3) A - Reflection

4) A - Online Practice

Further Explanation

Assessments that have the greatest effect on the overall grade of a student are summative tests. They measure the achievement of students based on the attainment of the learning objectives and given at the end of a chapter or unit. Typically, tests have a bigger portion or coverage, hence, given more weight compared to other assessments.

Quizzes and quick check are fast assessments that are given within the lesson to ensure understanding. They give quick feedback before the class moves on to the next part of the lesson. Discussions are verbal formative assessments that give teachers information about what a student knows or doesn't know. It is also a way to correct any misconceptions or push students more to develop their higher order thinking skills.

Sample work submission is usually not graded but is used as a reflection tool. This allows the student to evaluate his or her progress in the subject.

Students should do a reflection to evaluate their readiness for a major assessment. This self-assessment will give them ideas about what they are good at and what topics they need to focus on.

Immediate feedback may be obtained by online practice. These are usually short and quick assessments that can give a snapshot of what the student knows within the lesson. It is an example of a formative assessment.

Jasmine is building birdhouses. it takes her 3 1/2 hours to build 4 birdhouses. which of the following is a equivalent rate?a. 14 hours to build 18 birdhouses
b. 28 hours to build 35 birdhouses
c. 7 hours to build 8 birdhouses
d. 21 hours to build 28 birdhouses


plz help quick

Answers

Option C: 7 hours to build 8 house,

Whenever getting work-time related questions, it is needed to focus that as the amount of work done increases, the time needed to complete also increases.

Given that:

3.5 hours of work is needed to build 4 birdhouses.

Thus as we increase the time twice, the number of birdhouses build by the same person Jasmine will be twice as she got doubletime, thus building 2 times 4 i.e. 8 birdhouses.

Thus we have:

Jasmine takes 7 hours of work to build 8 birdhouses.

Therefore we see that Option C: 7 hours to build 8 birdhouses is correct.

>>> The equation T^2 = A^3 shows the relationship between a planet’s orbital period, T, and the planet’s mean distance from the sun, A, in astronomical units, AU. If planet Y is k times the mean distance from the sun as planet X, by what factor is the orbital period increased? <<

Answers

If planet Y is k times the mean distance from the sun than planet X, the right side of the equation becomes (kA)^3. which is k^3 times the left side, T^2. To equate both sides of the equation, multiply T by k^3/2 so that the left side becomes ((k^3/2) x T)^2 which simplifies into (k^3) x (T^2). Therefore, the answer is k^3/2. 

Answer:

Given the equation:

T^2 =A^3

shows the relationship between a planet's orbital period T and the planet's mean distance from the sun, A in Astronomical units

then:

For planet X:

Orbital period is:

T_(X) = (A)^{(3)/(2)}            .....[1]

As per the statement:

If planet Y is k times the mean distance from the sun as planet X.

⇒ A planet Y= kA mean distance from the sun as planet X.

then orbital period of Planet Y is:

T_(Y) = (kA)^{(3)/(2)}=k^{(3)/(2)}\cdot (A)^{(3)/(2)}    ....[2]

Divide equation [2] by [1] we have;

(T_(Y))/(T_(X)) = \frac{k^{(3)/(2)}\cdot (A)^{(3)/(2)}}{A^{(3)/(2)}}

Simplify:

(T_(Y))/(T_(X)) =k^{(3)/(2)}

or

T_(Y) =k^(3)/(2) T_X

Therefore, the orbital period is increased by factor k^(3)/(2)
