If y varies directly as x, and y=6 when x=15, find y when x=2.
A.) 4/5
B.) 4
C.) 5
d.) 5/4
Answer:
Option A: 4/5
Step-by-step explanation:
If y varies directly as x written as y ∝ x, this can be written as an equation:
y = kx where k is a constant
Since y = 6 when x = 15:
6 =k · 15
6 = 15k
15k = 6
k = 6/15 = 2/5
The equation beocmes
y = (2/5) x
Therefore when x = 2,
y = (2/5) x 2 = 4/5
Option A: 4/5

The $30,000 in revenue should be entered as a credit in the journal entry.
Step-by-step explanation:
In accounting, revenues are recorded as credits, which means that they increase the credit side of the accounting equation (revenues increase equity, which is a credit account). Debits, on the other hand, are used to record expenses and decreases in assets.Therefore, the journal entry to record $30,000 in revenue for the business on October 1 would be:Date
Account Account Number Debit Credit

Answer:
rectangle: 30 ft²triangle: 12 ft²total: 42 ft²Step-by-step explanation:
You want the area of the composite figure consisting of a rectangle and a triangle.
RectangleThe area of the rectangle is ...
A = LW
A = (5 ft)(6 ft) = 30 ft² . . . . rectangle area
TriangleThe base of the triangle is the difference in length of the horizontal segments:
b = 9 ft -5 ft = 4 ft
The area is given by the formula ...
A = 1/2bh
A = 1/2(4 ft)(6 ft) = 12 ft² . . . . triangle area
Total areaThe area of the figure is the sum of the areas of its parts:
total area = rectangle area + triangle area
total area = 30 ft² +12 ft²
total area = 42 ft²
__
Additional comment
The area of this trapezoid can also be found using the trapezoid formula:
A = 1/2(b1 +b2)h
A = 1/2(9 ft +5 ft)(6 ft) = 42 ft²
The rectangle is shown in the figure as 5 ft wide and 6 ft tall. It does not matter which of these dimensions you call the length and which you call the width. Their product is the same either way.

Solve for the length of the unknown side in the following right triangle. (Side AC is the hypotenuse.) Round your answer to two places, where applicable. Side AB 17, Side BC 22, Side AC ?
Answer:
27.87
Step-by-step explanation:
In a right triangle, the length of the hypotenuse can be found using the Pythagorean theorem, which states that the sum of the squares of the two shorter sides is equal to the square of the length of the hypotenuse.
Using the given sides, we can write the equation:
AB^2 + BC^2 = AC^2
Substituting the given values, we have:
17^2 + 22^2 = AC^2
Simplifying the left side, we get:
289 + 484 = AC^2
773 = AC^2
Taking the square root of both sides, we find:
AC = √773 = 27.87
Rounding to two decimal places, the length of side AC is approximately 27.87.

Solve using elimination. 3x - 2y = 10 3x - y = 17
The first step is to rewrite the equations in standard form by subtracting the constant from each side.
What is standard form ?Standard form is a type of numerical notation used to express large numbers in a concise form. It is based on powers of 10, which means each place value of a number is multiplied by a power of 10. Standard form is typically used in scientific and mathematical applications, and it is also known as scientific notation. To write a number in standard form, the number is written as a coefficient, followed by the base of 10, raised to an exponent.
3x - 2y = 10 becomes 3x - 2y - 10 = 0
3x - y = 17 becomes 3x - y - 17 = 0
Let's multiply the first equation by 2 and the second equation by 3.
2(3x - 2y - 10) = 0
3(3x - y - 17) = 0
6x - 4y - 20 = 0
9x - 3y - 51 = 0
The next step is to add the two equations together.
6x - 4y - 20 + 9x - 3y - 51 = 0
15x - 7y - 71 = 0
The last step is to solve for the variable.

Which of the following is not true of slope of the least-squared regression line?The square of the slope equals the fraction of the variation in the response variable that is explained by the explanatory variable, it is unit less.
The slope of the least-squares regression line is not directly related to the fraction of the variation in the response variable that is explained by the explanatory variable.
The slope of the least-squares regression line is a numerical measure of the rate of change in the response variable for a unit change in the explanatory variable. It does not directly relate to the fraction of the variation in the response variable that is explained by the explanatory variable. This is because the fraction of the variation in the response variable that is explained is determined by the correlation coefficient, which is a measure of how well the regression line fits the data. The slope of the least-squares regression line is unitless, meaning it does not have any specific unit such as meters, seconds, or degrees. The slope of the least-squares regression line is simply a numerical measure of the rate of change in the response variable per unit change in the explanatory variable. This is different from the fraction of the variation in the response variable explained by the explanatory variable, which is determined by the correlation coefficient.

What is meant by probability?
The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.
Given,
Percentage of people who buys 4 tires = 50%
Percentage of people who buys 2 tires = 32%
Percentage of people who buys less than 2 tires = 13%
Percentage of people who buys none = 6%
a) Prob(X=0) = 0.06
Prob(X=2) = 0.32
Prob(X=4) = 0.50
Prob(X < 2) = Prob(X=0) + prob(X=1) = 0.06+ prob(X=1)
prob(X=1) = Prob(X < 2) - 0.06 = 0.13 - 0.06 = 0.07
Therefore prob(X = 3) = 1 - ( 0.5+0.32+0.07+0.06) = 1 - 0.95 = 0.05 = 5%

Answer:
a. 1996
Step-by-step explanation:
Let Paul's age in 2000 be P
Let Bilko's age in 2000 be B
Statement: Paul was twice as old as his brother Biko in 2000 means
P = 2B (1)
In 2008 Paul was only four years older than his brother.
Since 2008 is 8 years from 2000, both Paul and Bilko have aged 8 years
Paul's age in 2008 = P + 8
Bilko's age in 2008 = B + 8
Statement: In 2008 Paul was only four years older than his brother means
P + 8 = B + 8 - 4
P = B + 4 (2)
Given these two equations (1) and (2)
Substitute P = 2B from (1) in (2):
2B = B + 4
==> 2B - B = 4
==> B = 4
Therefore in 2000, Paul was 8 years old and Bilko was 4 years old
Bilko's year of birth = 2000 - 4 = 1996

g(x) =f(x) + N
if N > 0, the translation is up
if N < 0, the translation is down.
A horizontal translation of N units as:
g(x) =f(x + N)
if N > 0, the translation is left
if N < 0, the translation is to the right.
Here we have:
g(x) = f(x + 1) + 3
So we have a translation of 1 unit to the left and 3 units up.

the mean is an inappropriate measure of central tendency when the distribution is severely skewed because
The mean is sensitive to outliers and will not accurately represent the center of the data if the distribution is significantly skewed.
The mean is a measure of central tendency that is calculated by adding up all values in a dataset and dividing by the number of values. It is often used as a measure of average since it takes into account all values in the dataset. However, it is an inappropriate measure of central tendency when the data distribution is severely skewed. A skewed distribution is one in which the data is not distributed evenly around the mean, and the data is either concentrated in the lower or higher end of the range. Since the mean is sensitive to outliers, it will be greatly affected by these values and not accurately represent the center of the data. In this case, it is more appropriate to use the median as a measure of central tendency since it is not affected by outliers. The median is the middle value of a dataset when the data is sorted from smallest to largest and is a better representation of the true center of the data in a skewed distribution.

55 hours in one week with $15 per hour. What’s gross pay, assuming overtime is time and a half?
Answer:
Step-by-step explanation:
If you work 55 hours in one week and earn $15 per hour, your gross pay before taking into account any overtime can be calculated as follows:
Gross pay = 55 hours x $15/hour = $825
If you work overtime, which is time and a half, the additional pay can be calculated as follows:
Overtime pay = ($15/hour x 1.5) x (55 hours - 40 hours) = ($22.50/hour x 15 hours) = $337.50
So, the total gross pay including the overtime pay is:
Gross pay = $825 + $337.50 = $1,162.50
Therefore, the total gross pay for working 55 hours in one week at $15 per hour, with overtime pay calculated as time and a half, is $1,162.50.
