Answer: x=-3
Step-by-step explanation:
2x-4(x+3)=x-3
2x-4x-12=x-3
-2x-12=x-3. add 12 to both sides
-2x=x+9. subtract x from both sides
-3x=9. Divide both sides by -3
x=-3
19^2 + x^2 = 21^2
19^2 = 361
21^2= 441
361 + x^2 = 441
x^2 = 441-361 = 80
x = sqrt(80) = 8.944 round to nearest tenth = 8.9
617.3/41=15.0560
It would be C and D since it says mark all that apply.
Answer: Rs. 5,033.30
Step-by-step explanation:
Total employees = 15 + 32 + 65 + 79 + 90 + 57 + 36 + 14 = 388
Median position = 388/2 = 194
Median therefore lies in range where cumulative employees is 194:
= 15 + 32 + 65 + 79 = 191
Median therefore lies in range after 4,000 - 4,999 which is 5,000 - 5,999.
Median = Lower limit of median range + range of median range * (median position - cumulative frequency up to median range) / frequency of median range
= 5,000 + 999 * (388/2 - 191)/90
= 5,000 + 33.3
= Rs. 5,033.30
