Good morning ☕️
Answer:
<h2>(-∞ , -3/2)∪(3 , +∞)</h2>
Step-by-step explanation:
Here we have to solve this inequality 2x² - 3x - 9 > 0 for x.
In order to solve this inequality we need to factorize the expression at first:
2x² - 3x - 9 = 2x² - 3x - 3x + 3x - 9
= 2x² + 3x - (6x + 9)
= x(2x + 3) - 3(2x + 3)
= (2x + 3)(x - 3)
check the attached picture
conclusion:
the set of values of x for which y>9 is :
(-∞ , -3/2)∪(3 , +∞)

1. Is A. 25=3+2a and 2. Is A $3.19
I think it is B. and C.
secx = 3 and tanx = 3
Hope it helps
Step-by-step explanation:
1)......mean= sum of observations/ total observations
= 5.2+8.4+4.3+6.7+5.8/5= 6.08
median= n=5(odd)=n+1/2=6/2=3rdterm= 5.8( when arranged in ascending order).....
mode= 3median- 2meam= 3×5.8-2×6.08= 5.24
range=8.4-4.3=4.1(when done A.O)
2)......mean= -2-13-13-5-7/5= -8
median= 3rd term= -5.....(n=5..odd)(when done A.o)
mode=largest frequency= -13
range= -13-(-2) = -13+2= -11(A.O)
3).....mean= sum/no.= 8+6+13/2+17/2+15/2+7+8+11/2+7+8//10=7.2
median=n=10(even)
=
mode= 8
range=8.5-5.5=3
median:==
(10/2)+(10/2+1)//2=5 term + 6term/2=7+7.5=14.5/2=7.25
4)....
5)...remove 62...then 73will be having highest frequency
