Step-by-step explanation:

The formula for finding a magnitude of an earthquake on the Richter Scale is given as
[tex]R = \log\left(\dfrac{A}{A_0}\right)\\[/tex]

[tex]\rm{where}\\\textrm{A - measure of amplitude of quake wave}\\\textrm{$A_0$ = amplitude of smallest detectable wave}\\[/tex]

Given A = 0.3954 and A₀ = 0.0001, we can plug in these values into the R equation to get

Answer:

First, let's calculate the total cost of buying the shares:

1000 shares * $15.23/share = $15,230

Next, we need to calculate the commission paid to the broker for buying the shares:

$15,230 * 0.0075 = $114.23

So, the total cost of buying the shares including the commission is:

$15,230 + $114.23 = $15,344.23

Now, let's calculate the total revenue from selling the shares:

1000 shares * $18.78/share = $18,780

We also need to calculate the commission paid to the broker for selling the shares:

$18,780 * 0.0075 = $140.85

So, the total revenue from selling the shares after the commission is:

$18,780 - $140.85 = $18,639.15

The total profit from buying and selling the shares is:

$18,639.15 - $15,344.23 = $3,294.92

The rate of return is the profit divided by the total cost, expressed as a percentage:

($3,294.92 / $15,344.23) * 100% = 21.5%

Therefore, Omar's rate of return is 21.5%.

The relation shown in the graph is not a function because it violates the vertical line test.

We have,

The relation shown in the graph is not a function because it violates the vertical line test.

The vertical line test states that for a relationship to be a function, every vertical line drawn on the graph should intersect the graph at most once.

However, in this case, the U-shaped graph intersects the vertical line at multiple points, such as (-2, -2) and (2, 2).

Therefore, the relation does not meet the criteria of a function.

The Eric's time can be represented by the equation t = (d/60) - 2.

To create a second equation showing how long it would take Eric to travel the same distance as Noah, we can use the formula distance = speed x time. Let's call the distance that both Noah and Eric travel "d" (since we don't know the actual distance).

We know that Noah's speed is 135 mph and Eric's speed is 60 mph. We also know that Eric takes two hours longer to travel the same distance as Noah.

So, if we let "t" be the time it takes Noah to travel "d" distance, then Eric's time can be represented as "t + 2" hours. Putting all of this together, we can create the following equation: d = 135t (for Noah) and d = 60(t + 2) (for Eric).

From this second equation, we can solve for Eric's time by dividing both sides by 60, which gives us t + 2 = d/60.

The amount of money Gillians owes for student loans is $12,250

How to determine this

When Gillians net worth = $90,500

Checking account = $950

Credit- card = -$2,650

Automobile(current value) = $10,300

The cost of the burger is $10.50, the cost of the souvenir is $28.00, and the cost of the pass is $42.00.

Let's assume the cost of the pass is x dollars.

According to the given information:

The burger costs 1/4 of the souvenir, so the burger's cost is[tex](1/4) \times x[/tex]dollars.

The souvenir costs 2/3 of the pass, so the souvenir's cost is [tex](2/3) \times x[/tex]dollars.

Mark had $4.50 left over after buying these items, so we can set up the following equation:

[tex]43.00 - [(1/4) \times x + (2/3) \times x] = $4.50[/tex]

Simplifying the equation, we have:

[tex]43.00 - [(1/4) \times x + (2/3) \times x] = $4.50[/tex]

[tex]43.00 - (1/4 + 2/3) \times x = $4.50[/tex]

[tex]43.00 - (3/12 + 8/12) \times x = $4.50[/tex]

[tex]43.00 - (11/12) \times x = $4.50[/tex]

To solve for x, we'll isolate the variable on one side of the equation:

$43.00 - $4.50 = (11/12) * x

$38.50 = (11/12) * x

Now, we can solve for x by multiplying both sides of the equation by (12/11):

[tex](12/11) \times $38.50 = x[/tex]

$42.00 = x

Therefore, the cost of the pass is $42.00.

Now we can find the costs of the burger and the souvenir:

The burger costs 1/4 of the souvenir, so its cost is (1/4) * $42.00 = $10.50.

The souvenir costs 2/3 of the pass, so its cost is (2/3) * $42.00 = $28.00.

The area of the entire figure can be found by adding the areas of the four triangles:

Area of entire figure

= Area of triangle ABC + Area of triangle ACD + Area of triangle ABD + Area of triangle BCD

= (1/2)(5)(3) + (1/2)(3)(4) + (1/2)(4)(3) + (1/2)(3)(4)

= 7.5 + 6 + 6 + 6

Similarly, the area of region A can be found by adding the areas of triangles ABC and ABD:

Area of region A

= Area of triangle ABC + Area of triangle ABD

= (1/2)(5)(3) + (1/2)(4)(3)

= 7.5 + 6

Therefore, the probability of the point being in region A is:

P(A) = Area of region A / Area of entire figure

The inequality 2|x - 3| + 6 > 10 has the solution set:

x < 1 or x > 5

To solve the inequality 2|x - 3| + 6 > 10, we need to isolate the absolute value expression |x - 3|.

We can do this by subtracting 6 from both sides of the inequality:

2|x - 3| > 4

Then we can divide both sides by 2:

|x - 3| > 2

Now we need to consider two cases, one where x - 3 is positive, and another where it is negative:

When x - 3 is positive, the inequality |x - 3| > 2 becomes:

x - 3 > 2

Solving for x gives:

x > 5

When x - 3 is negative, the inequality |x - 3| > 2 becomes:

-(x - 3) > 2

The inequality representing the amount Jeremiah spends on dinner daily is x ≥ $14.50. Two examples of amounts Jeremiah might spend are $16.75 and $22.00.

1. To represent the amount Jeremiah spends on dinner daily, we can use the inequality symbol "≥" (greater than or equal to) since it says "at least." Let's use the variable x to represent the amount.

2. The inequality representing the amount Jeremiah spends is x ≥ $14.50.

3. Example 1: Jeremiah might spend $16.75 on dinner, which satisfies the inequality since $16.75 is greater than $14.50.

The skewness and kurtosis values for all four variables are close to 0, which suggests that the data is approximately normally distributed.

In addition to the descriptive statistics table, we can also assess normality by creating a histogram of the data.

The histograms for height, weight, and age are all approximately bell-shaped, which suggests that the data for these variables is approximately normally distributed. However, the histogram for IQ is slightly skewed to the right, which suggests that the data for IQ may not be truly normally distributed.

The limit as n approaches infinity of ((n+1)⁶-(n-1)⁶)/((n+1)⁵+(n-1)⁵) is 6.

To evaluate the limit as n approaches infinity of the expression ((n+1)⁶-(n-1)⁶)/((n+1)⁵+(n-1)⁵), we can simplify it using algebraic manipulations.

Let's expand the numerator and denominator using the binomial:

Numerator:

((n+1)⁶-(n-1)⁶) = [n⁶ + 6n⁵ + 15n⁴ + 20n³ + 15n² + 6n + 1] - [n⁶ - 6n⁵ + 15n⁴ - 20n³ + 15n² - 6n + 1]

= 12n⁵ + 40n³ + 12n

Denominator:

((n+1)⁵+(n-1)⁵) = [n⁵ + 5n⁴ + 10n³ + 10n² + 5n + 1] + [n⁵ - 5n⁴ + 10n³ - 10n² + 5n - 1]

= 2n⁵ + 20n³ + 2n

Now, let's simplify the expression by canceling out common terms:

((n+1)⁶-(n-1)⁶)/((n+1)⁵+(n-1)⁵) = (12n⁵ + 40n³ + 12n) / (2n⁵ + 20n³ + 2n)

As n approaches infinity, we can see that the highest power of n in the numerator and denominator is n⁵.

We can divide all terms by n⁵ to determine the limit:

lim(n→∞) [(12n⁵ + 40n³ + 12n) / (2n⁵ + 20n³ + 2n)]

= lim(n→∞) [(12 + 40/n² + 12/n⁴) / (2 + 20/n² + 2/n⁴)]

Your friend would need to score at least 46.67% on the final exam to earn a 75% for the course.

Since the final exam counts for 15% of the course grade, the weighted average can be calculated as follows:

Weighted average = (0.85 × 80%) + (0.15 × final exam score)

If we assume that your friend wants to get the highest possible grade, then they would need to get a perfect score on the final exam, which would be 100%.

Plugging this into the equation above, we get:

Weighted average = (0.85 × 80%) + (0.15 × 100%) = 83%

Therefore, the best course grade your friend can earn is 83%.

We can set up an equation where x is the minimum score needed on the final exam:

Weighted average = (0.85 × 80%) + (0.15 × x) = 75%

Simplifying this equation, we get:

0.85 × 80% + 0.15x = 75%

68% + 0.15x = 75%

0.15x = 7%

x = 46.67%

Now, we know that alternate angles are congruent. Thus:
