This is an order of operations problem. II'll use using PEMDAS here:
P: Evaluate expressions in parenthesis firstE: Evaluate terms with exponentsMD: Evaluate multiplication and division from left to rightAS: Evaluate addition and subtraction from left to rightParenthesis first. The first expression in parenthesis is already as simplified as it gets, so up next is the second one:
\(3\times5-3\)
There are no parenthesis and there are no exponents, so do the multiplication first.
\(\rightarrow 3\times5-3\\\rightarrow 15-3\\\rightarrow 12\)
Back to the original expression and we now have:
\((\frac{1}{2})^2\times(12)+1^3\)
Exponents comes next:
\(\rightarrow (\frac{1}{2})^2=\frac{1^2}{2^2}=\frac{1}{4}\\\\\rightarrow 1^3=1\)
Now we have:
\(\frac{1}{4}\times12+1\)
Multiplication comes next:

Enseñanza Básica is the term used to describe the first level of education in the Chilean education system, which includes the first to eighth grades. A teacher of Enseñanza Básica asked his students to choose three-digit mixed numbers that can be formed.
A mixed number is a number that has both a whole number and a fraction component. To form three-digit mixed numbers, we need to have a whole number that is less than 100 and a proper fraction that has a denominator less than or equal to 99. Here are some examples:123 4/567 2/8109 1/2382 3/47There are a total of 900 three-digit numbers that can be formed using digits 1 to 9 without repetition. To find the number of three-digit mixed numbers that can be formed, we need to count the number of ways we can choose a proper fraction with a denominator less than or equal to 99. There are 99 possible denominators, and for each denominator, there are 98 possible numerators (excluding 0 and the denominator itself). Therefore, the total number of three-digit mixed numbers that can be formed is:900 x 99 x 98 = 8,334,600There are 8,334,600 three-digit mixed numbers that can be formed using digits 1 to 9 without repetition.For such more question on fraction

mEB 163° and mBD = 77°.
What is m∠BCD?
Answers
Therefore, m angles for BCD is 98.5°.
Describe angle?
An angle is formed when two straight lines or rays meet at a single terminal. The vertex of an angle is the location where two points converge. The Latin word "angelus," which means "corner," is where the term "angle" originates.
These two theorems allow us to calculate the angle BCD's measure as follows:
To establish the angle ECB's measure first, apply Theorem 1:
m ∠ECB = m ∠DBC = 77°
Next, we can use theorem 2 to find the measure of the arc ED:
m(arc ED) = 1/2 (m∠EBD + m∠ECD) = 1/2 (163° + m∠ECB)
Since arc ED is an exterior arc to angle BCD, we can find the measure of angle BCD as:
m ∠BCD = 1/2 (m(arc BD) + m(arc ED)) = 1/2 (77° + m(arc ED))
Substituting the value we found for m(arc ED), we get:
m ∠BCD = 1/2 (77° + 1/2 (163° + m ∠ECB))
Now, we can substitute the value we found for m ∠ECB to get:
m ∠BCD = 1/2 (77° + 1/2 (163° + 77°)) = 1/2 (77° + 120°) = 98.5°

This article says short sleepers (fewer than 6 hours) are four times more likely to catch a cold than longer sleepers (over 7 hours). The article says "The researchers then sequestered 164 volunteers in a hotel, administered the cold virus via nasal drops and monitored them for a week." Without further info, what is potentially misleading?
Answers
The use of volunteer sampling means that the result of the survey is potentially misleading.
What is volunteer sampling?Volunteer sampling is a sampling technique in which each participant in the sample opts to join the research, as is the case for this problem, as each participant opted to join in the project to compare their cold lengths.
The drawback of this type of sampling is that it should contain lots of participants that share similar characteristics, such as desiring to weight/diet, and this may influence their recovery to cold. The participants also may lie, which can cause misleading results to the study.
Options to remove misleading conclusions is to use a different type of sampling, such as stratified sampling, as groups of people that are either short or long sleepers are compared to reach a conclusion.

when its comes to interest,most CDs will allow which of the following options?
a. Unlimited withdraws of interest
b. Periodic interest payout
c. loans against principal
d. Withdrawal of principal
Answers
When it comes to interest, most Certificates of Deposit (CDs) will allow periodic interest payouts. So, correct option is B.
A CD is a type of savings account that allows you to earn a fixed interest rate on your deposit for a specific period of time, called the term. Typically, the longer the term of the CD, the higher the interest rate offered.
However, during the term of the CD, the funds are locked in, meaning that you cannot withdraw the principal without incurring a penalty.
While some CDs may allow for unlimited withdrawals of interest, this is not common, and may still come with restrictions or penalties. Loans against principal are also not typically allowed with CDs, as the funds are meant to be held for a set term.
Therefore, the most common option available for CD holders is to receive periodic interest payouts, which can be monthly, quarterly, or annually, depending on the terms of the CD. This allows the CD holder to earn interest on their deposit while still receiving some income during the term of the CD.
So, correct option is B.

Answers
Based on the Pythagorean theorem, in a right triangle, the sum of the squares of the two shorter sides is equal to the square of the longest side. So, we can use this to find the possible values of the third side of the triangle.
The two given sides are 15 cm and 17 cm. We can label the unknown side as "x". Then, we can set up an equation:
15^2 + 17^2 = x^2
Simplifying this equation, we get:
225 + 289 = x^2
514 = x^2
x = sqrt(514)
Therefore, the possible value of the third side that would make it a right triangle is approximately 22.72 cm.

\(y = -(x+2)^2-3\)
Required
All possible transformations
First, the parent function is reflected across the x-axis:
This gives:
\(y = x^2\) \(==>\) \(y =-x^2\)
Next, it is translated horizontally right by 2
The rule is:
\((x,y)==>(x+2,y)\)
So:
\(y =-x^2\) \(==>\) \(y = -(x +2)^2\)
Lastly: it is translated vertically down by 3
The rule is:
\((x,y)==>(x,y-3)\)
So:
\(y = -(x +2)^2\) \(==>\) \(y = -(x +2)^2 - 3\)

Let x=11 correspond to the year 2011 and estimate the CPI in 2013 and 2014. Assume that the data can be modeled by a straight line and that the trend continues indefinitely. Use two data points to find such a line and then estimate the requested quantities. Let y represent the CPI. The linear equation that best models the CPI is____ (Simplify your answer. Use integers or decimals for any numbers in the equation. Round to the nearest hundredth as needed.)
Answers
The first thing we have to identify in our problem are the variables
\(\begin{gathered} x\to\text{time} \\ y\to\text{CPI} \end{gathered}\)Now we see the points (x,y) that gives us the problem
\(\begin{gathered} 2011\to(11,202.9) \\ 2016\to(16,233.2) \end{gathered}\)Since behavior can be modeled by a straight line, we use the general equation of the straight line
\(y=mx+b\)Where m is the slope of the line and b is the y-intercept.
Taking this into account and with the 2 points that they give us, we proceed to calculate the equation of the line starting with the slope:
\(\begin{gathered} m=\frac{y_2-y_1}{x_2-x_1} \\ m=\frac{233.2-202.9}{16-11} \\ m=\frac{30.3}{5} \\ m=6.06 \end{gathered}\)\(\begin{gathered} y=6.06x+b \\ 202.9=6.06(11)+b \\ b=202.9-66.66 \\ b=136.24 \end{gathered}\)The equation that models the behavior of the CPI is
\(y=6.06x+136.24\)Now we calculate the CPI values for the years 2013 and 2014
\(\begin{gathered} 2013\to x=13 \\ y=6.06(13)+136.24 \\ y=78.78+136.24 \\ y=215.02 \end{gathered}\)\(\begin{gathered} 2014\to x=14 \\ y=6.06(14)+136.24 \\ y=84.84+136.24 \\ y=221.08 \end{gathered}\)The following system of linear equations has how many solutions?

The system of linear equations 3y = x + 6 and 6y - 2x = 12 has infinitely many solutions.
What is the number of solutions of the system of equation?Given the system of euqation in the question;
3y = x + 66y - 2x = 12We can solve this system of linear equations using the substitution method:
From the first equation, we can rewrite x in terms of y as:
x = 3y - 6
Substituting this expression for x in the second equation, we get:
6y - 2(3y - 6) = 12
Simplifying this equation, we get:
6y - 6y + 12 = 12
The equation simplifies to 12 = 12.

Determine P(Service Brokerage or Online)
In probability:

In this case:
\(P(Service\ Brokerage\ or\ Online) = P(Service\ Brokerage) + P(Online) - P(Both)\)

Hence, the required probability is 66%
