Final answer:
To find the total number of cars sold in Chicago, we can use percentages and proportions. We can set up a proportion and solve for the unknown variable. The total number of cars sold in Chicago is 1700.
Explanation:
To solve this problem, we can use the concept of percentages and proportions. We are given that 85% of all cars sold in Chicago are some color other than black, and we also know that 300 black cars were sold. We need to find the total number of cars sold in Chicago.
First, let's find the ratio of black cars to colored cars. Since the percentage of colored cars is 85%, the percentage of black cars would be 100% - 85% = 15%. We can express this as a ratio by writing it as 15/100.
Now, let's set up a proportion:
x/300 = 85/15
Next, we can cross-multiply and solve for x:
15x = 300 * 85
x = (300 * 85) / 15
x = 1700
Therefore, the total number of cars sold in Chicago is 1700.

The total amount of money in a savings account after t years is given by the function A=1000(1.023)^t .
How could this function be rewritten to identify the monthly interest rate?
What is the approximate monthly interest rate?
Drag and drop the choices into the boxes to correctly complete the table. If a value does not match, do not drag it to the table.
Function Monthly interest rate
A = 1000(1 + 0.023)^12t
A = 1000(1.023^12)^t/12
A = 1000(1.023^t/12)^12t
0.23%
0.19%
0.31%
Answer:
[tex]A=1000(1+\frac{0.023}{12})^{12t}[/tex]
Rate of interest (r) = 0.19% monthly
Step-by-step explanation:
Given: The total amount of money in a saving account after t years.
[tex]A=1000(1.023)^t[/tex]
Formula:
[tex]A=P(1+r)^t[/tex]
Now we compare this formula with with given model.
P=1000
Rate of interest annually (r) = 0.023
Time = t
We need to change into monthly interest
New rate will divide by 12
New time will multiply by 12
[tex]r=\frac{0.023}{12}=0.0019[/tex]
[tex]t=12\times t =12t[/tex]
Function for monthly rate
[tex]A=1000(1+\frac{0.023}{12})^{12t}[/tex]
Rate of interest (r) = 0.19% monthly
[tex]\text{Thus, Function Monthly interest rate: }A=1000(1+\frac{0.023}{12})^{12t}\text{ and Monthly Interest rate }= 0.19\%[/tex]

Which of the following are NOT sufficient to prove that a quadrilateral is a parallelogram? I. Two pairs of opposite angles congruent. II. A pair of adjacent angles are supplementary. III. Both pairs of opposite sides are congruent. IV. A pair of opposite angles congruent and a pair of opposite sides congruent. V. Both pairs of opposite sides are parallel. VI. A pair of opposite sides parallel and the other pair of opposite sides congruent. VII. One pair of opposite sides are both parallel and congruent. VIII. The diagonals bisect each other. A. IV and VII only B. II, VI, and VII only C. II and VI only D. II, IV, and VII only
A pair of adjacent angles being supplementary, a pair of opposite angles congruent and a pair of opposite sides congruent, and one pair of opposite sides being both parallel and congruent are not sufficient conditions on their own to prove that a quadrilateral is a parallelogram.
Among the given statements concerning the characteristics that are sufficient to prove a quadrilateral is a parallelogram, the following are NOT sufficient on their own:
A pair of adjacent angles are supplementary (statement II).
A pair of opposite angles congruent and a pair of opposite sides congruent (statement IV).
One pair of opposite sides are both parallel and congruent (statement VII).
While having a pair of adjacent angles that are supplementary is common in parallelograms, it alone does not guarantee that a quadrilateral is a parallelogram, as many quadrilateral types can have supplementary adjacent angles. Similarly, having just one pair of opposite angles and one pair of opposite sides congruent doesn't necessarily make a quadrilateral a parallelogram, as these characteristics could describe a kite or other quadrilaterals as well. The condition of one pair of opposite sides being both parallel and congruent, although a property of parallelograms, is not by itself a conclusive proof, as there may need to be additional information to rule out other shapes like rectangles.
Correct Answer: B. II, VI, and VII only

Using a six-sided die, what is the probability of rolling either a 5 or a 6?
The probability of rolling either a 5 or a 6 using a six-sided die is 1/3.
What is probability?Probability is the extent to which an event is likely to occur, measured by the ratio of the favorable cases to the whole number of cases.
Now it is given that a six-sided die is rolled.
Total Number of outcomes = 6
To get either a 5 or a 6
So, Possible number of outcomes = 2
Since ,
Probability = Possible number of outcomes / Total Number of outcomes
⇒ Probability of rolling either a 5 or a 6 = 2/6
or, Probability of rolling either a 5 or a 6 = 1/3
Thus, the probability of rolling either a 5 or a 6 using a six-sided die is 1/3.

Jill Hartman earns $750 per week plus 3% of sales in excess of $6,500. If Jill sells $25,000 in the first week, her earnings are:
The earnings of Jill Hartman for the week is A = $1,305
Given data ,
To calculate Jill's earnings for the first week, we need to determine the amount of sales in excess of $6,500 and then calculate her additional earnings based on that amount.
Sales in excess of $6,500 = Total sales - $6,500 = $25,000 - $6,500 = $18,500
Now we can calculate Jill's additional earnings based on the sales in excess of $6,500:
Additional earnings = 3% of sales in excess of $6,500 = 0.03 * $18,500
Additional earnings = $555
Finally, we can calculate Jill's total earnings for the first week by adding her base salary to her additional earnings:
Total earnings = Base salary + Additional earnings = $750 + $555
Total earnings = $1,305
Hence , Jill's earnings for the first week, with sales of $25,000, are $1,305

When the mean, median, and mode are not in the same place, the distribution is:?
When the mean, median, and mode are not located at the same point, the distribution is skewed, either to the left (negatively skewed) or to the right (positively skewed).
Explanation:When the mean, median, and mode are not in the same place, the distribution is known to be skewed. If the mean is less than the median, which is often less than the mode, the distribution is skewed to the left (or negatively skewed). Conversely, if the mode is less than the median, which is less than the mean, the distribution is skewed to the right (or positively skewed). Skewness indicates that the data is not symmetrically distributed and reflects the direction of the tail where the values trail off more.
In symmetrical distributions, the mean, median, and mode are all located at the same point, typically at the center of the distribution. However, when the values are not symmetrical, it indicates a skew. For example, in a data set with the values 4, 5, 6, 6, 6, 7, 7, 7, 7, 8, the distribution is not symmetrical since it is skewed to the left, with a higher frequency of higher values.
Thus, understanding the relationship among the mean, median, and mode helps in recognizing the type of distribution and in making inferences about the data set.
