Answer:
When we know the initial population
, the next thing we need to solve the growth constant
to derive the exponential growth function.
If the problem gives the time it takes for the population to double or the doubling time
τ
. We can find the growth constant by substituting the doubling constant into the equation and solving for t.
This means that the statement is TRUE because the term for initial population cancels out when solving for k and the doubling time is given.

Bill has 5 liters of water to pass out to his teammates at the basketball game. If one player drinks 1000 milliliters, two players drink 500 milliliters, and another player drinks 2000 milliliters, how much water does Bill have left at the end of the game?
A. 1,000 liters
B. 2 liters
C. 10,000 liters
D. 1 liter
Answer:
D. 1 liter
Step-by-step explanation:
1000 milliliters = 1 liter
Player 1: 1000 ml or 1 liter
Player 2: 500 ml or .5 liter
Player 3: 500 ml or .5 liter
Player 4: 2000 ml or 2 liter
Add: 1 + .5 +.5 +2 = 4
Subtract: 5 - 4 = 1
Answer: You have 1 liter left

A USA Today poll asked a random sample of
1012 U.S. adults what they do with the milk
in the bowl after they have eaten the cereal
Let be the proportion of people in the
sample who drink the cereal milk A
spokesman for the dairy industry claims that
70% of all US adults drink the cereal milk
Suppose this claim is true.
Find the standard deviation of the sampling
distribution of p
Answer: 0.0188
Step-by-step explanation:
Using the Central Limit Theorem, it is found that the standard deviation of the sampling distribution of p is 0.0144.
Central Limit TheoremBy the Central Limit Theorem, the sampling distribution of sample proportions of a proportion p in a sample of size n has mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1 - p)}{n}}[/tex].In this problem:
Suppose that 70% of all US adults drink the cereal milk, hence [tex]p = 0.7[/tex].A sample of 1012 adults is taken, hence [tex]n = 1012[/tex].Then, the standard deviation is:
[tex]s = \sqrt{\frac{p(1 - p)}{n}} = \sqrt{\frac{0.7(0.3)}{1012}} = 0.0144[/tex]
The standard deviation of the sampling distribution of p is 0.0144.

Is a circle a function?
Step-by-step explanation:
a function that describes a set of points in Cartesian space by mapping each x-coordinate to a y-coordinate, then a circle cannot be described by a function because it fails what is known in High School as the vertical line test. A function, by definition, has a unique output for every input.
Given the median QR and trapezoid MOPN, what is the value of x?

O A. 6
O B. 18
O C. 2
O D. 5
O E. 7
o
F. Cannot be determined
Answer:
D. 5
Step-by-step explanation:
Based on the midsegment theorem of a trapezoid, thus:
QR = ½(OP + MN)
Substitute
27 = ½((5x - 7) + (6x + 6))
27 = ½(5x - 7 + 6x + 6)
Add like terms
27 = ½(11x - 1)
Multiply both sides by 2
2*27 = 11x - 1
54 = 11x - 1
54 + 1 = 11x
55 = 11x
55/11 = x
5 = x
x = 5

Pretzels are given away for free at a local store. The tray is constantly replenished as people take the pretzels.The number of pretzels in the tray is given by the function P(t) = 20 + t^2 − 8cosπt , where t is measured in minutes. When t = 1 minute, find the average rate of change of pretzels in the tray over the next 30 seconds.
Answer:
The answer is "[tex]-13.5 \ / minute \\\\[/tex]"
Step-by-step explanation:
The average rate to the changes of pretzels form [tex]t= 1 \ minutes[/tex] to [tex]t=1.5 \ minutes[/tex] will be:
[tex]=\frac{P(1.5)-p(1)}{1.5-1}\\\\=\frac{(20+(1.5)^2- 8 \cos \pi (1.5))-(20+1^2 -8 \cos \pi)}{0.5}\\\\=\frac{22.25-29}{0.5}\\\\=\frac{-675}{50}\\\\=-13.5 \ / minute \\\\[/tex]
Kyle ordered 7 large pepperoni pizzas from Wild Bill's Pizza, and he used the coupon shown above. If the total bill, after kyle used the coupon, was $82.50, what was the regular price of 1 pizza?
Answer:
Regular price of 1 pizza = $15 {Assuming discount coupon = $22.5}
Step-by-step explanation:
Let regular non discounted price of 7 pizzas be x
x - 22.5 = 82.5
x = 82.5 + 22.5
x = 105 (Regular Non discounted price of 7 pizzas)
Regular Price of 7 pizzas = 105
Regular price of 1 pizza = 105 / 7 = 15

At a recent meeting, the manager of a national call center for a major Internet bank made the statement that the average past-due amount for customers who have been called previously about their bills is now no larger than $20. Other bank managers at the meeting suggested that this statement may be in error and it needs to be tested. The file called Bank Call Center attached below, contains data for a random sample of 67 customers from the call center population. What should be conducted based on the sample data? Test using α = 0.10
Answer:
As the calculated z does not fall in the critical region we fail to reject H0 and conclude that there is sufficient evidence that the average past-due amount for customers who have been called previously about their bills is now no larger than $23.
Step-by-step explanation:
As the standard deviation for the past due amounts is 63
The sample size n= 67
1) Formulate the null and alternate hypothesis
H0: u ≤ 23 against the claim Ha: u > 23
2) The test statistics is
Z= x- u / σ/ √n
z= 20- 23/ 63/ √67
z= 0.00581
z= 0.006
3) The significance level ∝= 0.1
4) The critical value for ∝= 0.1 is Z > ±2.33
5) As the calculated z does not fall in the critical region we fail to reject H0 and conclude that there is sufficient evidence that the average past-due amount for customers who have been called previously about their bills is now no larger than $23.
x² + x = 12
show the steps please
Answer:
x1 = -4
x2 = 3
Step-by-step explanation:
[tex]x^{2} + x = 12\\x^{2} +x-12=0\\x^{2} +4x-3x-12=0\\x*(x+4)-3(x+4)=0\\(x+4)*(x-3)=0\\x+4= 0 \\x-3=0\\x=-4 \\x=3\\x1=-4 \\x2=3[/tex]
Step-by-step explanation:
=> x² + x = 12
=> x² + x -12 = 0
=> x² + 4x - 3x -12 = 0
=> x ( x + 4)-3(x + 4) = 0
=> ( x + 4)(x-3)=0
=> x = 3 , -4

Tammys fish tank 18 liters of water in it. She plans to add 5 liters per minute until the tank has at least 63 liters. What are the possible numbers of minutes Tammy could add water?
Step-by-step explanation:
Hi,
63 = 5x + 18 represents this situation.
63 = 5x + 18
45 = 5x
9 = x
So, the possible number of mins are 1, 2, 3, 4, 5, 6, 7, 8, and 9.
You can also write this as x ≤ 9

The figure below consists of a square and a right triangle. Find the missing length x.
Answer:
15 cm
Step-by-step explanation:
Since the square's side length is 8 cm, and one of its sides is the short leg of the triangle, the short leg of the triangle is 8 cm
Using the pythagorean theorem, solve for b (the missing side length x)
a² + b² = c²
8² + b² = 17²
64 + b² = 289
b² = 225
b = 15
So, the missing side length is 15 cm
