What decimal number is illustrated?

To represent the sum of 3/4 + (-1.75), we can start at 3/4 and move left by 1 and 3/4 units (since -1.75 is equivalent to subtracting 1 whole unit and 3/4). Option (C) represents this on the number line model.

To find the sum of 3/4 and -1.75, we need to add the two numbers. One way to do this is to rewrite -1.75 as a fraction with a common denominator of 4.

-1.75 = -1 - 0.75 = -4/4 - 3/4 = -7/4

Now we can add the two fractions:

3/4 + (-1.75) = 3/4 - 7/4 = -4/4 = -1

So the sum of 3/4 and -1.75 is -1.

The number line model that represents this sum is the fourth option, which shows 3/4 and -1.75 on the number line and their sum, -1, marked on the line.

Answer:

l = 194999.45

Step-by-step explanation:

I'm going to assume that you meant 3.14 by 3,14.

336,765 = 3.14 × 0.55 × (l + 0.55)

336,765 ÷ (3.14 × 0.55) = l + 0.55

(336,765 ÷ (3.14 × 0.55)) - 0.55 = l

l = 194999.45

A linear system has infinite solutions if it consists of exactly the same equations.

The 3  possible solutions of a linear system are:

- Unique or one solution

- Infinite solutions

- No solution

- If the linear equations are exactly (or can be transformed to exactly) the same equations, the solution is infinite.

Example:

3x + 2y = -4  ..... (equation 1)

6x = -4y - 8   ..... (equation 2)

Add 4y to both sides of equation 2:

6x + 4y = -8

Divide both sides by 3:

3x + 2y = -4

Hence, equation 2 is exactly the same as equation 1. If we plot their graphs, they will share the same graph. Any solution of equation 1 is also solution of equation 2. Therefore, this linear system has infinite solutions.

Step-by-step explanation:

The ratio of the number of tulips to the number of roses in Julia's garden is 5:4.Let's represent the number of roses as 'r' and the number of tulips as 't'.

According to the given information, one half of the number of roses is equal to two fifths of the number of tulips. Mathematically, this can be expressed as:

(1/2) * r = (2/5) * t

To find the ratio of the number of tulips to the number of roses, we divide both sides of the equation by 'r':

(1/2) = (2/5) * t / r

Now, we can simplify the equation:

(1/2) = (2/5) * (t/r)

To eliminate the fraction, we can multiply both sides of the equation by 2:

2 * (1/2) = 2 * (2/5) * (t/r)

1 = (4/5) * (t/r)

Finally, to isolate the ratio of tulips to roses, we divide both sides of the equation by (4/5):

1 / (4/5) = (4/5) * (t/r) / (4/5)

5/4 = (t/r)

Therefore, the ratio of the number of tulips to the number of roses in Julia's garden is 5:4.

Answer:

The mean of C is 170 households

The standard deviation of C, is approximately 5 households

Step-by-step explanation:

The given parameters are;

The percentage of households in the United States that had a computer in 2014 = 85%

The size of the randomly selected sample in 2014, n = 200

The random variable representing the number of households that had a computer = C

Therefore, we have;

The probability of a household having a computer P = 85/100 = 0.85

Let

Therefore;

The mean (expected) number in the sample, μₓ, = E(x) = n × P is given as follows;

μₓ = 200 × 0.85 = 170

The mean of C = μₓ = 170

The variance, σ² = n × P × (1 - P) = 200 × 0.85 × (1 - 0.85) = 25.5

Therefore;

The standard deviation, σ = √(σ²) = √(25.5) ≈ 5.05

The standard deviation of C, σ ≈ 5 households (we round (down) to the nearest whole number)

The mean and the standard deviation of C are 170 and 5.05 respectively

The given parameters are:

\(\mathbf{n = 200}\) -- the sample size

\(\mathbf{p = 85\%}\) -- the proportion of household that had a computer

(a) The mean

This is calculated as:

\(\mathbf{\bar x = np}\)

So, we have:

\(\mathbf{\bar x = 200 \times 85\%}\)

\(\mathbf{\bar x = 170}\)

(b) The standard deviation

This is calculated as:

\(\mathbf{\sigma = \sqrt{np(1 - p)}}\)

So, we have:

\(\mathbf{\sigma = \sqrt{170 \times (1 - 85\%)}}\)

\(\mathbf{\sigma = \sqrt{170 \times 15\%}}\)

\(\mathbf{\sigma = \sqrt{25.5}}\)

Take square roots

\(\mathbf{\sigma = 5.05}\)

Hence, the mean and the standard deviation of C are 170 and 5.05 respectively

The given function is `y = sin(3θ)/(5θ)`. We need to find the intervals on which the function is continuous. Let's begin. Let's write the given function as a product of two functions which are continuous for all values of θ.Explanation:Given function is `y = sin(3θ)/(5θ)`

.For continuity of the given function, we need to check if it can be written as a product of two functions, which are continuous for all values of θ.

As the given function has two functions `sin(3θ)` and `1/(5θ)`,

Let us check the continuity of both functions at θ = 0.1. `sin(3θ)` is continuous for all values of θ.2. `1/(5θ)` is discontinuous at θ = 0.

So, the given function can not be written as a product of two functions that are continuous for all values of θ.

Hence, the given function `y = sin(3θ)/(5θ)` is discontinuous only

when θ = 0.

Therefore, option A. discontinuous only when theta = 0 is the correct answer.

A sequence is a list of numbers or other objects in mathematics that is arranged according to a pattern or rule. Every component of the sequence is referred to as a term, and each term's place in the sequence is indicated by its index or position number. Sequences may have an end or an infinity. While infinite sequences never end, finite sequences have a set number of terms. Sequences can be created directly by generating each term using a formula or rule, or recursively by making each term dependent on earlier terms. Numerous areas of mathematics, including calculus, number theory, and discrete mathematics, all study sequences.

Instead, the sequence oscillates between two values.Therefore, the sequence {(-1)"} diverges in R.(b) {1- (-1)"}Here, the terms of the sequence alternate between 0 and 2.

Explanation:

H = heads

T = tails

HHH means we get 3 heads in a row, HHT means heads twice then tails the third time, and so on.

Here are the 8 ways to flip three coins (note: 2^3 = 2*2*2 = 8).

We see that HHH only comes up once out of 8 total times. Therefore, the probability of getting HHH is 1/8

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

Another way to see the answer is note that P(H) = 1/2 is the probability of getting heads on a single coin flip

Then with two coin flips, we have P(HH) = P(H)*P(H) = (1/2)*(1/2) = 1/4. Each coin flip is independent of one another.

And finally, P(HHH) = P(H)*P(H)*P(H) = (1/2)*(1/2)*(1/2) = 1/8

The fraction which represents the total kg of cherries that Noah and Mai have is (D) (1 + 1/2) * 3 kg.

An element of a whole is a fraction.

The number is represented mathematically as a quotient, where the numerator and denominator are split.

Both are integers in a simple fraction.

A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.

So, we know that:

Noah = 3 kg

Mai = 3/2 kg

Which can be represented as:

(1 + 1/2) * 3

Therefore, the fraction which represents the total kg of cherries that Noah and Mai have is (D) (1 + 1/2) * 3 kg.

In summary, regardless of the values of μ and σ, you can calculate z-scores by subtracting the mean from the value of interest and then dividing by the standard deviation.

To find z-scores for normal distributions where μ (mean) is not equal to 0 or σ (standard deviation) is not equal to 1, you need to use the formula for standardizing a value using the z-score formula:

z = (x - μ) / σ

Here, x is the value you want to standardize, μ is the mean of the distribution, and σ is the standard deviation.

To find the z-score for a specific value, you subtract the mean from that value and then divide the result by the standard deviation. This calculation allows you to determine how many standard deviations away from the mean the value is.

For example, if you have a normal distribution with a mean of 10 and a standard deviation of 2, and you want to find the z-score for a value of 14, you would use the formula:

z = (14 - 10) / 2

z = 4 / 2

z = 2

The z-score of 2 indicates that the value of 14 is two standard deviations above the mean.

The number one advantage of an experiment over an observational study is that an experiment allows for the manipulation of variables and the establishment of cause-and-effect relationships between variables.

In an experiment, researchers can control and manipulate the independent variable (the variable being tested) and observe the effects on the dependent variable (the variable being measured).

This level of control allows researchers to establish causal relationships between variables, which cannot be done in observational studies, where the researcher merely observes and measures the variables without intervening or manipulating them.

In other words, experiments allow researchers to determine whether a change in the independent variable causes a change in the dependent variable, which is crucial for making informed decisions in fields such as medicine, psychology, and social sciences.
