In both cases, the sample proportion is very likely to be within a certain range of the population proportion, with a probability of 1.0000 or 100%.
What is probability?
Probability is a measure of the likelihood that an event will occur, it is a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event.
In this case, we are interested in the probability that the sample proportion (p) will be within a certain range of the population proportion (0.30).
a. To find the probability that the sample proportion will be within ±0.03 of the population proportion, we can use the standard normal distribution (z-table). The standard normal distribution is a normal distribution with a mean of 0 and a standard deviation of 1.
The formula for the standard normal distribution is:
z = (p - 0.30) / (standard deviation of p)
The standard deviation of p is given by the formula:
(population proportion * (1 - population proportion)) / sample size
In this case, we have:
(0.30 * (1 - 0.30)) / 150 = 0.0006
So, the standard deviation of p is 0.0006
The probability that the sample proportion will be within ±0.03 of the population proportion is the same as the probability that the sample proportion will be between 0.27 and 0.33.
Therefore, we can calculate the z-score for the lower and upper bounds of the range:
z1 = (0.27 - 0.30) / 0.0006 = -5
z2 = (0.33 - 0.30) / 0.0006 = 5
Using the z-table, we can find the probability that a z-score falls between -5 and 5.
The probability that the sample proportion will be within ±0.03 of the population proportion is:
P(z1 <= z <= z2) = P(-5 <= z <= 5) = 1 - 0.0000 = 1.0000
b. To find the probability that the sample proportion will be within ±0.08 of the population proportion, we can use the same formula as before. The probability that the sample proportion will be within ±0.08 of the population proportion is the same as the probability that the sample proportion will be between 0.22 and 0.38.
Therefore, we can calculate the z-score for the lower and upper bounds of the range:
z1 = (0.22 - 0.30) / 0.0006 = -10
z2 = (0.38 - 0.30) / 0.0006 = 10
Using the z-table, we can find the probability that a z-score falls between -10 and 10.
The probability that the sample proportion will be within ±0.08 of the population proportion is:
P(z1 <= z <= z2) = P(-10 <= z <= 10) = 1 - 0.0000 = 1.0000
Hence, In both cases, the sample proportion is very likely to be within a certain range of the population proportion, with a probability of 1.0000 or 100%.

In the xy-plane, line m passes through the origin and is perpendicular to the line 6x+y=h, where h is a constant. If the two lines intersect at point (p, p+2), what is the value of p?
Using slope intercept equation the value of p is -2.4 .
What is slope intercept equation?
When the slope of the line being studied is known, and the provided point is also the y intercept, the slope intercept formula, y = mx + b, is utilised (0, b). It provides both a slope and an intercept, which is why the form is known as the slope-intercept form.
Let’s call line m y’ and we can deduce that y’ = ax where a is the slope of line y’. (In the standard line equation, y = mx + b, b is the y intercept which, in the case of line m, is zero since it passes through the origin (0,0).)
Then name the 2nd line y’’ = -6x + h
When straight lines are perpendicular, their slopes are negative inverses. So the slope of line y’, which I’ve called a, must equal +1/6
Now we know that y’ = (1/6)x and y’’ = -6x + h
If the lines intersect at a point (x , y) which we are told is (p, p+2), then at that point y’ = y’’, or p+2 = (1/6) and p = -6(p+2) + h.
From this we can solve for p,
=> p - p/6 = -2=> (5/6)p = -2 or
=>p = -12/5 = -2.4
Now we know that the intersection point (p,p+2) is (-2.4, -0.4)
Hence the value of p is -2.4 .

Write the equation of the line that passes through the point (0, 1) and is perpendicular to the line y=1/5x+2
Answer:
the requisite equation for the given question is y=−5x
Step-by-step explanation:
firstly, select the coordinates (0, 0) through which the perpendicular line will cross (0,0)
then, locate the slope when y=15x+2y=15x+2.
The slope is 1/5 when expressed in the slope-intercept format.
therefore, m=1/5
since, a perpendicular line's equation must have a slope equal to the inverse reciprocal of its initial slope.
therefore, [tex]m_{perpendicular}[/tex]=−1/(1/5)
To determine the slope of the perpendicular line, simplify 1/(1/5).
[tex]m_{perpendicular}[/tex]=−5
By using point-slope method, determine the perpendicular line's equation.
y+0=−5.(x+0)
Solve for y.
y= -5x + 0
y=−5x
hence, the answer for the question is y=-5x

Answer: 20
Step-by-step explanation: Hello! The first thing you have to do is substitute m = 7 and n = 5 into the equation 4 + (m - n)^4. After substituting m and n into the equation, you will get: 4 + (7 - 5)^4. Use PEMDAS (parentheses, exponents, multiplication, division, addition, and subtraction). Parentheses is first, so solve everything inside of the parentheses first. 7 - 5 = 2. Now you have 4 + (2)^4. Next is exponents in pemdas, so solve the exponents. 2^4 = 2 x 2 x 2 x 2, or 4 x 4, or 16. Now you have 4 + 16. The last thing you have to do is add 4 + 16, which is 20. The answer is 20.

This graph shows a proportional relationship.
What is the constant of proportionality?
y= 1/4 x= 3/8
Answer:
y = 1/4x
Step-by-step explanation:
Proportional Relationships:A proportional relationship is similar to a linear relationship, with one distinction, it's y-intercept is equal to zero, so it can be expressed in the form: [tex]y=kx[/tex], where "k" is some constant. More specifically, when we divide y by x, we always get a constant amount, denoted as "k": [tex]\frac{y}{x}=k[/tex].
Using this knowledge, we can kind of immediately tell it's [tex]y=\frac{1}{4}x[/tex] as it's the only one in the form: [tex]y=kx[/tex], but let's look at why [tex]x=\frac{3}{8}[/tex] is not a proportional relationship.
It's important to note that [tex]x=\frac{3}{8}[/tex] is a vertical line, since the x value is constant while the y value varies. This means "y/x" cannot be constant, since "y" changes, except what it's being divided by will remain the same, equal to 3/8.

In reference to different sampling methods, systematic sampling includes the steps: divide the population into groups; use simple random sampling to identify a proportionate number of individuals from each group: [FALSE]
What is Systematic sampling?Systematic sampling is a method of sampling where the sample is selected using a fixed interval, rather than using random sampling. The sampling process begins by selecting a random starting point in the population and then selecting every kth element from the population.
For example, if the population has 100 elements and k=10, every 10th element would be selected for the sample.
Dividing the population into groups, and then using simple random sampling to identify a proportionate number of individuals from each group is a method called stratified sampling.
It is important to note that systematic sampling can be vulnerable to sampling bias if the sampling interval is not chosen carefully and the population is not randomly ordered, because in that case, it will not be a truly random sample.

The function are f+g(x)=f(x)+g(x), (f-g)x=f(x)-g(x), (g-f)(x)=g(x)-f(x), (f.g)(x)=f(x).g(x), f/g(x)=f(x)/g(x) and g/f(x)=g(x)/f(x)
What is a function?A relation is a function if it has only One y-value for each x-value.
We know that from properties of function,
f+g(x)=f(x)+g(x)
(f-g)x=f(x)-g(x)
(g-f)(x)=g(x)-f(x)
(f.g)(x)=f(x).g(x)
f/g(x)=f(x)/g(x)
g/f(x)=g(x)/f(x)
Hence, the function are f+g(x)=f(x)+g(x), (f-g)x=f(x)-g(x), (g-f)(x)=g(x)-f(x), (f.g)(x)=f(x).g(x), f/g(x)=f(x)/g(x) and g/f(x)=g(x)/f(x)

What is a rectangle?A rectangle is a quadrilateral with four right angles. It can also be defined as: an equiangular quadrilateral, since equiangular means that all of its angles are equal; or a parallelogram containing a right angle. A rectangle with four sides of equal length is a square.
here, we have,
Since the measurements in meters are multiples of 4, it makes this problem a little easier.
First you divide 8 by 4 to get 2
Then divide 16 by 4 to get 4
After that you're going to multiply 3 units by both quotients separately.
So you multiply 3 by 2 to get 6
Then you multiply 3 by 4 to get 12
So, then you end up with a 6 unit by 12 unit drawing.
therefore, the answer is 6 units by 12 units.

In year 2015 the sum of the age of maria, her mother, and her father, will be 100 years.
As the date and month of the birth is same for maria, her mother, and her father. Lets say in year X, the sum of the age will be 100 years.
The age of maria in year X = (X - 2000)
The age of her mother in year X, = (X - 1975)
The age of her father in year X, = (X - 1970)
Sum of their age,
100 = (X - 2000) + (X - 1975) + (X - 1970)
100 = 3X - (2000 + 1975 + 1970)
100 = 3X - 5945
3X = 5945 + 100
3X = 6045
X = 2015

If the equation for every x and x in the domain of f holds, then a function f is odd. −f(x)=f(−x) − f ( x ) = f ( − x )
What is meant by odd function?If the equation for every x and x in the domain of f holds, then a function f is odd. −f(x)=f(−x) − f ( x ) = f ( − x ) An odd function has a graph that, geometrically speaking, is rotationally symmetric with respect to the origin, meaning that the graph is unaffected by a 180° rotation of the origin.
An even function exists if an expression is obtained that is equivalent to f(x); an odd function exists if an expression is obtained that is equivalent to -f(x); and neither occurs, in which case it is neither.
An odd function is a function having a symmetrical graph about the origin. If a function doesn't display either symmetry, it cannot be either even or odd.

Determine the measure of Angle B in the triangle below. thank you
Answer:
55°
Step-by-step explanation:
2x + 5 + 2x + 3x = 180 Combine like terms The sum of the interior angles of a triangle is 180
7x + 5 = 180 Subtract 5 from both sides
7x + 5 - 5 = 180 - 5
7x = 175 Divide both sides by 7
[tex]\frac{7x}{7}[/tex] = [tex]\frac{175}{7}[/tex]
x = 25
Substitute 25 for x
2x + 5
2(25) + 5
50 + 5
