The two opposite numbers are given as follows:

-4.5 and 4.5.

The opposite of a number is obtained exchanging just the signal of the number.

The opposite of a number x is then given as follows:

-x.

The two numbers in this problem are nine units away, hence the value of x is obtained as follows:

x - (-x) = 9.

2x = 9

x = 9/2

x = 4.5.

Hence the numbers are:

-x = -4.5 and x = 4.5.

An equation is an expression that contains numbers and variables linked together by mathematical operations of addition, subtraction, multiplication, division and exponents. An equation can either  be linear, quadratic, cubic, depending of the degree of the variable.

Two opposite numbers are 9 units away from each other.

Let x represent the number. Hence, x and -x are 9 units away. Therefore:

x - (-x) = 9

x + x = 9

2x = 9

x = 4.5

The two opposite numbers are 4.5 and -4.5.

Step-by-step explanation:

Answer:

6 times

Step-by-step explanation:

If there are total of 6 marbles and 3 are pink, then you will have a one half (or 50%) chance of picking a pink marble. Because you put the marble back each time, your chance of picking a pink marble remains the same every time.

So one half of 12 is 6. You are predicted to pick a pink marble 6/12 times.

Degree of freedom for chi-square test for 10 categories will be 9.

What is chi- square test?

A test that evaluates how well a model matches real observed data is that the chi-square (χ²) statistic. A chi-square statistic can only be calculated with data that's random, unprocessed, mutually exclusive, obtained from independent variables, and drawn from a large enough sample.

The Formula for Chi-Square Is

χ(c)=²∑(Oₐ-Eₐ)₂/Eₐ²

where:

c=Degrees of freedom

O=Observed value(s)

E=Expected value(s)

​

Main Body:

Degree of freedom = total categories -1

so no. of categories= 10

Degree of freedom = 10 - 1

Answer:

The bike path

Step-by-step explanation:

A right triangle has a hypotenuse that can be found using the formula

a^2 + b^2 = c^2 where c is the hypotenuse

The street sign is obviously not correct because a hypotenuse is longer than the sides. The bathroom tile isn't correct either because 6^2 + 8^2 = 100, or 10 after you take the square root. That leaves the bike path.

Checking to make sure:

5^2 + 12^2 = c^2

25 + 144 = √169

√169 = 13

The scenario from the given scenarios involving a right triangle is: "A triangular bike path with lengths of 5 miles, 12 miles, and 13 miles", as the sides satisfy the Pythagoras theorem.

Any three line segments can form a right triangle only when they satisfy the Pythagoras Theorem, according to which, the square of the largest side in a right triangle is equal to the sum of the squares of the other two sides, that is, a² = b² + c², where a is the largest side, and b and c are the two other sides.

In the question, we are asked to identify from the given scenarios, the case that involves a right triangle.

We know that for three segments to be a right triangle, they need to satisfy the Pythagoras Theorem. So we check every scenario with the theorem:

The silk density in g/cc if the specific gravity of the fiber is given as 1.32 is given as 1.32 g/cc.

Density is the mass of a material substance per unit volume. d = M/V, where d is density, M is mass, and V is volume, is the formula for density. Grams per cubic centimetre are a typical unit of measurement for density.

For instance, whereas Earth has a density of 5.51 grammes per cubic centimetre, water has a density of 1 grammes per cubic centimetre. Another way to state density is in kilogrammes per cubic metre (in metre-kilogram-second or SI units). For instance, air weighs 1.2 pounds per cubic metre. In textbooks and manuals, the densities of typical solids, liquids, and gases are stated.

As we know that ,

Specific gravity = Density of object / density of water

1.32 = silk density / 1 g/cc

[Density of water is 1 g/cc]

Silk density = 1.32 x 1 g/cc

Silk density = 1.32 g/cc.

The equation log₂(x - 1) = x³ - 4x has one solution at x = 2.

To determine the solutions to the equation log₂(x - 1) = x³ - 4x, we can set the two expressions equal to each other:

log₂(x - 1) = x³ - 4x

Since we know that the graphs of the two functions intersect at the points (2, 0) and (1.1187, -3.075), we can substitute these values into the equation to find the solutions.

For the point (2, 0):

log₂(2 - 1) = 2³ - 4(2)

log₂(1) = 8 - 8

0 = 0

The equation holds true for the point (2, 0), so (2, 0) is one solution.

For the point (1.1187, -3.075):

log₂(1.1187 - 1) = (1.1187)³ - 4(1.1187)

log₂(0.1187) = 1.4013 - 4.4748

-3.075 = -3.0735 (approx.)

The equation is not satisfied for the point (1.1187, -3.075), so (1.1187, -3.075) is not a solution.

Therefore, the equation log₂(x - 1) = x³ - 4x has one solution at x = 2.

Step-by-step explanation:

Since it is a right angled triangle, we'll use the Pythagoras theorem to check If the lenghts are equal.

From the three lenghts given the longer side should be the hypotenus, that is 9, while the other two are the shorter sides. Therefore :

c² = a² + b²

9² = 6² + 8²

81 ≠ 100

Hence it is not a right angle triangle.

The number of ways are there of choosing ten balls from the box if the number of green balls must be in even numbers =15946 ways

To determine the number of ways of choosing ten balls from the box such that the number of green balls chosen is even, we need to consider the different possible combinations of green balls that could be chosen.

First, we can select 0 green balls, in which case we would need to choose all 10 balls from the 5 red and 8 yellow balls. This can be done in (5+8) choose 10 ways, which is 13 choose 10, or 286 ways.

Alternatively, we could choose 2, 4, or 6 green balls, and then select the remaining balls from the red and yellow balls. To count the number of ways of doing this, we can use the binomial coefficient formula.

The total number of ways of selecting 10 balls from the box is (6+5+8) choose 10, which is 19 choose 10, or 92,378 ways.

Therefore, the number of ways of choosing 10 balls from the box such that the number of green balls chosen is even is the sum of the number of ways of choosing 0, 2, 4, or 6 green balls, which is:

(6 choose 0)(13 choose 10) + (6 choose 2)(5 choose 8)(8 choose 0) + (6 choose 4)(5 choose 6)(8 choose 0) + (6 choose 6)(5 choose 4)*(8 choose 0)

Simplifying this expression gives a total of 15,946 ways.

If the difference between the water temperature and the room temperature is halved every 5 minutes, then the water temperature in degrees fahrenheit, after 15 minutes 86 f        

If a cup is boiling water (212 f) is placed to cool in a room whose temperature remains constant at 68 f. suppose the difference between the water temperature and the room temperature is halved every 5 minutes .

Temperature can be measured in degree celsius, degree fahrenheit and kelvin. so here the temperature measured in degree fahrenheit

Initially the difference between water and room temperature is,

212 - 68 = 144f                

For every 5 minutes the difference of water and room temperature is halved,

After 5 minutes the difference is, 144/2 = 72 f

After 10 minutes the difference is, 72/2 = 36 f

After 15 minutes the difference is, 36/2 = 18 f

So the water temperature in degrees fahrenheit, after 15 minutes will be the sum of room temperature and difference between the temperatures of water and room after 15 minutes and it is given as, 18 f + 68 f = 86 f

Therefore, the water temperature in degrees fahrenheit, after 15 minutes is 86 f.

The t-score of 2.779 is used to find the 99% confidence interval for the population mean.

Given,

Assume that orangutans' heights, measured in inches, are regularly distributed with an unidentified mean and standard deviation. The population means are calculated using the orangutan heights of 27 orangutans that were randomly selected.

What t-score should be applied to determine the population mean's 99% confidence interval?

n = 27

confidence level = 0.99

We have to find a critical value for the confidence level of 0.99.

To find the critical value we need degrees of freedom and significance level.

df = n-1 = 27 - 1 = 26

α = 1 - 0.99 = 0.01

α/2 = 0.01/2 = 0.005

Step-by-step explanation:

The number of seats in each row of the hall is 40

Given that there are 3200 seats overall and that there are twice as many rows as there are seats in each row.

The total capacity of the hall=3200

Number of rows= 2 ( number of seats in each row)

Let's assume the number of seats in each row=x

⇒Number of rows=2x

The total capacity of the hall = (number of rows)( number of seats in each row)

The total capacity of the hall=3200

3200 = (2x) × (x)

[number of rows=2x, number of seats in each row=x]

3200 = 2\(x^{2}\)
