a turn selecting a gift
without replacing it. What
is the probability that the
first gift chosen is
Monopoly and the second is
Scrabble?
To find the probability of selecting Monopoly as the first gift and Scrabble as the second gift without replacement, we need to consider the total number of board games and the number of favorable outcomes. Hence, the probability that the first gift chosen is Monopoly and the second gift is Scrabble is 1/90.
Let's assume there are 10 different board games in the pile. The first person chooses a gift, and since they want to select Monopoly, there is 1 favorable outcome out of the 10 board games. After the first gift is chosen, there are now 9 board games remaining, with 1 of them being Scrabble, which is the desired outcome for the second gift.
The probability of the first gift being Monopoly and the second gift being Scrabble without replacement can be calculated as the product of the probabilities of each event. The probability of choosing Monopoly as the first gift is 1/10, and the probability of choosing Scrabble as the second gift is 1/9.
Therefore, the overall probability can be calculated as (1/10) * (1/9) = 1/90.

A worker takes 5 hours to make 300 deyasHow much hours will a worker take to make 45 deyas
We can use a proportion to determine how long it would take a worker to make 45 days.
Let's set up the proportion:
(5 hours) / (300 deyas) = (x hours) / (45 deyas)
To solve for x, we can cross-multiply and then divide:
5 hours * 45 deyas = 300 deyas * x hours
225 hours = 300 deyas * x hours
Now, divide both sides by 300 days to isolate x:
x hours = 225 hours / 300 deyas

When two straight lines or rays intersect at a single endpoint, an angle is created. The vertex of an angle is the location where two points come together. The Latin word "angulus," which means "corner," is where the term "angle" originates.
We are given that ,
[tex]$AD \cong AE$, $BA || CE$, $CB || DA$, and $m\angle DAE = 52^\circ$.[/tex]
To find [tex]$m\angle BAD$[/tex], we need to use the fact that
[tex]$BA || CE$ and that $AD \cong AE$.[/tex]
Statement: Given
[tex]$AD \cong AE$, $BA || CE$, $CB || DA$ and $\angle DAE = 52^\circ$.[/tex]
To find: [tex]$\angle BAD$.[/tex]
Solution:
Here is the figure that represents the given statements:
As we know that [tex]$BA || CE$[/tex],
so we can say that [tex]$\angle DAE$[/tex] and [tex]$\angle ECD$[/tex] are corresponding angles.
Thus, [tex]$\angle ECD = 52^\circ$.[/tex]
In [tex]$\triangle ACE$[/tex] , we have [tex]$\angle ACE + \angle ECD + \angle AEC = 180^\circ$[/tex].
As [tex]$CE || BA$, $\angle AEC = \angle BAD$[/tex]
So, we have [tex]$\angle ACE + \angle ECD + \angle BAD = 180^\circ$[/tex]
Putting values of [tex]$\angle ECD$ and $\angle ACE$[/tex] in the above equation,
we get
[tex]\begin{align*}\angle BAD + \angle ACB + 52^\circ &= 180^\circ \\ \Rightarrow \angle BAD &= 180^\circ - 52^\circ - 80^\circ \\ \Rightarrow \angle BAD &= 48^\circ\end{align*}Thus, the measure of $\angle BAD$[/tex] is [tex]$48^\circ$[/tex].

2
?
Therefore, the cost of white washing the walls will be Rs 5 × 588.72 = Rs 2943.60.
The total surface area of the four walls can be calculated by multiplying the perimeter of the room (2 × (length + width)) by the height of the room. In this case, the total surface area of the four walls is 2 × (16 + 14) × 10 = 600 square meters.
Next, we need to subtract the areas of the windows and doors from the total surface area of the walls. There are four windows with dimensions of 1.3 meters in height and 1.4 meters in width, so the total area of the windows is 4 × (1.3 × 1.4) = 7.28 square meters. There are also two doors with dimensions of 2 meters in height and 1 meter in width, so the total area of the doors is 2 × (2 × 1) = 4 square meters.
Subtracting the areas of the windows and doors from the total surface area of the walls, we get 600 square meters - (7.28 square meters + 4 square meters) = 588.72 square meters.
Finally, we can calculate the cost of white washing the walls by multiplying the rate per square meter (Rs 5) by the total surface area of the walls (588.72 square meters). Therefore, the cost of white washing the walls will be Rs 5 × 588.72 = Rs 2943.60.

The perimeter of a triangle is the sum of the lengths of all three sides. In this case, the perimeter is given as 39 units. We can set up an equation to solve for x:
x + 4x + 3x = 39
Combining like terms:
8x = 39
Dividing both sides by 8:
x = 39/8
Simplifying the fraction:
x = 4.875
Now, we can find the lengths of all three sides by substituting this value of x back into our expressions for each side:
Side one: x = 4.875 units
Side two: 4x = 4.875 * 4 = 19.5 units
Side three: 3x = 4.875 * 3 = 14.625 units
Therefore, the lengths of the three sides of the triangle are approximately:
Side one: 4.875 units
Side two: 19.5 units
Side three: 14.625 units

Darryl should add 8 gallons of water to the 8-gallon 10% bleach solution to make a 5% bleach solution.
Darryl should add 8 gallons of water to the 8-gallon 10% bleach solution to make a 5% bleach solution .The correct equation that Darryl can use to find x, the number of gallons of water he should add, is:
0.8 / (8 + x) = 5/100
Let's break down the equation and explain each part:
The numerator 0.8 represents the amount of bleach in the original 8-gallon solution.
The denominator (8 + x) represents the total volume of the new solution after adding x gallons of water.
5/100 represents the desired concentration of the new solution, which is 5% bleach.
By setting up this equation, we equate the amount of bleach in the original solution (0.8 gallons) to the amount of bleach in the new solution (5% of the total volume, which is (8 + x) gallons).
Simplifying the equation:
0.8 / (8 + x) = 5/100
To solve for x, we can cross-multiply:
0.8 * 100 = 5 * (8 + x)
80 = 40 + 5x
Subtracting 40 from both sides:
80 - 40 = 5x
40 = 5x
Dividing both sides by 5:
40 / 5 = x
8 = x
Therefore, Darryl should add 8 gallons of water to the 8-gallon 10% bleach solution to make a 5% bleach solution.

Calculate the trimmed mean for each sample by deleting the smallest and largest observation.What are the corresponding trimming percentages?
To calculate the trimmed mean for each sample by deleting the smallest and largest observation, we remove the extreme values and find the mean of the remaining data. The corresponding trimming percentage is the percentage of observations excluded from the calculation.
The trimmed mean is a way to reduce the influence of outliers or extreme values in a data set by excluding them from the calculation. By deleting the smallest and largest observations, we remove the outliers and focus on the central tendency of the data.
To find the trimming percentage, we need to determine the number of observations excluded relative to the total number of observations in the sample. Suppose the sample has "n" observations.
When we remove the smallest and largest values, we eliminate 2 observations. Therefore, the trimming percentage can be calculated as (2 / n) * 100.
For example, if the sample has 10 observations, the trimming percentage would be (2 / 10) * 100 = 20%. This means that the smallest and largest values are excluded, representing a trimming of 20% of the data.
In summary, the trimmed mean is calculated by removing the smallest and largest observations and finding the mean of the remaining values. The corresponding trimming percentage is determined by dividing the number of observations excluded by the total number of observations in the sample and multiplying by 100.

A patch in the shape of the region shown above is to be sewn onto a flag. If each unit in the coordinate system represents one foot, how much material is required for the patch?
a.
15.525 ft²
c.
10.525 ft²
b.
15.125 ft²
d.
10.125 ft²
The correct answer is option (b) 15.125 ft², representing the amount of material required for the patch.
The amount of material required for the patch, which is in the shape of the region defined by the equation y = (1/2)x^3, can be determined by calculating the area under the curve.
The patch's shape is defined by the equation y = (1/2)x^3. To find the area under the curve, we need to integrate the equation with respect to x over the appropriate interval. In this case, we are not given specific limits of integration, so we assume the interval is from x = 0 to x = 3 (based on the curve's shape shown in the equation).
The integral for finding the area under the curve is: A = ∫[0 to 3] (1/2)x^3 dx.
Evaluating the integral, we get: A = [(1/2) * (1/4)x^4] evaluated from 0 to 3.
Plugging in the limits, we have: A = (1/2) * (1/4) * (3^4 - 0^4) = (1/2) * (1/4) * (81 - 0) = (1/2) * (1/4) * 81 = 15.125 ft².
Therefore, the correct answer is option (b) 15.125 ft², representing the amount of material required for the patch.
