Becky worked part-time at a restaurant. The amount of money she earned for each of six weeks is shown.

OA. The median decreases and the mean remains the same.
OB. The mean and the median both decrease.
OC. The median and the mean both remain the same.
OD. The mean decreases and the median remains the same.
Answer:
Step-by-step explanation:
To answer this question, we need to calculate the mean and median of the given data set and then see how the additional earnings affect them.
First, let's calculate the mean of the original data set:
Mean = (50 + 82 + 39 + 50 + 31 + 70) / 6 = 322 / 6 = 53.67
Next, let's calculate the median of the original data set. To do this, we need to arrange the data set in order:
31, 39, 50, 50, 70, 82
The median is the middle value, which is 50.
Now, let's add Becky's earnings of $23 to the data set:
31, 39, 50, 50, 70, 82, 23
The new data set has 7 values. Let's calculate the new mean:
Mean = (50 + 82 + 39 + 50 + 31 + 70 + 23) / 7 = 365 / 7 = 52.14
The new mean is less than the original mean, so we can eliminate options A and C.
Now let's calculate the new median. We need to arrange the data set in order:
23, 31, 39, 50, 50, 70, 82
The median is still 50.
Therefore, the answer is option D: The mean decreases and the median remains the same.
new car is purchased for 18700 dollars. The value of the car depreciates at
14.25% per year. To the nearest year, how long will it be until the value of the
car is 3000 dollars?
The minimum time required to depreciate the value of the car is 12 years.
Let us assumed the time to be t. Representing the formula for calculation of time-
Final value = Principal value × [tex] {(1 - rate of depreciation)}^{t} [/tex]
Keeping the values in formula to find the time period
3000 = 18700 × [tex] {(1 - 14.25%)}^{t} [/tex]
Solving the expression
[tex] {(0.8575)}^{t} [/tex] = 3000/18700
Cancelling zeroes common in numerator and denominator
3000/18700 = [tex] {(0.8575)}^{t} [/tex]
Taking log on both sides of the equation
t log 0.8575 = 30/187
Keep the value
t = log 0.8575 30/187
t = 12 years
Hence, it will take 12 years for value depreciation.

We often use the phrase "to the power of" when talking about exponents. For example, x¹3 is
referred to as x to the power of 13. Why do you think that they would name it like this? How does
increasing the exponent of a number increase its "power"?
Hint: Use a number as an example. (for instance 2) if you keep increasing the power, what happens
to the answer? (i.e. compare 2¹, 2^2, 2^3, 2^4,..., 2^13, 2^14,... until you see the answer you are looking
for!)
In mathematics, the expression "to the power of" pertains to the exponent, signifying how many times a key number is to be multiplied by itself.
What is the exponents about?Expressing this idea in English can be done well by using the term "to the power of." To show this, 2 raised to the third power can be interpreted as 2 multiplied by itself three times, resulting in 8.
Therefore, the possible reason behind using the word "power" is probably due to the fact that when the exponent rises, the outcome number is wide, either being greater or smaller, made on the base being above or below 1. This implies that the figure holds more significant value.

Since t is the number of years since 1910, we can find the t value we need for the equation by subtracting 1910 from 1980:
t = 1980 - 1910 = 70
Now, we can plug in 70 for t to find the amount of currency in 1980:
[tex]M(t)=2.08(1.06)^t\\M(70)=2.08(1.06)^7^0\\M(70)=122.8779348\\M(70)=122.88[/tex]

The total amount of FICA tax that was deducted from the executive's paychecks for the year 2018 is $10,860.80.
What is the total amount of FICA tax?The FICA tax is imposed on both employees and employers to fund Social Security and Medicare which are federal programs that provide benefits for retirees, the disabled and children of deceased workers.
The Social Security tax will be calculated on the maximum taxable earnings of $128,400:
= $128,400 x 6.2%
= $7,961.20
The Medicare tax will be calculated on the entire earnings:
= $200,000 x 1.45%
= $2,900.
The total FICA tax will be:
= Social Security tax + Medicare tax
= $7,960.80 + $2,900

The radius of a circle is 12 cm. Find its area nearest whole number
Answer:
452 square centimeters.
Step-by-step explanation:
To find the area of a circle, we use the formula:
A = πr^2
Where A is the area of the circle, r is the radius, and π is a mathematical constant (approx. 3.14).
Given that the radius of the circle is 12 cm, we can substitute r = 12 in the formula:
A = π(12)^2
A = 3.14 x 144
A = 452.16
Therefore, the area of the circle is approximately 452.16 square centimeters. However, we need to round the answer to the nearest whole number.
Since the decimal part of the answer is less than 0.5, we round the answer down to the nearest whole number. Therefore, the area of the circle nearest the whole number is 452 square centimeters.

Describe los Tipos de ángulos que se forman cuando divides un círculo en 4 partes iguales
The angles that you get when a circle is divided into 4 equal parts, would be four 90 degree angles.
How to describe the angles ?The reason these angles are called 'right angles' is because they create an exact 90-degree angle, signifying one fourth of a complete circle. Every specific angle is named as a 'quadrant,' as it covers a quarter or a quadrant of the circle.
These four perpendicular angles stand side by side - having in common not just one diameter of the circle but also a shared vertex, which is at the center of the circle. Together, they share uniformly the circle into four unique sections - each turning toward a distinct quadrant of the circle parallel to their placement.
