The number of boxes that should be opened to find it is 98 boxes.

Probability simply means the likelihood of the occurence of an event.

When there is a 3 percent chance or finding something special in a box,the number of boxes that will be opened will be illustrated thus:

Let the number of boxes be 100.

Therefore, the number of boxes will be:

= Total boxes - Percentage given

= 100 - 3

= 97

In this case, the 98th box will give the person the chance of getting it.

The ratio of boys to girls in the 9th grade is 7 : 9. Girls are 218

proportion of girls in total students are [tex]\frac{218}{9}[/tex] = 24.2

According to the question, given that

In class ratio of boys and girls is 7 : 9

and girls in the class are 218

Proportion of girls in total class = [tex]\frac{218}{9}[/tex]

                                                    = 24.2

Therefore, we get proportion of girls in the class is 24.2

When determining if two ratios or fractions are equivalent, the proportion formula is utilized. The proportional formula is as follows:

a : b :: c : d = a/b = c/d

Proportion Formula

a:b::c:d = a/b = c/d

where,

a, d = Extreme terms

b, c = Mean terms

The product of means equals the product of extremes is one of the various proportional formulas. You can write this as ad = bc.

Two additional proportional formulas that depend on direct or indirect variation are available. When two quantities x and y are in direct proportion, y = k x, and when x and y  are in indirect proportion, y = k/x, with k serving as the proportionality constant in both cases.

The length of the missing side z would be 17 units which is determined by Pythagoras's theorem.

A right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

According to Pythagoras's theorem,

⇒ a² + b² = c²

Here, a = 8  b = 15 and c = z

⇒ (8)² + (15)² = z²

⇒ 64 + 225 = z²

Apply the addition operation,

⇒ 289 = z²

⇒ z² = 289

⇒ z = √289

⇒ z = 17

Therefore, the length of the missing side z would be 17 units.

Each label should be dragged to the correct location in the equation as follows:

100 yards/1 × (3) feet/1 yards × (12) inch/1 foot × (2.54) cm/1 inch × 1 (meter)/100 cm = (91.44) meter

A conversion factor can be defined as a number that is typically used to convert (change) a number in one (1) set of units to another, either by dividing or multiplying.

Generally speaking, an appropriate conversion factor to an equal value must be used when it is necessary to perform any mathematical conversion.

Conversion:

1 yard = 0.9144 meter

100 yards = X meters

Cross-multiplying, we have:

X = 0.9144 × 100

The  system of equations that could be used to determine the price of each pound of raspberries and the price of each pound of grapes is:  44 x + 43 y = 217 , 45x + 18y = 144 .  Each pound of peaches cost $2 and each pound of grapes cost $3

x = price of each pound of peaches

y = price of each pound of grapes.

Given that yesterday,  he sold 44 pounds of peaches and 43 pounds of grapes for a total revenue of $217

So 44 x + 43 y = 217 be equation 1.

Also given that today he sold 45 pounds of peaches and 18 pounds of grapes for a total revenue of $144.

So 45x + 18y = 144 equation 2.

Multiplying equation 1 with 18 gives us,

792x +774y = 3906

Multiplying equation 2 with 43 gives us,  

1935x+774y = 6192

Solving these,

792x +774y = 3906

1935x+774y = 6192

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

-1143 x=- 2286

x = 2286/ 1143

x = 2

Plug this value of x in equation 1 and solve for y, to get,

44 x + 43 y = 217

44 (2) + 43 y = 217

43 y = 217 − 88

43 y =129

y = 129/43

y = 3

Given that,

In the picture there is a straight line which has a point where the 2 lines intersect.

The angles are 90° and 30°.

We have to find the angle a.

A straight angle in geometry is an angle with a vertex point that is at 180 degrees. In essence, it creates a straight line with sides that face away from the vertex. "Flat angles" is another name for it.

So, we get,

90°+30°+a=180°

a=180°-90°-30°

a=180°-120°

a=60°

Based on the distance of the race and the length of the sections, the number of people that Heather will need to be on her team are 26 people

The entire race has a length of 5 1/5 miles and this length will be divided into sections that are 1/5 miles long.

Only one member of the team can run in each of these sections so enough people are needed on Heather's team to run the 1/5 mile sections.

The number of people to be in a team can be found by the formula:
= Length of race / Length of sections

= 5 1/5 miles / (1/5)

Explanation:

To answer this question, we use an example.

Given the pre-image:

• A square with side length 1 cm

• Perimeter = 4 x 1 = 4cm

If the square is dilated by a scale factor of 4:

• Side length = 4cm

• Perimeter = 4 x 4 =16cm

We see therefore that 'The perimeter of the image is 4 times as large as the perimeter of the pre-image.'

1: Each observation should be independent, it must not depend on the result of previous observation.

2: The probability of success should stay same from trial to trial.

3: n is fixed (the number of observations)

4: There are only two outcomes success or failure.

Loretta would not have paid any taxes last year because her total earnings were below the €8625 threshold.

What is Percentage ?

A Percentage is a figure or ratio that is stated as a fraction of 100 in mathematics. Although the abbreviations "pct.", "pct.", and occasionally "pc" are also used, the percent symbol, "%," is frequently used to indicate it. A % is a number without dimensions and without a measurement system.

The total amount paid in tax from Cary's last year earning is £9640
Total earning last year = €34 500

Tax on earnings :
First €3500 = 0%
€3500 to €10 500 = 25%
Earnings above €10 500 = 35%
Therefore, tax paid on €34 500 :

Tax percentage × amount earned

First €10 500 earned = (25% × 10,500) = 2625

Excess above €10 500 = (34500 - 10500) = 24000

25% × 24000 = 6000

Therefore, the total tax amount = €(2625 + 6000) = €8625

A quadrilateral with at least one pair of parallel sides is called, in American and Canadian English, a trapezoid. In British and other forms of English, a (North American) trapezoid is called a trapezium. The transposition of these two terms was a result of an error in Charles Hutton's mathematical dictionary.

In Euclidean geometry, a trapezoid is a convex quadrilateral by definition. The bases of the trapezoid are the parallel sides. If the remaining two sides are parallel, they are referred to as the legs (or lateral sides); if not, the trapezoid is a parallelogram, and there are two pairs of bases. As opposed to the particular examples below, a scalene trapezoid is a trapezoid without equal sides.

The Greek mathematician Euclid identified five different quadrilateral shapes, of which four had two sets of parallel sides (the square, rectangle, rhombus, and rhomboid in English) and one did not (a trapezia, meaning "a table," which comes from "four" and means "a foot; end, boundary, edge").

In his commentary on the first book of Euclid's Elements, Proclus (412–485) developed two varieties of trapezia: one pair of parallel sides, or a trapezium (v), divided into isosceles (equal legs), and scalene (unequal) Similar to how cuboid and rhomboid both mean "resembles," trapezia with no parallel sides is a trapezoid, trapezoeidé, or literally "trapezium-like."

English followed Proclus's arrangement until the late 18th century, when a prominent mathematical lexicon produced by Charles Hutton in 1795 endorsed a transposition of the terms without providing an explanation. Although this error was fixed in British English around 1875, it remained in American English till the present..

The inequality expression given as 2 - |6 + 12x| > -28 has a solution of -3 < x < 2

From the question, the inequality is given as

2-|6+12x|>-28

Rewrite properly as

2 - |6 + 12x| > -28

Subtract 2 from both sides

- |6 + 12x| > -30

Divide both sides by -1

|6 + 12x| < 30

Remove the absolute bracket

So, we have the following representation

-30 < 6 + 12x < 30

Add -6 to all sides of the inequality

So, we have

-36 < 12x < 24

Multiply through by 1/12

So, we have
