Answer: Alright get ready for a long explanation
he would have 820.00$ in his savings account after the 5 years
Step-by-step explanation:
if he earns 12% interest then you would have to multiply 100 by the 12/100 which is .12 in decimal form.
100 TIMES .12 = $12.00
because we are doing this in months you need to multiply the amount he makes per month by the amount of months that the 100 dollars is in the bank account.
Alright so now that thats over, he makes 12 dollars every month
thers 12 months in a year, so you would have to do 12 (the number of moths) times 5 (the amount of years) that equals 60.
60 TIMES the amount he makes per month ($12) equals $720.00
LASTLY! add the amount he made to the original amount and you get the answer of $820.00
i hope this helps :)
By visual inspection, determine the best-fitting regression model for the data plot below.
A) Exponential
B) No pattern
C) Linear decreasing
D) Linear increasing
Answer:
A) exponential
Step-by-step explanation:
It is in a curving pattern which indicates exponential. Linear is a straight line.
The best-fitting regression model for the considered data plot is given by: Option A: Exponential.
What is fitting of curve for a data plot?When the data shows some trend, either linear (making a line), or non-linear (a predictable curve), we fit a mathematical curve on that data set, as a representative of the pattern in that data set, to predict the output based on the inputs.
The considered plot is not forming a straight line(so no linear fitting), but we can see that a smooth curve can be fitted in the considered data. Since the exponential functions' graph approximately goes the same way (for positive exponent, and increasing value of output).
Thus, the best-fitting regression model for the considered data plot is given by: Option A: Exponential.

Answer:
radius = 16 inches
C = 32pi or approximately 100.48 inches
Step-by-step explanation:
We know the diameter is twice the radius
d = 2r
32 = 2r
Divide each side by 2
32/2 =2r/2
16 =r
The radius is 16 inches
The circumference is equal to
C = pi * diameter
C = pi *32
C = 32 pi inches
Letting pi be approximated by 3.14
The circumference is approximately 100.48 in
The radius is 16 inches.
This is because the radius is half the diameter and since we know that the diameter is 32 inches you just have to divide it by 2.
The circumference is 32 pi
This is because the circumference is 2 times pi times radius. This means that is is diameter times pi. This is because we know that that 2 times the radius is equal to the diameter.

What is the range in miles for the different ways that Bryan traveled?
FOUND ANSWER: 31
Answer:
[tex]\boxed{\text{[2, 33]}}[/tex]
Step-by-step explanation:
The range is the spread of the y-values (minimum to maximum distance travelled).
The minimum is 2 mi, and the maximum is 33 mi, so the range is from 2 to 33.
In interval notation, the range is [tex]\boxed{\textbf{[2, 33]}}[/tex]
Answer:
31
Step-by-step explanation:
31
The range is the difference between the largest and smallest number.
range = biggest − smallest = 33 − 2 = 31

Enrollment in French class at a high school is 0.72 of enrollment in Spanish class. What is enrollment in French class compared to Spanish class as a fraction and as a percent?
Final answer:
The enrollment in the French class compared to the Spanish class is 18/25 as a fraction and 72% as a percent.
Explanation:
To find the enrollment in the French class compared to the Spanish class as a fraction, we need to use the information given that enrollment in French class is 0.72 of enrollment in Spanish class. This means that for every 1 student in the Spanish class, there are 0.72 students in the French class.
To represent this as a fraction, we can write it as 0.72/1 or simply 72/100. Simplifying this fraction gives us 18/25.
To find the enrollment in the French class compared to the Spanish class as a percent, we can convert the fraction 18/25 to a percent. To do this, we divide 18 by 25 and multiply by 100. This gives us 72%.

Given:
OH
⊥
BC
, OB=10,
OH=6, EF=9, AB=2
Find: AE.
Answer:
AE=3
Step-by-step explanation:
1. Consider right triangle BOh. In this triangle, OB=10 (hypotenuse), OH=6 (leg), then by the Pythagorean theorem,
[tex]BH^2=BO^2-OH^2\\ \\BH^2=10^2-6^2\\ \\BH^2=100-36\\ \\BH^2=64\\ \\BH=8.[/tex]
2. Since OH⊥BC, then BC=2BH=16.
3. Use the secants property: If two secant segments are drawn to a circle from the same external point, the product of the length of one secant segment and its external part is equal to the product of the length of the other secant segment and its external part.
Thus,
[tex]AE\cdot FA=AB\cdot AC.[/tex]
So,
[tex]AE\cdot (AE+9)=2\cdot (2+16)\\ \\AE(AE+9)=36\\ \\AE^2+9AE-36=0\\ \\D=9^2-4\cdot (-36)=81+144=225\\ \\AE_{1,2}=\dfrac{-9\pm\sqrt{225}}{2}=-12,\ 3.[/tex]
The segment cannot be of negative length, therefore, AE=3.
Intersecting Secant Theorem helps to establish the relation between two secants of a circle. The length of the side AE will be equal to 3 units.
What is Intersecting Secant Theorem?When two line secants of a circle intersect each other outside the circle, the circle divides the secants into two segments such that the product of the outside segment and the length of the secant are equal to the product of the outside segment and the other secant's length.
a(a+b)=c(c+d)
If we look into the triangle BOH, then the length of the side BH using the Pythagoras theorem can be written as,
[tex]OB^2=OH^2+BH^2\\\\10^2 = 6^2 + BH^2\\\\BH= 8\rm\ units[/tex]
Now, the length of BC will be twice the length of BH, therefore, the length of the line BC can be written as,
[tex]\text{Length of BC} = 2 \times (\text{Length of BH})\\\\\text{Length of BC} = 2 \times 8 = 16\rm\ units[/tex]
Now, using the Intersecting secant theorem the length of AE can be written as,
[tex](AB \times AC) = (AE \times FA)\\\\2(2+16) = AE(AE+9)\\\\36=AE^2+9AE\\\\AE^2+9AE-36 = 0\\\\AE^2+12 AE - 3AE -36=0\\\\AE(AE+12)-3(AE+12)=0\\\\(AE-3)(AE+12)=0\\\\AE = 3, -12[/tex]
Since the length can not be negative, therefore, the length of the side AE will be equal to 3 units.

Which graphical display is best used to organize numerical data in ascending order?
scatter plot
line graph
box-and-whisker plot
stem-and-leaf plot
Answer:
line graph
Step-by-step explanation:
Line graphs easily help the visual learner to interpret data and understand peaks and decreases in certain levels. It connects data points and allows people to see what is actually going on.
Answer:
line graph
Step-by-step explanation:
The explanations of each plot are:
Scatter plot
It is used to see the correlation between two variables. The correlation can be positive (increases), negative (decreases) or zero (no correlation at all). This plot can be used to draw a trend line to study the correlation between variables using an equation, generally a line and which prosses is call line regression.
Line graph
Is like the scatter plot but instead of leaving the data or points without connection the line graph connects the points, representing the data, with a line, so to easily show a tendency between variables, which generally tends to increase.
This plot is an easy way to show a tendency, but the scatter plot can give more statistical information about a correlation between variables.
box-and-whisker plot
Shows the median and the quartiles of the data, i.e. shows a interval in which the recollected data can be found and its frequency of repetition.
stem-and-leaf plot
Allows to simultaneously see the frequency distribution of the variable and its graphic representation and its constructed by separating, in each data, the last digit of the right (the leaf) to the remaining digits (the Stem).
So, to easily show numerical data in ascending order it can be used the line graph, but it can be used de scatter plot to give deeper statistical information too.
