Answer:b
Step-by-step explanation:
A data with values
98,94,93,82,61,80 is given
If we arrange the number according to their values
61,80,82,93,94,98
Median of set
Now if 61 is removed then
80,82,93,94,98 are the remaining data
so New median is 93
So the median is increased by 5.5
Therefore option b is correct
Answer:
Now, 3x 2+x+5⩾0
This is because b² −4ac=1−4×5×3
=−59 (roots are imaginary)
3x²+x+5=(x−3)² =x²+9−6x and x−3⩾0
2x²+7x−4=0
2x²+8x−x−4=0
2x(x+4)−1(x+4)=0
(2x−1)(x+4)=0
x= 1/2 and−4 but x≥3
∴ No solution.
lol hehehe
I can't see the picture.
