In Design and Technology (D&T), when marking out plastic materials, various tools and techniques can be employed depending on the specific requirements and characteristics of the material. The choice of marking tools largely depends on the type of plastic and the desired outcome. Additionally, the drawing form used for marking out plastic typically involves the use of technical drawings or templates to ensure accurate and precise measurements.

Marking Tools:

1. Permanent Marker: A permanent marker with a fine tip is often used to make visible and long-lasting marks on plastic materials. It allows for clear lines and can be easily applied on smooth surfaces.

2. Scriber: A scriber, which is a sharp-pointed tool, can be used to scratch or score lines onto the plastic surface. This method is particularly useful for creating precise guidelines or marking out intricate shapes.

3. Masking Tape: Masking tape can be used to create temporary markings on plastic surfaces. It provides a clear boundary for cutting or shaping operations and can be easily removed without leaving residue.

4. Stencil: Stencils are pre-designed templates with cut-out shapes or patterns. They can be used to transfer specific designs or markings onto the plastic surface accurately.

Drawing Form:

1. Technical Drawings: Technical drawings, such as orthographic projections or isometric views, are commonly used in D&T to represent the shape, dimensions, and features of a plastic component. These drawings provide precise measurements, angles, and details necessary for accurate marking out.

2. Templates: Templates are pre-made patterns or outlines that are used as guides for marking out specific shapes or profiles onto the plastic material. Templates ensure consistency and accuracy in replicating complex shapes or designs.

Answer:

\(s = 11\)

Explanation:

Given

The attachment completes the question.

Required

Find s

Because ABCD and EFGH are similar, then:

\(\frac{AB}{CD} = \frac{EF}{GH}\)

From the attachment:

\(AB = 2s\)

\(CD = 3s - 3\)

\(EF = 5.5\)

\(GH = 7.5\)

So, we have:

\(\frac{2s}{3s - 3} = \frac{5.5}{7.5}\)

Cross Multiply

\(2s * 7.5 = 5.5(3s - 3)\)

Open bracket

\(2s * 7.5 = 5.5*3s - 5.5*3\)

\(15s = 16.5s - 16.5\)

Collect Like Terms

\(15s - 16.5s = - 16.5\)

\(-1.5s = - 16.5\)

Make s the subject:

\(s = \frac{-16.5}{-1.5}\)

\(s = \frac{16.5}{1.5}\)

\(s = 11\)

Hence, the value of s is 11 m

A function of the form \(f(x) = x^{-n}\), wherein n is a natural number, is regarded as a negative power function. Inside the form, we might also put \(f(x)\),that is\(f(x) = \frac{1}{x^n}\),and the further calculation can be defied as follows:

Given:

\(\bold{a)\ \sin 120^{\circ}}\\\\\bold{b)\ \sin 150^{\circ}}\\\\\bold{c)\ \cos 235^{\circ}}\\\\\bold{d)\ \cos 300^{\circ}}\\\\\)

To find:

Find negative function values =?

Solution:

\(\therefore \\\\\to \bold{\sin (180- \theta)= \sin \theta} \\\\\to \bold{\cos (180- \theta)= -\cos \theta} \\\\\to \bold{\cos (180+ \theta)= -\cos \theta} \\\\ \to \bold{\cos (360- \theta)= \cos \theta}\)

Solve value for a:

\(\to \bold{\sin 120^{\circ}= \sin(180-60)}\)

                  \(\bold{=\sin 60^{\circ}}\\\\\bold{=\frac{\sqrt{3}}{2}}\\\\\)

Solve value for b:

\(\to \bold{\sin 150^{\circ}= \sin(180-30)}\)

                  \(\bold{=\sin 30^{\circ}}\\\\\bold{=\frac{1}{2}}\\\\\)

Solve value for c:

\(\to \bold{\cos 235^{\circ}=-\cos( 180+55)}\)              

                  \(\bold{=- \cos 55^{\circ}}\\\\\bold{= -0.57357643635}}\\\\\)

Answer:

The probability of getting a girl is 12 . The probability of getting 6 girls is therefore (12)6 . Since we have 6 girls, we also need to find the probability of getting 2 boys, which is (12)2 . There are (86)=28 ways to get 6 girls out of 8 children.

Explanation:

Answer:

Explanation:

P(X > 6) = ?

P(X > 6) = P(X = 6) + P(X = 7) + P(X = 8)

P(X > 6) = 0.118 + 0.035 + 0.004

P(X > 6) = 0.157

Thus the probability of getting 6 or more girls in 8 births is 0.157

Answer:

3 groups of 5

Explanation:

if x is the number of groups of four, and y is the number of groups of five, then 4x +5y =39 (four students per group of four times the # of groups of four,   and 5 students per group times the # of groups of five, which should equal the total amount of students, 39). also, x+y=9. (number of each type of group = 9 groups total).

then, use these two equations and solve for y, by "canceling out" x. there are many ways to do this, but i'm going to use subtraction.

4x-5y=39

x+y=9

you want to change the equation

x+y=9

into

4x+4y=36

by multiplying the whole equation by four. because in order to cancel out the x, you need it to equal zero. in the first equation, its 4x.

so its now

4x-5y =39  MINUS

4x+4y=36

___________

y=3

you can check your work because the remaining 6 groups of four (24 total students) plus the 3 groups of five (15 total students) adds up to equal 36

The intervals suggest that both income and the age of the oldest family automobile are significantly associated with the odds of buying a new car.

How to explain the hypothesis

a. The confidence intervals for the odds ratio of buying a new car for families whose incomes differ by 20 thousand dollars and for the age of the oldest family automobile are as follows:

Income: (1.25, 3.75)

Age of oldest automobile: (1.10, 1.90)

These intervals suggest that both income and the age of the oldest family automobile are significantly associated with the odds of buying a new car.

b. The Wald test for whether X2, age of oldest family automobile, can be dropped from the regression model is as follows:

Test statistic = 2.25

P-value = 0.13

Since the P-value is greater than 0.05, we cannot reject the null hypothesis that X2 does not have a significant effect on the odds of buying a new car. Therefore, we cannot conclude that X2 can be dropped from the regression model.

c. The likelihood ratio test for whether X2, age of oldest family automobile, can be dropped from the regression model is as follows:

Test statistic = 2.25

P-value = 0.13

This result is identical to the result obtained for the Wald test in part (b). This is because the Wald test and the likelihood ratio test are asymptotically equivalent, meaning that they will have the same distribution as the sample size gets larger.

d. The likelihood ratio test for whether the following three second-order terms, the square of annual family income, the square of the age of the oldest family automobile, and the interaction between income and age, can be dropped from the regression model is as follows:

Test statistic = 12.6

P-value = 0.002

Since the P-value is less than 0.05, we can reject the null hypothesis that these three terms do not have a significant effect on the odds of buying a new car. Therefore, we can conclude that these three terms cannot be dropped from the regression model.

The number of cubic feet of water that it will take to fill the basin to a level of 1/2 foot from the top is 134 ft³

From the question, we are to determine the volume of water needed to fill the cylindrical basin to a level 1/2 foot from the top

Using the formula for calculating the volume of a cylinder

V = πr²h

Where V is the volume

r is the radius

and h is the height

From the given information,

Diameter of the basin = 8 1/4 feet = 8.25 feet

Radius = Diameter / 2

∴ r = 8.25/2 = 4.125 feet

Height of the basin = 3 feet

But, the basin is to be filled to a level of 1/2 foot from the top

Then,

The the basin would be filled up to 3 feet - 1/2 foot = 2 1/2 feet

∴ h = 2 1/2 feet = 2.5 feet

Now, putting the parameters into the equation, we get

V = π × 4.125² × 2.5

V = 133.64

V ≅ 134 ft³

Hence, the number of cubic feet of water that it will take to fill the basin to a level of 1/2 foot from the top is 134 ft³.The number of cubic feet of water that it will take to fill the basin to a level of 1/2 foot from the top is 134 ft³.
