An automobile purchased for use by the manager of a firm at a price of $32,500 is to be depreciated by using the straight-line method over 5 years. What will be the book value of the automobile at the end of 3 years? (Assume that the scrap value is $0.) $
The book value of the automobile at the end of 3 years is $13,000.
What is the book value?The straight-line method is method of depreciation that allocates the same depreciation expense each year.
Straight line depreciation expense = (Cost of asset - Salvage value) / useful life
($32,500 - 0) / 5 = $6,500
Total depreciation in 3 years = $6,500 x 3 = $19,500
Book value = cost of the automobile - total depreciation
$32,500 - $19,500 = $13,000

Which triangle could be drawn as it is described?
The triangle which can be drawn as per the condition described is only option 2. an isosceles triangle with measure 20° and 80°.
Triangle which can be drawn as per the measurements are,
An acute triangle with sides measuring 7, 4, 2.
In an acute triangle, the square of the longest side is less than the sum of the squares of the other two sides.
According to the Pythagorean theorem.
7²< 4² + 2²
49 < 16 + 4
49 < 20
This is a contradiction, since 49 cannot be less than 20.
It is not possible to draw triangle.
An isosceles triangle with measures of angle 20° and 80°.
Sum of interior angles of a triangle is 180°
Here, third angle = 180° - ( 20° + 80° )

In 2016 , a clinical study in a small town of New Hampshire found that about 13 % of its population had the flu . The study also showed that 19 % of the people who had the flu tested negitive while 8% of of the people who did not have the flu tested positive . based on the given information construct a realative frequency table.
The relative frequency of a person having the flu and testing positive for the flu is 0.1053/0.901 = 0.117, or approximately 11.7%. The relative frequency table is given below.
To get the relative frequencies, we divide each cell value by the total frequency of the table.
This is how we construct relative frequency table.
To construct a relative frequency table, we need to determine the different possible outcomes and their corresponding frequencies based on the given information.
Let's define the following events:
A: a person has the flu
B: a person tests positive for the flu
Then, using the information given in the problem, we can construct the following relative frequency table:
A (has the flu) not A (does not have the flu) Total
B 0.13*0.81 = 0.1053 0.08*0.87 = 0.0696 0.1749
not B 0.19*0.81 = 0.1540 0.63*0.87 = 0.5471 0.7011
To 0.2843 0.6171 0.901
In this table, the values in the cells represent the product of the probability of the row event and the probability of the column event. For example, the value 0.1053 in the top left cell represents the probability of a person having the flu (event A) and testing positive for the flu (event B), which is calculated as 0.13 x 0.81.
The total frequency for each row and column is calculated by summing the values in that row or column. The total frequency for the entire table is the sum of all the values, which is 0.901 in this case.

i) There is no solution for x when y<0.
ii) When y>0, the solutions for x are x=4 and x=0.
iii) When y=0, the solutions for x are x=4 and x=0
To use a graph to find the value of x for the given values of y in the equation y=-|x-2|+2, we can follow these steps:
i) When y<0:
The graph of y=-|x-2|+2 is below the x-axis when y<0. Therefore, there is no solution for x when y<0, because there is no point on the graph that has a negative y-coordinate.
ii) When y>0:
The graph of y=-|x-2|+2 intersects the x-axis at two points when y>0. To find the x-coordinates of these points, we can set y=0 in the equation y=-|x-2|+2 and solve for x, as shown in the previous answer.
The x-intercepts are at (4,0) and (0,0), which means that the graph crosses the x-axis at x=4 and x=0 when y>0.
iii) When y=0:
To find the x-coordinate(s) of the point(s) where the graph intersects the x-axis (i.e., where y=0), we can look at the x-intercepts that we found in part ii) above. The x-coordinate(s) of the point(s) where the graph intersects the x-axis are x=4 and x=0, so the solutions for x when y=0 are x=4 and x=0.
Therefore, i) There is no solution for x when y<0.
ii) When y>0, the solutions for x are x=4 and x=0.
iii) When y=0, the solutions for x are x=4 and x=0 (the x-intercepts).

To achieve this goal, how much money does the couple need to have in this account by the time they retire?
If they have not saved any money yet, how much does the couple need to deposit each month end until they retire?
The couple needs to deposit about $554.49 each month end until they retire to reach their goal.
How to solveTo find the monthly deposit needed, we'll use the future value of an ordinary annuity formula:
FV = PMT * [((1 + r)^n - 1) / r]
We already know the future value (FV) as $953,776.53, and we want to solve for PMT, the monthly deposit:
PMT = FV / [((1 + r)^n - 1) / r]
We'll use the same r (0.08/12) and a new n (35 * 12) for the 35 years until retirement:
PMT = 953776.53 / [((1 + 0.08/12)^(35*12) - 1) / (0.08/12)]
PMT ≈ 554.49
Thus, the couple needs to deposit about $554.49 each month end until they retire to reach their goal.

If (2x, x + 17, x + 21, ....) is an arithmetic sequence find the value of x ?
Answer:
Since (2x, x + 17, x + 21, ...) is an arithmetic sequence, we know that the common difference between consecutive terms is constant.
The common difference can be found by subtracting any two consecutive terms in the sequence. Let's subtract the second term (x + 17) from the first term (2x):
2x - (x + 17) = x - 17
Now let's subtract the third term (x + 21) from the second term (x + 17):
(x + 17) - (x + 21) = -4
Since the common difference is constant, we can set the two expressions for the common difference equal to each other:
x - 17 = -4
Solving for x, we get:
x = 13
Therefore, the value of x that makes the sequence (2x, x + 17, x + 21, ...) an arithmetic sequence is x = 13.

A carnival game has 160 rubber ducks floating in a pool. The person playing the game takes out one duck and looks at it.
If there’s a red mark on the bottom of the duck, the person wins a small prize.
If there’s a blue mark on the bottom of the duck, the person wins a large prize.
Many ducks do not have a mark.
After 50 people have played the game, only 3 of them have won a small prize, and none of them have won a large prize.
Estimate the number of the 160 ducks that you think have red marks on the bottom.
Answer:
We can use the information provided to estimate the number of ducks that have red marks on the bottom.
If only 3 out of 50 people have won a small prize, then we can estimate that the probability of winning a small prize is 3/50 or 0.06. Since the person wins a small prize if there’s a red mark on the bottom of the duck, we can estimate that the proportion of ducks with red marks is also 0.06.
So, we can estimate the number of ducks with red marks as follows:
Number of ducks with red marks = 0.06 x 160
Number of ducks with red marks = 9.6
We can estimate that there are about 9 or 10 ducks with red marks on the bottom.
