Mean = all numbers added up ÷ amount of numbers
So 22 + 24 + 26 + 20 + 29 + 28 + 26 = 175
175 ÷ 7 = 25 for mean
Median = middle number when arranged in order
20, 22, 24, 26, 26, 28, 29.
Middle number is 26.
Mode = most frequent number
Also 26 because it appears twice whereas all the other numbers only appear once.
Range = highest number - lowest number
29 - 20 = 9.
Answer: 7 +2x
Step-by-step explanation:
7 plus twice a number
Twice a number - 2x
7 plus 2x
Using the formula a² + b² = c² but reversing it to c² - b² = x² where x replaces the a for comprehension reasons
so this is the formula
c² - b² = x²
insert the numbers on the triangle in the picture
21² - 8² = 377
since 377 is squared and not the side length, we need to square root it to find x
√377 = 19.4~
Answer: x = 19.4

Answer:
Discriminant = 84
The polynomial has two real distinct roots
Step-by-step explanation:
Given:
To find: discriminant of the given function and number of distinct real zeros
Solution:
For a polynomial , discriminant is given by
If , then the polynomial has two real and distinct roots.
If then the polynomial has two real and equal roots.
If D<0 then roots are not real.
Here, in
a = 3, b = 12 and c = 5
As D > 0, the polynomial has two real distinct roots.
