Kyle deposited $1200 in a savings account that earns 4.25% simple annual interest. If kyle keep the money in the account for 4 years what is the new balance?
Answer:
If kyle keeps the money in the account for 4 years, the new balance is $1,417.37.
Step-by-step explanation:
You can use the formula to calculate the future value to find the money in the account after 4 years:
FV=PV*(1+i)^n
FV= future value
PV= present value=$1,200
i= interest rate=4.25%=0.0425
n=number of periods of time=4
FV=1,200*(1+0.0425)^4
FV=1,200*(1.0425)^4
FV=1,417.37
According to this, the answer is that if kyle keeps the money in the account for 4 years, the new balance is $1,417.37.

Variance is the measurement of the spread between numbers in a given set of data.
The variance for the set is 12083.929
What is a variance?It is the measurement of the spread between numbers in a given set of data.
We have,
3, 33, 303, 233, 3, 73, 83, 63
The formula to find variance:
Find the means of the set of data.
Find the deviation of the set of data from the mean.
Find the sum of the squares of the mean deviations.
Divide the sum of the squares of the mean deviations by (n-1)
where n is the number of data in the set.
The mean:
= (3 + 33 + 303 + 233 + 3 + 73 + 83 + 63) / 8
= 794/8
= 99.25
Deviation from the mean:
3 - 99.25 = -96.25
33 - 99.25 = -66.25
303 - 99.25 = 203.75
3 - 99.24 = -96.25
73 - 99.25 = -26.25
83 - 99.25 = -16.25
63 - 99.25 = -36.25
The sum of the squares of Mean deviation:
= 9264 + 4389 + 41514 + 9264 + 689 + 264 + 1314
= 84587.5
The variance:
= 84587.5 ÷ (8 - 1)
= 84587.5 / 7
= 12083.929
Thus,
The variance for the set is 12083.929

La factura de celular del mes pasado ascendió a un total de $239 por un consumo de 269 minutos de llamada, mientras que la de este mes ascendió a $175 por un consumo de 141 minutos. El importe es la suma de una tasa fija (renta de línea) más un precio fijo por minuto. Calcular la tasa y el precio por minuto
Answer:
Costo fijo= $104.5
Costo unitario= $0.5 por minuto
Step-by-step explanation:
Mes pasado:
$239 por 269 minutos
Mes corriente:
$175 por 141 minutos
Primero debemos calcular el cost por minuto de llamada:
Costo unitario= (costo total más alto - costo total más bajo) / (cantidad de minutos más alto - cantidad de minutos más bajo)
Costo unitario= (239 - 175) / (269 - 141)
Costo unitario= $0.5 por minuto
Ahora, el costo fijo:
Costo fijo= costo total más alto - (costo unitario*cantidad de minutos más alto)
Costo fijo= 239 - (0.5*269)
Costo fijo= $104.5
Costo fijo= costo total más bajo - (costo unitario*cantidad de minutos más bajo)
Costo fijo= 175 - (0.5*141)
Costo fijo= $104.5

Answer:
y = -2/3x
Step-by-step explanation:
A perpendicular line is the negative reverse of the slope of the other line. I'm not sure about the options you have there but hopefully this helps you get your answer.
What’s the answer to the question
Answer:
Slope = -2, y-intercept = 12 (b)
Step-by-step explanation:
Using the slope formula:
slope = change in y (y2-y1) / change in x (x2-x1)
slope = (12-18)/(0+3)
slope = -6/3
slope = -2
The slope is -2
If you look in the table, when x=0, the y value equals 12. This means that the y-intercept = 12, since the y-intercept is when the x equals 0. Thus we have our answer.
Important phases of Newton's education and scientific work occurred in isolation. Why might this have been helpful to him? On the other hand, why is working in isolation problematic for developing scientific ideas?
Answer:
Step-by-step explanation:
This might have been helpful to Newton as it allowed him to focus more clearly on his ideas. Newton was incredibly talented and ahead of his time in his field, which being in isolation helped him focus and develop on his ideas. This is not the case for the majority, most scientists tend to focus on a single aspect of a problem, usually the aspect that they have the most experience in. This can lead to them being blinded and not being able to see the possible solution. That is why working with others that are able to view the problem from a different perspective can help greatly.
Working in isolation might have helped Newton focus clearly on his ideas.
Working in isolation might be problematic in developing scientific ideas because of the tendency of having a narrow perspective about a problem and not being able to find possible solution.
What is Working in Isolation?Working in isolation means to work remotely or alone without the input or help from other people.
Working in isolation might have been helpful to Newton, who was quite talented, as it may have enabled him focus clearly on his ideas.
Why Might Working in Isolation Problematic?1. Tendency of having a narrow perspective about a problem.
2. Probability of not being able to find possible solution.
In summary, working in isolation might have helped Newton focus clearly on his ideas.

What is the slope of the line that passes through (1, 4) and (-3, -3)?
Answer:
y=7/4x+9/4
Step-by-step explanation:
You want to find the equation for a line that passes through the two points:
(1,4) and (-3,-3).
First of all, remember what the equation of a line is:
y = mx+b
Where:
m is the slope, and
b is the y-intercept
First, let's find what m is, the slope of the line...
The slope of a line is a measure of how fast the line "goes up" or "goes down". A large slope means the line goes up or down really fast (a very steep line). Small slopes means the line isn't very steep. A slope of zero means the line has no steepness at all; it is perfectly horizontal.
For lines like these, the slope is always defined as "the change in y over the change in x" or, in equation form:
So what we need now are the two points you gave that the line passes through. Let's call the first point you gave, (1, 4), point #1, so the x and y numbers given will be called [tex]x_1[/tex] and [tex]y_1[/tex]. Or,
Also, let's call the second point you gave, (-3,-3), point #2, so the x and y numbers here will be called [tex]x_2[/tex] and [tex]y_2[/tex]. Or,
Now, just plug the numbers into the formula for m above, like this:
m=
[tex]\frac{-3-4}{-3-1}[/tex]
m= 7/4
So, we have the first piece to finding the equation of this line, and we can fill it into y=mx+b like this:
y=7/4x+b
Now, what about b, the y-intercept?
To find b, think about what your (x,y) points mean:
(1,4). When x of the line is 1, y of the line must be 4.
(-3,-3). When x of the line is -3, y of the line must be -3.
Because you said the line passes through each one of these two points, right?
Now, look at our line's equation so far: y=7/4x+b. b is what we want, the 7/4 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specifically passes through the two points (1,4) and (-3,-3).
So, why not plug in for x and y from one of our (x,y) points that we know the line passes through? This will allow us to solve for b for the particular line that passes through the two points you gave!.
You can use either (x,y) point you want..the answer will be the same:
(1,4). y=mx+b or 4=7/4 × 1+b, or solving for b: b=4-(7/4)(1). b=9/4.
(-3,-3). y=mx+b or -3=7/4 × -3+b, or solving for b: b=-3-(7/4)(-3). b=9/4.
See! In both cases we got the same value for b. And this completes our problem.
The equation of the line that passes through the points
(1,4) and (-3,-3)
is
y=7/4x+9/4

A gas station had two pumps. Pump A dispensed 241,752 gallons. Pump B dispensed 113,916 more gallons than Pump A. About how many gallons did both pumps dispense?
Answer:
Total gallons= 597,420
Step-by-step explanation:
Giving the following information:
Pump A dispensed 241,752 gallons.
Pump B dispensed 113,916 more gallons than Pump A.
First, we will calculate the number of gallons dispensed by Pump B:
Pump B= Pumb A + 113,916
Pump B= 241,752 + 113,916
Pump B= 355,668 gallons
