The length of strapping (in inches) needed to attach a pipe to the wall. Assume the wall is at a right angle and the straps connect to the wall at right angles is 31.77 in.

Given :

Length = 16.00 in diameter pipe

Now let determine or find the Length  since the diameter pipe is 16.00 in.

Length :

Length = 1.10 ×2 + 16.00 /2 × 2 + 1 /4 π · 16.00

Length = 3.20 + 16.00 + 4π

Length = 19.20 + 4π

Length = 31.766

Length = 31.77 inches  (Approximately)

The equation of a line is given by

where m is the slope of the line and (x1,y1) is a point where the line passes through.

In our case we have a point but we don't have the slope yet, so we have to find it. To do this we have to remember that two lines are parallel if and only if their slopes are equal, that is

We know that the line we are looking for is parallel to the line

we notice that this line in written in the slope-intercept form

then its slope is 13.

Since the line is parallel to the one we are looking for, our slope is also 13.

Using the point (9,12) and the slope the equation of the line is

now we have to write in the slope-intercept form

Therefore the line is

Step-by-step explanation:

A. 525 - 500 = 25

B. 0 - 80 = -80

C. 100 - 65 = 35

D. 2,500 - 2,597 = 97 shortage

so: -97

E. 2,650 - 2,502 = 148 surplus  

so: 148

A (0,2) B (5,4)

C(1,8) D( 3,3)

Apply the slope formula:

For AB

For CD

So both slopes are negative reciprocals of each other.

They are perpendicular lines.

For a polynomial to be in standard form, the terms are arranged from the highest exponent to the lowest exponent.

Thus, from the polynomials given, the polynomial in standard form is:

This is because the term with the highest exponent is the first term, the next exponent is 3, followed by the term with an exponent of 2, then the last term is the term with the least exponent.

The angles that are formed by the parallel lines and the transversal are:

1. Vertical Angles

2. Same-side Exterior Angles

3. Corresponding Angles

4. Alternate Interior Angles

5. Alternate Exterior Angles

6. Same-side Interior Angles

7. Adjacent Angles

The following are special angle pairs that are formed when a transversal intercepts two parallel lines:

1. Vertical Angles: These are nonadjacent angles that share the same vertex and are directly opposite each other. An example of such angle pair is angle 6 and angle 7.

2. Same-side Exterior Angles: These are exterior angles that lie on the same side of a transversal but on sperate parallel lines. Example include angle 2 and angle 8.

3. Corresponding Angles: These angles are located on each parallels lines that are cut across by a transversal and lie relatively in the same corner to each other. An example is, angle 1 and angle 5.

4. Alternate Interior Angles: an example of such pair of interior angles that lie on opposite side of a transversal is, angle 3 and angle 6.

5. Alternate Exterior Angles: An example of a pair of alternate exterior angle is angle 2 and 7.

6. Same-side Interior Angles: These pair of angles are interior angles on the same side of a transversal. Example of such pair of angles is, angle 4 and angle 6.

7. Adjacent Angles: These are angles that share a common side and a vertex, an example is: angle 1 and angle 2.

335 children should be in the park, if the ratio of children to adults at an amusement park is typically 5 to 3 and 201 adults are in the park.

A ratio is the comparison of two similar quantities or the proportion of one similar quantity to another. With the same meaning, ratios can be expressed in three different ways using words or symbols. In other words, ratios can be expressed by sandwiching a fraction bar, the word "to," or the ratio symbol ":" between the two values being compared.

The ratio of ninth-graders to tenth-graders can take on any of the three forms listed below, using the previous example of comparing the two groups of students in Ms. Jones' class:

Using the normal distribution, it is found that:

a) The variable used in this problem is: The time (in hours) a 4-year old spends unsupervised per day.

b) The distribution is: X ~ N(3, 1.8).

c) The probability is P(X < 1) = 0.1335, and is given by the bottom left graph.

d) The percentage of children who spend over 10 hours a day unsupervised is of 0.01%.

e) 90% of the children spend at least 0.7 hours unsupervised.

The z-score of a measure X of a normally distributed variable that has mean represented by [tex]\mu[/tex] and standard deviation represented by [tex]\sigma[/tex] is given by the following rule:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The variable used in this problem is:

The time (in hours) a 4-year old spends unsupervised per day, as the distribution involves only 4-year old children, and the mean and the standard deviation are measured in hours.

The mean and the standard deviation of the distribution are given, respectively, by:

[tex]\mu = 3, \sigma = 1.8[/tex].

Hence the distribution can be described approximately as follows:

X ~ N(3, 1.8).

The probability that a person spends less than 1 hour a day unsupervised is the p-value of Z when X = 1, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (1 - 3)/1.8

Z = -1.11

Z = -1.11 has a p-value of 0.1335.

The bottom left graph shows this probability, as the number in hours cannot be less than 0(there is no negative number of hours).

The proportion of children who spends over 10 hours a day unsupervised is one subtracted by the p-value of Z when X = 10, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (10 - 3)/1.8

Z = 3.89

Z = 3.89 has a p-value of 0.9999

1 - 0.9999 = 0.0001, hence the percentage is of 0.01%.

For item e, the measure is the 10th percentile, which is X when Z = -1.28, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

-1.28 = (X - 3)/1.8

X - 3 = -1.28 x 1.8

X = 0.7 hours.
