A. The equation that can be used to determine the number of weeks is $999=225+42w

B. The number of weeks it will take Hannah to repay is 18weeks

An equation is a mathematical statement, which has an equal sign (=) between the algebraic expression. Linear equations are the equations of degree 1. It is the equation for the straight line. The solutions of linear equations will generate values, which when substituted for the unknown values, make the equation true. In the case of one variable, there is only one solution. For example, the equation x + 3 = 0 has only one solution as x = -2.

the total amount of money Hannah repaid is $225+$43×w, where w is the number of weeks to repay $43.

therefore $999= $225+$43w

$43w=$ (999+225)

$43w= $1224

divide both side by $43

w= $1224/$43

w= 18 weeks

therefore it will take Hannah 18weeks to repay the money.

Answer:

9) JI=41

8) A

Step-by-step explanation:

Question 1:

We know that DE=GF, so that means that HJ=JI.

We can substitute in the values into an equivalent equation:

3x+20=15x-64

solve for x by adding 64 to both sides

3x+84=15x

subtract 3x from both sides

84=12x

divide both sides by 12

x=7

Then we can substitute 7 for x in the equation:

15x-64

15(7)-64

simplify

41

So, JI=41

Question 2:

The general (standard) form of an equation is:

\((x-h)^{2} + (x-k)^{2} =r^{2}\)

The percentage of the students who weigh more than 125 lbs is 50%.

The question asks to find the percentage of female students who weigh more than 125 lbs. As we know, the second quartile is the median, which means half the students weigh less than 125 lbs, and the other half weigh more than 125 lbs.

Therefore, the answer is 50%.

The quartile is a mathematical concept used in statistics that divides an ordered data set into four equal parts.

The first quartile, Q1, divides the lowest 25% of the data from the rest;

The second quartile, Q2, is the median, or the middle value of the data; and

The third quartile, Q3, divides the upper 25% of the data from the rest.

Let’s discuss the given information. The 1st, 2nd, and 3rd quartiles of female students' weight at a major university are 95 lbs., 125 lbs., and 138 lbs. respectively.

Here, the 2nd quartile i.e., 125 is the median value.

Therefore, half of the female students at a major university weigh less than or equal to 125 lbs, and the other half of the female students weigh more than or equal to 125 lbs.

So, the percentage of students who weigh more than 125 lbs is 50%.

The maximum likelihood estimate for the bias of the coin is 1/3.

The maximum likelihood estimate for the bias of the coin is the proportion of times it came up heads, which is 10/30 or 1/3.

The idea behind maximum likelihood estimation is to find the value of the parameter (in this case, the bias of the coin) that makes the observed data (in this case, the number of heads and tails) the most likely to occur.

In other words, we want to find the value of the parameter that maximizes the likelihood function.

For a coin flip, the probability of getting heads is p and the probability of getting tails is 1-p. The likelihood function for observing 10 heads and 20 tails is:

\(L(p) = (p)^{10} * (1-p)^{20}\)

To find the maximum likelihood estimate, we take the derivative of the likelihood function with respect to p and set it equal to zero:

\(d/dp [L(p)] = 10*(p)^9*(1-p)^20 - 20*(p)^{10}*(1-p)^{19} = 0\)

Solving for p, we get:

p = 1/3

Therefore, the maximum likelihood estimate for the bias of the coin is 1/3.

The right response is that the two linear equation never intersect , because the graph of these two linear equation will be two parallel lines.

How many types of solution are there for two linear equations ?

There are 2 types of solution :
Consistent :

A consistent system is said to be an independent system if it has a single solution.

A consistent system is said to be a dependent system if the equations have the same slope and the same y-intercepts. In other words, the lines coincide, so the equations represent the same line. Each point on the line represents a pair of coordinates that fits the system. So there are an infinite number of solutions.

Non-consistent :

Another type of system of linear equations is the inconsistent system, in which the equations represent two parallel lines. The lines have the same slope and different y-intercepts. There are no common points for both lines; therefore, there is no solution to the system and if we draw the graph of these equations then the graphs of both equation becomes parallel to each other.

The two linear equations never intersect.

When a system of two linear equations in two variables has no solution, it means that there is no set of values for the variables that satisfies both equations simultaneously. Geometrically, this corresponds to the two lines represented by the equations being parallel. Since parallel lines never intersect, the statement "The two linear equations never intersect" accurately describes the situation.

If the two linear equations were graphed on a coordinate plane, they would appear as two distinct lines that run parallel to each other without ever crossing or intersecting. This indicates that there is no common point of intersection between the lines, and therefore no solution exists for the system of equations.

It is important to note that this scenario is different from the case where the two linear equations represent the same line. In that case, the equations would be equivalent, and every point on the line would satisfy both equations. However, when there is no solution, it means that the lines do not share any common points and never intersect.

The simplified form of the trigonometric expression (1 - sin θ)(1 + sin θ) csc²θ + 1 is cos²θ.

We can start by simplifying the expression (1 - sin θ)(1 + sin θ) by using the identity (a - b)(a + b) = a² - b². Applying this identity, we have (1 - sin θ)(1 + sin θ) = 1² - (sin θ)² = 1 - sin²θ.

Next, we simplify the term csc²θ, which is the reciprocal of the square of the sine function. The reciprocal of sin θ is csc θ, so csc²θ can be rewritten as (1/sin θ)² = 1/sin²θ.

Combining the simplified expressions, we have (1 - sin²θ)(1/sin²θ) + 1. Notice that (1 - sin²θ) is equivalent to cos²θ using the Pythagorean identity sin²θ + cos²θ = 1.

Therefore, the final simplified expression is cos²θ + 1.

The margin of error for the 99% confidence interval for the population mean of grass seed germination periods is approximately 3.374 days.

To find the margin of error for the confidence interval for the population mean with a 99% confidence level for germination periods of grass seed, follow these steps:

1. Identify the given information:
- Sample size (n) = 21
- Sample mean (x) = 34 days
- Population standard deviation (σ) = 6 days
- Confidence level = 99%

2. Determine the appropriate z-score for the 99% confidence level:
- Since the confidence level is 99%, we need to look for the z-value that corresponds to 0.005 in the z-table (because 1 - 0.99 = 0.01, and 0.01/2 = 0.005).
- z0.005 = 2.576

3. Calculate the standard error of the mean (SEM):
- SEM = σ/√n = 6/√21 = 1.31

4. Calculate the margin of error (ME):
- ME = z * SEM = 2.576 * 1.31 = 3.374

5. Round the answer to three decimal places:
- ME = 3.374

Your answer: The margin of error for the 99% confidence interval for the population mean of grass seed germination periods is approximately 3.374 days.
