Answer:
Step-by-step explanation:
When taking 100 samples of size 30 or greater from a population, exactly 95 of them will create a confidence interval that contains the true population mean. True or false?
This statement is false, or better still, ambiguous. 100 samples of size 30 (or greater) each, means 300 total and it can't be just 95 of them that will contain the true population mean.

Find the general solution of the given system.
dx dt = 6x − y
dy dt = 36x − 6y
Answer:
[tex]y = 6x + C[/tex]
Step-by-step explanation:
Given the system of equations
dx/dt = 6x − y ............. 1
dy/dt = 36x − 6y ............ 2
Divide equation 2 by 1;
[tex]\dfrac{dy/dt}{dx/dt} = \dfrac{36x-6y}{6x-y} \\\\\dfrac{dy/dt}{dx/dt} = \dfrac{6(6x-y)}{6x-y}\\ \\\dfrac{dy/dt}{dx/dt} = 6\\\\\dfrac{dy}{dt}* \dfrac{dt}{dx} = 6\\\dfrac{dy}{dx} = 6[/tex]
cross multiply
[tex]dy = 6dx\\[/tex]
integrate both sides of the expression
[tex]\int\limits {dy} = \int\limits {6} \, dx \\\\y = 6x + C[/tex]
Hence the general solution to the system of equation is [tex]y = 6x + C[/tex]

(02.05 MC) Graph g(x), where f(x) = 3x − 1 and g(x) = f(x + 1).
We Need To Graph:
2.05 MC
g(x)
f(x) = 3x-1
g(x) = f(x+1)
The graph is shown in the diagram.
What is a Graph?A graph is a representation of the relationship between two variables that are normally measured along one of a pair of axes at right angles.
As per the given data:
f(x) = 3x − 1
g(x) = f(x + 1).
For g(x) substituting (x+1) in f(x):
g(x) = 3(x+1) - 1
g(x) = 3x + 3 - 1
g(x) = 3x + 2
∴ y = 3x + 2
For graph using the x and y intercept:
y intercept {x=0}:
y = 2
x intercept {y=0}:
x = (-2)/3
The graph will as drawn in the diagram and the line will pass through the points [(-2)/3, 0] and [0, 2].

The change will be a whole dollar amount, which can be negative, zero, or positive. Thus the change will be a(n
Answer:
Integer number
Step-by-step explanation:
A "whole dollar" amount means, there's no decimal point, or cents in the dollar amount.
This represents a whole number, which is an integer.
It is an integer because we are told that the while dollar amount could be negative, positive or zero.
A number that is zero, positive or negative, which is also not a fraction nor a decimal, meets the true definition of what can be referred to as an integer.
Thus, the whole dollar amount change could be 0, -4, 4.
the admission fee to an amusement park is $17. It costs an additional c dollars to rent a locker to hold your belongings. the total cost for 10 to enter the amusement park and each rent a locker is $260 how much does it cost for one person to rent a locker
Answer:
$9
Step-by-step explanation:
$260-$170=90
90/10=9
We know that $17 * 10 = $170
c = amount of money to rent a locker.
$170 + 10c = $260
Subtract $170 from both sides.
10c = $90
Divide both sides by 10
c = $9
It cost $9 for one person to rent a locker.

Quiz scores of statistics students were obtained by a teacher and listed below. Construct a frequency distribution beginning with a lower class limit of 0 and use a class width of 2. What upper class boundary of the fifth class? 8,6,2,4,2,0,2,6,7
Answer:
The frequency distribution is
The frequency distribution is
S/N Class limit Frequency
1 0-2 4
2 3 -4 1
3 5-6 2
4 7-8 2
5 9 - 10 0
6 11 - 12 0
The value for value upper class boundary of the fifth class is [tex]CB_5 = 10.5[/tex]
Step-by-step explanation:
From the question we are told that
The lower class limit is 0
The class width is 2
The scores is 8,6,2,4,2,0,2,6,7
The frequency distribution is
S/N Class limit Frequency
1 0-2 4
2 3 -4 1
3 5-6 2
4 7-8 2
5 9 - 10 0
6 11 - 12 0
Generally the upper class boundary of the fifth class is mathematically represented as
[tex]CB_5 = \frac{10 + 11}{2}[/tex]
[tex]CB_5 = 10.5[/tex]
Use the Squeeze Theorem to show that [tex]\lim_{t \to \infty} \frac{cos5t}{5t}[/tex]
Complete the following argument: for t arbitrary large and positive.
Im not sure how to break this problem down using the Squeeze Theorem, could anyone help?
Recall that [tex]\cos x[/tex] is bounded between -1 and 1 for all real [tex]x[/tex], so that
[tex]-1\le \cos(5t)\le 1[/tex]
[tex]\implies-\dfrac1{5t}\le\dfrac{\cos(5t)}{5t}\le\dfrac1{5t}[/tex]
Now take the limit of each side of the inequality:
[tex]\displaystyle\lim_{t\to\infty}\left(-\dfrac1{5t}\right)\le\lim_{t\to\infty}\dfrac{\cos(5t)}{5t}\le\lim_{t\to\infty}\dfrac1{5t}[/tex]
The bounding limits are both 0, so by the squeeze theorem the desired limit is also 0.
Muna is making a scale drawing of a gecko. The gecko is 1:2 inch wide and 5 inches long. she decides to make her drawing of the gecko 1 inch wide. How long will the drawing be ? show your work
Answer:
L= 0.83 in
Step-by-step explanation:
Width= 1.2 in when length = 1 in
Required
Determine the length when width = 1 in
First, we need to determine the ratio
Ratio = [tex]\frac{Width}{Length}[/tex]
Ratio = [tex]\frac{1.2}{1}[/tex]
Ratio = 1.2 ---(1)
Let the required length be represented with L
So:
Ratio = [tex]\frac{Width}{Length}[/tex]
Ratio = [tex]\frac{1}{L}[/tex] ---(2)
Equate (1) and (2)
[tex]\frac{1}{L}[/tex] = 1.2
Multiply through by 1.2
L * [tex]\frac{1}{L}[/tex] = 1.2 * L
1 = 1.2 * L
Divide through by 1.2
L = [tex]\frac{1}{1.2}[/tex]
L = 0.83 in (Approximated)

Express the confidence interval 0.491 ± 0.057 in the form of p-E < p
A) 0434 B) 0.434 C) 0.491 D) 0.4625 < p <0.5195.Answer:
0.424<0.538
Step-by-step explanation:
Given the confidence interval 0.491 ± 0.057, we are to express in the form
p-E < p + E where E is the error
From the interval E = 0.057, p = 0.591
p±E = (p+E, p-E)
0.491 ± 0.057 = (0.491-0.057, 0.491+0.057)
0.491 ± 0.057 = (0.434, 0.548)
Hence the interval in the form
p-E < p + E is 0.424<0.538

The altitude of a helicopter increases 1000 feet every 4 minutes.
What is the unit rate of change (feet per minute) of the altitude?
Answer:
250 feet per minute
Step-by-step explanation:
1000 divided by 4 is 250. You divide them by each other because if you multiply 250 feet by 4 minutes, you get 1000.
The unit rate of change is 250ft/min
Rate of changeThis is change in distance with respect to time
Given the following parameters;
Distance covered = 1000feetTime taken = 4 minutesGet the unit rate of change as shown:
Unit rate = Distance/Time
Units rate = 1000/4
Unit rate = 250 ft/min
Hence the unit rate of change is 250ft/min

Suppose that $9000 is placed in an account that pays 2% interest compounded each year. Assume that no withdrawals are made from the account. Follow the instructions below. Do not do any rounding. (a) Find the amount in the account at the end of 1 year. (b) Find the amount in the account at the end of 2 years.
Answer:
First year would be 9180 and the second year would be 9363.6
Step-by-step explanation:
I just take the interest 2% make it a decimal .02 and times that by 9000 which gives you 180 then just add that to the 9000 for the first year and then for the second take 9180 times .02 which gives you 183.6 and just add that too 9180 to get 9363.6

C. Rational
Step-by-step explanation:
A whole number is where it is counting from 0 and going up. A integer is any number and their opposites. Irrational is something like pi or something like that.
The given mixed fractional number is a rational number. The correct option is C.
What is a rational number?A rational number is one that can be stated mathematically as the ratio or fraction p/q of two numbers, where p and q are the numerator and denominator, respectively.
Irrational numbers are all real numbers that are not rational numbers in mathematics. Irrational numbers, on the other hand, cannot be stated as the ratio of two integers. Decimal notation is the term used to describe the method of representing numbers in the decimal system.
Given the number is 3(2/3) convert the number into the decimal form.
3(2/3) = 11/3 = 3.66666667
The decimal form of the number indicates that the number is nonrepeating and terminating. It can be written in the fractional form

Use the figure to write the segment addition postulate, write an equation and solve for x.
Answer:
5). x = -1
6). x = 2
Step-by-step explanation:
5). AC = (x + 10)
AB = 5
BC = (2x + 6)
By segment addition postulate,
AC = AB + BC
(x + 10) = 5 + (2x + 6)
x + 10 = 2x + 11
2x - x = 10 - 11
x = -1
6). AC = 19
AB = 9x + 7
BC = -3x + 20
By segment addition postulate,
AC = AB + BC
39 = 9x + 7 + (-3x + 20)
