On a standardized exam, the scores are normally distributed with a mean of 250 and
a standard deviation of 50. Find the 2-score of a person who scored 375 on the exam.
Answers
Answer:
the z-score is within 3
Step-by-step explanation:
first you got to take the standard deviation and add it to the mean since 375 is greater than 250. so the equastion would be
250+50=300+50=350+50=40
so the z-score for the value of 375 is within 3
Answer: 2
Step-by-step explanation:
z=\frac{x-\mu}{\sigma}
z=
σ
x−μ
z-score formula
z=\frac{300-250}{25}
z=
25
300−250
Plug in values
z=\frac{50}{25}
z=

50
Subtract

it's a right triangle, you should know how to find the area for this one :/ I'll give you the formula , you can push the buttons on a calculator ? right? Okay to be fair, I see that there is one extra step, so i'll do that part for you.
Ф=arcSin(8.5/15.7)
Ф = 32.77908067°
15.7*Cos(32.77908067°) = base
13.2 =base
⇒ use this formula ⇒ (1/2)*base*height*depth
just in case base = 13.2
height = 8.5
depth = 6.2
you got it ? right?
10)
we have to solve for the "adjacent side" of the triangle, which will also be the diameter of the cylinder , so
sin(Ф) = 9.5/19.3
Ф= arcSin(9.5/19.3)
Ф= 29.48712567°
19.3*cos(29.48712567°) = Adjacent
16.8 =Adjacent ( diameter of circle)
16.8/2 = radius
8.4 = radius
area of circle = [tex]\pi[/tex][tex]r^{2}[/tex]
area of circle = 221.6707776 [tex]m^{2}[/tex]
volume of a cylinder = area of circle * height
volume of a cylinder = 221.6707776 * 9.5
volume of a cylinder = 2105.872388 [tex]m^{3}[/tex]
11)
we need the formula for an equilateral triangle area
Equilateral Triangle Area = [tex]\sqrt{3}[/tex]/4)* [tex]a^{2}[/tex]
ETA = ([tex]\sqrt{3}[/tex]/4)*[tex]12^{2}[/tex]
ETA = 62.35382907 [tex]mm^{2}[/tex]
Volume Of Prism = length * area
VOP = 17 * 62.35382907
VOP = 1060.015094 [tex]mm^{3}[/tex]

The president of a computer company must decide whether to place the company's new laptop on the market now or wait another year and continue with product testing.
The company's employees inform the president that if he releases the laptop now and no competitive devices enter the market, there will be a profit of $120,409.00; however, if he releases the laptop now and a competitive device enters the market, there will only be a small profit of $29,698.00. The company's employees also inform the president that if he waits another year and no competitive device enters the market, there will be a profit of $84,742.00; however, if he waits another year and a competitive device enters the market, there will be a loss of $59,396.00.
Suppose the company determines that there is a 22% chance that a competitive device will enter the market. What should the president do to maximize the expected profit over the next year?
Answers
Answer:
The president should release the new laptop now
Step-by-step explanation:
The profit if the new laptop is released now and no competitive device enters the market = $120,409.00
The profit if the new laptop is released now and a competitive device enters the market = $29,698
The profit if the new laptop is released in a years time and no competitive device enters the market = $84,742.00
The loss if the new laptop is released in a years time and a competitive device enters the market = $59,396.00
The chance that a competitive device will enter the market = 22%
∴ The chance that a competitive device will not enter the market = 1 - 22% = 78%
The expected increase in profit the company can make, compared to next year, if the new laptop is released and no competitive device enters the market = ($120,409.00 - $84,742.00) × 78% = $27,820.26
The expected increase in profit the company can make, compared to next year, if the new laptop is released and a competitive device enters the market = ($29,698.00 - $59,396.00)×0.22 = ($6,533.56) loss
Therefore, to maximize the expected profit over the next year, the president should release the new laptop now to make an expected profit of $27,820.26 over the next year.

Area of the rectangle
A = base x width = 8 x 6 = 48 cm^2
Area of the triangle
A = (base x height)/2 = (6 x 4)/2 = 12 cm^2
two semicircles are equal to a circle
radius = diameter / 2 = 3/2 = 1.5 cm
