What is the mean deviation method?.

184.04 ft high the tower with a lean of 6 degrees, the degree measure of this lean is 3.6 degrees and most likely because either the 13ft lean has not been measured to the top edge of the tower or the side of the tower isn't straight.

In the given question, the tower was 184.5 feet tall.

(a) If the article states that when work began the tower Leaned 6° or 13 feet, off the perpendicular then we have to draw a sketch and label the two measurements.

According to given statement the sketch is given below:

(b) We have to find how much high is the tower with a lean of 6 degrees.

From the graph using the Pythagorean Theorem:

H^2 = 184.5^2- 13^2

H^2 =34040.25-169

H^2 = 33871.25

Taking square root on both side

H=184.04 ft

(c) The article goes on to say that the tower now leans 16 inches less we have to draw a new sketch that shows this measurement.

The graph is given below:

(d) Now we have to find the degree measure of this lean.

We know that the tower leans 16 in less.

So 16in= 1 1/3ft = 4/3 ft = 1.33 ft

Consequently the lean after the work is: 13ft - 1.33= 11.67 ft

Then we can find the "lean" after the work as:

sin ("lean") =11.67/184.5

sin ("lean")= 0.0633

Angel of ("lean") after work = 3.6degrees.

(e) Now we have to find the height of the tower with this lean.

Height with reduced lean is found by using Pythagorean Theorem again:

H^2 = (184.5)^2 - (11.67)^2

H^2 = 34040.25 - 136.19

H^2 = 33904.06

Taking square root on both side, we get

H = 184.13

(f) Now comment on the fact that sin 4° =13/184.5 = 0.07046 while sin 6° = 0.10453. We have to check can we reconcile this seeming discrepancy.

Most likely because either the 13ft lean has not been measured to the top edge of the tower or the side of the tower isn't straight.

It says how many standard deviations the sample mean is away from the population mean.

A population is a collection of associated things or events that are important to a certain subject or experiment. A statistical population can be a group of actual objects or a fictitious, potentially infinite group of things developed from experience. The sample mean is the average value throughout the entire sample. The average value across the entire population is known as the population mean. If the sample was large and random, the sample mean would be a close approximation of the population mean. The standard deviation of a population is determined by taking the square root of the variance of the data set. When making judgments, it is used to compute a confidence interval.

The radius is 7.

Step-by-step explanation:

To find the radius of this circle, we would have to find the diameter first. This can be found by looking at both the directions of the origin (left and right) and counting how many spots it goes until the circle ends.

On the left, there is 6 spots. On the right, there is 8. So we would add to find the full way around or the diameter (6 + 8) and we get 14.

Now, since radius is halfway around or is half of the diameter, we simply divide 14 by 2 which is 7.

Therefore, the answer is 7.

Step-by-step explanation:

Each moth 5 dollars is charge and a one time fee of 10

(1) $132,000 is the net income

(2) $66,000 total income

Selling price per unit:

= Sales ÷ No. of units

= $456,000 ÷ 5,700

= $80

Variable cost per unit:

= variable cost ÷ No. of units

= $102600 ÷ 5,700

= $18

Alternative 1:

Contribution margin = Sales - variable cost

                                 = (5,700 × $80 × 1.1) - (5,700 × $18)

                                 = $440,000 - $210,000

                                 = $230,000

Net income = Contribution margin - Fixed cost

                  =  $230,000 - $98,000

                  = $132,000

Alternative 2:

Contribution margin:

= sales - variable cost

= $456,000 - ($456,000 × 59%)

= $456,000 - $236,000

= $164,000

Net income = Contribution margin - Fixed cost

For n is positive integer and d is a digit such that gives the numerical value and satisfied all given conditions. We get the base value i.e n is 9

and d = 2 . So, required value n+d = 11 .

We can start by setting up an equation to convert 32d base n to base 10. To convert this to base 10, it would be 3n²+2n+d. Because it is equal to 263, we can set this equation to 263. Finally, subtract d from both sides to get

3n²+2n = 263-d.

We can also set up equations to convert 324 base n and 11d1 base 6 to base 10. The equation to covert 324 base n to base 10 is 3n²+2n+4. The equation to convert 11d1base 6 to base 10 is 6³+ 6²+6d+1.

Simplify , 6³+6²+6d+1 so it becomes 6d+253. Setting the above equations equal to each other, we have3n²+2n+4 = 6d+253. Subtracting 4 from both sides gets 3n²+2n = 6d+249.

We can then use equations

3n²+2n = 263-d

3n²+2n = 6d+249 to solve for d.

Set 263-d equal to 6d+249 and solve to find that d=2.

Plug d=2 back into the equation 3n²+2n = 263-d. Subtract 261 from both sides to get your final equation of 3n²+2n-261 = 0.

We solve using the quadratic formula to find that the solutions are 9 and -10. Because the base must be positive, n=9.

Trigonometric expressions are equations that contain the trigonometric ratios.

Given the trigonometric expression

(cos²α - cot²α)/(sin²α - tan²α)

To simplify the expression, we proceed thus

(cos²α - cot²α)/(sin²α - tan²α) = (cos²α - 1/tan²α)/(sin²α - tan²α)

= (cos²α - [cos²α/sin²α])/(sin²α - [sin²α/cos²α])

=  (cos²α - [cos²α/sin²α])/(sin²α - [sin²α/cos²α])

Factorizing out cos²α and sin²α, we have

=  (cos²α - [cos²α/sin²α])/(sin²α - [sin²α/cos²α])

=  cos²α(1 - 1/sin²α])/(sin²α(1 - 1/cos²α])

= [cos²α(sin²α - 1)/sin²α]/[sin²α(cos²α - 1)/cos²α]

= cos²α(sin²α - 1)/sin²α × cos²α/[sin²α(cos²α - 1)

= cos²α × -(1 - sin²α)/sin²α × cos²α/[sin²α × -(1 - cos²α)

= cos²α(1 - sin²α)/sin²α × cos²α/[sin²α(1 - cos²α)

= cos²α × cos²α/sin²α × cos²α/[sin²α × sin²α] (since cos²α = 1 - sin²α and sin²α = 1 - cos²α)

= cos²α × cos²α × cos²α/[sin²α × sin²α × sin²α]

= cos⁶α/sin⁶α

             = 28,650 × ( 1 + 6.8/100 ) ^10

             = 28,650 × ( 1 + 0.068 )^10

             = 28,650 × 1.930689

             = $55,314.2

Increase in interest amount for increase in rate of interest from 5.05% to 6.8%

=  $( 55,314.2 - 46,890.6 )

= $8423.6

=$8424 ( nearest dollar)

Therefore,  for the given average principal $28650 of per student loan at the rate of interest increases from 5.05% to 6.8% , the amount of interest increases for the period of 10 years is equal to $8424 (nearest dollars).

The order of H can be |H| = 84, or |H| = 210 or |H| = 420.

In the mathematical field of group theory, Lagrange's theorem is a theorem that states that for any finite group G, the order (number of elements) of every subgroup of G divides the order of G.

By Lagrange's Theorem, we know |K| divides |H|, so |H| = 42k for some k (bigger than 1 since K is a proper subgroup of H).

Likewise, 42k divides 840, so k divides 840/42 = 20.

Since H is a proper subgroup of G, we know k < 20,

so either k = 2 , k = 5 or k = 10, and

Hence either |H| = 2(42) = 84, or |H| = 5(42) = 210 or |H| = 10(42) = 420.

The relevant parameter of interest for this numerical variable would be the average filling weight of all cereal packages.

What is the standard deviation in statistics?

The standard deviation in statistics is a measure of the amount of variation or dispersion in a set of values. A low standard deviation indicates that the values are close to the set's mean, whereas a high standard deviation indicates that the values are spread out over a larger range.

If a machine that is programmed to package 1.20 pounds of cereal is being tested for its accuracy. in a sample of 36 cereal boxes, the sample mean filling weight is calculated as 1.22 pounds. the population standard deviation is known to be 0.06 pounds.

The parameter of interest is the average filling weight of all cereal packages.

Hence, the relevant parameter of interest for this numerical variable would be the average filling weight of all cereal packages.

What is the slope of the line in the slope-intercept form of the line?

If y = mx + c line is given then 'm' represents the slope of the line. If any pair of lines are given and if they have the same value of the slopes then we can say that the given pair of lines will be parallel in nature and if the slope of the one line is the negative inverse of the other line then we can say that the pair of lines are perpendicular to each other.

For example 1:

      y = 3x + 4 and y = 3x +7

     The slopes of both lines are equal hence, these pair of lines are parallel.

For example 2:

     y = -4x + 1 and 4y = x + 3

    Here, the slope of one line is the negative inverse of the other line hence this pair of lines are perpendicular to each other.

For example 3:

     y = 2x - 5 and y = 5x -5

   In this, the slopes are not equal so we can say that the graph of this pair of equations is not parallel nor perpendicular.

For example 4:

     y = -1/3x + 2 and y = 3x - 5

     Here, the slope of one line is the negative inverse of the other line hence this pair of lines are perpendicular to each other.

For example 5:

     y = 3/5x - 3 and 5y = 3x - 10

    The slopes of both lines are equal hence, these pair of lines are parallel.

For example 6:

     y = 4 and 4y = 6

     The slopes of both lines are equal hence, these pair of lines are parallel.

For example 7:

     y = 7x + 2 and x + 7y = 8

     Here, the slope of one line is the negative inverse of the other line hence this pair of lines are perpendicular to each other.

For example 8:

     y = 5/6x - 6 and x + 5y = 4

    In this, the slopes are not equal so we can say that the graph of this pair of equations is not parallel nor perpendicular.

Hence,

Example 1: Pair of lines are parallel.

Example 2: Pair of lines are perpendicular.

Example 3: Pair of lines are not parallel nor perpendicular.

Example 4: Pair of lines are perpendicular.

Example 5: Pair of lines are parallel.
