Answer:
84 months
Step-by-step explanation:
Maria is 7 years old, there are 12 months in a year, multiply 12 by 7.
12 * 7 = 84
Maria is 84 months old
Ascending order= 6, 8, 12, 12, 12, 16
No of observations (n) = 6
Median = Mean of the values of (n/2) and (n/2+1)
= Mean values of 3rd and 4th values
= 12+12/2
= 12
Therefore, median = 12
Mode = Most number of observations= 12
Answer:
D
Step-by-step explanation:
Given
9 - 7x = (4x - 3)² + 5 ← expand the squared factor
9 - 7x = 16x² - 24x + 9 + 5, that is
9 - 7x = 16x² - 24x + 14 ( subtract 9 - 7x from both sides )
0 = 16x² - 17x + 5, that is
16x² - 17x + 5 = 0 ← in standard form → D
