Water is pumped from a tank at constant rate, and no more water enters the tank. If the tank contains 19140 L at 4:47 PM and 8097 L at 5:05 PM the same day, how many liters will the tank contain at 5:11 PM that day?
Answers
Answer:
The liters that the tank will contain at 5:11 PM that day are:
4416 Liters.Step-by-step explanation:
Firstly, you must identify the outlet flow of the water pumped from the tank, for this, you must subtract the last volume given from the first volume:
19,140 L - 8,097 L = 11,043 LAnd the minutes that passed from the first volume until the last volume given (18 minutes from 4:47 PM to 5:05 PM), so, you must divide that two values to obtain the outlet flow:
Outlet flow = [tex]\frac{Volume}{Time}[/tex] Outlet flow = [tex]\frac{11,043 L}{18 min}[/tex] Outlet flow = 613.5 [tex]\frac{L}{min}[/tex]Now, you must see the next hour given (5:11 PM), if you see, from 5:05 PM to 5:11 PM has passed 6 minutes, taking into account this, you replace the equation of outlet flow to clear the volume:
Outlet flow = [tex]\frac{Volume}{Time}[/tex] Volume = Outlet flow * timeAnd replace the values to obtain the new volume pumped:
Volume = 613.5 [tex]\frac{L}{min}[/tex] * 6 minVolume = 3681 L.At last, you must subtract these liters from the last volume identified in the tank:
New Volume in the tank = 8097 L - 3681 LNew Volume in the tank = 4416 LThe volume in the tank at 5:11 PM is 4416 Liters.
The tank will contain 4416 L of water at 5:11 PM .
Rate of discharge of water:Given that, the tank contains 19140 L at 4:47 PM and 8097 L at 5:05 PM
It means that, in 18 minutes the amount of water discharge is,
[tex]=19140-8097=11043L[/tex]
The rate of flow is,
[tex]=\frac{11043}{18}=613.5L/min[/tex]
From 5:05 PM to 5:11 PM , six minutes are passes.
Water discharge in that six minute is ,
[tex]=613.5*6=3681L[/tex]
The tank will contain at 5:11 PM is,
=[tex]8097-3681=4416L[/tex]

Step-by-step explanation:
For the two points (3, 0) and (-2, 10), the equation of the line can be written using the two-point form.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (10 -0)/(-2 -3)(x -3) +0

The management of a supermarket wants to adopt a new promotional policy of giving a free gift to every
customer who spends more than a certain amount per visit at this supermarket. The expectation of the
management is that after this promotional policy is advertised, the expenditures for all customers at this
supermarket will be normally distributed with a mean of $95 and a standard deviation of $16. If the
management wants to give free gifts to at most 13.57% of the customers, what should the amount be
above which a customer would receive a free gift?
Answers
Answer:
X ≥ 112,6 $
Step-by-step explanation:
Normal Distribution N ( 95 , 16 )
μ₀ = 95
σ = 16
We need to get z (score) for area 0,1357; then from z - Table we get
z (score) = 1,1
Now z (score ) = ( X - μ₀ )/σ
1,1 = ( X - 95 ) / 16
17,60 + 95 = X
X = 112,6 $
That means that in order to get a gift customes has to spend at least 112,6 $

Suppose number of hours employees work in a week at a company are normally distributed with an unknown population mean and a population standard deviation of 2 hours. A random sample of 65 employees weekly hours is taken. These gave a sample mean time of 39 hours. Find the error bound (EBM) of the confidence interval with a 95% confidence level. A 2 by 5 z-table.
Answers
Answer:
0.49
Step-by-step explanation:
We can use the formula to find the error bound:
EBM=(zα/2)(σ/√n)
We know that σ=2 and n=65. We are also given that the confidence level (CL) is 95%, or 0.95. So, we can calculate alpha (α).
α=1−CL
=1−0.95
=0.05
Since α=0.05, we know that α2=0.05/2=0.025. The value of z0.025 is 1.960.
Now we can substitute the values into the formula to find the error bound.
EBM=(zα/2)(σ/√n)
=(1.960)(2/√65)
≈(1.960)(0.248)
≈0.49
So, the error bound (EBM) is 0.49.

Oranges cost 21 cents each.
Alex buys x oranges and Bobbie buys (x+2) oranges.
The total cost of these oranges is $4.20.
Answers
Step-by-step explanation:
x be the number of oranges
x + (x+2) = $4.20
2x + 2 = 4.20
2x = 2.20
x = 1.1
if you wanna check,
1.1 + (1.1 + 2) =$4.20
1.1 + 3.1 =$4.20
4.2 =$4.20
Alex = x = 1.1 oranges
Bobbie = (x+2) = 1.1 + 2 = 3.1 oranges

A product can be made in sizes huge, average and tiny which yield a net unit profit of $14, $10, and$5, respectively. Three centers manufacture these products. The centers respectively have a capacity ofturning out 550, 750, and 275 units of the product per day, no matter what sizes are involved. The manufacturing process necessitates cooling water and each unit of huge, average, and tiny sizesproduced require 22, 16, and 9 gallons of water, respectively. Center 1 has 11,000 gallons of coolingwater available per day, Center 2, 7000, and Center 3, 4000 gallons. The daily demand is of 710, 900,and 350 units of the huge, average, and tiny siz. By company policy, the fraction (scheduled production)(center's capacity) must be the same at all the centers. The company wishes to maximize its profits.
