Arranging the given distances from sea level on the number line, we have;
- The error made by taking Egypt as being further from the sea level is assuming that the sea level is at the beginning (left) of the number line.
<h3>How can the number line be used to find the distance from the sea level?</h3>
The given elevation of the lowest points in the six countries are;
Country. Lowest point elevation (m)
China. →. -154
Egypt →. -133
Azerbaijan → -28
Serbia. →. 35
Israel. → -408
Laos. →. 70
Sorting the above countries from the country with the lowest point below sea level to the country with the highest point above sea level gives;
Israel → -408
China → -154
Egypt → -133
Azerbaijan → -28
Serbia. → 35
Laos. →. 70
On a number line, we have;
Israel < China < Egypt < Azerbaijan < Serbia < Laos
Relative to zero, which is the sea level, points -133 and -154 are located to the left of zero.
However, point -133 > -154, therefore, -154 < -133, the symbol < represents lesser (in this case 'lower') which indicates that China (point -154) is lower or further left from zero which is the sea level than Egypt (point -133).
The error is therefore mistaking the location of the sea level as being at the extreme left of the number line, rather than at the middle.

#SPJ1
I haven't bought it yet but I am considering it, just wondering what the capacity is. I would be keeping tropicals in there, just small things like: neons, glass cat fish and my two mystery fish (see my other questions about them lol) and I would like to buy more neons (I have 6) and more glass catfish (I have two, though I'm looking at my SpyOrb as we speak and I appear to have lost them...they are hiding!). That is my answer
Answer:
1/2
Step-by-step explanation:
We assume your "a quarters" is a poor speech-to-text rendering of "eight quarters." If so, Selena has 16 coins, of which 8 are not quarters. The probability of choosing a "not quarter" is ...
8/16 = 1/2 = p(not quarter)
Answer:
option D
Step-by-step explanation:
Clearly from the graph we say that at x = 4 and x = -6, f(x) = 0
Now we will check this with your options.
A) f(x) = (x + 1 )² - 5
at x = 4, f(x) = 25 - 5 = 20 ≠ 0 ; not A
B) f(x) = x - 5
at x = 4, f(x) = 4 - 5 = 1 ≠ 0 ; not B
C) f(x) = (x + 1 )³ - 5
at x = 4 , f(x) = 125 - 5 = 120 ≠ 0 ; not C
D) f(x) = | x + 1 | - 5
at x = 4 , f(x) = | 4 + 1 | - 5
= 5 - 5 = 0 ; satisfies
at x = -6 , f(x) = | - 6 + 1 | - 5
= | - 5 | - 5
= 5 - 5 = 0 ; D satisfies [ | - a | =a , absolute value function ]
