|2x - 3| +4 = 17
Subtract 4
|2x - 3| = 13
Whatever is inside the Absolute must equal 13. Imagine it in our head, x = -5 is one solution, because it creates |-13| which becomes positive. Then we have x = 8, because that forms |16 - 3| = |13| = 13
Answer:
64
Step-by-step explanation:
59+5=64
Answer:
Step-by-step explanation:
From the given information:
suppose, the total number of people = n
Thus, the percentage of people believe in high school = 53% = 0.53
= n × m
The poll also let us understand that the number of people falls in margin error.
= ±n × M.O.E
where;
M.O.E = margin of error = ±5%
∴
the number of people falls in margin error. = ±n × 0.05 = 0.05 n
Thus, we can posit that the greatest percentage of people think for highschool was:
However, the least percentage of people think for highschool was:
<span> The geometric mean of two non negative numbers x and y is √(xy). (mean square root of XY)
So the geometric mean of 2/3 and 27/40 is
√(2/3 * 27/40)
= √(54 / 120)
= √(27 / 60)
= √(9 / 20)
= 3 / √20
= 3 / 2√5
= 3√5 / 10. </span>
