By solving equations we know that there are 30 giraffes and 40 ostriches in the zoo.

A mathematical statement known as an equation is made up of two expressions joined by the equal sign.

A formula would be 3x - 5 = 16, for instance.

When this equation is solved, we discover that the number of the variable x is 7.

So, calculate as follows:

Let g represent giraffes and o represent ostriches.

g + o = 70 ...(1)

4*g + 2*o = 200  ...(2)

g = 70 - o, according to equation 1, therefore we may enter that number in place of g in equation 2 to obtain:

4*g + 2*o = 200

4*(70-o) + 2*o = 200

280 - 4o + 2o = 200

-2o = 200 - 280

2o = 80

o = 80/2

o = 40

Ostriches are 40 then giraffes will be:

70 - 40 = 30

Therefore, by solving equations we know that there are 30 giraffes and 40 ostriches in the zoo.

There are approximately 0.976 grams of carbon (C) in the given sample of the carbohydrate (C9H11O6).

To find the number of grams of carbon (C) in the sample, we need to first determine the molar mass of the carbohydrate.

The molar mass of C is approximately 12.01 g/mol. The molar mass of H is approximately 1.01 g/mol, and the molar mass of O is approximately 16.00 g/mol.

The molar mass of the carbohydrate (C9H11O6) can be calculated as follows:

(9 * 12.01 g/mol) + (11 * 1.01 g/mol) + (6 * 16.00 g/mol) = 162.18 g/mol

Next, we can use the Avogadro's number (6.022 x 10^23) to determine the number of moles in the sample:

4.9 x 10^22 molecules / 6.022 x 10^23 molecules/mol = 0.0813 mol

Finally, we can calculate the mass of carbon in the sample by multiplying the number of moles by the molar mass of carbon:

0.0813 mol * 12.01 g/mol ≈ 0.976 g

So, there are approximately 0.976 grams of carbon in this sample.
There are approximately 0.976 grams of carbon (C) in the given sample of the carbohydrate (C9H11O6).

To find the mass of carbon in the sample, we first need to determine the molar mass of the carbohydrate. The molar mass of an element or compound is the mass of one mole of that substance. In this case, we have the formula C9H11O6, which indicates that the carbohydrate consists of 9 carbon atoms (C), 11 hydrogen atoms (H), and 6 oxygen atoms (O).

The molar mass of carbon is approximately 12.01 g/mol, hydrogen is approximately 1.01 g/mol, and oxygen is approximately 16.00 g/mol. To calculate the molar mass of the carbohydrate, we multiply the number of atoms of each element by their respective molar masses and sum them up.

Therefore, the molar mass of C9H11O6 is

(9 * 12.01 g/mol) + (11 * 1.01 g/mol) + (6 * 16.00 g/mol) = 162.18 g/mol.

Next, we can use the Avogadro's number (6.022 x 10²³) to determine the number of moles in the given sample. The given sample contains 4.9 x 10²²molecules of the carbohydrate. Dividing this by Avogadro's number gives us the number of moles:

4.9 x 10 molecules / 6.022 x 10^23 molecules/mol = 0.0813 mol.

Finally, we can calculate the mass of carbon in the sample by multiplying the number of moles by the molar mass of carbon: 0.0813 mol * 12.01 g/mol ≈ 0.976 g. Therefore, there are approximately 0.976 grams of carbon in the given sample.

In conclusion, the sample of the carbohydrate (C9H11O6) contains approximately 0.976 grams of carbon (C).

Step-by-step explanation:

To solve this problem, we need to first determine the dimensions of the box after the squares have been cut and the sides folded up. Let's call the length of the square side x. From the diagram, we can see that the length of the box will be 12 - 2x, and the width will also be 12 - 2x. The height of the box will be x.

To find the volume of the box, we multiply these dimensions together:
V = (12 - 2x)(12 - 2x)(x)

Expanding this expression, we get:
V = 4x^3 - 48x^2 + 144x

Now we need to find the maximum volume. We can do this by finding the value of x that makes the derivative of V (dV/dx) equal to zero:

dV/dx = 12x^2 - 96x + 144
Setting this equal to zero and solving for x, we get:

x = 2 cm or x = 6 cm

We can discard the solution x = 2 cm, because if we plug it back into the original equation for V, we get a volume of zero (since the height of the box would be zero).

So the optimal value of x is x = 6 cm. Plugging this back into the expression for the volume, we get:

V = 4(6)^3 - 48(6)^2 + 144(6) = 864 cm^3

Therefore, the dimensions of the finished box are:

Length = 12 - 2x = 12 - 2(6) = 0 cm (invalid)

Width = 12 - 2x = 12 - 2(6) = 0 cm (invalid)

Height = x = 6 cm

c. The probability that at least 27 of them live in cities with a population greater than 100,000 people is approximately 0.896.

d. The probability that between 22 and 28 (including 22 and 28) of them live in cities with a population greater than 100,000 people is approximately 0.164.

To solve this problem, we can use the binomial probability formula. Let's define "success" as an American living in a city with a population greater than 100,000 people, and "failure" as an American living in a city with a population less than or equal to 100,000 people. The probability of success is given as 0.75 (75%).

a. To find the probability that exactly 28 of them live in cities with a population greater than 100,000 people, we use the formula: P(X = 28) = (37 choose 28) * (0.75^28) * (0.25^9). Evaluating this expression, we find that the probability is approximately 0.058.

b. To find the probability that at most 28 of them live in cities with a population greater than 100,000 people, we sum up the probabilities for all values from 0 to 28. P(X ≤ 28) = Σ[P(X = k)] for k = 0 to 28. Evaluating this expression, we find that the probability is approximately 0.091.

c. To find the probability that at least 27 of them live in cities with a population greater than 100,000 people, we sum up the probabilities for all values from 27 to 37. P(X ≥ 27) = Σ[P(X = k)] for k = 27 to 37. Evaluating this expression, we find that the probability is approximately 0.896.

d. To find the probability that between 22 and 28 (including 22 and 28) of them live in cities with a population greater than 100,000 people, we sum up the probabilities for all values from 22 to 28. P(22 ≤ X ≤ 28) = Σ[P(X = k)] for k = 22 to 28. Evaluating this expression, we find that the probability is approximately 0.164.

88 people must be surveyed according to the confidence interval.

According to the statement

we have given that the mean of 152 pounds and a standard deviation of 26 pounds. And we have to find the percentage who weigh more than 180 pounds

So, For this purpose, we know that the

The given variables are which are given in the statement are:

μ = the sample mean = 152 pounds

σ = the standard deviation = 26 pounds

x = the sample value we want to test = 180 pounds

n = the sample size = unknown

MOE = margin of error = 4% = 0.04

Confidence level = 96%

Then

Firstly we find the value of the Z is :

z = (x – μ) / σ

z = (180 – 152) / 26

z = 1.0769 = 1.08

Since we are looking for the people who weigh more than 180 pounds, therefore this is a right tailed z test.

Now, The p value is:

p = 0.1401

Then we can use the formula below to solve for n:

n = z^2 * p * (1 – p) / (MOE)^2

n = 1.08^2 * 0.1401 * (1 – 0.1401) / (0.04)^2

n = 87.82 = 88

Therefore around 88 people must be surveyed.

The trigonometric ratios is concerned with the relationship of an angle of a right-angled triangle to ratios of two side lengths.

The basic trigonometric ratios includes;

sine, cosine and tangent.

recall that cos 60° = 1/2

hypotenuse = BD

cos 60° = 5 cm/BD {adjacent/hypotenuse}

1/2 = 5 cm/BD

BD = 5 cm × 2 {cross multiplication}

BD = 10 cm

The height of the triangle is BC and it is calculated as:

sin 60° = BC/BD {opposite/hypotenuse}

√3/2 = BC/10 cm {sin 60° = √3/2}

BC = 10 cm × √3/2

BC = 5√3 cm {cross multiplication}

area of the triangle = 1/2 × 5 cm × 5√3 cm

area of the triangle = 1/2 × 25√3 cm²

area of the triangle = (15√3)/2 cm²

Therefore, the length of the hypotenuse is equal to 10 cm and the area of the triangle is equal to (15√3)/2 cm² using the trigonometric ratio of for the angle 60°

To find the value of x and the length of the piece of carpet, we can set up an equation based on the given information.

The area of the rectangular piece of carpet is 60 square feet, and the width is 2 feet. The length is represented by (x^2 - 19) feet.

The formula for the area of a rectangle is length times width. Therefore, we have:

Length * Width = Area

(x^2 - 19) * 2 = 60

Now, we can solve this equation using the square root property.

Divide both sides of the equation by 2:

(x^2 - 19) = 60 / 2

x^2 - 19 = 30

Add 19 to both sides of the equation:

x^2 = 30 + 19

x^2 = 49

Take the square root of both sides:

√(x^2) = √49

x = ±7

Therefore, the value of x is ±7.

To find the length of the piece of carpet, we substitute the value of x back into the equation:

Length = x^2 - 19

Length = (±7)^2 - 19

Length = 49 - 19

Length = 30

The length of the piece of carpet is 30 feet.

So, the value of x is ±7, and the length of the piece of carpet is 30 feet.

There are nC2 different votes possible, where n is the number of bands on the list and nC2 represents the number of ways to choose 2 bands out of n.

To calculate nC2, we can use the formula for combinations, which is given by n! / (2! * (n-2)!), where ! represents factorial.

Let's say there are m bands on the list. The number of ways to choose 2 bands out of m can be calculated as m! / (2! * (m-2)!). Simplifying this expression further, we get m * (m-1) / 2.

Therefore, the number of different votes possible is m * (m-1) / 2.

In the given scenario, we don't have the specific number of bands on the list, so we cannot provide an exact number of different votes. However, you can calculate it by substituting the appropriate value of m into the formula m * (m-1) / 2.
