the probability of a randomly selected person having a birthday in August is 1/12 or 0.0833 rounded to four decimal places.

The probability of a randomly selected person having a birthday in August is 1/12. There are 12 months in a year and August is one of them. Therefore, The probability of a randomly selected person having a birthday in August is 1/12 because there are 12 months in a year and August is one of them. Each month has an equal chance of being chosen since they all have the same number of days. This probability remains the same regardless of whether or not it is a leap year. Therefore, the probability of a randomly selected person having a birthday in August is 1/12 or 0.0833 rounded to four decimal places.The probability of a randomly selected person having a birthday in August is calculated by dividing the number of days in August (31) by the total number of days in a year (365). This works out to be 1/12 or 0.0833 rounded to four decimal places.

Step-by-step explanation: To solve this inequality, we can first isolate the absolute value term on one side of the inequality by subtracting |n-2| from both sides of the inequality. This gives us the inequality -3 + |n-2| > 2. Then, we need to consider two cases: when |n-2| is positive and when |n-2| is negative.

If |n-2| is positive, then we can drop the absolute value bars and rewrite the inequality as -3 + (n-2) > 2. Solving this inequality, we find that n > 7.

If |n-2| is negative, then we must reverse the direction of the inequality because subtracting a negative number is the same as adding a positive number. This gives us the inequality -3 - (n-2) > 2. Solving this inequality, we find that n < -1.

Therefore, the solution to the inequality is the set of all numbers that are greater than 7 or less than -1, which is the interval (-1, 7).

Number of square feet of wall painted in 1 hour is 243 square feet. Therefore, option C is the correct answer.

Given that, it takes Zach 10 minutes to paint [tex]40\frac{1}{2}[/tex] square feet of his bedroom wall.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Here, [tex]40\frac{1}{2}[/tex] square feet = 40.5 square feet

Rate at which he paints the wall =40.5/10

= 4.05 square feet per minute

As we know 1 hour =60 minutes

Now, number of square feet

The answer to this question which is based on Trignometry is that we divide when we want to calculate Trignometric Ratios

How many Trignometric ratios are available?

There are six basic trigonometric ratios: sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc). These ratios are used to calculate angles and sides of a right triangle.

Whenever we need to calculate Trignometric ratios we have to divide the length of 2 sides of a triangle and one more the Trignometric ratios can be only found in Right Angled triangle

Hence we can just find the Trignometric ratios for any Triangle we can only do it for right Triangles

The values of Trignometric ratios can be negative also and it depends on the angle for which we want to find the Trignometric ratios.

Answer: (6, -4)

Step-by-step explanation:

Because it translate right 4 units, so the x increase by 4, so x=6

It up 3, so y increase by 3, so y= -4

An equation in slope-intercept form of the line perpendicular to y = 2x-4

is y =(-1/2)x+10.

We are aware that there are many types of equations for lines, with the

general type being Ax+ By + C = 0, and the slope-intercept form equation

being y = mx + b.

m is the slope, and b is the y-intercept.

The y-intercept is the point (0,b) where the line intersects the y-axis when

x = 0, and the slope is the rate of change of the y-axis relative to the x-axis.

We are aware that the slopes of perpendicular lines are oppositely negative.

The slope of the given line, y = 2x-4, is 2.

Consequently, the given line will pass through point with a slope of (-1/2). (4,8).

∴8= (-1/2)(4)+b

8= -2+b

b = 10.

∴ y =(-1/2)x+10  is our required line.

The required radius of the cylindrical can is 4 millimeters.

A cylinder is a three-dimensional solid in mathematics that maintains, at a given distance, two parallel bases connected by a curving surface. These bases often have a circular form (like a circle), and a line segment known as the axis connects the centers of the two bases.

Given that,

The height of the cylinder h  = 12 cm.

And volume of the cylinder v = 600 mL

Since, 1 mL = cm³

The volume v = 600 cm³.

Let radius of cylinder is r,

To find the radius, use formula,

Volume of cylinder V = π x r² x h

22/7 x r² x 12 = 600

22/7 x r² = 50

r² = 350 / 22

r² = 15.909

r = 3.98

Answer:

55%

Step-by-step explanation:

first, you set up the problem as two fractions: 11 is to 20 as x is to 100. you cross multiply the 11 and 100, then divide that by 20 which gives you 55, which you divide by 100 for the percentage answer.

With linear inequalities in two variables, you still have y=mx+b and it still tells you the same thing.

The inequality portion adds two additional layers on top of the y=mx+b line.

If the inequality is > or <, then you draw the line as a dashed line.

If the inequality is ≥ or ≤, then you draw the line as a solid line.

The difference is that points on the > or < line do NOT make the inquality true, while points on the ≥ or ≤ line do.

The other piece is that all the points on one side of the line will also make the inequality true.

If you have "y>mx+b" or "y≥mx+b", then you shade above the line.

If you have "y<mx+b" or "y≤mx+b", then you shade below the line.

So there are three parts:

1. Where is the line?  

2. Is the line solid or dashed?

3. Do you shade above or below the line?

The number of small size and large size bowls of ice cream sold in the shop is 40 and 22 respectively.

let

Number of small bowl = x

Number of large bowl = y

x + y = 63

2.25x + 3y = 159

From (1)

x = 63 - y

Substitute into (2)

2.25x + 3y = 159

2.25(63 - y) + 3y = 159

141.75 - 2.25y + 3y = 159

- 2.25y + 3y = 159 - 141.75

0.75y = 17.25

divide both sides by 0.75

y = 17.25 / 0.75

y = 23

Substitute y = 23 into (1)

x + y = 63

x + 23 = 63

subtract 23 from both sides

x = 63 - 23

Answer:

22 rabbits and 50 hens

Step-by-step explanation:

Let H and R stand for the numbers of Hens and Rabbits.  Each hen has two feet and each rabbit has four feet.  Each only has 1 head.

We can set the quantities of feet and heads:

Hens:  2H feet and 1H heads

Rabbits:  4R feet and 1R heads

We are told that:

1.)  "The number of feet of the hens exceeds the number of feet of the rabbits by 12"  Rewrite this as an expression:

  2H - 4R = 12  [feet]

2)  "while the number of heads of the hens exceeds the number of the heads of the rabbits by 28"  This is written as:

  1H = 1R + 28  [heads]

Since each critter only has one head, this last expression will tell us, quickly, how many more Hens there are, which is 28.  But by substituting the first expression (the feet) into the second, we can detrermine the exact number of each animal.

Rearrange 2H - 4R = 12 to isolate one of the variables.  I'll choose H:

  2H - 4R = 12

  2H  = 12 + 4R

  H  = (12 + 4R)/2

   H =  6+2R

Now use this definition of H in the second equation:

1H = 1R + 28

1(6+2R) = 1R + 28

6 + 2R = 1R + 28

 R = 22   There are 22 rabbits

Use this in the second equation to find the number of hens:

1H = 1R + 28

1H = 22 + 28

 H = 50  There are 50 hens.

=================

Check:

1.)  "The number of feet of the hens exceeds the number of feet of the rabbits by 12."  

 Hens have 100 feet total.  Rabbits have 88 feet.    The hens have 12 more total feet:  This checks

2.)  "while the number of heads of the hens exceeds the number of the heads of the rabbits by 28"  

 There are 50 heans and 22 rabbits.  The number of hen heads exceed the number of rabbit heads by 28.  This also checks.
