Answer:

  15 Y (girls) in the room

Step-by-step explanation:

Given an initial ratio of boys : girls = 6 : 5 that becomes 1 : 1 when 3 boys leave the room, you want to know the number of girls in the room.

The initial difference in the number of ratio units is 6 -5 = 1. Removing 1 ratio unit from the "boys" side makes the ratio 5 : 5 = 1 : 1.

So, that 1 ratio unit corresponds to 3 boys. There are 5 ratio units of girls, so 3·5 = 15 girls.

There are 15 girls (Y) in the room.

__

Alternative solution

You could write an equation or two:

  b/g = 6/5 . . . . . . initial ratio of boys/girls

  (b-3)/g = 1/1 . . . . final ratio of boys/girls

Solving the first for b gives

  b = 6/5g

Using that in the second gives ...

  (6/5g -3) = g . . . . . . substitute for b, multiply by g

  1/5g = 3 . . . . . . . . add 3-g

  g = 15 . . . . . . . multiply by 5

Part A: annual gross salary =  $51,200. Part B:  income tax= $46,080

Part C: annual income, after tax reduction =  $46,080.

Part D: fortnightly net income  $126.24 per day.

Before taxes, benefits, and other wage garnishments are taken out of an employee's paycheck, that amount is known as their gross pay. Net pay, often known as take-home pay, is the amount that is left after all withholdings have been taken into account.

Given data:

Earning from shop clerk - $50,000 per year.

Earning from gardening - $1,200 per year.

Part A: annual gross salary.

annual gross salary =  $50,000 +  $1,200

annual gross salary =  $51,200

Part B:  income tax.

income tax = 10% of gross income

income tax = 0.10 * 51,200

income tax = $5,120

Part C: annual income, after tax reduction:

Net income = Gross income - tax

Net income = 51,200 - 5,120

Net income = $46,080

Part D: fortnightly net income:

fortnightly net income = Total net income / 365 days

fortnightly net income = $46,080 / 365

fortnightly net income = $126.24 per day.

The independent variable is the number of snacks purchased, denoted by "s", and the dependent variable is the total cost, denoted by "$". The relationship is linear, with $ = 3s + 15.

A rate is a measure of the amount of change of one quantity with respect to another quantity, often expressed as a ratio or a fraction. It tells us how much one quantity changes per unit of time or per unit of another quantity. Examples of rates include speed, velocity, acceleration, interest rate, and growth rate

In the given table, the independent variable is the number of snacks purchased, denoted by "s", and the dependent variable is the total cost, denoted by "$".

The relationship between the number of snacks purchased and the total cost is a linear relationship, where the total cost increases by $3 for every additional snack purchased.

We can write the equation for the relationship between the two variables as:

$ = 3s + 15

Here, the constant term 15 represents the fixed cost or the cost of buying zero snacks. The coefficient 3 of the independent variable "s" represents the additional cost incurred for each additional snack purchased.

Therefore, The independent variable is the number of snacks purchased, denoted by "s", and the dependent variable is the total cost, denoted by "$". The relationship is linear, with $ = 3s + 15.

The rate of change between 75 and 125 miles is calculated by dividing the difference between the fuel cost at 125 and 75 miles by the distance traveled. The fuel cost at 75 miles is $3.85, while the fuel cost at 125 is $6.35. The rate of change is $0.05 per mile.

To calculate the rate of change between 75 and 125 miles, subtract the fuel cost at 125 miles from the fuel cost at 75 miles and divide the difference by the distance travelled:

Rate of change = (fuel cost at 125 miles - fuel cost at 75 miles) / (125 - 75)

First, we need to find the fuel cost at 75 miles:

() = 0.1 + 0.05x

() = 0.1 + 0.05(75)

() = 3.85

The fuel cost at 75 miles is $3.85.

Next, we need to find the fuel cost at 125 miles:

() = 0.1 + 0.05x

() = 0.1 + 0.05(125)

() = 6.35

The fuel cost at 125 miles is $6.35.

Now we can substitute these values into the rate of change formula:

Rate of change = (6.35 - 3.85) / (125 - 75)

Rate of change = 2.5 / 50

Rate of change = 0.05

Answer:

B is correct

Step-by-step explanation:

a) The numbers that can be decomposed in the form 2A + 1 are the ones that are odd when subtracted by 1 and then divided by 2. So, we can check each number to see if it satisfies this condition:

6: (6 - 1)/2 = 2.5 (not a natural number)

8: (8 - 1)/2 = 3.5 (not a natural number)

11: (11 - 1)/2 = 5

16: (16 - 1)/2 = 7.5 (not a natural number)

19: (19 - 1)/2 = 9

22: (22 - 1)/2 = 10.5 (not a natural number)

23: (23 - 1)/2 = 11

So, the three numbers that can be decomposed in the form 2A + 1 are 11, 19, and 23.

b) The numbers in part a) have in common that they are odd.

From greatest comparative advantage to least comparative advantage the list of toothpaste is Mint, Fresh, Sparkling, Bright White

To determine the comparative advantage of toothpaste companies in producing small tubes of toothpaste, we need to look at the opportunity cost of producing small tubes of toothpaste in terms of the production of large tubes of toothpaste. The company with the lowest opportunity cost of producing small tubes of toothpaste (i.e., the company that gives up the least amount of large tubes of toothpaste to produce small tubes of toothpaste) has the greatest comparative advantage in producing small tubes of toothpaste. We can calculate the opportunity cost by looking at the difference in the number of large tubes of toothpaste that each company could produce if they chose to produce only large tubes versus the number of large tubes they could produce if they chose to produce some small tubes as well.

So, using the data provided in the table, we can calculate the opportunity cost for each company as follows:

Sparkling:

Opportunity cost of producing small tubes of toothpaste = (200 large tubes/hour - 100 large tubes/hour) / 200 small tubes/hour = 0.5 large tubes per small tube

Bright White:

Opportunity cost of producing small tubes of toothpaste = (250 large tubes/hour - 100 large tubes/hour) / 250 small tubes/hour = 0.6 large tubes per small tube

Fresh:

Opportunity cost of producing small tubes of toothpaste = (250 large tubes/hour - 200 large tubes/hour) / 250 small tubes/hour = 0.2 large tubes per small tube

Mint:

Opportunity cost of producing small tubes of toothpaste = (150 large tubes/hour - 150 large tubes/hour) / 150 small tubes/hour = 0 large tubes per small tube

Therefore, the order of the companies from greatest comparative advantage to least comparative advantage in producing small tubes of toothpaste is: Mint, Fresh, Sparkling, Bright White

s = 31

t = 62

u = 17

w = 31

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

Explanation:

Inscribed angles w and s subtend the same arc that the inscribed angle 31 degrees is doing. Therefore, angle w = angle s = 31 degrees.

Inscribed angles that subtend the same arc will be equal in measure.

Similarly, the 17 degree angle and angle u both subtend the same arc. This must mean angle u = 17 degrees.

------------

Use the inscribed angle theorem to determine the central angle t

angle t = 2*(inscribed angle w)

angle t = 2*(31)

angle t = 62 degrees

The shaded region is below both lines, and the boundary line y = 2x - 1 is dashed because the inequality is strict. The solution can be described as: y < 5 - 3x and y < 2x - 1.

Inequality is a mathematical statement that compares two values or expressions. It uses symbols such as "<" (less than), ">" (greater than), "<=" (less than or equal to), ">=" (greater than or equal to), or "≠" (not equal to) to indicate the relationship between the two expressions. Inequalities are used to represent a range of possible values, rather than just a single value as in an equation.

Here,

We have the system of inequalities:

y + 3x < 5

2x - y > 1

To solve this system, we can start by isolating y in each inequality:

y < 5 - 3x

y < 2x - 1

Now we can graph each inequality on the coordinate plane and shade the region that satisfies both inequalities.

For the first inequality y < 5 - 3x, we can start by graphing the line y = 5 - 3x. This line has a y-intercept of 5 and a slope of -3. Since the inequality is y < 5 - 3x, we need to shade the region below the line.

For the second inequality y < 2x - 1, we can start by graphing the line y = 2x - 1. This line has a y-intercept of -1 and a slope of 2. Since the inequality is 2x - y > 1, we need to shade the region below the line.

The solution to the system is the region that is shaded by both inequalities. Here is a graph of the solution:

The length of the best that is with the contact of rim of the pulley is (5/18)π cm.

The shaded region is 10√5 - (5/18)π cm.

To find the length of the belt that is in contact with the rim of the pulley, we need to find the length of the arc of the circle with radius 5 cm that is between the points O and P.

The circumference of a circle with radius 5 cm is 2πr = 10π cm. So the fraction of the circle between O and P is 10/360 = 1/36 of the total circumference. Therefore, the length of the arc OP is (1/36) x 10π = (5/18)π cm.

To find the shaded region, we need to subtract the length of the belt in contact with the pulley from the length of the belt pulled to point P.

The belt pulled to point P is the hypotenuse of a right triangle with legs 5 cm (the radius of the pulley) and 10 cm (the distance from the center of the pulley to point P). Using the Pythagorean theorem, we can find the length of the belt pulled to point P:

h² = 5² + 10²

h² = 125

h = √125 = 5√5 cm

So the length of the belt pulled to point P is 2(5√5) = 10√5 cm.

Therefore, the length of the shaded region is 10√5 - (5/18)π cm. This is the length of the part of the belt that is not in contact with the pulley.

The statement which most closely summarizes the data is that about 80 necklaces have more than 28 beads. The solution has been obtained by using the standard deviation.

What is standard deviation?

The standard deviation measures how skewed the data are with respect to the mean. Data are said to be more densely grouped around the mean and more dispersed, respectively, when the standard deviation is low and large.

We are given that the mean for the normal distribution is 24 beads and the standard deviation is 4 beads.

Now,

⇒ P (X ≥ 28) = 1 - P (X < 28)

⇒ P (X ≥ 28) = 1 - P ([tex]\frac{X-24}{4}[/tex] < 1)

⇒ P (X ≥ 28) = 1 - P (Z < 1)

⇒ P (X ≥ 28) = 1 - 0.84

⇒ P (X ≥ 28) = 0.16

m/EFH = 109° and m/EFG = 18°. Angles in a straight line sum to 180°. Since m/GFH is 71°, the remaining angle measures must add up to the remaining 109°. Therefore, m/EFH must be 109° and m/EFG must be 18°.

To find m/EFH and m/EFG, we need to use the fact that angles in a straight line sum to 180°. We can use this fact to work out the missing angle measures.

First, we note that m/GFH is 71°. This means that the remaining angles must add up to the remaining 109°.

We can then calculate m/EFH by subtracting m/GFH from 180°. m/EFH is therefore 180° - 71° = 109°.

Next, we can calculate m/EFG by subtracting m/EFH from 180°. m/EFG is therefore 180° - 109° = 18°.

Therefore, m/EFH = 109° and m/EFG = 18°.

General characteristics of histograms ,based on some general observations are,

If the histogram is roughly symmetric around its center, then the distribution is likely to be approximately normal (bell-shaped).

If the histogram has a peak on one side and a long tail on the other, then the distribution is likely to be skewed (either positively or negatively skewed).

If the histogram has multiple peaks or modes, then the distribution is likely to be multimodal.

7/8 is greater than -0.50, greater than -15/16, and less than -1/4. All of these inequalities are true except for 7/8 being less than -0.60.

To solve the inequality 7/8 < -0.60, we need to manipulate it to get it in the form of an equation. First, we can multiply both sides of the inequality by 8, to get 7 < -8(0.60). Next, we can distribute the negative sign on the right side to get 7 < -4.80. Finally, we can subtract 7 from both sides of the equation to get 0 < -4.80 - 7, which equals 0 < -11.80. This means that 7/8 is not less than -0.60, which is the answer to the inequality.

To confirm this answer, we can also solve the inequality 7/8 > -0.50. Again, we can multiply both sides of the inequality by 8 to get 7 > -8(0.50). We can then distribute the negative sign to get 7 > -4. Now, if we subtract 7 from both sides of the equation, we get 0 > -4 - 7, which equals 0 > -11. This means that 7/8 is indeed greater than -0.50.

So, n(S) = 52

We know that there are 26 red cards in a standard deck of cards.

So, n(A) = 26

And there are 4 kings

So, n(B) = 4

Since there are two cards of king are red and two are black.

The favorable number of cards = 26+2

                                                 =28

So, the required probability is:

P = 28/52​

P = 7/13​
