g About 52% of American adults live in middle-income households. Suppose a sample of 20 American adults is selected. Let X be the number of adults from the sample that live in middle-income households. What is the probability distribution of X
Answer:
P (x= 0) = 0.00384
P (x= 1) = 0.000009133
P (x= 2) = 0.00009399
P (x= 3) = 0.0061
P (x= 4) = 0.00281
P (x= 5) = 0.00975
P (x= 6) = 0.0264
P (x= 7) = 0.05772
P (x= 8) = 0.0202
P (x= 9) = 0.14550
P (x= 10) = 0.1733
P (x= 11) = 0.17077
P (x= 12) = 0.138751
P (x= 13) = 0.0925
P (x= 14) = 0.0501
P (x= 15) = 0.0217
P (x= 16) = 0.00735
P (x= 17) = 0.00187
P (x= 18) = 0.000259
P (x= 19) = 2 0.0000385
P (x= 20) =0.000000208
Step-by-step explanation:
This is a binomila probability distribution as the success and failure are same and number of trials is fixed.
Here p =0.52 and q= 1-0.52= 0.48
n= 20 Now the probability distribution of X = 0,1,2,--------20
Applying the binomial distribution we can find the probability distribution of X taking the different values as
P (x= 0) = 20c0 (0.52)^0 (0.48)^20= 0.00384
P (x= 1) = 20c1 (0.52)^1 (0.48)^19= 0.000009133
P (x= 2) = 20c2 (0.52)^2 (0.48)^18= 0.00009399
P (x= 3) = 20c3 (0.52)^3 (0.48)^17= 0.0061
P (x= 4) = 20c4 (0.52)^4 (0.48)^16= 0.00281
P (x= 5) = 20c5 (0.52)^5 (0.48)^15= 0.00975
P (x= 6) = 20c6 (0.52)^6 (0.48)^14= 0.0264
P (x= 7) = 20c7 (0.52)^7 (0.48)^13= 0.05772
P (x= 8) = 20c8 (0.52)^8 (0.48)^12= 0.0202
P (x= 9) = 20c9 (0.52)^9 (0.48)^11= 0.14550
P (x= 10) = 20c10 (0.52)^10 (0.48)^10= 0.1733
P (x= 11) = 20c11 (0.52)^11 (0.48)^9= 0.17077
P (x= 12) = 20c12 (0.52)^12 (0.48)^8= 0.138751
P (x= 13) = 20c13 (0.52)^13 (0.48)^7= 0.0925
P (x= 14) = 20c14 (0.52)^14 (0.48)^6= 0.0501
P (x= 15) = 20c15 (0.52)^15 (0.48)^5= 0.0217
P (x= 16) = 20c16 (0.52)^16 (0.48)^4= 0.00735
P (x= 17) = 20c17 (0.52)^17 (0.48)^3= 0.00187
P (x= 18) = 20c18 (0.52)^18 (0.48)^2= 0.000259
P (x= 19) = 20c19 (0.52)^19 (0.48)^1= 0.0000385
P (x= 20) = 20c20 (0.52)^20 (0.48)^0= 0.000000208

The science club is going on a field trip to the science museum. The club has at most $800 to spend on the trip. The bus for the trip costs $100, and meals at the museum cost $4.50 per student. If admission to the museum is $12 per student and $16 per adult, and there are six chaperones attending, how many students can go on the trip? Write inequality to represent the situation. do not solve the inequality. Defined the variable.
Answer:
38 students
Step-by-step explanation:
100+(16x6)=196
800-196=631
4.50+12=16.5
63/116.5=38.24
Answer:
100+4.50(s)+12(s)+96 less than or equal to 800
[tex] \leqslant [/tex]
s=students
Step-by-step explanation:
they can spend up to 800 dollars OR LESS. They have a charge of 100 dollars for the bus, plus a charge of 4.50 per student for lunches, plus a charge of 12 dollars per student for admissions plus 16 dollars times 6 (96) for the chaperones. All of this gives us our inequality above.
I really hope this helps!
PS: the reason why the adults don't get their own variable is because it says to define the variable not variable(s). You also cannot group the adults with the students because the student costs and the adult costs are two totally seperate and different amounts. if you just used variable p for people it wouldn't work because you wouldn't know how many adults were required to pay adult admission.

Ileana drew a marble at random from a bag containing 4 blue 3 red 2 yellow and 5 green marbles. What is the probability that she picked a marble that was not red?
Answer:
=11/14
Step-by-step explanation:
Step-by-step explanation:
Number of blue marbles n(blue)=4
Number of red marbles n(red)=3
number of yellow marbles n(yellow)= 2
number of green marbles n(green)=5
total number of marbles n(S)=4+3+2+5=14
P(red)=n(red)/n(S)
P(red)=3/14
We have to determine the probability that the card picked is not red which means the card can be blue or yellow or green.
P(not red)=1-P(red)
=1-3/14
=11/14
Answer:
11/14
Step-by-step explanation:
These are all the marbles that are there:
4 blue
3 red
2 yellow
5 green
If you want to figure out the probability of a marble not being red, you can either find the probability that the marble is blue, yellow, or green or you could subtract the probability that the marble is red from 1 (same thing either way)
There are 14 marbles and 11 of them are not red, so the the probability that a marble drawn will not be red is 11/14.

A tank contains 1000 L of brine (salt water) with 15 kg of dissolved salt. Pure water enters the tank at a rate of 10 L/min. The solution is kept throughly mixed and drains from the tank at the same rate. How much salt is in the tank after t minutes
Answer:
[tex]y=15e^{e^{- \frac{t}{100}}}kg[/tex]
Step-by-step explanation:
Let y(t) represent the amount of salt in the tank after t minutes. Therefore:
[tex]\frac{dy}{dt}=rate\ in-rate\ out[/tex]
Pure water is entering at a rate of 10 L/min, therefore rate in = 0
The tank contains 1000 L of brine (salt water) with 15 kg of dissolved salt, and a mixed solution leaving at 10 L/min hence;
[tex]rate\ out = \frac{y(t)\ kg}{1000\ L}*10\ L/min= \frac{y(t)\ kg}{100\ min}\\\\Therefore:\\\\\frac{dy}{dt}=0- \frac{y(t)}{100} \\\\\frac{dy}{dt}=- \frac{y(t)}{100}\\\\\frac{dy}{y}=- \frac{1}{100}dt\\\\\int\limits{\frac{dy}{y}} =\int\limits- \frac{1}{100}dt\\\\lny=- \frac{t}{100}+C\\\\Taking\ exponetial\ of\ both\ sides:\\\\y=e^{- \frac{t}{100}+C}\\\\y=e^C.e^{- \frac{t}{100}}\\\\y=Ae^{- \frac{t}{100}}(A=e^C)\\\\at\ y=15kg, t=0\\\\15=Ae^{e^{- \frac{0}{100}}}\\\\A=15\\\\[/tex]
[tex]y=15e^{e^{- \frac{t}{100}}}kg[/tex]

Charlotte and Barry are each assigned a paper for a class they share. Charlotte decides to write 12 pages at a time while Barry decides to write 2 pages at a time. If they end up writing the same number of pages, what is the smallest number of pages that the papers could have had?
Answer:
12 ( or 24, depending on what the question is asking)
Step-by-step explanation:
The lowest common multiple of 12 and 2 is 12.
If Charlotte doesn't write anymore pages after writing the original twelve, and Barry writes 2 pages six times, they both write the same number of pages. So, the smallest number of pages is 12
However, if the question is asking for the smallest total number of pages, then the answer is 24 since they both write 12 pages each.
If a loading ramp is placed next to a truck, at a height of 3 feet, and the ramp is 17 feet long, what angle does the ramp make with the ground
Answer:
10.16°
Step-by-step explanation:
To solve for this question, we use Sine rule
Sin θ = Opposite/Hypotenuse
θ =??
Opposite = Height of the truck = 3 feet
Hypotenuse = length of the ramp = 17 feet
Hence
Sin θ = 3/17
Sin θ = 0.1764705882
θ = arcsin(0.1764705882)
θ = 10.16424862°
Approximately
10.16°
The angle the ramp makes with the ground is 10.16°
The angle that the ramp makes with the ground is 10.2 degrees
The set-up will give a right triangle.
Given the following parameters:
Length of the ramp = 17feet (hypotenuse)Height of the truck = 3feet (opposite)To get the angle of elevation, we will use the SOH CAH TOA identity as shown:
Sin theta = opp/hyp
Sin theta = 3/17
theta = arcsin(3/17)
theta = 10.2 degrees
Hence the angle that the ramp makes with the ground is 10.2 degrees

1) Alexa Corp acquired several assets from Bonsai Corp. for $4,200,000. Assets acquired included a building, a stamping machine, and a forklift. An appraisal of the assets valued the building at $2,400,000, the press at $1,000,000, and the conveyor belt at $600,000. What is the value that will be assigned to each of these assets?
Answer:
Value assigned for Building = $2,520,000
Value assigned for Press = $1,050,000
Value assigned for Conveyor belt = $630,000
Step-by-step explanation:
Total appraisal value = Building + Press + Conveyor belt
Total appraisal value = 2,400,000 + 1,000,000 + 600,000
Total appraisal value = $4,000,000
Value assigned for Building = (2,400,000/4,000,000)*4,200,000
Value assigned for Building = $2,520,000
Value assigned for Press = (1,000,000/4,000,000)*4,200,000
Value assigned for Press = $1,050,000
Value assigned for Conveyor belt = (600,000/4,000,000)*4,200,000
Value assigned for Conveyor belt = $630,000
The weights of cockroaches follow a Normal distribution with mean 80 grams and standard deviation 2 grams. Use normal table to answer the question below:
What percent of cockroaches weigh greater than 85 grams?
Answer:
0.621%
Step-by-step explanation:
First of all let's find the z-score which is given by the formula;
z = (x' - μ)/σ
We are given;
Mean; μ = 80 g
Standard deviation; σ = 2 g
Test score; x' = 85 g
Thus;
z = (85 - 80)/2
z = 5/2
z = 2.5
From the z-distribution table attached, at z = 2.5, the probability is:
P(z > 2.5) = 1 - 0.99379 = 0.00621 or 0.621%

Find the number of CD's which must be produced to break even.
The number of CD's which must be produced to break even is no
Answer:
Kindly check explanation
Step-by-step explanation:
Given that:
Variable cost = $20
Fixed cost = $30000
selling price = $49
Number of CD's produced = x
Cost (C) as a function of number of CD's produced :
Fixed cost + (variable cost * Number produced)
C = $30000 + ($20 * x)
C = $30000 + 20x
Revenue :
Selling price per CD * number of CDs produced
$49 * x
R = 49x
PROFIT:
REVENUE - COST
$30000 + 20x - 49x
30000 - 29x
Number of CD's which must be produced to break even:
Break even quantity = Fixed costs / (Sales price per unit – Variable cost per unit)
Break even quantity = 30000 / (49 - 20)
= 30000 / 29
