Answer:

Tahlia was correct in remembering that you can find the slope of a line using the slope formula.

She was also correct that the slope is 0.5.

However, if you use the slope-intercept formula y = mx + b, you still have to find b (the y-intercept) by plugging in one of the two points and the slope.

So, if we plug in the first point and the slope into the line, we can find b and thus the full equation of the line:

[tex]-7.5=0.5(-3)+b\\-7.5=-1.5+b\\b=-6\\\\y=0.5x-6[/tex]

Using a standard normal distribution table, the value of z₀ is -0.64

To find z₀, we need to use the standard normal distribution table or calculator. We know that the area under the standard normal curve between z₀ and 2.2 is 0.7258.

Using a standard normal distribution table or calculator, we can find the z-score corresponding to 0.7258.

From the table, we can find that the closest value to 0.7258 is 0.7257, and the corresponding z-score is approximately 0.61.

Therefore, we have:

P(z₀ < z < 2.2) = 0.7258

P(z < 2.2) - P(z < z₀) = 0.7258

Using the z-score table again, we can find that P(z < 2.2) is approximately 0.9861.

So we have:

0.9861 - P(z < z₀) = 0.7258

P(z < z₀) = 0.2603

Using the z-score table again, we can find that the z-score corresponding to 0.2603 is approximately -0.64.

Therefore, we have:

z₀ = -0.64

Rounding to at least four decimal places, we get:

z₀ = -0.6400

The response to the given question would be that Because it has a interest higher interest rate and a longer term than option 3, option 1 would generate the greatest interest.

By dividing the principal by the interest rate, the passage of time, and other factors, simple interest is determined. Simple return equals principle plus interest plus hours is the formula used in marketing. The easiest way to compute interest is by using this method. The most typical method for calculating interest is as a portion of the principle amount. For example, if he borrows $100 from a buddy and agrees to pay back the loan at 5% interest, he will only pay his share of the 100% interest. $100 (0.05) = $5. When you borrow money, you must pay interest, and you must charge interest when you lend it. Typically, interest is determined as an annual percentage of the loan total. The interest rate of the loan is defined as this ratio.

The following would be the order of 2000 simple interest generated on an investment, from least to most:

2000 invested for 20 years at 3% simple interest

2000 invested for three years at 10% simple interest

2000 invested at 10% simple interest for nine years

Because of its longer length and lower interest rate than the other two alternatives, Option 2 would yield the least amount of interest.

Due to its higher interest rate and longer period, option 3 would generate more interest than option 2.

Because it has a higher interest rate and a longer term than option 3, option 1 would generate the greatest interest.

The sample suggests that the true mean is likely to be between 98.0°F and 98.2°F, which is lower than 98.6°F.  98.6°F overestimates the mean body temperature of all healthy humans.

Standard deviation is defined as the measure of how spread out numbers are. It measures the average distance between each number in a set of data and the mean. It is used to measure the variation and dispersion of a set of data from its mean.

A 99% confidence interval estimate of the mean body temperature for all healthy humans can be calculated using the following formula: mean ± 2*standard deviation/square root of the sample size. In this case, the confidence interval is 98.1°F ± 0.12°F. This means that the mean body temperature of all healthy humans is likely to be between 98.0°F and 98.2°F.

Using the Pythagorean theorem we know that the rest 2 sides of the given right triangle are 27 inches long.

The longest side of a right-angled triangle, or the side opposite the right angle, is known as the hypotenuse in geometry.

The Pythagorean theorem, which asserts that the square of the length of the hypotenuse equals the sum of the squares of the lengths of the other two sides, can be used to determine the length of the hypotenuse.

The side opposite the right angle is always the hypotenuse of a right triangle. In a right triangle, it is the longest side.

So, we know the Pythagorean theorem which is:

H² = a² + b²

We know that:

H² = a² + b²

54² = a² + b²

Suppose that the given right triangle is also an isosceles triangle with the rest of the sides being of the same length. Then,

54/2 = 27

Similarly,

54² = a² + b²

54² = 27² + 27²

Therefore, using the Pythagorean theorem we know that the rest 2 sides of the given right triangle are 27 inches long.

The inequality 2d+20<=120 is a valid inequality. It means that some value of d can be substituted into the inequality to make it a true statement.

In mathematics, an inequality is a statement that compares two values and indicates how they are related in terms of magnitude or size. Inequalities use symbols such as "<" (less than), ">" (greater than), "<=" (less than or equal to), ">=" (greater than or equal to), or "≠" (not equal to) to show the relationship between the two values.

In the given question,

Yes, the inequality 2d+20<=120 is a valid inequality. It means that some value of d can be substituted into the inequality to make it a true statement.

In this case, the inequality is saying that 2 times the value of d plus 20 is less than or equal to 120. To solve for d, we can subtract 20 from both sides to get:

2d <= 100

Then, we can divide both sides by 2 to isolate d:

d <= 50

So the solution to the inequality is that d must be less than or equal to 50 for the inequality to be true.

If the woman receives $24 per day, the amount of the man's daily wage will be $42.

In mathematics, a ratio shows how many times one number contains another. Its says how much of one thing there is compared to another thing.

Let m be the man's hourly wage

Let w be the woman's hourly wage

We are told that the woman's daily wage is $24, which we can express in terms of her hourly wage as: w * 8 = $24

Solving for w, we get:

w = $24 / 8

w = $3

We are also told that the ratio of the man's hourly wage to the woman's hourly wage is 7:5, which we can express as: m / w = 7 / 5

Substituting w = $3, we get:

m / 3 = 7 / 5

Solving for m, we get:

m = (7 / 5) * 3

m = $4.20

Given cos, you will have to use this to calculate sin because csc is  1/ sin

Remember    cos^2 + sin^2 = 1

                        (2/5)^2 + sin^2 = 1

                                  sin^2 = 21/25  

                                    sin = sqrt (21) / 5     (ignoring negative root)

csc = 1/sin = 5 / sqrt(21)

We simplify the summation to get:

S₄ = 8*(3ⁿ⁻¹)

Remember that the large sigma means that we need to add from the lower number to the larger number.

The particular problem here is that "n" is not the index in the summation, so we can't evaluate that variable, we will just have 4 terms (for k = 1 to k = 4) but the variable k does not appear, so we will  have 4 times the same term:

S₄ = 2*(3ⁿ⁻¹) +  2*(3ⁿ⁻¹) +  2*(3ⁿ⁻¹) +  2*(3ⁿ⁻¹)

S₄ = 4*2*(3ⁿ⁻¹)

S₄ = 8*(3ⁿ⁻¹)

The function h(x) has two parts:

For x < -3, the value of h(x) is J-4.

For x >= -3, the value of h(x) is x-3.

To plot this on a graph, you would need to draw a vertical line at x = -3 to separate the two parts of the function. Then, for x < -3, you would plot a horizontal line at a height of J-4 to represent the constant value of h(x) in that region. For x >= -3, you would plot the line y = x-3.

The variability of the mean is 0.154

The total of all values divided by all of the values constitutes the result of a set, also called as the arithmetic mean. It is considered to be the most popular central trend indicator, and the word "mean" is commonly used to describe it. The average of a figure is known to as the average.

We are Given a normal distribution, the MAD and standard deviation (SD) are roughly inversely proportional to one another as follows:

=> MAD = 1.4826 × SD

Here we can calculate the standard deviation as follows:

=> SD = MAD / 1.4826

Since the MAD in this instance is provided as 3.2,

=> SD ≈ 3.2 / 1.4826 ≈ 2.16

The standard error of the mean (SEM), can be determined as follows, then gives the variability of the mean.

Let's say the cost to rent each chair is "x" and the cost to rent each table is "y". Then we can set up two equations based on the given information:

3x + 2y = 21 (for the first rental)

8x + 4y = 45 (for the second rental)

We can simplify the second equation by dividing both sides by 4:

2x + y = 11.25

Now we have two equations with two variables, which we can solve using substitution or elimination. Let's use substitution:

3x + 2y = 21

2x + y = 11.25

From the second equation, we can solve for y in terms of x:

y = 11.25 - 2x

Then we can substitute this expression for y in the first equation:

3x + 2(11.25 - 2x) = 21

Simplifying and solving for x, we get:

3x + 22.5 - 4x = 21

-x + 22.5 = 21

-x = -1.5

x = 1.5

So the cost to rent each chair is $1.50. We can substitute this value back into either of the original equations to solve for y:

3(1.5) + 2y = 21

4.5 + 2y = 21

2y = 16.5

y = 8.25

So the cost to rent each table is $8.25. Therefore, the answer is $1.50 for each chair and $8.25 for each table.
