Step-by-step explanation:
The Osborne 1 is the first commercially successful portable microcomputer, released on April 3, 1981 by Osborne Computer Corporation. It weighs 10.7 kg (24.5 lb), cost US$1,795, and runs the CP/M 2.2 operating system
The approximate weight of a laptop in 2019 is 1.76 kg
The correct answer is an option (d)
What is percent?"It is a number can be expressed as a fraction of 100."
What is the formula for exponential decay?" [tex]f(t)=a(1-r)^t[/tex] where a is the initial value,
r is the rate of decay
and t is the time period."
For given question,
The initial weight of the laptop in 1981 (a) = 11 kg
The mass of laptops has decreased at an average rate of 4.7%
We can write above percentage as,
[tex]4.7\%\\=\frac{4.7}{100}\\ =0.047[/tex]
So, the rate of r = 0.047
We need to find the approximate weight of a laptop in 2019.
So the time period would be,
⇒ t = 2019 - 1981
⇒ t = 38
Using exponential decay formula,
[tex]\Rightarrow f(38)=11\times(1-0.047)^{38}\\\\\Rightarrow f(38)=11\times (0.953)^{38}\\\\\Rightarrow f(38)=1.76[/tex]
Therefore, the approximate weight of a laptop in 2019 is 1.76 kg
The correct answer is an option (d)

What is an equation of the line that passes through the points (4,-5) and (-2,7)
Answer:
y = -2x + 3
Step-by-step explanation:
y2 - y1/ x2 - x1
7 - (-5) / -2 - 4
-2
The slope is -2.
To find the y-intercept, you need to plug the coordinates into the equation.
y = -2x + b
7 = -2(-2) + b
7 = 4 + b
3 = b
y = -2x + 3
Answer:
y=-2x+3
Step-by-step explanation:
To find the equation of the line passing through the points (4, -5) and (-2, 7), we can use the point-slope form of the equation of a line:
y - y₁ = m(x - x₁)
where (x₁, y₁) represents one of the given points, and m is the slope of the line.
Let's calculate the slope (m) using the formula:
m = (y₂ - y₁) / (x₂ - x₁)
Substituting the coordinates of the points (4, -5) and (-2, 7) into the formula:
m = (7 - (-5)) / (-2 - 4)
m = 12 / -6
m = -2
Now we have the slope (m = -2), and we can choose one of the given points (4, -5) to substitute into the point-slope form. Let's use (4, -5):
y - (-5) = -2(x - 4)
Simplifying:
y + 5 = -2(x - 4)
y + 5 = -2x + 8
y = -2x + 3
Find the unit rate.
$220 for 17 ft
Answer:
$12.94 per foot
Step-by-step explanation:
Find the unit rate by dividing the cost by the number of feet
220/17
= 12.94
So, the unit rate is approximately $12.94 per foot

Solve this system using substitution: y=5x and 7x-3y=32
Solve equation [2] for the variable y
[2] 2y = -5x + 1
[2] y = -5x/2 + 1/2
// Plug this in for variable y in equation [1]
[1] 7x - 3•(-5x/2+1/2) = -5
[1] 29x/2 = -7/2
[1] 29x = -7
// Solve equation [1] for the variable x
[1] 29x = - 7
[1] x = - 7/29
// By now we know this much :
x = -7/29
y = -5x/2+1/2
// Use the x value to solve for y
y = -(5/2)(-7/29)+1/2 = 32/29
Solution :
{x,y} = {-7/29,32/29}

Does lower limit includes the numbers in a class interval or a upper limit?
Answer:
No, it doesn't include them.
Step-by-step explanation:
In statistics intervals, the lower limit is the least value in the class limit while the upper limit is the highest value in the class interval.
For example, an interval of a class limit of 20 - 30,the lower limit is 20 while the upper limit is 30.
Thus,the lower limit doesn't include the numbers in the interval or the upper limit.

Answer:
[tex] \huge \color{purple}{answer}[/tex]
To draw a circle whose radius is given, we require a ruler and compasses. Given that the radius is 5 cm, the steps to be followed are:
Step 1: Place the pointer of the compass at the initial point of the ruler (0 cm) and extend the other end of the pencil measuring 5 cm from the initial point (i.e. 5 cm)
Step 2: Mark a point O on a piece of paper. This point is supposed to be the center of the circle that you are about to construct.
Step 3: Place the pointer of the compass at point 0.
Step 4: Turn the compass slowly through 360 degrees to draw a circle.
[tex] \small\color{pink}{point \: to \: remember}[/tex]Make sure that you hold the point of the compass stiffly on the paper. You are also required to move the compass through the 360 degrees in one go for accuracy and neatness.
A circle is a locus of all points in 2 dimensional space which are equidistant from some fixed point. The constructed circle with radius 5 units is constructed below.
How to construct a circle with specific radius?We need two tools. first is ruler, and second is compass.
Take some fixed point on a paper. Let it be called OTake the ruler and draw an 'r' unit sized line segment OA.Use the compass, place its pointy tip on the fixed point O and the pen or pencil of compass on the second endpoint A of the constructed line segment.Now make a full rotation of the compass so that a ring like figure is created.This is the needed circle.
One such circle (radius of 5 units) is constructed is attached below.

Lindsey purchased a random sample of 25 tomatoes at the farmers market. The 95% confidence interval
for the mean weight of the tomatoes is 90.6 to 112.4 grams.
What is the Point Estimate?
What is the Margin of error?
Answer:
3 & 5
Step-by-step explanation:
The value of point estimate is 101.5 and value of margin of error is 10.9 gram if the Lindsey purchased a random sample of 25 tomatoes at the farmers market.
What is the margin of error(MOE)?It is defined as an error that provides an estimate of the percentage of errors in real statistical data.
The formula for finding the MOE:
[tex]\rm MOE = Z\times \dfrac{s}{\sqrt{n}}[/tex]
Where Z is the z-score at the confidence interval
s is the standard deviation
n is the number of samples.
Let's suppose m is a point estimate and ME is the margin of error.
The structure of the confidence interval is:
(m—ME, m + ME)
The given confidence interval is (90.6, 112.4)
Then, m—ME = 90.6 ..... (1)
m + ME = 112.4 ..... (2)
After solving equation (1) and (2) we get:
m = 101.5
ME = 10.9 grams
Thus, the value of point estimate is 101.5 and value of margin of error is 10.9 gram if the Lindsey purchased a random sample of 25 tomatoes at the farmers market.

Answer:
5.1
Step-by-step explanation:
thats what i got on savvas hope this helps!
The distance between the points S(2.3,4.8) and T(6.4,7.9) is 5.14 units.
What is distance between the points?Distance between two points is the length of the line segment that connects the two points in a plane.
Given that, two points S(2.3,4.8) and T(6.4,7.9), we need to find the distance between them,
The distance between the two points =
D = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Here, (x₁, y₁) and (x₂, y₂) are S(2.3,4.8) and T(6.4,7.9)
So,
D = [tex]\sqrt{(6.4-2.3)^2+(7.9-4.8)^2}[/tex]
= [tex]\sqrt{(4.1)^2+(3.1)^2}[/tex]
= [tex]\sqrt{26.42[/tex]
= 5.14
Hence, the distance between the points S(2.3,4.8) and T(6.4,7.9) is 5.14 units.
