Answer:

26

Step-by-step explanation:

Total pupils 60

32 boys and girls will be 28 (60-32)

Cola 12 boys

Water 4 boys 9 girls

Milk 21 pupils

Total results 12 + 4 +9+ 21 = 46

Outstanding girls will be 60 - 46

If 14 girls liked cola and 12 boys liked cola, total will be 14 + 12

Answer:

Multiplying the second equation by 2, we get:

4x + 6y = -20

Now we can subtract the first equation from this to eliminate x:

4x + 6y = -20

-(5x + 2y = -3)

-x + 4y = -17

Now we have one equation with only y. Solving for y:

-x + 4y = -17

4y = x - 17

y = (1/4)x - 17/4

Now we can substitute this expression for y into either equation to solve for x. Let's use the first equation:

5x + 2y = -3

5x + 2((1/4)x - 17/4) = -3

5x + (1/2)x - 17 = -3

(11/2)x = 14

x = 28/11

So the solution is (x,y) = (28/11, -17/11).

The conditional probability that a randomly chosen student studies every day, given that the student passes a math test is O P(M|S). The correct option is A.

P(M|S) is the probability that a randomly chosen student passes a math test given that the student studies every day. But, the question is asking for the probability that a student studies every day given that the student passes a math test.

Considering an P(M|S) situation,
Option D: P(SM) is incorrect because it means the probability that both events S and M occur simultaneously.
Option C: P(S) and P(M) is incorrect because it shows the probabilities of two individual events, not the probability of one event given that the other event has occurred.
Option B: P(M AND S) is incorrect because it means the probability that both events M and S occur simultaneously.

The given problem is based on Conditional Probability Notation to Describe Events. The notation used for conditional probability is P(A|B). Where A and B are two events, the notation represents the probability of event A occurring, given that event B has occurred. Conditional probability can be described as the probability of one event happening given that another event has already happened.

Step-by-step explanation:

If we call 1999 year 0, then 2010 would be year 11. This makes the coordinates for our problem (0, 43129) and (11, 56780). That means that the initial value, a, is 43129 and we can use that to solve for b.

[tex]56780=43129(b)^{11[/tex]

Divide both sides by 43129 to get

Answer: The farmer has 1377 sheeps.

Step-by-step explanation:

Farmer loses sheeps due to drought = 32½% of 2400

32½% of 2400

= 65 × 2400 × 1

2100

After cutting it will be,

65×12

=780

Number of sheeps that are left with him = 2400 - 780

=1620

After that,

The farmer loses due to sickness = 15% of 1620

15% of 1620

= 15 × 1620

100

After cutting it will be,

3 × 81

= 243

Total amount of sheeps that the farmer loses = 780 + 243

= 1023

Now the number of sheeps he has is 2400-1023

= 1377

Answer: Three sides of a right triangle are the lengths of its legs and the length of its hypotenuse.

To know that three given sides will create a right triangle, we can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the legs. Symbolically, if a, b, and c are the lengths of the sides of a right triangle, with c being the hypotenuse, then:

c^2 = a^2 + b^2

Therefore, if we are given the lengths of three sides, we can square the lengths of the legs, add them together, and then take the square root to find the length of the hypotenuse. We can then compare the squared length of the hypotenuse to the sum of the squares of the legs. If they are equal, the three sides form a right triangle. If the squared length of the hypotenuse is greater than the sum of the squares of the legs, the three sides form an obtuse triangle. If the squared length of the hypotenuse is less than the sum of the squares of the legs, the three sides form an acute triangle.

[tex]90^{0} - 32^{0} = 58^{0}[/tex]

1 = 4 = 90°

2 = 32°

3 = 5 = 58°

Answer:

Step-by-step explanation:

You want the measures of the marked angles in the rectangle, given one of the acute angles is 32°.

The corner angles of a rectangle are all 90°. That's part of the definition of a rectangle:

  ∠1 = ∠4 = 90°

That make angles 5 and 32° be complementary angles:

  ∠5 = 90° -32° = 58°

The angles at the opposite end of the diagonal are complementary to these, as the sum of angles in a triangle is 180°.

  ∠2 = 90° -58° = 32°

  ∠3 = 90° -32° = 58°

__

Additional comment

You may have noticed that angles on opposite sides and opposite ends of the diagonal have the same measure. This is no coincidence. These are called "alternate interior angles". As such, they are always congruent where a diagonal meets parallel lines. (The sides of a rectangle are parallel.)

Accοrding tο the angle sum prοperty οf a triangle, m∠1 + m∠2 + m∠3 = 180° and m∠3 + m∠4 + m∠5 = 180° these twο equatiοns can be used tο find m∠3.

The angle sum prοperty οf a triangle is a fundamental geοmetric prοperty that states that the sum οf the interiοr angles οf a triangle is always equal tο 180°. In οther wοrds, fοr any triangle, the sum οf the measures οf its three interiοr angles is always 180°.

This prοperty hοlds true fοr all triangles, regardless οf their size οr shape. It is an impοrtant cοncept in geοmetry and is used in variοus prοοfs and calculatiοns invοlving triangles.

One cοmmοn applicatiοn οf the angle sum prοperty οf a triangle is tο find the measure οf an unknοwn angle in a triangle if the measures οf the οther twο angles are knοwn. This can be dοne by subtracting the sum οf the knοwn angles frοm 180°.

The twο equatiοns that can be used tο find the measure οf angle 3 (m∠3) if the measures οf the οther angles are knοwn are:

m∠1 + m∠2 + m∠3 = 180°

This equatiοn can be used if the measures οf angles 1 and 2 are knοwn. We can find the measure οf angle 3 by subtracting the sum οf angles 1 and 2 frοm 180°.

m∠3 + m∠4 + m∠5 = 180°

This equatiοn can be used if the measures οf angles 4 and 5 are knοwn. We can find the measure οf angle 3 by subtracting the sum οf angles 4 and 5 frοm 180°.

Thus, m∠1 + m∠2 + m∠3 = 180° and m∠3 + m∠4 + m∠5 = 180° these twο equatiοns can be used tο find m∠3.

The amount repaid in the three months of the loan amount $24,000 with a condition of 20% repayment is equal to $11,712.

Percent of amount Maricarmen has to pay = 20% of the loan each month.

This implies  Maricarmen pay 0.2 times the loan amount each month.

Amount Maricarmen will pay in the first month is equal to,

0.2 x $24,000 = $4,800

Amount left after the first payment,

$24,000 - $4,800 = $19,200

In the second month, Maricarmen will pay,

0.2 x $19,200 = $3,840

Amount left after the second payment,

$19,200 - $3,840 = $15,360

In the third month, Maricarmen will pay,

0.2 x $15,360 = $3,072

Amount left after the third payment,

$15,360 - $3,072 = $12,288

Handy should produce 5400 units of C1 and 5600 units of C2 and the production plan should remain the same, with 5400 units of C1 and 5600 units of C2 being produced.

1. To develop a production plan for Handy, we need to calculate the expected demand for each component under each scenario. This is done by multiplying the demand for each scooter by the number of components used in its production, and then multiplying by the probability of each scenario occurring.

Expected demand for C1 = (600 x 6 x 0.3) + (400 x 6 x 0.4) + (300 x 6 x 0.3) + (200 x 10 x 0.3) + (400 x 10 x 0.4) + (500 x 10 x 0.3) = 5400

Expected demand for C2 = (600 x 10 x 0.3) + (400 x 10 x 0.4) + (300 x 10 x 0.3) + (200 x 4 x 0.3) + (400 x 4 x 0.4) + (500 x 4 x 0.3) = 5600

Therefore, Handy should produce 5400 units of C1 and 5600 units of C2.

2. To determine whether Handy should retool its production system to develop C3, we need to compare the expected cost of production with and without the new component.

Without C3:

Expected cost = (5400 x $8) + (5600 x $12) = $43,200 + $67,200 = $110,400

With C3:

Expected cost = (5400 x $14) + (5600 x $14) = $75,600 + $78,400 = $154,000

Since the expected cost of production with C3 is higher than without C3, Handy should not retool its production system to develop the new component. The production plan should remain the same, with 5400 units of C1 and 5600 units of C2 being produced.

The area of the parallelogram is 630.4 square units, to the nearest tenth.

Step-by-step explanation:

The formula to find the area of a parallelogram is:

[tex]A=bh[/tex]

where b is the base and h is the height.

For the given parallelogram ABCD, BC and AD are the bases and h is the height. Therefore, we need to calculate the height, h, before we can calculate the area of the parallelogram.

The height of the parallelogram is also the side opposite angle 62° in the right triangle of the given diagram. As we also know the hypotenuse of this triangle, we can use the sine trigonometric ratio to find "h".

[tex]\boxed{\begin{minipage}{9 cm}\underline{Sine trigonometric ratio} \\\\$\sf \sin(\theta)=\dfrac{O}{H}$\\\\where:\\ \phantom{ww}$\bullet$ $\theta$ is the angle. \\ \phantom{ww}$\bullet$ $\sf O$ is the side opposite the angle. \\\phantom{ww}$\bullet$ $\sf H$ is the hypotenuse (the side opposite the right angle). \\\end{minipage}}[/tex]

Given:

Therefore, the expression for h is:

About 1.5% of American women have shoe sizes that are at least 11.3, using the empirical rule and a standard normal distribution table.

To use the empirical rule, we assume that the shoe sizes follow a normal distribution. We can then convert the shoe size 11.3 to a z-score using the formula:

z = (x - μ) / σ

where x is the shoe size, μ is the mean, and σ is the standard deviation. Plugging in the values, we get:

[tex]z = (11.3 - 8.11) / 1.46 = 2.17[/tex]

This tells us that a shoe size of 11.3 is 2.17 standard deviations above the mean.

The empirical rule enables us to determine that, with a normal distribution:

About 68% of the data falls within one standard deviation of the mean

The data is within two standard deviations of the mean for about 95% of the time

About 99.7% of the data falls within three standard deviations of the mean

Since 11.3 is more than two standard deviations above the mean, we know that fewer than 5% of women will have a shoe size this large. To find the exact percentage, we can use a standard normal distribution table (also known as a z-table) or a calculator to find the area under the curve to the right of z = 2.17.

Using a calculator or a table, we find that the area to the right of z = 2.17 is approximately 0.015, or 1.5%. Therefore, we can say that about 1.5% of American women have shoe sizes that are at least 11.3.

Without more information about the specific survey and population being surveyed, it is difficult to provide a precise answer to this question. However, I can provide some general information on how probabilities can be calculated in surveys.

Assuming that the survey is a representative sample of college students and that the question about difficulty falling asleep is a binary (yes/no) question, we can calculate the probability of a surveyed college student having a hard time falling asleep on 3 or more days in the last week as follows:

1. Determine the total number of surveyed college students who answered the question about difficulty falling asleep.

2. Determine the number of surveyed college students who reported having a hard time falling asleep on 3 or more days in the last week.

3. Divide the number of surveyed college students who reported having a hard time falling asleep on 3 or more days in the last week by the total number of surveyed college students who answered the question about difficulty falling asleep.

For example, if 1,000 college students were surveyed and 800 of them answered the question about difficulty falling asleep, and 200 of those 800 reported having a hard time falling asleep on 3 or more days in the last week, then the probability of a surveyed college student having a hard time falling asleep on 3 or more days in the last week would be 200/800, or 0.25, or 25%.

To find the Maclaurin series for $f(x) = xe^x$, we can use the formula for the Maclaurin series of $e^x$ and differentiate the product term by term:

$$e^x = \sum_{n=0}^\infty \frac{x^n}{n!}$$

$$xe^x = x \sum_{n=0}^\infty \frac{x^n}{n!} = \sum_{n=0}^\infty \frac{x^{n+1}}{n!}$$

So the first few terms of the Maclaurin series for $f(x)$ are:

$$f(x) = xe^x = x + x^2 + \frac{x^3}{2} + \frac{x^4}{3} + \frac{x^5}{24} + \cdots$$

To find the radius of convergence, we can use the ratio test:

$$\lim_{n\to\infty} \left| \frac{a_{n+1}}{a_n} \right| = \lim_{n\to\infty} \left| \frac{x^{n+2}/(n+1)!}{x^{n+1}/n!} \right| = \lim_{n\to\infty} \frac{|x|}{n+1} = 0$$

Since the limit is less than 1 for all values of $x$, the Maclaurin series converges for all values of $x$, and the radius of convergence is infinite.
