You want to find out whether caffeine mitigates the effect of alcohol on reaction time. To study this, you administer to your subjects a drink that is equivalent to three 12-ounce beers, followed by the equivalent of two cups of coffee. Then your subjects complete a simulated driving task in which they must follow a fixed speed limit while driving on a straight road. Wind periodically and randomly pushes the simulated vehicle right, left, or not at all. Speed is measured in miles per hour above or below the 60-mph speed limit, with 1 mph being the smallest unit on the scale. Suppose the first subject scores 9 mph. Determine the real limits of 9. When measuring weight on a scale that is accurate to the nearest 0.2 pound, what are the real limits for the weight of 120 pounds? When measuring weight on a scale that is accurate to the nearest 0.5 pound, what are the real/limits for the we.ght of 187 pounds?

Answers

Answer 1

Answer:

First Question

lower limit of 9 mph  [tex]j =  8.5 \  mph[/tex]

upper  limit of 9 mph [tex]q =  9.5 \  mph[/tex]

Second Question

lower limit of 120 pounds is  [tex]i =  119.9 \  pounds[/tex]

upper limit of 120 pounds is  [tex]l =  120.1 \  pounds[/tex]

Third  Question

lower limit of 187 pounds is  [tex]a =  186.75 \  pounds[/tex]

upper limit of 187 pounds is  [tex]b =  187.25 \  pounds[/tex]  

Step-by-step explanation:

From the question we are told that

  The amount of beer administered is  three 12-ounce beers

  The  amount of coffee administered is  two cups of coffee

  The  speed limit is   60-mph

  The smallest unit of scale is  1 mph

  The first subject scores 9 mph

Generally given that the smallest unit of scale is  1 mph then the deviation of  9 mph will be by [tex]\frac{1}{2} \ mph[/tex]

Hence the lower limit of 9 mph is

    [tex]j =  9 - 0.5[/tex]

    [tex]j =  8.5 \  mph[/tex]

And  the upper  limit of 9 mph is

    [tex]q =  9 + 0.5[/tex]

    [tex]q =  9.5 \  mph[/tex]    

Generally given that the measuring weight on a scale that is accurate to the nearest 0.2 pound then 120 pounds will deviate by  [tex]\frac{1}{0.2} \ pounds[/tex]

Hence the lower limit of 120 pounds is

    [tex]i =  120 - 0.1[/tex]

    [tex]i =  119.9 \  pounds[/tex]

And  the upper  limit of 120 pounds is

    [tex]l =  120 + 0.1 [/tex]

    [tex]l =  120.1 \  pounds[/tex]    

Generally given that the measuring weight on a scale that is accurate to the nearest 0.5 pound then  187 pounds will deviate by  [tex]\frac{1}{0.5} \ pounds = 0.25 \ pounds  [/tex]

Hence the lower limit of 120 pounds is

    [tex]a =  187 - 0.25[/tex]

    [tex]a =  186.75 \  pounds[/tex]

And  the upper  limit of 120 pounds is

    [tex]b =  187 + 0.25 [/tex]

    [tex]b =  187.25 \  pounds[/tex]      

Answer 2

Caffeine migrates the effects of alcohol.

Caffeine being a drug in itself is able to remove the effects of alcohol drugs. In order to study the effects of drinking coffee can be used to cure and treat the patients suffering.

Thus caffeine has more medicinal usage.

The study administered to the subject that drink coffee equivalent to three 12 ounces of beer was taken in 2 cups of coffee. The subjects were asked to do driving takes which has some mixed reactions.The goal was to find a cause-and-effect relationship. The study proves that the caffeine kept them more awake as per the use of alcohol of the beer.Hence as per the effect of chemicals, the effects of weights increased. Thus was able to migrate the reaction time.

Step-by-step explanation:

Any scientific or graphing calculator can evaluate this expression for you.

__

When adding numbers in scientific notation, they need to have the same multiplier exponent. Here, it is convenient to use 10^6:

  8.0×10^5 = 0.8×10^6

  6.0×10^7 = 60×10^6

Then the sum is ...

  (0.8 +60)×10^6 = 60.8×10^6 = 60,800,000

Show how to solve the following; answer must be with fractions and pi
theta=tan^-1(-6/6)
I can get the decimal form from calculator, but I require the fractional answer and I need to know how it even gets obtained. How do we know what inverse tan of -6/6 will = to?

Answers

Answer:

3pi/4 and -pi/4

Step-by-step explanation:

We can simplify -6/6 to -1.

Therefore, this function can be simplified to arctan(-1).

Recall that the meaning of arctan is to find a value that will get the value inside the parenthesis when taken the tangent of it. In other words, tan(x) = -1.

Recall that tan(x) = sin(x)/cos(x). Now recall that sin(pi/4) and cos(pi/4) are both sqrt(2)/2, meaning that tan(pi/4) is 1. To make it -1, we can either make sin(x) -1 while keeping cos(x) 1, or the other way around.

If x is -pi/4, cos(x) will still be 1, but sin(x) will be -1, so tan(-pi/4) will be -1.

If x is 3pi/4, cos(x) will be -1, but sin(x) will still be 1, so tan(3pi/4) will be -1.

Side note: there are still infinite more answers. You can attain them by adding or subtracting 2pi as many times as you want from 3pi/4 or -pi/4 and still get an arctan of -1.

. A 0.660 kg ball is dropped from rest from the top of a building and falls for
5.65 seconds. How tall was the building? [Neglect friction. Assume on or near
the Earth's surface.]

Answers

Answer:

The height of the building is 156.42 m

Step-by-step explanation:

Given;

mass of the ball, m = 0.66 kg

time of fall, t = 5.65 s

initial velocity of the ball, u = 0

Apply the following kinematic equation to determine the height of the building;

h = ut + ¹/₂gt²

h = ¹/₂gt²

h = ¹/₂ x 9.8 x 5.65²

h = 156.42 m

Therefore, the height of the building is 156.42 m

The building was 156.42 metres tall

From the question we are told that

the mass of the ball, m = 0.66 kg

the time of fall, t = 5.65 s

the initial velocity of the ball, u = 0

If we use one of the equations of motions in

h = ut + ¹/₂gt², we then have

h = (0 * t) +  (0.5 * 9.8 * 5.65²)  

h = 4.9 * 31.923  

h = 156.42 m

The height of the building is 156.42 m

Find the value of x - The answer is 45, but I need to show my work!!!

THANK YOU

Answers

Answer:

x = 45°

Step-by-step explanation:

The total measurement is 360° (the measurement of a circle).

Set the equation. Set all measurements equal to 360:

228 + (x + 29) + (x + 13) = 360

Combine like terms:

228 + 29 + 13 + 2x = 360

2x + 270 = 360

Isolate the variable, x. Note the equal sign, what you do to one side, you do to other. Do the opposite of PEMDAS. First, subtract 270 from both sides:

2x + 270 (-270) = 360 (-270)

2x = 360 - 270

2x = 90

Next, divide 2 from both sides of the equation:

(2x)/2 = (90)/2

x = 90/2

x = 45

x = 45° is your answer.

Okay I think these are the answers for the Static blurs in the passage the principal reads

Good morning students, teachers, and staff! The teachers have joined the school fundraiser. They will be selling books for summer reading. They have a set goal of 360 dollars.

This is 210 dollars more than the 8th graders, but only [tex]\frac{4}{5}[/tex] as much as the 7th graders. For every 60 dollars the teachers plan to raise, the 6th graders plan to raise 50 dollars

The reason why the teachers goal is $360 is because on page 12 on the graphs it says that the teachers goal is $360, now thats big brain thinking

The teachers goal is 210 dollars more than the 8th graders because 360 - 150 = 210. It is also [tex]\frac{4}{5}[/tex] of the 7th graders goal because 6th graders plan to raise 50 dollars because $60*6=360 and $50*6 is $300. 6 is the common multiple of of 50 and 60

50, 100, 150, 200, 250, 300

60, 120, 180, 240, 300, 360

Boom.

For B you can say

1. The 6th grades' goal is more than the 8th graders goal

2. The 7th grades' goal is more than the 6th and 8th

3. The 8th grades' goal is [tex]\frac{1}{2}[/tex] of the 6th grades' goal

C I think the teachers goal is 360

I hope this helps you! I'm sorry it took long but it is worth it when helping others.
