Answer:
B
Step-by-step explanation:
The diagram shows two box plots.
Liam's box plot shows the median = 10
the range = 20 - 4 = 16
Sumat's box plot shows the median = 14
the range = 22 - 3 = 19
Difference between medians is 14 - 10 = 4
between ranges is 19 - 16 = 3
Thus, correct option is option B
Answer:
5
Step-by-step explanation:
Let's take the numerator first
3 1/2 - 9 3/4
Convert to improper fraction
7/2 - 39/4
Find the LCM
= -25/4
Now let's take the denominator
-2.5
Convert to fraction
-5/2
Combine the two parts of the fraction
-25/4 / (-5/2)
This becomes;
-25/2 * -2/5
= +5
Given that the vertex (h, k) is (5, 2), you know the vertex form will look like
f(x) = a(x -5)² +2
for some value of "a" that makes f(4) = -3. That value of "a" can be found by substituting the given values in the above equation for f(x) and solving for "a".
-3 = a(4 -5)² +2
-3 -2 = a×1²
a = -5
This means the appropriate choice is ...
C) Vertex form: f(x) = -5(x -5)² +2; Standard form: -5x² +50x -123
