What are the coordinates of the midpoint of diagonal LN?
Answer:
4. (-2 1/2, 4 1/2)
Step-by-step explanation:
Midpoint Formula is (x1+x2)/2, (y1+y2)/2
So (-6+1)/2 , (1+8)/2 = (5)/2, (9)/2 = (2.5,4.5)
And that in fraction form is (-2 1/2, 4 1/2)
Which of the following shows the inverse of {(2, 5), (9, -1), (4, 0), (-3, 8)}? Group of answer choices
What are five steps for solving percentage problems?
Answer:
Find the percentage of the original or real number.
Multiply the final number by 100.
Divide the result of the multiplication by the percentage.
Have a great day
The proportion of the original or true number is then added 100 to the final figure.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
Let's suppose it is required to find the x percentage of y:
First step:
= x% of y
Second step:
= (x/100)y
Third step: Divide x by 100
= 0.01xy
Fourth step: Multiply the remaining term(0.01x and y).
= 0.01xy
The fifth step: Round off if required
= 0.01xy %
Calculate the proportion of the original or true number.
Add 100 to the final figure.
Subtract the percentage from the multiplication result.
Thus, the proportion of the original or true number is then added 100 to the final figure.

Can someone plz help me on this I’m bad at doing these plz I bed u I beg u plz
Answer:
I'm sorry me dont know kfnkdks
Answer:
A
Step-by-step explanation:
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
A = radius^2 x pi = 1.5^2 x pi = 7 cm^2 (round to the nearest whole number)
total area
48 + 12 + 7 = 67 cm^2
What is the lenghth of a baseball cap 30 kilometers or 30 meters or 30 millimeters or 30 centimeters
Answer:
30 centimeters
Step-by-step explanation:
1. 30 kilometers is way too large for a baseball cap to be measured in. Kilometers are usually used to measure distances between cities.
2. 30 meters is also too large for a baseball cap to be measured in. 30 meters are about 15 basketball players stacked on top of one another.
3. Last and remaining choice is 30 cm. 30 cm is about the same length as a 12 inch ruler.

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.
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=
25
50
Subtract
z=2
z=2
Divide
\text{They scored 2 standard deviations above the mean.}
They scored 2 standard deviations above the mean.
What is the interquartile range (IQR) of the data set represented by this box plot?
Answer:
The IQR (interquartile range) of the data set represented by this box plot is 22 units.
Step-by-step explanation:
Each number of the data set represented as a box plot is something the numbers have individually. The lowest number there (the first number), 38, is called the minimum. The highest number there (the last number), 75, is called the maximum. The second number there, 45, is called the lower quartile. The third number there, 50, is called the median or middle quartile. The fourth number there, 67, is called the higher quartile. In order to find the interquartile range, you need to find the difference between the lower quartile and higher quartile, which means to subtract.
67 (highest quartile) - 45 (lower quartile) = 22 (interquartile range)
Therefore, the IQR (interquartile range) of the data set represented by this box plot is 22 units.
Answer:
It’s 22
Step-by-step explanation:
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?
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.

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]
