordinates must be positive, the boundaries of the octant are x = 0, y = 0, and z = 0. The area of the plane that lies in the first octant is then computed using the triple integral:

Area = ∫∫∫ 0 0 0 15-5x-3y dzdydx

= ∫∫ 0 0 (15x + 45y)dydx

= ∫ 0 (15x^2/2 + 45xy)dx

= 15x^3/6 + 45x^2y/2

Therefore, the area of the part of the plane 5x + 3y + z = 15 that lies in the first octant is 15x^3/6 + 45x^2y/2.

Answers

The equation of the line that passes through the points (-6,4) and (-2,2) is y - 4 = -1/2(x + 6)

What is the equation of the line?

To find the equation of a line that passes through two given points, we can use the point-slope form of the equation of a line, which is:

y - y1 = m(x - x1)

Where (x1, y1) is a point on the line, and m is the slope of the line.

The slope of the line can be found by using the two points:

m = (y2 - y1) / (x2 - x1)

So,

m = (2 - 4) / (-2 - (-6)) = -2/4 = -1/2

We know that the line passes through the point (-6,4) so we can substitute the values into the equation:

y - 4 = -1/2(x + 6)

Hence, the equation of the line that passes through the points (-6,4) and (-2,2) is y - 4 = -1/2(x + 6)

Assume that the linear function f(x) contains the points f(1) = 5 and f(9) = 37. What is the value of f(f(6))?

Answers

Answer:

101

Step-by-step explanation:

f(1) = 5 = 4*1 +1

f(9) = 37 = 4*9+1

f(6) = 4*6+1 = 25

f(f(6)) = f(25) = 4*25+1 =101

Answer:

  101

Step-by-step explanation:

Given the values of a linear function f(1) = 5 and f(9) = 37, you want the value of f(f(6)).

Linear function

The given ordered pairs are (1, 5) and (9, 37). Using these, we can find the slope of the function to be ...

  m = (y2 -y1)/(x2 -x1)

  m = (37 -5)/(9 -1) = 32/8 = 4

The y-intercept is ...

  b = y -mx

  b = 5 -4(1) = 1

So the function in slope-intercept form is ...

  y = mx +b

  f(x) = 4x +1

Application

The value of f(6) is ...

  f(6) = 4·6 +1 = 25

The value of f(f(6)) is ...

  f(f(6)) = f(25) = 4·25 +1 = 101

The value of f(f(6)) is 101.

Find the area of the region enclosed by the inner loop of the curve.r = 6 + 12 sin θ

Answers

The area of the region enclosed by the inner loop of the curve can be calculated by integrating the function r = 6 + 12 sin θ over the interval of θ.

The area of the inner loop is given by Area = 1/2 ∫r^2 dθ = 1/2 ∫(6 + 12 sin θ)^2 dθ

We can solve this integral by breaking it into two parts: Area = 1/2 (∫(6 + 12 sin θ)^2 dθ) = 1/2(∫36 + 72sin θ + 144sin^2 θ dθ)

The first integral is simple and equals to 36*θ and the second one is equal to 48θ - 48cos(2θ)

The limits of integration are [0, 2π]

So the area of the inner loop is 1/2(36*2π + 48(2π) - 48(2)) = 72π

So the area of the region enclosed by the inner loop of the curve is 72π square units.

This frequency distribution represents the commission earned (in dollars) by salespeople employed at several branches of a large chain store. Find the mean and modal class for the data

Answers

For the given data the mean is 180.28 and the modal class is 177 - 185.

First finding mean:

For the class of 150 - 158, the class boundaries are 149.5 - 158.5.

Middle value = (150 + 158)/2 = 154

Frequency = 5

mean= 154 × 5 = 770

For the class 159 - 167, the class boundaries are 158.5 - 167.5

Middle value  = (159 + 167)/2 = 163

Frequency = 16

middle value.  frequency = 163 × 16 = 2608

For the class 168 - 176, the class boundaries are 167.5 - 176.5

Middle value = (168 + 176)/2 = 172

Frequency = 20

middle value.  frequency = 172 × 20 = 3440

For the class 177 - 185, the class boundaries are 176.5 - 185.

Middle value = (177 + 185)/2 = 181

Frequency = 21

middle value.  frequency  = 181 × 21 = 3801

For the class 186 - 194, the class boundaries are 185.5 - 194.5

Middle value (x_m) = (186 + 194)/2 = 190

Frequency = 20

middle value.  frequency  = 190 × 20 = 3800

For the class 195 - 203, the class boundaries are 194.5 - 203.5

Middle value  = (195 + 203)/2 =199

Frequency = 15

middle value.  frequency  = 199 × 15 = 2985

For the class 204 - 212, the class boundaries are 203.5 - 212.5

Middle value  = (204 + 212)/2=208

Frequency = 3

middle value.  frequency  = 208 × 3 = 624

Now in order to determine the mean of this group data all values calculated separately through the product of middle value and frequency will be added together and divided by the total frequency count (i.e 100).

That is

Mean =  ( 770 + 2608 + 3440 + 3801 + 3800 + 2985 + 624 ) = 18028 / 100

Mean  =   180.28

Now determine the model class:

Model class refers to the with the highest occurring frequency. So this is the class "177 - 183" having the frequency 21.

Answers

The interval should be 12 hours and 25 minutes for the two high tides and two low tides.

What is interval ?

An interval refers to the amount of time it takes for a tide to go from high to low or low to high

The reason for two high tides and two low tides each day is due to the gravitational pull of the moon and the sun on Earth's oceans. These gravitational forces cause the water in the oceans to bulge, creating high tides. The gravitational pull of the moon is stronger than that of the sun, so the moon has a greater impact on tides.

The time it takes for the tide to go from high to low and back to high is called the tidal period, which is about 12 hours and 25 minutes. This is not exactly 24 hours because the Earth is also rotating on its axis, so the position of the Moon and the Sun relative to a specific location on the Earth's surface is constantly changing.

So, the interval should be 12 hours and 25 minutes for the two high tides and two low tides.

suppose that motorola uses the normal distribution to determine the probability of defects and the number of defects in a particular production process. assume that the production process manufactures items with a mean weight of 10 ounces. calculate the probability of a defect and the suspected number of defects for a 1,000-unit production run in the following situations. (a) the process standard deviation is 0.18, and the process control is set at plus or minus one standard deviation. units with weights less than 9.82 or greater than 10.18 ounces will be classified as defects. if required, round your answer for the probability of a defect to four decimal places and for the number of defects to the nearest whole number. probability of a defect: number of defects: (b) through process design improvements, the process standard deviation can be reduced to 0.06. assume that the process control remains the same, with weights less than 9.82 or greater than 10.18 ounces being classified as defects. if required, round your answer for the probability of a defect to four decimal places and for the number of defects to the nearest whole number. probability of a defect: number of defects: (c) what is the advantage of reducing process variation, thereby causing process control limits to be at a greater number of standard deviations from the mean? reducing the process standard deviation causes a - select your answer - in the number of defects.

Answers

P( X < 9.85 or X > 10.15 ) ≈ 0.3171 up to four decimal places.

P( X < 9.85 or X > 10.15 ) ≈ 0.0027 up to four decimal places.

Probability

The simple definition of probability is the likelihood that something will occur. We can discuss the probabilities of different outcomes, or how likely they are if we are unclear about how an event will turn out. Statistics refers to the study of occurrences subject to probability.

According to the question

a) Assuming that X is the random variable that takes the place of the number of defectives and has a normal distribution with a mean of 10 ounces and a standard deviation (σ) of 0.15.

The random variable's values deviate from the mean by 1, causing them to either exceed or fall short of (10 + 0.15) and (10-0.15)

= 10.15 or 9.85.

The following formula may be used to determine the likelihood that there will be either more or lesser defects than the range of 10.15 to 9.85:

P( X < 9.85 or X > 10.15 ) = 1 - P[tex](\frac{9.85-10}{0.15} < \frac{X - 10}{0.15} < \frac{10.15-10}{0.15} )[/tex]

P( X < 9.85 or X > 10.15 ) = 1 - φ(1) - φ(-1)

Now we calculate the value of z for z = 1 and z = -1; we have: 0.841345 and 0.158655 respectively

P( X < 9.85 or X > 10.15 ) = 1 - (0.841345 - 0.158655)

P( X < 9.85 or X > 10.15 ) = 0.31713

P( X < 9.85 or X > 10.15 ) ≈ 0.3171 up to four decimal places.

b) It is possible to lower the process standard deviation to 0.05 by making modifications to the process design.

The following formula may be used to determine the likelihood that the number of defectives is either larger than 10.15 or lesser than 9.85:

P( X < 9.85 or X > 10.15 ) = 1 - P[tex](\frac{9.85-10}{0.15} < \frac{X - 10}{0.15} < \frac{10.15-10}{0.15} )[/tex]

P( X < 9.85 or X > 10.15 ) = 1 - φ(3) - φ(-3)

Now we calculate the value of z for z = 3 and z = -3; we have: 0.99865 and 0.00135 respectively

P( X < 9.85 or X > 10.15 ) = 1 - (0.99865 - 0.00135)

P( X < 9.85 or X > 10.15 ) = 0.00271

P( X < 9.85 or X > 10.15 ) ≈ 0.0027 up to four decimal places.

(c) What is the benefit of increasing the number of standard deviations from the mean for process control limits by minimizing process variation?

As we can see from the reduction from a to b above, the key benefit of minimizing process variance is that it will decrease the likelihood of receiving a defective item.

Solve the puzzle from the clues one of is 3 when you pair me with 36 our LCM is 36 I am greater the 6 but less than 12 what is the mystery number


HELPPP PLSSS

Answers

Answer:

Step-by-step explanation:

The mystery number is 9. The least common multiple of 3 and 36 is 36. When you pair 9 with 36, their least common multiple is still 36. 9 is greater than 6, but less than 12. Therefore, the mystery number is 9.

A triangle has two sides of length 14 and 6. What is the smallest possible whole-number length for the third side?

Answers

The smallest possible whole-number length for the third side is 12

How to determine the value

Following the Pythagorean theorem which states that the hypotenuse square is equal to the sum of the squares of the other two sides in a triangle.

This is represented as;

a² = b² + c²

Given that;

a is the hypotenuse sideb is the opposite sidec is the adjacent side of the triangle

From the information given, we have that;

14² = 6² + c²

Find the square values

196 = 36 + c²

collect like terms

c² = 196 - 36

subtract the values

c² = 160

Find the square root of both sides

c = √160

c = 12. 65

Thus, the value is 12
