Young adults might value credit in case of an emergency for several reasons. Firstly, credit provides financial flexibility, allowing them to access funds quickly when unexpected expenses arise.

This can be essential for covering costs related to medical emergencies, car repairs, or other unforeseen events that may strain their limited savings. Secondly, young adults often have less established financial safety nets than older individuals. They may not have significant savings, insurance policies, or support from family members to fall back on during emergencies. Credit, in this case, acts as a temporary financial cushion, enabling them to manage immediate needs without resorting to high-interest loans or further jeopardizing their financial stability.

Thirdly, responsible use of credit can help young adults build a positive credit history. Demonstrating responsible borrowing and repayment habits will make it easier for them to access more favorable credit terms in the future, such as lower interest rates or higher credit limits. This can prove valuable when making significant purchases, like buying a home or financing higher education.

Lastly, having access to credit can also provide young adults with a sense of financial independence and empowerment. Knowing they have the means to handle emergencies without relying on others can boost their confidence in managing personal finances and help them make more informed financial decisions as they navigate adulthood.

a.The Industry Average Salary is $55,680. b.The Firm A's Average Salary is $51,718.40 .c. Firm B's average salary is approximately 112.27% of Firm A's average salary.

a. To determine the industry average salary, we can use the information that the industry average salary is 96% of Firm B's average salary. Firm B's average salary is $58,000. Therefore, we can calculate the industry average salary as follows:

Industry Average Salary = 96% of Firm B's Average Salary

= 0.96 * $58,000

= $55,680

b. Firm A's average salary is stated as 93% of the industry average salary. To calculate Firm A's average salary, we can multiply the industry average salary by 93%:

Firm A's Average Salary = 93% of Industry Average Salary

= 0.93 * $55,680

= $51,718.40

c. To express Firm B's average salary as a percentage of Firm A's average salary, we can divide Firm B's average salary by Firm A's average salary and multiply by 100:

Percentage = (Firm B's Average Salary / Firm A's Average Salary) * 100

= ($58,000 / $51,718.40) * 100

≈ 112.27%

Answer:

  28 mph

Step-by-step explanation:

Given that a car moving 36 mph takes 7 hours for a trip, you want to know the speed if the trip takes 9 hours.

The speed and time vary inversely for the same distance. If the time goes up by a factor of 9/7, the speed will go down by the inverse factor: 7/9.

  7/9 × 36 mph = 28 mph

The speed of the car is 28 mph for the 9-hour trip.

Answer:

994

Step-by-step explanation:

We have the expression:

\((8+t)^3-6\)

And we want to evaluate it when t=2.

Hence, we will substitute 2 for t and evaluate. Therefore:

\(=(8+2)^3-6 \\\\ =(10)^3-6\\ \\ =1000-6\\\\=994\)

Therefore, our final answer is 994.

The vertex of the graphed function f(x) = [x - 4] + 3 is (4, 3).

The function f(x) = [x - 4] + 3 is in the form of an absolute value function, where the expression inside the absolute value brackets represents the input value shifted horizontally by 4 units to the right.

The constant term of 3 represents a vertical shift upwards by 3 units.

To find the vertex of this function, we need to determine the x-coordinate that corresponds to the minimum value of the absolute value function.

In this case, since the absolute value function is within brackets and not being multiplied or divided by a coefficient, the minimum value occurs at the point where the expression inside the brackets equals zero.

Therefore, setting x - 4 = 0, we find x = 4.

Substituting this x-value into the function, we find f(4) = [4 - 4] + 3 = 3. So the vertex of the graphed function is located at the point (4, 3), where x = 4 and y = 3. This means that the graph is shifted 4 units to the right and 3 units upward from the origin.

20 days

Change of the number of skateboards with respect to the change of days.

y intercept represents the total stock of the skateboard wheels.

Step-by-step explanation:

The points on the plane are \((3,272)\) and \((7,208)\).

Slope is given by

\(m=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{208-272}{7-3}\\\Rightarrow m=-16\)

The equation of the line will be

\(y-y_1=m(x-x_1)\\\Rightarrow y-272=-16(x-3)\\\Rightarrow y-272=-16x+48\\\Rightarrow y=-16x+320\)

The equation that represents the situation is \(y=-16x+320\)

When the number of days is 11 we have \(x=11\)

\(y=-16\times 11+320\\\Rightarrow y=144\)

The number of wheels left after 11 day is 144.

When the shipment will run out \(y=0\)

\(0=-16x+320\\\Rightarrow x=\dfrac{320}{16}\\\Rightarrow x=20\)

So, after 20 days the shipment will run out.

The slope represents the change of the number of skateboards with respect to the change of days.

The y intercept represents the total stock of the skateboard wheels.

Inner diameter of the tube = 5.8cm, radius = 2.9cm

length = 1120cm

Thickness everywhere = 2mm = 0.2cm

Unknown:

Volume of the metal = ?

Solution:

To solve this, use the expression below;

   Volume  = \(\pi( R^{2} - r^{2} ) h\)

We calculate sample mean and std deviation from given data.

Sample Mean, \($ {\overset{-}X} =\frac{\Sigma (X)}{n} $\)   =269.8/10=26.98

Sample Variance, \($s^2= \frac{\Sigma(X-{\overset{-}X})^2}{(n-1)}$\)    =1859.496/9=206.610667

Sample std dev,s=\($\sqrt{s^2}$\)=√206.610667≈14.373958

We want to test two tailed hypothesis:

\($H_0$\) : σ=12

\($H_2$\) : σ≠12

Given: s=14.373958⇒ \($s^2$\) =206.610667,n=10

Significance level, a=0.1 Degrees of freedom, df=n-1=9

Since this is two tailed test, we need area of α=0.1 on either side of critical value. This means area of 0.05 on right of positive critical value.

Critical values are given by \($ X_{1-\alpha/2}^2 =X_{0.95}^2 \text{ and}\ X_{1-\alpha/2}^2 =X_{0.95}^2 $\)  with 9 degrees of freedom.

We can use chi-square table or following excel commands:

CHISQ. INV(0.95,9)=3.32511284307

CHISQ. INV (0.05,9)=16.9189776046

Critical Values, \($X_L^2$\)=3.325  and \($X_R^2$\)=16.919

Since this is two tailed test, the decision rule or rejection criteria is:

Reject null hypothesis if test statistic is less than or equal to left critical value OR more than or equal to right critical value, i.e,

Reject \($H_0$\)   if \($x^2$\)≤3.325  OR \($x^2$\)≥16.919

Test statistic is given by \($X^2=\frac{(n-1)s^2}{\sigma^2}$\) =((9)*206.610667)/144=12.913167    

Test statistic, \($x^2$\)=12.913

since test statistic is between two critical values, we (do not reject \($H_0$\)) (i.e, we fail to reject \($H_0$\).

Conclusion: There is (not sufficient) evidence to conclude that standard deviation is not equal to 12 .

Alternatively, we can use p-value approach. The decision rule or rejection criteria is: reject null hypothesis if p-value is less than or equal to significance level (α), i.e, reject \($H_0$\) if p-value ≤0.1

P-value is twice the (smaller) tail area of test statistic because this is two tailed test. We can use excel function to find this. 2*M IN (CHISQ.DIST (12.913167,9,  TRUE ) 1-CHISQ.DIST 12.913167,9,  TRUE ) =0.333149809868

P-value =0.3331

since p-value is greater than significance level (α),we (do not reject \($H_0$\)) (i.e, we fail to reject \($H_0$\)).

Conclusion: There is (not sufficient) evidence to conclude that standard deviation is different from 12 .

The total number of possible outcomes is given by the expression 6n × 52, where n represents the number of marbles to choose from.

To determine the number of possible outcomes, we need to consider the number of outcomes for each event and then multiply them together.

1. Picking a marble: Let's assume there are n marbles to choose from. If there are n marbles, then the number of outcomes for this event is n.

2. Rolling a die: A standard die has 6 sides numbered 1 to 6. Therefore, the number of outcomes for this event is 6.

3. Picking a card: A standard deck of cards has 52 cards. Hence, the number of outcomes for this event is 52.

To find the total number of possible outcomes, we multiply the number of outcomes for each event together:

Total number of outcomes = (number of outcomes for picking a marble) × (number of outcomes for rolling a die) × (number of outcomes for picking a card)

Total number of outcomes = n × 6 × 52

Therefore, the total number of possible outcomes is given by the expression 6n × 52, where n represents the number of marbles to choose from.
