Answer:

x² + 9x + 20 = 0

Step-by-step explanation:

Given a solution x = - a for a quadratic equation then (x + a) is a factor

Here x = - 5 and x = - 4 , then corresponding factors are

(x + 5) and (x + 4)

The quadratic equation is then the product of its factors, that is

(x + 5)(x + 4) = 0 ← expand using FOIL

x² + 9x + 20 = 0

Hello! It would help a lot if I had assistance with this question:

Answers

Answer:

mode = 1

median = 2

mean = 3

Step-by-step explanation:

Here in this question, we want to calculate the given measures of central tendencies.

1. Mode

The mode refers to the number that has the highest frequency. The number here is the first number which is 1.

2. Median

This refers to the middle number after the numbers have been arranged in the descending or ascending order. Looking at the numbers, we have the middle number at the 8th term. The number at the 8th term is the number 2

3. Mean

The mean is the average of the numbers. It is calculated by summing up the numbers and dividing by the count of the numbers.

The sum of the numbers is;

1(7) + 2(3) + 3(1) + 5(2) + 8(1) + 11(1) = 45

The count of the numbers is 15

The mean is thus;

45/15 = 3
