A cat has a litter of six kittens. You plan to adopt 2 of the kittens. In how many ways can you choose 2 of the kittens from the litter?

Answers

Answer 1
Answer:

There are 15 ways to choose 2 of the kittens from the litter

How to determine the number of ways?

The given parameters are:

  • Litter = 6
  • To select = 2

The number of ways to select the 2 kittens is:

Ways = ^nC_r

This gives

Ways =  ^6C_2

The combination formula is:

^nC_r = (n!)/((n - r)!r!)

So, we have:

^6C_2 = (6!)/((6 - 2)!2!)

Evaluate the difference

^6C_2 = (6!)/(4!2!)

Expand

^6C_2 = (6 * 5 * 4!)/(4! * 2 * 1)

Evaluate the quotient

^6C_2 = 15

So, we have:

Ways = 15

Hence, there are 15 ways to choose 2 of the kittens from the litter

Answer 2
Answer: There are 6 kittens when you're deciding which one you want to pick, so there are 6 ways of chosing one. Then, the number of kittens lowers to 5, so there are 5 ways of picking another. At all, there are 30 ways of chosing 2 kittens out of 6.

What answer describes this sequence? 99, 89.9, 78.8, 68.7,...

a) Neither arithmetic nor geometric
b) Both arithmetic and geometric
c) Arithmetic
d) Geometric

Answers

a) Neither arithmetic nor geometric
a) Neither arithmetic nor Geometric

Explanation:
Since 99-89.9= 9.1, and 89.9 - 78.8 = 11.1, the sequence is not arithmetic.
Like wise 89.9/99=0.908 and  78.8/89.9 = 0.876 makes it not a geomtric sequence

Use a calculator to find each answer. Round to the nearest tenth.1.) 8392-(530+239)

You want to leave a nice tip on a $36 meal. So you decide to add 20% to the bill. How much is the total bill?

Answers

Answer:

43.20

Step-by-step explanation:

First find the tip

36 * 20 %

36 * .2

7.20

Then add the tip to the amount of the meal

36+7.20

43.20

You went to have a meal which costs $36, and maybe becoming very delighted with the taste and service of the food centre, you decided to add a tip.

  • 20\% of the total meal.

So, First we need to find the tip by multiplying the percentage with the cost of meal

Tip:

20\% \: of \: 36

(20)/(100) * 36

(1)/(5) * 36

7.2

Now, we have got the amount of money we decided to give as a tip. And, we are already having the cost of meal. So, total money paid:

36 + 7.2

\boxed{ 43.2}

This is our required answer.

If AB = 4x +10, BC = 2x +3 and AC= 9x - 15 find AC. and show work plzz !!!!

Answers

Answer:

Step-by-step explanation:

AB + BC = AC

4x + 10 + 2x + 3 = 9x - 15

6x + 13 = 9x - 15

6x + 13 + 15 = 9x

6x + 28 = 9x  

3x = 28

x = 9 1/3 = 28/3

AC = 9 * 28/3 - 15

AC = 3 * 28 - 15

AC = 84 - 15

AC = 69

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.
