Compound Interest Equation
A = P(1 + r/n)nt
Where:
A = Accrued Amount (principal + interest)
P = Principal Amount
I = Interest Amount
R = Annual Nominal Interest Rate in percent
r = Annual Nominal Interest Rate as a decimal
r = R/100
t = Time Involved in years, 0.5 years is calculated as 6 months, etc.
n = number of compounding periods per unit t; at the END of each period
If AB = CA and m1 = 45°, what is m3?
A.
47°
B.
45°
C.
43°
D.
90°
Answer:
B 45 degrees
Step-by-step explanation:
if AB and CA are = the M2 = 90 degrees
in an right triangle ware one angle is 90 degrees and one is 45 degrees the outer one will be 45 degrees
the total of the angles in a triangle is 180 degrees so 180 - 90 = 90
90 - 45 = 45
so the remaining angle is 45.

O.C. g(x) = 1x1 + 5
D. g(x) = (x + 51
Answer: i thini its 2
Step-by-step explanation:
The function g(x) is:
g(x) = Ix - 5I.
Therefore, the option A in the given question is correct.
What is transformation on the graphs?When a function is transformed, the graph's curve either "moves to the left, right, up, or down," "expands or compresses," "reflects," or all three.
The function is made possible by the fundamental function f(x) and the constant
g(x) = f(x - k),
horizontally moving, the f(x) k unit coordinates may be drawn.
The shift's direction depends on the value of k. Specifically,
If k > 0, the basis graph shifts right by k units.
If k < 0, the base graph shifts k units to the left.
Given that the parent function is f(x) = IxI.
From the definition,
the transformed function is moved horizontally to 5 units to the right.
So, the function is g(x) = Ix - 5I.
Therefore, g(x) = Ix - 5I.

Largest value for a/b = 3/5.
n is an integer and -2
Write down the possible values of n,
from smallest to largest.
Answer:
Step-by-step explanation:
-2 < n+3 ≤ 4
Make two separate equations,
-2 < n+3
Subtract 3 from both sides,
-2-3 < n + 3 -3
-5 < n
So, value of n should be greater than (-5)
n +3 ≤ 4
Subtract 3 from both sides
n ≤ 1
So, n value should be less than or equal to 1
So, n value should be greater than -5 and less than or equal to 1
n= { -4, -3 , -2 , -1 ,0 ,1 }

[tex]= \sqrt{4a^2+4b^2}= 2\sqrt{a^2+b^2}[/tex]
Step-by-step explanation:
From the figure attached,
ΔMON is a right triangle and coordinates of the points M and N are M(0, 2b) and N(2a, 0).
Coordinates of midpoint P → [tex](\frac{2a+0}{2}, \frac{0+2b}{2})[/tex]
From the formula of the distance between two points,
[tex]d = \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}[/tex]
[tex]\texttt {MN} = \sqrt{(2a-0)^2+(0-2b)^2}\\\\ = \sqrt{4a^2+4b^2}\\\\ = 2\sqrt{a^2+b^2}[/tex]
Similarly, OP
[tex]= \sqrt{(0-a)^2+(0-b)^2}\\\\ = \sqrt{a^2+b^2}[/tex]
Therefore, OP
[tex]= \frac{1}{2}(MN)[/tex]
and MN
[tex]= \sqrt{4a^2+4b^2}= 2\sqrt{a^2+b^2}[/tex]

Answer:
62○
Step-by-step explanation:
To find the angle all you have to do is subtract 118○ from 180○ to get 62○. Because 180○ is a straight line! :)
Answer:
X = 62
Step-by-step explanation
To start we make x go next to 118 so they make a supplementary angle. We add x and 118 to make 180.
118 + X = 180, OR 180 - 118 = x
X = 62
Which represents continuous data? A) The number of times you flip a coin B) The number of students in a classroom C) The number of chocolate candies in a box D) The price of fish per pound
Answer:
D) The price of fish per pound
Step-by-step explanation:
A continuous data is one which can take any value . it can have even value between any two consecutive number.
Example :
continuous data can have value between 4 and 5 like 4.5 4.001 and so on.
Discrete data is one which can be counted such as number of flowers, no of cars in parking.
it can take value such as 1,2, 12, 66 etc.
____________________________________________
Let go through the option
A) The number of times you flip a coin
We can count the number of times a coin is flipped .
Like 2 times, 3 times and hence it is discrete data and not a continuous one.
B) The number of students in a classroom
Student in a classroom can also be counted.
in a class there can be 12, 50, 66 etc students not 12.1 , 50.5 etc.
hence it is discrete data and not a continuous one.
C) The number of chocolate candies in a box
Again, chocolate number can be counted .
Number of chocolate can be 2, 4, 5 and not 2.1 , 4.6 etc and
hence it is discrete data and not a continuous one.
D>The price of fish per pound
Price of fist cannot be counted . Further, price of fish can be $2.5 , $ 4.555
hence it is a continuous data.
Based on above discussion
continuous data is represented by The price of fish per pound
enter the mean of the data 9,5,7,7,12
Phone company A conducted a study that showed 97% customer satisfaction, with a standard deviation of 1%. The sample included 25 people who appear in one of their commercials during the past three years
phone company B conducted a study to show 94% customer satisfaction with a standard deviation of 4% a random sample consisting of 100 customers
which of the company claims is more believable and why? 
A.Phone Company A because the time span was longer
B. Phone company B bc the sample was not biased
C. Company A bc the standard deviation is smaller
D.Company B because the standard deviation is larger
Answer:
B. Phone company B because the sample was not biased.
Step-by-step explanation:
While Phone company A had a higher satisfaction rate, 25 people that conducted this poll were in at least 1 commerical of the phone company's in the past 3 years. This means that their reflection of the company is biased (typically higher) and not completely based off of their performance but instead how cool it was to be in a commerical or how much they were paid. If the poll was a more random sample of just customers, it would be more believable data. On the other hand, while phone company B had a lower satisfaction rate and higher deviation, their statistics are more believable due to the random sampling of customers.

If you diluted 300 mL of 8% benzocaine lotion to 5% how much could you produce
Answer:
you are diluting it 8/5 times, or 1.6 times.
You could make 230*1.6 ml of 5 percent lotion.
If you diluted 300 mL of 8% benzocaine lotion to 5%, you will be able to produce 480 ml of 5% lotion.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
The amount of benzocaine in 300 ml solution is,
Amount = 0.08 × 300 = 24ml
Since after the dilution the amount of benzocaine will be the same, therefore, we can write,
0.05 of X ml = 24 ml
X = 24/0.05
X = 480 ml
Hence, If you diluted 300 mL of 8% benzocaine lotion to 5%, you will be able to produce 480 ml of 5% lotion.

Use the method of substitution to solve the system of equations. please show your work! y=534x y=74.80x+1,419 Thank you so much! If you could also solve it graphically that would be best but if not thats okay!
Answer:
( 3, 1650 ), Where x = 3, and y = 1650 -
Approximately
Step-by-step explanation:
Take a look at the procedure below;
[tex]y = 534x,\\y = 74.80x + 1,419\\\\y = 534x,\\y - 74.8x = 1,419\\\\( 534x ) - 74.8x = 1,419\\459.2x = 1,419\\x = ( About ) 3\\\\y = 534 * ( x ),\\y = 534 * ( 3.1 ),\\y = ( About ) 1650[/tex]
We first converted the second equation into standard form, by subtracting 74.8x on either side. Afterwards we substituted 534x in replacement of y in this second equation, and solved for x. Knowing the value of x, it was substituted back into the first equation to solve for the value of y. Hence, the resulting solution is ( 3, 1650 ) - approximately.

A painter is painting a rectangular wall that measures 22.8 ft by 17.3 ft. Each gallon can of paint covers 100 square feet. What are the fewest gallons needed to paint the wall?
____gallons
Answer:
1.548 gallons
Step-by-step explanation:
Length of the rectangular wall = 25.1 ft.
Width of the rectangular wall = 18.5 ft.
Area of the rectangular wall = length * width = 25.1 * 18.5
= 464.35 square feet
300 square feet wall can be painted using 1 gallon of paint.
=> 1 square feet wall can be painted using gallon of paint.
=> 464.35 square feet wall can be painted using gallon of paint.
= 1.548 gallons of paint
Answer:
4 gallons
Step-by-step explanation:
The first thing you want to do is times 22.8 * 17.3 = 394.44. Then what you want to do is see how much 100 square gallons can cover the area : 4. If we make it 3 it is going under if it is 4 it can cover the whole thing, and if we make it 5 we have a little much.
In numb3rs, they use math to solve crimes. One of the ways they use Math is to reveal patterns. What is the pattern in this sequence? What would be the first and last numbers be? (6, 14, 30, 62, 126)
Step-by-step explanation:
I think the first number is 2
Then 2 x 2 = 4 so there is a difference of 4 number
Then in between 6 and 14 there is a difference of 8 so 4 x 2 = 8
Then 16 so 8 x 2 = 16
So after 126 the number is 254
SOMEONE PLEASE HELP ASAP! Normal distribution models what type of variable? A.discrete random variable B.random variable C.discrete continuous variable D.random continuous variable
A normal distribution has its center at the mean and its spread is determined by the standard deviation. For the standard normal distribution, its mean is 0 and standard deviation is 1. It is in the shape of a bell curve. Most of the values fall in or around 0, forming the peak around this area. As you move away from 0, the values are less frequent which explains the drop-off. The distribution is continuous as you can have any real number (decimal or whole). It's also random because of the nature of statistics.
