The range of his scores is basically :
Subtract the highest score and the lowest score, and you find the range :
98 - 75 = 23
The range is 23..

The answer for this one would Be B
<span>We use the Pythagoras Theorem to derive a formula for finding the distance
between two points in 2- and 3- dimensional space.</span>
Let
P<span> = (x 1, y 1) </span>
Q<span> = (x 2, y 2) </span>
be two points on the Cartesian plane
<span>Then
from the Pythagoras Theorem we find that the distance between P and Q is</span>
PQ=((x2-x1)^2+(y2-y1)^2)^0.5
In a
similar way
it can
be proved that if
P<span> = (x 1, y 1, z1) and </span>
Q<span> = (x 2, y 2, z2) are two
points in the 3-dimensional space, </span>
<span>the
distance between P and Q is</span>
PQ=((x2-x1)^2+(y2-y1)^2+(z2-z1)^2)^0.5
<span>
</span>
Answer:
it might be D................
Y = x² - 10 x + 15 =
= (x² - 10 x + 25) - 25 +15=
= ( x - 5 )² - 10
Answer: y = ( x - 5 )²-10
vertex: (5, -10)
y - intercept: ( 0,15)
