Answer:
deductive reasoning
Step-by-step explanation:
A two-child family is selected at random. Let B denote the event that at least one child is a boy, and let D denote the event that
the genders of the two children differ. Find the union of B and D. (1 point)
The union is (bb, gg); the first letter denotes the gender of the firstborn child, and the second letter denotes the gender of the
second child.
The union is (bg. gb); the first letter denotes the gender of the firstborn child, and the second letter denotes the gender of the
second child.
The union is {bb, bg, gb, gg); the first letter denotes the gender of the firstborn child, and the second letter denotes the gender of
the second child.
The union is (bb, bg. gb); the first letter denotes the gender of the firstborn child, and the second letter denotes the gender of the
second child.
With the help of probability we can say that, DUM={GG,BB,GB,BG).
What is Probability?Probability is the concept that describes the likelihood of an event occurring.
In real life, we frequently have to make predictions about how things will turn out.
We may be aware of the result of an occurrence or not.
When this occurs, we state that there is a possibility that the event will occur.
In general, probability has many excellent applications in games, commerce, and this newly growing area of artificial intelligence
The chance of an event can be calculated using the probability formula by only dividing the favourable number of possibilities by the total number of potential outcomes.
hence, DUM={GG,BB,GB,BG)

Si el volumen de una caja de cartón de forma cúbica es de 216 dm³
The volume of the cardboard box is approximately 13197.402 cubic inches.
The volume of a cardboard box is 216 dm³, we can convert it to the English system of measurements.
1 dm (cubic decimeter) is equivalent to 1 liter.
To convert dm³ to cubic inches, we can use the following conversion factors:
1 dm³ = 61.0237 cubic inches
Using this conversion factor, we can calculate the volume of the box in cubic inches:
The cube carton volume is 216 dm3 and the cube edge value is 6 dm.
The volume of the cube is calculated by dividing the edge values. In other words, volume = edge 3.
To find the edge (side) value, you can solve for the volume formula as follows:
edge 3 = volume.
edge = ∛ volume,
Where ∛ is the cube root.
Applying this formula to the given problem gives edge = ∛(216 dm³).
Edge = 6dm. Therefore, the side (edge) value of the cube is 6dm.
Volume (cubic inches) = 216 dm³ * 61.0237 cubic inches/dm³
= 13197.402 cubic inches

a Given p(x) = X+41, what is (-10)?
Answer:
p(-10) = 31
Step-by-step explanation:
Plug in -10 as x into the equation, and solve
p(x) = x + 41
p(-10) = -10 + 41
p(-10) = 31
Given : p(x) = x + 41
We have to find value of p(-10)\(.\)
➙ p(x) = x + 41
By substituting x = (-10), we get
➙ p(-10) = (-10) + 41
➙ p(-10) = 41 - 10
➙ p(-10) = 31

5. The surface area of a cuboid is 518 cm².
The breadth of the cuboid is 11 cm and its
height is 9 cm. Find the length of the cuboid.
The correct answer is 8 cm.
Given the surface area = 518 cm²
breadth of the cuboid = 11 cm
height of the cuboid = 9 cm
Now let l be the length of the cuboid,
The total surface area (TSA) of a cuboid is provided by the sum of the areas of its six rectangles, where l, b, and h are the length, width, and height, respectively
Cuboid's total surface area formula,
Thus the surface area of the cuboid = 2(lb+bh+lh)
518 = 2 ( l × 11 + 11 × 9 + l × 9 )
518 = 2 (11l + 99 + 9l)
259 = 11l +99 +9l
259 - 99 = 20 l
160/20 =l
length = 8 cm

The height of the building is approximately 78.63 meters.
The following is a step-by-step explanation of how to solve the problem. We'll need to use some trigonometric concepts and formulas to find the solution.
Draw a diagram of the situation described in the problem to get a better understanding of the problem. The diagram would have a right-angled triangle with angle of elevation of 66° at the bottom left vertex and another angle of elevation of 53° at the bottom right vertex. The object on top of the building is at the vertex of the triangle. Point M and I on the diagram are points on the horizontal line of sight and on the ground respectively. We can label the diagram with the following values:Angle of elevation from point A = 66°Angle of elevation from point P = 53° Length of line segment AM = h Length of line segment MP = x Length of line segment IP = y Length of line segment MT = 50m. We'll use these values to calculate the length of h, which is the height of the building.Use the tangent ratio to find x:tan 66° = h / x => x = h / tan 66°. Use the tangent ratio to find y:tan 53° = h / y => y = h / tan 53°.We know that x + y = 50, so substituting the expressions for x and y from step 3 gives:h / tan 66° + h / tan 53° = 50h = 50 tan 66° tan 53° / (tan 53° + tan 66°) ≈ 78.63 m.Therefore, the height of the building is approximately 78.63 meters.

Using the formula developed by Dr's Mosteller, doctors can approximate the Body Surface Area TIW (BSA) of an adult The formula is written as BSA where H is the Height in cm and W is 3800 the Weight in kg: If the BSA of a certian adult is 96 whose height Is 210 cm. About how much does this adult weight? The adult weights (Round t0 decimal place )
From the body surface area formula, the adult weight is 508.97.
The Mosteller formula takes the square root of the height multiplied by the weight divided by 3600
The Body Surface Area TIW (BSA) of an adult.
The formula is written as BSA
where H is the Height(cm), Weight is 3800(kg)
BSA=96
Height=210cm
BSA=\(\sqrt{\frac{H*W}{3600} }\)
\(96=\sqrt{\frac{210*W}{3600} \\\)
\(96=\frac{\sqrt{210*W}}{\sqrt{3600} } \\96=\frac{14.49*\sqrt{W}\\}{61.64}\\ 96=\frac{\sqrt{W} }{0.235}\\ 96*0.235=\sqrt{W}\\ 22.56=\sqrt{W}\\\)
Squaring on both sides
508.97=W

Chloe’s Cafe bakes croissants that it sells to local restaurants and grocery stores. The average costs to bake the croissants are $0.40 for 2,000 and $0.35 for 4,000.If the total cost function for croissants is linear, what will be the average cost to bake 3,200?
Answer: First step is to determine the total cost
Total cost at 2,800
=$0.80 ×2,800
=$2,240
Total cost at 5,600
=$0.75 × 5,600
=$4,200
Second step is to determine the Variable cost per unit
Variable cost per unit=$4,200-$2,240
Variable cost per unit=$1,960
Variable cost per unit=5,600-2,800
Variable cost per unit=2,800
Variable cost per unit=$1,960/2,800
Variable cost per unit=$0.70
Now let determine the average cost
Average cost=$0.70×4,800+[($0.80×2800)-(2,800 ×$0.70)]
Average cost=$3,360+($2,240-$1,960)
Average cost=$3,360+$280
Average cost=$3,640
Average cost =$3,640/4,800
Average cost=$0.76
In conclusion What will be the average cost to bake 4,800 is $0.76

Suppose that you are taking a course that has 4 tests. The first three tests are each worth 20% of your final grade, and the fourth test is worth 40% of the final grade. To get a B in the course, you must have an average of at least 80 percent on the 4 tests. Your scores on the first 3 tests were 63.5 %, 76 %, and 87 %. What is the minimum score you need on the fourth test to get a B for the course?. Don't round your answer.
Answer:
86.75
Step-by-step explanation:
Given test scores of 63.5, 76, and 87 that each count for 20% of your grade, you want to know the fourth test score needed for an average of 80, if the fourth test is worth 40% of your grade.
Course gradeThe grade for the course, with fourth test score x, will be ...
0.20(63.5 +76 +87) +0.40x = 80
0.40x +45.3 = 80
Solving for x, we get ...
0.40x = 34.7 . . . . subtract 45.3
x = 86.75 . . . . . . . divide by 0.4
The minimum score you need on the fourth test is 86.75.

What is the equation of a line that is parallel to 2x + 3y = 3 and passes through the point (3, -4)?
Enter your answer as a slope intercept equation (y=mx+b) in the box.
Answer:
y = - \(\frac{2}{3}\) x - 2
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
given
2x + 3y = 3 ( subtract 2x from both sides )
3y = - 2x + 3 ( divide through by 3 )
y = - \(\frac{2}{3}\) x + 1 ← in slope- intercept form
with slope m = - \(\frac{2}{3}\)
• Parallel lines have equal slopes , then
y = - \(\frac{2}{3}\) x + b ← is the partial equation
to find b substitute (3, - 4 ) into the partial equation
- 4 = - 2 + b ⇒ b = - 4 + 2 = - 2
y = - \(\frac{2}{3}\) x - 2 ← equation of parallel line
