4) Dan Ariely and colleagues have conducted some extremely interesting studies on cheating (see, for example Mazar, Amir, & Ariely, 2008). To provide an opportunity for cheating, participants are given a packet of problems and told they will be paid $0.50 for each correct answer. The experiment is setup, however, so that the participant doesn’t have to turn in their work, they simply have to state how many problems they solved to get paid. This provides a prime opportunity to cheat to earn extra money. In previous tests where the problems are properly scored, so no cheating, Ariely and colleagues found that scores are normally distributed:  = 3.3,  = 1.0. Here is a list of scores for participants who knew that their work would not be checked. Which of these would you suspect of cheating? Why?

Answer: See explanation

Step-by-step explanation:

Your question isn't complete but let me help out.

You said that you thought of number J, and then subtracted half of it from 34. This can be mathematically written as:

= 34 - (J/2)

Let's reframe the question and assume that you thought of a number J, and then subtracted half of it from 34 and the answer you get is 12. To find J goes thus:

You subtract half of J from 34 and equate it to 12. This will be:

34 - (J/2) = 12

Collect like terms

34 - 12 = J/2

22 = J/2

J = 22 × 2

J = 44

In this scenario, J = 44. We can check to confirm.

Check: 34 - (J/2)

= 34 - (44/2)

= 34 - 22

= 12

Answer:

34 - (J/2)

Step-by-step explanation:

Step-by-step explanation:

y = 3 + 8x^(³/₂), 0 ≤ x ≤ 1

dy/dx = 12√x

Arc length is:

s = ∫ ds

s = ∫₀¹ √(1 + (dy/dx)²) dx

s = ∫₀¹ √(1 + (12√x)²) dx

s = ∫₀¹ √(1 + 144x) dx

If u = 1 + 144x, then du = 144 dx.

s = 1/144 ∫ √u du

s = 1/144 (⅔ u^(³/₂))

s = 1/216 u^(³/₂)

Substitute back:

s = 1/216 (1 + 144x)^(³/₂)

Evaluate between x=0 and x=1.

s = [1/216 (1 + 144)^(³/₂)] − [1/216 (1 + 0)^(³/₂)]

s = 1/216 (145)^(³/₂) − 1/216

s = (145√145 − 1) / 216

Answer: 10

Step-by-step explanation:

First, you need to change 6 and 2/3 into an improper fraction which is 20/3. Then, you need to divide 20/3 by 2/3 to find your answer. To do this, simply turn 2/3 to 3/2 and multiply it by 20/3. 20/3 x 3/2 = 60/6. 60/6 in simplest form is 10. Therefore, you answer is 10.

Answer:

$28.44

Step-by-step explanation:

Time and a half is the normal rate of pay when working overtime at any job and is calculated as 1.5 times the regularly hourly wage of the employee. Therefore we can calculate how much she earns per hour of overtime by doing the following...

$9.48 * 1.5 = $14.22 per hour

Now we can see that Odette earns $14.22 per hour of overtime, since she worked two hours we simply multiply this amount by 2.

$14.22 * 2 = $28.44

Odette Alvarez earned $28.44 for the two hours of overtime.

Step-by-step explanation:

Answer:

  a) no

  b) 143 rectangular containers

  c) 157 cylindrical containers

  d) both (preferring rectangular for the bulk of an order)

Step-by-step explanation:

a) If the company needs to package 6,400 candles, should it use only rectangular or only cylindrical containers to minimize costs?

  No.*

For packaging 41 candles or fewer, the cylindrical container costs less than the rectangular one.

For packaging 6400 candles, there will be 10 candles left over if rectangular containers are used for most of the packaging needs. A dollar can be saved by packaging these remaining candles in a cylindrical container.

__

b) How many rectangular containers will be necessary to package 6,400 candles?

  6400/45 = 142 10/45

If rectangular containers are used for all, then 143 are needed.

__

c) How many cylindrical containers will be necessary to package 6,400 candles?

  6400/41 = 156 4/41

If cylindrical containers are used for all, the 157 are needed.

__

d) Which container should the company use to minimize costs?

  The cost of 143 rectangular containers is 143×$16 = $2288

  The cost of 157 cylindrical containers is 157×$15 = $2355

  The cost of 142 rectangular and 1 cylindrical container is $2287

If only one shape container is used, the company should use rectangular containers to minimize cost. If either shape can be used, cost will be minimized by using one cylindrical container for the remnant of the order.

_____

* This question is directed solely at the cost of materials required for packaging. We have advocated that both rectangular and cylindrical containers be made available. As a practical matter, the cost to the company of maintaining inventory of both sizes of containers may exceed the savings associated with using a cheaper container for smaller orders.

Answer:

Riley made a mistake in step 4.

Step-by-step explanation:

In step 4, Riley applied the division property of equality to divide both sides of the equation by 2. However, the variable is multiplied by -2, not 2. So, the opposite operation Riley should have done is divide both sides of the equation by -2. Therefore, Riley made a mistake in step 4.

Answer:

Increasing

Step-by-step explanation:

Remember that f(x) is the same as y in slope intercept form y = mx + b.

We don’t have a number for “b” which means the line goes across the origin.

Since 5 replaces m, that is the slope and since it’s positive, it is increasing.

Best of Luck!

Answer:

2,144.7

Step-by-step explanation:

The formula for the volume of a sphere is V=4pi r^3/3. Lets apply this formula for your sphere. The radius is 8, so lets plug in 8 in our formula. 4pi 8^3/3. Now, lets solve. 4 times pi. What is pi? We usually think of pi as 3.14. 4x3.14 is 12.56. Now, lets do 8^3/3. 8 times 3 is 512, and divided by 3 is 170.67. Alright, now we have 12.56 times 170.67. That is 2144.7 rounded to the nearest tenth.

Answer:

FIrst number = 35

Second number = 140

Step-by-step explanation:

Sum = 175

Second number = x

First number = 5x - 35

=> x + 5x - 35 = 175

=> 6x - 35 = 175

=> 6x - 35 + 35 = 175 + 35

=> 6x = 210

=> 6x/6 = 210/6

=> x  = 35

Second number = x = 35

First number = 5x - 35 = 5 * (35)  - 35 = 175 - 35 = 140

First number = 140

Second number = 35

Answer:

34 feet

Step-by-step explanation:

From the question, we are told that:

If the room is 30 feet high at the center and 90 feet wide at the floor,

Entire width of the room = 90 feet = 2a

a = 90/2 = 45

Height of the room = b = 30 feet

Foci (c)² = a² - b²

c = √a² - b²

c = √45² - 30²

c = √1125

c = 33.541019662 feet

Approximately to the nearest whole number = 34 feet

Denise and Donna should each stand 34 ft from the outer wall so that they will be positioned at the foci of the ellipse

[tex]\frac{1}{3}[/tex]

Step-by-step explanation:

[tex]\sqrt{\frac{1}{9} } = \sqrt{\frac{1}{3} } {^{2} } \\\\=\frac{1}{3}[/tex]

The square root of the fraction 1/9, would be  ± 1/3.

A perfect square number when taken the square root of it results in an integer.

Numbers that are not perfect squares when taken the square root of it are irrational numbers.

One method of obtaining square roots for perfect squares is prime factorization.

A fraction 1/9 is given,

Now, The square root of this fraction would be √(1/9).

= √1/√9.

= 1/√9.

= 1/3, But it can be both ± 1/3 as both results to 1/9.
