$1000 is 71.43 percent of the credit limit.

To lower the debt to credit limit ratio by $1000, you have a few options. The first option is to increase your credit limit by requesting a higher limit from your credit card issuer. Alternatively, you can pay off some of your outstanding balance to reduce your debt. Either way, it's important to make sure you're not maxing out your credit limit, as this can negatively impact your credit score.

It's also a good idea to review your spending habits and create a budget to ensure you're not overspending and accumulating debt. By making responsible financial decisions and managing your credit wisely, you can improve your credit score and achieve your financial goals.

To calculate the percentage of $1000 in terms of the credit limit of $1400, we need to divide $1000 by $1400 and multiply the result by 100. This gives us,

($1000 / $1400) x 100 = 71.43%

Therefore, $1000 is approximately 71.43% of the credit limit of $1400.

Step-by-step explanation:

The scale factor is 0.6. Then the area of the actual garage is 19.44 m². And dimensions are 3.6 m and 5.4 m.

Scale factor means the changing of the size of the object without changing the shape. The size of the object may be increased or decreased based on the scale factor.

Given

A scale model drawing of a garage is 6 centimeters wide and 9 centimeters long.

The scale model uses a scale in which 3 centimeters represent 1.8 meters.

The scale factor will be

\(\rm 1 \ cm = 0.6\) m

Then the dimension of the actual garage will be

Length = 0.6 x 6 = 3.6 m

 Width = 0.6 x 9 = 5.4 m

Then the area of the actual garage will be

Area of garage = Length x Width

Area of garage = 3.6 x 5.4

Area of garage = 19.44 m²

Thus, the area of the actual garage is 19.44 m². And dimensions are 3.6 m and 5.4 m.

Yes, the true mean of 33 is within the margin of error of the sample mean, we can conclude that the confidence interval does contain the true mean.

To determine whether the confidence interval contains the true mean of 33, we need to calculate the margin of error for the confidence interval. The margin of error is a measure of the precision of the estimate, and it is calculated using the sample size, the standard deviation of the population, and the desired level of confidence.

For a 95% confidence interval, the margin of error can be calculated using the following formula:

The margin of error = 1.96 * (standard deviation / √sample size)

Plugging in the values, we get:

Margin of error = 1.96 * (14 / √42)

Performing the calculation, we find that the margin of error is 3.39. This means that the sample mean of 31 is likely to be within 3.39 units of the true mean, with a confidence level of 95%.

Since the true mean of 33 is within the margin of error of the sample mean, we can conclude that the confidence interval does contain the true mean. This means that our estimate of the population mean, based on the sample size 42, is likely to be accurate.

9, 23, 45, 75, 113, 159

Step-by-step explanation:

Quadratic Sequence

The difference between two consecutive terms of a quadratic sequence is another sequence, this one is an arithmetic sequence.

The first terms are given as:

9, 23, 45, 75, ...

Let's compute the differences:

23 -  9  = 14

45 - 23 = 22

75 - 45 = 30

Note the differences form an aritmetic sequence of commons difference 8.

The next two terms will be formed adding 8 to the previous difference, that is:

30 + 8 = 38 is the next difference. And the next term is

75 + 38 = 113

38 + 8 = 46 is the next difference, and the next term is

To model the relationship between Vreel's rews and corazs, we can set up a system of equations in standard form.

The standard form of a linear equation is Ax + By = C, where A, B, and C are constants and x and y are variables.

We know that Vreel purchased a total of 22 rews and corazs, and that the rews cost $8 each and the corazs cost $3 each. We can use this information to set up the following two equations:

The first equation represents the total cost of the rews: 8x + 0y = 96

The second equation represents the total number of rews and corazs that Vreel purchased: 1x + 1y = 22

Together, these two equations form a system of equations that can be used to model the relationship between Vreel's rews and corazs.

We do not have enough evidence to conclude that the true mean melting point differs from 95 at a significance level of 0.01.

To determine if the true mean melting point differs from 95, we can use a one-sample t-test with a significance level of 0.01.

The null hypothesis is that the true mean melting point is equal to 95, and the alternative hypothesis is that the true mean melting point is different from 95.

We can calculate the t-statistic using the formula:

t = (sample mean - hypothesized mean) / (sample standard deviation / sqrt(sample size))

where sample size is 16, sample mean is 94.32, hypothesized mean is 95, and sample standard deviation is the same as the population standard deviation of 1.20.

Plugging in these values, we get:

\(t = (94.32 - 95) / (1.20 / \sqrt{(16)} ) = -2.6667\)

Using a t-distribution table with 15 degrees of freedom (n-1=16-1), and a two-tailed test at a significance level of 0.01, the critical t-value is ±2.947.

Since our calculated t-value of -2.6667 falls within the acceptance region (-2.947 < -2.6667 < 2.947), we fail to reject the null hypothesis.

Bag A contains 3 red balls and 1 blue ball. a bag b contains 1 red ball and 1 blue ball. a ball is randomly picked from each bag. the ball from bag A is then placed into bag b and the ball from bag b is placed into bag A. On average, we can expect bag A to have 5/8 red balls after the switch.

To calculate the expected number of red balls in bag A, we need to consider all the possible outcomes and their probabilities.
First, we can determine the probability of picking a red ball from bag A, which is 3/4. The probability of picking a blue ball from bag A is 1/4. Similarly, the probability of picking a red ball from bag B is 1/2, and the probability of picking a blue ball from bag B is also 1/2.
Next, we need to consider all the possible outcomes of switching the balls between the bags. If we pick a red ball from bag A and a blue ball from bag B, we will switch them so that bag A now has 2 red balls and 1 blue ball, while bag B has 2 blue balls. If we pick a blue ball from bag A and a red ball from bag B, we will switch them so that bag A still has 3 red balls and 1 blue ball, while bag B now has 1 red ball and 2 blue balls.
Therefore, the expected number of red balls in bag A can be calculated as follows:
(3/4 x 1/2) x 2 red balls + (1/4 x 1/2) x 3 red balls = 5/8 red balls

A(r) = l*w ( in m² )    where l is the length in m   and w is the width in m

If we have:  A(r)  =  x² - 6*x  - 7 (m²), as an area of a rectangle, then we can factoring the equation, and get the rectangle dimensions, then:

x²  - 6*x  -  7  =  ( x  - 1 ) * ( x - 7 ) = area of the rectangle in m²

As problem statement establishes that ( x - 7 ) ( m)  is the width, then

Answer:

'x' only has one solution

Step-by-step explanation:

First multiply both sides by 'x^2'

40x = -5x^2

(bring both values to one side and factorize to solve for 'x')

5x^2 +40x=0

5x(x+8)=0

5x= 0 ; x+8 = 0

x=0 ; x=-8

x cannot equal to '0' as zero cannot be a denominator.

Hence, x=-8 is the only correct solution.

So, 'x' only has one solution.

PT = 17

Step-by-step explanation:

Since T is the midpoint of PQ, then

PT = TQ , substitute values

4x + 5 = 8x - 7 ( subtract 4x from both sides )

5 = 4x - 7 ( add 7 to both sides )

12 = 4x ( divide both sides by 4 )

3 = x

Thus

PT = 4x + 5 = 4(3) + 5 = 12 + 5 = 17

Answer:

17

Step-by-step explanation:

since T is mid point of PQ

PT=TQ

\(4x + 5 = 8x - 7 \\ 5 + 7 = 8x - 4x \\ 12 = 4x \\ x = 12 \div 4 \\ x = 3 \\ \)

so

\(pt = 4x + 5 \\ = 4(3) + 5 \\ = 12 + 5 \\ pt = 17\)

By decreasing 'a', we are reducing the vertical distance between the highest and lowest points of the graph, effectively compressing it vertically.

To compress the graph vertically, we need to make the amplitude of the function smaller.

To compress the graph of the function y = asin(bx) vertically, we need to decrease the value of 'a'. This is because the value of 'a' represents the amplitude of the function, which determines the vertical stretch or compression.

It is important to note that 'b' does not affect the vertical compression; it only controls the horizontal stretch or compression.

It is true that the existence of two local maxima does not guarantee the presence of a local minimum. It is possible for a function to have multiple local maxima and no local minimum.

For example, consider the function f(x,y) = x^4 - 4x^2 + y^2. This function has two local maxima at (2,0) and (-2,0), but no local minimum. Therefore, the statement "if f(x,y) has two local maximal, then f must have a local minimum" is false. The presence or absence of local maxima and minima depends on the behavior of the function in the immediate vicinity of a point, and cannot be determined solely based on the number of local maxima. It is possible for a function to have an infinite number of local maxima and minima, or none at all. Therefore, it is important to carefully analyze the behavior of a function in order to determine the presence or absence of local extrema.

The probability of choosing a yellow tile as the second tile given that the first tile was blue is the same as the chance of choosing a yellow tile as the second tile given that the first tile was yellow when the tiles are chosen without replacement.

This is so that the distribution of the other tiles is unaffected when a blue tile is chosen first. Likewise, choosing a yellow tile first has no impact on how the other tiles are distributed.

The probabilities are unchanged despite the independence of the events. Therefore:

P(blue first | yellow second) = P(blue first | yellow second)

The likelihood of choosing a yellow tile as the second tile is the same in both scenarios.

P(blue first | yellow second) = P(blue first | yellow second)
