Answer: 15 degrees.
Step-by-step explanation:
A bisector divides an angle in half. So, we know the total angle of ABC is 20 degrees, as show in blue. We draw the bisector BD in the middle, meaning each side is 10 degrees, show in green. This means angle ABD is 10 degrees and angle CBD is is 10 degrees. We bisect angle CBD with BE, shown in red. This means that we have two 5 degree angles on either side, angle CBE and angle EBD. Lastly, we need to find angle ABE, highlighted in orange. We add the components, which are angle DBA, measuring 10 degrees, and angle EBD, measuring 5 degrees. When added together, this equals 15 degrees, which is our final answer for angle ABE.

the greek army contained two types of soldiers: the upper class and the lower class soldiers. if there were a total of 5 upper class soldiers, and 10 lower class soldiers in a certain part of athens, and the battle of thermopylae demands a force of 4 upper class soldiers and 8 lower class soldiers, how many different battalions can be sent?
50 different greek armies, the upper class and the lower class soldiers battalions can be sent.
The Greek army can form different battalions by choosing 4 upper class soldiers and 8 lower class soldiers from a total of 5 upper class soldiers and 10 lower class soldiers. This problem can be solved using a combination formula known as a binomial coefficient.
The number of different battalions that can be sent is:
(5 choose 4) * (10 choose 8) = 5*10 = 50
Different battalions can be formed by choosing 4 upper class soldiers and 8 lower class soldiers from a total of 5 upper class soldiers and 10 lower class soldiers. Therefore, 50 different battalions can be sent.
So, 50 different battalions can be sent.

What is the probability of flipping 4 coins on the same side, that is getting either all heads or all tails? give the exact decimal answer without rounding.
The probability of flipping four coins is 0.0625
Total coins = 4
The study of chances, which are determined by the ratio of favourable occurrences to probable cases, is known as probability.
When flipping a coin, there are two possible outcomes (heads or tails), hence the likelihood of flipping a head-up coin is equal to the likelihood of flipping a tail-up coin.
Thus, the probability is = 1/2
Calculating the probability of getting all heads or all tails when flipping 4 coins -
= 1/2 x 1/2 x 1/2 x 1/2
= 1/16

The simple interest rate that you are charged, based on the loan amount and the period of the loan, is 3. 5 %
How to find the simple interest rate ?Borrowers must pay lenders simple interest as a fee in exchange for a loan. Compound interest is excluded from the calculation and just the original principal is used. Simple interest applies to all loans, not just specific ones. Additionally, it refers to the kind of interest that banks give their customers on their savings accounts.
Simple interest is the amount of interest charged on a specific principal amount at a specific interest rate. Compound interest, on the other hand, is the interest that is computed using both the principal and the interest that has accumulated over the preceding period.
To find the simple interest rate, find the simple interest charged per year to be:
= 175 / 2

O Statistic as it represents the sample
O Statistic as it represents the population
Answer:
Step-by-step explanation:
O Statistic as it represents the sample
The number 2.5 is considered a statistic because it is calculated from a sample of second graders in a school district. This number is an estimate of the average number of pets that all second graders in the school district have, but it is not the exact number, as the sample may not be fully representative of the population. A parameter, in contrast, is a fixed value that represents a characteristic of a population, such as the population mean or population proportion. Since the number 2.5 is an estimate calculated from a sample and not the exact value of the population, it is considered a statistic.

The number of non-similar 1000-pointed stars is
[tex]$\frac{1000-600-2}{2}= \boxed{199}.$[/tex]
If we join the adjacent vertices of the regular [tex]$n$[/tex]-star, we get a regular [tex]$n$[/tex][tex]-gon[/tex]. We number the vertices of this [tex]$n$[/tex][tex]-gon[/tex] in a counter clockwise direction: [tex]$0, 1, 2, 3, \ldots, n-1.$[/tex]
A regular [tex]$n$[/tex]-star will be formed if we choose a vertex number m where [tex]$0 \le m \le n-1$[/tex], and then form the line segments by joining the following pairs of vertex numbers:[tex]$(0 \mod{n}, m \mod{n}),$ $(m \mod{n}, 2m \mod{n}),$ $(2m \mod{n}, 3m \mod{n}),$ $\dots,$ $((n-2)m \mod{n}, (n-1)m \mod{n}),$ $((n-1)m \mod{n}, 0 \mod{n}).$[/tex]
If [tex]$\gcd(m,n) > 1$[/tex], then the star degenerates into a regular [tex]$\frac{n}{\gcd(m,n)}$-gon[/tex] or a (2-vertex) line segment if [tex]$\frac{n}{\gcd(m,n)}= 2$[/tex]. Therefore, we need to find all $m$ such that [tex]$\gcd(m,n) = 1$.[/tex]
Note that [tex]$n = 1000 = 2^{3}5^{3}.$[/tex]
[tex]Let $S = \{1,2,3,\ldots, 1000\}$, and $A_{i}= \{i \in S \mid i\, \textrm{ divides }\,1000\}$. The number of $m$'s that are not relatively prime to $1000$ is: $\mid A_{2}\cup A_{5}\mid = \mid A_{2}\mid+\mid A_{5}\mid-\mid A_{2}\cap A_{5}\mid$ $= \left\lfloor \frac{1000}{2}\right\rfloor+\left\lfloor \frac{1000}{5}\right\rfloor-\left\lfloor \frac{1000}{2 \cdot 5}\right\rfloor$ $= 500+200-100 = 600.$[/tex]
[tex]Vertex numbers $1$ and $n-1=999$ must be excluded as values for $m$ since otherwise a regular n-gon, instead of an n-star, is formed.[/tex]
The cases of a 1st line segment of (0, m) and (0, n-m) give the same star. Therefore we should halve the count to get non-similar stars.
Therefore, the number of non-similar 1000-pointed stars is
[tex]$\frac{1000-600-2}{2}= \boxed{199}.$[/tex]
[tex]Note that in general, the number of $n$-pointed stars is given by $\frac{\phi(n)}{2} - 1$ (dividing by $2$ to remove the reflectional symmetry, subtracting $1$ to get rid of the $1$-step case), where $\phi(n)$ is the Euler's totient function.[/tex] [tex]It is well-known that $\phi(n) = n\left(1-\frac{1}{p_1}\right)\left(1-\frac{1}{p_2}\right)\cdots \left(1-\frac{1}{p_n}\right)$, where $p_1,\,p_2,\ldots,\,p_n$ are the distinct prime factors of $n$.[/tex] [tex]Thus $\phi(1000) = 1000\left(1 - \frac 12\right)\left(1 - \frac 15\right) = 400$, and the answer is $\frac{400}{2} - 1 = 199$.[/tex]

A rental car company charge $75 for a 3-day rental and $155 for a 7-day rental. Write an
equation to find the amount that the rental car company will charge for any number of day
The equation to find the amount the rental car company will charge for any number of days is y = 75+20(n-3).
Mathematically, an equation can be defined as a statement that supports the equality of two expressions, which are connected by the equals sign “=”.
Given that,
The charge per day for a 3-day rental = 75/3 = 25
The additional charge for an extra 4 days is (155-75)= 80 which is $20 per day.
The charge for a period of n days (n>3) is then 75+20(n-3).
Thus, The equation to find the amount the rental car company will charge for any number of days is y = 75+20(n-3).

1) The function f(x) is defined as follows: B. F(x) = -(x + 2)²(x - 2).
2) The standard definition of function f(x) is given as follows: A. F(x) = ax³ + bx² + cx + d.
4. The solution to the system of equations is approximated by the following option:
A. (-3.43, 6.30).
How to define the functions?The function for item 1 is defined considering it's roots, as follows:
x = -2, with a multiplicity of 2, as the function just touches the x-axis, not crossing.x = 2, with a multiplicity of 1.Hence the function is defined as follows:
F(x) = a(x + 2)²(x - 2).
The y-intercept is positive, meaning that:
-8a > 0.
Thus the leading coefficient a is negative, and the correct option is given by option B.
The cube function, with all positive coefficients, is given by option A in item 2.
How to solve a system of equations graphically?The graphic solution of a system of equations is given by the point of intersection of all the equations that compose the system.
The equations that compose the system in this problem are given as follows:
v(x) = x³ + 2x² - 5x + 6.b(x) = -3x - 4.For this problem, the systems are composed by a third degree function v(x) and a linear function b(x), hence we graph them and obtain the point of intersection.
