What is the point-slope form?In Mathematics, the point-slope form of a straight line can be calculated by using this mathematical expression:
y - y₁ = m(x - x₁) or y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)
Where:
m represents the slope.x and y are the points.At data point (2, 20), an equation of this line in slope-intercept form can be calculated by using the point-slope form:
y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)
y - 20 = (80 - 20)/(12 - 2)(x - 2)
y = 60/10(x - 2) + 20
y = 6x - 12 + 20
y = 6x + 8

The quality control manager at a computer manufacturing company believes that the mean life of a computer is 83 months, with a standard deviation of 9 months.
If he is correct, what is the probability that the mean of a sample of 78 computers would differ from the population mean by less than 0.4 months? Round your answer to four decimal places.
Answers
The probability that the mean of a sample of 78 computers would differ from the population mean by less than 0.4 months is:
P (μ-0.4 <x<μ +0.4) = P (-0.39<x<0.39) = 0.3035
What do you mean by probability?By simply dividing the favourable number of possibilities by the entire number of possible outcomes, the probability of an occurrence can be determined using the probability formula. Because the favourable number of outcomes can never exceed the entire number of outcomes, the chance of an event occurring might range from 0 to 1. Moreover, the proportion of positive outcomes cannot be negative.
Here we have,
μ = 83,0 = 9, n = 78
Since sample size is large so we can assume normal distribution using CLT.
The z-score for x= μ-0.4 is
z=(μ-0.4-μ)/o/√n
=-0.4/9/√78
= -0.39
The z-score for x= μ +0.4 is
z=(μ+0.4-μ)/σ/√n
= 0.4/9/√78
= 0.39
The probability that the mean of a sample of 78 computers would differ from the population mean by less than 0.4 months is:
P (μ-0.4 <x<μ +0.4) = P (-0.39<x<0.39) = 0.3035.

None of the statements (1) to (6) are true about the equation. [tex]x^2-6x+2=0[/tex].
Reason why:
(1) The coefficient of the [tex]x^2[/tex] term is positive, so the graph of the quadratic equation is a parabola that opens upward. Therefore, it does not have a minimum value, but instead has a minimum point.
(2) The coordinates of the minimum point can be found using the formula x = -b/2a, which gives x = 6/2 = 3. Substituting x = 3 into the equation gives y = 2, so the minimum point is (3, 2).
(3) The point (7,-3) is not on the graph of the equation.

The lateral limits of the function g(x) at x = 4 are given as follows:
[tex]\lim_{x \rightarrow 4^-} g(x) = -4, \lim_{x \rightarrow 4^+} g(x) = 2[/tex]
How to calculate the lateral limits?
To obtain lateral limits, we need to take the limit of a function as it approaches a point from the left-hand side and the right-hand side separately.
If the two limits are equal, then this is the limit of the function, while if the lateral limits are different, then the limit of the function does not exist for the value of x.
On a coordinate plane, a curve starts at closed circle (4, negative 4), curves up to (3, negative 3), and curves down to (negative 1, negative 8), and then curves up through (negative 3, 4), hence the lateral limit to the left of x = 4, where x is less than 4, is given as follows:

11. Jenn bought 4 identical book
bags online for a total cost of
$95.65 including a flat ate of
$4.99 for shipping. Write an
equation to find the cost of each
book bag, b.
Answers
Answer:
Step-by-step explanation:
Let x be the cost of each book bag. Then, we can set up the following equation based on the information given:
4x + 4.99 = 95.65
Here, 4x represents the cost of the four identical book bags, and 4.99 is the flat rate for shipping. We add them up to get the total cost of $95.65.
To solve for x, we can first subtract 4.99 from both sides of the equation to isolate the term 4x on the left-hand side:
4x = 90.66
Then, we can divide both sides of the equation by 4 to solve for x:
x = 22.67
Therefore, each book bag costs $22.67.

Answers
The probability of both independent events A and B happening together is P(A n B) = 0.1.
What is meant by probability?
An event's probability is a numerical representation of how likely it is that the event will take place. In mathematical notation, it is written as a number between 0 and 1, or as a percentage between 0% and 100%. The higher an event's probability, the more likely it is to occur. In a sample space, there is a probability of 1 for each event. The probability formula states that the ratio between the number of favourable outcomes and the total number of outcomes determines the likelihood that an event will occur. Sets are used in the terminology of probability theory. A set is a grouping of various things.
Given,
Probability of A, P(A) = 0.2
Probability of B, P(B) = 0.4
P(A U B) = 0.5
We are asked to find P(A n B)
Now we know,
P(A U B) = P(A) + P(B) - P(A n B)
Then,
P(A n B) = P(A) + P(B) - P(A U B) = 0.2 + 0.4 - 0.5 = 0.1
Therefore the probability of both independent events A and B happening together is P(A n B) = 0.1.

What is parallelograms?A simple quadrilateral with two sets of parallel sides is known as a parallelogram in Euclidean geometry. Both sets of opposite sides are parallel and equal in a particular type of quadrilateral known as a parallelogram.
We must demonstrate that the opposing sides of ABCD's parallelogram are parallel.
CBA = DAB (Alternate interior angles)
Alternative interior angles (ABD = BAC; ADC = CBD) (Alternate interior angles)
DCA = ACD (Alternate interior angles)
Considering that AD = BC, we also have:
A + B Equals A + C. (Also on both sides)
AD = BC
Think about the two pairs of sides that are diagonally opposed: AB and CD and AD and BC.
We have these for AB and CD:
Interior angles of a quadrilateral: DAB + ABD + BCD + CDA = 180°; CBA + BAC + ADC + DCA = 180°. (Substituting corresponding angles)
We may insert them in and simplify to get: since DAB = CBA and ABD = BAC.
BCD = ADC
As a result of having the same transversal CD and equal alternative interior angles, AD and BC are also parallel. As a result, we have demonstrated that ABCD's opposing sides are parallel, proving that ABCD is a parallelogram.

per pound. How many pounds of each kind should he use in the new mix? (Round off the answers to the nearest hundredth.)
Answers
In order to create a 28-pound blend that he can sell for $1.45 per pound, the grocer should combine approximately 17.73 pounds of the less costly coffee and 10.27 pounds of the more expensive coffee.
How many pounds of each kind should he use in the new mix?Let's designate the quantity of the less expensive coffee X and the more expensive coffee Y. Since we are aware that the grocer wishes to combine 28 pounds altogether, we can write:
x + y = 28
The total profit from selling the mixture would be: 28($1.45) = $40.60 because we also know that he intends to sell it for $1.45 per pound.
The costs and quantities of the two varieties of coffee can be used to create a new equation.
0.9x + 2.4y = $40.60
With two variables in each equation, we now have two equations that we can solve by substitution or elimination. Use of substitution
28 + y = x - 0.9x + 2.4y = 40.60
0.9x + 2.4(28 - x) = $40.60
0.9x + 67.2 - 2.4x = $40.60\s-1.5x = -$26.60\sx = 17.73
We can apply the first equation to determine y now that we know x: x + y = 28.

The length of the hypotenuse is approximately 6.7.
What is the Pythagorean theorem and how is it used to find the hypotenuse of a right triangle?
The Pythagorean theorem is a fundamental relationship in Euclidean geometry that relates the lengths of the sides of a right triangle. It states that the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
Mathematically, the Pythagorean theorem can be expressed as:
[tex]c^2 = a^2+ b^2[/tex]
where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.
Finding the missing length :
In the given problem, we are given the lengths of two sides of a right triangle, which are 3 and 6. We can use these values to find the length of the hypotenuse using the Pythagorean theorem:
[tex]h^2 = 3^2+ 6^2[/tex]
[tex]h^2 = 9 + 36[/tex]
[tex]h^2 = 45[/tex]
Taking the square root of both sides gives:
[tex]h = \sqrt{45}[/tex]
Using a calculator, we can simplify this to:

The true proportion of all adults in the United States who exercise on a regular basis is between 0.384 and 0.493 with 90% confidence interval.
How to construct a confidence interval for the proportion?To construct a confidence interval for the proportion of all adults in the United States who exercise on a regular basis, we can use the formula:
CI = p ± z√(p(1-p)/n)
where:
p = proportion of the sample who exercise on a regular basis
n = sample size
z = z-score from the standard normal distribution corresponding to the desired level of confidence
Here, p = 82/187 = 0.4385 and n = 187.
A standard normal distribution table or calculator, or use the following formula:
z = invNorm((1 + C)/2)
where:
C = confidence level (expressed as a decimal)
invNorm() = inverse normal distribution function
For a 90% confidence level, C = 0.90, so:
z = invNorm((1 + 0.90)/2) = invNorm(0.95) ≈ 1.645
Substituting in the values, we get:
CI = 0.4385 ± 1.645√(0.4385(1-0.4385)/187) ≈ 0.384, 0.493

8. y> 23
y = 20, 23, 25.1, 35
Answers
Answer:
Substituting the given values of y in the inequality y > 23:
When y = 20, 20 is not greater than 23, so it's not a solution.
When y = 23, 23 is not greater than 23, so it's not a solution (it's equal).
When y = 25.1, 25.1 is greater than 23, so it's a solution.
When y = 35, 35 is greater than 23, so it's also a solution.
Therefore, the solutions of the inequality are y = 25.1 and y = 35.

(e) Find her percentile scores for the two exams.
(f) What percent of the test takers did better than her on the Verbal Reasoning section? On the Quantitative Reasoning section?
Answers
The normal distribution is N(151, 7), the z-score for verbal and quantitative reasoning are 1.29 and 0.52 respectively.
What is the short-hand for these two normal distribution(a) The shorthand for the normal distribution of the Verbal Reasoning section is N(151, 7), where 151 is the mean score and 7 is the standard deviation. The shorthand for the normal distribution of the Quantitative Reasoning section is N(153, 7.67), where 153 is the mean score and 7.67 is the standard deviation.
(b) Sophia’s Z-score on the Verbal Reasoning section is (160-151)/7 = 1.29. Her Z-score on the Quantitative Reasoning section is (157-153)/7.67 = 0.52.
(c) The Z-scores represent how many standard deviations above or below the mean Sophia’s scores are. A Z-score of 1.29 on the Verbal Reasoning section means Sophia’s score is 1.29 standard deviations above the mean score of all test takers. A Z-score of 0.52 on the Quantitative Reasoning section means Sophia’s score is 0.52 standard deviations above the mean score of all test takers.
(d) Sophia did better on the Verbal Reasoning section because her Z-score is higher for that section.
(e) To find the percentile scores, we use the standard normal distribution table. Sophia’s percentile score on the Verbal Reasoning section is the percentage of test takers who scored lower than her. Using the Z-score of 1.29 and the table, we find that her percentile score is approximately 90.7%. Her percentile score on the Quantitative Reasoning section is the percentage of test takers who scored lower than her. Using the Z-score of 0.52 and the table, we find that her percentile score is approximately 69.4%.
(f) To find the percentage of test takers who did better than Sophia on each section, we can use the standard normal distribution table again. For the Verbal Reasoning section, we need to find the area to the right of Sophia’s Z-score of 1.29. Using the table, we find that this area is approximately 9.3%. Therefore, approximately 9.3% of test takers did better than Sophia on the Verbal Reasoning section. For the Quantitative Reasoning section, we need to find the area to the right of Sophia’s Z-score of 0.52. Using the table, we find that this area is approximately 30.4%. Therefore, approximately 30.4% of test takers did better than Sophia on the Quantitative Reasoning section.

Summarize in your own words a quantity in the life-science that is modelled by a function of time. For your function, if you knew some values of its derivative, what would those values be telling you about your model? Be specific (don’t just say “rate-of-change”).
Answers
One example of a quantity in the life sciences that is modeled by a function of time is the population size of a species.
How can this be modeled?This can be modeled using a differential equation, where the rate of change of the population size is proportional to the current population size.
If we knew the values of the derivative of this function (i.e., the first derivative), we would be able to make inferences about the growth or decline of the population.
A positive derivative value would indicate that the population is growing, while a negative derivative value would indicate that the population is declining. The magnitude of the derivative would also give us information about the rate of growth or decline of the population. If the derivative is large, the population is changing quickly, while a small derivative indicates slower change.
If we had information about the second derivative of the function (i.e., the rate of change of the derivative), we would be able to make further inferences about the behavior of the population.
A positive second derivative value would indicate that the population is accelerating in its growth, while a negative second derivative value would indicate that the population is decelerating in its growth. This information could be useful in predicting future trends in population size and in making decisions about conservation efforts or resource management.

A net of a building block is shown below what is the total surface area of the building block
Answers
The total surface area of the building block is therefore (4×l×w) + (2×(b×h)/2), which is equal to (2×l×w) + bh.
What is surface area?Surface area is the total exposed area of a three-dimensional object, including the object's base area and lateral area. It is the area of the surface or outer boundary of an object and is measured in units squared such as square meters or square centimeters. Surface area is an important concept in mathematics, physics, and engineering, as it is used to calculate the amount of material needed to construct an object.
The total surface area of the building block can be found by adding the area of the six faces of the block together. To calculate the surface area of the block, we first need to find the area of each face. The six faces of the building block are four rectangular faces and two triangular faces. The area of each rectangular face can be found using the formula A=l×w, where l is the length and w is the width. The area of each triangular face can be found using the formula A=(b×h)/2, where b is the base and h is the height.
By adding the area of each face together, the total surface area of the building block can be found. The total surface area is equal to the sum of the four rectangular faces plus the two triangular faces. The total surface area of the building block is therefore (4×l×w) + (2×(b×h)/2), which is equal to (2×l×w) + bh.

This year Keisha watched 50 movies. She thought that 46 of them were very good. Of the movies she watched, what percentage did she rate as very good?
Answers
Keisha rated 92% of the movies she watched as very good.
How to find the percentage of movies that Keisha rated as very good.To find the percentage of movies that Keisha rated as very good, we can use the formula:
Percentage = (Number of movies rated as very good / Total number of movies watched) x 100%
Plugging in the values we have:
Percentage = (46 / 50) x 100%
Percentage = 92%
Therefore, Keisha rated 92% of the movies she watched as very good.

In 50 words or fewer, describe the relationship between the volumes of a cylinder
and a cone that have the same size base and equal heights.
Answers
These figures have curved surfaces, not flat faces. A cylinder is similar to a prism, but its two bases are circles, not polygons. Also, the sides of a cylinder are curved, not flat. A cone has one circular base and a vertex that is not on the base.
When a cone and cylinder have the same height and radius the cone will fit inside the cylinder. The volume of the cone will be one-third that of the cylinder. If the radius or height are different, then there is no relationship between them.
