Answer:

Length of the rope = 15.6 ft.

Step-by-step explanation:

Given:

Height of the pole from the ground = 12 ft

Adjacent distance from the pole = 10 ft

We have to find the length of the rope attached by Scott to secure the pole.

According to the question :

In forma  right angled triangle as shown in the figure.

We have to find the measure of the hypotenuse.

Length of rope = Hypotenuse measure

Let the length of the rope = "h" ft

Using Pythagoras formula.

⇒ [tex](hypotenuse)=\sqrt{opposite^2+ adjacent^2}[/tex]

⇒ Plugging the values.

⇒ [tex]h=\sqrt{12^2 + 10^2}[/tex]

⇒ [tex]h=\sqrt{144 + 100}[/tex]

⇒ [tex]h=\sqrt{244}[/tex]

⇒ [tex]h=15.62[/tex] ft

The length of the rope, rounded to the nearest tenth is 15.6 ft.

Answer:

Hence  the probability of getting 2 spades will be 1/16

Step-by-step explanation:

Given:

Two deck if playing cards

To Find:

Probability that will get two spades

Solution:

As we know that ,there 52 playing cards in a deck

and 13 of that are spades

So probability of getting spade from a deck is ,

P(spades)=total number of spades /Total number of cards.

P=13/52

P=1/4

Similar for the second deck of card,

Required probability is that , getting spades from each deck

It is given by,

Required probability =Probability of spades in 1st AND Probability  of spade in 2nd deck

As there is use of AND operator there should multiplication of two events,

Answer: The diagonal length of the suitcase is 30 inches. Assuming that the length and height of the suitcase form a right angle (90 degree angle), you can use the Pythagorean Theorem ( a2+b2 = c2) to solve this problem. The diagonal length is equal to the square root of the sum of the length squared and the height squared.

Answer:

x^6 - (8/5)x^5 - 3x^3 + C.

Step-by-step explanation:

f(x) = 6x^5 - 8x^4 - 9x^2.

Using the general form antiderivative of Ax^m = Ax(m+1) / (m+1)+ C:

Antiderivative = 6 * x^(5+1) / 6 - 8 * x^(4+1) / 5 - 9 * x^(2+1) / 3 + C

=  6x^6/6  - 8x^5/5 - 9x^3/3 + C

= x^6 - (8/5)x^5 - 3x^3 + C.

Differentiating:

f'(x) = 6x^(6-1) - 8 x^(5-4) - 9x^(3-1) + 0

f'(x) = 6x^5 - 8x^4 - 9x^2.

The most general antiderivative of the given function f(x) = 6x5 − 8x4 − 9x2 is F(x) = x^6 - 8/5 * x^5 - 3x^3 + C, where C is the constant of the antiderivative.

To find the most general antiderivative of the given function f(x) = 6x5 − 8x4 − 9x2, we need to perform the process of integration, which is the reverse of differentiation. The antiderivative F(x) will be found by integrating each term of the function separately.
The antiderivative of f(x) will then be:  

F(x) = ∫6x5 dx - ∫8x4 dx - ∫9x2 dx,

Transitioning to the next step by applying the power rule for integration, we add 1 to the exponent and divide by the new exponent, we obtain

F(x) = 6/6 * x^(5+1) - 8/5 * x^(4+1) - 9/3 * x^(2+1) + C

Simplified, the antiderivative F(x) becomes:  

F(x) = x^6 - 8/5 * x^5 - 3x^3 + C,

where C is the constant of the antiderivative.

Answer:

14.3€

Step-by-step explanation:

Let:

[tex]C=Price\hspace{3}of\hspace{3}the\hspace{3}shirt\\P=Price\hspace{3}of\hspace{3}the\hspace{3}pants\\T=Total\hspace{3}cost[/tex]

Now, let's write the data provided by the problem, using algebraic notation.

The total cost of the clothes is 20€, so:

[tex]P+C=T\\\\P+C=20[/tex]

The price of the shirt is :

[tex]C=\frac{2}{5} P[/tex]

Replacing this value into the first equation:

[tex]P+\frac{2}{5} P=20[/tex]

Solving for P:

[tex]\frac{7}{5} P=20\\\\P=\frac{100}{7} \approx 14.3[/tex]

So, the price of the pants is 14.3€ and the price of the shirt is:

[tex]C+14.3=20\\\\C=20-14.3=5.7[/tex]

Translation:

Deja que:

[tex]C=Precio\hspace{3}de\hspace{3}la\hspace{3}camisa\\P=Precio\hspace{3}del\hspace{3}pantalon\\T=Costo\hspace{3}total[/tex]

Ahora, escribamos los datos proporcionados por el problema, usando notación algebraica.

El costo total de la ropa es de 20 €, entonces:

[tex]P+C=T\\\\P+C=20[/tex]

El precio de la camisa es:

[tex]C=\frac{2}{5} P[/tex]

Reemplazando este valor en la primera ecuación:

[tex]P+\frac{2}{5} P=20[/tex]

Resolviendo para P:

[tex]\frac{7}{5} P=20\\\\P=\frac{100}{7} \approx 14.3[/tex]

Entonces, el precio del pantalón es de 14.3 € y el precio de la camisa es:

[tex]C+14.3=20\\\\C=20-14.3=5.7[/tex]

The price of the pants is 14.3€ and the price of the shirt is: [tex]C+14.3=20\n\nC=20-14.3=5.7[/tex].

Let:

[tex]C=Price\hspace{3}of\hspace{3}the\hspace{3}shirt\nP=Price\hspace{3}of\hspace{3}the\hspace{3}pants\nT=Total\hspace{3}cost[/tex]

Now, let's write the data provided by the problem, using algebraic notation.

The total cost of the clothes is 20€, so:

P+C=T\n\nP+C=20

The price of the shirt is :

C=(2)/(5) P

Replacing this value into the first equation:

P+(2)/(5) P=20

Solving for P:

[tex](7)/(5) P=20\n\nP=(100)/(7) \approx 14.3[/tex]

So, the price of the pants is 14.3€ and the price of the shirt is:

[tex]C+14.3=20\n\nC=20-14.3=5.7[/tex].

Answer:A terminating decimal is a decimal that ends. It's a decimal with a finite number of digits

Step-by-step explanation:

Answer: A terminating decimal is a decimal that ends. It's a decimal with a fixed number of digits.

Explanation: A decimal numeral (also often just decimal or, less correctly, decimal number), refers generally to the notation of a number in the decimal numeral system. Decimals may sometimes be identified by a decimal separator (usually "." or "," as in 25.9703 or 3,1415). Decimal may also refer specifically to the digits after the decimal separator, such as in "3.14 is the approximation of π to two decimals". Zero-digits after a decimal separator serve the purpose of signifying the precision of a value.

The numbers that may be represented in the decimal system are the decimal fractions. That is, fractions of the form a/10n, where a is an integer, and n is a non-negative integer.

Answer: therefore A= 0.1 and B=0.85

Step-by-step explanation:

The values of 'a' and 'b' in the frequency table are 0.1 and 0.1

We have,

To complete the conditional relative frequency table, we need to find the values of the letters 'a' and 'b'.

We know that the total for each row and column should add up to 1.

So, we can use this information to set up two equations and solve for the values of 'a' and 'b'.

Equation 1:

0.9 + b = 0.88

This equation represents the total percentage of students aged 16 years who finish homework before 10 pm.

We subtract 0.9 and 0.88 from both sides to get:

b = 0.88 - 0.9

b = -0.02

This means that the value of 'b' is negative, which doesn't make sense.

So, we made an error in setting up the equation.

We can check the table to find the correct value of 'b'.

We know that the total for the column "Before 10 pm" should be 1.

This means that the sum of the percentages 0.9 and 'b' should be equal to 1.

So,

Equation 2:

0.9 + b = 1

Solving for 'b', we get:

b = 1 - 0.9

b = 0.1

Now, we can use Equation 2 to solve for 'a':

0.15 + a = 0.12

Subtracting 0.15 from both sides, we get:

a = 0.12 - 0.15

a = -0.03

Again, we get a negative value for 'a', which doesn't make sense.

So, we need to check our work again.

We know that the total for the row "16 years" should be 1.

This means that the sum of the percentages 0.9 and 'a' should be equal to 1.

So,

0.9 + a = 1

Solving for 'a', we get:

a = 1 - 0.9

a = 0.1

Therefore,

The values of 'a' and 'b' in the frequency table are 0.1 and 0.1

Let's solve for c.

6c−9d=111

Step 1: Add 9d to both sides.

6c−9d+9d=111+9d

6c=9d+111

Step 2: Divide both sides by 6.

6c

Second one

Let's solve for c.

5c−9d=103

Step 1: Add 9d to both sides.

5c=9d+103

Step 2: Divide both sides by 5.

5c

5

=

9d+103

5c =9/5 d+103/5

Answer:

c=8, d = -7

Step-by-step explanation:

6c - 9d = 111

5c - 9d = 103

Multiply the second equation by -1

-5c + 9d = -103

Add this to the first equation to eliminate d

6c - 9d = 111

-5c + 9d = -103

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

c        = 8

Now we need to find 9

6c - 9d = 111

Substitute in c=8

6(8) -9d = 111

48 - 9d = 111

Subtract 48 from each side

49-48 -9d = 111-48

-9d =63

Divide each side by -9

-9d/-9 = 63/-9

d = -7

Answer:

a. It is flawed because it is a voluntary response sample

Step-by-step explanation:

Sampling method:

The process of selecting the samples from the population to conduct investigation is called sampling method. The sampling method must not be biased, meaning that the samples must be selected randomly.

In the given problem, 540 ​subjects were chosen for this survey. These subjects were internet users who responded to a question that was posted on a news website. This suggests that the subjects volunteered for the survey so that means their selection was not random at all, therefore, the sampling method is flawed because it is a voluntary response sample.

Note: A voluntary response sample is a sample where subjects decide themselves whether to be a participate in the survey or not.

The sampling method is flawed because it is a voluntary response sample, potentially leading to bias as it relies on self-selected internet users. The correct option is a.

The sampling method described in the survey appears to be flawed because it is a voluntary response sample, making option (a) the correct choice.

In this survey, the participants are self-selecting internet users who chose to respond to a question on a news website. This type of sampling is known as a voluntary response sample. It is flawed because it introduces bias into the data. Those who voluntarily respond may not represent the broader population accurately. People who eat bananas regularly or have strong opinions about bananas may be more likely to respond, leading to an overrepresentation of certain groups and potentially skewing the results.

Statistical significance (option c) and being a census (option d) are not the primary issues in this case. Statistical significance depends on the sample size and how well it represents the population, and a census surveys the entire population, which is not the case here.

In summary, the sampling method used in this survey is flawed because it relies on voluntary responses and may not provide a representative view of the population's banana-eating habits.

The correct option is a. It is flawed because it is a voluntary response sample.
