Pupils that chose Band: 60%
Pupils that chose Chorus: 40%
Boys in band: 70%
Boys in chorus: 30%
Probability of choosing boy = Probability of boy in band + Probability of boy in chorus
P = 0.6 x 0.7 + 0.4 x 0.3
P = 0.54
The answer is D.
The Population mean is 3.3 and the Sample mean is 3.6, 3.6-3.3 is 0.3
Answer:
Slope = -1
Step-by-step explanation:
Since, slope of a line passing through two points
and
is given by,
Slope = 
Therefore, slope of a line passing through two points A(1, 4) and B(3, 2) will be,
Slope = 
= (-1)
Therefore, slope of the line is (-1).
We can tell that this absolute value function opens up, so the vertex will be at the x value where the output is the lowest. The lowest you can make |x+5| go is 0, because everything else will be a positive number is greater. The one x value that does that is -5. Plug in -5, and you will get |-5+5|-1=-1. So, the ordered pair for the vertex will be (-5,-1)
