Assign the variable "x" to represent the unknown number.

The equation based on the statement is:
_____________________________________
(⅔)x + 4 = 7.
_____________________________________
To solve for "x":

First, subtract "4" from both sides:

(⅔)x + 4 − 4 = 7 − 4;

which simplifies to:

(⅔)x = 3;

Next, multiply both sides by "3" to eliminate the fraction's denominator:

3 × (⅔)x = 3 × 3;

resulting in: 2x = 9;

Finally, divide both sides by "2" to isolate "x":
__________________________________________________
(2x) / 2 = 9 / 2

x = 9/2 = "4 ½" or "4.5".

Let's denote the unknown number as 'n'.
The plus sign represents addition.
The word 'is' corresponds to the equals sign.

So, the expression can be written as: $\frac{2}{3}$ n + 4 = 7

Thus, there are five distinct flavors. A group of 180 individuals was surveyed. Accordingly, the null hypothesis suggests no significant difference, with each flavor receiving 180/5 = 36 counts. x^2 = $\sum{\frac{(x_i)^2}{m_i}}-n$ . Here, mi indicates the expected frequency based on the hypothesis, which is 36, n = 180, and xi corresponds to the actual observations. By substituting the known values, we find that x^2 = 9. The level of association is expressed as $\sqrt{X^2}/ \sqrt{N(n-1)}$ . This results in approximately 0.10, which surpasses our threshold.

Answer:

F(t) = 10 + 5(t)

Step-by-step explanation:

The complete question is as follows;

Anumeha is mowing lawns for a summer job. For each lawn she mows, she charges a $10 starting fee plus an hourly rate. For example, her fee for a 5-hour job is $35. Let f(t) denote Anumeha's fee for a job f (in dollars) based on how many hours (t) were needed to finish it. Write the formula for this function.

Solution

We aim to establish the formula F(t) representing the fee Anumeha charges per job.

Key to formulating this function is understanding the constant charge she applies per job.

We know she earns $35 for mowing for 5 hours.

Therefore, the constant fee can be deduced as follows;

Since it’s a $10 starting fee along with an hourly rate;

35 = 10 + 5(x)

where x refers to the hourly rate

35 = 10 + 5x

5x = 35-10

5x = 25

x = 25/5

x = $5

This indicates that she charges a constant fee of $5 per hour

Thus, we can now write the equation.

F(t) = 10 + 5(t)

where t represents the number of hours spent on each job

Which distribution exhibits a negative skew?

zzz [12365]

<span>Skewness serves as a descriptive statistic in the analysis of data distribution. In the realm of finance and investing, skewness is considered alongside other statistics such as kurtosis and value at risk (VAR). When assessing investment returns, skewness reflects the asymmetry present in these returns. Normally distributed data sets will have a skewness of zero, whereas investment returns frequently deviate from a normal distribution.

In graphs showcasing investment returns displaying positive skewness, this indicates that: mean > median > mode. Conversely, a negative skewness reveals the relationship: mean < median < mode.

Evaluating skewness is crucial in reviewing investment returns, as it signals potential risks based on historical return patterns. Despite a negative skew indicating a high occurrence of smaller gains, it can also alert to the chance, albeit remote, of an extremely adverse outcome.</span>
