We have,
a.
Probability questions based on selecting a sample of 100 computers:
- What is the probability that exactly 5 computers in the sample need warranty service?
- What is the probability that more than 10 computers in the sample need warranty service?
- What is the probability that at least 2 computers in the sample need warranty service?
- What is the probability that none of the computers in the sample need warranty service?
- What is the probability that the proportion of computers needing warranty service in the sample is greater than 0.3?
These questions can provide insights into the likelihood of certain outcomes within the sample of 100 computers.
b.
Inferential statistics question that can be answered by determining the number of computers needing warranty service in a sample of size 100:
"What is the estimated proportion of computers in the population that need warranty service based on the observed proportion in the sample?"
By determining the number of computers in the sample of 100 that need warranty service, we can use inferential statistics to make an estimate or inference about the proportion of the entire population of computers of that brand and model that may require warranty service.
This can help in understanding the warranty service needs of the entire population based on the information gathered from the sample.
Thus,

Write the equation in slope-intercept form of a line that has a slope of 1/3 and passes through the point (-6, 0). y=1/3x, y=1/3x-6, y=1/3x-2, y = 1/3x+ 2
Answer:
Option D: [tex]y=\frac{1}{3}x+2[/tex] is the correct answer.
Step-by-step explanation:
Given that:
Slope of the line = 1/3
Point = (-6,0)
Slope-intercept form of a line is given by:
y = mx + b
We will put the slope and point in the equation to find b.
[tex]0=\frac{1}{3}(-6)+b\\0=-2+b\\b=2[/tex]
Slope intercept form of the given line is;
[tex]y=\frac{1}{3}x+2[/tex]
Hence,
Option D: [tex]y=\frac{1}{3}x+2[/tex] is the correct answer.
What is the equation of the line in slope-intercept form?
Answer:
y = -1/6x + 4
Step-by-step explanation:
Use the equation y = mx + b (format of the equation of the line)Choose two random points on the line. I'll choose (0,4) and (6,3) because they're easiest to identifyFinding the slope (m) Format it as [tex]\frac{y^2-y^1}{x^2-x^1}[/tex] and solve --> [tex]\frac{3-4}{6-0}[/tex] --> -1/6Finding the y-intercept (b) Substitute the information you currently have into the equation y = mx + b --> 4 = (-1/6)(0) + b --> b = 4Now that you have your slope and y-intercept, substitute it into the equation. Your final answer is y = -1/6x + 4A number c minus 6 is less than or equal to 5.3. Write this word sentence as an inequality.

11. Four less than a number tripled is the same number increased by ten.
What is the number?
Answer:
7
Step-by-step explanation:
first, we would set up an equation. let 3x-4 represent "four less than a number tripled". "a number" would be represented by x. let x+10 represent "the same number increased by 10".
set 3x-4 and x+10 equal to each other:
3x-4=x+10
next, we would solve this equation for x. first we would get the x together on one side of the equation. we would do this by subtracting x from both sides to remove it from the right side of the equation:
2x-4=10
then, we would get the 2x by itself. we would do this by adding 4 to both sides:
2x=14
finally, we would divide each side of the equation by 2 to find x:
x=7.
The number is 7.

Which equation represents a circle with its center at (2, -3) and that passes through the point (6,2)?
Answer:
An equation represents a circle with its center at (2, -3) and that passes through the point (6,2) is:
(x - 2)² + (y + 3)² = 41
Step-by-step explanation:
The standard equation of a circle having the center at point C(x₀, y₀) and radius r is given by
(x - x₀)² + (y - y₀)² = r²
It means that every point P(x, y) belonging to the circle must satisfy the equation.
In this particular case, we have that the circle passing through P(x, y) = (6, 2) and the center C(x₀, y₀) = (2, -3).
Then substituting these values in the formula:
(x - x₀)² + (y - y₀)² = r²
(6 - 2)² + (2 - (-3))² = r²
switch sides
r² = (6 - 2)² + (2 - (-3))²
r² = (4)² + (2 + 3)²
r² = (4)²+ (5)²
r² = 16 + 25
r² = 41
r = √41, r = -√41
As r can not be negative, so
r = √41
Therefore , the equation of the circle with center at C = (2, -3) and radius r = √41 is:
(x - 2)² + (y + 3)² = (√41 )²
(x - 2)² + (y + 3)² = 41
Therefore, an equation represents a circle with its center at (2, -3) and that passes through the point (6,2) is:
(x - 2)² + (y + 3)² = 41

Gerri says that if a number is a multiple of 9 it is also a multiple of 3. Do you agree ? Explain
Yes, Gerri is correct and if a number is a multiple of 9 it is also a multiple of 3.
What is a factor?
A factor is a number that completely divides another number. To put it another way, if adding two whole numbers results in a product, then the numbers we are adding are factors of the product because the product is divisible by them.
Here, we have
Gerri says that if a number is a multiple of 9 it is also a multiple of 3.
Since 3 is a factor of 9, anything 9 can go into, 3 can also go into.
3x3=9
So, whenever 9 can go into something, it will take 3 times as many 3s to go into that number.
Example:
3 nines = 27
9 threes = 27
9 is 3 times as many as 9.
Hence, Gerri is correct and if a number is a multiple of 9 it is also a multiple of 3.

Answer:
Remember, 3 is the same thing as 3/1. Before we can divide, we need to make one more change. We'll switch the numerator and the denominator of the fraction we're dividing by: 1/3 in this example. So 1/3 becomes 3/1.

Which equation represents h(x)?
HURRY TIMED
Answer:
the last one
Step-by-step explanation:
The equation that represents h(x) = g(x) – f(x) which is correct answer would be option (D)
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
From the given table, the values of x, f(x), g(x), and h(x) are given and there are corresponding values.
Therefore, the corresponding values for
When x = 1
f(x) = 3
g(x) = 18
h(x) = 18 - 15 = 3
When x = 2
f(x) = 12
g(x) = 21
h(x) = 21 - 12= 9
When x = 3
f(x) = -3
g(x) = 24
h(x) = 24 - (-3) = 27
Hence, The equation that represents h(x) = g(x) – f(x).

Answer:
The 3 positive whole numbers would be:
5, 5 , 14
Step-by-step explanation:
We need to find 3 positive whole numbers
The mode is 5
The median is 5
The range is 5
If the mode is 5 it means 5 is most repeated number, as mode is most repeated number of series.
So, it means we have two 5
We know that range can be found by: [tex]Range=Maximun\:Value-Minimum\:Value[/tex]
If we consider minimum value to be 5
[tex]9=Maximun\:Value-5\\Maximun\:Value=9+5\\Maximun\:Value=14[/tex]
So, the 3 positive whole numbers would be:
5, 5 , 14
