In order to design an appropriate touchscreen for a computer, the manufacturer has to consider the average size of the fingers and hands that will be touching the screen. One lab found that the average width of the index ( or pointing ) finger for adults is from 1.6 cm to 2 cm wide.
1. All the measurements on this page are inclusive. Explain what that means for the inequality symbols you will use.
2. Write the average width as an inequality using centimeters.
3. One centimeter = 0.39 inches. Write the average width as an inequality using inches.
The range of the average width of the index finger which is between 1.6 centimeters and 2 centimeters gives;
1. The symbols to use for the inequality are ≤ and ≥
2. The average width expressed as an inequality is; 1.6 ≤ w ≤ 2
3. The inequality for the average width in inches is 0.624 ≤ w ≤ 0.78
How can the inclusive range be expressed as an inequality?1. With regards to working with number ranges or intervals, the term inclusive means that the endpoints of the (closed) interval are included in the range.
The inequality symbol to be used in an inclusive interval are ≤ and ≥ (the symbols < and > are used for an exclusive measurements)
2. The minimum width = 1.6 centimeters
Maximum width = 2 centimeters
The average width in centimeters, w, written as an inequality is therefore;
1.6 ≤ w ≤ 23. The given conversion factor is 1 cm. = 0.39 inches.
Therefore;
1.6 cm = 1.6 × 0.39 in. = 0.624 in.
2 cm = 2 × 0.39 in. = 0.78 in.

16 = -4(-3) + 4 is an equation in slope-intercept form for the line passing through points (-4,16) and (3,-5)
What is a slope of line?A line's steepness and direction are determined by the slope of the line. Without actually using a compass, determining a line's slope in a coordinate plane allows one to anticipate whether a line is parallel, perpendicular, or not.
The change in a line's y coordinate relative to its change in x coordinate is referred to as the line's slope. Δy is the net change in the y coordinate, while Δx is the net change in the x coordinate.
Therefore,
m = y₂-y₁/x₂-x₁ (where m denotes the slope) can be used to express how the y coordinate changes in relation to the x coordinate.
Be aware that tan ∅ = y/x
We also refer to this tan as the line's slope.
We have been asked to write an equation in slope-intercept form for the line passing through (-4,16) and (3,-5)
First we will find the slope(m)
We know that slope = m = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]
For the pairs of points (-4,16) and (3,-5)
⇒ m = [tex]\frac{-5- 16}{3 - (-4)}[/tex]
⇒ m = [tex]\frac{-21}{7}[/tex]
⇒ m = -3
We know that the equation for slope(m) and y - intercept(b) of a line is given by :
y = mx + b
Here lets take equation 16 = -4(-3) + b .Here x and y is substituted with the second two points.
⇒ 16 = -4(-3) + b
⇒ 16 = 12 + b
⇒ b = 16 - 12
⇒ b = 4
The equation in the slope intercept is as follows:-
16 = -4(-3) + 4

The Central Islip community has 9,649 homes in it. Smart Boards cost the school district $5,200 each. The HS needs 175, the Reed School needs 150 and the Mulligan school needs 50 new boards. Network Outsource the schools tech company has 12 workers for the HS, 8 for the Reed School and 4 for Mulligan. They all work 8 hours a day. They work 5 days a week, Monday thru Friday. They earn $58 per hour. It will take 45 weeks to finish the job. Find: a) Total Product Cost b) Total Labor Cost c) Total Cost d) Cost per Home e) Cost per Week
Using proportions, the costs are given as follows:
a) Total Labor Cost: $2,505,600.
b) Total Product Cost: $1,950,000.
c) Total Cost = $4,455,600.
d) Cost per home = $461.77.
e) Cost per week = $99,013.33.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
For item a, the labor cost is found using the earnings of the workers, as follows:
45 weeks x 5 days x 8 hours x 58 per hour x (12 + 8 + 4 workers)
Hence:
Total Labor Cost = 45 x 5 x 8 x 58 x 24 = $2,505,600.
For item b, the product cost is the cost of the boards, hence:
(175 + 150 + 50 boards) x 5,200
Total Product Cost = 375 x 5,200 = $1,950,000.
For item c, the total cost is the sum of the product cost and the labor cost, hence:
Total Cost = 2,505,600 + 1,950,000 = $4,455,600.
For item d, the cost per home is found dividing the total cost by the 9,649 homes, hence:
Cost per home = 4455600/9649 = $461.77.
For item e, the cost per week is found dividing the total cost by the 45 weeks, hence:
Cost per week = 4455600/45 = $99,013.33.

The simplified form of the given expression is 4.
To solve the expression 10y + 12 - 7y - 8 - 3y,
We need to combine like terms and simplify.
Simplify the expression by combining the like terms (the terms that have the same variable and the same exponent).
We have 10y, -7y, and -3y,
Which can be combined to give us a total of 0y.
This means that the variable y has been eliminated from the expression.
Combine the constant terms (the terms that don't have a variable or that have a variable raised to the power of 0).
We have 12 and -8, which can be combined to give us 4.
So, the simplified expression is 4.
We can express this mathematically as follows:
10y + 12 - 7y - 8 - 3y = (10y - 7y - 3y) + (12 - 8)
= 0y + 4 = .

The equation of line is ax + by + c = 0.
A line's equation has the conventional form ax + by + c = 0. Here, the variables are x and y, the coefficients are a and b, and the constant term is c. It is a first-order equation with the variables x and y. The coordinates of the point on the line shown in the coordinate plane are represented by the values of x and y.
With the aid of the line's slope and a point on the line, the equation of a line may be created. For a better understanding of how a line's equation is created, let's learn more about the line's slope and the necessary point on the line. The slope of a line is the angle that the line makes with the positive x-axis and can be stated as a numerical integer, fraction, or as the tangent of that angle. The term "point" refers to a coordinate system point with the x and y coordinates.

Describe a pair of independent events and a pair of dependent events. Explain your reasoning.
Independent events are the ones whose occurrence is unrelated to any other event.
Dependent events include those that are dependent on previous events.
What is described as independent events?If the probability of an event A occurring is not impacted by the occurring of some other event B, then A & B are referred to as independent events.
Consider the example of a die roll. If A is the event 'the number appearing is odd' and B is the event 'the number showing up is a multiple of 3,'
P(A) = 3/6 = 1/2
P(B) = 2/6 = 1/3
A and B are also the events 'the number showing up is odd & a multiple of 3', implying that;
P(A ∩ B) = 1/6
P(A│B) = P(A ∩ B)/ P(B) = 1/2
Then P(A) = P(AB) = 1/2, implying that the happening of event B has had no effect on the probability of occurring of event A.
What is described as dependent events?Dependent events include those that are dependent on previous events. The outcomes of previous events have an impact on these events. Dependent events are two or maybe more events that are dependent on one another.
When two events, A and B, are interdependent, the probability of their occurrence is:
P(A and B) = P(A) · P(B|A)

In this questions we have been given the the coordinates of the triangle XYZ.
X(-5, 9), Y(2, 1), Z(-8, 3)
We need to find the measures of the sides of ΔXYZ .
We find the the measures of the sides using distance formula.
XY = √[(1 - 9)² + (2 + 5)²]
XY = √[-8² + 7²]
XY = √(64 + 49)
XY = √(113)
XY = 10.6
Now side YZ
YZ = √[(3 - 1)² + (-8 - 2)²]
YZ = √[(2)² + (-10)²]
YZ = √4 + 100
YZ = √104
YZ = 11.2
And the length of side XZ would be,
XZ = √[(3 - 9)² + (-8 + 5)²]
XZ = √(-6² + -3²)
XZ = √(36 + 9)
XZ = √45
XZ = 6.7
We find the sum of the squares of the two smaller sides, and compare the sum to the square of the largest side.
the sum of the squares of the two smaller sides is,
= 6.7² + 10.6²
= 44.89 + 115.54
= 160.43
= 12.67²
And 11.2² = 125.44
Since the sum of the squares of the two smaller sides is greater than the square of the largest side, the triangle must be an acute triangle.
Therefore, the measures of the sides of ΔXYZ are XY = 10.6, YZ = 11.2, XZ = 6.7 and the triangle XYZ must be an acute triangle

It is given that:
Sample Data
M1 = 10 M2 = 15
SS1 = 90 SS2 = 70
As we know,
The F ratio:
F = S²(x)/S²(y)
From the data given we can say:
Reduce SSwithin and boost the F-magnitude. ratio's
Thus, the decrease SSwithin and increase the size of the F-ratio be the effect of changing the value of ss1 to 50 option (D) is correct.

Answer: the circle is not a function
the square is a function
Step-by-step explanation:
In Δ J L P, m ∠J M P=3 x-6 J K=3 y-2 , and L K=5 y-8 .
Find L K if PK is a median.
In Δ JLP, m ∠ JMP = 3x - 6, JK = 3y - 2, and LK = 5y - 8 then the value of LK = 7.
What is a median?The median is the value that separates the upper and lower halves of a data sample, population, or probability distribution. It is sometimes referred to as "the middle" value in a data set.
The middle number is discovered by sorting all data points and selecting the one in the middle (or if there are two middle numbers, taking the mean of those two numbers).
Since [tex]$\overline{P K}$[/tex] is a median, JK = KL.
3y - 2 = 5y - 8
simplifying the above equation, we get
3y - 5y - 2 = 5y - 5y - 8
-2y - 2 = -8
Adding 2 on both sides of the equation
-2y - 2 + 2 = -8 + 2
-2y = -6
y = 3
Substitute the value of y in LK, then we get
LK = 5y - 8
= 5(3) - 8
= 15 - 8
LK = 7
Therefore, the value of LK = 7.

Add -4 3/8 + 8 6/7 enter your answer
Answer:
Step-by-step explanation:
first you need to make the 3/8 and 6/7 into 21/56 and 48/56 then you take the -4 and 8 then add then together you get 4 then you still have the 21/56 and 48/56 which you need to add so 48 + 21 = 69/56 or 1 and 13/56 you then add the 1 to the 4 which gives you 5 then add the 13/56 to it which gives you your answer of 5 and 13/56

An investment portfolio is shown below.
Investment Amount Invested ROR
Savings Account $2,600 1.7%
Municipal Bond $3,700 3.2%
Preferred Stock $575 12.9%
Common Stock A $1,225 −5.6%
Using technology, calculate the weighted average ROR of the investments. Round to the nearest tenth of a percent.
2.1%
3.1%
5.9%
7.5%
Based on the investment portfolio given, the weighted average ROR of the investments would be 2.1%
What is the weighted average?First, find the total portfolio value:
= 2,600 + 3,700 + 575 + 1,225
= $8,100
The weighted average Rate of Return (ROR) on the investments is:
= (2,600 / 8,100 x 1.7%) + (3,700 / 8,100 x 3.2%) + (575 / 8,100 x 12.9%) + (1,225 / 8,100 x -5.6%)
= 2.076
= 2.1%
