Answer:

none of them are right

Step-by-step explanation:

a is 254.6153846153846.

b is 25.96078431372549

c is 2.570873786407767

d is 0.0262178217821782

if b would to be 2,648 divided by 100* it would correct but sadly none of them are correct.

Answer:

The only option that comes close is option 2.

Explanation:

Put everything into your calculator as you see it:

26,480 / 104 = 254.61

2,648 / 102 = 25.96

264.8 / 103 = 2.57

2.648 / 101 = 0.02

Answer: 12.07 ounce/gallon.

Step-by-step explanation:

given data:

desired ratio = 90grams / liter of water.

ratio In ounce/ gallon

first we convert our grams to ounce

= 98grams / 28.35

= 3.175 ounce.

converting liter to gallons

= 1/3.8

=0.263 gallons

therefore;

= 3.175 ounce / 0.263 gallons

= 12.07 ounce/gallon.

Answer:

u=(9-6w)÷-2

Step-by-step explanation:

Answer:

u = 3w - 4.5

Step-by-step explanation:

Step 1: -2u + 6w = 9 - Solve for u by isolating the variable u.

Step 2: Subtract 6w both sides

-2u = 9 - 6w

Step 3: Divide by -2 both sides

u = ( 9 - 6w ) / ( -2 )

u = 3w - 4.5

Answer:

x = 30 degrees

Step-by-step explanation:

The sum of the interior angles of a triangle is 180 degrees.

This means that 2x + 2 + 3x + x - 2 = 180.

We can then combine like terms, getting 6x = 180.

We can then divide both sides by 6, getting x = 30 degrees.

Answer:

x = 30

Step-by-step explanation:

Every triangle equals 180. So make an equation first:

2x + 2 + 3x + x - 2 = 180

Next Combine Like Terms:

6x = 180

Then Divide by 6 On Both Sides:

x = 30

Answer:

-45

Step-by-step explanation:

The question is asking for the sum of the sequence. Therefore, there is no such thing as a "radians" answer.

When you evaluate the sum, you should get -45 as your answer. To find so, you simply plug in 1 as n and other numbers then add the result.

The sum telescopes. Consider the N-th partial sum of the series,

[tex]S_N=\displaystyle\sum_{n=1}^N\bigg(\tan^{-1}\sqrt n-\tan^{-1}\sqrt{n+1}\bigg)[/tex]

[tex]S_N=\bigg(\tan^{-1}\sqrt1-\tan^{-1}\sqrt2\bigg)+\bigg(\tan^{-1}\sqrt2-\tan^{-1}\sqrt3\bigg)+\bigg(\tan^{-1}\sqrt3-\tan^{-1}\sqrt4\bigg)+\cdots+\bigg(\tan^{-1}\sqrt N-\tan^{-1}\sqrt{N+1}\bigg)[/tex]

Notice how [tex]\tan^{-1}\sqrt2[/tex] is added, then immediately subtracted. The same goes for [tex]\tan^{-1}\sqrt3[/tex], then [tex]\tan^{-1}\sqrt4[/tex], and so on, up to [tex]\tan^{-1}\sqrt N[/tex]. This leaves us with

[tex]S_N=\tan^{-1}\sqrt1-\tan^{-1}\sqrt{N+1}[/tex]

The value of the given sum is obtained as [tex]N\to\infty[/tex]. We get

[tex]\displaystyle\sum_{n=1}^\infty\bigg(\tan^{-1}\sqrt n-\tan^{-1}\sqrt{n+1}\bigg)=\lim_{N\to\infty}S_N=\tan^{-1}1-\lim_{N\to\infty}\tan^{-1}\sqrt{N+1}[/tex]

To compute the limit, recall that [tex]\tan^{-1}x[/tex] has a range of [tex]\left(-\frac\pi2,\frac\pi2\right)[/tex]; in particular, [tex]\tan^{-1}x\to\frac\pi2[/tex] as [tex]x\to\infty[/tex]. So we have

[tex]\displaystyle\sum_{n=1}^\infty\bigg(\tan^{-1}\sqrt n-\tan^{-1}\sqrt{n+1}\bigg)=\frac\pi4-\frac\pi2=\boxed{-\frac\pi4}[/tex]

Step-by-step explanation:

The domain of a graph is all of the possible x values, and the range is all possible y values.

7. The graph goes on for both the x and y values, so the domain is (-inf, inf) and the range is (-inf, inf).

8. In this case, the domain is also (-inf, inf), but the range is [-2, inf) as there are no y values less than -2.

9. The domain is [-2, 2], as the x values only range from -2 to 2. The range is [-3, 3] as the y values range from -3 to 3.

10. The domain is (-inf, inf) because all x values are possible. The range is [-1, 1], as there are no y values greater than 1 or less than -1.

The distance of diameter = [tex]\sqrt{85}[/tex]

The common ratio of the geometric sequence is -1/3

What is Geometric Progression?

A geometric progression is a sequence in which each term is derived by multiplying or dividing the preceding term by a fixed number called the common ratio.

The nth term of a GP is aₙ = arⁿ⁻¹

The general form of a GP is a, ar, ar2, ar3 and so on

Sum of first n terms of a GP is Sₙ = a(rⁿ-1) / ( r - 1 )

Given data ,

Let the geometric sequence be represented by A

Now , the value of A is

A = 18 , -6 , 2 , -2/3

Let the first term of the geometric sequence be = a₁

The value of a₁ = 18

Let the second term of the geometric sequence be = a₂

The value of a₂ = -6

And , the common ratio r is given by the formula

Common ratio r = second term / first term

Substituting the values in the equation , we get

Common ratio r = -6/18

On simplifying the equation , we get

Common ratio r = -1/3

Therefore , the ratio is -1/3

Hence , The common ratio of the geometric sequence is -1/3

Add 15 to each side using the addition property of equality

7y -15+15 = -29+15

7y = -14

Divide each side by 7 using the inverse property of multiplication

The complete question is:

Mr. Molesky observes a group of monkeys for 24 hours to learn about their behavior. He records how long they slept (in hours), how many bananas they ate, gender, age (in years), and the specific breed of monkey.

(a) What are the individuals in this data set?

(b) Identify the variables that were recorded, and indicate whether each one is categorical or quantitative?

Solution:

(a)

The term "individuals", in statistics, implies or denotes the objects or people included in a statistical study.

In this case it is provided that Mr. Molesky observes a group of monkeys for 24 hours to learn about their behavior.

So, the "individuals" in this data set are the monkeys.

(b)

Categorical variables belong to a certain category or label values. Such as gender of a person, state from which a person is from, color of the marble and so on.

Quantitative variables are those variables that assume numerical values and represent some sort of measurement. Such as height, weight, annual income of the people working at the same place and so on.

In this case the variables are:

Number of bananas the monkeys ate - Quantitative variable

Gender - Categorical variable

Age (in years) -  Quantitative variable

Specific breed of monkey - Categorical variable

The individuals in the data set refers to each monkey used in the experiment.

The variables in the experiment include :

Individuals used in a research refers to each species or subject used in the research finding.

DISCRETE variables involves variables whose values or numbers can be obtained by counting.while

CONTINUOUS variables include variable measure are obtained by measurement such as height and weight.
