Explanation:

• Loan Amount = $500

• Time = 2 weeks

• The amount paid pack = $520

We want to determine the simple interest rate.

First, find the amount paid as interest:

The graph of function f(x) = \(2^{x}\) + 3 will be increases without bound As x increases without bound and As x decreases without bound, f(x) approaches the line y = 3 therefore option (C) and (D) will be correct.

A graph is a diametrical representation of any function between the dependent and independent variables.

The graph is easy to understand behavior of the graph.

Given the function,

f(x) = \(2^{x}\) + 3

At x = 0 → f(0) = 2⁰ + 3 = 3

This is an exponential function as shown below which will be increasing as x increase while it will gain the value y = 3 as x decrease.

Hence "The graph of function f(x) = \(2^{x}\) + 3 will be increases without bound As x increases without bound and As x decreases without bound, f(x) approaches the line y = 3".

A.Pirate is more popular with students, but moose is more popular with teachers

Step-by-step explanation:

Its A because majority of students picked pirates and majority of teachers picked moose.

It's not B because the preferences are a lot different between students and teachers.

It's not C because majority of students picked pirates, not moose, and majority of teachers picked moose not pirates.

It's not D because there are more students than teachers so moose is less popular with students, but a lot more popular with teachers even though 15 students picked moose and 15 teachers picked moose. (there are 90 students and 20 teachers)

The number of outcomes if at least 3 tails occur for a fair coin tossed 27 times is 134217700.

Probability is the likelihood or chance that an event will occur.

The formula for calculating probability is expressed as:

Probability = Expected outcome/Total outcome

If a  fair coin is tossed 27 times, the total number of outcomes will be expressed as:

2²⁷ = 134217728

If at least 3 tails occur, the expected outcome will be 27 times.

Pr(at least 3 tails occur) = 2²⁷ - 27 - 1

Pr(at least 3 tails occur) = 134217728 - 28 = 134217700

Hence the number of outcomes if at least 3 tails occur is 134217700.

Answer:

{x  = -1 + √13  ,  x  = -1 - √13}

Step-by-step explanation:

Completing the square:

f(x) = x² + 2x - 12

     = x² + 2x + 1 - 1 - 12

     = (x² + 2x + 1) - 1 - 12

     = (x + 1)² - 13

Solving:

f(x) = 0

⇔ (x + 1)² - 13 = 0

⇔ (x + 1)² = 13

⇔ x + 1 = √13  or  x + 1 = -√13

⇔ x  = -1 + √13  or  x  = -1 - √13

The exchange rate of the euro/pound expressed to four decimal places is 1.0100 euro/pound.

To find the exchange rate of the euro/pound, we can use the given exchange rates of dollar/pound and dollar/euro.

Let's denote the exchange rate of euro/pound as E.

Given:

Exchange rate of dollar/pound = 1.21 dollar/pound

Exchange rate of dollar/euro = 1.22 dollar/euro

To find the exchange rate of euro/pound, we can divide the exchange rate of dollar/euro by the exchange rate of dollar/pound:

E = (Exchange rate of dollar/euro) / (Exchange rate of dollar/pound)

E = 1.22 dollar/euro / 1.21 dollar/pound

Simplifying this expression, we get:

E = 1.01 euro/pound

Therefore, the exchange rate of the euro/pound, is 1.0100 euro/pound.

Therefore, the estimated difference between the cube roots of 343 and 345.1 is approximately 0.0189.

To estimate the difference between the cube roots of 343 and 345.1 using linear approximation, we can use the fact that the derivative of the function f(x) = ∛x is given by f'(x) = 1/(3∛x^2).

Let's start by calculating the cube root of 343:

∛343 = 7

Next, we'll calculate the derivative of the cube root function at x = 343:

f'(343) = 1/(3∛343^2)

= 1/(3∛117,649)

≈ 1/110.91

≈ 0.0090

Using the linear approximation formula:

Δy ≈ f'(a) * Δx

We can substitute the values into the formula:

Δy ≈ 0.0090 * (345.1 - 343)

Calculating the difference:

Δy ≈ 0.0090 * 2.1

≈ 0.0189

$13.73 with tax

tax is 0.73 cents

Step-by-step explanation:

We simply just multiply 13 by 5.6 and get 0.728. Since we are rounding to the nearest CENT we get 0.73!

Answer:

The total would be $13.73

The 97% confidence interval for a sample of 204 soda cans with a mean of 12.05 ounces and a standard deviation of 0.08 ounces is approximately (12.026, 12.074) ounces.

To find the 97% confidence interval, follow these steps:

1. Identify the sample size (n=204), sample mean (X-bar=12.05), and standard deviation (σ=0.08).
2. Determine the appropriate z-score for a 97% confidence interval, which is 2.17 (from a standard normal distribution table).

3. Calculate the standard error (SE) by dividing the standard deviation by the square root of the sample size: SE = σ/√n = 0.08/√204 ≈ 0.0056.

4. Multiply the z-score by the standard error: 2.17 * 0.0056 ≈ 0.0122.

5. Subtract this product from the sample mean for the lower bound: 12.05 - 0.0122 ≈ 12.026.

6. Add this product to the sample mean for the upper bound: 12.05 + 0.0122 ≈ 12.074.

Thus, the 97% confidence interval is approximately (12.026, 12.074) ounces.

The equation of the perpendicular bisector of the line segment with endpoints (-9,-3) and (5,1) is x = -2.

To find the equation of the perpendicular bisector, we first calculate the midpoint of the line segment. The midpoint is given by the average of the x-coordinates and the average of the y-coordinates of the endpoints. In this case, the midpoint is ((-9+5)/2, (-3+1)/2), which simplifies to (-2, -1).

Next, we determine the slope of the line segment. The slope is found by taking the difference in the y-coordinates divided by the difference in the x-coordinates: (1-(-3))/(5-(-9)) = 4/14 = 2/7.

The perpendicular bisector has a slope that is the negative reciprocal of the original line segment's slope. So, the slope of the perpendicular bisector is -7/2.

Finally, using the slope-intercept form of a line (y = mx + b) and substituting the midpoint (-2, -1), we can solve for b. The equation becomes -1 = (-7/2)(-2) + b, which simplifies to -1 = 7 + b. Solving for b, we find b = -8.

Therefore, the equation of the perpendicular bisector is y = (-7/2)x - 8, which can be simplified to 2x + 7y + 16 = 0.
