a.

Out of 15, 6 are green, rest are red.

No. of red apples = 15 - 6 = 9

Ratio of all apples in the basket to red apples

= Total no. of apples : No. of apples that are red

= 15 : 9

= 5 : 3

b.

No. of apples that are green = 6

No. of apples that are red = 9

Ratio of red apples to green apples

= No. of apples that are red : No. of apples that are green

= 9 : 6

= 3 : 2

Answer:

(A) It should choose High school Z for the most consistent attendance among its students.

(B) It should choose High school W with the highest average attendance.

Step-by-step explanation:

We are given the data for attendance in the table below, where Low represents the fewest days attended and High represents the most days attended for a single student.

<u>School</u>         Hight School W      High School X       High School Z

Low                       108                          112                          130

High                      180                          180                         180

Range                    72                           68                           50

Mean                    169                          160                          162

Median                 150                          124                          151

IQR                       47.5                         49.5                        39.5

S.D. (σ)                 29.5                         32.4                        27.5

(A) It is stated that the school district wants to award the school that has the most consistent attendance among its students.

Now, to check which high school should it choose; we will look for the standard deviation (σ) of each of the three schools because consistency is measured through standard deviation and the school with the lowest standard deviation means that it has the most consistent attendance among its students.

So, after looking at the standard deviation of all the three schools; the High School Z has the lowest standard deviation of 27.5.

This means that it should choose High school Z.

(B) It is stated that the school district wants to award the school with the highest average attendance.

Now, to check which high school should it choose; we will look for the Mean of each of the three schools because average is measured through mean of the data, and the school with the highest mean means that it has the highest average attendance.

So, after looking at the Mean of all the three schools; the High School W has the highest average of 169.

This means that it should choose High school W with the highest average attendance.

soldi70 [24.7K]

The quotient in polynomial form is C. x² - x ₊ 1.

<h3>What is synthetic division?</h3>

In algebra, synthetic division is a method for manually performing Euclidean division of polynomials, with less calculation than long division.

The given problem is-

-3 | 1  2  -2  3

Using synthetic division method,

-3 | 1  2  -2  3

   <u>|   -3    3  3 </u>

   |1   -1    1  6

So, the remainder from the calculation is 6 .

And the quotient polynomial is x² - x ₊ 1.

Hence, the correct answer for the given question is C. x² - x ₊ 1

From the two triangle, we can see that triangle ADE is a dilation of triangle ABC by a scale factor of 2.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

From the diagram:

AB = 3 units, AC = 4 units. Using Pythagoras theorem:

BC² = 3² + 4²

BC = 5 units

AE = 6 units, AD = 8 units. Using Pythagoras theorem:

DE² = 6² + 8²

DE = 10 units

From the two triangle, we can see that triangle ADE is a dilation of triangle ABC by a scale factor of 2.
