**Step-by-step explanation:**

**To find : **Which terms could be used as the first term of the expression below to create a polynomial written in standard form? Check all that apply.

**Solution : **

The polynomials in standard form is written from higher degree to lower degree** i.e. in descending order.**

**The given polynomial has degree 6**: , and it can be ordered respect any of the two variables either r or s.

Adding a new term as first term needs to have degree equal or greater than 6.

**1)** cannot use as first term because its degree is less than 6.

**2)** it can be use as degree is 9.

is the standard form.

**3) ** it can be use as degree is 10.

is the standard form.

**4) ** it can be use as degree is 6.

is the standard form.

**Therefore, Option 2,3 and 4 are correct.**

7.4z−5(−1.6z+2.4) Expand the expression and combine like terms:

20(−1.5r+0.75) expand the expression and combine like terms

**Answer:**

**-30r + 15**

**Step-by-step explanation:**

We have been given that

20(−1.5r+0.75)

**Use the distributive property a(b+c)=ab+ac.**

20×(−1.5r)+20×0.75

**Multiplying, we get**

-30r +15

These two are not like terms. Hence , we cannot combine them.

Therefore, we cannot simplify it more.

**Hence, the simplified expression is -30r + 15**

** Problem-solving activity includes**

1.Understanding the problem,that is nature of the problem, then Completely define in your own way.

2. Determining why this problem has accrued,

3. Identifying the ways to solve the problem,

4. Prioritizing the given alternatives that is ways and then arranging the alternatives for a solution,

5. Then applying the best solution or arrangement for the given problem.

There are two ways considered for problem-solving activity

(1). Trial and Error (2) Reduction in steps

**It totally depends on the kind of problem , which you are solving. There may be Less than five alternatives ,equal to five alternatives or more than five alternatives to solve the problem.**

**Option B: False **

Radius of circle = 3 units

C = 2πr

C = 18.8 units

2. D

The distances between the points add to 24.

3. B

A = πr²

r = √(78.5/π)

r = 5 units

Point from options that is 5 units from (2,4) is (2,-1)

4. A

length of diameter = √[(5 - 1)² + (5 - 2)]

d = 5

r = 5/2

A = πr²

A = 25/4 pi units²

**1. a portion of a large group -> sample**

the sample is the part that you select from a population to analyze.

**2. choosing a sample so that every member has an equal chance of being chosen -> random sample**

in a random sample any member of the group has the same probabilities to be selected.

**3. choosing a sample from people who are under 15 years old -> biased sample**

when you select based on a characteristic of the group you are running a biased sampling.

**4. using the responses of a small group to make conclusions about the large group. -> estimating from a sample**

statistics searches to infere information about a large group using the responses from a sample

Let's calculate the common difference (c):

c = f(n + 1) - f(n)

9, –1, –11, –21, …

-1 - 9 = -10

-11 - (-1) = -11 + 1 = -10

-21 - (-11) = -21 + 11 = -10

Q2. The answer is c)3, –2, –7, –12, ...

f(n + 1) = f(n) – 5

f(n + 1) - f(n) = -5

c = f(n + 1) - f(n)

So, the common difference is: c = -5

Let's check all choices:

a) c = -5 - (-1) = -5 + 1 = -4 INCORRECT

b) c = 10 - 2 = 8 INCORRECT

c) c = -2 - (-3) = -5

c = -7 - (-2) = -5

c = -12 - (-7) = -5 CORRECT

d) c = 9 - 4 = 5 INCORRECT

Find the sum of the first 50 terms of the sequence below. An = 3n + 2

An+1 - An = 3n+5 -3n-2=3

An is aa arithmetic sequence

its sum is given by:

A0 +A1 +A2 + . . . + An = N(Ao + An) /2

where N = n-0=n

S50= A0 +A1 +A2 + . . . + A50 = 50(Ao + A50) /2

S50 = 50(Ao + A50) /2

Ao=2, A50=150+2=152

S50= 50(Ao + A50) /2

finally

S50=25*154=3850

ince the exam creator claims that on the same exam, nine times out of ten, seniors will have an average score within 6% of 80%, that means there is a 90% confidence interval. 9 / 10 = .90 = 90% 90% = 1.645 1.645 * .9 = 1.4805 Margin of Error - 1.4805

and The margin of error is the distance from x-bar, the center of the confidence interval ,to the end of the interval. This distance is 6% of 80% which is given by: 80×6100=4.8 Therefore the margin of error is 4.8% and the confidence interval is: ({80 - 4.8}%, {80 + 4.8}%)

The answer is choice B

y = (-A/B)x + C/B

where

-A/B is the slope

C/B is the y intercept

The only restriction is that B cannot be 0. This is to avoid a division by zero error. If B is zero, then the slope is undefined and you get a vertical line like with Ax = C
