The y intercept is 2, because that is the value of y when it crosses the y axis.
Since the line is pointing down, it has a negative slope, and since the y value goes down 2 for every 3 x values, the slope is -2/3. You should always right the slope in rise/run form, or change in y/change in x.
Finally, write the equation in the form of y=mx+b, where m is the slope and b is the y intercept. This means the equation of the line is y=-2/3x+2.
A is the answer because it is the widest variety
Answer:
if you mulitply (19*19*27*10*10) you get:
974700
Answer: The interquartile range= 12
Step-by-step explanation:
From the given the lower quartile 
= 42
the middle quartile 
= 49
The upper quartile 
= 54
We know that the interquartile range is given by:=-
Interquartile range= upper quartile- lower quartile or 
⇒
Hence, the interquartile range of the data displayed in this box-and-whisker plot is 12.
X^2 - 3x + p = 0
x^2 + qx + 7 = 0
αβ = p..........................(1)
3α + 3β = -q..................(2)
3α3β = 9αβ = 7
so substituting for αβ from (1):-
9p = 7
p = 7/9
α + β = 3 ( from first equation)
from (2) -q = 3 (α + β)
so -q = 3*3 = 9 and q = -9
Answer is p = 7/9 and q = -9
