Answer:
p = 0.35
q = 0.65
n = 7
Step-by-step explanation:
To calculate the distribution, we have the following values;
p = 35% = 35/100 = 0.35
q = 1-p = 1-0.35 = 0.65
n = 7
A substantial majority of Americans are cellphone owners across a wide range of demographic groups. By contrast, smartphone ownership exhibits greater variation based on age, household income and educational attainment. Source: Survey conducted Jan. 8 to Feb. 7, 2019. Along with mobile phones, Americans own a range of other information devices.
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.

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.

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.
You make a bet on a horse race. There's a 10% chance of making $300 and a 5% chance of making $500. There's an 85% chance of losing $75. What's the expected value of this bet?

What is 1+1 equal? Oh my I am so rich in points I can just spend my way to having someone answer it for me!
Answer:
x=2
Step-by-step explanation:
1 is = 100%, or 10/10, 1/1, and 1.00
if we have a double of 1, we would double, now 1 and 1=200% 20/10, 2/1, 2.00
turning these franction into whole numbers we will now have
[tex]2\frac{0}{10}[/tex][tex]2\frac{0}{1}[/tex]
so now we have our answer, which is 2
now lets learn 1+1 as pi-

The equation y = 450x represents the number of miles alrplane traveled y ot x hours. The graph below shows the number miles a 5hour flight , after 2 hours which airplane had traveled the farther and by how much ? I need help
Answer:
y = 200x.....the airplane travels 8000 miles in 40 hrs
Step-by-step explanation:
Answer:
Airplane W by 100 miles
Step-by-step explanation:
Airplane Z
y = 450x
Distance travelled after 2 hours
y = 450(2)
y = 900 miles
------------------------
Airplane W
Distance travelled after 2 hours
Reading from the graph
1000 miles
----------------------
after 2 hours which airplane had traveled the farther
Airplane W
and by how much
1000 - 900 = 100

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]

600 students were going on a field trip.
Lunches had to be prepared for them.
Altogether what was the TOTAL number of food and drink items used if each student received:
3 juices
2 pieces of fruit
2 burritos
2 bags of Doritos
1 milk
Answer:
6,000 total items
Step-by-step explanation:
3*600=1800 (total juice)
2*600=1200 (total fruit)
2*600=1200 (total burritos)
2*600=1200 (total doritos)
1*600=600 (total milk)
1800+1200+1200+1200+600=6000
