2x - 24 = x - 2
2x - x = -2 + 24
x = 22
BC = x = 22
Calculating the z-score provides additional information regarding how each subject did overall as the z-score takes dispersion into account.
<h3>What is a z score?</h3>
Z-score indicates how much a given value differs from the standard deviation. For example, the mean of a test could be a 73 and if a student scored an 85, that's great.
However, if the data is not spread out, that 85 could be the highest in the class by 10 points. That's much more information than just 15 points above the mean. This way you can tell when someone not only did well but did exceptionally well in comparison to his or her peers.

Step-by-step explanation:
The general form of a linear equation is given by :
y = mx +b
Where
m is the slope
b is the y-intercept
(a) y = 2x - 3
It is in the form of a linear equation.
Standard form, y =2x+(-3)
(b) The equation is 4x = 2y
or
2y = 4x
y = 2x + 0
It is in the form of a linear equation with slope of 2 and y-intercept of 0.
You can factor x^2+6x+8 using the AC method.
Which would be: (x+2)(x+4)
Hope I helped.
I)
1 foot is a larger unit that 1 inch,
exactly: 1 foot = 12 inch.
ii) we add same units, that is we add feet to each other, and inches to each other:
<span>5 feet 9 inches + 12 feet 3 inches = (5+12) feet +(9+3) inches
=17 feet 12 inches
iii)
since 12 inches = 1 foot,
</span>17 feet 12 inches = 18 feet.
Answer: 18 feet
