A nonlinear function that can be written on the standard form
<span><span>a<span>x2</span>+bx+c,wherea≠0</span><span>a<span>x2</span>+bx+c,wherea≠0</span></span>
is called a quadratic function.

Answer:
x = 6
Step-by-step explanation:
CT is a median, which means it divided AB into two equal parts so we can write the following equation:
7x + 9 = 5x + 21 transfer like terms to the same side of the equation
7x - 5x = 21 - 9 do the extraction
2x = 12 divide both sides by 2
<u>x = 6</u>
Answer:
a) 0.437; b) 0.291
Step-by-step explanation:
For part a,
There are 280+210 = 490 people that are over 18 years old. Out of these, 119+95 = 214 purchase 2 pairs of jeans annually. This is
214/490 ≈ 0.437
For part b,
There are 87+69+74+11 = 241 people who purchase 3 or more pairs of jeans. There were a total of 220+290+280+210 = 1000 people; this means there were 759 people tho purchased fewer than 3 pairs of jeans.
Out of these, 21+74+126 = 221 were in the age group 12-18. This gives us
221/759 ≈ 0.291
