Slope intercept form: [tex]y=mx+b[/tex]
m = slopeb = y-interceptWe can identify two points on the given graph and solve for the slope and the y-intercept.
Solving the QuestionTwo clear points on the graph are (6,0) and (0,6).
First, we can solve for the slope by using the slope equation:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex] where two points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
⇒ Plug in the points (6,0) and (0,6):
[tex]m=\dfrac{0-6}{6-0}\\\\m=\dfrac{-6}{6}\\\\m=-1[/tex]
Therefore. the slope of the line is -1. Plug this into [tex]y=mx+b[/tex]:
[tex]y=-x+b[/tex]
Now, we can find the y-intercept. It is the value of y when the line crosses the y-axis.
In this case, we can see on the graph that this is 6.
[tex]y=-x+6[/tex]

A box is to be made by cutting a square measuring 4 centimeters on a side from a square piece of cardboard. If the volume of the box is to be 100 cubic centimeters, find the length of a side of the original square. Round the answer to the nearest tenth of a centimeter.
Answers
Given the volume of the box is 100 cm^3
And to made the box we need to cut a square measuring 4 centimeters on a side from a square piece of cardboard.
so, the height of the box = 4 cm
so, the volume = height * area of the base
100 = 4 * area of the base
Area of the base = 100/4 = 25 cm^2
so, the side length of the base of the box =
[tex]\sqrt[]{25}=5[/tex]so, the lenght of the a side of the original square = 5 + 2*4 = 5 + 8 = 13 cm

What is meant by length of side?By dividing the base's length by its height, one may calculate any quadrilateral's surface area. We can conclude that all of the sides are the same length because the shape is square. Using the square root of the area to determine the length of one side, we can then work backwards from this information. A square has four sides, thus to determine the length of one side, divide the perimeter by 4. Assumed Area: Since s2 is the formula for a square's area and that number corresponds to one of its sides, you must get the square root of the area. A side is the line segment that connects two vertices of a shape or two-dimensional figure according to the definition of geometry.
Length of SU
= RS - RT - TU
= 24 - 12 - 6
= 24 - 1
= 6
Thus, the length of the US is 6 units.

Answer:
y = - [tex]\frac{1}{3}[/tex] x + [tex]\frac{8}{3}[/tex]
Step-by-step explanation:
the perpendicular bisector of AB passes through the midpoint of AB at right angles.
find the midpoint using the midpoint formula
with A (- 2, 0 ) and B (0, 6 )
midpoint = ( [tex]\frac{-2+0}{2}[/tex] , [tex]\frac{0+6}{2}[/tex] ) = ( [tex]\frac{-2}{2}[/tex] , [tex]\frac{6}{2}[/tex] ) = (- 1, 3 )
find the gradient m of AB using the gradient formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = A (- 2, 0 ) and (x₂, y₂ ) = B (0, 6 )
m = [tex]\frac{6-0}{0-(-2)}[/tex] = [tex]\frac{6}{0+2}[/tex] = [tex]\frac{6}{2}[/tex] = 3
given a line with gradient m then the gradient of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{3}[/tex]
the equation of a line in gradient- slope form is
y = mx + c ( m is the gradient and c the y- intercept )
here m = - [tex]\frac{1}{3}[/tex] , then
y = - [tex]\frac{1}{3}[/tex] x + c ← is the partial equation
to find c substitute (- 1, 3 ) into the partial equation
3 = [tex]\frac{1}{3}[/tex] + c ⇒ c = 3 - [tex]\frac{1}{3}[/tex] = [tex]\frac{8}{3}[/tex]
y = - [tex]\frac{1}{3}[/tex] x + [tex]\frac{8}{3}[/tex] ← equation of perpendicular bisector

What is markup?As stated, markup is the distinction between a product's selling price and its cost price. Retail minus Cost is markup. The term "markup" describes the discrepancy between a product's selling price and its actual cost. It is specified as a percentage over the price. In other words, the seller makes a profit when the price of the commodity or service is higher than the overall cost. A unit's gross profit, which is the sales price less the cost to create or buy it for resale, is divided by its cost to determine the markup %. The markup percentage is computed as (12 - 8) / 8 and is equal to 50% if an item costs the business $8 to produce but is sold for $12.

Answers
A lift ratio of 1.52 implies that identifying a person who purchases coffee and a breakfast sandwich is 52% better than guessing that a random person will purchase a breakfast sandwich.
What is the lift ratio about?Stronger relationships are indicated by higher lift values.We divide the confidence ratio by the support of the consequent to arrive at the lift ratio.
Lift ratios greater than one are typically thought to imply a significant link between the components. Lift ratios below 1 indicate that a purchase of the items is unlikely. Lift is simply the ratio of target response divided by the average response.

the length of pregnancy isn't always the same. in pigs, the length of pregnancies varies according to a normal distribution with mean 114 days and standard deviation 5 days. what percent of pig pregnancies are longer than 109 days?
Answers
95.61 percent of pig pregnancies are longer than 109 days with 0.8413 probability.
A standard normal distribution or z-table can be used to approximate the probability of multiple ranges of values for a random normal variable X with a particular mean and standard deviation. This method entails changing X to a typical normal variable Z.
The normal, random variable X equals the length of pregnancy.
The mean and standard deviation are then calculated.
u, Mean = 114 days
σ, Standard deviation = 5 days
Then, as follows, transform X to its standard normal variable:
Z = (X - u) ÷ σ
Z = (X - 114) ÷ 5
To determine the likelihood of a pregnancy lasting more than 109 days,
P(X ≤ 109) = P(Z ≤ 114 - 109 ÷ 5)
P(X ≤ 109) = P(Z ≤ 1)
P(Z ≤ 1) = 0.8413 when using a typical normal distribution or z-table.

Answers
35 encyclopedias can be fit on the bookrack.
What is an encyclopedia?
An encyclopedia (American English) or encyclopaedia (British English) is a reference source or compendium that provides summaries of general or specific information to a certain topic or discipline. Encyclopedias are organized into articles or entries that are either alphabetically sorted by article name or by subject categories, or are hyperlinked and searchable by random access. The entries in encyclopedias are longer and more thorough than those in most dictionaries. In general, encyclopedia articles focus on factual information about the subject specified in the title, as opposed to dictionary entries, which focus on linguistic information about words, such as their derivation, meaning, pronunciation, use, and grammatical forms.
Width of bookrack = 61 1/4 inches
Width of an encyclopedia = 1 3/4 inches
no. of encyclopedias to be fit = (61 1/4)/(1 3/4)
= (245/4)/(7/4)

Answers
The probability that the diameter of a selected bearing is greater than 152 millimeters is 64.05%.
What is termed as the z-score?The Z-score indicates how far the measure deviates from the mean. After determining the Z-score, we examine the z-score table to determine the p-value affiliated with this z-score. This p-value represents the probability that the measure's value is less than X, or the percentile of X.For the given question;
The data for the ball bearing is given as-
mean diameter μ = 139 millimetersvariance σ = 36 millimeterssample mean x = 152 millimetersZ-score = (x - μ)/σ
Put the values;
z = (152 - 139)/36
z = 0.36
P(x > 125) = P(z > 0.36), see p values from z table for 0.36.
P(x > 125) = 0.6405
P(x > 125) = 64.05%
Thus, the probability that the diameter of a selected bearing is greater than 152 millimeters is 64.05%.

Using angle sum property we found that ∠ x = 113°, ∠y = 67° and ∠z = 49°
What is angle sum property of a triangle?The angle sum property of triangle states that the sum of all the interior angles of a triangle is 180°.
If ΔABC is a triangle then,
m ∠A + m ∠B + m ∠C = 180°
Given from the figure in the question that 28°, 39° and x° are interior angles of a triangle, then using angle sum property:
28° + 39° + x° = 180°
⇒ 67° + x° = 180°
⇒ x° = 180° - 67° = 113°
∠x and ∠y are on the same line same point therefore their sum will be 180°
⇒ x° + y° = 180°
⇒ 113° + y° = 180°
⇒ y° = 180° - 113° = 67°
Also an exterior angle of a triangle is equal to sum of interior opposite angles.
∴ y ° = 28° + 39° = 67°
Now, 64° , y° and z° are interior angles of same triangle from the figure in the question.
∴ Using angle sum property,
64° + y° + z° = 180°
⇒ y ° + z° = 180° - 64° = 116°
⇒ y° + z° = 116°
⇒ z° = 116° - y° = 116° - 67° = 49°
Therefore ∠x, ∠y , ∠z are 113° , 67° and 49° respectively
