You can find the constant of proportionality of the ratio of the price to the number of bouquets from the table by dividing them. For example, it you divide 9 by 3 or 18 by 6, you get 3. Therefore, you know that every bouquet is 3 dollars. :) Hope this helps

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?
Answers
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
Mike drew p pictures. Rick drew 41 fewer pictures than Mike. Choose the expression that shows how many pictures Rick drew.
(A.) p
(B.) 41 + p
(C.) p - 41
(D.) 41 - p
Answers
Answer:
It's p - 41.
Step-by-step explanation:
We're trying to find how many pictures Rick drew, which is 41 less than how many Mike drew, p. To find the expression in situations like these, always take how many fewer was drawn from the amount the other person drew, which would be 41 - p. But this would most likely give us a negative answer, which isn't possible. Switch them around and you have p - 41.
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
Answers
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

What are coordinates?A pair of numbers called coordinates are used to locate a point or a form in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane.
We take two points lying on the line representing the best relationship between variables X and Y.
Points are (1, 9) and (2, 8), so the slope will be (y₂ - y₁)/(x₂ -x₁)
Slope = (9- 8)/(1-2) = -1
Since the slope is negative, the Slope of (-1) shows the negative relationship between X and Y which may be represented by Y = (- X), the equation of a line.
thus It is a negative Association for sure.
A perfect negative correlation has a value of -1.0 and indicates that when X increases by z units, Y decreases by exactly z; and vice-versa. In general, -1.0 to -0.70 suggests a strong negative correlation, -0.50 a moderate negative relationship, and -0.30 a weak correlation.
Therefore, the association between variables X and Y can be best described as Option c.) moderate negative association

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
Answers
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]

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

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?
Answers
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
Answers
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

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?
Answers
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.
