Step-by-step explanation:

Set up a proportion to find how many total students there are [notice how females are on top and totals are on the bottom of the ratios]

\(\frac{4}{9}\) = \(\frac{396}{x}\) so cross multiply 4x = 396(9) so x = 891, if there are a total of 891 students and you need 1 teacher per 11 students then take 891/11 so you need 81 teachers.

You could set up another proportion 1/11 = x/891

If there are 396 female students, there are 81 teachers.

Suppose the  real measurements were "a" and "b"

Then their ratio will be formed as

\(\dfrac{a}{b} = \dfrac{p \times x}{q \times x} = \dfrac{p}{q}\)

where  is a common factor (not 1)

This shows that to get the real measurements from the given ratio, we need to assume to have some factor possibly cancelled from both the numerator and the denominator.

Thus, a = px, b = qx

First, Set up a proportion to find how many total students there are

[notice how females are on top and totals are on the bottom of the ratios]

So, 4/9 = 396 / x

then, cross multiply

4x = 396(9)

so x = 891,

if there are a total of 891 students and we need 1 teacher per 11 students then take 891/11.

Thus, you need 81 teachers.

Also, we could set up another proportion 1/11 = x/891

Hence,  If there are 396 female students, there are 81 teachers.

The minimum possible probability that chip A is defective can be calculated using conditional probability. Given that chips (A, B) and (A, C) are tested defective, the minimum possible probability that chip A is defective is 1/3.

Let's consider the different possibilities for the status of chips A, B, and C.

Case 1: Chip A is defective.

In this case, both (A, B) and (A, C) are tested defective as stated in the problem.

Case 2: Chip B is defective.

In this case, (A, B) is tested defective, but (A, C) is not tested defective.

Case 3: Chip C is defective.

In this case, (A, C) is tested defective, but (A, B) is not tested defective.

Case 4: Neither chip A, B, nor C is defective.

In this case, neither (A, B) nor (A, C) are tested defective.

From the given information, we know that at least one of the pairs (A, B) and (A, C) is tested defective. Therefore, we can eliminate Case 4, as it contradicts the given data.

Among the remaining cases (Case 1, Case 2, and Case 3), only Case 1 satisfies the condition where both (A, B) and (A, C) are tested defective.

Hence, the minimum possible probability that chip A is defective is the probability of Case 1 occurring, which is 1/3.

Step-by-step explanation:

*the box plots are shown in the attachment below.

Answer:

The median hours spent in the weight room for school 1 is less than the median for school 2 and the interquartile ranges for both.

Step-by-step explanation:

Median on a box plot is depicted by the vertical line that divides the rectangular box into 2.

The median hours for school 1 = 8

The median hours for school = 9

Interquartile range on a box plot is the range of the rectangular box.

Interquartile range for school 1 = 10 - 4 = 6

Interquartile range for school 2 = 12 - 6 = 6

Therefore, it is true that the median hours spent by school 1 (8 hrs) is less than the median hours spent by school 2 (9 hours).

It is also true that the jnterquartile range for school 1 and school tok are also equal (6).

The surface area she needs for the door is 33680 cm² or 3.368 m².

Surface area = 2(hw + ht + wt)

where:

h is the height οf the dοοr

w is the width οf the dοοr

t is the thickness οf the dοοr

Tο find the surface area οf a dοοr, yοu need tο measure the height, width, and thickness οf the dοοr and multiply thοse values tοgether. Assuming that the dοοr is rectangular we can use, surface area = 2(hw + ht + wt).

The first term in the fοrmula (hw) represents the area οf the frοnt οr back οf the dοοr, while the secοnd term (ht) represents the area οf the twο sides οf the dοοr and the third term (wt) represents the area οf tοp and bοttοm οf the dοοr. Once she has the surface area, she can calculate hοw much paint she needs tο buy based οn the cοverage rate οf the paint she has chοsen.

Given the data,

h = 200 cm

w = 80 cm

t = 3

Substitute the data in formula

2(hw + ht + wt)

⇒ 2(200·80 + 200·3 + 80·3)

⇒ 2(16000 + 600 + 240)

⇒ 2(16840)

⇒ 33680

Thus, the surface area she needs for the door is 33680 cm² or 3.368 m².

The amount collect by each persons,

Lia = 37.5 dollars

Phil = 50.3 dollars

Cam = 112.5 dollars

We have,

Lia ,Phil ,and cam collect a total of 200. 30 dollars.

And, Phil collects 12. 80 more than Lia. Cam collects 3 times as much as Lia.

Let us assume that,

Lia collect the amount = x

Hence, For Phil = 12.80 + x

For Cam = 3x

So, We get;

x + (12.80 + x) + 3x = 200.2

Solve for x,

5x + 12.80 = 200.3

5x = 200.3 - 12.8

5x = 187.5

x = 187.5 / 5

x = 37.5 dollars

Therefore, The amount collect by each persons,

One of the four fundamental arithmetic operations, or how numbers are joined to create new numbers, is division. The other operations are multiplication, addition, and subtraction. Division in mathematics is the process of dividing an amount into equal pieces. For instance, we may split a group of 20 people into four groups of 5, five groups of 4, and so on. In mathematics, division is the process of dividing a number into equal parts and calculating the maximum number of equal parts that may be formed. For instance, dividing 15 by 3 results in the division of 15 into 3 groups of 5 each. The division sign, "÷" or occasionally "/," is used in computer code.

Here,

1 inch has 2.54 cm

x inch has 2.70 inch,

1/2.54=x/2.7

x=2.7/2.54

x=1.063 inch

If a segment is 2. 7 centimeters long, it is 1.063 inch when there are about 2. 54 centimeters in 1 inch.

Answer:

The measure of the indicated exterior angle is 110°

Step-by-step explanation:

Let us revise the rule of the exterior angle

In a triangle, the measure of an exterior angle at a vertex of the triangle equals the sum of the measures of the two opposite interior angles to this vertex.

We will use this rule to solve the question

∵ The ladder, the house, and the ground formed a right triangle

∵ The ladder's angle with the ground facing away from the house is

   an exterior angle of the triangle

∵ The angles of measures 90° and 20° are its opposite interior angles

→ By using the rule above

∴ The measure of the exterior angle = 90° + 20°

∴ The measure of the exterior angle = 110°

∴ The measure of the ladder's angle with the ground facing away

   from the house is 110°

∴ The measure of the indicated exterior angle is 110°

A regular polygon with angles that all measure 162 degrees has 20 sides.

Let's first consider a formula to find the measure of an interior angle of a regular polygon. We can use the formula:

Interior angle = (n-2) x 180 / n,

where n is the number of sides of the polygon.

If all angles of the polygon measure 162 degrees, then we can set up an equation:

(n-2) x 180 / n = 162

Multiplying both sides by n, we get:

(n-2) x 180 = 162n

Expanding the left side, we get:

180n - 360 = 162n

Subtracting 162n from both sides, we get:

18n - 360 = 0

Adding 360 to both sides, we get:

18n = 360

Dividing both sides by 18, we get:

n = 20

The difference between the height (h) and the slant height (L) of the pyramid is that the height measures the vertical distance from the apex to the base, while the slant height measures the length along the surface of the pyramid from the apex to any point on the base's edge.

The height (h) of a pyramid refers to the perpendicular distance between its base and its apex. It is the vertical measurement from the highest point of the pyramid to the base. In the given context, the specific value of the height (h) is not provided, so we cannot determine its exact value.

On the other hand, the slant height (L) of a pyramid refers to the length of the line segment that connects the apex of the pyramid to any point on the edge of its base. The slant height is measured along the surface of the pyramid, forming an inclined line from the apex to the base. In this case, the slant height is given as 10.50 units.

Therefore, the difference between the height (h) and the slant height (L) of the pyramid is that the height measures the vertical distance from the apex to the base, while the slant height measures the length along the surface of the pyramid from the apex to any point on the base's edge.
