I just started learning about rate and I am stuck on a question.(A watch keeps perfect time but only has an hour hand. If the hour hand is three fifths of the distance between 1and2, determine the actual time in hours and minutes)

Answer:

w=3

Step-by-step explanation:

\( \frac{2w - 1}{5} + w + 2 = 2w \\ \frac{2w - 1 + 5w + 10}{5} = 2w \\ 7w + 9 = 10w \\ 9 = 10w - 7w \\ 9 = 3w \\ w = 3\)

When the population standard deviation is unknown and the sample size is less than 30, we need to use the t-distribution to compute a confidence interval for the mean, and we should consult a t-table to find the appropriate t-value based on the degrees of freedom and the desired level of confidence.

When the population standard deviation is unknown and the sample size is less than 30, we need to use the t-distribution to compute a confidence interval for the mean.

The t-distribution is similar to the standard normal distribution, but with heavier tails, and it is used when the population standard deviation is unknown.

To compute the confidence interval for the mean using the t-distribution, we need to find the appropriate t-value from a t-table. The t-table provides critical values for different degrees of freedom and levels of confidence.

The degrees of freedom for a t-distribution with a sample size of n is (n-1). For example, if we have a sample size of 20, the degrees of freedom would be 19.

To find the appropriate t-value from the t-table, we need to know the degrees of freedom and the desired level of confidence. For example, if we have a sample size of 20 and want to calculate a 95% confidence interval, we would look for the t-value with 19 degrees of freedom and 0.025 (0.05/2) in the middle of the table. This t-value would be used in the formula to calculate the confidence interval for the mean.

To determine the number of different committees that are possible, we need to calculate the total number of combinations of people for each job on the committee which will be 55,440.

For the chair position, we have 12 people to choose from. So, we have 12 choices for the chair. For the three hagglers, we need to choose 3 people out of the remaining 11 (excluding the chair). This can be calculated using the combination formula: C(11, 3) = 165. Therefore, we have 165 choices for the hagglers.

For the six do-nothings, we need to choose 6 people out of the remaining 8 (excluding the chair and the hagglers). This can be calculated using the combination formula: C(8, 6) = 28. Therefore, we have 28 choices for the do-nothings. To calculate the total number of different committees, we multiply the number of choices for each position.

Total number of committees = (Number of choices for chair) * (Number of choices for hagglers) * (Number of choices for do-nothings)

= 12 * 165 * 28

= 55,440

The linear equation that represents the relationship between the number of shirts sold (n) and the price per shirt (p) is p = -0.002n + 27.

To find the linear equation in the form p = mn + b, we can use the given historical data points and solve for the slope (m) and y-intercept (b).

The first data point states that 5000 shirts can be sold at a price of $17. We can represent this as the ordered pair (5000, 17).

The second data point states that 7000 shirts can be sold at a price of $9. This can be represented as the ordered pair (7000, 9).

To find the slope (m), we can use the formula:

m = (p2 - p1) / (n2 - n1)

Substituting the values from the two data points, we get:

m = (9 - 17) / (7000 - 5000)

m = -8 / 2000

m = -0.004

Rounding this slope to three decimal places, we have m ≈ -0.004.

To find the y-intercept (b), we can use one of the ordered pairs and substitute the values into the equation p = mn + b. Let's use the first data point (5000, 17):

17 = -0.004(5000) + b

Simplifying the equation, we have:

17 = -20 + b

b = 37

Therefore, the y-intercept (b) is 37.

Now we can write the linear equation in the form p = mn + b using the calculated values:

p = -0.004n + 37

However, we need to round the slope to three decimal places, so the final linear equation representing the relationship between the number of shirts sold (n) and the price per shirt (p) is:

p = -0.002n + 37

Thus, the linear equation representing the relationship between the number of shirts sold and the price per shirt is p = -0.002n + 37.

The equation that represents the line that passes through the point (6, −3) and has a slope of one half is 2y - x = 13.

The equation of a line is represented as,

y = mx + c                                       equation1

x and y are the coordinates of the point from where the line is passing and m is the slope of the line.

As per the question the line is passing from the point (6, -3). This means value of x = 6 and that of y = -3. The slope of line is (1/2), means m = (1/2).

The slope of the line through the point (-1,6) can also be written as   (y - 6)/(x - (-1))  =  (y-6)/(x+1).

i.e., m = (y-6)/(x+1)

On equating both the values of m, we will get

(y-6)/(x+1) = 1/2

On simplifying, we get

2y - 12 = x +1

or  2y - x = 13

The equation that represents the line that passes through the point (6, −3) and has a slope of one half is 2y - x = 13.

C)The greatest number is 8.2 × 10-3. It is 2,000 times greater than the smallest number.

In scientific notation, a number is written as the product of a number between 1 and 10 and a power of 10. The power of 10 tells us how many places to move the decimal point to the right (if the exponent is positive) or to the left (if the exponent is negative).

In this case, 8.2 × 10-3 means 8.2 × (10^-3) = 0.0082, 5.2 × 10-6 means 5.2 × (10^-6) = 0.0000052 and 4.1 × 10-6 means 4.1 × (10^-6) = 0.0000041.

To compare the numbers, we can compare the coefficient or the number in front of the 10 power. We can see that 8.2 is greater than 5.2 and 4.1. To check how many times greater the smallest number is, we can use the following formula: (greatest number / smallest number) = (8.2 / 0.0000041) = 2,000

Therefore, the greatest number is 8.2 × 10-3 and it is 2,000 times greater than the smallest number.

The statement that shows equivalent measurements is "52 meters = 520 decimeters." Option C.

To determine the equivalent measurements, we need to understand the relationship between different metric units.

In the metric system, each unit is related to others by factors of 10, where prefixes indicate the magnitude. For example, "deci-" represents one-tenth (1/10), "centi-" represents one-hundredth (1/100), and "kilo-" represents one thousand (1,000).

Let's analyze each statement:

5.2 meters = 0.52 centimeters: This statement is incorrect. One meter is equal to 100 centimeters, so 5.2 meters would be equal to 520 centimeters, not 0.52 centimeters.

5.2 meters = 52 decameters: This statement is incorrect. "Deca-" represents ten, so 52 decameters would be equal to 520 meters, not 5.2 meters.

52 meters = 520 decimeters: This statement is correct. "Deci-" represents one-tenth, so 520 decimeters is equal to 52 meters.

5.2 meters = 5,200 kilometers: This statement is incorrect. "Kilo-" represents one thousand, so 5.2 kilometers would be equal to 5,200 meters, not 5.2 meters.

Based on the analysis, the statement "52 meters = 520 decimeters" shows equivalent measurements. So Option C is correct.

In order to determine the sample size needed to achieve a desired margin of error for the population proportion, you will need to use a formula that takes into account the confidence level, the margin of error, and an estimate of the population proportion (p*).

However, since you do not have a reliable estimate of p*, you can use a conservative estimate of 0.5 to calculate the sample size. This will ensure that you have a large enough sample size to capture any changes in the population proportion, while still maintaining a reasonable level of precision in your estimate. Once you have collected your data, you can use the sample proportion as an estimate of the population proportion in any subsequent analyses.

Charmaine pays a monthly fee of a dollars for her phone service, and she pays an additional b cents per minute of use. The least she has been charged in a month is c dollars.

Solution:The least amount of charges that Charmaine paid in a month is c dollars. It is given that the monthly fee of Charmaine's phone service is a dollars. So, the amount charged per minute is given as (c - a) cents.

So, the least number of minutes she has used her phone in a month is c - a b cents. We can write this as an inequality as below: \(b(c - a) ≤ 100c\),

where 100c is the least amount of charges in dollars she paid in a month.

This can be simplified as:\(bc - ab ≤ 100c\)  --(1)

Solving for c, we get: c ≤ (100 × b)/(100 - b × a)   --(2)

From this, it is clear that c is positive if b × a < 100.

Therefore, we can say that the possible numbers of minutes Charmaine has used her phone in a month is c minutes such that: c ≤ (100 × b)/(100 - b × a),

if b × a < 100.

Since c represents the least amount of charges paid in a month, it must be a non-negative number.

Therefore, we can say that the possible numbers of minutes Charmaine has used her phone in a month is c minutes such that: c = ⌈(100 × b)/(100 - b × a)⌉, if b × a < 100.

Here, ⌈x⌉ represents the smallest integer that is greater than or equal to x.  Therefore, the possible numbers of minutes she has used her phone in a month are: c = ⌈(100 × b)/(100 - b × a)⌉ if b × a < 100.

Answer:

y = -2 + 5

Step-by-step explanation:

    To find the equation of a line when you only have two points you need to use the slope formula (y 2 -y 1) over (x 2 -x 1) Any set of points can be y 2, and x 2, just as long as you only use the ones in the same parenthesis as those values. I will use the points in A: (-1, 7) as my y2 and x2 values and my points B: (1, 3) as my y 1 and x 1 values. (7-3) over (-1-1) this gives me 4 over -2. Then I will solve out to get my slope by dividing 4 by negative 2.  This gives me that the slope of this line will be -2. Now, we need to find the y intercept. We get this by plugging in one of the sets of coordinates in for x and y in your half completed equation. So far we have y=-2x+b (b stands for y intercept) If we plug in the coordinates from coordinates B (1, 3), our equation looks like 3=-2(1)+b. Now, we solve this equation to find the y-intercept so we can complete the equation. First, multiply negative 2 by 1, you will get 3 equals -2 +b. Then add the two to both sides to cancel it out. Then you get that the y-intercept equals 5.

    Now you have all the pieces you need for your equation using standard form: y=mx+b. Plug in your slope for m, and the y intercept for b. You get: y equals -2 plus 5.

The equation of a line is a single representation of numerous points on the line.

The equation of line exists y = 2x + 1.

A line's equation is just one way to express all of the line's points. Any point on the line fulfills the equation for a line, which has the general form ax + by + c = 0. The slope of the line and a point on the line are the two elements that make up the line equation.

Let the two points be A(–1, 7) and B(1, 3).

= 3 - 7/ -1 -1

simplifying the above equation, we get

= -4/ -2

= 2

The equation of line be Y = mx + c

substitute the values in the above equation, we get

3 = 2(1) + c

simplifying the above equation, we get

⇒ 3 = 2 + c

⇒ 3 - 2 = c

The voter preference for the incumbent has a 95% confidence interval of 0.071 to 0.129.

A confidence interval is a range of values that are bound by the statistic's mean and that is likely to include an unidentified population parameter.

The proportion of probability, or certainty, that the confidence interval would include the real population parameter when a random sample is drawn numerous times is referred to as the confidence level.

So, we have the following confidence interval of proportions for a sample of n people who were surveyed with a success chance of π and a confidence interval of 1-a.

\(\pi \pm z \sqrt{\frac{\pi(1-\pi)}{n}}\)

When the z-score has a p-value of a, it is designated as b 1 - a/2.

We have this in relation to the issue:

A sample of 400 voters revealed that 360 supported the current governor. This indicates that the current governor is not in favor because 400-360 = 40.

So:

n = 400, π = 40/400 = 0.1

Now, the interval's lower limit is:

\(\pi-z \sqrt{\frac{\pi(1-\pi)}{n}}=0.10-1.96 \sqrt{\frac{0.10 * 0.90}{400}}=0.071\)

This range's maximum value is:

\(\pi+z \sqrt{\frac{\pi(1-\pi)}{n}}=0.10+1.96 \sqrt{\frac{0.10 * 0.90}{400}}=0.129\)

Step-by-step explanation:

The period of the graph of the function \(\(y = 2\cos\left(\frac{\pi}{2}x\)+3\))\) is 4.

The period of a cosine function is the distance it takes for the function to complete one full cycle or repeat itself. In this case, we have the function \(\(y = 2\cos\left(\frac{\pi}{2}x\)+3\))\).

The general form of the cosine function is \(\(y = A\cos(Bx+C) + D\)\), where A represents the amplitude, B represents the frequency or the reciprocal of the period, C represents the phase shift, and D represents the vertical shift.

Comparing our given function with the general form, we can see that A = 2, \(B = \(\frac{\pi}{2}\)\), C = 0, and D = 3.

The frequency or the reciprocal of the period is given by B. In this case, \(B = \(\frac{\pi}{2}\)\).

To find the period, we can use the formula:

Period = \(\(\frac{2\pi}{|B|}\)\)

Substituting the value of B, we get:

Period = \(\(\frac{2\pi}{\left|\frac{\pi}{2}\right|}\)\)

Simplifying further:

Period = \(\(\frac{2\pi}{\frac{\pi}{2}}\)\)

Period = 4

Therefore, the period of the graph of the function \(\(y = 2\cos\left(\frac{\pi}{2}x\)+3\))\) is 4.
