Given is a table as shown in the question.

Assume the exponential equation to be -

y = A(B)ˣ

At [x] = 0, [y] = 12 -

12 = A(B)⁰

A = 12

and

At [x] = 2, [y] = 15 -

15 = A(B)²

(B)² = 15/12

(B)² = 1.25

(B) = √(1.25)

Answer:

The sales tax rate is 7.96%.

Step-by-step explanation:

To determine the sales tax rate, we need to first calculate the amount of the discount on the tablet by multiplying the regular price by the discount percentage:

Discount = Regular price * Discount percentage

Discount = $330 * 15%

Discount = $49.50

Next, we can calculate the total price of the tablet before taxes by subtracting the discount from the regular price:

Total price before taxes = Regular price - Discount

Total price before taxes = $330 - $49.50

Total price before taxes = $280.50

Finally, we can calculate the sales tax rate by dividing the total amount of taxes paid by the total price of the tablet before taxes and multiplying by 100% to express the result as a percentage:

Sales tax rate = (Total amount of taxes paid / Total price before taxes) * 100%

Sales tax rate = ($302.94 - $280.50) / $280.50 * 100%

Sales tax rate = $22.44 / $280.50 * 100%

Sales tax rate = 7.96%

Therefore, the sales tax rate is 7.96%.

Step-by-step explanation:

We can use the confidence interval formula to estimate how much the drug will lower a typical patient's systolic blood pressure with 80% confidence.

The confidence interval formula is:

Sample mean ± (t-score × standard error)

Where the t-score is calculated from the t-distribution using the number of degrees of freedom (n-1) and the confidence level (80%).

Using the given information, we can calculate the t-score as follows:

t-score = 1.711 (for 80% confidence level and 28 degrees of freedom)

Therefore, the confidence interval is:

55.9 ± (1.711 × (7.4/√29))

= 55.9 ± 4.125

So, with 80% confidence, we can say that the drug will lower a typical patient's systolic blood pressure by between 51.8 and 60.0.

Answer: The solution here is found by establishing a system of linear equations.

A system of equations with x unknowns can be evaluated for an exact solution if the system has x equations.

Within the question, we are asked to discover the values of two different unknowns - dimes and nickels.

Therefore, we'll need two equations to obtain an exact solution, both of these will come directly from the problem itself.

Let d represent the number of dimes Diane has and let n represent the number of nickels.

Equation 1

We know from the given information that the total number of coins (both dimes and nickels) is equal to 19.

Subsequently, we can generate the equation d + n = 19.

Equation 2

We know that the individual value of a dime is $0.10 or 0.1 dollars, therefore the total value of the dimes is equal to the individual value of a dime multiplied by the total number of dimes.

The resultant expression for the total value of the dimes is (0.1)*d

We know that the individual value of a nickel is $0.05 or 0.05 dollars, therefore the total value of the nickels is equal to the individual value of a nickel multiplied by the total number of nickels.

The resultant expression for the total value of the nickels is (0.05)*n

We know that Diane only has dimes and nickels, and the total value of all her coins must be equal to the total value of the dimes plus the total value of the nickels. This value is given within the problem to be $1.55 or 1.55 dollars.

Subsequently, our second equation within the system is (0.1)*d + (0.05)*n = 1.55.

Now, we can solve the system of equations using whichever means is most convenient. For this example, I will solve the system by substitution

First, solve for one of the variables —> Equation 1 —> d + n = 19 —> d = 19 - n

Second, substitute the value of d into Equation 2 —> (0.1)*(19 - n) + (0.05)*n = 1.55

Recall that 0.1 = 1/10 and 0.05 = 1/20

Equation 2 —> (1/10)*19 - (1/10)*n + (1/20)*n = (31/20) —> (19/10) - (n/10) + (n/20) = (31/20)

Find the least common denominator of all fractions in the equation (20 in this case), convert the fractions to have like denominators, and solve.

(19/10)*(2/2) - (n/10)*(2/2) + (n/20) = (31/20) —> (38/20) - (2n/20) + (n/20) = (31/20) —> (38/20) - (n/20) = (31/20) —> (n/20) =(38/20) - (31/20) =(7/20) —>n = 7

Substitute solution into Equation 1 to solve for d

d + 7 = 19 —> d = 12

q+4+q + 10q+40 + 25q = 155

37q + 44 = 155

37q = 111

q = 3 (# of quarters)

d = q+4 = 7 (# of dimes)

p = d+q = 7+3 = 10 (# of pennies)

As we know that;

A system is consistent if it has at least one solution. A consistent system is dependent if there are an endless number of possible solutions. Both equations show the same line on a graph when you plot the equations.

A inconsistent system has no solution. There is no solution because the graphs of the lines do not connect, making the graphs parallel.

Even if the vertices of two graphs differ or are rearranged, we will pronounce them equivalent if they have the same edge structure.

Answer:

Step-by-step explanation:

We have two types of textbooks. Let's use "x" to represent the number of math textbooks and "y" to represent the number of history textbooks.

Altogether, the bookseller sold 240 math and history textbooks. So:

x + y = 240

Now, the number of history textbooks sold was 72 less than the number of math books sold. So:

y = x - 72

Now we can substitute for y in the equation and solve:

x + y = 240

x + (x - 72) = 240

2x - 72 = 240

2x = 312

x = 156

The bookseller sold 156 math textbooks.

Since y = x - 72, he must have sold 84 history textbooks.

Let's check our answers:

x + y = 240

156 + 84 = 240

That is true, so we did get the correct answers

The marginal rate of substitution (MRS) is a measure of how much of one good an individual is willing to give up in exchange for another good. In other words, it represents the slope of the indifference curve at a given point.

If Victoria's indifference curves are bowed outward, it means that as she moves from right to left along the horizontal axis, the MRS will decrease. This is because as she consumes more of one good, she becomes less willing to give up units of the other good in exchange. The MRS will continue to decrease until it reaches its minimum value at the point where the indifference curve is tangent to the budget line.

It's important to note that the MRS will only decrease if Victoria's indifference curves satisfy the other three properties of indifference curves:

If Victoria's indifference curves do not satisfy these properties, it is not possible to accurately determine the behavior of her MRS as she moves from right to left along the horizontal axis.

Step-by-step explanation:

The sum is 182.5, which is 200 to 1 significant figure.

The pooled proportion is 0.200 and the standard error of the difference in the proportions is 0.0201.

1. The null hypothesis is Pu-Po = 0, which means that the proportion of people under 18 who had accidents is the same as the proportion of people over 18 who had accidents.

2. To calculate the pooled proportion, we first add the total number of people in each group (500 + 600 = 1100). Then we add the total number of accidents in each group (180 + 150 = 330). Finally, we divide the total number of accidents by the total number of people to get the pooled proportion (330/1100 = 0.200).

3. The standard error of the difference in the proportions can be calculated using the formula SE = SQRT(P1*(1-P1)/n1 + P2*(1-P2)/n2), where P1 is the proportion of people under 18 who had accidents, P2 is the proportion of people over 18 who had accidents, and n1 and n2 are the number of people in each group. In this case, P1 = 150/600 = 0.250, P2 = 180/500 = 0.360, n1 = 600, and n2 = 500. Plugging these values into the formula gives us SE = SQRT(0.250*(1-0.250)/600 + 0.360*(1-0.360)/500) = 0.0201.

b) m = 6, n = 9.

c) m = 12, n = 180.

d) m = -7/2, n = 49/16.

Perfect square trinomials are expressions that have either of these two formats:

The term that multiplies x is always the multiplication of 2 by both of the two terms that are added.

Hence in item 1, the expression is completed as follows:

x² - 10x = (x - 5)² - 25 = x² - 10x + 25 - 25

Meaning that m = -10, n = 25.

In item 2, the expression is completed as follows:

x² + 6x = (x + 3)² - 9 = x² + 6x + 9 - 9.

Hence m = 6, n = 9.

In item 3, the expression is completed as follows:

5x² + 60x = 5(x² + 12x) = 5(x + 6)² - 180 = 5(x² + 12x + 36) - 180 = 5(x² + 12x + 180 - 180).

Hence m = 12, n = 180.

In item 4, the expression is completed as follows:

2x² - 7x = 2(x² - 7/2x) = 2(x² - 7/4x)² - 49/32 = (2x² - 7/2x + 49/16 - 49/16).
